Project size changes
As a result of comments on the project plan as described on 3 May 2011, HRVR made changes to the plan as described on 15 May 2013.
The changes related to project size are summarized here.
||Draft Environmental Impact Statement
3 May 2011
|Final Environmental Impact Statement
15 May 2013
|DEIS -> FEIS % change
|Residential units constructed
|Workforce housing units (rental, included in above numbers)
|Residential units for sale
|Square feet of spa and other amenities
|Number of construction 'jobs' (FTE years)
|Impermeable surface area, acres
|Excess cut / fill material, cubic yards
|Average daily water usage, gallons
|Area of disturbance, acres
|Impervious area, acres
|Development on slopes >= 25% grade, acres
- A total of 13 residential units were removed from a sensitive area of the property.
6 were deleted, as shown above, 4 were moved away from the sensitive area to a less sensitive area (FEIS buildings 47, 48, 50, and 52), increasing the housing density in that area, and
3 were combined into unspecified existing structures, i.e. changed from single-family to duplex units (for workforce housing).
- The DEIS amenities included a 4,000 square foot grass-slope amphitheater.
If this were removed from the calculations, the DEIS number would be 43,435 square feet and the DEIS -> FEIS change would be -8.7%.
- Although HRVR consistently equates an FTE-year to a job, the two are not equivalent.
Further discussion appears on the Construction employment page.
The FEIS claims a reduction in development on steep slopes of 60%, apparently obtained as follows:
- The DEIS p. 193, Table III.A.12 shows 114.1 acres of steep slopes after grading ('Proposed Conditions'), within a total Development Area of 314.02 acres, resulting in 36.3% of the Development Area being on steep slopes.
- The FEIS p. 103, Table IV.E.1 does not show acreage, but states that 14.5% of the Development Area constitutes steep slopes.
In this case, however, it appears that the base for the calculation is not the 314.02 acre Development Area, but something called the 'development footprint', which is stated to be 66.13 acres.
- HRVR computes the decrease by comparing the two percentages and 14.5 is, indeed, 60% less than 36.3, but since the two values are percentages of different total acreages such a comparison is invalid.
Rather than using percentages as input, the table above shows a comparison using actual acreage, calculated as follows:
- DEIS steep-slope acreage is obtained from charts on p. 194-195, which show 12.46 acres east of Binnewater Road and 2.03 acres west of the road, for a total of 14.49 acres.
- FEIS Appendix K.9 similarly shows a total of 9.53 steep acres (as 415,194.36 square feet) on both sides of the road, although the slopes in that figure represent Existing Conditions, i.e. before grading.
As a cross-check, calculating the acreage from HRVR's statement that 14.5% of the 66.13 development footprint is steep slope gives a slightly larger result of 9.59 acres.
We'll use that number.
- The actual reduction in development on steep slopes is therefore (14.49 - 9.59) / 14.49 = 33.8%, about half what HRVR claims.
