TITLE: DATE • I. EXHIBIT B RESTRICTIVE FOOTPRINT MAINTENANCE INSTRUCTIONS Your property contains a stormwater management flow control BMP (best management practice) known as"restricted footprint,"the practice of restricting the amount of impervious surface that may be added to a property so as to minimize the stormwater runoff impacts caused by impervious surface.The __ total impervious surface on your property may not exceed _7 square feet without written approval from the City of Renton. 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 dispersion devices used on your pro rty include the following as indicated on the flow control BMP site plan: ❑ splash blocks, ❑ rock pads, gravel filled trenches, ❑ sheet flow.The size, placement, composition, and downstream flowpat s 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. PERMEABLE PAVEMENT MAINTENANCE INSTRUCTIONS Your property contains a stormwater management flow control BMP(best management practice)called "permeable pavement,"which was installed to minimize the stormwater quantity and quality impacts of some or all of the paved surfaces on your property. Permeable pavements reduce the amount of rainfall that becomes runoff by allowing water to seep through the pavement into a free-draining gravel or sand bed,where it can be infiltrated into the ground. EXHIBIT B Permeable Pavement The type(s)of permeable pavement used on your property is:Xporous concrete, D porous asphaltic concrete, ❑ permeable pavers, 0 modular grid pavement. The area covered by permeable pavement as depicted by the flow control BMP site plan and design details must be maintained as permeable pavement and may not be changed without written approval from the City of Renton. Permeable pavements must be inspected after one major storm each year to make sure it is working properly. Prolonged ponding or standing water on the pavement surface is a sign that the system is defective and may need to be replaced. If this occurs, contact the pavement installer or the City of Renton for further instructions. A typical permeable pavement system has a life expectancy of approximately 25-years. To help extend the useful life of the system, the surface of the permeable pavement should be kept clean and free of leaves, debris, and.sediment through regular sweeping or vacuum sweeping.The owner is responsible for the repair of all ruts, deformation,and/or broken paving units.
