' .'r �' - ; TITLE: DRAINAGE DATE: MAY 13,2014 2814 PARK AVE N EXHIBIT B BASIC DISPERSION MAINTENANCE INSTRUCTIONS Your property contains a stormwater management flow control BMP(best management practice)called "basic dispersion," which was installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious surfaces or non-native pervious surfaces on your property. Basic dispersion is a strategy for utilizing any available capacity of onsite vegetated areas to retain, absorb, and filter the runoff from developed surfaces. This flow control BMP has two primary components that must be maintained: (1)the devices that disperse runoff from the developed surfaces and (2) the vegetated area over which runoff is dispersed. Dispersion Devices The dispersipn devices used on your property include the following as indicated on the flow control BMP site plan: I?J splash blocks, firock pads, ❑ gravel filled trenches, ❑ sheet flow.The size, placement, composition, and downstream flowpaths of these devices as depicted by the flow control BMP site plan and design details must be maintained and may not be changed without written approval from the City of Renton. Dispersion devices must be inspected annually and after major storm events to identify and repair any physical defects.When native soil is exposed or erosion channels are present,the sources of the erosion or concentrated flow need to be identified and mitigated. Concentrated flow can be mitigated by leveling the edge of the pervious area and/or realigning or replenishing the rocks in the dispersion device, such as in rock pads and gravel filled trenches. Vegetated Flowpaths The vegetated area over which runoff is dispersed must be maintained in good condition free of bare spots and obstructions that would concentrate flows.
