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.

PROJECT INFORMATION -1. In the space provided below, briefly summarize how the stormwater runoff will be treated. The site will be graded to flow into a piped storm drainage system into the forebay of the wet pond. There is also a pipe extention for future development across N. Main St. The volume for the future area has been included in the calculations. The flow will pass through the riprap baffle to remove TSS and plantings along the literal shelf will remove floating oils and process organics. Water quality drawdown time is two days to allow sedimentation. Water will be released through the riser and outlets stem and discharged into an existing storm drain passing beneith Pearl Circle. 2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved: ❑ Approval of a Site Specific Development Plan or PUD Approval Date: ❑ Valid Building Permit Issued Date: ❑ Other: Date: b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with: ❑ Coastal SW - 1995 ❑ Ph II - Post Construction 3. Stormwater runoff from this project drains to the Rocky River basin. 4. 'Total Property Area: 6.55 acres 5. Total Coastal Wetlands Area: 0 acres 6. Total Surface Water Area: 9.68 acres 7.

The resultant project area is used to calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NNW (or MHW) line may be included in the total project area. 8.

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 BMP.

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.
