1 C. Topography and Slopes 1. Existing Conditions a. Site Topography and Relationship to Surrounding Topography The Site is gently rolling, as is the surrounding topography (Figure I.A-8). The Property is generally higher along its frontage on Pines Bridge Road, with elevations of 628 feet at its southwest corner, with the Property sloping in a generally easterly direction down to a low point of 580 feet at the location of the on-site wetlands. b. Special Topographic Features There are no special topographic features on the Property. c. Slope Analysis Chapter 108 of the Code of the Town of New Castle, entitled Steep Slope Protection, regulates development of steep slopes to preserve, protect and conserve steep slopes, and properly manage and control disturbance of steep slopes. Chapter 108 defines "steep slopes" as follows: Any geographic area proposed for disturbance, whether on a single lot or not, having a topographical gradient of 15% or greater (ratio of vertical distance or horizontal distance), with a minimum horizontal dimension of 10 feet, and a minimum area as defined below, whether man-made or natural, and whether created by a retaining structure or not. Steep slopes are further categorized as: 129

2 i. MODERATELY STEEP SLOPE- A slope equal to or greater than 15% but less than 25% and covering a minimum horizontal area of 3/10 of an acre or 13,068 square feet. ii. VERY STEEP SLOPE-A slope equal to or greater than 25% but less than 35% and covering a minimum horizontal area of 2/10 of an acre or 8,712 square feet. iii. EXTREMELY STEEP SLOPE-A slope equal to or greater than 35% and covering a minimum horizontal area of 1/10 of an acre or 4,356 square feet. The approval authority and the review procedure for a Steep Slope Permit varies, depending on the category of steep slopes (as defined above) to be disturbed. If the areas of the proposed disturbance within each of the three categories of steep slope are individually less than the minimum areas defined above, then the area of all contiguous steeply sloped areas proposed for disturbance are to be merged as specified below. A steep slope area is to be regulated under Chapter 108 of the Code of the Town of New Castle Code if the total of all the steeply sloped areas proposed for disturbance, as adjusted according to the weighting factors identified below, exceeds a sum of 3/10 of an acre or 13,068 square feet. Moderately steep slope area X Very steep slope area X Extremely steep slope area X 3.0 = Total weighted area If no category of steep slope meets or exceeds the minimum area requirement for a steep slope, but the total weighted area of two or more slope categories exceeds 13,068 square feet (3/10 acre), then the single slope category that has the largest area after the application of the relevant weighting factor determines approving authority and review procedures for the disturbance of steep slopes. However, where there is a Wetland Permit application pending before the Planning Board, such as is the case for this Project, the Planning Board 130

3 would be the approval authority for any Steep Slope Permit, if a Steep Slope Permit was required. A Steep Slope Permit is required in the case of the subject application because new steep slopes are being created, which require a Steep Slope Permit under Section 108-3A of the Town Code as discussed in Section III.C.2.d. Figure III.C-1 provides a slope analysis of the existing Property. The majority of the Property (92%) has a gradient of less than 15%, falling below the criteria for slope regulation as defined in Chapter 108 "Steep Slope Protection" of the Town Code. 6% of the Site contains slopes ranging from 15% to less than 25%. These slopes primarily exist along the southwesterly portion of the Property. Approximately 1% of the Property contains slopes of 25% up to 35% and less than 1% of the Property contains slopes equal to or greater than 35%. The area of "moderately steep slopes" is situated adjacent to the existing residential structure on the Property, and within an area at the front of the Property between the abandoned tennis court and Pines Bridge Road. Areas of steeper slopes occur near the stone wall marking the property boundary at the southwest portion of the Site. 2. Potential Impacts a. Proposed Grading Areas of proposed grading showing 2-foot contour intervals are depicted on Figure III.C-2, and proposed clearing and grading limit lines are depicted on Figure I.A-9. Approximately 3.6 acres of the 8.33 acre property are proposed to be disturbed (graded). The Site is currently developed, and the area of proposed grading encompasses areas of prior disturbance. The proposed grading is designed to direct stormwater towards the drain inlets in the proposed asphalt parking lot and driveway, and thence to the proposed subsurface stormwater detention system, and to minimize to the extent practicable grading impacts within the wetland buffer. The proposed grading within the pervious pavement area is designed to direct stormwater towards the swale located to the west of the parking areas. 131

4 The grading will provide a finished floor elevation of approximately for the main floor of the building, and for the lower level. The existing grade at the front of the building is approximately 597, and at the rear is 590. The siting of the building in this manner allows the building to work with the existing topography while accommodating the proposed uses. For example, siting the building at the existing rear elevation of 590 limits disturbance of the existing wetland buffer, and limits the amount of cut require to create the necessary space for the religious education classrooms. It also allows for the creation of a walk out lower level meeting the needs of students using the religious education classrooms for accessibility. The elevation of Pines Bridge Road at the location of the driveway is approximately , so it is necessary to provide an uphill gradient from the 601 elevation at the front of the building up to the roadway at elevation This increase in grade is provided by raising the existing grade at this portion of the Property to meet the roadway grade to provide a smooth transition for the driveway and the controlled flow of stormwater. The building has been raised to the 601 elevation to provide for less cut for the lower classroom level and a less steep transition to the roadway elevation in front. In addition, the grading plan provides for a flatter area at the front of the building to provide for handicap accessibility and a more level pick-up and drop-off area. The proposed rear parking lot elevation ranges from 586 at its point closest to the proposed building, to a low elevation of approximately 582 to provide for a continued smooth transition to the front pick-up and drop-off area and the driveway to the road. The existing grade ranges from approximately 585 to 579. The parking lot has been designed to match the existing grade as closely as possible while providing for the controlled flow of stormwater and a smoothly transitioning surface for vehicular and pedestrian traffic. No grading is proposed within the local wetlands. However, because of Site limitations, most of the proposed grading and fill would occur within the Town-regulated 150-foot wetland buffer area. 132

5 The building has been designed to meet the long term objectives of the UWMS which includes religious educational classrooms on the lower level as discussed above. The building will serve as a retaining wall to minimize impacts associated with grading of the subject Property to accommodate the existing elevation grade change from approximately 597 at the front to approximately 590 at the rear. In general, the proposed siting of the building takes the best advantage of the topography to minimize grading and environmental impacts. b. Amount and Location of Earthwork Anticipated (Preliminary Cut and Fill Analysis), Total Amount of Disturbance, And Effect Of Such Earthwork The anticipated area of disturbance is approximately 3.6 acres of the 8.33 acre Property. The anticipated earthwork volumes are summarized in the table below. Earthwork Analysis Volumes Cut 4,000 cubic yards Fill 9,200 cubic yards Net 5,200 cubic yards borrow Figure III.C-3 depicts the locations of the areas of estimated cut and fill, and respective approximate depths of cut and fill required throughout the area of disturbance as a result of the proposed development. The largest areas of anticipated cut on the Property are located in the vicinity of the proposed building, within the swale to the west of the parking area, and the proposed overflow parking at the southeastern portion of the Property. The proposed grading is discussed above in Section III.C.2.a. A retaining wall with a height ranging from approximately 1.2 feet to 7.5 feet will be required along the northeastern property line adjacent to the Con Ed property to permit the construction of the rear parking area while minimizing the extent of grading. The Con Edison property slopes down from the UWMS Property. With the design of the rear parking lot as discussed above in Section III.C.2.a, a retaining wall is necessary to provide for the controlled flow of stormwater and a smoothly transitioning surface for vehicular and 133

6 pedestrian traffic. The retaining wall provides mitigation for additional grading and land disturbance that would otherwise be necessary as discussed in Section I.D.3. Mitigation for all proposed earthwork during construction is discussed in detail in Sections III.C.3.a and III.N.2.b, including erosion and sediment controls for the Project which will be designed to meet or exceed the criteria of the New York State Department of Environmental Conservation SPDES General Permit No. GP for Stormwater Discharges from Construction Activities. An Erosion and Sediment Control Management Program will be established for the proposed development, beginning at the start of construction and continuing throughout its course, as outlined in the "New York State Standards and Specifications for Erosion and Sediment Control," dated August The anticipated development on the Property is expected to require approximately 5,200 cubic yards of borrow. The source of the material will depend on what other construction projects are in operation within the area at the time. Whichever project that has suitable excess material at the closest distance to the Project at a suitable price will be utilized. For the location of the proposed subsurface sanitary sewage treatment system, the Westchester County Department of Health requires run-of-bank sand and gravel fill material obtained through a supply company. c. Impacts To Topography, And Effect Of Such Impacts Impacts to the existing slopes on the Property are depicted on Figure I.A-9. As stated above, the majority of the Property (92%) has a gradient of less than 15%, falling below the criteria for slope regulation as defined in Chapter 108, constituting a moderately flat topography. 6% of the Site contains slopes ranging from 15% to less than 25%. These slopes primarily exist along the southwesterly portion of the Property. Approximately 1% of the Property contains slopes of 25% up to 35% and less than 1% of the Property contains slopes equal to or greater than 35%. The area of "moderately steep slopes" is situated adjacent to the existing residential structure on the Property, and within an area at the front of the Property between the 134

7 abandoned tennis court and Pines Bridge Road. Areas of steeper slopes occur near the stone wall marking the property boundary at the southwest portion of the Site. The Proposed Project impacts approximately 7,837 square feet (0.18 acres) of slopes 15% and greater on the 8.33 acre Property (Figure I.A-9). As such, it is the Applicant s opinion that impacts to the Site topography will be minimal, and that the Project, as designed, will not have a significant impact on drainage patterns and flow to the wetlands. As discussed below in Section III.F.2.a.ii, on-site stormwater runoff will be directed to the proposed stormwater management systems, including infiltration measures. The proposed drainage patterns will remain generally consistent with the existing drainage patterns on the Property, and the discharge points will remain the same. As discussed in greater detail within Section III.F.1.a.iv and Section III.F.2.a.ii, existing drainage area EDA-1 is approximately 5.19 acres in size and encompasses the two larger wetlands located adjacent to the southern property line. Proposed drainage area PDA-1 is approximately 4.71 acres in size and also includes the two larger wetlands located adjacent to southern property line. Therefore, the drainage area that encompasses the wetlands is not anticipated to change significantly with the proposed grading, created slopes, and retaining walls, in the Applicant's opinion, nor will the proposed site design significantly impact the wetlands in the opinion of the Applicant. As the wetlands on the property are primarily fed by groundwater, the Applicant does not anticipate that alteration of the site topography from the proposed earthwork and grading would have any impact on the overall hydrology of the wetlands. The overland flow that does contribute to the wetlands under existing conditions may be redirected by site grading, but the stormwater collection and treatment measures have been designed to return these surface flows to the wetlands after treatment. 135

8 d. Acreage Impacted By Construction For Each Of The Town's Regulated Steep Slope Categories, Including Quantification Of Existing Steep Slopes To Be Disturbed and New Steep Slopes To Be Created And The Effect Of Such Impacts All slopes within the approximately 3.6 acres of the Site proposed to be disturbed have been grouped together according to the formula set forth in Chapter 108 of the Town Code and as described above in Section III.C.1.iii. The weighted area of steep slope disturbance calculated in this manner equals approximately 10,488 square feet (Figure I.A-9), therefore falling below the 13,068 square foot minimum necessary for a Steep Slope Permit in connection with the disturbance of elimination of steep slopes. A Steep Slope Permit is still required for the creation of steep slopes. Limited areas of steep slopes will be created as a result of the Project, ranging from 20% to 33%. In addition, a retaining wall along the northeastern property line adjacent to the Con Edison property would reach heights of 1.2 to 7.5 feet, as discussed above in Section III.C.2.b. The retaining wall provides mitigation for additional grading and land disturbance that would otherwise be necessary as discussed in Section I.D.3. In other words, without a retaining wall, a greater land disturbance would be required. The retaining wall helps to limit land disturbance by enabling the proposed grading (the height of the proposed land surface) to meet the existing grading (the height of the existing land surface) over a shorter horizontal distance, which is the width of the retaining wall. Mitigation for all proposed earthwork during construction is discussed in detail in Sections III.C.3.a and III.N.2.b, including erosion and sediment controls for the Project which will be designed to meet or exceed the criteria of the New York State Department of Environmental Conservation SPDES General Permit No. GP for Stormwater Discharges from Construction Activities. An Erosion and Sediment Control Management Program will be established for the proposed development, beginning at the start of construction and continuing throughout its course, as outlined in the "New York State Standards and Specifications for Erosion and Sediment Control," dated August These measures will also help protect the wetlands. 136

9 The quantity of new steep slopes to be created by construction of the Project, using the definition of "steep slopes" provided by Chapter 108 of the Town Code discussed above in Section III.C.1.c, is zero. However, there is no minimum area requirement for obtaining a steep slope permit for newly created steep slopes under Section A of the Town Code. The following quantities of steep slopes are created in connection with the Proposed Action as illustrated in Figure I.A-10: Moderately steep slope (15% to less than 25%): 4,901 square feet Very steep slope (25% to less than 35%): 2,814 square feet Extremely steep slope (35% and Greater): 594 square feet No disturbance is proposed within the area of the prehistoric site. Thus there are no potential impacts for this area of the Property. The greater exposed portion of the wall faces the Con Edison property. In the Applicant's opinion, the visual impact of the retaining wall on the Con Edison Property is minimal. The proposed retaining wall facing the Con Edison Property ranges in height from 1.2 to 7.5 feet. The Con Edison property does not, and will not contain residences because the property contains overhead electric transmission lines. The width of the Con Edison Property is approximately 280 feet, with the overhead lines located approximately in the middle of the property. The side of the wall facing the UWMS property is only 0.5 feet high, providing minimal visual impact. In addition, the wall is situated at the rear of the UWMS property behind the proposed building. The remaining wooded area, and the rear parking area will also help mitigate visibility from the road and the adjoining residences. 137

10 Tree removal for the retaining wall is also limited. Only ten trees are proposed to be removed on the side of the retaining wall facing the Con Edison property. While trees on the UWMS side of the wall are to be removed, they would have had to have been removed regardless of the creation of the proposed retaining wall in order to construct the proposed rear parking lot. As discussed in Section III.C.2.b, the overall site design requires approximately 6,300 cubic yards of borrow. The source of the 6,300 cubic yards of borrow will depend on what other construction projects are in operation within the area at the time. Whichever project that has suitable excess material at the closest distance to the Project at a suitable price will be utilized. e. Proposed Demolition of Existing Buildings, Structures, Driveways and Parking Areas, And The Effect Of Such Impacts, Including But Not Limited To Testing For Hazardous Materials And The Removal Of Construction Debris A qualified asbestos abatement contractor will be retained to test for and abate any asbestoscontaining materials identified prior to the commencement of any demolition work on the existing structures on the Property to be removed. Any abatement work will be performed in a manner that complies with the applicable Occupational Safety and Health Administration (OSHA-29CFR ), Environmental Protection Agency (EPA- 40CFR 61 Subpart M), and New York State Department of Labor (Title 12, Part 56) regulations: The selected asbestos abatement contractor will: Perform an asbestos survey of the proposed structures to identify any potentially asbestos-containing materials. 138

11 Prepare an Asbestos Abatement Plan in accordance with federal, state, and/or local requirements if asbestos is determined to be present. This plan will address the following: -Method of removal; -Protection of the public, workers and environment from airborne asbestos fibers; and -Disposal. Notify the New York State Department of Labor 10 days prior to the start of asbestos abatement activities. Abate all asbestos-containing materials that have been identified during the contractor s asbestos survey. Provide a certification that all asbestos-containing materials that were identified both during the contractor s survey and any additional materials that were encountered during the abatement process have been abated. The Applicant intends to "deconstruct" the existing buildings (instead of demolition) so that material that can be recycled is separated out of the general disposed material. Demolition (or deconstruction) activities, if performed without controlled provisions, have the potential to generate and transmit dust and debris to surrounding areas. Building and structure deconstruction will be performed in a systematic fashion, starting with the removal of building interiors. Deconstruction would then proceed to the removal of the building skin, structure, foundation systems and ending with the removal of underground utilities. During the course of deconstruction, protective measures will be taken to limit the potential for dust generation, specifically through use of misting water and/or other systems. Protective measures are specifically important when addressing the removal and break-up of concrete foundation systems. 139

12 f. Use Of Excavated Soils and Materials, And Procedures For Removal Of Excess Material From The Site, If Applicable Topsoil removed as a result of construction will be stockpiled for later use in the landscape areas. Following final grading, topsoil will be spread and the ground surface revegetated promptly using trees, shrubs, and perennials as set forth in the landscape plan. Subsoil and/or suitable gravel will be reclaimed on the site to the maximum extent practicable. Unsuitable material would be removed. The site design earthwork analysis indicates a net borrow of 5,200 cubic yards. g. Evaluate Compliance With All Applicable Provisions Of Chapter 108 (Steep Slope Protection) Of The New Castle Town Code Chapter 108 of the Code of the Town of New Castle, entitled Slope Protection regulates the disturbance of steep slopes to preserve, protect and conserve steep slopes, and properly manage and control disturbance of steep slopes. The proposed development plan impacts approximately 10,488 square feet of weighted regulated steep slope area (Figure I.A-9), which is below the minimum 13,068 square foot steep slope disturbance threshold for requiring a Steep Slope Permit in connection with steep slope disturbance or elimination. However, a Steep Slope Permit will be required from the Planning Board because steep slopes are proposed to be created. The less steep portions of the Property encompass local wetlands and wetland buffer areas, which are also considered environmentally sensitive areas. Because of the environmentally sensitive local wetland and buffer areas, combined with the narrow shape of the Property, there is no practicable alternative to such slope disturbance, and such disturbance constitutes the minimum disturbance necessary to ensure the reasonable use of the Property. 140

13 The disturbance to the slopes will be managed to minimize additional erosion to the maximum extent practicable, while not adversely affecting the preservation of the existing locally regulated wetlands or proposed or potential future sewage disposal systems. The slopes are of such a limited extent (Figure I.A-10) that slope creep or sudden slope failure is not considered an issue. In addition to not disturbing the archeological area on the southeastern portion of the Property, by limiting the extent of the proposed parking lot to 170 spaces rather than the 217 required for events such as the two annual Islamic Holiday celebrations, the Applicant avoids impacts to existing steep slopes within this area (Figure III.C-1). 3. Proposed Mitigation a. Discuss Sediment and Erosion Control Plan Prepared In Accordance With The Latest Edition Of The New York Guidelines For Erosion and Sediment Control ("Blue Book") And The Latest Edition Of The New York State Department of Environmental Conservation Publication, Stormwater Management Design Manual A conceptual Sediment and Erosion Control Plan is depicted in Figure II.E-1. Development of the proposed Project could potentially result in erosion and the transport of sediment during construction without the utilization of proper erosion and sediment controls. Erosion and sediment controls for the Project will be designed to meet or exceed the criteria of the New York State Department of Environmental Conservation SPDES General Permit No. GP for Stormwater Discharges from Construction Activities. An Erosion and Sediment Control Management Program will be established for the proposed development, beginning at the start of construction and continuing throughout its course, as outlined in the "New York State Standards and Specifications for Erosion and Sediment Control," dated August A continuing maintenance program will be implemented for erosion and sediment control after construction. The Applicant will have a qualified professional conduct an assessment of the Site prior to the commencement of 141

14 construction and certify that the appropriate erosion and sediment controls have been adequately installed to ensure overall preparedness of the Site for the commencement of construction. In addition, the Owner will have a qualified professional conduct Construction Duration Inspections at least every seven calendar days. On-Site Pollution Prevention Pollution prevention measures are proposed to control litter and construction debris on the Site. Devices will be placed at the bottom of the temporary sediment basin where they intercept and collect debris and litter before they can enter the off-site storm system. There will be inlet protection provided for all storm inlets with the use of curb gutter inlet protection and stone and block drop inlet protection, which keep silt, sediment and construction litter and debris out of the on-site stormwater drainage system. All construction material will be stored in designated staging areas. Roll-off containers are to be placed on-site and all empty containers, construction debris and litter is to be placed in the containers. The General Contractor for the Project will have a spill prevention and response plan, as well as materials on-site to remediate a spill. Sequence of Construction All construction is to be completed within one phase. No more than approximately 3.6 acres of the Site will be disturbed, in accordance with the New York State Department of Conservation (NYSDEC) SPDES requirement that no more than five (5) acres of soil be disturbed at any given time. 142

15 The following describes the Sequence of Construction which is to be followed: 1. Install a stabilized construction entrance and all silt fence. Clear the area to be developed. 2. Grub the area for the construction of the temporary sediment basin and strip and stockpile the topsoil. Construct the basin and stabilize the area disturbed for the construction of the Temporary Sediment Basin in accordance with the Plans. 3. Grub the areas to be constructed which are defined as the area of active construction. 4. Remove and stockpile topsoil from the area under active construction. Install silt fencing around the temporary topsoil stockpile location(s) for erosion control purposes. 5. Proceed with rough grading of the area under active construction, including construction of temporary diversion swales and stone check dams as required to convey stormwater runoff to the temporary sediment basin. Exposed areas will be stabilized as soon as practicable. 6. Install the storm drainage system consisting of catch basins, manholes and underground storm pipes from the Stormwater Management Basin (Temporary Sediment Basin) through the area of active construction along with the sediment and erosion control devices associated with the storm drainage system (i.e. inlet protection, stone check dams, etc., as shown on the Plans) in order to ensure that runoff from the area will be conveyed to the Temporary Sediment Basin. 7. Install public utilities (gas, electric, telephone, etc.), as required. 8. Begin building and parking lot construction including foundations, curb, and subbase and base pavement sections. 143

16 9. Finish grading, redistribute topsoil and establish vegetation and/or landscaping. 10. Clean pavements and storm drain system of all accumulated sediment in conjunction with the removal of all temporary sediment and erosion control devices. Remove sediment from the temporary sediment basin, excavate to final proposed grades, install basin vegetation and stabilize. 11. Complete site construction in area of active construction. Temporary Control Measures Throughout construction of the Project, temporary control facilities will be implemented to control on-site erosion and sediment transfer. Interceptor swales will be used to direct stormwater runoff to the temporary sediment basin for settlement. The stormwater management area to be constructed as part of this Project will serve as a temporary sediment basin to remove sediment and pollutants from the stormwater runoff produced during construction. Descriptions of the temporary sediment & erosion controls that will be used during the development of the Site including silt fence, stabilized construction entrance, seeding, mulching, inlet protection and stone check dams are as follows: 1. Silt Fence is constructed using a geotextile fabric. The fence will be either 18 inches or 30 inches high. The height of the fence can be increased where these devices are utilized on uncompacted fills or extremely loose undisturbed soils. The fences will not be placed in areas which receive concentrated flows such as ditches, swales and channels nor will the filter fabric material be placed across the entrance to pipes, culverts, spillway structures, sediment traps or basins. 144

17 2. Stabilized Construction Entrance consisting of 1 to 4 inch sized stone. The entrance will be a minimum of 50 feet in length by 24 feet in width by 6 inches in depth. 3. Seeding will be used to create a vegetative surface to stabilize disturbed earth until at least 70% of the disturbed area has a perennial vegetative cover. This amount is required to adequately function as a sediment and erosion control facility. Grass lining will also be used to line temporary channels and the surrounding disturbed areas. 4. Mulching will be used as an anchor for seeding and disturbed areas to reduce soil loss due to storm events. These areas will be mulched with straw at a rate of 3 tons per acre such that the mulch forms a continuous blanket. Mulch will be placed on all exposed areas within 48 hours. 5. Inlet Protection will be provided for all stormwater inlets with the use of curb gutter inlet protection and stone & block inlet protection structures, which will keep silt, sediment and construction debris out of the storm system. 6. Temporary Swales will be installed to intercept sediment laden water and divert it to a sediment trapping device. 7. A Temporary Sediment Basin will be installed to intercept sediment laden runoff and to trap and retain the sediment. The sediment basin will be sized to provide a sediment storage volume of 3,600 cubic feet per acre draining to the basin. Temporary sediment & erosion control measures will be maintained throughout construction. This maintenance will include but not be limited to the following tasks: 9. For dust control purposes, all exposed graded areas will be moistened with water at least twice a day in those areas where soil is exposed and cannot be planted with a temporary cover due to construction operations or the season (December through March). 145

18 10. Inspection of erosion and sediment control measures will be performed at the end of each construction day and immediately following each rainfall event. All required repairs will be immediately executed. 11. Sediment deposits will be removed when they reach approximately 1/3 the height of the silt fence. All such sediment will be properly disposed of in fill areas on the Site. Fill will be protected following disposal with mulch, temporary and/or permanent vegetation and be completely circumscribed on the downhill side by silt fence. 12. All exposed areas parallel to the slope will be raked during earthwork operations. 13. Following final grading, the disturbed area will be stabilized with a permanent surface treatment (i.e. turfgrass, pavement or sidewalk). During rough grading, areas which are not to be disturbed for fourteen or more days will be stabilized with the temporary seed mixture, as defined on the plans. Piles of dirt in exposed soil areas that will not receive a permanent surface treatment will be seeded. b. Additional Features of The Proposed Site Plan That Reflect Steps Taken To Avoid, Minimize or Mitigate Potential Impacts On Existing Topography and Town-Regulated Steep Slopes No additional mitigation measures are proposed. 146
