INTRODUCTION This Operations and Maintenance Schedule is intended to provide guidance with respect to the amended soil contained on the CHC admin building site. 1. Post Construction Soil Quality and Depth it is the responsibility of the homeowners to ensure that all amended soil on the property is maintained by personnel that follow the recommendations within this manual. At the end of this manual is an example of a maintenance activity log. This log, or one similar, should be filled out any time maintenance is performed. The log must be kept on -site in a location that is accessible to City of Everett for inspection. FUNCTIONAL DESCRIPTION OF UNITS Post Construction Soil: These units are located throughout the site in landscaped areas where there is mulching and various plants. The purpose of these units is for stormwater to infiltrate the amended soil depth and decrease flows offsite. Failure to maintain these areas will result in stormwater water run-off and increased site flows to the municipal system. OPERATION AND MAINTENANCE BMP T5.13: Post -Construction Soil Quality and Depth is proposed and shall be maintained as according to the SWMMWW: • Establish soil quality and depth toward the end of construction and once established, protect from compaction, such as from large machinery use, and from erosion. • Plant vegetation and mulch the amended soil area after installation. • Leave plant debris or its equivalent on the soil surface to replenish organic matter. • Reduce and adjust, where possible, the use of irrigation, fertilizers, herbicides and pesticides, rather than continuing to implement formerly established practices.
