Project disturbance for total project build -out totals 1.55-acres. The project site is located in the northeast corner of the Barringer Heights subdivision on the east side of Richmond Hill Drive, in the Town of Queensbury, Warren County, New York. 2.0 EXISTING SITE CONDITIONS Presently, the project site is a vacant lot that is separated by the existing subdivision road. The portion of the parcel top the west will remain undeveloped as per the original subdivision approval. The existing site drainage pattern is generally easterly towards the National Grid power lines. Site soils over the majority of the site are mapped as Elnora loamy fine sand, HSG-A. A copy of the USDA soils map is included in the appendix of this report. Site slopes over the majority of the site range from 1-3%. Existing Conditions Summary Total Project Site Area: 29.03 Acres Buildings Coverage: 0 SF Driveways: 0 SF Total Impervious: 0 SF Design Storm Events 25-year 24-hr Type -II distribution 4AN Existing Conditions Calculated Stormwater Runoff from the Site — 25-year design storm (4.4") 0.0 CFS 0.0 acre-feet 3.0 PROPOSED DEVELOPMENT Proposed Conditions Summary Total Project Site Area: 29.03 Acres Buildings Coverage: 5,130 SF Driveways: 2,617 SF Total Impervious: 7,747 SF Project Disturbance: 1.55 Acres 4.0 PROSPOSED STORMWATER MANAGEMENT The proposed stormwater management will store and treat all stormwater runoff from impermeable surfaces on each individual lot. The runoff from the proposed residential homes will be directed to an eave trench at the perimeter of the structure and will be infiltrated into the well -drained soils. The runoff from the new driveways will be pitched to a stone infiltration trench along side the driveways and infiltrate into the well -drained soils. All runoff from impervious surfaces will be captured and treated on each individual lot. 5.0 NYSDEC REQUIREMENTS The proposed development is a residential subdivision that will disturb more than 1 acre but less than 5 acres and will be for less than 5 new lots. Based on the proposed development NYS DEC only requires a NOI to be filed with an Erosion & Sediment Control Plan. 6.0 TOWN OF QUEENSBURY REQUIREMENTS The Town of Queensbury requires that for residential projects, the peak developed discharge rate and volume from the 25-year, 24-hour storm not exceed the predevelopment rate and volume. Existing 25-year peak storm volume: 0.0 AF Developed 25-year peak storm volume: 0.0 AF Existing 25-year peak storm discharge: 0.0 CFS Developed 25-year peak storm discharge: 0.0 CFS The 25-year storm calculations show that the Town's requirements are met. 7.0 ENDANGERED SPECIES In accordance with Part I.F.4 of GP-015-0-002, discharges from construction activities that adversely affect a listed or proposed to be listed endangered or threatened species are ineligible for coverage under the general permit. An inquiry was made to NYSDEC during the initial subdivision development which included this portion of the parcel. No endangered or threatened species were located within the proposed area to be developed. We have continued the no cut buffer along the east side along the power lines as requested by the planning board in the previous approval. 8.0 ARCHAEOLOGICAL RESOURCES & HISTORIC PLACES In accordance with Part I.F.8 of GP-015-0-002, discharges from construction activities that have the potential to affect historic property are ineligible for coverage under the general permit. An inquiry was made to NYSOPRHP during the initial subdivision; which included this area to be developed, and no historic property was identified within the original subdivision boundaries. 9.0 CONSTRUCTION PHASE EROSION PRACTICES Practices to be implemented during construction for erosion and sediment control include silt fencing and temporary sediment basins 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. 10.0 TEMPORARY EROSION & 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). Separate erosion and sediment controls will be installed for each phase of construction. 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. 2. Temporary Seedina 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 five days or longer will be seeded with a ryegrass mixture and mulched to stabilize soil until construction resumes. 3. 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. 4. 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. 5. Erosion Control Blanket Fabricated straw or biodegradable mesh blankets shall be utilized to protect and temporarily stabilize slopes of 1:3 or greater and shall be applied to graded, topsoiled, and seeded slopes. Blankets will be attached with staples or stakes in accordance with manufacturer's recommendations. Blankets on cut slopes and vegetated ditchlines will be maintained in place permanently and allowed to biodegrade. 11.0 CONTROL OF LITTER, CONSTRUCTION DEBRIS & 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 shall 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. 12.0 SEQUENCE OF CONSTRUCTION The project is to be undertaken in one phase, being the construction of the individual houses and the respective lot development. Prior to the start of construction, the contractor shall install the sediment control fence along the low side of each area to be disturbed in order to contain runoff from the construction site. Concurrently, the stabilized construction entrance is to be installed in the location of the proposed driveway. Topsoil is to be stripped and stockpiled for reuse over the regraded areas. Temporary vegetation is to be installed over the regraded areas which will not become driveway areas. Following the respective house construction, the final surrounding grades are to be established, driveway installed, soil restoration is to be performed, place topsoil eave trenches, stone infiltration trenches and final vegetation installed. Following the completion of all planting and the establishment of all grass areas, any collected sediment and sediment control fencing shall be removed. Any debris from the perimeter of the site shall be removed and dispose of all waste material shall be disposed of in a legal manner. 13.0 MAINTENANCE OF TEMPORARY EROSION & SEDIMENT CONTROL DEVICES The sediment basins shall be inspected at least weekly and after every rain event by the contractor. When 50% of the volume of the trap is full, the contractor shall remove collected sediment and dispose of properly. 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. 14.0 OPERATION & MAINTENANCE PLAN Each respective lot owner is to provide the maintenance needed in order to ensure continuous and effective operation of the stormwater control practices on the respective lots. Maintenance includes vegetation trimming and sediment removal in the stone infiltration trench and eave trenches. Mowing and trimming should be performed as needed throughout the spring, summer and fall, typically weekly or semi -weekly. Sediment removal and inspection of the stone infiltration trench should be performed annually or as needed due to surrounding and contributing site conditions. If long-term infiltration capacity becomes reduced, the stone trench should be excavated, and new stone & filter fabric installed 15.0 PERMANENT EROSION CONTROL All pervious areas shall be graded, topsoil installed and seeded or planted as soon as practical, but in no case shall finish graded soils be exposed for more than five days. 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 blankets as specified on the plans. 16.0 INSPECTION REQUIREMENTS In accordance with Part IV of GP-0-15-002, the owner or operator of each construction activity shall have a trained contractor inspect the erosion and sediment control practices within the active work area on a daily basis to ensure that proper maintenance and functionality is realized for the practices. If soil disturbances upon the site have been temporarily suspended and proper stabilization methods have been implemented, the trained contractor may suspend inspections until site work is restarted.
