The proposed project is the implementation of part of the Murrieta Creek Master Drainage Plan (MDP) adopted by the Riverside County Flood Control and Conservation District. It would connect an upstream flood control pipe northeast of Madison Avenue to existing drainage on the southwest side of Jefferson Avenue through a series of underground pipes and open, soft bottom, channels. There would also be a berm to control flooding across Jefferson Avenue that would be removed if and when flood control improvements are made to the adjacent property. The proposed configuration is a slight deviation from the general alignment conceptualized in the MDP as it optimizes the ability to develop commercial properties along the aligment in the future.
Approximately 49.917 acres would be disturbed for re-alignment of lines D and D-1. This area includes impacts to ~24 acres that are temporary due to construction activities as well as ~24 acres of permanent impacts due to permanent flood control improvements. It is anticipated that construction of the drainage improvements would require no fill dirt or rocks to be imported or exported from the site.
The proposed project is anticipated to start grading activities in early to mid 2010 and complete construction by mid to late 2010.
