The SSCRPC recently completed it's annual "Floodplain Mailing" this September. The major sources of flooding in Sangamon County are the Sangamon River and the South Fork of the Sangamon River. However, many other creeks, as well as Lake Springfield, can experience major flooding events. A 5% to 15% discount on flood insurance is available on property in unincorporated Sangamon County because a Community Rating System rating of 7 was assigned by the Federal Emergency Management Agency based on prevention activities undertaken by the County. This mailing is one of those activities.
