Natomas Levee Improvement Program - SAFCA

SAFCA’s estimate also includes costs for lands and damages administration that
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.
3.5.4 Relocations
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
percent contingency.
The USACE estimate for relocations in Reach E is about 20 percent lower than SAFCA’s
estimate when contingencies are included.
3.5.5 Planning Design and Engineering
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.
3.5.6 Cultural Resources
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.
The USACE estimate contains only a total cost for cultural resources that is not broken
out by reach.
3.5.7 Construction Management
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.
