    What's New
    • 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.
      • Late May 2016, after two notices in the local paper are published, the formal 90-day comment period will begin. 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).
      • An interactive online FEMA Map is available that depicts the draft updated flood zones and the changes since the last effective Flood Insurance Rate Map (FIRM). You can also download maps from the FEMA websiteOnly 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 for FEMA approval  - all steps must completed PRIOR to when the maps become effective. 
    • Chester County Master Watershed Stewards - Underway!
      • 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: exa108@psu.edu 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.
