Public Works Department-Gregg Zimmerman,P.E.,Administrator November 14, 2013 Mr. Mark Gropper, Executive Director Renton Housing Authority PO Box 2316, 2900 NE 10th Street Renton, WA 98056-0316 RE: PROPOSED FINANCIAL AGREEMENT FOR THE USE OF THE SUNSET TERRACE REGIONAL STORMWATER FACILITY FOR ON-SITE MITIGATION OF THE PIHA SITE Dear Mr. Gropper: Per the FY 2012 Statewide Stormwater Grant Agreement No. G1200544 between the City and the Department of Ecology, the City is required to design and construct a facility that will infiltrate three-acres of impervious surface. The cost of designing and constructing a facility to mitigate for any additional areas needs to be covered by the private property owner or entity of which areas are being mitigated for. The City of Renton Surface Water Utility has completed a preliminary cost analysis to estimate Renton Housing Authority's (RHA) share of the cost for use of the Sunset Terrace Regional Stormwater Facility for stormwater mitigation for the on-site improvements on the PIHA site. For this exercise, we decided to do a proportional cost (including design and construction) based on tributary impervious area draining to the regional facility. Per the information provided by SvR Design Company on November 1, 2013, approximately 0.75 acres of impervious area are proposed to be constructed on the PIHA site. This will result in a 25% increase of tributary area to the Sunset Terrace Regional Stormwater Facility. The City is currently under contract with CH2MHILL (GAC-13-021) for the design of the facility. Total design cost for a regional facility that will provide mitigation for three- acres of impervious is $179,003. The estimated cost for additional engineering efforts to accommodate additional impervious areas from the PIHA site is $44,750 (25%of current design contract). The RHA will be responsible for the actual additional design cost to be determined as part of a contract addendum with CH2MHILL. We anticipate that the actual cost will be less than this estimated amount. Renton City Hall • 1055 South Grady Way• Renton,Washington 98057 • rentonwa.gov Mr.Gropper November 14,2013 Page 2 of 2 A pre-design report with approximately 15% sizing of the Sunset Terrace Regional Stormwater Facility was completed in 2012. Appendix E of the report includes a cost estimate of the regional facility estimated at a range between $597,000 and $900,000 for mitigation of three-acres of impervious). Construction cost for mitigation of additional mitigation of 0.75 acres of impervious is estimated at a range between $149,250 and $225,000 (25% of cost estimated in pre-design report for a facility mitigating for three-acres of impervious). The actual construction cost will be based on final construction contract amount at time of final pay estimate. Based on the explanation above, RHA's share of the cost for the use of the Regional Stormwater Facility for mitigation of the improvements constructed in the PIHA site is estimated to be between $194,000 and $269,750. The Department of Ecology indicated that we will need to track the eligible and ineligible grant cost for design and construction separately. The Department of Ecology will also need to review and approve the cost share agreement between the City and the Renton Housing Authority. To move forward with the design of the Sunset Terrace Regional Stormwater Facility, we will need a letter confirming RHA's intent to use the Sunset Terrace Regional Stormwater Facility for mitigation of the required on-site improvements of the PIHA site. If you have any questions, please contact Hebe Bernardo, Surface Water Utility Engineer, at 425-430-7264 or by email at hbernardo@rentonwa.gov or me at 425-430-7248 or by email at rstraka@rentonwa.gov. Thank you for your efforts in assisting the City in the design of the Sunset Terrace Regional Stormwater Facility. We look forward to working with you and RHA's staff in the coming months on this important project. Sincerely, Ronald J.

This memo assumes similar sub surface conditions for this preliminary analysis. Site specific geotechnical investigations will be required for design. Overall Piha Site Stormwater • Per the Pre-application Meeting Minutes, the Project is subject to the Peak Rate Flow Control Standard-Matching Existing. • Per Section 1.2.3 of the City of Renton Amendments to the 2009 King County Stormwater Design Manual(COR),the Project is not eligible for any flow control exemptions. • Per COR Sections 1.2.3.3 and 1.2.8,Flow control BMPs and water quality treatment are both required. F:\13\13015 Sunset Terrace\Design\Storm\PihaStormMemo_Jess.doc Stormwater Memorandum ' November 1,2013 Page 2 of 2 On-Site Flow Control,Flow Control BMWs and Water Quality • Flow Control Options include: o Flow control may be achieved by installing a traditional detention system. Based on KCRTS modeling, a 7,500 cubic feet of storage would be required to meet flow control requirements. This could be sized in a 43'x43'x4' (LxWxH)vault. o Flow control may also be achieved by installing a combination of low impact development (LID) to the fullest extent allowed by site constraints, likely in conjunction with a traditional detention system. o Meeting the Project's flow control requirements exclusively with LID does not appear feasible given the level of proposed impervious surface coverage needing mitigation,and setbacks. • For the on-site portion of the Project, the proposed 8,600 square feet of pollution generating parking lot/driveway is the only area that would require runoff treatment. Treatment requirements may be met through the use of Catchbasin Stormfilters or infiltrative BMPs if setbacks and soil property design conditions are met. Right of Way Flow Control, Stormwater BMPs and Water Quality • 425 cubic feet of storage volume would be required in order to meet the Project's flow control requirements with a vault. A 14'x8'x4' (LxWxH)vault is one potential configuration that would meet these requirements. • Pervious sidewalk paving and/or raingardens in the planter strip appear to be the most feasible options for meeting right-of-way flow control BMP requirements. • Water quality treatment is required for the pollution generating portions of the ROW improvements (new roadway surfaces). • If raingardens are utilized in the planter strip,they could provide both flow control and water quality treatment for the roadway surface. Runoff not infiltrated can be treated using a Catchbasin Stormfilter or another approved shallow treatment facility.

The cost of designing and constructing a facility to mitigate for any additional areas needs to be covered by the private property owner or entity of which areas are being mitigated for. The City of Renton Surface Water Utility has completed a preliminary cost analysis to estimate Renton Housing Authority's (RHA) share of the cost for use of the Sunset Terrace Regional Stormwater Facility for stormwater mitigation for the on-site improvements on the PIHA site. For this exercise, we decided to do a proportional cost (including design and construction) based ih tributary impervious area draining to the regional facility. Ofx Per the information provided by SvR Design Company on November 1, 2013, approximately 0.75 acres of impervious area are proposed to be constructed on the PIHA site. This will result in a 25% increase of tributary area to the Sunset Terrace Regional Stormwater Facility. The City is currently under contract with CH2MHILL (GAC-13-021) for the design of the facility. Total design cost for a regional facility that will provide mitigation for three- acres of impervious is $179,003. The estimated cost for additional engineering efforts to accommodate additional impervious areas from the PIHA site is $44,750 (25% of current design contract). The RHA will be responsible for the actual additional design cost to be determined as part of a contract addendum with CH2MHILL. We anticipate that the actual cost will be less than this estimated amount. Mr.Gropper November 13,2013 Page 2 of 2 A pre-design report with approximately 15% sizing of the Sunset Terrace Regional Stormwater Facility was completed in 2012. Appendix E of the report includes a cost estimate of the regional facility estimated at a range between $547,000 and $900,000 (for mitigation of three-acres of impervious). Construction cost for mitigation of additional mitigation of 0.75 acres of impervious is estimated at a range between $149,250 and $225,000 (25% of cost estimated in pre-design report for a facility mitigating for three-acres of impervious). The actual construction cost will be based on final construction contract amount at time ofdFrfi ' n. Based on the explanation above, RHA's share of the cost for the use of the Regional Stormwater Facility for mitigation of the improvements constructed in the PIHA site is estimated to be between $194,000 and $269,750. The Department of Ecology indicated that we will need to track the eligible and ineligible grant cost for design and construction separately. The Department of Ecology will eview and approve the cost share agreement between the City and the Renton Housikg Authority. To move forward with the design of the Sunset Terrace Regional Stormwater Facility, we will need a letter confirming RHA's intent to use the Sunset Terrace Regional Stormwater Facility for mitigation of the required on-site improvements of the PIHA site. If you have any questions, please contact Hebe Bernardo, Surface Water Utility Engineer, at 425-430-7264 or by email at hbernardo@rentonwa.gov or me at 425-430-7248 or by email at rstraka@rentonwa.gov.

Grady Way 15th Floor I Renton, WA 98057 RE: PROPOSED FINANCIAL AGREEMENT FOR THE USE OF THE SUNSET TERRACE REGIONAL STORMWATER FACILITY FOR ON-SITE MITIGATION OF THE PIRA SITE Dear Mr. Straka, Thank you,for the careful evaluation of the option for RHA to consider sharing in the cost and use of the Sunset Terrace Regional Stormwater Facility for the on-site mitigation of flow from the"Piha"site. - Your November 14,2013 analysis suggests that.RHA's share of the cost is between$194,000 and$269,750 for the expansion necessary to connect any future development of the Piha site to the regional facility. As discussed, there is yet to be a projected fully designed or funded on the Piha lot; for that reason RHA declines to participate financially in the subject stormwater facility. I hereby concur with your recommendation that the City proceed with the Sunset Terrace Regional Stormwater facility design to not provide flow control for runoff from the RHA PIRA site. The Sunset Terrace Regional Stormwater facility would therefore not be designed to provide flow control. for the runoff from the RHA PIHA site. Thank you, again,:for enabling your Renton Housing Authority to explore its options as together we aspire to meet the affordable housing needs of our great city.
