RE: Sheets 2.1 & 2.1, comment #1
Existing granite bounds located on the north side of Ford Crossing are identified on the plan
which are tied to and employ NAVD 1988 and Mass State Plane Coordinates (NAD 88). These have
been labeled as “Control Points” on the plans.
RE: Sheets 3.1 - 3.4,
Comment #1 – The detail has been corrected.
Comment #2 - The rip rap pad located at the outlet location has been extended to be 15' in
length terminating it at the average water elevation in the pond. Erosion control blankets are also
required until all soils have been stabilized. A row of staked silt sock at the bottom of the rip rap pad
will be shown on the CD’s.
RE: Sheet 4.1, comment #10
The two curb cuts have been modified to meet the intent in our opinion.
RE: Sheet 4.2
Comment #7 - The easement has been revised to be centered on the alignment.
Comment #9 - Roadway runoff from the intersection down the private drive drive does not
travel over paved surfaces for more than 120' before being directed overland. Runoff beyond this
point would be contained by curbing on the east side of the cohousing parking lot(s) and directed to
proposed catch basins.
Comment #10 – Corrected.
Comment #11 – Corrected.
Comment #12 - Most of the structure inverts have been modified so that the invert out is less
