Proposed Drainage improvements and Restoration Activities at the Rancho Mission Viejo Riding Park
Document Type
MND - Mitigated Negative Declaration
Present Land Use
Open Space Recreation (OSR) / Natural Open Space (NOS)
Document Description
The proposed Project consists of three principal components including: 1) removal of an existing Arizona Crossing (i.e., low-water bridge) across San Juan Creek; 2) streambank restoration along the Riding Park's border with the eastern bank of the creek; and 3) installation of a stormwater capture and treatment system to prevent the incidental discharge of stormwater pollutants. The City is undertaking the proposed Project to restore the natural conditions of San Juan Creek, protect the creek from potential incidental discharge of stormwater pollutants, and convey annual flood events at the Riding Park, while also restoring wetland habitat functions and values and surface water features that are under the jurisdiction of the U.S. Army Corps of Engineers (USAGE), San Diego Regional Water Quality Control Board (RWQCB), and California Department of Fish and Wildlife (CDFW).
