Kent,WA.98032-5895 DATE: Ju 2003 TO: r White and Kent City Council FROM: Do ickstrom, Public Works Director SUBJECT: Water Conservation Potential Assessment SUMMARY: As per our agreement for the Pipeline 5 Second Supply Project, we were required to conduct a Water Conservation Potential Assessment (CPA). The City of Kent has implemented water conservation programs and activities since 1993, targeting commercial, industrial and residential. The CPA examined potential for additional or expanded conservation measures which would help to attain 10%reduction in water use from improved water-use efficiency by year 2010. I i BUDGET IMPACT: No Unbudgeted Fiscal/Personnel Impact MOTION: Recommend Council amend the 2002 Water System Plan (Ordinance # 3606 adopted at the June 18, 2002 City Council Meeting) to include the Water Conservation Potential � Assessment. BACKGROUND: The Conservation Potential Assessment evaluated potential water savings and associated costs for conservation measures that can be taken between year 2003 and year 2010. These water conservation savings are in addition to those realized since our conservation program began in 1993. The CPA fulfills the requirements of the Memorandum of Agreement between partners in the Second Supply Project, Department of Health and Department of Ecology.

COMMUNITY DEVELOPMENT Mike H. Martin, Deputy Chief Administrative Officer PUBLIC WORKS DEPARTMENT Don E. Wickstrom, P.E. Public Works Director • KENT WASHINGTON Address: 220 Fourth Avenue S. Kent,WA 98032-5895 Date: June 26, 2003 To: Public Works Committee � From: Don Wickstrom if (1 Regarding: Proposed L.LD.: 111`h Ave Sanitary Sewers (SE 256`h Street to 850 feet north) The City received a petition for the installation of sanitary sewers in the vicinity of I I1`h Ave. S.E. and SE 2561h St. in the residential plat of Coates Addition as shown on the attached map. Subsequently, all property owners within the project area were contacted and there appears to be adequate support to proceed with the LLD, formation. The project area is inside the City limits and Kent's sewer service area. The City developed a proposal to service eleven unsewered lots. All other lots on this portion of 111"' Ave. S.E. already have sewer connections. The information including cost was given to the petitioner. The petitioner sent the information to the neighbors in the area and confirmed interest in the L.I.D. with new signatures on a new petition. Seven of the eleven lots (64%) signed the petition. These parcels are indicated on the map. The total L.I.D. assessment is estimated at $165,000. All lots are platted single family lots receiving one side sewer connection so all are assessed equally. The estimated assessment is $15,000 per lot. The project area consists an older residential plats (1965) developed with septic systems. Five of the eleven lots remain vacant needing sewer to be developed. It is not known how many existing septic systems are technically in a state of failure, however, we understand from the residence that there are septic problems in the area. One owner said his system is near total failure and needs frequent pumping of the septic tank. He is unable to get a permit to rebuild his drain field. Usually it is difficult to repair septic problems, especially on small lots such as these with limited space. Sanitary sewers are usually the most feasible, economical and long term method for addressing these problems, especially when numerous property owners in a neighborhood support sewer installation as is the case with this proposal. The Department of Public health has told us that the life expectancy of a septic system is twenty to thirty years depending on use and maintenance and that they are a short term disposal method until public sewers become available. The project area has greatly exceeded this time frame and the reports of failures substantiate that these systems are at or are near the end of their useful live. They also say that the cost of septic repairs may be as high as converting to public sewers. The latest state codes make septic repairs more difficult and expensive. The soil type within the project area is poorly rated for septic system use. According to the soil Conservation Service (US Dept. of Agriculture) Soil survey for King County, the soil type as mapped is rated severe limitation for septic drain fields. The soil series is designated as AgB (Alderwood gravelly _ sandy loam, 0 to 6% slopes). This soil exhibits very slow permeability below a depth of 24-40 inches and a seasonal high water table. Effluent and drainage move laterally over the imperious layers. Effluent may come to the surface in yards and in roadside ditches. Five of the eleven lots in the proposed L.I.D are vacant. Sanitary sewer is needed to make these lots developable. Without sewer, the owners carmot develop the lots or realize the full value of the property upon selling. There is interest in improving these lots with sewer. However, one owner of an undeveloped lot said she doesn't want the local improvement district. There are no City owned properties within the proposed project therefore no assessments to be paid by the City. However, the proposal is for the City to contribute $91,500 sewer utility funds. Nine of the twenty lots along the proposed sewer have already obtained service from a sewer east of the plat. Therefore, there are only 11 of the 20 lots remaining to share the cost of the proposed sewer. If all 20 lots were included, the estimated assessment would be approximately $15,000 per lot. The proposal is for the City to fund the costs in excess of the $15,000 per lot assessment. ACTION REQUESTED Recommend adoption of the Resolution of Intent setting a public hearing date on the formation of the L.I.D. for the 11 properties shown on the attached map.
