Title
Personal Services Agreement Amendment No. 2 with RH2 Engineering, Inc. for the Hazelwood Drive Sanitary Sewer Moratorium Project
Body
RECOMMENDED ACTION (Motion):
Authorize the City Manager to execute Contract Amendment #2 with RH2 Engineering, Inc. (RH2) in the amount of $68,496.00, to continue developing the engineering design for the Hazelwood Drive Sanitary Sewer Moratorium Project.
BACKGROUND:
The City of Oregon City's Sanitary Sewer Master Plan (SSMP) became effective November 1, 2014. The Hazelwood Drive basin was one of the moratorium areas identified for development restriction until sewer system improvements were made. Completing construction of this sewer project will allow the Hazelwood Drive Sewer Moratorium to be lifted. Hazelwood is the last moratorium area currently enforced under the Public Facilities Strategy, which expires October 1, 2018. It is the City’s goal to have serviceable sewer improvements in place to lift the Public Facilities Strategy prior to October 1, 2018.
Initial Personal Services Agreement (PSA); Phase I - Alternative Analysis and Preliminary Design
The City negotiated a fee proposal with RH2 Engineering Inc. for preliminary design services including surveying, video inspection of the sewer pipes, and evaluation of alternative construction methods on April 5, 2017. The preliminary design phase, which is nearly complete, will take the project to approximately a 30% level of design for much of the project and construction alternative recommendations in the more complicated alignment areas. It was anticipated when initially scoped that once a design alternative was chosen for the more complicated alignment areas, a scope for the final design documents would be submitted for approval.
Portions of this project are complicated by its alignment through private back yards and its proximity to Coffee Creek. During the preliminary design process, surveyed elevations were confirmed for a refined hydraulic model to verify the...
