Stormwater Management Plan

National and State stormwater regulations require certain small communities to obtain a National Pollutant Discharge Elimination System (NPDES) permit. The City of Liberty is affected by the Phase II Stormwater regulations. The permit requires that communities with regulated Municipal Separate Storm Sewer Systems (MS4s) have a Stormwater management program in place. You may view the proposed Stormwater Management Plan below.

You are invited to submit any comments on the plan to the Engineering Division by email.
