    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 February 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).
      • Download maps from the FEMA website. Additionally, 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). Only some flood zones in Chester County were revised. Consult the Municipal Index (link above).
      • FEMA anticipates that the mapping will become effective Spring of 2017. All municipalities in the NFIP program will need to determine if they must revise their floodplain ordinance, and if so updates must be adopted PRIOR to when the maps become effective. More information regarding these requirements will be provided at the FEMA follow-up meeting in the Spring of 2016.
    • Chester County Master Watershed Stewards - Seeking Volunteers
      • Volunteers with a strong commitment to service are needed to help improve the health of our streams and natural resources. Volunteers will be provided with extensive once-a-week training and upon completion must pass a final exam. Within the first year after the classroom study, apprentices are required to volunteer 50 hours in the community. This program is a project of the Penn State Chester County Master Watershed Stewards and the Chester County Conservation District. 
      • For more information, please read the latest press release. To obtain an application (due by February 1, 2016), please send an email to: exa108@psu.edu with the subject line "2016 Master Watershed Training".
    • 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
      • We are seeking volunteers to participate in the Chester County 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. A 3-inch diameter plastic rain gage is provided at no cost to the volunteers. The volunteer is responsible for mounting the rain gage to a post or other suitable location at their home. An ideal volunteer is committed to recording - on a daily basis - consistent and accurate measurements, and willing to participate as a volunteer for years. If you are interested in finding out more about the Network or to become a volunteer, please contact the CCWRA at 610-344-5400.
