10.0 Project Alternatives <br />Avion Project SEIR <br />Page 10-4 <br />10.2 Reduced Development Footprint Alternative <br />10.2.1 Description <br />The Reduced Development Footprint Alternative would reduce the grading footprint compared to <br />the project. Through this footprint reduction the project would avoid impacts to the MHPA and <br />would not require a boundary line adjustment. Similarly, the smaller project footprint would reduce <br />impacts to sensitive vegetation communities and reduce impacts on landform alteration. Under this <br />alternative, the project would develop 117 residential units consistent with the amount anticipated <br />for the project site in the Black Mountain Ranch (Subarea I) Subarea Plan by constructing attached <br />multi-family structures with an increased density compared to the project. <br />10.2.2 Environmental Analysis of the Reduced <br />Development Footprint Alternative <br />10.2.2.1 Land Use <br />The Reduced Development Footprint Alternative would reduce the grading footprint, and thereby <br />avoid encroachment into the MHPA. Consequently, this alternative would be consistent with the <br />MHPA and would not require a boundary line adjustment. However, the increased density <br />associated with the project would require a height deviation to allow for development of 117 units <br />within the reduced grading footprint. Therefore, impacts related to land use under the Reduced <br />Development Footprint Alternative would be greater than the project. <br />10.2.2.2 Biological Resources <br />The Reduced Development Footprint Alternative would reduce the grading footprint, and thereby <br />avoid encroachment into the MHPA. Furthermore, the reduced grading footprint would also lessen <br />impacts on sensitive upland vegetation communities compared to the project. Therefore, impacts <br />related to biological resources under the Reduced Development Footprint Alternative would be less <br />than the project. <br />10.2.2.3 Cultural/Historical Resources <br />Although the Reduced Development Footprint Alternative would reduce the overall grading <br />footprint, this reduction would not occur within the general location of HJP-3. Consequently, the <br />Reduced Development Footprint Alternative would still have the potential to impact unknown <br />subsurface deposits associated with HJP-3 that could be unearthed during construction. Therefore, <br />impacts related to cultural/historical resources under the Reduced Development Footprint <br />Alternative would be similar to the project.
