DRAINAGE SUMMARY
FOR
PROPOSED GARAGE
18 Dark Bay Lane
Town of Queensbury
Warren County, New York
The existing 4.7± acre site at 18 Dark Bay Lane is currently developed as a single-family
residence. The Applicant is proposing to construct a detached garage with a new driveway off of
Dark Bay Lane. The existing home and driveway will remain. An additional drainage culvert is
proposed across the new driveway to continue the conveyance of runoff down the existing ditch.
According to the Town of Queensbury regulations, all water from newly created
impervious areas shall be directed to an infiltration device sized to provide 1.5 gallons of storage
for every square foot of impervious area. Two stone diaphragms are proposed for stormwater
control, one adjacent to the driveway at the front of the site and one along the perimeter of the
new garage. Sizing calculations are as follows:
The total storage volume provided within the stone infiltration areas exceeds the required
quantities per the Town of Queensbury regulations.
