Natomas Levee Improvement Program - SAFCA

3.9.4 Lands & Damages
A small amount of residential and commercial land is needed to accommodate the 200-
year project footprint in Reach I. SAFCA’s estimate of the cost of this land is based on an
opinion of probable value and includes a 10 percent contingency.
SAFCA’s estimate also includes costs for lands and damages administration that
represent 30 percent of the value of the land acquired.
The USACE estimate for lands and damages including administration is almost two 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.
3.9.5 Relocations
SAFCA’s estimate includes costs for relocating electrical utility poles and lines along the
landside toe 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 30 percent contingency.
The USACE estimate for relocations in this reach is about two times higher than
SAFCA’s estimate based on the NED Plan’s enlarged footprint.
3.9.6 Planning Design and Engineering
SAFCA’s estimate for planning, engineering and design costs in Reach I includes costs
incurred through 2010 and cost projections for completing the engineering and design of
the 200-year project features in this reach. This estimate represents approximately 24
percent of the estimated costs for construction and relocation work. The USACE estimate
for these activities is more than twice as high as SAFCA’s estimate, presumably because
of the NED Plan’s larger footprint.
3.9.7 Cultural Resources
SAFCA’s estimate of cultural resources costs for this reach covers potential monitoring
and resource recovery activities. The estimate represents approximately 1.7 percent of
total construction and relocation costs.
The USACE estimate contains only a total cost for cultural resources that is not broken
out by reach.
3.9.8 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 I is comparable to
SAFCA’s estimate.
