Phase I of the PUD built the Victoria Hills residentiai single family homes, and Phase II built a condominium complex (now the Montclair Heights Apartments). The stormwater facility was modified during Phase II construction to meet permit requirements to include stormwater runoff from Phase II. This included connecting the two Phase II drainage outfalls to the detention pond, increasing the pond storage capacity, and modifying the flow control FROP-Torifices. See attached Exhibit B, Phase I and Phase II Plan Sheets for Victoria Hills Starin Drain Detention Pond. The City does not own the detention pond facility. Renton Public Works staff is working with the Victoria Hills HOA, the stormwater facility owners, to transfer responsibility for long-term maintenance of the facility per the City's policy to assume maintenance for stormwater flow control facilities in single family residential plats. As an interim documented permission see attachment, Permission to Access and Maintain Stormwater Facility {#145407} within Victoria Hills Plat. Rolling Hills Creek, a class 4 stream, outfalls into south end of the detention pond facility and continues in a channel downstream the detention pond outlet. Three significant utilities structures are located adjacent to and down slope of the Victoria Hills stormwater facility's north berm. They are: Seattle Public Utilities 60" diameter water main, Olympic Pipeline Co. 16" oil and gas pipeline, City of Seattle power transmission line. Facility Maintenance Requirements: The proposed work is for long-term routine maintenance required to restore and preserve the ' flow control and water quality function of the existing stormwater detention facility, and to reduce risk of stormwater overflows into the Victoria Hills Community. This stormw_ater facility was designed and constructed in accordance with the_PUD permit requirements. Proper maintenance and operation of this stormwater detention facility is needed to prevent flooding and property damage (including the utilities described above, as well as down slope residential properties), protect public safety, protect environmental resources, and to bring the facility to • • maintenance standards per the City adopted 2009 King County Surface Water Design Manual, Appendix A. Facility Maintenance Activities: Primary maintenance tasks include removing accumulated sediment from within the detention pond, maintenance and repair of the pond inlet pipe and outlet pipes, control structure and perimeter fence, and facility vegetation maintenance. See attached Exhibit C, Facility Maintenance Site Plan. Note: see section below, Minimizing Adverse Impacts ta the Aquatic Environment. Long-term routine stormwater facility maintenance activities will include: Restore and maintain road surface of existing access road (top of north berm) -includes removal of 6 trees (>6" dia.) -may include small quantity of fill Restore and maintain bank slope of north berm -includes removal of 7 trees (>6" dia.) Remove accumulated sediment from north end of detention pond bottom (see Exhibit-A). -up to 300 cubic yards accumulated sediment (within 3,900 ft.2 area) -includes removal of brush & small trees growing within the sediment(< 6" dia.) -an excavator will remove accumulated sediment. The removed sediment material will be trucked off site. When sediment excavation is complete all wheel tracks and ruts will be healed, grass seed will be spread and straw placed over the grass seed. Maintain & repair pond inlet/outlet pipes, catch basins & control structure Vegetation maintenance -control invasive plants and maintain grass ground cover Replace & maintain perimeter fence -remove existing 6' high wooden fence and replace with 6' vinyl coated chain link fence -may include tree removal, however all effort will be given to minimize impacts to trees by locating the replaced fencing to avoid tree removal Maintenance Activity Timeline: The maintenance activities timeline would be subject to a required WDFW Hydraulic Project Approval provisions. Immediate Maintenance: This work will focus on restoring the facility functionality. It is anticipated to occur during Spring through Fall 2014, beginning as soon as conditions are dry enough.· It will focus on restoring the maintenance road surface, restoring the bank slope of north berm, and removing accumulated sediment. These maintenance activities are estimated to take 4 weeks total. • • The fence replacement will be scheduled per the Public Works Stormwater Facility Fencing Project budget and prioritization. Long-term Routine Maintenance: The most frequent occurring routine work will be vegetation maintenance activities that will be completed within 1 day, and will be performed at a minimum 3-4 times per year. All other maintenance activities listed in the above section will be performed as nee.ded (anticipated to occur on an infrequent basis). It is unknown how quickly sediment will again accumulate to a level requiring removal.. A best estimate is that removal of accumulated sediment will need to be done every 3-5 years. Minimizing Adverse Impacts to the Aquatic Environm_ent: Rolling Hills Creek, a class 4 stream, outfalls into the south end of the detention pond facility and continues in a channel downstream the detention pond outlet. Wheri the maintenance work is performed, stream flow from this creek will be diverted around the work area within the detention pond, through a temporary pipe to the existing rock channel below the detention pond outlet pipe outfall. The Regional Road Maintenance Endangered Species Act Program Guidelines will be used to select and implement appropriate Best Management Practices to minimize the disruption to the natural environment. Work will also comply with other regulations protecting water · quality, endangered species, shorelines, and sensitive areas: Specific Regional Road Maintenance Guidelines that will be referred to include Maintenance Category# 4 Open Drainage Systems. Outcome Categories: . . . • Keep water from work area. BMP 2.49-2.107.-2.97 • Reduce potential for soil erosion. BMP 2.73-2.97-2.120 • Habitat protection/maintenance.

Phase I of the PUD built the Victoria Hills residential single family homes, and Phase II built a condominium complex (now the Montclair Heights Apartments). The stormwater facility was modified during Phase II construction to meet permit requirements to include stormwater runoff from Phase II. This included connecting the two Phase II drainage outfalls to the detention pond, increasing the pond storage capacity, and modifying the flow control FROP-T orifices. See attached Exhibit 8, Phase I and Phase II Plan Sheets for Victoria Hills Storm Drain Detention Pond. The City does not own the detention pond facility. Renton Public Works staff is working with the Victoria Hills HOA, the stormwater facility owners, to transfer responsibility for long-term maintenance of the facility per the City's policy to assume maintenance for stormwater flow control facilities in single family residential plats. Rolling Hills Creek, a class 4 stream, outfalls into south end of the detention pond facility and continues in a channel downstream the detention pond outlet. Three significant utilities structures are located adjacent to and down slope of the Victoria Hills stormwater facility's north berm. They are: Seattle Public Utilities 60" diameter water main, Olympic Pipeline Co. 16" oil and gas pipeline, City of Seattle power transmission line. Facility Maintenance Requirements: The proposed work is for long-term routine maintenance required to restore and preserve the flow control and water quality function of the existing storm water detention facility, and to reduce risk of stormwater overflows into the Victoria Hills Community. This stormwater facility was designed and constructed in accordance with the PUD permit requirements. Proper maintenance and operation of this storm water detention facility is needed to prevent flooding and property damage (including the utilities described above, as well as down slop_e residential properties), protect public safety, protect environmental resources, and to bring the facility to maintenance standards per the City adopted 2009 King County Surface Water Design Manual, Appendix A. • • 4-.2...'7-l 4 _f-~~ /J. 0 d ;(, /l.C..(e.J.J.e S [;_11 __ 1f __ f..S __ _J..tf'C,ff__FC l..rJ-.I1fx_ /V/J',-t,~r/-7'1 n;_ .fi-ff,t/ L,_d_Lt. /!-f" ,tr/1-r --""-]>=t;-:S::::...,C!Cf 13. €_ T.lK. /'1/1-/NTtPl't/f/{:.,(; WOjc.lf_ fl:.E9_ v1,ecj) Fo;e. ----'-11: c_:,c;/t r /f-!:f/£L-S .l)f:lff;vTldrtJ __ B__v_4~---------- __ f-,!£Jtf:&.:._ £a::. /-t,e 1__-1_',,-,Jo 4l Lr __ cJ_tJu ,,.)ecf1J fr.NL.i:12l>!.T/dtV«t.. }_/V pott,.;lf /17?cJAI.

See attached Exhibit C, Facility Maintenance Site Plan. Long-term routine stormwater facility maintenance activities would include: Restore and maintain road surface of existing access road (top of north berm) -includes removal of 6 trees (>6" dia.) -may include small quantity of fill Restore and maintain bank slope of north berm -includes removal of 7 trees (>6" dia.) Remove accumulated sediment from north end of detention pond bottom -up to 300 cubic yards accumulated sediment (within 3,900 ft. 2 area) -includes removal of brush & small trees(< 6" dia.) Maintain & repair pond inlet/outlet pipes, catch basins & control structure Vegetation maintenance -control invasive plants and maintain grass ground cover Replacement & repair perimeter fence -may include tree removal, however all effort will be given to minimize impacts to trees by locating the replaced fencing to avoid tree removal Minimizing Adverse Impacts to the Aquatic Environment: Rolling Hills Creek, .a class 4 stream, outfalls into the south end of the detention pond facility and continues in a channel downstream the detention pond outlet. When the maintenance work is performed, stream flow from this creek will be diverted around the work area within the detention pond, through a temporary pipe to the existing rock channel below the detention pond outlet pipe outfall. The Regional Road Maintenance Endangered Species Act Program Guidelines will be used to select and implement appropriate Best Management Practices to minimize the disruption to the natural environment. Work will also comply with other regulations protecting water quality, endangered species, shorelines, and sensitive areas. Specific Regional Road Maintenance Guidelines that will be referred to include Maintenance Category# 4 Open Drainage Systems. Outcome Categories: • Keep water from work area.
