CBI 2016 Wildlife Infrastructure Plan for SR-94

Type: report

Article abstract: This review prioritizes infrastructure improvements of 35 existing undercrossings inspected by wildlife experts in the field along 14.6 miles of SR-94 where the highway bisects conserved lands—particularly between the San Diego National Wildlife Refuge (SDNWR), where a box culvert has been designed specifically for this undercrossing, between Rancho Jamul Ecological Reserve (RJER) and Hollenbeck Canyon Wildlife Area (HCWA), and between Bureau of Land Management (BLM) lands and the Lawrence and Barbara Daley Preserve (LB Daley). In total, SR-94 crosses >10 miles of conserved lands with only three bridges—at the Sweetwater River, Dulzura Creek, and Campus Grove bridge in Dulzura. Following is a summary of improvements recommended for existing undercrossings and proposed new undercrossings, by segment, presented in this document.

Purpose: The purpose of this review is to (1) identify where improvements to existing infrastructure along 14.6 miles of SR-94 could improve connectivity in MU3 and decrease the potential for wildlife-vehicle collisions, (2) recommend wildlife movement monitoring to identify where new crossings are needed on SR-94 and other roads, and (3) identify where additional conservation would enhance the integrity of South County linkages.
