Town of Mashpee Conservation Commission 16 Great Neck Road North Mashpee, MA 02649 The legal opinion also addressed the distinction between new construction, new development, demolition, and reconstruction. Members discussed that demolition and reconstruction maintaining the same number of bedrooms and design flow may not constitute new construction under Title 5. The Commission also discussed revising the local regulations to clarify how redevelopment, increased living space, increased flow, and significant alterations should be defined. Members considered whether the term "significant" should be further defined by a measurable percentage or footprint threshold, noting that any numerical standard should be supported by credible studies, case law, industry standards, or comparable municipal regulations while balancing predictability for applicants with the Commission's discretion to evaluate site-specific conditions. The discussion also addressed the applicant's burden of proof. Members reviewed counsel's conclusion that a denial without prejudice may be legally supportable when an applicant fails to provide sufficient information demonstrating compliance with the Wetlands Bylaw, Regulations, performance standards, or application requirements. Members emphasized the importance of identifying missing information early in the review process to reduce repeated continuances. Members discussed cumulative effects as a property-specific evaluation rather than a single universal calculation. Factors identified included proximity to wetlands and surface waters, groundwater conditions, wellhead protection areas, nitrogen loading, the age and condition of existing septic systems, stormwater conditions, flood risk, mitigation plantings, and surrounding development. The Commission emphasized the importance of applicants providing sufficient information to evaluate cumulative effects rather than relying solely on compliance with numerical performance standards. Members also discussed how existing septic systems proposed to remain in service should be evaluated. Depending on the age, location, available documentation, and sensitivity of nearby resources, additional information such as inspection records, photographs, excavation findings, structural information, nitrogen calculations, or other documentation concerning the condition and operation of the system may be requested. The Chair summarized the discussion by emphasizing property-by-property review and the need for applicants to provide cumulative-effect information where appropriate. Members also discussed whether additional guidance or revisions to the application checklist would improve consistency by identifying information routinely expected from applicants, including proximity to water bodies, wellhead protection areas, groundwater conditions, downgradient resources, stormwater infrastructure, and existing septic systems. Staff reported that the current application checklist is generally comprehensive, although architectural plans are occasionally omitted. Staff recommended continuing to advise applicants and their representatives of the Commission's expectation that site-specific cumulative-effect information be included in project narratives or plans. It was also noted that additional questions for legal counsel could be compiled and submitted in advance of a future executive session. 5
