Of* ^ USALLC (25)b46-4024 A. f 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 '3181$ square feet without written approval from the City of Renton. PERFORATED PIPE CONNECTION MAINTENANCE INSTRUCTIONS This lot contains stormwater management flow control BMP (best management practice) called a "perforated pipe connection," which was installed to reduce the stormwater runoff impacts of some or all of the impervious surface on your property. A perforated pipe connection is a length of drainage conveyance pipe with holes in the bottom, designed to "leak" runoff, conveyed by the pipe, into a gravel filled trench where it can be soaked into the surrounding soil. The connection is intended to provide opportunity for infiltration of any runoff that is being conveyed from an impervious surface (usually a roof) to a local drainage system such as a ditch or roadway pipe system. The size and composition of the perforated pipe connection 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. The soil overtop of the perforated portion of the system must not be compacted or covered with impervious materials. LIMITED INFILTRATION MAINTENACE Your property contains a stormwater management flow control BMP (best management practice) called"limited infiltration," which was installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious surfaces on your property. Limited infiltration is a method of soaking runoff from impervious area (such as paved areas and roofs) into the ground. Infiltration devices, such as gravel.filled trenches, drywells, and ground surface depressions, facilitate this process by putting runoff in direct contact with the soil and holding the runoff long enough to soak most of it into the ground. To be successful, the soil condition around the infiltration devicemust be able to soak water into the ground for a reasonable number of years. The infiltration devices used on your property include the following as indicated on the flow control BMP site plan:['gravel filled trenches,Cldrywells.The size, placement, and composition 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. Infiltration devices must be inspected annually and after major storm events to identify and repair any physical defects. Maintenance and operation of the system should focus on ensuring the system's viability by preventing sediment-laden flows from entering the device. Excessive sedimentation will result in a plugged or non-functioning facility. If the infiltration device has a catch basin, sediment accumulation must be removed on a yearly basis or more frequently if necessary. Prolonged ponding around or atop a device may indicate a plugged facility. If the device becomes plugged, it must be replaced. Keeping the areas that drain to infiltration devices well swept and clean will enhance the longevity of these devices. For roofs, frequent cleaning of gutters will reduce sediment loads to these devices. • HONEY CREEK EAST LOT 39 Permit No. 3735-NE 23RD PLACE PROJECT NARRATIVE This project is a new single family residence on a 7,926 sf. Lot. The area of disturbance shall be the entire lot. Excavation shall be for the foundation only. Total impervious are proposed is 3,818 sf. House, driveway and walkways will use 3,568 SF. The lots in Honey Creek East are restricted to a maximum of 3,000 square feet of impervious surface per drainage calculations. The approximate overage of 818 SF of impervious surfaces will be mitigated through the following methods: • 818 SF mitigated through 20 LF &42 LF Infiltration trenches per Figure C.2.2.A 2009 KCSWM manual • 250 SF of allowable impervious surface leftover for use by future homeowner DRAINAGE CONTROL Installing Infiltration Trench per Figure C.2.2.A 2009 KCSWM manual -See attached Restrictive Footprint Covenant restricting the lot to a total of 3,818 SF of impervious surfaces. EROSION CONTROL In order to prevent erosion and trap sediments within the project site,the following BMP's will be used approximately as shown on the ESC plan; • The clearing limits will thebe entire area of the lot and silt fencing shall placed along the entire perimeter to prevent sediments from leaving the site. • A 10'x20' construction entrance shall be installed at the front of the lot and composed of 4"-6" quarry spalls, 12" deep • Mulch will be spread over all cleared areas of the site when they are not being worked. Mulch will consist of air-dried straw and chipped site vegetation.
