1 Background and Purpose 

The purpose of this report is to present Sacramento Area Flood Control Agency’s (SAFCA’s) 

most current cost estimates for the Natomas Levee Improvement Program (NLIP) and to 

compare these estimates to estimates prepared by the U. S. Army Corps of Engineers (USACE). 

The USACE estimates appear in the report recently submitted to Congress entitled Post- 

Authorization Report and Interim Reevaluation Report, American River Common Features 

Project, Natomas Basin, Sacramento and Sutter Counties, California (PACR). 

SAFCA’s cost estimates for the NLIP consist of eight principal accounts including Fish and 

Wildlife Facilities, Levees and Floodwalls, Internal Drainage Pumping Plants, Lands and 

Damages, Relocations, Planning, Engineering and Design, Cultural Resources and Construction 

Management. These accounts are subdivided into nine geographic reaches (A through I) 

extending around the perimeter of the Natomas Basin as shown in Figure 1. Each account 

includes cost estimates for the SAFCA 200-year project, which is being designed to meet the 

State of California’s (State’s) requirements for levee-protected urban areas in the Central Valley. 

These estimates are supported by the detailed analyses contained in the attached Appendices A 

through E. 

This report also compares SAFCA’s cost estimates for the 200-year project to cost estimates 

prepared by USACE for the National Economic Development (NED) Plan. This NED Plan 

reflects current USACE planning and engineering standards. It generally contains the same 

features as the SAFCA 200-year project, however the NED Plan has a slightly smaller footprint 

than the SAFCA project along the Natomas Cross Canal (NCC) south levee and the upper 12 

miles of the Sacramento River east levee. In these reaches (B, C and D), the SAFCA project 

includes raising the levees up to three feet, while the NED plan does not contain any levee raises. 

There are also differences in the footprints of the two plans along the levees on the east side of 

the Natomas Basin (Reaches E, F, G and H). These differences are highlighted in the 

Engineering Appendices and reflect variations in design assumptions between the SAFCA 200- 

year project and the USACE NED Plan for the levee improvements in these reaches. 

2 Approach to SAFCA Cost Estimates 

SAFCA has already constructed nearly one-third of the 200-year project and expects to complete 

nearly one-half over the next two years. The completed work will encompass Reaches D and C 

and most of Reach B. SAFCA’s cost estimates for this work reflect actual costs incurred to date 

and near-term projections based on completed design documents that are currently out for bid. 

The remainder of the 200-year project will be constructed by USACE. Designs for this work are 

about 90 percent complete for the remainder of Reach B, 60 percent complete for Reaches E and 

H, and about 30 percent complete for Reaches A, I, F and G. SAFCA’s estimates for this portion 

of the 200-year project reflect opinions of probable cost developed by SAFCA’s engineering, 

real estate, and environmental consultants. Cost contingencies have been added to these 

estimates to reflect remaining design uncertainties and all of the estimates have been escalated to 

reflect SAFCA’s understanding of the likely sequence and timing of USACE construction. 

1

2.1 Fish and Wildlife Facilities 

This account covers the costs of the land, facilities and long-term management efforts necessary 

to compensate for the environmental effects of the 200-year project in six habitat categories: 

woodlands, cropland, managed marsh, canal/jurisdictional waters, grasslands, and shaded 

riverine aquatic (SRA). The extent of the required compensation in each category is specified in 

environmental documents and permits that have been prepared and adopted in connection with 

the project. The cost estimates for the required mitigation are summarized in Appendix A. 

In many instances, compensation lands and facilities serve a dual purpose. For example, most of 

the lands used to preserve or create cropland and managed marsh also serve as sources of borrow 

material for levee construction. Because the end use of these lands is for habitat compensation, 

the cost estimate assigns the entire cost of the land to the Fish and Wildlife Facilities account. 

The costs allocable to the new GGS/Drainage Canal are also assigned to the Fish and Wildlife 

Facilities account. This facility will allow the Sacramento County Airport System (SCAS) to 

abandon a potentially hazardous drainage and irrigation ditch directly adjacent to the Airport’s 

western runway and relocate these functions to the new canal. Without this relocation, it is 

doubtful that SCAS would have agreed to provide borrow material from its Airport lands for the 

project. The new canal also provides important canal and related aquatic habitat value to offset 

project impacts to waters and habitats protected under the Federal Clean Water Act. Since this is 

the canal’s principal long-term purpose, the costs for constructing, planting and managing the 

new canal and acquiring the land it occupies have been included in the Fish and Wildlife 

Facilities account. 

Native grassland costs are also assigned to this account. These grasslands will occupy flood 

control and irrigation facilities in the project footprint that have a primary purpose other than fish 

and wildlife compensation. Thus, while the land acquisition and long-term maintenance costs of 

these facilities are assigned based on these primary purposes, the cost of planting and 

establishing native grasslands is assigned to the Fish and Wildlife Facilities account. 

Estimates of the land costs included in this account are based on actual costs incurred or the 

projections outlined in the discussion of Lands and Damages below. Costs for site preparation, 

planting and plant establishment for grasslands, woodlands and croplands are estimated based on 

actual costs incurred to date. Costs for managed marsh site development include costs for the 

drainage and irrigation infrastructure needed to serve these sites. These costs are based on 

consultant opinions of probable cost. Costs for marsh site preparation and planting are derived 

from estimates provided by the Natomas Basin Conservancy (TNBC). Long-term management 

costs for woodlands are derived from consultant estimates based on models developed by the 

Center for Natural Lands Management (CNLM). Long-term management costs for cropland and 

managed marsh are derived from models developed by TNBC in connection with the Natomas 

Basin Habitat Conservation Plan (or NBHCP).

2.2 Levees and Floodwalls 

This account covers the cost of constructing the flood control features of the project including 

reconfiguring, raising, and reconstructing levees, constructing landside seepage berms, installing 

cutoff walls, and carrying out related levee improvements. As set forth in Appendices B and C, 

the key drivers in this account are the estimated costs for obtaining, hauling and placing 

embankment borrow material and the estimated costs for installing cutoff walls. 

SAFCA’s cost estimates for the 200-year project assume that levee improvement activities will 

require about 10 million cubic yards of borrow material. To date, SAFCA has excavated, hauled 

and placed about 40 percent of this volume as part of improvement efforts along the NCC south 

levee and the upper portion of the Sacramento River east levee. The borrow sites for this material 

have all been located within close proximity to the levee system, generally no more than three or 

four miles from the furthest construction site. This has allowed relatively short, off-road haulage 

of materials. Access to these materials has been obtained in three ways: 

 

 

 

acquisition of the land with the goal of later converting this land to use as project 

mitigation (no land cost assigned to the Levees and Floodwalls account); 

acquisition of the land without conversion to mitigation (cost of the borrow material is 

deemed to be equal to the cost of the land and assigned to the Levees and Floodwalls 

account); and 

acquisition of the right to take the borrow material without acquiring the land (cost of the 

right to take assigned to the Levees and Floodwalls account). 

These acquisition costs are referred to as “Borrow Royalty/Land” costs. SAFCA’s cost estimates 

assume that Borrow Royalty/Land costs for the remainder of the 200-year project will reflect all 

three of these acquisition modes. For the remaining work along the Sacramento River, borrow 

sources have been identified and arrangements have either been made or are in process. For the 

remaining work along the east side of the Basin where potential sources have been identified but 

no agreements have been struck, the estimates rely on a blended rate derived from the borrow 

costs incurred to date. 

With respect to unit costs for borrow excavation, haulage and placement and cutoff wall 

installation, the estimates for the work to be performed by the USACE represent consultant 

opinions of probable cost. The estimate unit costs are higher than the actual unit costs incurred to 

date to account for the potential for construction prices to experience a moderate rebound from 

more favorable 2009 and 2010 levels. Borrow quantities (cubic yards) and cutoff wall quantities 

(square feet) reflect engineering consultant estimates based on current designs. 

2.3 Interior Drainage Pumping Facilities 

This account covers reconstruction of interior drainage pumping facilities interrupted by levee 

improvements. As described in Appendix D, there are eleven such facilities in the project 

footprint. Eight of these facilities are owned and operated by Reclamation District No. 1000 (RD 

1000) and three are owned and operated by the City of Sacramento. One of these facilities (RD 

1000’s Pumping Plant 2) has been demolished as part of the work accomplished to date. This 

facility will be reconstructed along with the other ten facilities as part of the USACE portion of 

3

the project. Lacking actual costs, the estimates for this work reflect engineering consultant 

opinions of probable cost based on 30 to 90 percent plans for the remaining facilities. 

2.4 Lands and Damages 

As set forth in Appendix E, this account covers cost estimates for the land needed to 

accommodate the 200-year project footprint, provide borrow material for levee improvements 

and irrigation canal construction, and compensate for the impacts of the project on fish and 

wildlife habitats. These estimates reflect the influence of the Natomas Basin Habitat 

Conservation Plan, the location of the Airport in relation to portions of the 200-year project in 

Reaches B and C, and recent trends in land use planning for the unincorporated portions of the 

Natomas Basin in Sutter and Sacramento Counties. Thus, while most of the land that is needed to 

support the project is currently agricultural in nature, the value of this land reflects the 

anticipation of most landowners in the Basin that substantial additional urbanization will occur in 

Natomas accompanied by the retirement of development rights on a sufficient amount of land to 

meet the requirements of the NBHCP. 

To date, SAFCA has acquired several hundred acres of land in the northern and western portions 

of the Natomas Basin. The acquisitions have often occurred either under threat of condemnation 

or as the direct result of condemnation proceedings. This process has provided significant 

benchmarks for valuing land in the 200-year project, particularly in the areas of the Basin that 

are outside the urban core south of Elkhorn Boulevard and east of Interstate 80. SAFCA's 

estimates reflect actual costs incurred or they are projections based on comparable land values 

encountered to date for similarly situated lands. 

Administrative costs associated with land acquisition include costs for property boundary and 

hazardous materials surveys, site investigations, appraisals, legal process, etc. SAFCA’s 

estimates reflect actual costs incurred or they are projections based on a percentage of expected 

land costs. The administrative costs are assumed to be 40 percent of the land value for the 

mitigation land and project footprint including contingencies. This estimate is high based on 

SAFCA’s past experience. This higher cost anticipates the need for more extensive agency 

coordination during the USACE lead portion of the project. The actual percentage varies by 

reach due differences in escalation and the use of actual costs. 

2.5 Relocations 

This account covers facility relocations other than interior drainage pumps. This is a substantial 

account considering the size of the 200-year project footprint. It includes relocation of electrical 

utility poles at the landside toe of existing levees, structural demolition and tree removal, 

relocation of irrigation facilities including pumping plants, canals and wells; and relocation of 

roadways and bridges, particularly along the east side of the Basin. The irrigation facility 

relocations are described in Appendix D. The electrical utility and roadway relocations are 

covered in Appendices B and C. 

SAFCA has carried out much of this relocation work as part of the project construction effort to 

date and the costs incurred in this work have informed the estimates for the 200-year project. 

Notably, as in the case of the interior drainage pumping plants discussed above, SAFCA has not 

reconstructed any of the irrigation pumps in the project footprint in Reaches B and C. This work 

4

will be performed by USACE. The USACE project will also include more substantial roadway 

and bridge relocations than have thus far been encountered by SAFCA. SAFCA’s estimates for 

this work reflect engineering consultant opinions of probable cost based on 30 to 90 percent 

plans for the affected facilities. The one exception is for the bridge relocations costs, which are 

based on the square foot unit costs for other bridge replacement projects. 

2.6 Planning, Engineering and Design 

This account covers the cost of consultant services and SAFCA staff time allocable to project 

planning, engineering and design. It includes agency planning and coordination, environmental 

review and permitting, civil and landscape design, surveying, geotechnical investigation and 

analysis, general engineering services, compliance with Central Valley Flood Protection Board 

(CVFPB) and USACE permits and permissions, and peer review. SAFCA’s estimates reflect 

actual costs incurred and projections based on a percentage of anticipated construction costs (for 

fish and wildlife facilities, levee and floodwall improvements, and interior drainage pumping 

plant improvements) and relocation costs. The projected costs vary as a percentage of the total 

construction costs by reach due differences in escalation and the use of actual costs. 

To date, SAFCA has incurred engineering and design costs at an unusually high rate compared to 

construction and relocation costs. This reflects prevailing market conditions in which 

construction and relocation costs have markedly softened but professional services costs have 

not. In addition, SAFCA has incurred unusually high engineering and design costs because the 

200-year project has moved forward at a rapid pace in an uncertain engineering environment 

created by new and evolving state and federal levee design standards. As a result, SAFCA has 

incurred substantial costs for geotechnical exploration and analysis to address evolving standards 

for identifying and remediating underseepage vulnerability. SAFCA has also incurred substantial 

engineering and design costs related to complying with new federal standards for levee 

vegetation and encroachments. 

In order to meet these standards, SAFCA altered the initial design of the 200-year project and 

developed the adjacent levee design being implemented along the Sacramento River. This new 

design has triggered a series of collateral design and engineering costs as the expanded footprint 

of the 200-year project has compelled SAFCA to address numerous federal and state endangered 

species, aviation safety and cultural resource preservation requirements unique to the western 

portion of the Natomas Basin. This process has occurred principally in Reaches B and C where 

the redesign and re-engineering effort has been most intense and costly. 

By contrast, in Reach D, the planned improvements were already essentially compliant with the 

new vegetation and encroachment standards and no significant redesign was necessary. As a 

result, the costs for engineering and design services in this reach represent a much smaller 

percentage of total construction and relocation costs. SAFCA’s estimates for the remainder of the 

project in this account more closely reflect this Reach D percentage. 

2.7 Cultural Resources 

This account covers costs associated with compliance activities under the National Historic 

Preservation Act. Because of the landward expansion of the existing levee footprint along the 

east side of the Sacramento River, the SAFCA project has encountered numerous Native 

5

American burial sites containing human remains and culturally significant artifacts. This has 

spawned significant and costly monitoring, recovery and reburial activities particularly in 

Reaches B and C. Going forward, SAFCA’s estimates for this account anticipate a decline in 

costs as the project moves into the lower portion of the Sacrament River east levee and around to 

the east side of the Basin where the chance of encountering burial grounds or other sensitive 

resources is diminished. 

2.8 Construction Management 

This account covers construction management activities. SAFCA has completed enough project 

construction to provide reasonable benchmarks for this category of activities. The SAFCA 

construction management cost estimates utilize actual construction management costs for 

completed work or work nearing completion. The SAFCA projected construction management 

estimates assumes future construction management costs will be 15 percent of the total cost to 

complete construction and relocation activities. This is higher than the estimate used in some 

reaches by the USACE of 8 percent of the cost to complete the construction and relocation 

activities. The SAFCA estimate used the 15 percent assumption because it is more representative 

of what SAFCA has been experienced during implementation. The higher percentage for 

construction management experienced by SAFCA may be due to the recent down turn in the 

economy and the favorable construction bids that have been received to date. SAFCA’s estimates 

anticipate that this percentage will continue for the remainder of the project with a modest 

upward adjustment to account for the USACE portion of the project. 

2.9 Contingencies 

For the portion of the 200-year project that has been completed by SAFCA or will be completed 

over the next two years (Reaches D and C and most of Reach B), SAFCA’s cost estimates 

contain relatively small contingencies (5 to 10 percent). Higher contingencies (25 to 30 percent) 

are assigned to project cost estimates in the other reaches to be completed by USACE. These 25 

to 30 percent contingencies are added to unit cost and land value estimates for project features in 

these reaches that already reflect the highest values encountered by the SAFCA project to date. 

2.10 Escalation 

In order to reflect potential changes in the current engineering and construction cost 

environment, the SAFCA estimates include a 3.2 percent per year cost escalation. The escalation 

rate is based on the average annual escalation rate reported over the last 20 years in the 

Engineering News and Record Construction Cost Index. The escalation rate is applied based on 

SAFCA’s current assumptions regarding the sequence of when USACE engineering design and 

construction activities will occur over the next six years. 

6

3 Comparison to USACE NED Plan by Reach 

Comparing SAFCA’s estimates for the 200-year project to USACE’s estimates for the NED Plan 

reveals several differences mainly affecting four accounts: Lands and Damages, Levees and 

Floodwalls, Construction Management, and Relocations. These differences seem to reflect three 

tendencies in the USACE approach. First, USACE tends to include higher land costs by adopting 

conservative project designs and per acre land values. Second, USACE tends to escalate unit 

costs for borrow material excavation, hauling and placement and cutoff wall installation beyond 

the costs actually incurred in connection with the SAFCA project and beyond the opinions of 

cost prepared by SAFCA’s design consultants. Third, USACE tends to include conservative 

estimates for particular cost categories, notably construction management. The resulting cost 

differences are magnified by the USACE’s use of contingencies that are higher than those used 

by SAFCA. 

These differences are best highlighted by comparing the two estimates on a reach by reach basis 

as set forth below. 

3.1 Reach A (Sacramento River East Levee - San Juan Road to I-5) 

Reach A extends for 25,100 feet along the Sacramento River east levee from San Juan Road to 

the Interstate 5 overpass near the mouth of the American River. The 30 percent design for this 

portion of the project anticipates that the existing levee will be widened by about 24 feet but not 

raised. Underseepage vulnerability will be addressed through a combination of landside seepage 

berms and cutoff walls. Three large interior drainage pumping facilities will be reconstructed; 

and about two miles of the Riverside Irrigation Canal will be relocated along with more than 100 

electrical utility poles. Completing this portion of the 200-year project will require a design that 

accommodates a large PG&E tower near the landside toe of the levee at Station 847+00, the 

bridge piers and footings supporting the Interstate 80 overcrossing of the levee; and urban 

subdivisions along the landside toe of the levee east of Interstate 80. SAFCA’s cost escalation 

assumes that planning and design will occur in 2012, followed by land acquisition in 2012 and 

2013, with the construction contract awarded late in 2013. 

3.1.1 Fish and Wildlife Facilities 

The 200-year project in Reach A will cause significant impacts to woodland, and 

cropland habitats due to removing trees along the landside toe of the existing levee and 

occupying existing agricultural lands within the footprint of the relocated Riverside 

Irrigation Canal. These impacts will be offset by created woodland, cropland, and 

grassland facilities in Reach B and in the Dry Creek floodplain east of Natomas. 

SAFCA’s cost estimates for these facilities reflect actual and projected land acquisition 

costs; projected site preparation, planting and establishment costs based on contracts 

awarded as part of SAFCA’s SREL 2 project in Reach C; and long-term management 

costs derived from the Natomas Basin Habitat Conservation Plan (NBHCP) and Center 

for Natural Lands Management (CNLM) models. This estimate includes a 10 percent 

contingency for land acquisition and a 5 percent contingency for mitigation site 

development. 

7

SAFCA’s estimate for fish and wildlife facilities in Reach A is substantially larger than 

the USACE estimate. The basis for this difference is unclear. 

3.1.2 Levees and Floodwalls 

SAFCA’s estimates for levee and floodwall construction in Reach A are based on the 

design consultant’s opinion of probable cost. These costs are significantly higher than the 

unit prices for levee and floodwall construction actually incurred in Reaches B and C. 

The SAFCA estimates assume that levee, seepage berm and irrigation canal construction 

in this reach will require approximately 1.5 million cubic yards of borrow material. The 

Borrow Royalty/Land cost is approximately $10.7 million. This includes the cost of 

acquiring 280 acres of land south of Fisherman’s Lake which will serve as the primary 

source of this material and the cost of obtaining the right to take a small amount of 

surplus material from the Twin Rivers School District site along the Natomas East Main 

Drainage Canal (NEMDC) near Elkhorn Boulevard. 

The USACE estimate for levee and floodwall construction in Reach A is about 40 percent 

higher than the SAFCA estimate. This difference reflects USACE’s higher unit costs for 

borrow activities and cutoff wall construction. In addition, the USACE estimate assumes 

that the landside slope of the levee adjacent to the urban subdivisions in the lower portion 

of Reach A will be flattened to achieve a 3:1 slope. USACE also assumes that a 15-foot 

maintenance corridor will be added at the landside toe of the expanded levee. The 

SAFCA estimate assumes that the top of the levee in this area will be degraded prior to 

cutoff wall installation and then the levee will also be reconstructed to a 3:1 slope. The 

USACE estimate includes a 32 percent contingency compared to the 30 percent 

contingency on the levee improvements and borrow site development costs and a 10 

percent contingency on the land required for borrow used in the SAFCA estimate. 

3.1.3 Interior Drainage Pumping Plants 

RD 1000’s largest drainage pumping facilities, Pumping Plants 1A and 1B, and the City 

of Sacramento’s Sump 160 will need to be reconstructed to accommodate the 200-year 

project in Reach A. SAFCA’s estimate of the cost of this work reflects the design 

consultant’s opinion of probable cost based on a 30 percent design plus a 30 percent 

contingency. 

The USACE estimate for this reconstruction work is much lower than SAFCA’s estimate, 

however the basis for this difference is unclear. 

3.1.4 Lands & Damages 

A substantial amount of agricultural and rural residential land will be needed to 

accommodate the levee improvements planned for Reach A as well as the relocation of 

the Riverside Irrigation Canal in this reach. SAFCA’s estimate of the cost of this land 

reflects the range of the actual costs incurred for agricultural and rural residential land 

elsewhere in the Natomas Basin and includes a 10 percent contingency. 

SAFCA’s estimate also includes costs for lands and damages administration that 

represent about 38 percent of the value of the land to be acquired. 

The USACE estimate for lands and damages including administration is about the same 

as SAFCA’s estimate. 

8

3.1.5 Relocations 

 

 

SAFCA’s estimate includes costs for relocating about two miles of the Riverside 

Irrigation Canal, one private irrigation well, structural demolition and tree removal, and 

over 100 electrical utility poles along the landside toe of the levee. This estimate reflects 

the design consultant’s opinion of probable cost based on a 30 percent design plus a 30 

percent contingency. 

The USACE estimate for relocations in this reach is about the same as the SAFCA 

estimate. 

3.1.6 Planning Engineering & Design 

 

 

SAFCA’s estimate for planning, engineering and design costs in Reach A includes costs 

incurred through 2010 and cost projections for completing the engineering and design of 

the 200-year project features in this reach in 2011. This estimate represents 

approximately 23 percent of the estimated costs for mitigation site development, 

construction and relocation work including contingencies. 

The USACE estimate for these activities is comparable to SAFCA’s estimate, although 

the SAFCA estimate represents a higher percentage of total construction and relocation 

costs than the USACE estimate. 

3.1.7 Cultural Resources 

SAFCA’s estimate assumes that cultural resources costs will equal 2 percent of total 

construction and relocation costs. The USACE estimate does not include a reach by reach 

estimate for these costs. 

3.1.8 Construction Management 

SAFCA’s estimate for construction management costs equals approximately 15 percent 

of SAFCA’s estimated total cost for construction and relocation work including 

contingencies. This is higher than the USACE construction management estimate which 

is equal to about 8 percent of USACE’s estimated total cost for construction and 

relocation work.

3.1.9 Summary – Reach A 

When totaled, the cost estimates for each of the project accounts described above result in the USACE estimate for the NED Plan is 

about the same as the SAFCA estimate for the 200-year project in Reach A. Table 1 provides a detailed comparison of the costs of the 

SAFCA 200-year project and the USACE NED Plan in this reach.

3.2 Reach B (Sacramento River East Levee - Elverta Road to San Juan Road) 

Reach B extends for 47,800 feet along the Sacramento River east levee from Elverta Road to San 

Juan Road. SAFCA’s SREL 2 project covers 20,250 feet of levee improvement work between 

Station 264+00 and Station 466+50 including construction of a raised adjacent levee and 

installation of cutoff walls of varying depths throughout this portion of the reach. SAFCA’s 

SREL 1 and SREL 2 projects include relocation of approximately 9,475 feet of the Elkhorn 

Irrigation Canal in this reach. Construction contracts for this work were awarded in 2009 and 

2010 and the work is expected to be completed in 2011. 

SAFCA’s SREL 3 project covers 18,650 feet of levee improvement work between Station 

466+50 and Station 653+00 including construction of shallow cutoff walls, a raised adjacent 

levee and landside seepage berms of varying widths throughout this portion of the reach. This 

work has been completely designed and construction contracts are expected to be awarded early 

in 2011 

The USACE project covers the remaining 8,900 feet of this reach between Station 653+00 and 

Station 742+00. The design for this work is 90 percent complete. It includes widening the 

existing levee by 24 feet at its current height and addressing underseepage vulnerabilities 

throughout this portion of the reach through a combination of cutoff walls and seepage berms. 

The USACE phase of the project in this reach will also include reconstruction of two of RD 

1000’s interior drainage pumping facilities - Pumping Plants 3 and 5; two of Natomas Central 

Mutual Water Company’s (NCMWC) irrigation pumping facilities - the Elkhorn and Riverside 

Pumping Plants; and the upper portion of NCMWC’s Riverside Irrigation Canal. 


The 200-year project in this reach will cause significant impacts to woodland, cropland, 

and aquatic habitats. These impacts will be offset by created woodland, cropland, 

managed marsh, GGS/Drainage Canal, and SRA facilities in Reaches B and C. SAFCA’s 

estimate of the cost of these facilities reflects actual land acquisition costs; projected site 

preparation, planting and establishment costs based on contracts awarded as part of the 

SREL 2 project; and long-term management costs derived from NBHCP and CNLM 

models. This estimate includes a 5 percent contingency for land acquisition and 

mitigation site development costs. 

SAFCA’s estimate for fish and wildlife facilities in Reach B is substantially larger than 

the USACE estimate; however the basis for this difference is unclear. 


SAFCA’s estimate for levee and floodwall construction in this reach is based on the unit 

prices contained in the contracts awarded for the SREL 2 project and on projections for 

the SREL 3 project and the USACE project. The SREL 2 unit prices reflect a favorable 

construction cost environment and are significantly lower than the unit prices used to 

estimate levee and floodwall construction costs in the uncompleted portions of the 200- 

year project. 

11

The SAFCA estimate assumes that levee and seepage berm construction in Reach B will 

require approximately 3.4 million cubic yards of borrow material. This material will be 

obtained from a variety of sources including approximately 280 acres of land in the 

Fisherman’s Lake area that will be converted to compensatory cropland and managed 

marsh following borrow operations. The net cost of the borrow material that is allocable 

to the Levees and Floodwalls account is approximately $1.7 million. This sum reflects 

the cost of obtaining the right to take approximately 0.6 million cubic yards from Airport 

lands north of the terminal and the cost to acquire approximately 30 acres of land in the 

Fisherman’s Lake area which will not be converted to project mitigation. This land will 

provide approximately 0.3 million cubic yards for construction of the USACE project. 

SAFCA’s estimate for the work covered by the SREL 2 contract contains a 5 percent 

contingency for project close-out. The estimate for the SREL 3 work that is currently out 

for bid includes a 10 percent contingency. The estimate for the work to be carried out by 

USACE includes a 20 percent contingency. 

The USACE estimate for levee and floodwall construction in this reach is about 35 

percent higher than SAFCA’s estimate. Given the availability of verifiable unit price 

information for most of this work, the basis for this difference is unclear. 


RD 1000’s Pumping Plants 3 and 5 need to be reconstructed to accommodate the raised 

adjacent levee in Reach B. This work will accomplished as part of the USACE portion of 

the project in Reach B. SAFCA’s estimate for the cost of this work is based on 60 percent 

designs and reflects the design consultant’s opinion of probable cost. The estimate 

includes a 20 percent contingency. 

The USACE estimate for this reconstruction work is much higher than SAFCA’s and 



Several hundred acres of land are needed to accommodate the 200-year project footprint 

in Reach B. A substantial portion of this land is publically owned by SCAS and managed 

as part of the Airport. 

SAFCA’s estimate of the cost of most of the privately owned land reflects actual costs 

incurred through the land acquisition process, with only a small number of acres located 

in the USACE portion of the project remaining to be acquired. 

The estimate of the cost of publically owned lands is based on a preliminary appraisal 

subject to closing out SAFCA’s comprehensive agreement with SCAS on project 

activities affecting the Airport. 

The SAFCA estimate for lands and damages includes a 5 percent contingency to address 

uncertainties associated with finalizing the judicial process in pending cases, closing out 

the SCAS agreement, and completing land acquisition in the USACE portion of the 

project. 

SAFCA’s estimate also includes costs for lands and damages administration that is equal 

to 42 percent of the costs allocable to lands and damages associated with the project 

footprint and mitigation lands in this reach. This cost reflects actual administrative costs 

12

incurred to date and projections for remaining administrative activities, and includes a 10 


The USACE estimate for lands and damages including administration is more than 

double the SAFCA estimate and is nearly triple when USACE’s larger contingency is 

included. Given the availability of verifiable land values for the majority of the reach, the 

basis for this difference is unclear. 


SAFCA’s estimate of relocation costs for the SAFCA portion of the project in Reach B 

includes costs for relocating several thousand feet of the Elkhorn Irrigation Canal and 

reconstructing the Elkhorn Sedimentation Basin; relocating a small portion of the 

Riverside Irrigation Canal; relocating several private irrigation wells and pipelines; 

structural demolition and tree removal; and relocating over 200 electrical utility poles. 

This estimate covers the relocations included in the SREL 1 and SREL 2 projects and 

reflects unit prices for contracts awarded to carry out this work in 2009 and 2010 

including a 5 percent contingency. 

SAFCA’s estimate of the relocation costs for the USACE portion of the project in Reach 

B includes costs for reconstructing the Elkhorn and Riverside Pumping Plants and 

relocating the upper portion of the Riverside Irrigation Canal. This estimate is based on 

the design consultant’s opinion of probable cost and includes a 20 percent contingency. 

The USACE estimate for relocations in this reach is approximately equal to SAFCA’s. 

3.2.6 Planning Engineering and Design 

 

The SAFCA estimate for planning, engineering and design costs in Reach B reflects 

actual costs incurred through 2010 and projections of the costs required to complete the 

200-year project in this reach plus a 10 percent contingency. As discussed above, the 

costs incurred to date reflect SAFCA’s efforts to comply with evolving federal and State 

levee design standards, state and federal endangered species requirements, federal 

aviation safety standards, and federal and state cultural resource preservation 

requirements. The USACE estimate for these activities is comparable to SAFCA’s 

estimate. 


SAFCA’s estimate of cultural resources costs covers monitoring and resource recovery 

activities. The estimate reflects actual costs incurred through the 2010 construction 

season plus projected costs for the remainder of the construction effort in Reach B. 

The USACE estimate contains only a total cost for cultural resources that is not broken 

out by reach. 


SAFCA’s estimate of construction management costs in Reach B reflects actual costs 

incurred through the 2010 construction season plus projected costs for the remainder of 

the construction effort in this reach. These costs amount to 15 percent of total 

construction and relocation costs in this reach, including contingencies. 

13

The USACE estimate for construction management in Reach B is nearly three times 

higher than the SAFCA estimate. Given the availability of actual costs for this activity 

covering most of the construction work in this reach, the basis for this difference is 

unclear. 

14

3.2.9 Summary – Reach B 

When totaled, the cost estimates for each of the project accounts described above result in the USACE estimate for the NED Plan 

being approximately $76 million higher than the SAFCA estimate for the 200-year project in Reach B. The USACE estimates for 

lands and damages, levee and floodwall construction, and construction management account for the majority of this difference. Tables 

2A and 2B provide a detailed comparison of the costs of the SAFCA 200-year project and the USACE NED Plan in this reach.

3.3 Reach C (Sacramento River East Levee - Verona to Elverta Road) 

Reach C extends for 26,400 feet along the Sacramento River east levee from Verona to Elverta 

Road. SAFCA’s SREL 1 project is part of the 200-year project in this reach. This project covers 

all of the levee improvement work in this reach including construction of a raised adjacent levee, 

installation of cutoff walls of varying depths, and construction of a landside seepage berm 

between Station 187+00 and Station 232+50. The SREL 1 project also includes relocation of 

approximately 6,450 feet of the Elkhorn Irrigation Canal and several hundred feet of private 

irrigation canals. Contracts for this construction and relocation work were awarded in 2009 and 

the work was substantially completed in 2010. 

The work in this reach also includes reconstruction of RD 1000’s Pumping Plant 2 and 

NCMWC’s Pritchard Pumping Plant. Emergency repair work on Pumping Plant 2 was 

performed by SAFCA in 2008 and 2009. The reconstruction of both pumping facilities will be 

performed as part of the USACE project in 2012. 


The 200-year project in this reach will cause significant impacts to woodland, cropland, 

and aquatic habitats. These impacts will be offset by created woodland, cropland, 

managed marsh, GGS/Drainage Canal, and SRA facilities in Reaches B and C. SAFCA’s 

estimate of the cost of these facilities reflects actual land acquisition costs; projected site 

preparation, planting and establishment costs based on contracts awarded as part of the 

Phase 2 project; and long-term management costs derived from NBHCP and CNLM 

models. This estimate includes a 5 percent contingency for land acquisition and 

mitigation site development costs. 

The USACE estimate of fish and wildlife facility costs in Reach C is much smaller than 

the SAFCA estimate. The basis for this difference is unclear. 


SAFCA’s estimate for levee and floodwall construction in this reach is based on the unit 

prices contained in the contracts awarded for the SREL 1 project. As in the case of Reach 

B, these unit prices reflect a favorable construction cost environment and they are 

significantly lower than the unit prices used to estimate levee and floodwall construction 

costs in other reaches of the project. 

The SAFCA estimate assumes that levee and seepage berm construction in this reach will 

require approximately 2.7 million cubic yards of borrow material. The vast majority of 

this material will be obtained from borrow sites on SCAS land north of the Airport 

terminal. A smaller amount was obtained from the Brookfield property located at the 

corner of Reaches D and E. The cost of this borrow material is approximately $3.8 

million reflecting the cost of obtaining the right to take approximately 2.4 million cubic 

yards from the SCAS land and 0.3 million cubic yards from the Brookfield property. 

SAFCA’s estimate includes a 5 percent contingency for completion of the levee and 

floodwall work. 

The USACE estimate for this work is slightly lower than the SAFCA’s estimate. 

17


 

 

RD 1000’s Pumping Plant 2 needs to be reconstructed to accommodate the raised 

adjacent levee in this reach. The existing facility was demolished as part of an emergency 

repair effort that occurred at the outset of the NLIP. The reconstruction will occur as part 

of the USACE portion of the project. SAFCA’s estimate reflects the actual cost of the 

demolition work that was completed and the design consultant’s opinion of the probable 

value of the reconstruction work based on a 90 percent design plus a 10 percent 

contingency. 

Excluding contingencies, the USACE estimate for this demolition and reconstruction 

work is about 20 percent higher than SAFCA’s estimate. With contingencies, the USACE 

estimate is about 55 percent higher. 


Several hundred acres of land are needed to accommodate the project footprint in Reach 

C. SAFCA’s estimate of the cost of this land reflects actual costs incurred through the 

land acquisition process and includes a 5 percent contingency. 

SAFCA’s estimate also includes costs for lands and damages administration is based on 

actual costs incurred to date plus projected costs to complete the land acquisition. This 

cost reflects actual administrative costs incurred to date and includes a 5 percent 

contingency. 

Exclusive of contingencies, the USACE estimate for lands and damages including 

administration is comparable to SAFCA’s estimate. However, the USACE estimate 

includes a 37 percent contingency compared to SAFCA’s 5 percent. Given the fact that 

the land acquisition process is essentially complete, the basis for this substantial 

contingency is unclear. 


SAFCA’s estimate includes costs for relocating a portion of the Elkhorn Irrigation Canal; 

constructing several private irrigation wells and pumping plants, structural demolition 

and tree removal; and relocating approximately 100 electrical utility poles in the project 

footprint. This estimate reflects unit prices for contracts awarded to carry out this work in 

2009 and 2010 plus a 5 percent contingency. 

The estimate also includes the cost of reconstructing NCMWC’s Pritchard Pumping 

Plant, which will be carried out as part of the USACE project. This estimate reflects the 

design consultant’s opinion of the probable cost and includes a 10 percent contingency. 

Exclusive of contingencies, the USACE estimate for relocations in Reach C is 

comparable to SAFCA’s estimate. However, the USACE estimate includes a 27 percent 

contingency compared to SAFCA’s 5 to 10 percent. Given the fact that most of the 

relocation work is complete, the basis for this substantial contingency is unclear. 

3.3.6 Planning Design and Engineering 

As in the case of Reach B, SAFCA’s estimate for Reach C includes substantial costs for 

planning, engineering and design. Virtually all of these costs represent costs incurred 

through 2010 with some additional projected costs added for completion of Pumping 

Plant 2 and Pritchard Pumping plant. As discussed above, these costs reflect SAFCA’s 

18

efforts to comply with evolving federal and state levee design standards, state and federal 

endangered species requirements, federal aviation safety standards, and federal and state 

cultural resource preservation requirements. The USACE estimate for these activities is 

comparable. 


SAFCA’s estimate of cultural resources costs for this reach covers monitoring and 

resource recovery activities. The estimate reflects actual costs incurred through the 2010 

construction season and represent about 2.2 percent of total construction and relocation 

costs. 


out by reach. 


SAFCA’s estimate of construction management costs reflects actual costs incurred 

through the 2010 construction in Reach C. These costs amount to about 15 percent of 

SAFCA’s estimate of total construction and relocation costs in this reach, including 

contingencies. 

The USACE estimate for construction management in Reach C is about five times higher 

than the SAFCA estimate. Given the availability of actual costs for this activity covering 

most of the construction work in this reach, the basis for this difference is unclear. 

3.3.9 Summary – Reach C 

When totaled, the cost estimates for each of the project accounts described above result in the 

USACE estimate for the NED Plan being approximately $28 million higher than the SAFCA 

estimate for the 200-year project in Reach C. The USACE estimate for construction management 

accounts for more than the total difference of $28 million. Table 3 below provides a detailed 

comparison of the costs of the SAFCA 200-year project and the USACE NED Plan in this reach.

3.4 Reach D (Natomas Cross Canal) 

Reach D extends for 28,737 feet along the Natomas Cross Canal (NCC) south levee from Verona 

to the Pleasant Grove Creek Canal. SAFCA’s 200-year project in this reach includes raising the 

existing levee and flattening its landside slope; installing a cutoff wall along the entire length of 

the levee; reconstructing RD 1000’s Pumping Plant No. 4; relocating two irrigation and drainage 

canals and a private irrigation pump; demolishing NCMWC’s Bennett and Northern Pumping 

Plants; and constructing a closure structure at the State Route 99 crossing of the NCC. Much of 

this work has been completed through construction contracts awarded in 2007, 2008, and 2010. 

The remainder, including reconstruction of Pumping Plant No. 4 will be performed as part of the 

USACE portion of the project. 


Compensation for the impacts of the 200-year project on cropland and woodland habitats 

in Reach D is being provided primarily through construction of managed marsh in the 

Fisherman’s Lake area in Reach B. SAFCA’s estimate of the cost of these facilities 

reflects actual land acquisition costs; projected site development, planting and 

establishment costs based on engineering and landscape management consultant 

estimates; and long-term management costs derived from NBHCP and CNLM models. 

The costs for mitigation site development includes a 10 percent contingency. 

The USACE estimate does not include any costs for fish and wildlife facilities in this 

reach. This may reflect the assumption that the NED Plan does not include raising the 

NCC south levee. 


SAFCA’s estimate for levee and floodwall construction in Reach D is largely based on 

the unit prices in the contracts awarded. The Reach D levee improvements are 

substantially complete and no contingency is included for the levee improvements. These 

costs are slightly higher than the costs incurred for similar activities in Reaches B and C. 

A small amount of levee and floodwall work remains to be performed in this reach. This 

work includes the demolition of NCMWC’s Bennett and Northern Pumping Plants and 

will be performed by USACE. 

The SAFCA estimate assumes that levee construction in this reach will require 

approximately 0.9 million cubic yards of borrow material. Most of this material has been 

obtained from the Brookfield property east of State Route 99. A small amount is needed 

to support the USACE portion of the project in this reach. This material will come from 

the triangle area east of the PGCC. The cost of this borrow material is approximately $4.6 

million reflecting the cost of acquiring the Brookfield and triangle properties. 

The USACE estimate for the levee and floodwall work in Reach D is slightly lower than 

SAFCA’s estimate. 


RD 1000’s Pumping Plant No. 4 located along the NCC south levee west of State Route 

99 needs to be reconstructed to accommodate the levee improvements in this reach. The 

reconstruction will occur as part of the USACE project. SAFCA’s estimate reflects the 

21

design consultant’s opinion of the probable cost of the reconstruction work based on a 60 

percent design plus a 25 percent contingency. 

Excluding contingencies, the USACE estimate for this reconstruction work is about twice 

as a high as SAFCA’s estimate. This difference is magnified by USACE’s inclusion of a 

49 percent contingency on its estimate. 


A relatively small amount of agricultural and rural residential land is needed to 

accommodate the 200-year project footprint in Reach D. SAFCA’s estimate of the cost of 

this land reflects actual costs incurred through the land acquisition process and includes a 

5 percent contingency. 


represent about 21 percent of the value of the mitigation and project footprint land 

acquired. This cost reflects actual administrative costs incurred to date and includes a 5 


Exclusive of contingencies, the USACE estimate for lands and damages including 

administration is smaller than SAFCA’s estimate. However, the USACE estimate 

includes a much larger contingency, thus making the USACE estimate higher than 

SAFCA’s. 


SAFCA’s estimate includes costs for relocating the Vestal Drainage Canal, the Odysseus 

Irrigation Canal; and installing a closure structure on the State Route 99 overcrossing of 

the NCC. Most of this work will be carried out as part of the USACE project. The 

estimate is based on design consultant estimates and includes a 25 percent contingency. 

The USACE estimate for relocations in Reach D is approximately four times higher than 

SAFCA’s estimate. The basis for this difference is unclear. 


 

SAFCA’s estimate for planning, engineering and design costs in Reach D is based 

primarily on costs incurred through 2010 plus an allowance for engineering and design of 

the uncompleted elements of the project in this reach. This estimate includes a 10 percent 

contingency and the total planning, design, and engineering costs for reach D represents 

about 15 percent of total construction and relocation costs in this reach. The USACE 

estimate for these activities is comparable to SAFCA’s. 


SAFCA’s estimate of cultural resources costs for this reach covers monitoring and 

resource recovery activities. The estimate reflects actual costs incurred through the 2010 

construction season and represents about 2.1 percent of total construction and relocation 

costs in this reach. 


out by reach. 

22


 

 

SAFCA’s estimate of construction management costs reflects actual costs incurred 

through the 2010 construction in Reach D. These costs amount to about 15 percent of 

SAFCA’s estimate of total construction and relocation costs in this reach, including 

contingencies. 

The USACE estimate for construction management in Reach D is more than six times 

higher than the SAFCA estimate. Given the availability of actual costs for this activity 

covering most of the construction work in this reach, the basis for this difference is 

unclear.

3.4.9 Summary – Reach D 


being approximately $38 million higher than the SAFCA estimate for the 200-year project in Reach D. The USACE estimate for 

construction management accounts for more then all of this difference. Table 4 provides a detailed comparison of the costs of the 

SAFCA 200-year project and the USACE NED Plan in this reach.

3.5 Reach E (Pleasant Grove Creek Canal) 

Reach E extends for 17,394 feet along the Pleasant Grove Creek Canal (PGCC) west levee from 

the Natomas Cross Canal to Sankey Road. SAFCA’s 200-year project in this reach includes 

reconstructing the existing levee to create a wider crown and flatter landside slope; installing 

cutoff walls in several portions of the levee; installing rock protection on the waterside levee 

slope; installing a vinyl beaver exclusion cutoff wall at the waterside toe of the levee; relocating 

several private irrigation wells; relocating electrical utility poles and lines; reconstructing the 

roadway on top of the levee; raising two bridge decks crossing the PGCC; and reconstructing 

five existing drainage culverts beneath the levee. This work will be completed as part of the 

USACE project. 


The 200-year project in this reach will have significant impacts on cropland (primarily 

rice) habitat. Compensation for these impacts will be provided through construction of 

managed marsh facilities at the Brookfield site in Reach D. SAFCA’s estimate of the cost 

of these facilities includes costs for improving the NCMWC’s Chappel Ditch. The 

estimate reflects engineering and landscape design consultant estimates and long-term 

management costs derived from NBHCP models. 

SAFCA included a 10 percent contingency for both mitigation site development and 

mitigation land acquisition costs. The USACE estimate includes costs for fish and 

wildlife facilities in this reach that is approximately 30 percent higher than SAFCA’s 

estimate when contingencies are included. This is likely because this estimate includes 

costs for fish and wildlife impacts in other project reaches. 


SAFCA’s estimate for levee and floodwall construction in this reach is based on the 

design consultants estimate of probable cost. The estimate includes costs for waterside 

rock slope protection and vinyl sheet pile beaver exclusion wall installation based on a 60 

percent design and includes a 25 percent contingency. 


approximately 0.4 million cubic yards of borrow material. This material will be obtained 

from borrow sites in the Triangle area east of the PGCC. The cost of this borrow material 

is approximately $3.0 million reflecting the cost of the property that will serve as the 

source of the borrow material. The cost to acquire Triangle land for borrow includes a 10 


The USACE estimate for this work is about 50 percent higher than SAFCA’s estimate 

including contingencies. 


Approximately 87 acres of agricultural land is needed to accommodate the 200-year 

project footprint in Reach E. SAFCA’s estimate of the cost of this land reflects the range 

of the actual costs incurred for agricultural land elsewhere in the Natomas Basin and 


25


represent about 39 percent of the value of the land acquired. 

The USACE estimate for lands and damages including administration is about 4 times 

higher than SAFCA’s estimate. This likely reflects a difference in the amount of land to 

be acquired, however the basis for this difference is not clarified in the PACR. 


SAFCA’s estimate includes costs for relocating several private irrigation wells; relocating 

approximately 35 electrical utility poles and lines; raising the Howsley Road and Fifield 

Road bridges; reconstructing the roadway on top of the levee; and demolishing five 

existing drainage culverts beneath the levee. This work will be carried out as part of the 

USACE project. The estimate is based on design consultant estimates and includes a 25 


The USACE estimate for relocations in Reach E is about 20 percent lower than SAFCA’s 

estimate when contingencies are included. 


 

SAFCA’s estimate for planning, engineering and design costs in Reach E includes costs 

incurred through 2010 and cost projections for engineering and designing the 

uncompleted elements of the project in this reach. This estimate represents about 23 

percent of the estimated costs for construction and relocation work. The USACE estimate 

for these activities is comparable to SAFCA’s. 


SAFCA’s estimate of cultural resources costs for this reach covers potential monitoring 

and resource recovery activities. The estimate represents approximately 1.4 percent of 

total construction and relocation cost. 


out by reach. 


SAFCA’s estimate of construction management costs represents approximately 16 

percent of total construction and relocation costs. 

The USACE estimate for construction management in Reach E is lower than SAFCA’s 

estimate. Given the much larger USACE estimates for this activity in other project 

reaches, the basis for this difference is unclear. 

26

3.5.8 Summary – Reach E 


being approximately $35 million higher than the SAFCA estimate for the 200-year project in Reach E. The USACE estimate is higher 

than the SAFCA estimate due to the higher costs in the land and levee and floodwall accounts. Table 5 provides a detailed comparison 

of the costs of the SAFCA 200-year project and the USACE NED Plan in this reach.

3.6 Reach F (NEMDC Between Sankey Road and Elverta Road) 

Reach F extends for 24,935 feet along the Natomas East Main Drainage Canal (NEMDC) west 

levee between Sankey Road and Elverta Road. SAFCA’s 200-year project in this reach includes 

reconstructing the existing levee to create a wider crown and flatter landside slope; installing 

cutoff walls in several portions of the levee; relocating several private irrigation and drainage 

facilities; relocating electrical utility poles and lines; reconstructing the roadway on top of the 

levee; raising the Riego Road bridge deck crossing the levee; and demolishing several rural 

residential home sites and a commercial/agricultural structure in the footprint of the project. This 

work will be completed as part of the USACE project. 


The 200-year project in this reach will have significant impacts on cropland (primarily 

rice) habitat. Compensation for these impacts is being provided primarily through 

construction of managed marsh facilities on acquired lands in the Fisherman’s Lake area 

in Reach B. SAFCA’s estimate of the cost of these facilities reflects actual land costs; 

projected site development, planting and establishment costs based on engineering and 

landscape design consultant estimates; and long-term management costs derived from 

NBHCP models. The estimated land and site development costs include a 10 percent 

contingency.

account in other project reaches. 



design consultant’s opinion of probable cost based on a 30 percent design and includes a 




from borrow sites in the triangle area east of the PGCC and the Krumenacher borrow site 

along the NEMDC west levee near Elkhorn Boulevard. The cost of the borrow material is 

approximately $3.7 million reflecting the cost of acquiring the Triangle properties and the

3.7 Reach G (NEMDC from Elverta Road to the NEMDC Pump Station) 

Reach G extends for 18,930 feet along the NEMDC west levee between Elverta Road and 

SAFCA’s NEMDC Stormwater Pumping Station. SAFCA’s 200-year project in this reach 

includes reconstructing the existing levee to create a wider crown and flatter landside slope; 

installing cutoff walls in several portions of the levee; relocating several private irrigation 

facilities; relocating electrical utility poles and lines; reconstructing the roadway on top of the 

levee; raising two bridge decks crossing the levee; and demolishing several rural residential 

home sites in the footprint of the project. This work will be completed as part of the USACE 

project. 


The 200-year project in this reach will have negligible impacts on wildlife habitat, 

primarily involving low value croplands that will be mitigated through establishing native 

grasslands in the project footprint at various locations in the Basin. The estimated land 

and site development costs include a 10 percent contingency.

Boulevard. The cost of this borrow material is approximately $1.4 million reflecting the 

cost of acquiring the right to take this material. The cost to acquire the right to take this 

material for borrow includes a 10 percent contingency. 

The USACE estimate for this work is over two times higher than SAFCA’s estimate 

including contingencies. This apparently reflects differences in labor and materials costs, 

contractor mark-ups, and other cost items. 


RD 1000’s Pumping Plant No. 6 located along the NEMDC west levee north of Elkhorn 

Boulevard needs to be reconstructed to accommodate the levee improvements in this

reflects the design consultant’s opinion of the probable cost of the reconstruction work 

based on a 30 percent design and includes a 30 percent contingency. 

Excluding contingencies, the USACE estimate for this reconstruction work is about twice 

as a high as SAFCA’s estimate.

3.8 Reach H (NEMDC between NEMDC Pump Station and Northgate Blvd) 

Reach H extends for 23,700 feet along the NEMDC west levee between SAFCA’s NEMDC 

Stormwater Pumping Station and Northgate Boulevard. SAFCA’s 200-year project in this reach 

includes installing cutoff walls in several portions of the levee; constructing bank protection 

improvements; relocating several water, gas and electrical lines through the levee; relocating a 

small number of electrical utility poles and lines at the landside toe of the levee; and 

reconstructing the bicycle trail on top of the levee. This work will be completed as part of the 

USACE project. 


The 200-year project in this reach will have relatively minor impacts on various fish and 

wildlife habitats. Compensation for these impacts will be provided through construction 

of fish and wildlife facilities in Reach H. SAFCA’s estimate of the cost of these facilities 

reflects projected land acquisition; site preparation, planting and establishment costs; and 

long-term management costs derived from estimates prepared by SAFCA’s landscape 

management consultants. This land acquisition and site preparation costs include a 10

from the Krumenacher borrow site. The cost of this borrow material is approximately 

$0.3 million reflecting the cost of acquiring the right to take this material. The cost to 

acquire the right to take this material for borrow includes a 10 percent contingency. 

The USACE estimate for this work is almost three times higher than SAFCA’s estimate 

including contingencies. This likely reflects the larger project footprint assumed in the 

USACE estimate as well as differences in labor and materials costs, contractor mark-ups, 

and other cost items. 


RD 1000’s Pumping Plant 8 and the City of Sacramento’s Pumping Station 102 located 

along the NEMDC west levee in Reach H need to be reconstructed to accommodate the 

levee improvements in this reach. The reconstruction will occur as part of the USACE 

project. SAFCA’s estimate of the cost of this work reflects the design consultant’s 

opinion of the probable cost based on a 60 percent design plus a 25 percent contingency. 

The USACE estimate for this reconstruction work is slightly higher than SAFCA’s. 

Given the enlarged footprint of the NED Plan in this reach, the basis for this difference is 

unclear.

The USACE estimate for lands and damages including administration is over ten times 

higher than SAFCA’s estimate. This likely reflects the larger project footprint occupied 

by the NED Plan as well as differences in estimated land values. 


SAFCA’s estimate includes costs for relocating three gas, water and electrical utility lines 

through the levee and four electrical utility poles and lines along the landside toe of the 

levee; and reconstructing the road and bicycle trail on top of the levee. This work will be 

carried out as part of the USACE project. The estimate is based on design consultant 

estimates and includes a 25 percent contingency. 

The USACE estimate for relocations in this reach is almost ten times higher than 

SAFCA’s estimate. This is because the USACE NED Plan has a much larger footprint 

than the SAFCA 200-year project. Therefore, in addition to the relocations in the 200- 

year project, the NED Plan includes raising the El Camino Avenue bridge across the 

NEMDC; reconstructing several roadway intersections; relocating 52 more electrical 

utility poles and lines; and demolishing several residential and commercial structures in 

the footprint of the plan. The USACE estimate also includes a slightly larger 

contingency.

3.9 Reach I (American River North Levee- Northgate Blvd. to I-5) 

Reach I extends for 9,600 feet along the American River north levee from Northgate Boulevard 

to the Interstate 5 overpass near the mouth of the American River. The 30 percent design for this 

portion of the project anticipates that the landside levee slope will be flattened or otherwise 

reinforced to meet minimum embankment stability requirements. Underseepage vulnerability 

will be addressed through installation cut-walls in portions of the levee. A City of Sacramento 

interior drainage pump will be reconstructed and numerous electrical utility poles and lines along 

the landside toe of the levee will be relocated. The USACE will construct these improvements. 


The 200-year project in this reach will require removal of several dozen trees along the 

landside toe of the levee. Compensation for this loss will be provided on publically 

owned lands in the lower Dry Creek floodplain. SAFCA’s estimate of the cost of this 

compensation reflects projected land acquisition; site preparation, planting and 

establishment costs; and long-term management costs derived from estimates prepared by 

SAFCA’s landscape management consultants. The land acquisition and mitigation site 

development cost estimates include 10 percent contingencies. 

The USACE estimate does not provide a cost estimate for fish and wildlife facilities in 

Reach I.

3.10 Total Program Cost Estimate 

As indicated in Table 10, SAFCA’s estimate of the total cost of the 200-year project is $780 

million, as compared to the USACE’s estimate of the total cost of the NED Plan which is $1.112 

billion. The difference is $332 million. 

The difference between these estimates appears to reflect three tendencies in the USACE 

approach. First, USACE tends to include higher land costs by adopting conservative project 

designs and per acre land values. Second, USACE tends to escalate unit costs for borrow 

material excavation, hauling and placement and cutoff wall installation beyond the costs actually 

incurred in connection with the SAFCA project and beyond the opinions of cost prepared by 

SAFCA’s design consultants Third, USACE tends to include conservative estimates for 

particular cost categories, notably construction management. The resulting cost differences are 

magnified when the USACE’s used contingencies that were higher than those used by SAFCA. 

About 50 percent of the cost difference is attributable to the USACE’s higher cost estimates for 

improving the levees on the east side of the Natomas Basin. This difference is attributable 

primarily to USACE’s uncertainties about (1) the extent of the improvements needed along the 

NEMDC west levee in the urban area upstream of the Arden-Garden Connector crossing and (2) 

the real estate requirements of the project in the triangle area east of the PGCC. Based on these 

uncertainties, USACE has assumed a greatly expanded project footprint in these areas and 

increased their estimated construction, real estate, and relocation costs. 

SAFCA does not believe the existing footprint of the lower NEMDC west levee south of the 

NEMDC Stormwater Pumping Station will require expansion. This levee was raised and 

improved to USACE standards in the 1990s. It continues to meet minimum embankment stability 

and operation and maintenance requirements. Although it would be desirable to flatten the 

landside slope of the levee to 3H:1V and expand the space available for existing electrical utility 

lines and levee operation and maintenance activities, SAFCA believes expanding the existing 

project footprint would not be cost effective, given the extensive relocations and the value of the 

land that would need to be acquired. 

SAFCA also believes the improvements to the PGCC west levee can be constructed with 

substantially less land acquisition than proposed in the NED Plan. No more than about 200 acres 

in the triangle area is needed to provide borrow material for eastside levee improvements. For 

these reasons, SAFCA is not prepared to accept the USACE estimate of project costs along the 

east side of the Basin. 

About 5 percent of the difference between the SAFCA and USACE estimates is attributable to 

USACE’s quantity assumptions for levee construction and facility relocation costs along the 

lower reach of the Sacramento River east levee and the American River north levee. 

Almost 45 percent of the difference is related to the costs to complete work currently being 

constructed by SAFCA on the Sacramento River and the Natomas Cross Canal. Much of this 

work is already constructed, awarded, or will be awarded soon; and the primary driver for the 

cost increase is conservative construction management cost estimates and higher land cost 

estimates.

Revised Draft Fish and Wildlife Facilities Cost Estimates 

Page 1 

From 

Mike Eng, AECOM 

Date January 9, 2011 

This memorandum describes the per acre cost estimate as well as estimated total costs associated with 

the Natomas Levee Improvement Program’s (NLIP’s) fish and wildlife mitigation/compensation plan 

(Plan. The Plan includes 5 main habitat compensation types: 

 

 

 

 

 

Canal habitat, which serves primarily as mitigation for NLIP impacts to waters of the U.S. and 

Giant Garter Snake (GGS) aquatic and upland habitat, 

Woodland (corridor) and elderberry shrub habitat, which serves primarily as mitigation for NLIP 

impacts to native woodland and habitat for the Valley Elderberry Longhorn Beetle (VELB), 

Managed Marsh habitat, which serves primarily as mitigation for NLIP impacts to waters of the 

U.S. and Giant Garter Snake (GGS) aquatic and upland habitat 

Managed grassland habitat, which serves primarily as mitigation for NLIP impacts to low- to 

moderate- quality Swainson’s hawk foraging habitat 

Managed agricultural upland crops (South Sutter, portions of the Fisherman’s Lake complex), 

which serve primarily as mitigation for NLIP impacts to high - quality Swainson’s hawk foraging 

habitat. 

Each of these habitats is being created and/or preserved to compensate for the impacts of the NLIP on 

related fish and wildlife habitats in the program/project area. These impacts and compensatory habitats 

have been identified and estimated by AECOM for each segment of the NLIP in accordance with the 

linear levee reaches developed by the U.S. Army Corps of Engineers (USACE) in connection with the 

Natomas Post-Authorization Change Report/Phase 4b draft EIS/EIR [NPACR]) and other environmental 

documents prepared for the NLIP. Cost estimates for each habitat compensation type are allocated to 

the reach in which the impact requiring compensation occurred or is expected to occur. The cost 

estimates cover three categories:

Revised Draft NLIP Mitigation Construction Cost Estimates 


Page 2 

 

 

 

Land Acquisition – This category covers the cost of acquiring the land supporting each of the 

compensatory habitats. These costs have been provided by Bender Rosenthal, Inc. (BRI) and 

are based on actual costs incurred or BRI estimates. No land acquisition cost has been 

assigned to managed grasslands. This habitat type is being established on land side levee 

slopes, seepage berms and other facilities that have a primary flood control purpose. Thus, the 

land costs associated with this habitat type have been assigned to the lands and damages 

account. 

Site Development – This category covers site preparation, planting and plant establishment 

costs, including irrigation and drainage facility costs. Planting and establishment costs have 

been estimated by AECOM based on actual costs incurred and professional judgment or by 

SAFCA based on experience and actual costs incurred by the Natomas Basin Conservancy 

(TNBC). Irrigation and drainage facility costs have been provided by Mead & Hunt. 

Long-Term Management – This category covers long-term management costs for each habitat 

type. Costs for managing cropland, managed marsh and canal habitats have been estimated 

by AECOM based on economic models developed for the TNBC in connection with the 

Natomas Basin Habitat Conservation Plan (NBHCP). Costs for managing woodland and 

elderberry shrub habitat have been estimated by AECOM based on the Property Analysis 

Record (PAR) models developed by the Center for Natural Lands Management. No long-term 

management costs have been assigned to grasslands habitat. This habitat type will managed 

as part of ongoing levee maintenance. 

As described above, AECOM’s estimates of project impacts and required compensations represent 

either a “per acre” or “per linear foot” calculation based on the information contained in the various 

biological assessments and environmental impact analyses prepared in connection with the NLIP. For 

the portion of the NLIP being implemented by SAFCA, these estimates reflect either completed work in 

the field or completed plans and specifications. Estimates for the portion of the NLIP to be constructed 

by USACE are based on the final Phase 4b Biological Assessment (BA) and the NPACR/Phase 4b 

Final Environmental Impact Report/Environmental Impact Statement (EIR/EIS). 

BASIS FOR COSTS AND APPROXIMATE ACREAGES REQUIRED: 

Woodland Corridors and Managed Grasslands: Costs for the woodland corridors and managed 

grassland features are based on actual contractor costs or bids on SAFCA contracts completed or in the 

process of completion to date. The woodland corridor cost estimate is based on an extrapolated “per 

acre” cost for the Cummings/Lausevic and Phase 2 Woodland corridor projects (Contract Nos. 4029 and 

4055 respectively) that have been completed to date by SAFCA’s contractors. The managed grassland 

estimates are composed of extrapolated “per acre” costs of two distinct contracts, one for the NCC 

south levee which included both the landside and waterside of the NCC south levee and one for the 

SREL which include the installation and establishment of landside grasslands only (SAFCA Contract 

No. 4066) on the already constructed (or to be constructed) aforementioned levees. They were then 

applied to all estimates of required acres for woodland corridors and managed grasslands. 

Approximate acres required: 

Woodlands – 236 acres; This estimate is based on a roughly 3:1 (3 acres:1 acre) mitigation ratio for 

impacts to woodland habitats, as stated in the NLIP CEQA/NEPA documentation adopted by SAFCA



Page 3 

and the USACE. Impacts were estimated using GIS data (polygons) extrapolated from tree canopy 

outlines on aerial photography overlain with the NLIP design CAD drawings. 

Land acquisition costs are attributed as follows: for Reach A, an average of the Dry Creek land costs 

($10,000/acre for 28 acres) and the “in-basin” land costs ($27,000/acre for 23.2 acres) was used. All 

other reaches were based solely on an estimate of $27,000/acre cost. Long term management costs 

were assumed to be $136 per acre per year per SAFCA’s revised draft cost estimate and endowment 

costs were $3,208 per acre. 

Managed Grasslands – 645.6 acres; this estimate is based on design drawings of the flood control 

features converted to GIS polygons and used to estimate acreages. It was assumed that the landside 

and the waterside of the NCC and the Pleasant Grove Creek Canal (PGCC), and the landside of the 

SREL and the Natomas East Main Drainage Canal (NEMDC) would be restored as a managed 

grassland habitat type. 

No land acquisition costs or long-term management costs are associated with this habitat as it is 

attributed to the flood control construction costs’ estimate. 

Canals: The canal habitat cost estimate is based on a plant procurement contract issued by SAFCA to 

independent plant propagation vendors and the restoration planting contract (SAFCA Contract No. 

4067) awarded which will complete the installation of habitat features in the previously constructed and 

graded (i.e. functional for drainage systems) canal system and initial plant maintenance/establishment. 

Approximate acres required: 

Upper Canal – 23 acres (Giant Garter Snake aquatic and upland habitat) including 12.5 acres (waters 

of the US/State) 

Lower Canal – 32.8 acres (Giant Garter Snake aquatic and upland habitat) including 10.6 acres 

(waters of the US/State) 

The “approximate acreages required” estimates are based on the amount of canal (new canal, nonreplacement) 

that SAFCA is required to construct, as described in the NLIP Phases 2, 3, 4a, and 4b 

Biological Opinions (BOs) received by the USACE and SAFCA, the Phase 2 and Phase 3 DFG 2081 

permits, and the USACE Phase 2, 3a, and 3b Clean Water Act (CWA) 404 and corresponding Central 

Valley Regional Water Quality Control Board CWA 401 permits. Canal mitigation is based on the BOs’ 

and the 2081 permits’ requirement for a 1:1 (acre:acre) replacement for permanent impacts to canal 

habitats and the USACE/CV RWQCB requirement for replacement of jurisdictional waters of the 

US/State. The canal segments simultaneously (not additively) provides for Giant Garter Snake 

aquatic/upland habitat and compensation for impacts to jurisdictional waters of the US/State. 

Land acquisition costs for Reach C (the upper canal) were estimated at $5,000/acre based on 

negotiations with the Sacramento County Airport System (SCAS). Land acquisition costs for Reach B 

(the lower canal) and all other reaches were estimated at “in-basin” costs which are $27,000/acre. Longterm 

management costs have been estimated by SAFCA to be approximately $619 per acre per year by 

the NBC and $893 per acre per year by Reclamation District (RD) 1000, per the draft agreements with 

the NBC and the RD 1000 for long-term management. Primary construction (grading and excavation) 

costs were estimated at an average of $2,645,200 total or $80,646 per acre in Reach B (Lower Canal) 

and $1,038,000 total or $43,250 in Reach C (Upper Canal) in addition to a restoration construction cost 

of $3,800 per acre. Endowment costs were estimated to be $4,903 per acre.



Page 4 

Managed Marsh: The managed marsh habitat cost estimate is based on SAFCA’s discussion with the 

Natomas Basin Conservancy (TNBC) and their actual implementation costs (SAFCA 2011). This 

includes the cost of plant procurement, water control materials, maintenance through establishment 

(typically within the first 3 years after initial plantings and construction), and installation of other habitat 

features and costs per long-term management agreements between SAFCA and the TNBC. 

Approximate acres required: 219; This estimate is based on the NLIP Phases 2, 3, 4a, and 4b 

Biological Opinions (BOs) received by the USACE and SAFCA and the Phases 2, and Phase 3 DFG 

2081 permits. Managed marsh mitigation is based on the BOs’ and the 2081 permits’ requirement for a 

1:1 (acre:acre) for permanent impacts to rice and canal habitats. Overall mitigation acreages required 

are based on an estimate of total combination of aquatic and upland acreage impacts. 

Land acquisition costs varied for managed marsh habitat. For all reaches except Reach D, costs are an 

average of the costs for the TNBC Natomas Farms property ($30,000/acre for 39 acres) the AKT 

property ($35,000/acre for 37 acres), and the Sharma property ($32,000/acre for 52 acres). Per SAFCA, 

partial land acquisition costs ($445,000) for the Brookfield property are associated with this analysis, as 

the other portion of those costs are included in the flood control construction costs. For Brookfield 

(which is attributed to Reach E), an extra $1,649,000 or $17,977 per acre (for primary construction cost 

is included in the total cost to reflect the improvements to be made at the Natomas Mutual Water 

Company Chappell Ditch, which will serve the Brookfield property with surface water, thus enhancing 

water quality and ensuring long-term water delivery and supply. For all other reaches, the cost of 

primary construction for managed marsh was estimated by SAFCA at $18,400 per acre. Restoration 

cost is estimated at $15,000 per acre according to SAFCA for all managed marsh locations. Long-term 

management costs have been estimated by SAFCA, to be approximately $375 per acre per year, per 

the draft agreements with the NBC for long-term management. Endowment costs were estimated to be 

$6,480 per acre. 

Agricultural Upland Crops: The South Sutter upland crop habitat acreages are based on known 

footprints of the borrow and grading operations as provided by SAFCA and their engineering 

consultants (Mead and Hunt 2010). A firm cost estimate for the restoration of these features from their 

current post-borrow condition is not known at this time, the SAFCA planning department estimates an 

average cost of $350 per acre. 

Approximate acres required: – 236 acres. This estimate is based on the CEQA documents for Phases 

2, 3, 4a, and 4b/NPACR. The CEQA documents estimate an approximately 1:1 (acre:acre) ratio for the 

mitigation of alfalfa and irrigated grassland crops (considered high quality foraging habitat for the 

endangered Swainson’s hawk species). 

Land acquisition costs are attributed to several different properties all combined for average costs. In 

Reach C, they are attributed to the Novak property ($27,000/acre for 59 acres) and the South Sutter 

property ($20,000/acre for 31 acres), for all other reaches, costs are an average ($25,696/acre) of the 

following: the remainder of the South Sutter property ($20,000/acre for 40 acres), the Hewitt property 

($26,333/acre for 33 acres), the AKT property ($35,000/acre for 12 acres), the Sharma property 

($32,000/acre for 20 acres) and Other properties (yet be identified) ($30,000/acre for 30 acres). 

Restoration costs are estimated at $350 per acre according to SAFCA. Long-term management costs, 

have been estimated by SAFCA to be approximately $368 per acre per year, per the draft agreements 

with the NBC for long-term management. Endowment costs were estimated to be $5,328 per acre.

DISCUSSION OF COSTS – REACHES A, B, C, AND I 

Natomas Levee Improvement Program Date: 13 January 2011 

Reviewed by: 

Prepared by: 

Blake Johnson, P.E. 

Robert A. Durkee, P.E., Nick Gooding, E.I.T. 

1.0 Purpose 

In September 2010, SAFCA requested HDR Engineering to prepare cost estimates for the U.S. 

Army Corps of Engineer’s (USACE) Reaches A – C on the Sacramento River East Levee 

(SREL) and Reach I on the American River North Levee (ARNL). These estimates were for 

two levee improvement plans – one to provide a 200-year level of flood protection (SAFCA 

200-year Plan) which would meet the State Interim Levee Design standards, and the other to 

meet the FEMA 100-year flood protection requirements. The 200-year project costs were 

developed using actual construction and bid costs for the SAFCA SREL Phase 1, 1B, and 2B 

projects. The 90% Design quantities and unit costs were used for the SREL Phase 3 project 

area. For the remainder of the SREL and the ARNL reaches, quantities for constructing levee 

improvements were estimated using spreadsheets, and programmatic unit costs were applied to 

those quantities to obtain estimated construction costs. These cost estimates were submitted to 

SAFCA on 21 September 2010. 

The USACE had developed a Natomas Basin Post-Authorization Change Report (NPACR) for 

the Natomas Levee Improvement Program (NLIP) under the American River Common 

Features Project. This included a cost estimate which differed greatly from SAFCA’s expected 

program costs for the NLIP. On 14 October 2010, HDR Engineering was requested to provide 

a summary write-up comparing the SAFCA 200-year project cost estimate with the USACE 

National Economic Development (NED) project cost estimate to attempt to explain why the 

costs were different. This report was prepared to discuss those cost differences. 

2.0 Preliminary Opinion of Probable Costs 

There are significant differences in total project costs per reach between the SAFCA 200-year 

Plan and the USACE NED Plan. Since HDR does not have knowledge of all of the 

assumptions and inputs used for the USACE estimate, it is difficult to pinpoint where specific 

differences are or why they are different. 

The SAFCA estimate was prepared by HDR and considered quantities multiplied by unit price 

methodology, similar to a bidding environment. As stated earlier, unit prices used by HDR 

were programmatic rates developed by SAFCA, HDR, and other consultants for NLIP planning 

purposes. 

Sacramento Area Flood Control Agency 1 


January 13, 2011


USACE estimates were prepared by the Sacramento District Cost Engineering Branch using the 

MII cost estimating software and quantities which were provided by HDR. The quantities in 

the SAFCA and USACE estimates are not greatly different, therefore it is assumed that the 

major difference between the estimates lies in the unit prices used for estimating construction 

costs and the contingencies applied to the total costs. The unit pricing and MII cost data used 

by the USACE is not disclosed in their cost document, Appendix G of the NPACR, therefore 

HDR can not describe why unit prices used by the USACE are apparently so much greater than 

those used in the SAFCA estimate. 

Table 1 shows the various features contained in the SAFCA and the USACE projects, broken 

down by station and reach. The features for both the SAFCA 200-year Plan and the USACE 

NED Plan are the same. The only difference between the plans is the SAFCA project included 

a levee raise, through construction of an adjacent levee, to a top of levee elevation of the 200- 

year flood profile plus three feet. The USACE NED Plan did not include a levee raise, and 

only included a widened levee section at the same elevation as the existing levee. 

The cost estimates prepared for SAFCA are provided in Appendix A. Cross sections for both 

the SAFCA 200-year Plan (identified as SAFCA Locally Preferred Plan or SAFCA-LPP) and 

the USACE NED Plan through each reach are provided in Appendix B. 

For planning purposes, the USACE estimated construction of the remaining levee improvement 

features would extend through the year 2018. It is assumed the USACE applied escalation 

factors to the cost estimates to represent the time value of money in future years. They may 

have also used a different valuation of borrow area development and haul road development 

than used in the SAFCA estimate. Again, these are possible areas of difference between the 

estimates. 

It should be noted that HDR provided MII estimates of direct cost to the USACE for pumping 

plant improvements, private irrigation facility relocations, and the Riverside Canal relocation 

improvements. Direct costs are not considered to be the fully estimated cost by the USACE. 

There are multiple contractor and owner markups added to direct costs within the MII software. 

These markups were performed by the USACE and not disclosed to HDR or within the 

NPACR appendix. The following discussion by USACE Reach only pertains to Account 11, 

Levees and Floodwalls, of the USACE NED estimate. 

For the SAFCA LPP cost estimates, the costs for pumping plant improvements, private 

irrigation facility relocations, and the Riverside Canal relocation improvements were estimated 

by Mead & Hunt and not by HDR. 

Unless otherwise shown, all landside slopes for levee improvements in Reaches A, B, C and I 

were 3 horizontal to 1 vertical (3H to 1V). 



January 13, 2011


2.1 Reach C 

2.1.1 Description 

USACE Reach C extends from the northern end of the Sacramento River East Levee, at its 

confluence with the Natomas Cross Canal, to Elverta Road. USACE Reach C includes SAFCA 

Reaches 1 through 5A. This reach begins at STA. 0+00 and ends at STA. 263+00. As of the 

date of this report, most of the flood improvements have been constructed along the entire 

length of Reach C including a raised adjacent levee, cutoff walls, seepage berms, and interim 

pumping plant modifications. Costs included for the SAFCA 200-year Plan are the actual 

construction costs or bid prices for these reaches. 

2.1.2 Assumptions 

 

Since the entire length of Reach C has been constructed or is under construction, the 

construction costs for this reach were a combination of the actual costs incurred by 

SAFCA or under current contract. 

 

 

The NED Project quantities provided by HDR to the USACE assumed that a widened 

levee would be constructed on the landside of the existing levee with a top width of 24- 

feet and a landside slope of 3H to 1V. A soil-bentonite cutoff wall would be installed in 

the widened levee section and seepage berms would be constructed within the widened 

levee section for much of the Reach C. 

The SAFCA improvements through Reach C would consist of an adjacent levee 

constructed on the landside of the existing levee to an elevation above the 200-year 

water surface elevation plus 3-feet. The SAFCA improvements would consist of a 

combination of soil-bentonite cutoff walls through the adjacent levee and seepage 

berms at the landside toe. 

2.1.3 Discussion of Cost Differences 

Actual contract costs were used in preparation of the SAFCA estimate for Reach C. The 

USACE estimate for levee improvements is approximately $600,000 lower than the SAFCA 

estimate. Considering the actual construction costs have been made available to the USACE, it 

is unclear why these cost estimates are different, but may be due to the USACE not accounting 

for recent contract change orders. 

2.2 Reach B 


USACE Reach B extends from Elverta Road south along the Sacramento River East Levee to 

San Juan Road. The SREL Phase 2B and Phase 3 projects, part of SAFCA’s NLIP, are located 

within Reach B. The Phase 2B project has already begun construction and the Phase 3 project 

is at the 100% design level. USACE Reach B includes SAFCA Reaches 5B through a portion 

of Reach 15. 



January 13, 2011


The Phase 2B project extends from STA. 228+00 to STA. 468+00. The SREL Phase 3 Project 

extends from STA. 468+00 to STA. 653+00, approximately 2,000 feet south of Power Line 

Road. The remainder of the Reach B improvements extend from STA 653+00 to STA 742+60 

at San Juan Road. The improvements at the end of Reach B are to be constructed under the 

authority of the USACE. For the sake of this estimate, assumptions were made in order to 

provide an estimated construction cost for this area. 


The Phase 2B contract prices were used for a portion of the SAFCA 200-year Plan project. The 

Phase 3 project for SAFCA reflected the 90% Estimate of Probable Costs. The remainder of 

Reach B had only been designed to the 90% level at the time the SAFCA estimate was 

prepared, so those 90% costs were used for the SAFCA project. 

The Phase 2B contract prices were made available to the USACE for their estimates in Reach 

B. Quantities provided to the USACE for the Phase 3 project reflect the 60% design as this was 

the most recent data available at the time. This results in a slight difference in the quantities 

used in the SAFCA estimate and what was provided to the USACE. 

For the levee improvements located from STA 653+00 to STA 742+60 assumptions were made 

by HDR in order to provide an estimated cost of construction. Levee improvements in this are 

include no levee raise, a 24 foot levee widening section, and cutoff walls and seepage berms of 

varying sizes. The features used for cost estimating purposes were base on the most recent 

geotechnical data provided by Kleinfelder for the SAFCA project. 


Levee improvement costs in the USACE estimate differ from the SAFCA estimate by 

approximately $15.6 million. The slight difference in quantities is most likely the cause of this 

difference. 

2.3 Reach A 


USACE Reach A extends along the Sacramento River East Levee from San Juan Road south to 

the I-5 overpass over the levee and the American River. Reach A includes a portion of SAFCA 

Reach 15, Reaches 16 through 20B, and a portion of ARNL Reach 1. Reach A extends from 

STA. 742+60 to STA. 960+00. 

Included in the Reach A improvements are costs for modifications of RD 1000's Pumping 

Plants 1A and 1B as well as for City of Sacramento's Sump 160. There are also utility and 

private irrigation costs within this reach. 



January 13, 2011



The SAFCA 200-year Plan and USACE NED Plan are identical within Reach A. Project cost 

estimates were calculated by spreadsheet using the features shown in Table 1. The levee 

improvements within Reach A are based on the most recent analysis by Kleinfelder, the 

geotechnical subconsultant for the SAFCA project. The levee improvements include widening 

the existing Garden Highway an additional 24 feet, seepage berms, and cutoff walls of varying 

depths. Typical cross sections of the Reach A improvements are included in Appendix B. 

Programmatic unit prices were used to obtain estimated construction costs. Contingencies were 

applied to these estimates by SAFCA. 


The USACE estimate for Reach A is approximately $27.5 million higher than the SAFCA 

estimate. Because the features and quantities for both plans are the same the difference in cost 

is likely attributed to unit costs used by the USACE. 

2.4 Reach I 


USACE Reach I extends along the American River North Levee from the I-5 overpass to the 

lower reach of the Natomas East Main Drainage Canal (NEMDC), at a point located slightly 

East of Northgate Boulevard. The improvements would be from STA. 0+00 (SREL STA. 

960+00) to STA. 115+63. 


The Reach I improvements for both the SAFCA 200-year Plan and the USACE NED Plan are 

very similar, differing only slightly in depth of cutoff wall. The existing top of levee elevation 

is already well above the 200-year water surface profile plus 3-feet, so both plans are providing 

approximately the same level of flood protection. Construction was assumed to require leaving 

part of the levee crown open for vehicle traffic while the remaining portion of the levee is 

degraded for construction of a cutoff wall. Temporary fill would also be placed at the landside 

of the levee to achieve the necessary working platform for cutoff wall construction. Typical 

sections for Reach I are included in Appendix B. 


The Reach I USACE cost estimate is significantly higher than the SAFCA estimate despite 

only minimal differences in proposed work between the SAFCA project and USACE project. 

The USACE estimate is approximately $10.3 million higher than the SAFCA estimate. 

3.0 Conclusion 

As stated above, there are several possibilities for the differences of construction costs between 

SAFCA and the USACE including the following: 



January 13, 2011


 

 

 

 

Construction start and finish, SAFCA has completed a significant amount of 

construction compared to the USACE estimated completion timeframe of 2018 

Quantity differences 

Real Estate acquisition 

Contingencies 

The current bidding environment makes construction estimating very difficult. The MII 

cost estimating tool used by the USACE establishes labor, equipment, material, overhead 

rates, etc. Based on some of the unit prices received by current contractors for the 

SAFCA projects, it appears the contractors costs are well below established norms (i.e. it 

would appear that contractors have lowered to zeroed-out the cost of some equipment). 

The MII software would not seem reasonable if a zero dollar amount was used for 

equipment. This bidding environment may, however, not continue through the timeframe 

of the USACE project. 

The best way to compare the SAFCA project with the USACE project would be to use similar 

unit pricing along with the quantity estimates. This would provide a direct comparison of the 

flood control improvement projects proposed by both agencies. Comparison is currently made 

difficult as it is dependant on the opinion of construction cost. Unit pricing used by the 

USACE has not been provided in the NPACR appendices. It is HDR’s recommendation that a 

direct comparison of unit pricing between SAFCA and the USACE be made to determine 

where the differences are and why the costs are different.

Natomas Levee Improvement Program – Total Program Cost Estimate 

1.0 Introduction 

This technical memorandum provides an opinionn of probable construction costs for internal drainage, 

irrigation, and borrow site costs for the Natomas Levee Improvement Program (NLIP). The memo is 

organized 

following the 

U.S. Army Corps of Engineers’ (USACE) Reach Designation. For each reach, a 

brief description and total cost are included. Cost estimates presented are 

based on the 

constructionn bids 

received, if available, or are based on the Engineer’s opinion of probable construction costs using unit 

prices from 

recent contractor bids for similar work and unit prices from product suppliers. A summary 

cost 

table is included in Section 12.0. Detailed cost estimates are included in the Appendix. 

2.0 Reach A 

2.1 Levees & Floodwalls 

2.1.1 USACE Project Borrow Sites 

The borrow cost for the Reach A borrow sites is $7,334,000. The cost assumess that 1,438,000 

cubic yards (CY) of material are required 

with a unit cost of $5.10/CY. The estimate includes 

borrow site excavation, hauling to the improvements, 

and reclamation of the borrow site to a 

condition similar to the pre-project condition, but doess not include land acquisition costs. The 

borrow sites proposed for use in Reach A are described below. 

Natomas Boot 

The Natomas Boot borrow site consists of four parcels totaling 160 

acres. This proposed borrow 

area is located 

between Fisherman’s Lake and Radioo Road in Reach A:13-14. It is currently 

used 

for agricultural row crop production. It will be excavated to a depth 

of 2–4 feet and returned to 

agricultural production. It will drain from south to north into a new collector drain which will 

ultimately discharge throughh culverts into 

Fisherman’ss Lake at the northeast and northwest 

corners of the site. The potential borrow 

material yield is approximately 714,000 CY, all of which 

will be used for Reach A. 

Alleghany 

The Alleghany 

parcel is approximately 94 

acres located south of Radio Road and west of El 

Centro Road in 

Reach A:14-15. This site 

is currently agricultural land and will be reclaimed as 

such following borrow activities. It will be 

excavated to a depth of approximately 

6 feet. 

Approximately 

409,000 CY of material from this site will be used in 

Reach A.

Johnson/Huffstutler 

The Johnson/Huffstutler property is approximately 60 acres located north of Radio Road in Reach 

A:14. This proposed borrow area is currently used for agricultural row crop production. The 

western portion will be excavated to a depth of 2–4 feet and returned to agricultural land, but the 

eastern portion will be excavated to a depth of 6-8 feet and converted to marsh. Approximately 

236,000 CY of material from this site will be used in Reach A. 

2.1.2 ARNL Borrow Site 

The borrow cost for the ARNL borrow sites in Reach A is $775,000 with material from Twin 

Rivers. The cost assumes that 102,000 CY of material are required with a unit cost of $7.60/CY. 

The estimate includes borrow site excavation, hauling to the improvements, and reclamation of 

the borrow site, but does not include land acquisition costs. 

Twin Rivers 

There is approximately 124,000 CY of material stockpiled on property owned by Twin Rivers 

Unified School District, south of Elkhorn Boulevard along the Natomas East Main Drainage Canal 

(NEMDC). Approximately 102,000 CY of material from Twin Rivers could be used for the Reach 

A:1B along the American River. 

2.1.3 Structure Demolition and Tree Removal 

The total cost for the structure demolition and tree removal in Reach A is $750,000. This cost is 

based on the assumption that there are a number of structures on the landside of the levee that 

will be impacted by Reach A improvements. However, the levee design for this reach is 

preliminary and it is unclear what the full extent of the required demolition will be. 

In general, the structure demolition and tree removal includes the removal of structures and 

cutting trees to one to three feet above ground within the levee footprint throughout Reach A. 

The work includes, but is not limited to, demolition and removal of structures, foundations, 

walkways and patios, concrete block wall, lead paint abatement, asbestos abatement, removal of 

utility services to structures, installation of pipe gate, removal of septic system, well 

abandonment, tree removal, and cleanup of the site. 

2.2 Internal Drainage and Pumping Plants 

2.2.1 RD 1000 Pumping Plant 1A 

The cost for Reclamation District No. 1000's (RD 1000) Pumping Plant No. 1A work is 

$4,725,000. The cost is from the Engineer’s opinion of probable construction costs using unit 

prices from recent contractor bids for similar work and unit prices from product suppliers. 

Pumping Plant No. 1A is located along Garden Highway approximately one mile west of the 

Interstate 5 (I-5) crossing of the American River. Modifications will be required to accommodate 

the levee improvements. Work includes, but is not limited to, the replacement of the existing box 

culverts; flap gates; sluice gates; construction of a new outfall; demolition and reconstruction of 

the RD 1000 office, which sits atop the existing box culvert; demolition of existing concrete 

culverts, and electrical work. 

2.2.2 RD 1000 Pumping Plant 1B 

The cost for RD 1000’s Pumping Plant No. 1B work is $1,839,000. The cost is from the 

Engineer’s opinion of probable construction costs using unit prices from recent contractor bids for 

similar work and unit prices from product suppliers. 

Pumping Plant No. 1B consists of six pumps, a control-room building, and associated 

infrastructure for the pumping plant. It is located immediately adjacent to the landside levee toe 

in Reach A:19B, next to Plant 1A. Each pump for Pumping Plant No. 1B connects to a buried 

discharge pipe that runs across the existing levee to an outfall structure on the east bank of the

S:\19415-00\08001\TECH\CostEst\NLIP Program Cost Table\Total Program Cost Estimate Dec 2010\cost estimate descriptions rev011311.docx

Sacramento River. There are a total of six 48-inch diameter pipes. Six air/siphon release valves, 

one for each pipe, are located close to the crown of the levee in a vault on the waterside of the 

levee. A metering vault is located on the landside of the levee. 

The pumping plant modifications will include raising and replacing the discharge pipes that extend 

from Pumping Plant No. 1B across the levee within the confines of the planned levee construction 

to tie into the existing discharge pipes on the waterside. The air/siphon release valves will be 

replaced and shutoff valves will be added. The valves will be constructed in a new concrete vault 

in the waterside shoulder of the levee. The metering vault along with the plant access ramp may 

also be replaced or relocated. The pumps and motors will also be replaced and/or upgraded to 

account for the higher head associated with the raised discharge pipes. To facilitate raising of the 

pump discharge pipes, Garden Highway will require a local raise of several feet in grade over the 

pipes, which will require partial regrading of the waterside slope for the length of the raised 

Garden Highway. 

2.2.3 City Sump 160 

The cost for City Sump 160 work is $2,881,000. The cost is from the Engineer’s opinion of 

probable construction costs using unit prices from recent contractor bids for similar work and unit 

prices from product suppliers. 

City Sump 160 is located along Reach A:19B of the Sacramento River east levee. A 90-inch 

diameter storm drain carries stormwater drainage from adjacent properties to the pump station. A 

chain link fence with slats and barbed wire is located approximately 30 feet from the landside toe 

of the levee and, combined with a concrete block wall, surrounds the pump station. Five pumps, 

an equipment building, an above ground diesel fuel storage tank, and electrical transformers are 

located behind the fence. Each pump for City Sump 160 connects to a buried steel discharge 

pipe that runs across the existing levee to an outfall structure on the Sacramento River. There 

are a total of five pipes, including two 54-inch pipes, two 42-inch pipes, and one 12-inch pipe. 

Five air/siphon release valves, one for each pipe, are located on the landside of the levee near 

the top. A concrete pipe support wall is located approximately 100 feet from the outfall on the 

waterside of the levee. 

The pumping plant modifications will include raising the discharge pipes that extend from City 

Sump 160 across the levee to tie into the existing discharge pipes on the waterside. The 

air/siphon release valves will be replaced and shutoff valves will be added. The valves will be 

constructed in a concrete vault in the waterside shoulder of the levee. If necessary, the concrete 

pipe support wall will be removed and replaced. An upgrade to the pumps and diesel engines for 

City Sump 160 will likely be required to provide the increased horsepower needed to pump 

drainage water through the raised pipes. 

To facilitate raising the pump discharge pipes, Garden Highway will require a local raise in grade 

over the pipes, which will require partial regrading of the waterside slope for the raised Garden 

Highway. The pipe raise will require a new outfall to comply with the USACE design guidelines 

for siphon recovery, which will limit the distance from the top of the apex of the pipe to the top of 

the outlet pipe. 


2.3.1 NCMWC Riverside Canal and Riverside Pipeline 

The total cost for the Natomas Central Mutual Water Company (NCMWC) Riverside Canal and 

Riverside Pipeline in Reach A is $4,312,500. The cost is from the Engineer’s opinion of probable 

construction costs using unit prices from recent contractor bids for similar work and unit prices 

from product suppliers. 

3 


Riverside Canal will extend from San Juan Road to Bryte Bend Road, a canal length of 

approximately 9,500 feet. The relocated Riverside Canal will be sited as close as possible to the 

toe of the new levee and seepage berm footprint to the extent feasible. Beginning one-half to 

three-quarters of a mile south of San Juan Road southward to Interstate 80 (I-80), approximately 

25 residences are located along the landside toe of the levee. To avoid removing a substantial 

number of the residential and agricultural structures on these private properties, the Riverside 

Canal alignment will follow the eastern property line of these parcels, veering farther east in 

Reach A:16. The final alignment will also aim to minimize conflicts with large groves of existing 

trees and other site-specific constraints that are identified during final design. Based on these 

site-specific factors and the variation of the proposed seepage remediation methods in different 

reaches, the alignment will be only roughly parallel to the projected levee toe. 

The canal right-of-way will be roughly 155 feet wide, including a landside operation and 

maintenance corridor and embankments on each side of the channel. The bottom width of the 

canal will range from about 8 feet to 10 feet wide. To provide for stable banks, the side slopes of 

the canals will be 3H:1V or flatter. The invert and side slopes of the canal will likely be lined with 

concrete for vegetation control and to allow for easier maintenance. The top of the embankments 

will be about 5.5 feet above the bottom of the channel, and about 9.5 feet above existing grade, 

with top widths of approximately 15 feet. Patrol roads will be constructed on the top of the 

embankments. 

In addition to the open canal, an approximately 5,900-foot-long, 30-inch diameter solid wall HDPE 

pipeline will be constructed immediately east of the levee footprint in Reaches A:15 to 18B. 

Alternatively, the pipeline could be constructed within the proposed seepage berm or a raised 

operation and maintenance corridor. The beginning of the pipeline will be roughly one-half mile 

south of San Juan Road in Reach A:15, where the open channel section of the Riverside Canal 

veers eastward away from the levee toe, continuing southward to I-80. A 20-foot-wide permanent 

right-of-way will need to be obtained to construct the pipeline and provide for access and 

maintenance following construction. The pipeline will be buried with at least two feet of cover. 

Turnouts will be provided along the pipeline to serve each of the parcels adjacent landside. The 

pipeline will also include several precast inlet/outlet structures at the road crossings and an outlet 

structure at the southern end. 

2.3.2 Bryte Bend Well Relocation 

The total cost for the Bryte Bend Well Relocation in Reach A is $302,700. The cost is from the 


similar work. 

There is one active and one inactive private well along the Sacramento River East Levee at the 

southeast end of the Riverside Canal (Reach A:18), both of which will be disrupted by the 

proposed levee improvements and will be abandoned. The active well will be relocated. This well 

discharges directly to the existing Riverside Canal for irrigation service to the adjacent fields for 

agricultural use. The water well will be relocated outside of the flood control footprint and sited at 

least 100 feet off of the adjacent levee toe. 

3.0 Reach B 


3.1.1 SREL 2A Borrow Site 

The borrow cost for SREL 2A borrow sites is $214,000 with material from the following sites. The 

cost for the borrow site work is from the contractor bid dated December 1, 2009, for SAFCA

3.1.2 SREL 2B Borrow Sites 

The borrow cost for SREL 2B borrow sites in Reach B is $3,940,000 with material from the 

following sites. The cost for the borrow site work is from the contractor bid for SAFCA Contract 

4046 dated April 2, 2010. The estimate includes borrow site excavation, hauling to the 

improvements, and reclamation of the borrow site to its agricultural use, but does not include land 

acquisition costs. 

Airport North Site 2 

Airport North Site 2 is approximately 120 acres located south of Pritchard Lake Road, east of the 

Airport Pritchard Lake Mitigation Site, north of the Central Main Flume, and west of Powerline 

Road. The eastern side of the site (51 acres) will be used in Reach B, while the western side will 

be used for Reach C. Airport North Site 2 will be finish graded to a standard irrigation slope to be 

reclaimed as grassland. The site will be sloped to drain to three east west drainage swales that 

flow into an existing ditch towards the west. Approximately 523,000 CY of borrow material will 

come from the east side of Airport North Site 2 for use in Reach B. 

Airport North Site 2A 

Airport North Site 2A is approximately 33 acres and is located immediately south of Airport North 

Site 2 and north of the Central Main Canal. Airport North Site 2A will be finish graded to a 

standard irrigation slope to be reclaimed as grassland. Airport North Site 2A is sloped towards 

one east-west field drains that flows to the northwest corner of the site and connects into the 

Airport North Site 2 drainage. Approximately 82,000 CY of material will be used from this site for 

Reach B. 

South Sutter 

The portion of the South Sutter site used as a source for borrow is approximately 74 acres and is 

located north of Elkhorn Boulevard in Reach B:8. A portion of the site will be used for SREL 2A 

and the remaining will be used for SREL 2B as described above. South Sutter will be finish 

graded to a standard irrigation slope to be reclaimed as agricultural land. The site generally 

slopes to the southeast to drain into the Walnut Road West Ditch. Approximately 426,000CY of 

material will be available from this site for Reach B. 

3.1.3 SREL 3 Borrow Sites 

The borrow cost for SREL 3 borrow sites is $10,057,000 with material from the following sites. 

The cost is from the Engineer’s opinion of probable construction costs using unit prices from 

recent contractor bids for similar work. The estimate includes borrow site excavation, hauling to 

the improvements, and reclamation of the borrow site, but does not include land acquisition costs. 

Sharma 

The portion of the Sharma borrow site used as a source for borrow is approximately 72 acres and 

is located north of the Plant 3 Intake Channel in Reach B:13. The western portion of Sharma will 

be reclaimed as grassland and the eastern portion will be reclaimed as a managed marsh with a 

series of open water channels, marsh, and upland areas. Approximately 884,000 CY of material 

will be available from this site for Reach B. 

AKT 

The portion of the AKT borrow site used as a source for borrow is approximately 49 acres and is 

located south of the Plant 3 Intake Channel in Reach B:13. The western portion of AKT will be 

reclaimed as grassland and the eastern portion will be reclaimed as a managed marsh with a 

5 


series of open water channels, marsh, and upland areas. Approximately 602,000 CY of material 

will be available from this site for Reach B. 

Natomas Farms Preserve 

The portion of the Natomas Farms Preserve borrow site used as a source for borrow is 

approximately 40 acres and is located north of the Sharma site in Reach B:12A-12B. The upland 

portion of the Natomas Farms Preserve will be reclaimed as a managed marsh with a series of 

open water channels, marsh, and upland areas and will be connected to the adjacent Natomas 

Farms marsh area. Approximately 350,000 CY of material will be available from this site for 

Reach B. 

RD 1000 Access Road and borrow 

The RD 1000 access road and borrow site will be constructed along the western edge of 

Fisherman’s Lake from the northeast corner of the TNBC Natomas Farms Preserve to the 

Pumping Plant No. 3 Intake Channel. The access road and borrow site will be approximately 

3,000 feet long and vary from approximately 120 to 180 feet in width. The borrow site will share 

an all-weather access road with the adjacent constructed marsh. It will also consist of a lower 

access road, a tule bench, and a deep channel. The excavation of the RD 1000 access road and 

borrow site will generate up to 120,000 CY of material for Reach B. 

Recirculation Ditch 

A recirculation ditch will be constructed from the eastern end of the TNBC supply ditch on the 

Natomas Farms Preserve to the West Drainage Canal. The ditch will enhance the circulation of 

water within the Fisherman’s Lake area of the Natomas Basin canal system. The ditch will start 

at the southwestern edge of the marsh on the Natomas Farms Preserve, head north along the 

eastern edge of the Souza Preserve, head east along Del Paso Road, and head north between 

the Rosa Central and Rosa East Preserves to the West Drainage Canal. The ditch will be 

approximately 6,300 feet long, 5-6 feet deep with a 5-foot bottom width and 3H:1V side slopes. 

Additionally, a drainage ditch will be constructed parallel to and west of a portion of the 

recirculation ditch from the middle of the Natomas Farms Preserve to the southwest corner of the 

Rosa East Preserve. The ditch will be approximately 2,400 feet long, 6-8 feet deep with a 5-foot 

wide bottom and 3H:1V side slopes. A 12-foot wide access road will be constructed along the 

east side of the recirculation ditch and an 18-foot wide access road will be constructed along the 

west side of the recirculation ditch, except through the Rosa Preserves, where it will be 12 feet 

wide. The excavation of the recirculation ditch will generate up to 16,000 CY of material for 

Reach B. 

3.1.4 USACE Project Borrow Site 

The borrow cost for the Reach B borrow sites is $1,091,000 with material from the 

Johnson/Huffstutler property. The cost assumes that 248,000 cubic yards (CY) of material are 

required with a unit cost of $4.40/CY. The estimate includes borrow site excavation, hauling to 


The borrow sites proposed for use in Reach B are described below. 

Johnson/Huffstutler 

The portion of Johnson/Huffstutler property used as a borrow site is approximately 60 acres 

located north of Radio Road in Reach A:14. This proposed borrow area is currently used for 

agricultural row crop production. The western portion will be excavated to a depth of 2–4 feet and 

returned to agricultural land, but the eastern portion will be excavated to a depth of 6-8 feet and 

converted to marsh. Approximately 248,000 CY of material from this site will be used in Reach B. 


The total cost for the structure demolition and tree removal in Reach B is $857,900. The cost is 

from construction costs for SAFCA Contract 4020 incurred through Change Order No. 4 dated 

January 5, the contractor bid for SAFCA Contract 4047 and Contract 4044 dated December 1, 

2009, and the bid for SAFCA Contract 4069 dated September 7, 2010. 

6

foot-long cutoff wall in the levee centered on the abandoned sump. 

The levee section adjacent to the sump was degraded to elevation 12 +/- for a length of 

approximately 140 linear feet. With side slopes of 1.5H to 1V the top of the excavation spanned 

approximately 230 feet along the levee centerline. The culvert pipe will be removed via a local 

excavation within the bench area at elevation 12. Total excavation volume is approximately 

24,000 CY. Prior to excavation, approximately 200 linear feet of 60-foot long steel sheetpiles 

were driven into the ground at the limits of excavation on the waterside of the levee. The 

sheetpiles that are proposed to be installed on the waterside of the levee can be removed after 

construction of the cutoff wall. 

A 600-foot long, 110-foot sheetpile wall will be constructed within the Sacramento River East 

Levee extending 300 feet on each side of the abandoned pump sump. Approximately 800 linear 

14 


feet of levee crown will be removed up to 5 feet deep to provide a minimum width of 30 feet for

the levee to the Elkhorn Canal the pipe is 72-inch with a 60-inch grouted liner, which transitions 

into a 6–foot by 6-foot box culvert landside of the levee. Permanent replacement pipes will be 

two 36-inch diameter pipes and one 30-inch pipe continuous from the pumps through the levee to 

the canal outfall. 

The existing pumping plant superstructure is a timber structure with a pump platform and bridge 

out into the river channel. The pipes are hung under the pumping plant platform over the water 

such that replacement will require working over the water. The pumps will be removed and 

replaced utilizing cranes working from the riverbank or from barges. Modifications to the 

Pritchard Pumping Plant timber superstructure will be required to provide stability during 

construction and adequate support for the new equipment. The deck supports, crossbeams, 

bracing and flooring of the platform will be replaced or retrofitted, working above the water. 

Additionally, concrete jackets will be installed around the existing piers in the water or the piles 

will be replaced to provide additional support for the structure improvements and new equipment. 

The electrical service for this facility is located on the landside within the levee footprint. 

Sacramento Municipal Utility District (SMUD) equipment will be relocated to the waterside of the 

levee and placed on a new pad constructed at an elevation at least 1 foot above the 200-year 

water surface elevation. The pad will be constructed on the waterside bench at the shoulder of 

existing levee and will require the placement of approximately 70 cubic yards of fill and 7 cubic 

yards of concrete. 

4.3.2 North Lauppe Pumping Plant and Cummings Pumping Plant 

The total cost for the North Lauppe Pumping Plant and Cummings Pumping Plant is $381,500. 

The cost for the work is from the contractor bid for SAFCA Contract 4056dated February 4, 2010. 

North Lauppe 

At the North Lauppe Pumping Plant site, located in Reach C:2, the existing pump will be 

refurbished. The existing pump is set back into the river bank with a steel sheetpile retaining 

15 


wall. The existing pump platform with a wooden deck and steel framing is supported off of the 

existing sheetpile wall. The existing platform structure will be improved with a new steel grating 

and handrail anchored to the existing support rails. No pile driving will be required at this site. 

The existing pump will be rebuilt with a new bowl and bell at the pump inlet. Due to uncertainties 

in subsurface conditions around the existing pump inlet and the high likelihood of significant silt 

buildup, it is anticipated that up to 7.5 CY of dredging or hand excavation around the inlet will be 

required for pump installation. The excavation acts as the clearance zone around the inlet 

impeller and will need to be maintained for proper inlet function. A 4-foot by 4-foot concrete slab 

will be constructed to support a new steel ladder at the east end of the new platform. 

Cummings 

At the Cummings Pumping Plant site, located in Reach C:1, the existing pump and discharge 

pipe will be refurbished. To provide crane access to the site, some trimming of the overhanging 

tree canopy will likely be required. The existing slant pump column is supported by a single 

concrete block that has been placed on the bank near the summer waterline (approximately 13.5- 

foot elevation contour). The existing concrete block support will be replaced at approximately the 

same location with a new steel pile support frame, consisting two new steel piles placed at 

approximately six feet either side of the pump column, with an above ground steel cross beam 

support. A second steel support frame will be constructed 15 feet up the bank. A portion of the 

existing concrete block supporting the pipeline may be removed and disposed offsite to 

accommodate the new support frame. The four new steel pilings will be driven into firm substrate 

approximately 20 feet deep. The existing pump bowl and bell at the pump suction inlet will be 

replaced with an improved pump bowl. Due to uncertainties in subsurface conditions around 

existing pump inlet and the high likelihood of significant silt buildup, it is anticipated that up to 15 

CY of dredging or hand excavation around the inlet will be required for pump installation. At the 

top of the bank the existing platform structure and wood decking will remain and be improved. 

Improvements include installation of a new handrail and ladder and construction of an 

approximately 4-foot by 4-foot concrete slab to support the new ladder. 

4.3.3 South Lauppe Pumping Plant 

The total cost for the South Lauppe Pumping Plant is $260,700. The cost is from the Engineer’s 



Work at the South Lauppe Pumping Plant site will be constructed in two phases to accommodate 

the construction of the USACE’s bank stabilization project (Sacramento Bank Protection Project, 

River Mile 77.2). To accommodate the USACE bank stabilization work, the existing vertical pump 

will be replaced with a new slant pump (pump column aligned with slope of bank) installed over 

the bank protection. Phase 1 includes demolition, footing reinforcement, and pile driving work. 

Phase 2 will include reconstruction of the pump platform and installing the new pump and 

electrical system as described below. 

South Lauppe Pumping Plant work includes replacement of the existing platform and stairs with a 

new steel operating deck, handrail, bar grating, and stairway. It also includes the installation of a 

new slant pump and motor supported by the existing vertical frame and new pipe piles, and 

connection to the existing pipeline. The existing concrete abutment at the river end of the 

platform will remain with some fortification. The existing steel frame at that location will be 

removed, fortified, and replaced to support the new pump. Work includes the removal and 

replacement of an existing concrete footing at the land end of the platform with new concrete 

piers. The steel frame at this location will be removed, refurbished, and replaced. Existing 

platform vertical frames will be repainted while in storage between initial removal and installation 

of the new platform. Work will also include the placement of additional timber pile “dolphins” to 

protect the slant pump column from floating debris. A new electrical service panel and conduit 

will be added approximately 16 feet to the land side of the existing service drop.

The Central Main Canal will be relocated about 1,250 feet to the north. The new canal alignment 

would begin near the transition from the existing concrete flume to the earthen canal section. 

From there, the alignment would go east between Airport North Borrow Sites 2 and 2A and cross 

Powerline Road to intersect the canal on the east side of the road at the start of the No. 3 Canal. 

A new culvert and check structure would be installed at Powerline Road. In addition, a section of 

the canal on the east side of Powerline Road from the existing culvert crossing to the No. 3 

Canal, about 1,300 feet in length, may need to be widened to accommodate a higher flowrate 

from the new culvert crossing southward to the 60’s pumps. 

The new Central Main Canal will have a 10-foot bottom width, a concrete-lined interior with 

2H:1Vside slopes, a 12-foot-wide access road on each embankment, 3H:1V exterior side slopes, 

and two 20-foot-wide field roads on each side of the canal. The canal is sized to carry a

RD 1001 

The borrow site for the initial improvements to the NCC south levee is a site owned by RD1001 

about five miles northeast of the Natomas Basin along Pacific Avenue, just east of the RD1001 

borrow site and was used for SAFCA’s 2007 NCC South Levee Phase 1 Improvements project 

under Contract 3947. 

Brookfield 

The Brookfield property was originally a 348-acre property located between Howsley Road and 

Fifield Road, west of the PGCC west levee. The property has historically been in rice cultivation. 

A portion of the western half of the site (205 acres) was purchased by SAFCA and excavated to a 

depth of up to approximately six feet. Some material was used for Reach C with the remainder 

used in Reach D. Approximately 838,000 CY of borrow material will come from Brookfield for 

Reach D. 

Grading of the site was performed at a slope to allow the water to flow back to the drainage 

canals running along the west and south side of the property. The water from the eastern fields 

will be drained into a canal along the west side of the pasture land and into the southern drainage 

canal. Onsite drainage and irrigation canals were constructed. The western portion of the site 

was graded and returned to rice cultivation. Additional irrigation and drainage improvements 

offsite will be required to improved irrigation and drainage for long-term rice production as 

described in section 6.2.1. 

5.1.2 NCC Future Borrow Site 

The borrow cost for the NCC 3 Borrow in Reach D is $474,000 with material from the Triangle 

Property. The cost assumes that 93,000 CY of material with a unit cost of $5.10/CY. The 



Triangle Properties 

The Triangle Properties Borrow Area is located to the northeast of the Natomas Basin on the east 

side of the PGCC. It is bordered on the east by the Union Pacific Railroad. Farmland will be 

excavated to a depth of up to six feet and either reclaimed for rice cultivation or converted to 

detention basins to store PGCC overflow in the event that the PGCC culverts are removed. No 

demolition of residences or other non-agricultural uses will occur as part of borrow excavation. 

Excavation sites within the Triangle Properties Borrow Area will be set back at least 100 feet from 

existing roads, utilities, or irrigation ditches. The bridges for Howsley, Fifield, Keys, and Sankey 

Roads will be used as haul routes to bring the borrow material over the PGCC into the Natomas 

Basin for the construction of the PGCC and north NEMDC. Alternatively, temporary crossings of 

18 


the PGCC could be constructed with culverts or bridges over the low-flow channel, to provide for 

off-road hauling. Approximately 93,000 CY from the Barosso property within the Triangle 

Properties will be used for Reach D. 


The total cost for the structure demolition and tree removal in Reach D is $63,300. The cost is

electrical, control, and monitoring equipment. The pumps, electrical equipment, maintenance 

platform, and pump deck will remain elevated above the Natomas Basin’s interior 100-year flood 

elevation. Related infrastructure, such as access roads and utilities that serve Pumping Plant No. 

4 and are located within the levee footprint, will be relocated outside the footprint. An upgrade to 

the pumps and the electrical service for Pumping Plant No. 4 is required to provide the increased 

horsepower needed. The plant and the intake channel will also require modifications to mitigate 

levee underseepage potential. The remediation work will include stabilization of the intake 

channel. The channel remediation will extend 300–400 feet upstream of the pumping plant 

entrance and may include a combination of installing relief wells, flattening the slopes of the 

channel banks, and lining the channel with a gravel or geotextile filter layer covered with rock.

Pumping Plant No. 6 is located along the NEMDC, approximately three-quarters of a mile north of 

Elkhorn Boulevard in Reach G. The pumping plant modifications will include raising and 

replacing the discharge pipes (one 42-inch pipe, two 36-inch pipes, and one 30-inch diameter 

pipe) that extend from Pumping Plant No. 6 across the levee to tie into the existing discharge 

pipes within the waterside of the levee. The four air/siphon release valves will be replaced and 

shutoff valves will be added. The valves will be constructed in a concrete vault in the waterside 

shoulder of the levee. An upgrade to and/or replacement of the pumps, motors, and the electrical 

service including a new electrical building for Pumping Plant No. 6 will be required to provide the 

increased horsepower needed to pump over the levee. Use of new pumps could require the 

excavation of a deeper sump, which may require some associated modifications to the landside 

intake channel. 

To facilitate raising the pump discharge pipes, East Levee Road will require a local raise in grade 

over the pipes, which will require partial regrading of the waterside slope for the length of the 

raised East Levee Road. The levee will transition upstream and downstream of this site from an 

adjacent levee to a raise of the existing levee in place. At this site, the levee will be degraded 

and reconstructed with engineered fill. The pipe raise may require a new outfall to comply with 

the USACE design guidelines for siphon recovery, which limit the distance from the top of the 

apex of the pipe to the top of the outlet pipe. 



The total cost for the Private Irrigation Relocation work in Reach G is $1,214,200. The cost is 



Numerous private irrigation facilities along the NEMDC will be disrupted by the proposed levee

pumping plant modifications will include raising and replacing the discharge pipes (including six 

54-inch pipes, three 36-inch pipes, and one 60-inch diameter pipe) that extend from Pumping 

Plant No. 8 across the levee to tie into the existing discharge pipes within the waterside bench. 

The air/siphon release valves will be replaced and shutoff valves will be added. The valves will 

be constructed in a concrete vault in the waterside shoulder of the levee. An upgrade to and/or 

replacement of the nine pumps, motors, and the electrical service including a new electrical 

building for Pumping Plant No. 8 will be required to provide the increased horsepower needed to 

pump over the levee. Use of new pumps could require the excavation of a deeper sump, which 

may require some associated modifications to the landside intake channel. 

To facilitate raising of the pump discharge pipes, the existing bike trail will require a local raise in 

grade over the pipes, which will require partial regrading of the waterside slope for the length of 

the raised bike trail. The pipe raise may require a new outfall to comply with the USACE design 

guidelines for siphon recovery, which limit the distance from the top of the apex of the pipe to the 

top of the outlet pipe.

City Sump 102 is located along the NEMDC west levee adjacent to Gardenland Park north of 

Bowman Avenue. A 60-inch diameter storm drain carries stormwater drainage from adjacent 

properties to the pump station. A chain link fence with slats and barbed wire is located at the 

landside toe of the levee and surrounds the pump station. The pumping plant modifications will 

include replacing the four discharge pipes that extend from City Sump 102 across the levee to tie 

into the existing discharge pipes (three 36-inch pipes and one 12-inch pipe) within the waterside 

bench. The four air/siphon release valves will be replaced and shutoff valves will be added. The 

valves will be constructed in a concrete vault in the waterside shoulder of the levee. An upgrade 

to the four pumps, motors, and the electrical service for City Sump 102 will be required to provide 

the increased horsepower needed to pump through the raised pipes. To facilitate raising of the 

24 


pump discharge pipes, the bike trail will require a local raise in grade over the pipes, which will 

require partial regrading of the waterside slope for the length of the raised bike trail. The pipe 

raise may require a new outfall to comply with the USACE siphon recovery limits criteria, which 

limit the distance from the top of the apex of the pipe to the top of the outlet pipe.

pump station. A chain link fence with slats and barbed wire is located at the landside toe of the 

levee and surrounds the pump station. The pumping plant modifications will include replacing the 

discharge pipes two 20-inch pipes and one 12-inch pipe) that extend from City Sump 58 across 

the levee to tie into the existing discharge pipes on the waterside. The cutoff structure will be 

removed. The three air/siphon release valves will be replaced and shutoff valves will be added. 

The valves will be constructed in a concrete vault in the waterside shoulder of the levee. An 

25 


upgrade to the three pumps, motors, and the electrical service for City Sump 58 will be required 

to provide the increased horsepower needed to pump through the raised pipes. 

To facilitate raising the pump discharge pipes, Garden Highway will require a local raise in grade 

over the pipes, which will require partial regrading of the waterside slope for the length of the 

raised Garden Highway. The pipe raise may require a new outfall to comply with the USACE 

design guidelines for siphon recovery, which limit the distance from the top of the apex of the pipe 

to the top of the outlet pipe. 

11.0 All Reaches 

11.1 Irrigation and Drainage Improvements for Mitigation 

11.1.1 Fisherman’s Lake Irrigation and Drainage 

The total cost for the Fisherman’s Lake irrigation and drainage improvements is $2,208,000. The 

cost is from the Engineer’s opinion of probable construction costs using unit prices from recent 


Several borrow sites identified for material to be used Reaches A and B will be reclaimed as 

managed marsh, which satisfies mitigation requirements for the NLIP. Several irrigation and 

drainage features will be constructed to support the managed marsh hydrology. These irrigation 

and drainage improvements include piping, culverts, flashboard risers, fencing, and gates to 

facilitate the long-term operation and maintenance of the managed marsh. 

11.1.2 Giant Garter Snake Drainage Canal – Reach B 

The total cost for the Giant Garter Snake Drainage Canal (GGS/Drainage Canal) in Reach B is 

$2,645,200 divided among the construction components listed below. The cost is from the 

contractor bids for SAFCA Contracts 4032 and 4046 dated July 2, 2009 and April 2, 2010, 

respectively. 

SREL 1B 

The GGS/Drainage Canal construction in Reach B under SREL 1B consists of 4,400 feet of canal 

from Elverta Road and terminating in a field east of the Elkhorn Sedimentation Basin. The 

GGS/Drainage Canal will be constructed parallel to the Elkhorn Irrigation Canal and material 

excavated to construct the GGS/Drainage Canal may be used to construct the embankments for 

Elkhorn Irrigation Canal. Two concrete arch culverts will be installed at points along the 

GGS/Drainage Canal. The two culverts are approximately 162 feet and 52 feet in length, and 

facilitate one crossing of the Elkhorn Irrigation Canal and one crossing of the Delta Road Ditch 

respectively. Two check structures shall be constructed along the length of the canal. 

SREL 2B 

The Giant Garter Snake/Drainage Canal work in Reach B under SREL 2B consists of 

approximately 13,000 linear feet of excavated ditch from a field east of the Elkhorn Sedimentation 

Basin, continuing east of Teal Bend Golf Course and south along School House Road to the 

West Drainage Canal. Work includes dewatering and groundwater control, utility relocations, 

arch concrete culverts and headwalls, roadway crossings, irrigation and drainage inlets, and 

water control structures. 

11.1.3 Giant Garter Snake Drainage Canal – Reach C 

The total cost for the GGS/Drainage Canal in Reach C is $1,038,000. The cost is from the 

contractor bid dated July 2, 2009. 

SREL 1B 

The GGS/Drainage Canal construction consists of 6,300 feet of canal connecting to the North 

Drainage Canal at the north to Elverta Road at the south. The GGS/Drainage Canal will be 

constructed parallel to the Elkhorn Irrigation Canal and material excavated from the construction 

of the GGS/Drainage Canal may be used to construct the embankments for Elkhorn Irrigation 

26 


Canal. Two concrete arch culverts will be installed at points along the GGS/Drainage Canal. The 

two culverts are approximately 233 feet and 305 feet in length, and facilitate one crossing of 

Elverta Road and one crossing of Elkhorn Irrigation Canal respectively. Four check structures will 

be constructed along the length of the canal. 

11.1.4 NCMWC Chappell Ditch and Chappell pumps 

The total cost for the NCMWC Chappell Ditch and Pumps is $3,249,000. The cost is from the 


similar work and unit prices from product suppliers. Construction of the Chappell Ditch saves 

$1,600,000 in construction costs for Private Irrigation Relocation. Thus, $1,600,000 is allocated 

to Reach E relocations as discussed above, while the remaining 1,649,000 is allocated herein to 

drainage and irrigation improvements for mitigation. 

Improvements to the NCMWC service infrastructure will be required to serve irrigation water to 

the reclaimed Brookfield borrow site. These include extending and upgrading the Chappell Ditch 

to serve approximately 686 acres formerly supplied by wells, increasing the capacity of the 

Chappell No. 1 and 2 pumps, and replacing the Kaufman 1 well, which serves an area within the 

proposed Sutter Pointe Specific Plan.

MEMORANDUM 


To: 

John Bassett, PE 

Director of Engineering 


From: Bob Morrison, PE, Broker 

Right of Way Manager 

RE: 

Natomas Levee Improvement Program – Right of Way Budget 

The purpose of this memorandum is to provide a summary of the proposed real estate costs for 

the flood control footprint, borrow sites, and mitigation lands for the Natomas Levee 

Improvement Program (NLIP). The attached spreadsheets break out the real estate costs per U.S. 

Army Corp of Engineer's (USACE) planning Reach. The rounded total program costs for real 

estate are as follows: (these costs include a 5% contingency) 

LERRDS Flood Control Footprint $ 75,848,178 

Borrow Sites $ 26,653,725 

Mitigation Lands $ 17,909,463 

Total RE Costs: $120,411,366 

The definitions of each expense are as follows: 

Flood Control Footprint 

The real estate area budgeted for the flood control footprint includes the following: 

1. Existing Levee 

2. Adjacent Levee 

3. Seepage Berm 

4. Operation and Maintenance Corridors 

5. Utility Easements 

6. Irrigation Easements 

7. Drainage Easements 

The NLIP footprint is reasonably well defined along the Natomas Cross Canal and Sacramento 

River East Levee. Whenever possible the actual design was used to develop the budget numbers. 

The Levee Footprint is still in flux along the Pleasant Grove Creek Canal, Natomas East Main 

Drainage Canal, and American River North Levee. In these areas an assumption was made as to 

width and length of the right of way needed to construct the improvements. The cost analysis 

memos from HDR Engineering, Wood Rodgers and Mead & Hunt describe the acquisition areas. 

1

Borrow Sites 

The real estate area budgeted for borrow sites is defined as all lands acquired for dirt, with no 

second utility. This includes the airport borrow sites. These areas were acquired either in fee or 

as a negotiated purchase for the dirt only. 

Mitigation Lands 

The real estate area budgeted for mitigation lands is defined as all lands acquired for the project 

that will have an end use as mitigation. Much of the budget includes lands that have a dual use: 

borrow and mitigation. If there is a dual use, the budget for these properties in each instance is 

included in the mitigation account. 

In many instances the project acquisition expense for a given parcel included the flood control 

footprint, operation and maintenance corridors, utility corridors, irrigation easements, and 

woodland corridors (mitigation lands). Where applicable, the total acquisition cost was 

segregated between flood control footprint and mitigation lands. 

Mitigation costs appear in the Reach where the land acquisition occurred, however, AECOM has 

distributed total mitigation costs around the entire basin based on their calculations of a blended 

land cost for a combination of parcels. 

Budget Categories 

The budget categories for each parcel are as follows: 

1. Estimated Acquisition Cost – Sum of all lands and damages for a given parcel based on 

an estimated area of acquisition and an estimated land value. 

2. Appraised Value – Actual appraised amount offered to the property owner for lands and 

damages. 

3. Actual Acquisition Costs – the final costs of the lands and damages after acquiring the 

lands through negotiated settlement or eminent domain. 

4. Crop Loss – Actual or proposed costs paid to the tenant farmer to vacate their interest in 

the property acquired for the project. This includes agricultural damages e.g. wells, 

irrigation, and the loss in revenue by not harvesting a crop. 

5. RAP – Relocation Assistance Program costs. The actual or proposed cost to move a 

tenant or owner from the acquisition area to a new location. 

2

Assumptions 

Reach A 

1. Right of way acquisition for Reach A is based on a levee footprint that varies from 50 ft 

to 350 ft (per HDR), a Riverside Canal width of 150 ft to 200 ft (per Mead & Hunt), and 

a 20 ft width for the future Riverside Pipeline (per John Bassett). 

Reach B 

1. Actual acquisition costs or appraised values have been used. Land values for public 

agency acquisitions have been estimated. 

2. Value of any excess lands purchased for mitigation have been split out and shown on the 

Borrow/Mitigation figures 

Reach C 

1. Actual acquisition costs have been used. Land values for public agency acquisitions have 

been estimated. 

Reach D 

1. Actual acquisition costs or appraised values have been used. 

Reach E 

1. A width of 218 ft for the PGCC levee and infrastructure improvements along this reach 

has been supplied by Wood Rodgers. Damages and relocation costs are based on the 

impact of that width on specific parcels. 

2. Land acquisition acreages for Chappell Ditch and Chappell Drain were furnished by 

Mead & Hunt. The expense was allocated ½ to mitigation and ½ to land acquisition per 

Tim Washburn. 

Reach F 

1. A width of 181 ft for levee and infrastructure improvements along the Natomas East 

Main Drainage Canal and a total acreage requirement of 103.40 acres were supplied by 

Wood Rodgers. A total of 7.35 acres required for the Natomas Canal (Riego Road 

Canal) relocation was supplied by Mead & Hunt. Crop loss and relocation costs are 

based on the impact of that width on a specific parcel. Land values were estimated at 

$25,000 per acre from the PGCC to the first parcel contiguous with a TNBC parcel. At 

that point a value of $35,000 per acre for potential mitigation use was used. 

3

Reach G 

1. A width of 167 ft and a total acreage requirement of 72.70 acres were supplied by Wood 

Rodgers. Relocation costs were estimated based on the impact of that width on specific 

parcels. 

Reach H and Reach I 

1. No design has been completed. The real estate cost estimate for each reach was supplied 

by John Bassett based on anticipated design and impact.
