Please find below a project narrative describing proposed work including construction of a new 4-bedroom single family dwelling, a new Title V septic system, an installation of a new driveway and site work/disturbance to existing conditions at the property located at 21 Heritage Drive, South Yarmouth, MA. The proposed project falls under review and is subject to the MA Wetlands Protection Act, MGL Ch 131, Section 40 and the Town of Yarmouth Wetlands Bylaw. Existing Conditions The undeveloped property is located at 21 Heritage Drive (Map 17, Lot 13) and covers 24,157 sq. ft. of land area, which is all upland. It sits in a well-developed residential area, consisting of seasonal and year-round homes. The subject property is within an “AE” (El. 11) flood zone per current mapping. Vegetation in and around the property consist of Oak, Pitch Pine and Maple, varying from 12” to 24” diameter. There are some minor bushes as sparse ground cover. The property is located with the boundaries of NHESP estimated habitat of rare wildlife and a priority habitat of rare species. As shown on Massmapper, dated November 2025. A formal filing with MESA/NHESP for review has been made. Proposed Conditions Under this project proposal, the applicant wishes to construct a new 4-bedroom dwelling, with an attached garage. A dwelling of this size is typical for this area. The proposed septic system consists of a 1500-gallon precast septic tank, 1000-gallon precast pump chamber, distribution box and a 30’ x 20’ leaching field of pipe and stone. The proposed system requires no variances from either state or local authorities and is situated 5 ft. above the required groundwater elevation. The site was surveyed by Meyer and Sons, Inc and the topography is based on NAVD 88 datum. The new dwelling is designed to comply with the FEMA flood zone and Mass Building Department standards for buildings within a flood zone. The dwelling is to be located roughly in the center of the lot, based on topography, approximately 800 cubic yards of fill will need to be used to raise grade in order for the dwelling elevation to comply with flood zone requirements. Drywells connected to downspouts from roof draining are proposed to accept all roof runoff to prevent surface drainage impacts to the property. Exposed areas (post construction) are to be loamed and seeded with final grading as weather allows. Under this Notice of Intent, the applicant requests relief for the placement/construction of the house, garage, septic and associated utilities within an “AE” (El. 11) flood zone. Construction Sequence/Methods/Equipment The use of an excavator/skid steer will be needed to remove vegetation, manipulate grades and excavate for the proposed foundation. All site access to the property will be from the northerly side of the lot off Heritage Drive. Once excavation is complete, the footings, walls for the dwelling, then garage will be poured and backfilled. Drywells will be installed during backfill. Once construction of the building has started, regrading of the land around the dwelling and for the septic system will start. Utilities and septic system will be installed next with use of mini excavator/excavator. Finally, the driveway and final grading will be conducted with a skid-steer to restore the site to proposed conditions. Any refueling of vehicles/equipment will be conducted off site. Resource Area Impact The proposed construction activities will not have a negative effect upon any wetland values as listed in the bylaw. The alterations within a resource area (LSCSF) will involve the excavation for construction of a dwelling, utilities, septic system and driveway. Fill added within the flood zone will not have any negative impacts during a storm event. The proposed work will not have any effect on flood control. Alternatives Analysis The alternative would be to not construct the proposed dwelling and leave the property undeveloped. This is not an acceptable alternative for the property owner as the property is assessed as a buildable lot. The owner wishes to sell the property and part of the contingency is that a building can be constructed on the property.
