PROJECT NUMBER:LUA15-000864,ECF,CU-H,SA-H,MOD
APPLICANT:City of Renton,Public Works
PROJECT NAME:Highlands Reservoir &Emergency Generator
PROJECT DESCRIPTION:The applicant is requesting Environmental (SEPA)Review,Hearing
Examiner Site Plan and Conditional Use Permit Reviews,and a Modification to street improvements for

MITIGATION MEASURES:
1.The applicant shall comply with the recommendations included in Technical
Memorandum Review of Existing Geologic,Hydrogeologic,and Geotechnical
Information,prepared by RH2 Engineering Inc,dated December 19,2014 and
Geotechnical Report,prepared by ZZA-Terracon,dated January 19,2009 (Exhibit 8).

WATER
1.The proposed development is within City of Renton Water District.
SANITARY SEWER
1.Sewer service is provided by the City of Renton.The future phase will require a cut and cap of the existing
side sewer connection for the chlorination building and vault.
SURFACE WATER
2.A drainage report complying with the 2009 King County Surface Water Design Manual and City of Renton
Amendments to the KCSWDM,was submitted from RH2 Engineering,Inc.dated November 2015.Based on the
City’s flow control map,this site falls within the Flow Control Duration Standard,Forested Site Conditions (north and
east sides of the site;Honey Creek Basin)and the Peak Rate Flow Control Standard,existing site conditions (south
and west sides of the site;Johns Creek Basin).A Full Drainage Review was included in the report and is for
construction of the Phase 1 reservoir and planning for the stormwater system expansion in Phase 2.A flow control
BMP is required;the TIR proposes permeable subgrade with traditional asphalt over the top and call it “Permeable
Asphalt”.The geotech report says the soil is not suitable for infiltration so a different BMP needs to be proposed.
The project will need to submit an adjustment for approval of the pump system.The final drainage plan and drainage
report must be submitted with the utility construction permit application.
3.A geotechnical report from 2009 authored by ZZA Terracon was submitted with a December 2014 Technical
Memorandum to the 2009 geotech report.RH2 reviewed ZZA Terracon’s findings and recommendations as well as
provided a summary regarding infiltration potential for on site stormwater management.RH2 classified the soil
conditions on site to have a low infiltration capacity and therefore is not suitable for on site infiltration of stormwater.
The earthwork portion of the project is recommended to be accomplished during extended dry periods of weather;if
earthwork is done during the west season extra precautionary measures will need to be taken to protect subgrade
materials.All geotechnical recommendations shall be incorporated into the design plans.
4.A study shall be required and included in the TIR to verify downstream capacity for the overflow from the
reservoirs and prove the flows will have no environmental impacts.
5.Surface water system development fee (SDC)will be applicable.The current rate of SDC fee $0594 per
square foot of new impervious surface area,but not less than $1,350.00.
6.A Construction Stormwater General Permit from Department of Ecology will be required if grading and clearing
of the site exceeds one acre.A Stormwater Pollution Prevention Plan (SWPPP)is required for this site.
TRANSPORTATION/STREET
1.Transportation impact fees will apply to this project.The actual rate will be assessed at a later date.This fee
will be based on the amount of building area and its use per the ITE Manual.Payment of the transportation impact
fee is due at the time of issuance of the building permit.
2.Road Classification —Minor Arterial/North 12th Street
•Existing right of way width —approximately 60 ft.on North 12th Street with 2 travel lanes.
•Required ROW width Based on RMC 46060,North 12th St.requires 91 ft.
•ROW dedication needed —Approximately 15.50 feet on the north side of North 12th Street.
•11 ft.travel lanes,a 5 ft.bike lane,0.5 ft.curb and gutter,8 ft.sidewalk and 8 ft.planter strips will be required.
The applicant has submitted a modification for Right Of Way Dedication and street frontage improvements,which is
currently under review and staff is recommended approval.
3.Metro Bus requirements for the existing bus stop located in front of the site will require:Metro Bus Stop
#45130 Metro requests the inclusion of an ADA front door landing pad,read door lighting pads and a new shelter
footing to ensure adequate transit access and safety.
4.Paving and trench restoration will comply with the City’s Trench Restoration and Overlay Requirements.
