Arroyo de la Laguna Mitigation
Hanford performs implementation of the Habitat Mitigation and Monitoring Plan within 6.81 acres of designated Mitigation Area along the Arroyo de la Laguna.
This is done via several steps: invasive species management across the entirety of the site, with the objective being to reduce non-native plant populations both before and after planting efforts, installation of roughly 4,200 plants, willow poles, compost, wood chip mulch, browse protection caging throughout the riparian mitigation site, and lastly installation of an on-site irrigation system, consisting of PVC pipe, lateral poly drip tube lines, valves, and on-site holding tanks.
Hanford performs ongoing annual maintenance for six years after implementation. Maintenance includes supplemental watering through plant establishment during the dry season, twice annual mowing, direct removal of invasives, and replanting depending upon monitoring results.
