The new facility would be owned by the City of Lake Oswego and operated by EFWP for 30 years. The new facility is being designed to meet new regulations within a smaller footprint on property located adjacent to the current treatment plant (at 99, 101 and 113 Foothills Road: see attached preliminary site plan). The proposed site of the new facility is located on properties that are not currently owned by the City. Property negotiations and acquisitions are beginning with the property owners over the coming months. The new facility will provide wastewater treatment for the same service area as the existing treatment plant, but with flows projected out 30 years, and meeting higher treatment requirements, as well as fitting on a smaller footprint. Due to infiltration and inflow during the wet weather season, the facility will be designed to treat a large fluctuation in flows and loadings. Visually, the new facility will be designed to blend into a mixed-use community avoiding industrial-looking characteristics as much as possible. The facility will incorporate odor and noise control to be a good neighbor. A conceptual architectural massing study is attached, showing different views of the treatment facility. EFWP performed a site survey that identified existing trees with trunks 6 inches in diameter or larger. Thirty-nine (39) trees have been identified as being on the property requiring removal to accommodate the new facility layout and construction activities. The proposed Tree Protection Plan figure is attached. The three properties collectively have a significant elevation change from the lower east side to the higher west side. The elevation change will be utilized in the treatment process by allowing much of the flow in the plant to move by gravity, eliminating many pumps often required in facilities to move water from one process to the next. The elevation change will also be utilized to visually blend the volume required for the process basins, as the deck will be level with the higher west-side ground. The basins will be partially buried even at the lower east-side elevation to minimize the visibility to the public. The facility will consist of the following main buildings and process structures: • Administration building – to be located on the southwest side of the property • Treatment Process basins and buildings – to be located in the center of property; buildings include: o Headworks Building o Filter/UV Building o Blower Building o Electrical Building • Odor Control – to be located on top of the process basins, likely hidden by a screen wall or blended into the Headworks Building located behind it • Maintenance Building – to be located near the back of the facility on the upper level The administration building will be the focal point of the treatment facility from Foothills Road. A preliminary floor plan of the Administration building is included with this application. Parking for the public will be provided on the west side of the Administration building, next to the main entrance, which EPCOR FOOTHILLS WATER PARTNERS | City of Lake Oswego Wastewater Treatment Facility P3 Pre-Application Form Attachment 2 | Page opens into the Reception/Admin area. Additional parking will be provided on the north side, typically for use by facility staff. The Headworks, Blower, and Electrical Buildings will be built on top of the process basins with finished floors level with the west side grade. They will have access doors on the west side. The Filter/UV Building will be accessible from the north side of the building at the lower ground level. The existing influent and effluent pipelines that feed raw wastewater and discharge treated effluent from the existing plant will be modified as required to reroute flows to and from the new treatment facility. A Site Plan showing the influent and effluent piping modifications at the facility is attached highlighting the new pipelines and how they are integrated into the existing influent and effluent piping systems for the new facility. Influent sewers need to be redirected to the new influent pump station at the new facility. Part of the modifications include a temporary sewer line to maintain flow to the existing treatment plant while constructing key elements of the new facility prior to connecting into the new facility. The existing effluent pipeline discharges treated effluent to the river through the existing outfall piping and diffusers. The new facility will utilize the existing outfall while extending and upsizing the upstream effluent piping from the new facility to the connection point with the existing line. The attached exhibit, drawing C-1, shows the stormwater drainage system concept for the new WWTF. The exhibit shows three color-coded storm drain systems: the “main” storm line (purple) that can become pressurized when the Willamette River is high, local gravity-flow drainage to Pump Station “A” (map label #1; orange), and on-site drainage (red). Existing and proposed pipes are drawn with dashed and solid lines, respectively. Features discussed below are numbered on the exhibit. Stormwater from the facility will either be managed by the WWTF or drain to the City’s existing 48-inch stormwater main that discharges to Tryon Creek. The facility will meet City code requirements to treat its stormwater quality and quantity. It is not feasible to fully infiltrate either the 10-year or water quality design storms (3.2 and 1.0 inches rainfall in 24 hours, respectively) because of shallow groundwater and bedrock. Therefore, different areas of the facility will be managed and treated as follows: • Runoff from most of the facility, about 4.5 acres, including all building roofs and most of the west, north, and east driveways will be collected by the on-site drainage system (red) and pumped (map label #2) to the WWTF, pass through the tertiary treatment filters, and be discharged through the effluent line direct to the existing outfall into the Willamette River. Further treatment of this stormwater is not required. However, overflow in excess of the 10-year design storm will be piped north to the local drainage system and Pump Station “A” (map label #1). • The southern edge of the property, about 0.5 impervious acres and 0.5 pervious acres adjacent to Foothills Road, including a proposed 6-foot sidewalk and the north half of Foothills Road, will drain to an ~185-foot x ~8-foot planter (map label #3; green on the exhibit). The outflow will drain north through a new Local System line (map label #4) to Pump Station “A” (map label #1). • Offsite runoff flowing down the slope west of the site will be conveyed in open drainage swale (green on the exhibit) around the site to the existing north stormwater basin (map label #5). Stormwater treatment is not required for this flow. The eastern, lower-elevation portion of the site is in the City’s Flood Management Area (FMA) where additional requirements apply which will be addressed by the following: EPCOR FOOTHILLS WATER PARTNERS | City of Lake Oswego Wastewater Treatment Facility P3 Pre-Application Form Attachment 3 | Page • Habitable floors and electrical and mechanical equipment will be at an elevation of at least 37.2 feet (Lake Oswego Datum, which is the National Vertical Datum of 1929 [NGVD29]) to satisfy the requirement of being at least 1.0 foot above the February 1996 flood crest elevation, which was 36.2 feet just upstream. • Fill will be placed to raise a portion of the properties to a level above the base flood elevation (BFE, the 100-year flood elevation, which in this area is 33.95 feet NGVD29) mapped by the Federal Emergency Management Agency (FEMA) in the Flood Insurance Study of Clackamas County (including Lake Oswego). City code requires that fill be balanced by offsetting excavation for areas below the BFE unless the area is subject to a Letter of Map Revision Based on Fill (LOMR-F) from FEMA. A conditional LOMR-F (CLOMR-F) is planned to be obtained from FEMA for a portion of the properties to be filled above the BFE. (A LOMR-F will be obtained after construction is complete.) The CLOMR-F will include documentation of compliance with the Endangered Species Act (ESA). Outside the area subject to the CLOMR-F, fill will be offset by cut, expected to be east of the fill wall, this will need to be coordinated with the City. Additional details of the proposed new facility will be refined during the forthcoming design stages, including feedback from the neighborhood meeting and Development Review process.
