Title
Personal Services Agreement with RH2 Engineering for the Trillium Park Drive Landslide Mitigation Alternatives Analysis
Body
RECOMMENDED ACTION (Motion):
Authorize the City Manager to execute the Personal Services Agreement (PSA) with RH2 Engineering for the Trillium Park Drive Landslide Mitigation Alternatives Analysis (CI 17-010).
BACKGROUND:
In February 2017, following a period of heavy rainfall, Trillium Park Drive experienced significant earth movement between Canyon Court and Swordfern Court that led to a waterline separation and movement and deformation of a sanitary sewer line. The waterline within the slide zone was abandoned, however, the sanitary sewer line remains in service. Other utilities within the slide zone, including power and natural gas, have been rerouted and the street has been closed to vehicular traffic.
In October 2017, city staff met with representatives of RH2 Engineering, GRI Geotechnical and Environmental Consultants (GRI), and Compass Surveying to discuss development of a scope of work for the Trillium Park Drive Landslide Mitigation Alternatives Analysis project (CI 17-010). In November 2017, staff reviewed and approved the proposal submitted by RH2 Engineering. RH2 Engineering will be the lead consultant on the project with GRI and Compass Surveying being subconsultants.
BUDGET IMPACT:
Amount: $78,571
FY(s): 2017/18
Funding Source: Water Fund, Sewer Fund, Storm Fund, and Transportation Fund
