The document summarizes a public meeting about a flood relief project for Hendren Street and Spring Lane. Residents confirmed that flooding and failed septic systems are issues. Samples were provided of flooding on Hendren Street and Spring Lane. A conclusion was that a stormwater-sanitary separate system is needed. The concept involves PWD installing separate stormwater and sanitary sewer mains with homeowners connecting laterals. Sections of the proposed system were presented along with estimated homeowner costs of $15,000-300 per foot for connecting laterals. Previous questions from residents were also addressed.
