North Badger Creek

Elk Grove, CA

Mitigation for impacts to giant garter snake (GGS) for a Sacramento County development was through construction of marsh, upland, and wetland habitat at an off-site preserve. Foothill Associates performed a comprehensive restoration plan for the 25-acre mitigation site, including a channelized ¾-mile stretch of Badger Creek. In order to provide suitable habitat for GGS, while maintaining appropriate wetland functions, constructed wetlands were configured to support a combination of open water, perennial marsh, and seasonal marsh conditions. Wetland habitat was constructed to ensure that permanent, open water habitat will occur year-round. The design of the open water component of the restoration plan involved one inlet and one outlet to Badger Creek. The upper bank at both the inlet and outlet locations were breached to a width of 70 feet with standard construction equipment (excavator, backhoe). Embankments were graded and immediately replanted with native vegetation for slope stabilization. We created construction drawings and prepared and obtained regulatory agency permits needed for the restoration plan.
