A public meeting is scheduled from 4:30 to 6:30 p.m. June 25, in council chambers at City Hall, 4035 Broadway, to discuss changes to the floodplain boundaries along West Water Run.
Following the 2008 map modernization for Franklin Countys Flood Insurance Rate Maps (FIRMs), questions arose regarding the accuracy of some of the measurements along West Water Run. To address those questions, the building division contracted EMH&T to perform a flood study on the waterway between Kmart at 2400 Stringtown Road and the limit of the existing detailed study upstream from Demorest Road.
New base flood elevations and floodplain boundaries were determined as part of the study and an application has been made to the Federal Emergency Management Agency (FEMA) to change the information on the existing FIRMs. This request is based on findings that the new study provides more accurate information about the potential for flooding at different sites along West Water Run.
As a result of the proposed changes to the FIRMs, some properties currently within the floodplain boundaries would be removed, while some properties now outside the boundaries would fall within the floodplain. Letters have been sent to property owners who would be affected by the changes, informing them of the study and inviting them to the public meeting.
Representatives of the building division and EMH&T will be available at the meeting to answer questions about the process and the effects of the new mapping on properties.
The proposed changes are under review by FEMA. If the data is accepted by FEMA, the new mapping would become effective six months after the approval date.
A preliminary map showing the proposed changes is available on the Grove City website, GroveCityOhio.gov.
