SCOPE OF SERVICES RELATED TO
PHASE 1 DESIGN SERVICES
FOR THE
PORT ANGELES CSO IMPROVEMENT PROGRAM
Task 16's Scope of Work for engineering services to be provided by Brown and Caldwell
(BC) is for the development of to constructing storage to mitigate Tribe
wastewater flows during City CSO events.
This task is further described as follows:
Task 16 (Evaluation of Alternatives):
BC will develop proposed projects for diversion of storm flows frorn connected areas within
the. City of Port Angeles that will produce comparable effect as the proposed Elwha storage
tank. We will also estimate the cost to implement those projects. The BC effort will include
collaboration with the City to identify candidate areas and estimate the impact of their
disconnectionfrom the City's combined sewers in terms of the approved. CSO control
program through modeling.
The system model that developed the CSO compliance strategy will be used to determine
the volume that has to be removed from the system (based on the City and Tribe agreement
that overflow volume and frequency will not be increased) and to measure the effect of
removing specific surface areas draining into the CSO system. Essentially, the surface area
that has to be removed will be the storage volume divided by the rainfall depth of CSO
compliance- critical rain events identified from the modeling.
Working with the City and their GIS databases, we will identify and compute the surface
areas that could be removed by intercepting given, catch basins. The identified catch basins
will be evaluated for collection and discharge to an available and acceptable storm water
conveyance feature for discharge, We have not included any field time in Port Angeles but
have assumed the City will confirm and help qualify estimated connected areas draining to
selected catch, basins.
Preliminary sizing of new gravity conveyance piping will be laid out and estimates of
construction and project costs will be estimated for completing the disconnection of as
many as 4 separate areas. A technical memorandum will be produced describing the
methodology, findings and results including diagrams of proposed flow reduction /area
disconnection projects.
BC will begin work within 2 weeks of notice to proceed and completing the
identification of flow reduction projects within 4 weeks (assuming timely input from the
City).
