The adjustment would increase Davis'0.22 acre lot to 0.81 acres,providing for greater side setbacks to construct a single family residence on the lot as well as a shared curb cut in an effort to minimize the impact on traffic on State Route 9L.The proposed lot would also have a 60 foot non-disturbance covenant from the eastern property line as agreed to by Davis and his neighbor to the east, Charles C. Freihofer, III (see exhibit marked "S2" attached to the application). Davis'existing parcel provides for unique buildable lot which would only benefit from the proposed variance by reducing the impact on not only the neighborhood but also Mr.Freihofer's privacy given the narrow dimension and size of the lot (SBL 239.18-1-27.2) as it currently exists (see exhibit marked "S1" attached to the application). The proposed boundary line adjustment would have the same environmental impact as the existing lot but would allow the parcel to conform to the majority of the lots in the neighborhood, thus adding to the essential character and appearance of the neighborhood. As such,the area variance requested within this application would not only prevent Queensbury Planning Board and Zoning Board of Appeals 480248.1 March 15, 2017 Page 2 an undesirable change to the character of the neighborhood but it would actually add to said character by allowing a lot that substantially conforms to the size and dimensions of the majority of the surrounding parcels. Relief is requested for the two parcels having non-conforming lot areas, where 2-acres is required per Chapter 179-3-040 (5) of the zoning code, where 2-acres of minimum lot size is required. In addition,relief is requested from Chapter 147-111(3) (c) [4] where 100-ft of horizontal separation is required between a stormwater recharge area and a subsurface wastewater treatment system. As the stormwater management devices are downgradient from the wastewater absorption field and an enhanced treatment wastewater system is proposed,the SMPs will not have an adverse impact upon the wastewater system.

Also associated with the project is the construction of a small drive/parking area, which will branch off the existing drive that accesses the westerly adjoining parcel. The project also involves the construction of a new enhanced treatment wastewater system, landscaping and stormwater management practices. Project disturbance totals 13,000± square-feet. Existing Site Conditions Presently, the project site is vacant, aside from a small portion of the existing drive which accesses the westerly neighboring parcel. The wooded portions of the site consist of a mixture of evergreen and deciduous trees and brush. The proposed house site is lightly wooded with medium sized evergreen trees. The project site slopes east to the north at 10-20%; site soils are mapped as bice very bouldery fine loamy sand, HSG-B. Soil test pits in the area of the proposed wastewater system revealed fine sandy loam and silty fine sand with a boundary condition at 48-inches and a percolation rate of 4 minutes per inch. Desmon Storm Events: 10-year, 24hr, Type-ll distribution, 3.6" 25-year, 24hr, Type-II distribution, 4.5" Existing Conditions Calculated Stormwater Runoff from the Site: Design Point 1 - Runoff to Lake 10 -year design storm (3.6") 0.45 cfs 0.027 acre-feet 25 - year design storm (4.5") 0.90 cfs 0.047 acre-feet Proposed Stormwater Management The Town of Queensbury requires that there will be no increase in runoff volume from a 10-year design storm and no increase in runoff rate from a 25-year design storm in predeveloped vs. developed site conditions. Runoff from the roof areas will be captured in roof gutters and piped to two rain gardens, while runoff from the new driveway will be captured in a catch basin and conveyed to a subsurface infiltration bed. An infiltration rate of 5-inches per hour is taken in the rain gardens and the subsurface infiltration facility. Runoff calculations have been prepared utilizing SCS TR-20 methodology and HydroCAD analysis software for 10-year and 25-year Type-ll simulated rainfall distributions. Criteria utilized in the analysis are summarized as follows: Design Storm Events: 10-year, 24hr, Type-II distribution, 3.6" 25-year, 24hr, Type-II distribution, 4.5" Proposed Conditions Calculated Stormwater Runoff from the Site: Design Point 1 - Runoff to Lake 10 - year design storm (3.6") 0.38 cfs 0.021 acre-feet 25 - year design storm (4.5") 0.74 cfs 0.038 acre-feet The developed site has been modeled as a series of subcatchments (drainage areas) and ponds, as shown on the HydroCAD drainage diagram. Full results of stormwater runoff computations are attached to this report. Results The analyses show that the system of rain gardens and subsurface facilities are of adequate capacity to manage calculated runoff from the proposed house and drive for the design storms. Reductions in both runoff rate and volume are realized from the existing conditions for the 10- and 25-year design storms. Construction Phase Erosion Practices Practices to be implemented during construction for erosion and sediment control include silt fencing and temporary sediment traps in various portions of the total disturbed area. Silt fencing will be placed across slopes (on the contour) in all areas downgrade of disturbed areas. Temporary sediment traps will be utilized in areas where construction phase runoff concentrates. Temporary Erosion and Sediment Control Measures Erosion and sediment control measures will be incorporated into the construction of the project. These practices will comply with the New York State Department of Environmental Conservation publication entitled "New York Guidelines for Urban and Sediment Control' (the blue book). The following temporary erosion and sediment control devices are to be utilized: Sediment Control Fence Silt Fence shall be used to control erosion from sheet flow on slopes not to exceed 1 on 3. Concentrated flows shall not be directed toward the silt fence. The silt fence must be installed parallel to the contour lines to eliminate drainage along the fence. Temporary Seeding Land that is stripped of vegetation will be seeded and planted as soon as possible. Any area that will remain cleared but not under construction for 5 days or longer will be seeded with a ryegrass mixture and mulched to stabilize soil until construction resumes. Temporary Diversion Swales Temporary diversion swales shall be constructed either to divert clean stormwater runoff from newly graded areas or to direct sediment laden runoff to a sediment trapping device. Dust Control Measures for dust control during construction shall be implemented as needed. Daily water sprays will be used during dry conditions. In addition to water sprays, temporary mulching, temporary seeding and covering stockpiles with tarps shall be implemented when necessary. Erosion Control Blanket Fabricated straw or biodegradable mesh blankets shall be utilized to protect and temporarily stabilize slopes of 1:3 or greater and applied to graded, topsoiled and seeded slopes. Blankets will be attached with staples or stakes in accordance with manufacturer's recommendations. Blankets will be maintained in place until permanent groundcover is firmly established. Control of Litter, Construction_Debris-and Construction Chemicals During the course of construction, the site shall be kept clear of debris and litter which could be transported by water or wind. This material shall be picked up daily and shall be stored in waste debris containers where it will be securely held. All petroleum products or other waste contaminants which are water soluble, or could be dispersed and transported by stormwater, shall be stored in covered containers and be regularly removed from the site and properly and legally disposed of. All petroleum or other hazardous materials shall be stored and handled in conformance with NYSDEC spill prevention and containment requirements. Senuence of Construction Prior to the start of construction, the contractor shall install the sediment control fence along the low side of each area to be disturbed to contain runoff from the construction site. Following the completion of all planting and the establishment of all grass areas, any collected sediment, hay bale dams and sediment control fencing shall be removed. Any debris from the perimeter of the site shall be removed and all waste material shall be disposed of in a legal manner. Maintenance of Temporary Erosion & Sediment Control Devices The contractor shall inspect the sediment control fence weekly and after every rain event and remove trapped sediment and maintain the devices such that they are in good working order. Permanent Erosion Control All pervious areas shall be graded, topsoil installed and seeded or planted as soon as practical. Seed beds shall be mulched with straw and plant beds shall be mulched with pine bark mulch. Seeded areas on slopes over 1:3 shall be stabilized with erosion control netting as specified on the plans.
