The project site totals 1,512,110 square feet (34.7 acres) in area and is located within the Residential-1 (R-1) zone. Water samples would be pumped through the proposed intake line from the swimming area to the lifeguard/restroom building (Attachment A). In that building, an autoanalyzer would measure bacteria concentrations frequently throughout the day. This proposal would include the burying of a conduit, approximately three inches (3”) in diameter, that would house the water intake line. The conduit would be buried beneath the sandy area of the swimming beach and would tunnel under the sidewalk next to the lifeguard/restroom building. To bury the conduit under the beach, this project would include the digging of a trench that would be approximately six inches (6”) wide, 12-18 inches (12-18”) deep, and 90 feet (90’) long. The trench would be backfilled with the original beach sand. The proposed water line is anticipated to remain as part of a study that would likely last three (3) to five (5) years. At the end of the study, King County and Renton Parks may choose to continue using this water line as part of ongoing, long-term monitoring at the swimming beach. Whenever the water line needs to be removed, the process would be basically the same as the installation: a trench would be dug through the sandy beach to expose and remove the water line, and then the trench would be backfilled with the excavated sand. The project site is located along the shoreline of Lake Washington (Reach G), which is a Shoreline of the State and is within the Shoreline High Intensity Designation. According to City of Renton (COR) Maps, high seismic hazard areas, regulated slopes, moderate landslide hazard areas, Johns Creek, and the Well 5A Wellhead Protection Area Zone 2 are mapped on the project site.

Staff Comment: As stated in the submitted project narrative (Attachment B), the proposed project would have a value of less than $5,000 and would therefore qualify as an exemption from a Shoreline Substantial Development Permit. SHORELINE EXEMPTION FINDINGS: The proposed development is consistent with the following findings: i. Consistent with the policies of the Shoreline Management Act. ii. Consistent with the City of Renton Shoreline Master Program. Staff Comment: The proposed intake line for the collection of water samples at Gene Coulon Park would be consistent with the policies of the Shoreline Management Act and the City’s adopted Shoreline Master Program. Staff recommends, as a condition of approval, that when the water line is removed, the beach area should be restored to its original condition or better. *CONDITIONS OF APPROVAL: 1. When the water line is removed, the disturbed beach area shall be restored to its original condition or better.
