WASTEWATER TREATMENT PLANT PROJECT
WWTP COST ESTIMATE
The Wastewater Treatment Plant (WWTP) facility improvements project cost estimate is $6.0 million. The City Engineer will refresh this estimate this fall after the biosolids component is complete – likely in November 2013.
WWTP ENVIRONMENTAL ASSESSMENT
Pacific Habitat Services, Tetra Tech and Otak awaits NMFS review of the TT memo on this issue to determine whether an informal or formal consultation will be required.
HEADWORKS PARSHALL FLUME & RELATED IMPROVEMENTS
Lyda Excavating completed the project the first week of July 2013. The construction improvement cost $275,000 – this is less than the engineers estimate by about $35,000.
BIOSOLIDS REMOVAL PLAN
The City Council and Public Works committee met to assess the Biosolids Removal Plan and the City Engineer’s plan for completing that task. The Public Works Committee recommended to the City Council that the biosolids removal was important and should be completed in 2013. Following the adoption of an emergency resolution last week the City Engineer and City Administrator initiated efforts to complete this task. The resolution requires approval of a Biosolids Removal Plan by DEQ – we estimate that the notice to proceed will be issued to the selected contractor before September 26, 2013. The City Engineer identified at least two firms that will be asked to submit proposals to dredge and process biosolids and to coordinate in the transfer of processed material into trucks. The biosolids will be land applied at a property that is on Clean Water Services DEQ approved site. The pricing for this process will firm up when we receive the bids from the dredging contractors, and we identify where in the Willamette Valley the trucks will need to haul to land apply.
The City Council and Public Works committee met to assess their risk tolerance for initiating the dike elevation project and determined that they would accept the public Works Committee recommendation to delay the project to a Spring 2014 start date. The City Engineer will work with our geotechnical engineer to pre approve one or more local site as a resource for aggregate, clay and fill dirt. This activity is important in our efforts to manage cost for haul time once the general contractor charged with dike elevation is selected.
HYPORHEIC DISCHARGE INFILTRATION WWTP PROJECT
The City Council and Public Works committee at a recent joint meeting discussed but did not form an opinion on the timing of the hyporheic discharge infiltration project. The discussion focused on whether to select a general contractor to act as the prime and have subcontractors or to select subcontractors for each discrete part of the project. The City Engineer will provide a technical memorandum to the Public Works Committee that discusses the options in more detail in August 2013.
OTHER PUBLIC WORKS ACTIVITY
WATER RATE UPDATE
OAWU met with City staff and shared their assessment of the water rate adjustment and made a two-year CPI rate adjustment. This will be shared with the Public Works Committee. This adjustment and any other recommendations that the PWC may make to the Water Fund budget (e.g. meter replacement program, reserve requirements, equipment replacement) will be reviewed as an entire package.
OPRD SPENCER PARK DEVELOPMENT
The COV Parks Committee will hold their August 2013 meeting at the new Spencer Park site to confirm the location of the planned new restroom and picnic shelter – to be located on a portion of the former middle school gravel. The Park Committee will establish rough markers for the selected contractor to use to establish the edge of new park improvement leaving at grade this proposed city improvement. The Parks Committee will also establish the way forward (designer or design build).
SPENCER PARK DEVELOPMENT OPTIONS
The District plans to secure a contractor in August 2013 for the Replacement Park Improvement Project at the old school campus which will entail taking the post demolition 11 acre parcel to final grade by layering and compacting soils, amending the top six inches of the soils, and seeding soil. The park project also includes a new baseball backstop and fencing to a coaches box.
OPRD MASTER PARK PLAN
MacKay and Sposito seek input from the public to assist in their park planning project. Survey will be posted on line and made available at local outlets in July. The survey process concludes on August 9th 2013. The City will try to wrap up this project by October 2013.
