Dear Mr. Brown:
The Environmental Design Partnership, LLP (EDP) is providing you this letter in response to review
comments provided by the LaBella dated August 18, 2022. On behalf of the applicant Jeff and Nancy
Randles, we offer the following response to comments and additional information:
According to the site plan review application, the proposed site improvements will disturb less than one
(1) acre and thus the project is not required to obtain coverage under the NYSDEC SPDES General
Permit for Stormwater Discharges from Construction Activity (GP-0-20-001). However, this project falls
within the Lake George watershed and therefore is subject to the stormwater management
requirements set forth in Section 147-11 of the Town Code for projects within the Lake George Park.
Comments related to the stormwater management and erosion and sediment control features proposed
for the site are offered below. -
Response: Comment noted.
2. According to the site plans, this project proposes land disturbance of 10,000 (+/-) square feet and is
classified as a minor project for stormwater management by Town Code Section 147-11.E(1)(a). With
the minor project classification, the Applicant has opted to use the alternative stormwater calculation
method described in Town code section 147-11.1(2)(a), which allows a flat rate of 1.5 gallons of
stormwater to be used for every square foot net increase in impervious area, where net increase is
the difference between predevelopment and post development conditions.
Response: Comment noted.
3. Town code section 147-111(2)(c) states infiltration devices shall not be installed up gradient within 20
feet of the subsurface treatment system of a wastewater treatment system. It is difficult to discern
where the project site and neighboring absorption fields are located (as applicable). The Applicant to
revise or clarify accordingly to support a review of 147-111(2)(c).
Response: Neighboring systems have been added to Sheet 3 of the Site Plans. There are no
wastewater treatment systems within 20 feet of any infiltration devices.
4. The callout for stormwater management practice SMA #4 states that it will have a bottom elevation of
332.5 throughout the section. The proposed contours do not match the callout, as the portion of the
practice closest to the lake shows an elevation of 332 feet. The Applicant to clarify, and revise the site
plans if applicable.
Response: SMA#4 has been updated for the bottom of the drip edge to be 331.5 throughout the
section.

5. Town code section 147-111(2)(a) states that the location of the infiltration devices shall be determined
based upon soil test results. Town code section 147-111(2)(e) prescribes the vertical separation
distances for infiltration practices. It does not appear that deep soil test pits nor infiltration tests were
performed in support of the design. The Applicant to perform the tests and provide the results.
Response: Test pits and infiltration tests have been performed and depict fine loamy sand to
depths of 48". Infiltration rates stabilized between 80-96 inches per hour. Refer to Sheet 2 of
the Site Plans for results and locations.
6. As applicable, the Applicant to add downspout locations to the site plans.
Response: Downspout locations have been added to the site plans as applicable, refer to
Sheet 4 of Site Plans for location.
7. Sheet 6 of the site plans has a callout stating the limit of work is 29,000 SF and a limit of disturbance
of 11,250 SF. The Applicant to clarify what construction activities will take place within each described
boundary.
Response: The limit of disturbance is 11,250 SF and by definition, the area of stormwater
management devices and sanitary sewer is not included in the area of disturbance calculation.
There will be a total of 29,050 SF of work, which includes portions of grading that would not
need to take place if stormwater devices were not needed. The 11,250 SF of disturbance
includes the necessary grading for the driveway and proposed addition.
8. It does not appear that the grading plans depict the overflow weir elevation for SMA #3 and the
Applicant to revise accordingly.
Response: Sheet 4 of the Site Plans have been updated to include the overflow weir elevation
for SMA#3.
9. The Applicant to clarify the method of pre-treatment prior to entry to the infiltration practice.
Response: Pre-treatment for infiltration devices taking driveway runoff includes the grass
swale that diverts runoff to the corresponding stormwater management area. Areas taking
only roof runoff do not need pre-treatment.
10. It appears the erosion and sediment control plan is incorporated into the overall site plan. It does not
appear that the ESC plan is complete as no temporary ESC controls are depicted to protect the
infiltration areas. Section 6.3.6 of the NYS SMDM states "Infiltration practices shall never serve as a
sediment control device during site construction phase. In addition, the Erosion and Sediment Control
plan for the site shall clearly indicate how sediment will be prevented from entering an infiltration
facility." The Applicant shall revise the plans to clearly indicate how sediment will be prevented from
entering the infiltration facilities during the site construction phase.
Response: Refer to Sheet 6 of the Site Plans, two sediment traps have been added to prevent
sediment from entering in the two depression areas.
11. Further, it does not appear that a temporary soil stockpile and temporary ESC controls for a
temporary soil stockpile are depicted on the site plans. The applicant to clarify if there will be a
temporary soil stockpile and revise the plans if applicable.
