The 20.2-acre O’Neill/Mullin site is a commercial development in the southern end of Napa County. Though the relatively new Corps regulations lean heavily towards mitigating project impacts at mitigation banks, on-site restoration can still work under certain circumstances. However, the Corps may look at these projects with increased scrutiny compared to the past. We developed a mitigation plan for the site and worked with the Corps staff to eliminate any potential concerns as a result of that increased scrutiny. The resulting plan was one that both the client and Corps staff approved and resulted in a smooth permitting process.
