Building/PROPERTY Additions
If your property is served by a septic system, prior to construction of any new additions on your property, including building additions, installation of pools, decks, patios, garages, etc., a B100a Review must be completed. In addition to proposals for additions, B100a applications are also used for building conversions (i.e. winterizing a seasonal home, converting an open porch into an all-season room) and property lot line splits.

- Plot plan showing existing buildings/structures on the property
- Location of proposed addition/structure
- Location of existing septic system
