Your office has requested that we limit our review to the design of stormwater management and erosion and sediment control items as it relates to compliance to local, state or relevant codes and regulations. Based upon our review of the information provided, Chazen offers the following comments for the Town's consideration: Chazen Engineenng. Land Surveying&Landscape Architecture Co., D.P.C. Chazen Environmental Services, Inc. The Chazen Companies, Inc. Town of Queensbury Michael and Tammy George December 12,2013 Page 2 Stormwater Management& Erosion and Sediment Control: 1. The proposed site improvements disturb less than 1 acre of land and will not be subject to NYSDEC Phase II Stormwater Regulations. However, this project falls within the Lake George watershed and will be subject to the requirements of Section 147-11, for Projects within the Lake George Park. The proposed site disturbs approximately 42,700 square feet and is thus classified as a major project, for which there shall be no increase in runoff volume from a ten- year-frequency/twenty-four-hour duration storm event and no increase in the rate of runoff from a twenty-five-year-frequency storm from the pre-development conditions to the post- development conditions. The Applicant has submitted a Stormwater Control Report that compares the pre-development and post-development conditions for the ten-year and twenty- five-year frequency storm events. 2. The pre-development and post-development HydroCAD model does not provide distinct inflow value depths, which indicates that the time span of 5-20 hours may not be sufficient. The Applicant shall revise the time span such that the full effects of each storm are realized. 3. The proposed post-development HydroCAD model indicates that times of concentrations less than 6-minutes were used to develop runoff quantities. The minimum allowed time of concentration is 6-minutes as per TR-55 (NYSDEC standards). The Applicant shall revise the calculations to use a minimum 6-minute time of concentration where appropriate (i.e. in subcatchments where the time of concentration is less than 6 minutes) and include the revised calculations in the SWPPP. These revisions will likely not have a significant effect on the overall runoff calculations; however, these calculations must be revised to be in conformance with the NYS Stormwater Management Design Manual. 4. The Applicant uses an arbitrary elevation of 0.00 feet for the eave trenches within the HydroCAD model. The Applicant shall revise the elevations to depict the actual elevation. 5. Section 147-11.l.3(c).4 of the town code states that stormwater recharge areas shall be located a minimum of 100 feet from the subsurface treatment system of a wastewater treatment system unless it is demonstrated that a lesser separation will not adversely affect the function of such leach fields. Pond 3P and the eastern eave trench are both located within 100 feet of the septic field. The Applicant shall either revise the design or demonstrate that the lesser separation will not adversely affect the function of the septic field. 6. The Applicant shall depict roof leaders on the site plan to ensure runoff originating from the roof is being conveyed to the eave trenches. 7. Section 6.3.1 of the NYS Stormwater Management Design Manual states, "Infiltration practices cannot be placed in locations that cause water problems to downgradient properties. Infiltration trenches and basins shall be setback 25 feet downgradient from structures..." The eave trenches and Pond 2P are located within 25 feet of structures. As such,the Applicant shall either revise the design to conform to the setback requirements or verify that the infiltration practices will not cause water problems to any structures. 8. The post-development subcatchments 3S and 4S exclude areas that are tributary to them in the post-development map. The subcatchments and model shall include all proposed grading R:\9\9130091399\91300.00-Town of Queensbury PB Engineer\91300.40-SP67-2013-George Property Homesite\Review\91300.40-Lands of Michael and Tam-,George_2G13-12 12_L1.doa Town of Queensbury Michael and Tammy George December 12,2013 Page 3 within the development since the slope and ground cover are different than the pre- development condition. 9. The existing conditions contour data does not extend far enough to the north to verify the subcatchment boundary for 2S in the post-development condition. The Applicant shall extend the existing contour data to verify the boundaries shown on the post-development subcatchment map. 10. Section 147-11.1.1(b) of the town code states that emergency overflow provisions shall be made as necessary to prevent erosion, flooding and damage to structures, roads and stormwater control measures. The Applicant models a broad-crested weir (overflow provision) in the HydroCAD model. The Applicant shall depict the weirs on the site plan sheet. 11. The Applicant shall provide a construction detail and maintenance notes for the proposed grassed retention areas, so as to confirm they are constructed as designed and maintained properly. Also, the applicant shall include a maintenance agreement which is consistent with the agreement set forth in Schedule E, Chapter 147 of the Town Code. 12. Section 147-11.1.3(c).5 of the town code states that Infiltration devices shall be designed to extend a minimum of 10% of the infiltration surface area below the prevailing frost depth or four feet (whichever is greater) in order to provide infiltration during winter months. These provisions shall be depicted on the plans. 13. The Applicant shall update the Erosion Control and Grading notes to include application rates for the seed and mulch specifications. 14. The silt fence behind SMA#1 and SMA#3 shall be extended to depict protection down gradient of all disturbed areas. Conclusions and Recommendations It is our opinion that the applicant should provide clarification for the above items and incorporate the changes in subsequent plan submissions.
