Article 41 Wastewater Planning Capacity Study Finance Committee Presentation To determine whether the Town will vote to adopt a resolution supporting the Town Manager’s allocation of $142,000, or any other sum, of Sewer Improvement Funds to investigate wastewater treatment and capacity management alternatives, including continued conservation measures, to accommodate wastewater flows above and beyond those flows necessary to meet existing requirements resulting from development and re-development under current zoning in a range between 320,000 to 600,000 gallons per day, which represents projected wastewater flows associated with objectives referenced in the Comprehensive Long Range Plan and Planned Production Housing Plan and quantified in the Wastewater Planning Task Force Report dated December 2008, and furthermore request that the Wastewater Planning Task Force return to a future Town Meeting to present recommended alternatives, including any requests for debt authorizations required to implement such wastewater treatment capacity alternatives, or take any other action relative thereto.

Article 41 Wastewater Planning Capacity Study Background Comprehensive Wastewater Management Plan (Received Town Meeting Approval in 2003 Town Meeting Article 36) Recommended Sewer Extensions to Serve Existing Needs Growth Neutral Focus in Sewer Extension Areas Allocation of Remaining Wastewater Treatment Capacity for Future Phases Comprehensive Long Range Plan (CLRP) & Planned Production Housing Plan (PPHP) - CLRP accepted by BOS and Planning Board in 2005 and PPHP approved by the BOS and State DHCD in 2005. Initiatives recommended for focused re-development in the existing sewer area (specifically the Village Center areas) Desire to Support Economic Development Support State Goals and Initiatives Related to Affordable Housing Integrated Planning Initiative (IPI) Identify and Quantify Alignment Gaps Related to Smart Growth and Development Initiatives and Wastewater Capacity Limitations

Article 41 Wastewater Planning Capacity Study Accomplishments to Date Released Status of Municipal Wastewater Treatment in Concord Report in December 2007 Determined that No Municipal Wastewater Treatment Capacity Existed at the Centralized Treatment Plant to Support CLRP and PPHP Recommendations Five Critical Questions Raised How much wastewater flow is associated with the desired development or re-development identified in the PPHP and CLRP? For what portion of this flow can and will the Town provide municipal wastewater management options? In what timeframe is this new, municipally handled flow anticipated to be generated? How will the Town fund design and construction costs associated with any future wastewater management solution? Which areas that are currently under-serviced have the highest value to the Town in terms of sustaining continued economic growth through redevelopment and housing?
