9. WATER QUALITY DESIGN Minimum Requirement#6: Runoff Treatment This project will create more than 5,000 sf of drivable surfaces but the majority of those surfaces will be pervious pavement which is not considered PGIS. However, based on the Geotechnical Engineer's findings of the soil beneath the proposed pervious asphalt the existing soil conditions will provide the necessary treatment of the pavement surface runoff as part of the infiltration process. This will also apply to the driveway runoff dispersed over the existing vegetation and amended soils. 10. WETLAND PROTECTION Minimum Requirement#8 No wetlands were found on this site and during the site visit and downstream analysis/review no wetlands were found in the downstream offsite path as well. 11. OPERATIONS AND MAINTENANCE MANUAL The Property Owner Association will be responsible for maintaining the stormwater and landscaping facilities within this development. Included in this manual are checklists for each feature specific to this project. Copies should be made of the checklists as necessary during routine inspections and required maintenance. Specific problems can be recorded along with the appropriate action taken. These checklists are a guide for inspections and maintenance. The frequency of the inspections/maintenance is identified in the left hand column with the following abbreviations: A =Annual (March or April preferred) M = Monthly S =After Major Storms (Use 1-inch in 24 hours as a guideline) Routine inspections and maintenance will improve the long-term performance of the stormwater facilities. If at any time you are unsure if a problem exists or how to address a specific problem contact a Professional Engineer. Refer to the following sheets a list of each facility to be maintained and the appropriate maintenance checklist. Thompson Short Plat 11-012 May 2011 Page 16
