CITY OF PUYALLUP Office of the City Engineer 333 S Meridian Puyallup, WA 98371 ver.2017-July Permeable Pavement Maintenance Plan City of Puyallup Rain Garden Program Overview The City of Puyallup Rain Garden Program is designed to provide education and outreach to residents on the benefits and application of rain gardens, rainwater harvesting and permeable pavements. As a participant in the program, you have agreed to have a permeable pavement installed on your property. Your permeable pavement – a stormwater facility – helps to filter pollutants from stormwater and infiltrate stormwater into the ground. Goals and Objectives Limited maintenance and upkeep is necessary to ensure that your stormwater facility continues to function as intended including filtering of stormwater to remove pollutants and infiltrating the filtered stormwater into the ground. The Preventative Maintenance section of this document provides guidance for proper maintenance of your permeable pavement. This plan follows the direction given by the City and its affiliates when your permeable pavement was installed and/or approved. For more information, please refer to the Low Impact Development Technical Guidance Manual for Puget Sound (2012, or updated version). - by Washington State University Extension – for additional details on appropriate permeable pavement maintenance and procedures. Any significant changes to your pavement should be developed in consultation with the City’s Stormwater Engineer. Changes shall be approved in writing by the Stormwater Engineer or his/her designee. Please attach drawings of any proposed changes to your pavement. Preventative Maintenance To keep your permeable pavement looking its best, and functioning properly, please remember to follow these preventative maintenance steps: 1. Weed regularly, as needed 2. Maintain vegetation around pavement to minimize sediment/dirt deposition onto the pavement 3. Replace broken pavers that affect the structural integrity of the surface 4. Replenish aggregate joint materials as needed per your paver manufacturer specifications; contact the installer if unsure 5. Vacuum sweep annually, in dry weather ---PAGE BREAK--- CITY OF PUYALLUP Office of the City Engineer 333 S Meridian Puyallup, WA 98371 ver.2017-July 6. DO NOT apply traction salt/sand to the pavement, this may cause the surface to clog, preventing the pavement from infiltrating stormwater 7. DO NOT stockpile aggregate materials (ie: dirt, rocks, wood) directly on pavement – place a tarp or other structure underneath to protect pavement; these materials may clog the surface 8. Perform annual inspections using the attached Annual Inspection Checklist (and submit a copy to the City to meet reporting requirements) Reporting Requirements To ensure proper maintenance and adherence to the aforementioned Plan, you are required to submit a completed copy of the attached Permeable Pavement Annual Inspection Checklist to the City of Puyallup annually.
