In the space provided below, briefly summarize how the stormwater runoff will be treated. Stormwater runoff will be treated in two Bioretention basins and one Wet Pond. Grass swales and channels will be utilized in areas around the site to convey runoff to the Bioretention basins Pretreatment for these basins will be by the use of grassed swales as well as a gravel and crass strip around the parking lot. A piped system with grass swales leading to the inlets of the system will outlet into the proposed Wet Pond. The pretreatment for the Wet Pond will be accomplished through the use of forebays. 2. a.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the 13MP. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. Important maintenance procedures: — Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. — If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. — Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: Potentialproblem: I -low I will remediate theproblem: The entire BMP Trash/debris is present. Remove the trash/debris.

In the space provided below, briefly sunvnarize how the stormwaler runoff will betreated. Stormwater runoff will be treated in two Biorctention basins and one Wet Pond. Crass swales and channels Will be utilized in areas around the site to convey runoff to the Biorelention basins. Pretreatment for these basins will be by the use of grassed swales as well as a gravel and grass strip around the parking lot A piped system with grass swales leading to the inlets of the system will outicl into the proposed Wet Pond. The pretreatment for the Wet Pond will be accomplished through the use of forebays. 1 2. a.
