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.

Proposed pump station location – Easement along Girl Scout
Property
Sewer Connections made at time of project completion
Sewer fee charges start once property is connected to the
system
If presented “street design” approach is accepted, trees,
fences, etc. do not need to be removed. May need to
temporarily remove some fencing then put back.
Spring Lane walking path – will work with Streets Dept. for
best material
