Summary of BMP Site Characteristics

Notes:
1. Drain Inlet Insert (a) = Fossil Filter® type
Drain Inlet Insert (b) = Stream Guard® type

2. Construction costs include allowances for water quality monitoring. The cost of widescale retro- fitting will be affected by factors such as economies of scale and contractor experience. Costs are approximate as of 6/30/00.

3. Constraints Codes:t
AA = Area Available - restricts BMP size, dimensions, and/or location
CZ = Coastal Zone - minimizes BMP encroachment of existing trees
HA = Headloss Available - restricts BMP location/design (p = pump required)
UT = Utilities Restricted - restricts BMP location by existing utility design
DW = Watershed Diversion - watershed diverted or modified to flow into BMP
RZ = Recovery Zone - 30-foot buffer from pavement required for errant vehicles
4. See Regional Basin Plan by Regional Water Quality Control Boards for definitions.

("I" = Intermittent Use)

Timeline for BMP Pilots*
