DMA Design Workbook InstructionsNote: This workbook does not take the place of good engineering judgment. Engineering judgment should be used when designing BMPs to meet the SWDS requirements.
Note: RBF Consulting, A Company of the Michael Baker Corporation, does not guaranty that the sizing calculations are correct. Users are encouraged to verify results and to provide the City of Salinas and RBF at [email protected] with feedback to correct errors and/or make improvements. Consider this tool to be a "beta" version
The purpose of this workbook is to assist project applicants for new and redevelopment projects in appropriately sizing BMPs to meet requirements set forth by the City of Salinas and the Central Coast Regional Water Quality Board. This spreadsheet workbook is constructed to serve as a tool to determine the requirement set a project is subject to and to design Best Management Practices (BMPs) to meet the applicable stormwater requirements. Included in this workbook are the summary sheet, threshold determination process spreadsheet and worksheets for bioretention design by Drainage Management Area (DMA). All projects are required to submit the Threshold Determination Spreadsheet with their conceptual stormwater control plan. For projects subject to Requirements 3 4 or 5 the entire workbook is to be turned in with the Stormwater Control Plan
Most user populated data is contained within the Threshold Determination Process and DMAs worksheets. User populated cells have borders and cells that are not greyed out. The greyed out cells are populated with data generated using the user populated data When an applicant fills out the workbook, the applicant should be sure to populate the cells in the Threshold Determination Process Spreadsheet in addition to the appropriate number of DMA spreadsheets for your project. Additional DMA worksheets can be added. If additional DMAs are required, please copy the last DMA tab, rename it to the same naming scheme “DMA #” and copy the appropriate cells, starting in column N, on the summary sheet to include the additional DMAs in the summary page. Remember to revise the new DMA sheet cell A2. Warning: We know that when DMA worksheets are copied that Excel takes an extended period of time to process the additional sheets Please be patient with Excel! If you encounter problems copying worksheets
Threshold Determination ProcessThe Threshold Determination Spreadsheet includes fields to categorize pervious and impervious features beyond that necessary to determine requirement applicability to promote identification of potential opportunities to increase the effective pervious area and to aid in project review. The applicant has the option to lump areas into the “All or Other” category, with the exception of turf areas, for cases where a more detailed breakdown would require extensive effort without potential benefit. This sheet is to be used to determine the appropriate SWDS requirement set for the proposed project
DMA WorksheetsEach DMA has a dedicated worksheet for BMP design purposes. In each DMA worksheet, be sure to input the appropriate infiltration rate. Each DMA workbook has the same base calculations. The workbooks are capable of four different treatment types or configurations: flow based treatment, volume based treatment, flow based pre treatment and self treating This workbook contains both pull-down menus and cells to be populated. The pull-down menus are included to aid in designing appropriate BMPs for each DMA. This workbook also allows the user to have the workbook automatically size and locate the orifice, notch base and top of riser. If the BMP is not being designed for Peak Management, be sure to select "No" in response to the question. The BMP will then be sized for the required volume at the overflow and the specific overflow configuration will not be specified

For the "Flow Based Pretreatment" Option, both the flow-based and volume based portions of the spreadsheet are active to evaluate configurations that use pretreatment upstream from infiltration systems.
For volume based treatment, the spreadsheet methodology is based on the BMPs full area residing at the BMP’s bottom elevation. The worksheets are not set up to design an infiltration basin where the infiltration area
When using the workbook, it is recommended that the Automatic calculations be turned off, in the Calculation Options under the Formulas tab, and manual calculations are selected instead. When a sample BMP has been designed, select the “Calculate Now” in the Formulas tab to make the Excel process more efficient.
