• The Original Project would have 98 lots. Alternative 4 would have 51 lots. The average lot size would nearly double, from 0.60 acres per lot under the Original Project to 1.13 acres under Alternative 4. • With 51 units, Alternative 4 would not require one court and would substantially shorten the main access street. • The fill of ephemeral streams is estimated to be reduced from 2,708 lineal feet for the Original Project, to 145 feet for Alternative 4. Disturbance of seeps would also be reduced, from approximately 2,000 square feet for the Original Project to less than 1,200 square feet for Alternative 4. • The proposed 6.5-acre neighborhood park would not be included in Alternative 4. The staging area will remain and regional and local trails would be provided in the publicly owned open space area. • In case of fire or other emergency, the Project will have three, rather than two accesses. One access point will be Hearst Drive, another will be a fire road and the third will be from the north, via the Grey Eagle Estates subdivision. The fire access road would connect from the City's existing water tank on the southwest section of the site to the end of the cul-de-sac by Lot 51. The other would connect to the existing City public access easement within Grey Eagle Estates and then would head to the north towards Grey Eagle Court. It would be configured as an entrance-only route for public safety vehicles from Grey Eagle to Oak Grove. • One of four detention basins required in the Original Project would not be required in Alternative 4. • The elimination of some development areas and roadways results in a smaller development footprint for this alternative. • Alternative 4 would use two onsite balance fill areas for deposit of excess soils generated from grading the roads and lots. Finding: Feasible The DEIR identified several differences in the environmental effects of Alternative 4 as compared with the Original Project: • Aesthetics -With larger lots, Alternative 4 could allow larger homes and thus may have a greater visual impact. As conditioned, the building floor area for these lots would be limited to 20 percent of the lot area and large building setbacks would be established between the structures on adjoining lots. These factors with the design guidelines controlling building architecture, the potential visual impacts of these homes would be reduced. • Air Quality -Alternative 4 would have slightly greater impact than the Original Project on dust generation during construction of the individual lots, due to a Page 7 of 43
