Natomas Levee Improvement Program - SAFCA

3.8.9 Summary – Reach H
When totaled, the cost estimates for each of the project accounts described above result in the USACE estimate for the NED Plan
being approximately $85 million higher than the SAFCA estimate for the 200-year project in Reach H. This difference is mainly
attributable to USACE’s much higher estimates for lands and damages, levee and floodwall construction and relocations reflecting the
more expansive footprint of the NED Plan in this reach. Table 8 provides a detailed comparison of these costs.
