Representative: Mark Dibb <br /> <br />The property is a single-family dwelling located within the AE flood zone with a base <br />flood elevation of 11 feet. It is also situated approximately 100 to 110 feet from a coastal bank, <br />with a portion of the site within the 150-foot buffer zone. The proposed changes include adding a <br />second-story balcony on the north side of the building, a porch on the south side that will not <br />impact flood storage, and upgrading the septic system to a new I/A system located in the <br />southwestern section. The plan aims to avoid tree removal and includes precautions to protect <br />existing trees during construction. <br /> <br />COMMISSIONERS COMMENTS <br /> Clarification was sought on the proposed property changes. <br />1. The existing 3-bedroom dwelling will be expanded to a 5-bedroom home with a <br />second-story addition. Concerns include the increase in bedrooms, project <br />location, required for zoning and board of health hearings, and flood zone <br />compliance. There are also questions about the applicability of the Chapter 108 <br />flow-neutral bylaw, and a meeting with the Town Counsel may be necessary. <br /> The Assistant Agent will consult with the Board of Health and provide a response to the <br />Commission. <br /> Mr. Dibb requested a continuance for the RDA (Request for Determination of <br />Applicability). <br />PUBLIC COMMENTS <br /> <br />There were no public comments. <br /> <br />AGENT COMMENTS <br /> <br />The agent recommended an RDA (Request for Determination), citing that most of this <br />project involves a septic upgrade, which will reduce impacts to water quality. The proposed <br />project involves making minor additions to an existing single-family home within previously <br />legally altered areas. It is stated that there will be no adverse impact to the coastal bank or the <br />Land Subject to Coastal Storm Flowage (LSCSF) due to minor site grading associated with the <br />proposed septic upgrade. The existing nitrogen loading calculations are at 10.75 ppm, while the <br />proposed calculations are at 8.27 ppm. Additionally, the expansion of the existing porch will <br />replace the existing hardscape, and the construction of a second-floor balcony is expected to <br />have no disturbance to LSCSF values. <br /> <br />1. Agent recommends negative determination due to expansion of deck in <br />previously/legally altered area, reduction of hardscape, and installation of I/A septic <br />system. <br />7 <br /> <br /> <br />
