Projects
Below is a listing of currently scheduled projects for Oak Lodge Sanitary District.
Surface Water Mangement Projects
Trolley Trail Drainage Improvements
As part of the North Clackamas Park and Recreation District Trolley Trail Project, the Oak Lodge Sanitary District is upgrading a variety of regional drainage facilities associated with the trail. The construction project includes improvements such as storm pipes, upgrading culverts, grading and other stormwater facilities. The District is contributing an estimated $100,000 towards construction of these regional improvements beyond the scope of the trail project. Construction will begin in the spring of 2011.
NCPRD Park Improvements
The District and the North Clackamas Park and Recreation District are jointly funding riparian improvements to Stringfield, Risely and Rivervilla Parks. These improvements include removal of invasive species and planting of native plants in the parks. These improvements allow the District to improve bacteria removal and lower water temperatures. The park improvements will be implemented with contractors, staff resources and volunteers. The District will spend $67,000 on these improvements in Fiscal Years 2011 and 2012.
Park Avenue Station
In a partnership with Tri-Met and the North Clackamas Parks and Recreation District the District is participating in adding natural areas to the Park Avenue Light Rail Station. This project involves adding naturescaping in the area of the Park Avenue Station and has been awarded a Nature in the Neighborhoods Grant. The District’s share of this $1.5 million project ($400,000 towards offsite naturescaping) is $60,000 with improvements constructed in Fiscal Year 2013/2014.
Walta Vista Culvert
Boardman Creek crosses under River Road in an ancient arch culvert. This culvert impedes fish passage, creates flooding, and deteriorates water quality throughout the Boardman Basin. The District’s recent Watershed Strategic Plan set a priority on this culvert replacement. Both the Clackamas County Department of Transportation and Development and the District have interest in replacing this obstruction with a $1.6 million bridge. Preliminary Engineering will begin in Fiscal Year 2012 with the ultimate project construction schedule depending on funding.
Ordinance Revisions
The District’s surface water ordinances have not been updated since 2000. The District’s Surface Water Strategic Plan recommends updating these ordinances immediately. The revised ordinances will be expanded to include new development requirements, erosion control, public facility requirements, systems development charges and water quality regulations. The District will spend $100,000 to upgrade the ordinances in Fiscal Years 2011 and 2012.
Naef Road Culvert Removal
South Boardman Creek passes under Naef Road in a 60 inch culvert. Shortening this culvert from 220 feet to 60 feet opens up a major stream segment by the Stringfield Park. Shortening this culvert will increase riparian area, increase shade, improve fish passage and decrease bacteria in the creek. This $100,000 project depends on obtaining a private easement and will take place over two years.
DEQ MS4 Projects
In 2011, DEQ issued a new MS4 discharge permit to the District. This permit included a number of requirements including a retrofit analysis, a hydromodification study, a benchmarking study and a biological assessment of the District’s streams. The DEQ also requires the District to begin retrofitting existing drainage systems with water quality facilities. The District budgets these projects $150,000 over the next three fiscal years.
Worthington Lane Drainage Improvements
Worthington Lane lacks drainage facilities and experiences flooding. Correcting this problem involves installing 200 feet of pipe, catch basins, and several manholes. This project is estimated at $50,000 and is scheduled for Fiscal Year 2012.
Sanitary Sewer Projects
Sanitary Sewer System Master Plan
This project involves the creation of a new santiary sewer system master plan guiding OLSD future investment in the wastewater treatment plant. The OLSD treatment plant meets the current requirements, but the facility faces many future challenges, including a chlorine system that must be upgraded to current safety standards, a 60's era biological system with inadequate capacity to meet modern standards, and a highly-eroded gravity thickener. Additionally, the District faces new environmental regulations affecting the Willamette River, which may require renovation or improvements beyond modernization of the treatment plant's aging infrastructure. The master plan will identify the facility needs, develop solutions, and establish a correction plan. The OLSD Board of Directors will review and approve any master plan efforts.
Plant Renovation Design Service Phase 1
Money budgeted to begin implementing the improvements recommended through the Master Plan, pending its approval and creation.
