- Interactive Online Water Resources Mapping Tools Available
- The Online Water Maps Gallery provides “self-serve” maps of Chester County’s streams and lakes, watersheds, protected water uses, impairments/pollutants (2014), FEMA floodplains, soils, Urbanized Areas (2000 and 2010), etc. Both PDF maps and interactive map tools are provided, as are links for available GIS data files.
- New Preliminary FEMA Floodplain Mapping Available
- Preliminary issuance of FEMA updated floodplain mapping (portions of Chester County) and updated map products (all of Chester County) was released December 2015.
- One June 1, 2016, the formal 90-day comment period began. All comments for the updated floodplain mapping must be submitted in writing during this period. To determine if your municipality has any draft revised floodplains and should therefore consider submitting comments, please consult the Municipal Index (9/11/15).
- The preliminary map changes are now available again via an interactive online FEMA Map. The previous interactive map was taken down and a permanent replacement for the interactive map is still under development. The current interactive map depicts the changes of the preliminary floodplain boundaries as compared to the currently enforced FEMA floodplain maps.
- You can also download preliminary static maps from the FEMA Map Service Center website (search by address and then click on "show all products"). You will also find the FIS and database files . Only some flood zones in Chester County were revised. Consult the Municipal Index (link above).
- FEMA anticipates that the mapping will become effective June 2017. All municipalities in the NFIP program must revise their floodplain ordinance, submit for PA DCED approval, adopt it, and then submit to PA DCED for final FEMA approval - all steps must completed PRIOR to when the maps become effective. Municipalities will work closely with one-on-one assistance from Leslie Rhoads from PA DCED to ensure their ordinance is compliant. Leslie's contact information: email (highly preferred) FloodplainUpdate@gmail.com or (717) 516 -1630.
- Contact Dani-Ella Betz at 610-344-5400 or firstname.lastname@example.org with any general questions.
- Chester County property owners should consult the preliminary FEMA maps to understand how the mapping of the FEMA floodplains may change. Property owners who may be newly designated in the floodplain may be eligible to receive a discount on their new policy, if purchased prior to the maps going final in 2017.
- Please consult the fact sheet for more information and the tentative timeline.
- The final PA DEP MS4 Permit was published on June 4, 2016 and will become effective March 16, 2018. Click here for more information.
- Chester County Master Watershed Stewards 2016 - First Graduating Class!
- This brand new program is a project of the Penn State Chester County Master Watershed Stewards and the Chester County Conservation District and serves to provide local volunteers with extensive once-a-week training. Upon completion, apprentices are required to volunteer 50 hours in the community. If you have a volunteer opportunity that you would like to promote, please contact Liz Alakszay: email@example.com with the subject line "Master Watershed Volunteer Opportunity".
- Today’s Water Levels for Chester County
- A visual snapshot of current precipitation, groundwater and streamflow conditions for Chester County is presented through a set of color graphs and maps, with links to additional online webpages for more detailed information.
- Volunteer Opportunity: Participate in the Volunteer Rainfall Observer Network
- Volunteers are responsible for taking readings of a rain gage daily and after significant precipitation events, manually recording the readings, and submitting the log on a monthly basis by email or postal mail. CCWRA compiles the data for analysis, and the updated results are posted on the CCWRA website. The volunteer is committed to recording - on a daily basis - accurate measurements, and able to consistently participate for years. If you would like to learn more, please contact us at 610-344-5400.
