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, fee revenue, and other local, state, and federal funding. The total contract amount of $1,141,242 is based on the fee presented in the proposal by WEST Consultants, Inc. Sufficient appropriation and revenue have been included in the District’s 2022-23 budget (1970002510-FL0115) and will be included in future recommended budgets.
BACKGROUND INFORMATION
The District’s first San Bernardino County Hydrology Manual (Hydrology Manual) was released in May 1983 and updated in August 1986. In September 1987, the District issued Detention Basin Design Criteria to be used by agencies and developers in the development of land, and the design and construction of required detention basins. Since then, the District has not comprehensively updated the Hydrology Manual or the Detention Basin Design Criteria, though the District issued an addendum to the Hydrology Manual in April 2010 to address arid regions in the County. The District, County residents, public agencies, and developers all rely upon and use the Hydrology Manual and Detention Basin Design Criteria to prepare hydrology analyses for any proposed new projects, drainage studies, Comprehensive Storm Drain Plans, and Master Plans of Drainage.
Under the proposed contract, WEST Consultants, Inc. will provide professional civil engineering services to update the current Hydrology Manual and Detention Basin Design Criteria, which will include updates due to climate change considerations. Services may be further added or deleted, as required, and authorized by the Chief Flood Control Engineer or the Assistant Director pursuant to the terms of the contract, to complete the work outlined in the contract, if such modification does not increase the total cost or change the term of the contract. WEST Consultants, Inc. is well-versed in multiple hydrology modeling software programs and will provide algorithms in an Excel workbook to accommodate both large and small projects. A single spreadsheet concept for calculations would also simplify District reviews.
The proposed update to the Hydrology Manual and Detention Basin Design Criteria will provide more detail and flexibility in the hydrology calculation by using new technology and software that will increase productivity and improve workflow with more quality control. Ultimately, the proposed update to the Hydrology Manual and Detention Basin Design Criteria will assist County residents and developers when preparing hydrology analyses for new development.
PROCUREMENT
