Area post development based on aerial estimates includes a portion of delineation <br />wetland and is subject to change. <br />6 Hayfields (101.37 ac.) and cropland (61.19 ac.) are based on aerial estimates and include portions of the delineation <br />wetland. <br />7 Impervious surface pre-development based on farmstead aerial estimate and assumed to be ~50% impervious. Impervious <br />surface post-development based on several assumptions and the current concept plan (see Table 5). <br />8 Pre-development open space based on an aerial estimate and post-development open space based on the current site plan <br />and included portions of the wetland and wooded areas. <br />9 Lawns/landscaping pre-development included 3.04 ac. for the farmstead and post-development based on the remaining area. <br />10 Pre-development land cover (247.65 ac.) = 2.18 + 60.89 + 162.56 + 3.04 + 14.65 + 3.04+ 1.29 (wetland not already <br />accounted for). <br />11 Post-development land cover (247.65 ac.) = 2.18 + 26.96 + 42.58 + 101.44 + 63.64 + 7.55 + 3.30 (wetland not already <br />accounted for). <br /> <br />Construction Emissions – Scope 1 <br />GHG emitted during the construction phase is primarily from mobile equipment (passenger cars, <br />trucks, and construction equipment). It was assumed the construction would last for <br />approximately 150 working days (30, 5-day weeks). Vehicles were estimated to travel fifty miles <br />per day. It was assumed daily travel over fifty miles would require overnight accommodation; <br />thus, fifty miles per day for all vehicles was used as a high-end estimate. The number of vehicles <br />onsite during the construction phase will likely vary throughout the construction season, the <br />number of vehicles on site per day was an estimate. Given the multiple assumptions made in this <br />calculation, it is best to view the reported value as an order-of-magnitude estimate. Emissions <br />were multiplied by the expected construction period of nine years and divided by the project <br />timeline (50 years) to get annualized emissions.
