Chester County Posts Final Draft Stormwater Standards

January 2012Articles In the Zone

On December 21, 2011, the Chester County Water Resources Authority published the Final Draft of its county-wide Act 167 Stormwater Ordinance Standards Matrix. The Authority has been conducting county-wide Act 167 stormwater planning with county municipalities for the past several years and has integrated its input into the final draft.

The county-wide Act 167 plan intends to cover all watersheds in Chester County that do not already have a PA Act 167 plan approved since 2005. The plan objective is to reduce future flooding impact and improve and protect water quality of the county’s streams. It also intends to assist municipalities in addressing stormwater management needs and certain NPDES MS4 requirements.

Phase I of the county-wide planning effort consisted of developing a set of draft stormwater ordinance provisions based on municipal input and feedback and confirmation that the Watersheds Plan fulfills the requirements of Act 167. This initial investigative phase was completed June 30, 2010.

The draft ordinance provisions and model ordinance were further developed and finalized during Phase II. Ultimately, after the completion of Phase II, all municipalities in the county will be required to adopt stormwater ordinance standards that are at least equivalent to the final minimum stormwater design standards in the county-wide 167 Plan.
