FINANCIAL IMPACT
Approval of this item will not result in the use of Discretionary General Funding (Net County Cost). The San Bernardino County Flood Control District (District) is funded by property taxes, fees, and other local, state, and federal funding. The total cost of this agreement is $247,149 and will be funded by property tax revenue. Sufficient appropriation and revenue are included in the District’s 2023-24 budget (1940002532 F01854) and will be included in future recommended budgets.
BACKGROUND INFORMATION
The Desert Knolls Wash Phase III Project (Project) proposes to control flow velocities by constructing bank and invert stabilization improvements within an approximate 0.6-mile segment of Desert Knolls Wash within the Town of Apple Valley. Project activities include grading stream banks to a 2:1 slope and constructing bank stabilization with grouted and un-grouted rock slope protection. The Project also includes constructing a series of grade stabilization structures, or rock invert, with grouted and un-grouted rock across the earthen streambed bottom to prevent erosion.
Additional Project activities include constructing an access road along the southern side of the streambed that may be paved or fenced to facilitate access to the Project and for future maintenance. The access road will continue over the streambed in the northern portion through installation of a culvert with concrete headwalls and wingwalls, and safety barrier.
On July 25, 2017 (Item No. 66), the Board of Supervisors (Board) approved the Project and adopted a Mitigated Negative Declaration (MND) for the Project pursuant to the California Environmental Quality Act. Under the proposed agreement, Leatherman BioConsulting, Inc. (Leatherman) will conduct biological resource monitoring during Project construction as required by the MND and regulatory permitting for the Project.
The Project meets the Chief Executive Officer's goals and objectives to provide for the safety, health, and social service needs of San Bernardino County residents by attenuating flows to reduce the potential for downstream flooding in both large and small storm events, and to provide flood protection for the existing structures and residences within the Project area by constructing flood control improvements while working with other agencies to minimize and mitigate for related environmental impacts.
