MARIN_HYDROLOGY_RAINFALL_DEPTH_1YR_1HR

This layer provides geospatially distributed design storm rainfall depths in inches for the 1-year recurrence interval and 1-hour duration in Marin County. It is intended for use in calculations to determine sizing for bioretention systems (green stormwater infrastructure - GSI) to meet water quality and trash capture requirements under the stormwater permit issued by the State of CA Water Resources Control Board.
