After the 30 days,the Owners shall allow the City of Renton to enter for the sole purpose of inspecting the BMPs. In lieu of inspection by the City,the Owners may elect to engage a licensed civil engineer registered in the state of Washington who has expertise in drainage to inspect the BMPs and provide a written report describing their condition. If the engineer option is chosen,the Owners shall provide written notice to the City of Renton within fifteen days of receiving the City's notice of inspection. Within 30 days of giving this notice,the Owners,or the engineer on behalf of the Owners,shall provide the engineer's report to the City of Renton. If the report is not provided in a timely manner as specified above,the County may inspect the BMPs without further notice. 4. If the City determines from its inspection,or from an engineer's report provided in accordance with Paragraph 3,that maintenance,repair,restoration,and/or mitigation work is required for the BMPs, The City shall notify the Owners of the specific maintenance,repair,restoration,and/or mitigation work (Work)required under RMC 4-6-030. The City shall also set a reasonable deadline for completing the Work or providing an engineer's report that verifies completion of the Work. After the deadline has passed,the Owners shall allow the City access to re-inspect the BMPs unless an engineer's report has been provided verifying completion of the Work. If the work is not completed properly within the time frame set by the City,the City may initiate an enforcement action. Failure to properly maintain the BMPs is a violation of RMC 4-6-030 and may subject the Owners to enforcement under the RMC 1-3,including fines and penalties. 5. Apart from performing routine landscape maintenance,the Owners are hereby required to obtain written approval from the City or Renton before performing any alterations or modifications to the BMPs. 6.

TEXT OF INSTRUCTIONS • Your property contains a stormwater management flow control BMP(best management practice)called"full dispersion." Full dispersion is a strategy for minimizing the area disturbed by development(i.e.,impervious or non-native pervious surfaces,such as concrete areas,roofs,and lawns)relative to native vegetated areas(e.g.,forested surface)together with the application of dispersion techniques that utilize the natural capacity of the native vegetated areas to mitigate the stormwater runoff quantity and quality impacts of the 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 native vegetated area. Dispersion Devices The dispersion devices used on your property include the following as indicated on the flow control BMP site plan:D splash blocks,❑rock pads,U 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 maynot be changed without written approval either from the King County Water and Land Resources Division or through a future development permit from King County. Dispersion devices must be inspected annually and after major storm events to identify and repair any: physical defects: Whennativesoil is exposed or erosion channels are present,the sources of the erosion or concentrated flow need to be identified and mitigated. Bare spots should be re-vegetated with native vegetation. Concentrated flow can be mitigated by leveling the edge of the pervious area and/or regrading or replenishing the rock in the dispersion device,such as in rock pads and gravel-filled trenches. Native Growth Retention Area The native vegetated surface required for full dispersion is delineated as a"native growth retention area" on the flow control SMP site plan. The trees,vegetation,ground cover,and soil conditions in this area may not be disturbed,except as allowed by the following provisions for that portion of the native growth retention area outside of critical areas and critical area buffers: 1. Trees may be harvested in accordance with a King County-approved forest management plan. 2. Individual trees that have a structural defect due to disease or other defects,and which threaten to damage a structure,road,parkingarea,utility,or place of employment or public assembly,or block 9 tY emergency access,may be topped,pruned,or removed as needed to eliminate the threat. 3. Dead or fallen trees,tree limbs within ten feet of the ground,and branches overhanging a residence may be removed to reduce the danger of wildfire. 4. Noxious weeds(i.e.,plant species listed on the State noxious weed list in Chapter 16-750 WAC)and invasive vegetation(i.e.,plant species listed as obnoxious weeds on the noxious weed list adopted by the King County Department of Natural Resources and Parks)may be removed. 5. Passive recreation uses and related facilities,including pedestrian,equestrian community and bicycle trails,nature viewing areas,fishing and camping areas,and other similar uses that do not require permanent structures,are allowed if clearing and soil compaction associated with these uses and facilities does not exceed eight percent of the native growth retention area.

The intent of these instructions is to explain to future property owners,the purpose of the BMP and how it must be maintained and operated. These instructions are intended to be a minimum;DDES may require additional instructions based on site- specific conditions. Also,as the County gains more experience with the maintenance and operation of these BMPs,future updates to the instructions will be posted on King County's Surface Water Design Manual website: - U TEXT OF INSTRUCTIONS Your property contains a stormwater management flow control BMP(best management practice)called "full infiltration,"which was installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious surfaces on your property. Full infiltration is a method of soaking runoff from impervious area(such as paved areas and roofs)into the ground. If properly installed and maintained,full infiltration can manage runoff so that a majority of precipitation events are absorbed. Infiltration devices,such as gravel filled trenches,drywells,and ground surface depressions,facilitate this process byputtingrunoff 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 device must be reliably 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:CI gravel filled trenches,Q drywells,0 ground surface depressions_ 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 either from the King County Water and.Land Resources Division or through a future development permit from King County. 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.
