and be collected in a drainage pipe installed within and around the perimeter of the play area. The drainage pipe will be connected to the existing drainage system outside of the play area.

A quarry spall rock apron will be constructed at the outfall to dissipate any flow from the drainage pipe. Minimum Requirements The Small Project Site Plan/Report form(Attachment D) was prepared to show compliance Minimum Requirements #1-5. The following highlights key information from the form. Minimum Requirement#2—Construction Stormwater Pollution Prevention Plan SWPPP Parks will be responsible for preventing erosion and sedimentation during construction, including these activities: • Minimize construction track-out. BMP C105: Stabilize construction entrance/exit. • Construction staging and play equipment stockpiling will be located in the adjacent parking lot and outside sensitive areas. • BMP C233 will be used to protect slopes to the east. • BMP C220 and C209 will be used for catch basin inlet protection and the existing drain line leaving the playground area. • BMP C151 and BMP C154 will be used for concrete handling concrete and washout activities. • Any materials needed for erosion prevention and sedimentation control will be kept at the project site (BMP C150). • Construction sequencing will be done in a manner that reduces the amount and duration of soil exposed to erosion by wind,rain,runoff, and vehicle tracking (BMP C162). Minimum Requirement#3 — Source Control BMPs Parks must apply these Source Control BMPs to the project site: • Section V-1 Source Control BMPs Applicable to All Sites (e.g., good housekeeping, employee training, inspections, recordkeeping, etc. which are a part of Parks' normal operations) • S411 BMPs for Vegetation Management(which are a part of Parks' normal operations) • BMP 5421 for parking and storage of vehicles and equipment
