Project Overview


WEBB has the expertise to implement measures required by legislative bodies and regulatory agencies, controlling every facet of drainage solutions and stormwater runoff management.

The completion of Line 43 and Lateral 43-A was an important component to the flood protection Eagle Canyon Dam provides to the City of Cathedral City. This master plan facility was the main link from the dam to the West Cathedral Canyon Channel.

 

The criteria used to establish facility type and location for the Master Plan was developed in 1982 and since then, several changes have occurred in the area including the construction of new businesses, the removal of other businesses, the re-designation of Highway 111 from a state highway to a local highway, and updates to the rainfall design values.

Key Issues & Challenges


Mitigating Impact to Local Businesses

Collaboratively partnering with the City was crucial to the success of this project. In order to do this, WEBB met with the City Engineer and the City Redevelopment Director on a regular basis to determine the critical success factors for the City. Impacts to the local businesses were of key importance to the City.

To minimize those impacts, WEBB designed a precast RCB system that substantially reduced construction related impacts to local business. WEBB identified and coordinated the relocation of multiple existing utilities in Highway 111. The design and construction of this mile long drainage system has significantly improved the flooding conditions in Cathedral City.
