A copy of this permit is provided in Appendix A of this report for reference. II - Proiect Summary: The Koehler Family Limited Partnership project is a proposed land subdivision of a 14.94 ac. parcel of land located at 4180 New Suffolk Avenue, on the southeast corner of Marratooka Road and New Suffolk Avenue in Mattituck. The initial phase of the project is to construct a 50' wide public road providing access to each of the proposed residential subdivision lots as delineated in the Clustered Final Plat dated 3- 20 -18, by Kenneth M. Woychuk Land Surveying, PLLC. of Aquebogue. In accordance with the requirements of this Stormwater Pollution Prevention Plan (SWPPP), an Erosion and Sediment Control Plan was prepared by Grammas Consultants to illustrate the means by which pollutants and runoff from the site may be controlled before, during and after all construction activities. The proposed Stormwater Pollution Prevention Plan includes stormwater retention and management, in addition to erosion and sediment control measures during construction for phase one. Individual subdivision lots propose stormwater retention, management, and erosion and sediment control measures for subsequent phases of the remaining total site project.

Cala, R.A. 208 Route 109, Suite 208, Farmingdale, New York 11735 Tel.: 631.393.6805 Dominion Construction Corp. - Contractors & Sub - Contractors Contact Person: John Koehler 108 Allen Blvd., Farmingdale, New York 1 1735 Tel.: 63 1.249.0888 IV - Existing Site Description General Description — The existing parcel is located on approximately 14.94 acres at 4180 New Suffolk Avenue, in Mattituck, Town of Southold, Suffolk County, New York. The Suffolk County Tax Map Number is District 1000, Section: 115.00, Block: 10.00, Lot: 001, and is designated as a Residential Zone R -80 property. The site is predominately undeveloped, vacant land situated on the southeast corner of New Suffolk Avenue and Marratooka Road, Mattituck, New York. it is a predominately open, vacant parcel, which include bluffs, wetland and easements, and an existing 1 story residential home and a garage structure equal to approximately 1.20 ac. of the total site. To the best of our knowledge, a combination of ground shrubs and assorted trees comprise this area leading to and surrounding the bluffs and wetlands, and the existing residential structure. A utility easement is included in this area. Presently, the composition of the land coverage correlates to a 0.01 % impervious area over the entire property. A majority of the existing topography of the site is moderately sloped from the east boundary of the property to the west at a grade of approximately 0 - 2 %. However, slopes at the bluff and wetland area are upwards of 15 %. There does not appear to be any stormwater management facilities currently located on the property. Stormwater from a rainfall event will either pond at localized low points to be recharged into the ground or runoff the property. Wetlands and waterbody areas are on or adjacent to the site. The nearest surface water body is Deep Hole Creek, on the eastern edge of the project site. According to the FEMA Flood Hazard Maps, no portion of the site lies within a federally determined flood plain as per FEMA Map No.: 36103C0482H (Appendix A). V - On -Site Soil Conditions The USDA Web Soil Survey of Suffolk County classifies the soil on the subject property as UaA - Haven loam ( +/- 50.5 %), RdB — Riverhead sandy loam ( +/- 42.0), and PIC — Plymouth loamy sand ( +/- 7.5 %) . For the purpose of conducting a hydrologic analysis, the Hydrologic Soil Group of the soils on -site are assumed adequate to allow for stormwater infiltration. (See Soil Map Appendix A). VI - Proposed Project As indicated previously, this project proposes the development of a public road and seven residential subdivision lots with associated site work on a 5.02 acre of the site fronting on New Suffolk Avenue. The proposed public road and public water service will be connected to existing service along New Suffolk Avenue. This project also proposes a permanent on -site stormwater management system for both the public road, and for each individual residential lot. The proposed stormwater management system for the public road will consist of a total of 8 precast concrete drywells located at the midpoint and the end of a proposed cul -de -sac. Stormwater will be directed from New Suffolk Avenue and adjacent landscaped areas to low points graded into the edge of pavement and grassland areas adjacent to the pavement and to be collected by either the drywells or catch basin inlets. Stormwater from impervious areas of the roof and driveway of each individual lot will be piped directly to drywells sized accordingly by lot for the proposed residential structures and access drives. This proposed stormwater management system will capture and treat the stormwater runoff from a 2" rainfall, as directed by Town of Southold standards. The following Table summarizes the proposed land uses for the property. Coverage Pavement Landscaping Residential Buildings Total Impervious Total Landscaping Total Site Site Land Uses Area (S.F.) 23,473 179,365 15,800 39,273 179,365 218,638 Area (AC.) 0.539 4.117 0.363 0.902 4.117 5.019 As discussed, the area of disturbance for the total project is approximately 218,638s.f., or 5.02 acres. Construction will proceed in the following manner: Phase 1: • Installation of temporary soil and erosion control measures (perimeter silt fence barriers, perimeter swales, straw bales, existing offsite inlet protection, and stabilized construction entrance). • Clearing and grubbing of on -site disturbance area. • Rough grading of the proposed pavement and adjacent surfaces. • Installation of drainage structures, utilities and water lines. • Installation of proposed curb and final grading. • Paving of public road for Phase 2 construction access. • Removal of the erosion control measures as necessary for Phase 2. Phase 2: • Installation of temporary soil and erosion control measures for individual lots (perimeter silt fence barriers, perimeter swales, straw bales, existing offsite inlet protection, and stabilized construction entrance). • Clearing and grubbing of individual lot disturbance area. • Rough grading of the proposed pavement and building surfaces. • Installation of drainage structures, utilities, sanitary structures and water lines. • Construction of building foundation and concrete slab. • Construction of the proposed building. • Paving of proposed driveway access and final grading. • Seeding and installation of landscaping. • Final removal of the erosion control measures. The phasing described above is to be considered general. Actual construction phasing and timelines are to be determined by the contractor at the tirne of construction. Erosion control measures are to be installed as their need becomes appropriate. For example, the construction entrance is to be installed at the beginning of construction; while inlet protection is to be installed as the stormwater inlets are installed. VII — Stormwater PlanninLF Process: The stormwater management system for the site is designed to capture and treat the Water Quality Volume (WQv), which represents 90% of the average annual stormwater runoff volume rainfall as per the standards of the Town of Southold. The proposed stormwater management system will consist of a total of twenty-three (23) precast concrete drywells, providing an approximate total on -site storage capacity of 6,751 CF. The site's drainage system is composed of ten sub - drainage areas that collect stormwater from their respective tributary shed areas through proper grading of the ground surface. Once collected by the drywell and catch basin inlets, stormwater will be stored and eventually recharged into the surrounding soils, thereby reducing the peak runoff of stonnwater from the site. Refer to the Stormwater Prevention and Drainage Plans by Grammas Consultants for the calculations and details on the locations of inlets and sizing of the drainage structures. The stormwater runoff for the pre and post developed site conditions were calculated using the criteria for runoff reduction and stormwater management practices as outlined in the New York State Stormwater Management Design Manual. As determined, the peak flow of stormwater runoff will increase due to construction of the proposed development. This is due to the increase in the amount of impervious surface on the site. To account for the increase in runoff during heavy rain events, the project is proposing a stormwater management system comprised of precast concrete drywell structures to detain and recharge the required volume of water. These structures provide retention and recharge capabilities for the proposed public road, as well as the individual lots. In accordance with the NYS DEC requirements, the project is required to capture and treat the Water Quality Volume (WQv) which represents 90% of the average annual stormwater runoff volume. As shown in the formula below, the WQv for this site is 5,772 CF (.132 acre -ft). The total storage volume of the drywells provided by this project is 6,751 CF (0.154 acre -ft), which is greater than the Water Quality Volume. The following equation was used to determine the above water quality storage volume WQv (in acre -feet of storage): WQv = (P x Rv x A) /12 Rv = 0.05 +.009 *I where: P = 90% Rainfall Event = 1.5 inches Rv = 0.05 + 0.009 1 where: I= Percent Impervious Cover= 17.95% A = Area (acres) = 5.02 acres WQv = (1.5 x 0.05 +(0.009 x 17.95) x 5.02)/12 = 1.5 x 0.2115 x 5.02/12 = 1.59/12 = 0.132 acre -feet (5,772 cf) Next, the Runoff Reduction Volume (RRv) was calculated by comparing the proposed stormwater management practices to the Water Quality Volume (WQv) of the site. In accordance with the DEC, infiltration of stormwater is considered a best management practice for runoff reduction and 90% of the system's capacity can contribute to the runoff reduction volume. As such, the runoff reduction volume for this project is 6,076 CF. This calculation demonstrates that the proposed stormwater management system provides runoff reduction volume that exceeds the water quality volume stated above. VIII — Notice of Intent: Prior to the start of construction, the property owner or operator must submit a Notice of Intent (NOT) to the New York State Department of Environmental Conservation in order to discharge stormwater associated with construction activity under the SPDES General Permit #GP -0 -20 -001 for Stormwater Discharges. A copy of the completed NOT is provided in Appendix D of this report. IX - Erosion & Sediment Control Practices: Design Criteria: The proposed erosion and sediment control practices shall be installed and maintained throughout construction in accordance with the New York Standards and Specifications for Erosion and Sediment Controls, the New York State Stormwater Management Design Manual and the approved Stormwater Pollution Prevention Plans provided herein. Refer to the Erosion Control plans prepared by Grammas Consultants for additional information (see Appendix B). Prior to the initial construction phase of this project, and applied to subsequent phases, temporary and permanent soil erosion measures shall be undertaken to minimize any impacts to the site and the surrounding land areas. These measures will be in accordance with the design specifications and maintenance requirements as stated and outlined in Appendix G. The following erosion and sediment control measures shall be utilized during and after construction of this project. Erosion and Sediment Planning: Pre - Construction Actions - Prior to any construction of the proposed development project, the following measures will need to be taken to ensure the surrounding areas will not be affected. • installation of a construction fence, silt fence, temporary swale, straw bale and dust control measures along the perimeter of the site as applicable, and around the area of each individual phase as each progress. • installation of one (1) temporary stabilized crushed stone construction entrance to the site, and for each consecutive phase of lot construction. • Stabilization of high traffic construction areas within the site. All earthwork activities shall not commence until all initial sediment control measures have been installed. Any topsoil removed during clearing from the site shall be stockpiled on site. This stockpiled soil will be located away from the required buffer zones, and will be stabilized, protected, and secured for reuse. Erosion Control - During the land clearing phase of the development project, soil erosion at the site will be controlled by: • Keeping all disturbed areas to a rninimum and to provide temporary seeding and mulching, or jute mesh to control stormwater runoff and to prevent excess erosion. • Keeping any topsoil stockpiles less than 20 feet in height, and keeping side slopes of these stockpiles at or less than 2:1 Sediment Control - During the land clearing phase of the development project, sediment control at the site will be controlled by: • installing silt fence barriers and straw bales around the perimeter of the site, along the perimeter of each outlined phase, and along the base of any stockpiled topsoil. • Placing curb inlet filters over all affected grates of the stormwater conveyance system along the new public road during subsequent phases. • Cleaning of inlet filters and all silt control measures after each erosion producing storm, or when capacity has been reduced by 50 percent. • Use of temporary runoff control /sediment basins at each lot phase locations within the site. Drainage_ Control - To the best of our knowledge, the existing site does not generally produce any significant runoff offsite, nor does it take in any considerable additional runoff from surrounding properties. This can be attributed to the surrounding topography of adjacent developed and undeveloped properties. Any runoff which will be generated due to construction activities on site will be diverted through a means of temporary swales into the temporary runoff control /sediment basins (Refer to SWPP drawings for locations). Upon completion of each phase of construction, an approved stormwater conveyance system will be initiated. This system will consist of a series of roof leaders and catch basins, routed by means of a piping system, to convey stormwater into drywells for disbursement into the ground. Each phase of the site will be graded such that surface runoff flows to the various drainage system inlets. These inlets will be properly protected to provide sediment control as required for each phase. Maintenance and Inspection — Soil erosion and sediment control shall be ensured during the land clearing and the future construction period. This will be accomplished through a program of daily observation and maintenance with a particular emphasis on inspections and repair following any rainfall greaterthan 0.5 inches, All graded areas of the site shall be temporarily seeded as previously discussed to minimize site erosion. During the future construction phases of the development project, the responsibility of maintenance actions shall fall upon the contractor. Once all construction is completed, maintenance of the property shall continue by the applicant, owner, or their representative, and copies of the inspections and quarterly reports shall remain on -site with this SWPP. Post Construction Controls— Upon completion of the development project, all open areas must be stabilized with post construction measures and controls, and all temporary control measures are to be removed. These measures shall be implemented upon completion of each lot construction phase to provide regrading, and areas of permanent top soil, seed or sod, and mulch, including appropriate approved plantings, to further stabilize and maintain each developed phase. The contractor is not limited to these measures and may provide any additional measures as applicable during construction. `i - Good Housekeeping Practices: Good housekeeping and material management practices shall be utilized on -site during each construction phase of the project to reduce the risk of spills and other accidental exposure of materials and substances to stormwater runoff. Waste materials including packaging, pallets, discarded materials, etc. will be collected and disposed of into a metal trash dumpster in an area designated for that purpose. The dumpster will be placed away from all stormwater conveyances and drains, have a secure, watertight lid, and meet all federal, state and municipal regulations. Only trash and construction debris from the site will be deposited in the dumpster. At no time will construction materials be buried on -site. A temporary sanitary facility (portable toilet) will be provided at the site throughout the construction. Portable toilets will be located away from concentrated traffic flow paths, and will have collection pans underneath as secondary containment. Several types of vehicles and equipment will be used on -site throughout the construction project, including graders, scrapers, excavators, loaders, paving equipment rollers and backhoes. All major equipment /vehicle fueling and maintenance will be performed off site. When fueling must occur on -site, the fueling activity will occur in the staging area. Only minor equipment maintenance will occur on site. Any equipment fluids generated from this activity will be disposed of into designated drums stored in spill pallets. Absorbent, spill clean -up materials and spill kits will be available at the staging area. Drip pans will be placed under all equipment receiving maintenance, and equipment parked overnight. X1 —Inspection Schedtile: Site inspections of the project shall be conducted in accordance with the SPDES General Permit for Stormwater Discharges Associated with Construction Activities. It is the responsibility of the property owner to ensure that the inspection practices and procedures of the SWPPP are properly implemented. These procedures include, but are not limited to: Having a qualified professional conduct an assessment of the site prior to the commencement of construction activities, and to certify in an inspection report that the appropriate erosion and sediment controls as described in the SWPPP have been adequately installed or implemented to ensure the overall preparedness, integrity and effectiveness of the site for the commencement of construction. Having a qualified professional conduct regular site inspection activities at least once every seven (7) days when soil disturbance activities are ongoing to ensure any deficiencies regarding erosion and sediment control are reported and corrected. Having an inspection within 24 hours of any storm event producing 0.5 inches of precipitation or more. Inspection of the proposed erosion control measures shall take place as necessary in accordance with the most current version of the New York Standards and Specifications for Erosion and Sediment Control. Maintenance on the proposed erosion control measures shall take place as follows: 1. Stabilized Construction Entrance — The Contractor shall inspect stabilized entrances after each rainfall. The entrance must be maintained in such a way as to prevent any tracking or sediment flow off -site. 2. Silt Fence — The Contractor shall remove silt and sediment material from the project side of the silt fence as necessary or as directed by the Engineer. 3. Sediment Control at Drainage Inlets — The Contractor shall inspect and clean sediment control measures after every storm event or as directed by the Engineer. Sediment impeding flow of clean stormwater runoff to the basins shall be removed. 10 Inspection and maintenance of the permanent on -site stormwater control measures will consist of periodic maintenance and inspection of the on -site drainage system. The inlets are to be clean and free of debris to ensure proper functioning. The drywell system will be cleaned periodically to ensure its leaching ability into the surrounding soil. The owner of the project will be responsible for ensuring the inspection and maintenance of the onsite drainage system. Documentation of the effectiveness of all erosion and sediment control practices shall be in the form of inspection reports. Inspection reports are to be maintained on -site at all times and made available to the authorities upon request. The inspector must notify the owner /operator of any required corrective actions, and these actions must be addressed and implemented within one business day of notification. X11— Operation and Maintenance: Post - Construction Stormwater Management Practices Post - Construction Stormwater Management Practices consist of twenty -three (23) precast concrete drywells outfitted with area inlets, as well as catch basins and distribution boxes which comprise the site drainage system and serve to collect and infiltrate the stormwater runoff from the development into the soils. Required Maintenance The maintenance required for proper operation of the Post - Construction Management Practices generally consists of cleaning the structures and keeping storm drainage inlets free of debris. Debris should be removed from drywells which are fitted with inlet castings (see below). Maintenance Schedule In general, unless extreme conditions dictate, the following schedule should be followed for maintenance of the various components of the storm drainage system: • Drywells and Catch Basins — inspect and remove sediment and debris at a rninimurn of twice per year, and clean as necessary once per year, preferably in the winter (after leaves have fallen). Inspect and clean inlet castings as necessary. Sediment shall be removed by vacuum truck or comparable equipment as necessary. XIV — Notice of Termination: The Notice of Termination included with this document (Appendix H) is to be completed and submitted to the New York State Department of Environmental Conservation at the conclusion of construction in accordance with the general permit.

Purpose This appendix lays out a series of minimum requirements for erosion and sediment control, and management practices that may be used to meet these requirements. Use of these templates will help show compliance with the general requirements for construction activities that require basic stormwater pollution prevention plans ( SWPPP). This applies to the construction of small homesites. The owner/ developer must complete the relevant conditions (1 -4), or small parcel erosion and sediment control plan included in this section, and submit the NOI in order to meet compliance with the SPDES General Permit for Stormwater Discharges From Construction Activities. Criteria Generally, several types of practices are required on any one site for effective erosion and sediment control. There are three broad categories of construction- related practices for controlling erosion and sediment on small homesite developments: over practices prevent erosion by protecting the soil surface from rainfall and runoff. Prevention of erosion is the most preferable and cost - effective approach. These practices include: protection of existing vegetation; temporary covering of exposed soil by mulching, matting, or covering; and permanent site stabilization by topsoiling, seeding, and /or sodding. 2. Structural Practices are structural controls that either reduce erosion, control runoff, or keep sediment on the construction site. Examples of these practices include stabilized construction entrances, silt fences, sediment traps, berms, and check dams. Management Measures are construction management methods that prevent or reduce erosion potential and ensure the proper functioning of erosion and sediment control practices. Careful construction management can dramatically reduce the costs associated with erosion and sediment problems. Examples of these management measures include: • Preserving existing trees and grass where possible to prevent erosion; • Decompacting and re- vegetating the site as soon as possible; • Locating soil piles away from roads or waterways; • Limiting tracking of mud onto streets by requiring all vehicles to use designated access drives; • Removing sediment carried off -site by vehicles or storms; • Installing downspout extenders to prevent erosion from roof runoff, and • Maintaining erosion and sediment practices through sediment removal, structure replacement, etc. Specifications Each construction site is different. The owner /developer of a small construction site may choose and follow one of the four variations of ESC plans included in this section to develop a SWPPP in compliance with the SPDES Construction Permit For Stormwater Discharges From Construction Activities. However, because of the general nature of the following conditions, the plans included in this section may not cover all of the resource protection needs on a particular site, and this form does not exempt an owner from the responsibility of filing an NOI, if required. Small Homesite Minimum Requirements: 1. Stabilized Construction Entrance: To prevent vehicles and equipment from tracking sediment and mud off -site, apply gravel or crushed rock to the driveway area and restrict traffic to this one route. This practice will help keep soil from sticking to tires and stop soil from washing off into the street. Carry out periodic inspections and maintenance including washing, top - dressing with additional stone, reworking, and compaction. Plan for periodic street cleaning to remove any sediment that may have been tracked off -site. Remove sediment by shoveling or sweeping and transport to a suitable disposal area where it can be stabilized. 2. Stabilization of Denuded Areas: In areas where soil disturbance activity has temporarily or permanently ceased, the application of soil stabilization measures must be initiated by the end of the next business day and completed within fourteen (14) days from the date the current soil disturbance activity ceased. For construction sites that directly discharge to one of the 303 (d) segments listed in the Construction General Permit or is New York State Standards and Specifications Page D.I November 2016 For Erosion and Sediment Control located in one of the watersheds listed in Appendix C, the application of soil stabilization measures must be initiated by the end of the next business day and completed within seven (7) days from the date the current soil disturbance activity ceased. Stabilize disturbed areas by implementing soil covering practices (e.g. mulching, matting, sodding). Exposed soils are the most prone to erosion from rainfall and runoff. Vegetation helps protect the soil from these forces and provides natural erosion control. Plan construction to limit the amount of exposed area, and avoid grading activities during the rainy season (November through March) as much as possible. Clearing limits should be clearly marked and kept as small as possible. Once construction is completed, the site must be permanently stabilized with topsoiling, seeding and plantings, or sodding if needed. 3. Protection of Adjacent Properties: Keep sediment on -site by using structural and source control practices (e.g. vegetative buffer strips, sediment barriers, soil berms or dikes, etc). See Sections 3, 4, or 5 as appropriate. Wherever possible, preserve a buffer of existing vegetation around the site boundary. This will help to decrease runoff velocities and trap sediment suspended in the runoff. Other structural controls such as filter fence or straw bale barriers should also be used to filter runoff and trap sediment on -site. When excavating basement soils, move the soil to a location that is, or will be, vegetated, such as in the backyard or side yard area. This will increase the distance eroded soil must travel, through vegetation, to reach the storm sewer system. Piles should be situated so that sediment does not run into the street or adjoining yards. Soil piles should be temporarily seeded and circled with silt fence until the soil is either replaced or removed. Backfill basement walls as soon as possible and rough grade the lot. This will eliminate the large soil mounds, which are highly erodible, and prepare the lot for temporary cover. After backfilling, grade or remove excess soil from the site quickly, to eliminate any sediment loss from surplus fill. 4. Concentrated Flow: For constructed drainage ways, or other areas of concentrated flow, install check dams according to the specifications on page E.12 to reduce erosion in the channel. As with other erosion controls, check dams must be inspected regularly. Remove sediment accumulated behind the dam as needed to allow channel to drain through the stone check dam and prevent large flows from carrying sediment over the dam Replace stones as needed to maintain the design cross section of the structures. Sediment removal is crucial to the effectiveness of the dam —if not maintained, high flows could cause erosion around the sides of the structures, adding significant sediment loads downstream. 5. Maintenance: Maintain erosion and sediment control practices through regular inspection. Regular maintenance is extremely important for the proper operation of structural practices. After initial groundbreaking, the responsible contractor shall conduct daily maintenance inspections within the active work area to ensure practices are being maintained in effective operating conditions at all times. 6. Soil Restoration: Soils that have been disturbed and compacted due to construction activities should be de- compacted to restore their previous hydrologic condition. This normally involves aeration of small areas for home sites. Large areas should be restored in accordance with the Soil Restoration standard in Section 4 of this book of standards. 7. Other Practices: Use additional practices as required by the local plan approval authority to mitigate effects of increased runoff. This may include providing additional controls to a locally protected stream or resource area, protecting riparian corridors (vegetative stream buffers), etc. Individual homeowners and /or developers are responsible for researching additional requirements related to erosion and sediment runoff control established by their local jurisdictions.

In order to preserve existing vegetation determined to be important for soil erosion control, water quality protection, shade, screening, buffers, wildlife habitat, wetland protection, and other values. Conditions Where Practices Applies On planned construction sites where valued vegetation exists and needs to be preserved. Design Criteria 1. Planning Considerations A. Inventory: 1) Property boundaries, topography, vegetation and soils information should be gathered. Identify potentially high erosion areas, areas with tree windthrow potential, etc. A vegetative cover type map should be made on a copy of a topographic map which shows other natural and manmade features. Vegetation that is desirable to preserve because of its value for screening, shade, critical erosion control, endangered species, aesthetics, etc., should be identified and marked on the map. 2) Based upon this data, general statements should be prepared about the present condition, potential problem areas, and unique features of the property. B. Planning: 1) After engineering plans (plot maps) are prepared, another field review should take place and 2) Areas to be seeded and planted should be identified. Remaining vegetation should blend with their surroundings and /or provide special function such as a filter strip, buffer zone, or screen. 3) Trees and shrubs of special seasonal interest, such as flowering dogwood, red maple, striped maple, serviceberry, or shadbush, and valuable potential shade trees should be identified and marked for special protective treatment as appropriate. 4) Trees to be cut should be marked on the plans. If timber can be removed for salable products, a forester should be consulted for marketing advice. 5) Trees that may become a hazard to people, personal property, or utilities should be removed. These include trees that are weak - wooded, disease - prone, subject to windthrow, or those that have severely damaged root systems. 6) The vigor of remaining trees may be improved by a selective thinning. A forester should be consulted for implementing this practice. 2. Measures to Protect Vegetation A. Limit soil placement over existing tree and shrub roots to a maximum of inches. Soils with loamy texture and good structure should be used. B. Use retaining walls and terraces to protect roots of trees and shrubs when grades are lowered. Lowered grades should start no closer than the dripline of the tree. For narrow - canopied trees and shrubs, the stem diameter in inches is converted to feet and doubled, such that a 10 inch tree should be protected to 20 feet. C. Trenching across tree root systems should be the same minimum distance from the trunk, as in "B ". Tunnels under root systems for underground utilities should start 18 inches or deeper below the normal ground surface. Tree roots which must be severed should be cut clean. Backfill material that will be in contact with the roots should be topsoil or a prepared planting soil mixture. D. Construct sturdy fences, or barriers, of wood, steel, or other protective material around valuable November 2016 Page 2.26 New York State Standards and Specifications For Erosion and Sediment Control saved. Minor adjustments in location of roads, ' dwellings, and utilities may be needed. Construction on steep slopes, erodible soils, wetlands, and streams should be avoided.

Place barriers far enough away from trees, but not less than the specifications in 'B ", so that tall equipment such as backhoes and dump trucks do not contact tree branches. E. Construction limits should be identified and clearly marked to exclude equipment. F. Avoid spills of oil /gas and other contaminants. G. Obstructive and broken branches should be pruned properly. The branch collar on all branches whether living or dead should not be damaged. The 3 yr 4 cut method should be used on all branches larger than two inches at the cut. First cut about one -third the way through the underside of the limb (about 6 -12 inches from the tree trunk). Then (approximately an inch further out) make a second cut through the limb from the upper side. When the branch is removed, there is no splintering of the main tree trunk. remove the stub. If the branch is larger than 5 -6 inches in diameter, use the four cut system. Cuts 1 and 2 remain the same and cut 3 should be from the underside of the limb, on the outside of the branch collar. Cut 4 should be from the top and in alignment with the 3rd cut. Cut 3 should be 1/4 to 1/3 the way through the limb. This will prevent the bark from peeling down the trunk. Do not paint the cut surface. H. Penalties for damage to valuable trees, shrubs, and herbaceous plants should be clearly spelled out in the contract. PROTECTING TREES IN HEAVY USE AREAS The compaction of soil over the roots of trees and shrubs by the trampling of recreationists, vehicular traffic, etc., reduces oxygen, water, and nutrient uptake by feeder roots. This weakens and may eventually kill the plants. Table 2.6 rates the "Susceptibility of Tree Species to Compaction." Where heavy compaction is anticipated, apply and maintain a 3 to 4 inch layer of undecayed wood chips or 2 inches of No. 2 washed, crushed gravel. In addition, use of a wooden or plastic mat may be used to lessen compaction, if applicable. New York State Standards and Specifications Page 2.27 November 2016 For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR SURFACE ROUGHENING Definition & Scope C. Make the vertical cut distance less than the horizontal distance, and slightly slope the horizontal position of the "step" to the vertical wall. D. Do not make vertical cuts more than 2 feet in soft materials or 3 feet in rocky materials. Grooving uses machinery to create a series of ridges and depressions that run perpendicular to the slope following the contour. Groove using any appropriate implement that can be safely operated on the slope, such as disks, tillers, spring harrows, or the teeth of a front -end loader bucket. Do not make the grooves less than 3 inches deep or more than 15 inches apart. 2.

Use trapping of sediment. grooving as described above to roughen the slope, if necessary. Conditions Where Practice Applies B. Do not back blade or scrape the final slope face. All construction slopes require surface roughening to facilitate stabilization with vegetation, particularly slopes steeper than 3:1. Design Criteria There are many different methods to achieve a roughened soil surface on a slope. No specific design criteria is required. However, the selection of the appropriate method depends on the type of slope. Methods include tracking, grooving, and stair - stepping. Steepness, mowing requirements, and /or a cut or fill slope operation are all factors considered in choosing a roughening method. Construction Specifications 1. Cut Slope, No mowing. A. Stair -step grade or groove cut slopes with a gradient steeper than 3:1 (Figure 4.18). B. Use stair -step grading on any erodible material soft enough to be ripped with a bulldozer. Slopes of soft rock with some soil are particularly suited to stair -step grading. 3. Cuts /Fills, Mowed Maintenance A. Make mowed slopes no steeper than 3:1. B. Roughen these areas to shallow grooves by normal tilling, disking, harrowing, or use of cultipacker- seeder. Make the final pass of such tillage equipment on the contour. C. Make grooves at least 1 inch deep and a maximum of 10 inches apart. D. Excessive roughness is undesirable where mowing is planned. Tracking should be used primarily in sandy soils to avoid undue compaction of the soil surface. Tracking is generally not as effective as the other roughening methods described. (It has been used as a method to track down mulch.) Operate tracked machinery up and down the slope to leave horizontal depressions in the soil. Do not back -blade during the final grading operation.

A� Definition & Scope The stabi I ization of temporary construction access routes, on -site vehicle transportation routes, and construction parking areas to control erosion on temporary construction routes and parking areas. Conditions Where Practice Apiplies All traffic routes and parking areas for temporary use by construction traffic. Design Criteria Construction roads should be located to reduce erosion potential, minimize impact on existing site resources, and maintain operations in a safe manner. Highly erosive soils, wet or rocky areas, and steep slopes should be avoided. Roads should be routed where seasonal water tables are deeper than 18 inches. Surface runoff and control should be in accordance with other standards. Road Grade — A maximum grade of 12% is recommended, although grades up to 15% are possible for short distances. Road Width — 12 foot minimum for one -way traffic or 24 foot minimum for two -way traffic. Side Slope of Road Embankment — 2:1 or flatter. Ditch Capacity — On -site roadside ditch and culvert capacities shall be the 10 yr. peak runoff. Composition — Use a 6 -inch layer of NYS DOT sub -base Types 1,2,3, 4 or equivalent as specified in NYSDOT Standard Specifications. Construction SDecifications 1. Clear and strip roadbed and parking areas of all vegetation, roots, and other objectionable material. 2. Locate parking areas on naturally flat areas as available. Keep grades sufficient for drainage, but not more than 2 to 3 percent. 3. Provide surface drainage and divert excess runoff to stabilized areas. 4. Maintain cut and fill slopes to 2:1 or flatter and stabilized with vegetation as soon as grading is accomplished. 5. Spread 6 -inch layer of sub -base material evenly over the full width of the road and smooth to avoid depressions. 6. Provide appropriate sediment control measures to prevent offsite sedimentation. Maintenance Inspect construction roads and parking areas periodically for condition of surface. Top dress with new gravel as needed. Check ditches for erosion and sedimentation after rainfall events. Maintain vegetation in a healthy, vigorous condition. Areas producing sediment should be treated immediately. New York State Standards and Specifications Page 2.23 November 2016 For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR STORM DRAIN INLET PROTECTION owl -4 y' Definition & Scone A temporary barrier with low permeability, installed around inlets in the form of a fence, berm or excavation around an opening, detaining water and thereby reducing the sediment content of sediment laden water by settling thus preventing heavily sediment laden water from entering a storm drain system. Conditions Where Practice Applie s This practice shall be used where the drainage area to an inlet is disturbed, it is not possible to temporarily divert the storm drain outfall into a trapping device, and watertight blocking of inlets is not advisable. It is not to be used in lace of sediment trapping devices. This practice shall be used with an upstream buffer strip if placed at a storm drain inlet on a paved surface. It may be used in conjunction with storm drain diversion to help prevent siltation of pipes installed with low slope angle. Types of Storm Drain Inlet Practices drainage area tributary to the inlet. The crest elevations of these practices shall provide storage and minimize bypass flow. Type I — Excavated Drop Inlet Protection This practice is generally used during initial overlot grading after the storm drain trunk line is installed. Limit the drainage area to the inlet device to 1 acre. Exca- vated side slopes shall be no steeper than 2:1. The mini- mum depth shall be I foot and the maximum depth 2 feet as measured from the crest of the inlet structure. Shape the excavated basin to fit conditions with the longest dimension oriented toward the longest inflow area to provide maxi- mum trap efficiency. The capacity of the excavated basin should be established to contain 900 cubic feet per acre of disturbed area. Weep holes, protected by fabric and stone, should be provided for draining the temporary pool. Inspect and clean the excavated basin after every storm. Sediment should be removed when 50 percent of the stor- age volume is achieved This material should be incorpo- rated into the site in a stabilized manner. Type 11— Fabric Drop Inlet Protection There are five (5) specific types of storm drain inlet protec- tion practices that vary according to their function, location, -- drainage area, and availability of materials: I. Excavated Drop Inlet Protection 11. Fabric Drop Inlet Protection III. Stone & Block Drop Inlet Protection IV. Paved Surface Inlet Protection V. Manufactured Insert Inlet Protection Design Criteria Drainage Area — The drainage area for storm drain inlets shall not exceed one acre. Erosion control /temporary stabi- lization measures must be implemented on the disturbed _ •w This practice is generally used during final elevation grad- ing phases after the storm drain system is completed. Limit the drainage area to 1 acre per inlet device. Land area slope immediately surrounding this device should not ex- ceed I percent. The maximum height of the fabric above the inlet crest shall not exceed 1.5 feet unless reinforced. The top of the barrier should be maintained to allow over- flow to drop into the drop inlet and not bypass the inlet to New York State Standards and Specifications Page 5.57 November 2016 For Erosion and Sediment Control unprotected lower areas. Support stakes for fabric shall be a minimum of 3 feet long, spaced a maximum 3 feet apart. They should be driven close to the inlet so any overflow drops into the inlet and not on the unprotected soil. Im- proved performance and sediment storage volume can be obtained by excavating the area. Inspect the fabric barrier after each rain event and make repairs as needed. Remove sediment from the pool area as necessary with care not to undercut or damage the filter fabric. Upon stabilization of the drainage area, remove all materials and unstable sediment and dispose of properly. Bring the adjacent area of the drop inlet to grade, smooth and compact and stabilize in the appropriate manner to the site. Type III — Stone and Block Drop Inlet Protection This practice is generally used during the initial and inter- mediate overlot grading of a construction site. Limit the drainage area to 1 acre at the drop inlet. The stone barrier should have a minimum height of 1 foot and a maximum height of 2 feet. Do not use mortar. The height should be limited to prevent excess ponding and bypass flow. Recess the first course of blocks at least 2 inches below the crest opening of the storm drain for lateral support. Subse- quent courses can be supported laterally if needed by plac- ing a 2x4 inch wood stud through the block openings per- pendicular to the course. The bottom row should have a few blocks oriented so flow can drain through the block to dewater the basin area. The stone should be placed just below the top of the blocks on slopes of 2:1 or flatter. Place hardware cloth of wire mesh with 1/2 inch openings over all block openings to hold stone in place. As an optional design, the concrete blocks may be omitted and the entire structure constructed of stone, ringing the outlet ( "doughnut "). The stone should be kept at a 3:1 slope toward the inlet to keep it from being washed into the inlet. A level area 1 foot wide and four inches below the crest will further prevent wash. Stone on the slope toward the inlet should be at least 3 inches in size for stability and 1 inch or smaller away from the inlet to control flow rate. The eleva- tion of the top of the stone crest must be maintained 6 inch- es lower than the ground elevation down slope from the inlet to ensure that all storm flows pass over the stone into the storm drain and not past the structure. Temporary dik- ing should be used as necessary to prevent bypass flow. The barrier should be inspected after each rain event and repairs made where needed. Remove sediment as necessary to provide for accurate storage volume for subsequent rains. Upon stabilization of contributing drainage area, remove all materials and any unstable soil and dispose of properly. Bring the disturbed area to proper grade, smooth, compact and stabilize in a manner appropriate to the site. Type IV — Paved Surface Inlet Protection u}:, -. This practice is generally used after pavement construction has been done while final grading and soil stabilization is occurring. These practices should be used with upstream buffer strips in linear construction applications, and with temporary surface stabilization for overlot areas, to reduce the sediment load at the practice. This practice includes sand bags, compost filter socks, geo -tubes filled with bal- last, and manufactured surface barriers. Pea gravel can also be used in conjunction with these practices to improve per- formance. When the inlet is not at a low point, and is off- set from the pavement or gutter line, protection should be selected and installed so that flows are not diverted around the inlet. November 2016 Page 5.58 New York State Standards and Specifica- tions For Erosion and Sediment Control The drainage area should be limited to 1 acre at the drain inlet. All practices will be placed at the inlet perimeter or beyond to maximize the flow capacity of the inlet. Practices shall be weighted, braced, tied, or otherwise anchored to prevent movement or shifting of location on paved surfaces. Traffic safety shall be integrated with the use of this prac- tice. All practices should be marked with traffic safety cones as appropriate. Structure height shall not cause flood- ing or by -pass flow that would cause additional erosion. The structure should be inspected after every storm event. Any sediment should be removed and disposed of on the site. Any broken or damaged components should be re- placed. Check all materials for proper anchorage and se- cure as necessary. Type V - Manufactured Insert Inlet Protection The drainage area shall be limited to 1 acre at the drain in- let. All inserts will be installed and anchored in accordance with the manufacturers recommendations and design de- tails. The fabric portion of the structure will equal or exceed the performance standard for the silt fence fabric. The in- serts will be installed to preserve a minimum of 50 percent of the open, unobstructed design flow area of the storm drain inlet opening to maintain capacity for storm events.

Its purpose is to prevent off site storm run - on from entering a disturbed area and to prevent sediment laden storm runoff from leaving the construction site or disturbed area. Conditions Where Practice Applies Perimeter dike /swale is constructed to divert flows from entering a disturbed area, or along tops of slopes to prevent flows from eroding the slope, or along base of slopes to direct sediment laden flows to a trapping device. The perimeter dike /swale shall remain in place until the disturbed areas are permanently stabilized. Desij4n Criteria See Figure 3.14 on page 3.36 for details. The perimeter dike /swale shall not be constructed outside property lines or setbacks without obtaining legal ease- ments from affected adjacent property owners. A design is not required for perimeter dike /swale. The following crite- ria shall be used: Drainage area— Less than 2 acres (for drainage areas larg- er than 2 acres but less than 10 acres, see earth dike or construction ditch; for drainage areas larger than 10 acres, see standard and specifications for diversion). Height — 18 inches minimum from bottom of swale to top of dike evenly divided between dike height and swale depth. Bottom width of dike — 2 feet minimum. Width of swale — 2 feet minimum. Grade — Dependent upon topography, but shal I have positive drainage (sufficient grade to drain) to an ade- quate outlet. Maximum allowable grade not to exceed 8 percent. Stabilization — The disturbed area of the dike and swale shall be stabilized within 2 days of installation, in accord- ance with the standard and specifications for construction ditch (page 3.4). Outlet 1. Perimeter dike /swale shall have a stabilized outlet. 2. Diverted runoff from a protected or stabilized upland area shall outlet directly onto an undisturbed stabilized area. 3. Diverted runoff from a disturbed or exposed upland area shall be conveyed to a sediment trapping device such as a sediment trap, sediment basin, or to an area protected by any of these practices. 4. The on -site location may need to be adjusted to meet field conditions in order to utilize the most suitable out I et.

Straw bale dikes have an estimated design life of three (3) months. Condition 'Where Practice Applies The straw bale dike is used where: 1. No other practice is feasible. 2. There is no concentration of water in a channel or other drainageway above the barrier. 3. Erosion would occur in the form of sheet erosion. 4. Length of slope above the straw bale dike does not ex- ceed the following limits with the bale placed 10 feet from the toe of the slope: Constructed Slope Percent Slope Slope Length (ft.) 2:1 50 25 3:1 4:1 33 50 25 75 Where slope gradient changes through the drainage area, steepness refers to the steepest slope section con- tributing to the straw bale dike. The practice may also be used for a single family lot if the slope is less than 15 percent. The contributing drainage areas in this instance shall be less than one quarter of an acre per 100 feet of dike and the length of slope above the dike shall be less than 100 feet. Desi;,n Criteria The above table is adequate, in general, for a one -inch rain- fall event. Larger storms could cause failure of this prac- tice. Use of this practice in sensitive areas for longer than one month should be specifically designed to store expected runoff. All bales shall be placed on the contour with cut edge of bale adhering to the ground. See Figure 5.34 on page 5.64 for details.

NEW YORK STATE SOIL a WATER CONSERVATION COMMITTEE STRAW BALE DIKE November 2016 Page 5.64 New York State Standards and Specifica- tions For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR DUST CONTROL i - ,� --�. Definition & Scope The control of dust resulting from land- disturbing activities, to prevent surface and air movement of dust from disturbed soil surfaces that may cause off -site damage, health hazards, and traffic safety problems. Conditions Where Practice Applies On construction roads, access points, and other disturbed areas subject to surface dust movement and dust blowing where off -site damage may occur if dust is not controlled. Design Criteria Construction operations should be scheduled to minimize the amount of area disturbed at one time. Buffer areas of vegetation should be left where practical. Temporary or permanent stabilization measures shall be installed. No specific design criteria is given; see construction specifications below for common methods of dust control. Water quality must be considered when materials are selected for dust control. Where there is a potential for the material to wash off to a stream, ingredient information must be provided to the NYSDEC. No polymer application shall take place without written approval from the NYSDEC. Construction Specifications A. Non- driving Areas — These areas use products and materials applied or placed on soil surfaces to prevent airborne migration of soil particles. Vegetative Cover — For disturbed areas not subject to traffic, vegetation provides the most practical method of dust control (see Section 3). Mulch (including gravel mulch) — Mulch offers a fast effective means of controlling dust. This can also include rolled erosion control blankets. Spray adhesives — These are products generally composed of polymers in a liquid or solid form that are mixed with water to form an emulsion that is sprayed on the soil surface with typical hydroseeding equipment. The mixing ratios and application rates will be in accordance with the manufacturer's recommendations for the specific soils on the site. In no case should the application of these adhesives be made on wet soils or if there is a probability of precipitation within 48 hours of its proposed use. Material Safety Data Sheets will be provided to all applicators and others working with the material. B. Driving Areas — These areas utilize water, polymer emulsions, and barriers to prevent dust movement from the traffic surface into the air. Sprinkling — The site may be sprayed with water until the surface is wet. This is especially effective on haul roads and access route to provide short term limited dust control. Polymer Additives — These polymers are mixed with water and applied to the driving surface by a water truck with a gravity feed drip bar, spray bar or automated distributor truck. The mixing ratios and application rates will be in accordance with the manufacturer's recommendations. Incorporation of the emulsion into the soil will be done to the appropriate depth based on expected traffic. Compaction after incorporation will be by vibratory roller to a minimum of 95 %. The prepared surface shall be moist and no application of the polymer will be made if there is a probability of precipitation within 48 hours of its proposed use. Material Safety Data Sheets will be provided to all applicators working with the material. Barriers — Woven geo- textiles can be placed on the driving surface to effectively reduce dust throw and particle migration on haul roads. Stone can also be used for construction roads for effective dust control. Windbreak— A silt fence or similar barrier can control air currents at intervals equal to ten times the barrier height. Preserve existing wind barrier vegetation as much as practical. Maintenance Maintain dust control measures through dry weather periods until all disturbed areas are stabilized. New York State Standards and Specifications Page 2.25 November 2016 For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR SITE POLLUTION PREVENTION R '~ �4'.�..T Definition & Scope A collection of management practices intended to control non- sediment pollutants associated with construction activities to prevent the generation of pollutants due to improper handling, storage, and spills and prevent the movement of toxic substances from the site into surface waters. Conditions Where Practice Applies On all construction sites where the earth disturbance exceeds 5,000 square feet, and involves the use of fertilizers, pesticides, petroleum based chemicals, fuels and lubricants, as well as sealers, paints, cleared woody vegetation, garbage, and sanitary wastes. Design Criteria The variety of pollutants on a particular site and the severity of their impacts depend on factors such as the nature of the construction activity, the physical characteristics of the construction site, and the proximity of water bodies and conveyances to the pollutant source. pollutants and contamination of groundwater and surface waters. 5. Develop and implement a spill prevention and control plan. The plan should include NYSDEC's spill reporting and initial notification requirements. 6. Provide adequate disposal for solid waste including woody debris, stumps, and other construction waste and include these methods and directions in the construction details on the site construction drawings. Fill, woody debris, stumps and construction waste shall not be placed in regulated wetlands, streams or other surface waters. 7. Distribute or post informational material regarding proper handling, spill response, spill kit location, and emergency actions to be taken, to all construction personnel. 8. Refueling equipment shall be located at least 100 feet from all wetlands, streams and other surface waters. 1. All state and federal regulations shall be followed for -max l the storage, handling, application, usage, and disposal of pesticides, fertilizers, and petroleum products. 2. Vehicle and construction equipment staging and maintenance areas will be located away from all drainage ways with their parking areas graded so the runoff from these areas is collected, contained and treated prior to discharge from the site. 3. Provide sanitary facilities for on -site personnel. 4. Store, cover, and isolate construction materials including topsoil, and chemicals, to prevent runoff of New York State Standards and Specifications Page 2.29 For Erosion and Sediment Control November 2016 STANDARD AND SPECIFICATIONS FOR LANDGRADING Derinition & Scone Permanent reshaping of the existing land surface by grading in accordance with an engineering topographic plan and specification to provide for erosion control and vegetative establishment on disturbed, reshaped areas. Design Criteria The grading plan should be based upon the incorporation of building designs and street layouts that fit and utilize existing topography and desirable natural surrounding to avoid extreme grade modifications. Information submitted must provide sufficient topographic surveys and soil investigations to determine limitations that must be imposed on the grading operation related to slope stability, effect on adjacent properties and drainage patterns, measures for drainage and water removal, and vegetative treatment, etc. damage slopes or other graded areas; see standards and specifications for Grassed Waterway, Diversion, or Grade Stabilization Structure. 2. Cut and fill slopes that are to be stabilized with grasses shall not be steeper than 2:1. When slopes exceed 2:1, special design and stabilization consideration are required and shall be adequately shown on the plans. (Note: Where the slope is to be mowed, the slope should be no steeper than 3:1, although 4:1 is preferred because of safety factors related to mowing steep slopes.) 3. Reverse slope benches or diversion shall be provided whenever the vertical interval (height) of any 2:1 slope exceeds 20 feet; for 3:1 slope it shall be increased to 30 feet and for 4:1 to 40 feet. Benches shall be located to divide -the slope -face as equally aspossiblc and - shall - - convey the water to a stable outlet. Soils, seeps, rock outcrops, etc., shall also be taken into consideration when designing benches. A. Benches shall be a minimum of six feet wide to provide for ease of maintenance. Many municipalities and counties have regulations and design procedures already established for land grading and 4. cut and fill slopes. Where these requirements exist, they shall be followed. The plan must show existing and proposed contours of the area(s) to be graded. The plan shall also include practices for erosion control, slope stabilization, safe disposal of runoff water and drainage, such as waterways, lined ditches, reverse slope benches (include grade and cross section), grade stabilization structures, retaining walls, and surface and subsurface drains. The plan shall also include phasing of these practices. The following shall be incorporated into the plan: 1. Provisions shall be made to safely convey surface runoff to storm drains, protected outlets, or to stable water courses to ensure that surface runoff will not B. Benches shall be designed with a reverse slope of 6:1 or flatter to the toe of the upper slope and with a minimum of one foot in depth. Bench gradient to the outlet shall be between 2 percent and 3 percent, unless accompanied by appropriate design and computations. C. The flow length within a bench shall not exceed 800 feet unless accompanied by appropriate design and computations; see Standard and Specifications for Diversion on page 3.9 Surface water shall be diverted from the face of all cut and /or fill slopes by the use of diversions, ditches and swales or conveyed downslope by the use of a designed structure, except where: A. The face of the slope is or shall be stabilized and the face of all graded slopes shall be protected from surface runoff until they are stabilized. B. The face of the slope shall not be subject to any concentrated flows of surface water such as from natural drainage ways, graded ditches, downspouts, etc. C. The face of the slope will be protected by anchored stabilization matting, sod, gravel, riprap, or other stabilization method. November 2016 Page 4.24 New York State Standards and Specifications For Erosion and Sediment Control a Cut slopes occurring in ripable rock shall be serrated as shown in Figure 4.9 on page 4.26. The serrations shall be made with conventional equipment as the excavation is made. Each step or serration shall be constructed on the contour and will have steps cut at nominal two -foot intervals with nominal three -foot horizontal shelves. These steps will vary depending on the slope ratio or the cut slope. The nominal slope line is 1 '' /z: 1. These steps will weather and act to hold moisture, lime, fertilizer, and seed thus producing a much quicker and longer -lived vegetative cover and better slope stabilization. Overland flow shall be diverted from the top of all serrated cut slopes and carried to a suitable outlet. 6. Subsurface drainage shall be provided where necessary to intercept seepage that would otherwise adversely affect slope stability or create excessively wet site conditions. 7. Slopes shall not be created so close to property lines as to endanger adjoining properties without adequately protecting such properties against sedimentation, erosion, slippage, settlement, subsidence, or other related damages. 8. Fill material shall be free of brush, rubbish, rocks, logs, stumps, building debris, and other objectionable material. It should be free of stones over two (2) inches in diameter where compacted by hand or mechanical tampers or over eight (8) inches in diameter where compacted by rollers or other equipment. Frozen material shall not be placed in the fill nor shall the fill material be placed on a frozen foundation. 9. Stockpiles, borrow areas, and spoil shall be shown on the plans and shall be subject to the provisions of this Standard and Specifications. 10. All disturbed areas shall be stabilized structurally or vegetatively in compliance with the Permanent Construction Area Planting Standard on page 4.42. Construction Specifications See Figures 4.9 and 4.10 for details. i . All graded or disturbed areas, including slopes, shall be protected during clearing and construction in accordance with the erosion and sediment control plan until they are adequately stabilized. 2. All erosion and sediment control practices and measures shall be constructed, applied and maintained in accordance with the erosion and sediment control plan and these standards. 3. Topsoil required for the establishment of vegetation shall be stockpiled in amount necessary to complete finished grading of all exposed areas. 4. Areas to be filled shall be cleared, grubbed, and stripped of topsoil to remove trees, vegetation, roots, or other objectionable material. 5. Areas that are to be topsoiled shall be scarified to a minimum depth of four inches prior to placement of topsoil. 6. All fills shall be compacted as required to reduce erosion, slippage, settlement, subsidence, or other related problems. Fill intended to support buildings, structures, and conduits, etc., shall be compacted in accordance with local requirements or codes. 7. All fill shall be placed and compacted in layers not to exceed 9 inches in thickness. 8. Except for approved landfills or nonstructural fills, fill material shall be free of frozen particles, brush, roots, sod, or other foreign objectionable materials that would interfere with, or prevent, construction of satisfactory tills. 9. Frozen material or soft, mucky or highly compressible materials shall not be incorporated into fill slopes or structural fills. 10. Fill shall not be placed on saturated or frozen surfaces. 11. All benches shall be kept free of sediment during all phases of development. 12. Seeps or springs encountered during construction shall be handled in accordance with the Standard and Specification for Subsurface Drain on page 3.48 or other approved methods. 13.

Conditions Where Practice Applies At all locations where a vigorous growth of vegetation is desired and the soil pH is less than 7.0 or neutral. Design Criteria Liming material sold in New York varies considerably in several ways. The mineral content (calcium and magnesium) of the limestone may be high or low and, the fineness or particle sizes vary between suppliers. Two types of limestone are sold. The most common is limestone high in calcium. Dolomitic limestone contains magnesium (Mg) and calcium (Ca). Limestone sold in NY varies from 0 to 20% Mg while the calcium content of lime varies from 14.7% to 51.5 %. Particle size determines how rapidly the calcium and magnesium will react with the acid in the soil. The finer the particle sizes, the quicker the reaction. When obtaining agricultural limestone, one should state on the specification that the amount should be adjusted to 100% effective neutralizing value (ENV). This is the way to compare materials as it adjusts for the reactive Ca and Mg and the particle size. The ENV is stated as the ratio needed to convert a limestone recommendation to 100% ENV. Thus, if the recommendation is 4 tons /acre of 100% ENV lime and the lime being used had an 80% ENV (1/ ENV = 1.25), 4 times 1.25 or 5 tons /acre would be required. The amount of limestone needed can be estimated by using the following table. A soil test is the only way to determine the soil pH. This table is very general, but it is useful for planning.

New York State Standards and Specifications Page 4.29 November 2016 For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR SOIL RESTORATION _ _ R r `'+WET A t� ' •- Definition & Scone The decompaction of areas of a development site or construction project where soils have been disturbed to recover the original properties and porosity of the soil; thus providing a sustainable growth medium for vegetation, reduction of runoff and filtering of pollutants from stormwater runoff. Conditions Where Practice Applies Soil restoration is to be applied to areas whose heavy construction traffic is done and final stabilization is to begin. This is generally applied in the cleanup, site restoration, and landscaping phase of construction followed by the permanent establishment of an appropriate ground cover to maintain the soil structure. Soil restoration measures should be applied over and adjacent to any runoff reduction practices to achieve design performance. tilt Design Criteria 1. Soil restoration areas will be designated on the plan views of areas to be disturbed. 2. Soil restoration will be completed in accordance with Table 4.6 on page 4.53. SItecilicatiort for Full Soil Restoration During periods of relatively low to moderate subsoil moisture, the disturbed subsoils are returned to rough grade and the following Soil Restoration steps applied: Apply 3 inches of compost over subsoil. The compost shall be well decomposed (matured at least 3 months), weed -free, organic matter. It shall be aerobically composted, possess no objectionable odors, and contain less than 1%, by dry weight, of man -made foreign matter. The physical parameters of the compost shall meet the standards listed in Table 5.2 - Compost Standards Table, except for "Particle Size" 100% will pass the 1/2" sieve. Note: All biosolids compost produced in New York State (or approved for importation) must meet NYS DEC's 6 NYCRR Part 360 (Solid Waste Management Facilities) requirements. The Part 360 requirements are equal to or more stringent than 40 CFR Part 503 which ensure safe standards for pathogen reduction and heavy metals content. 2. Till compost into subsoil to a depth of at least 12 inches using a cat - mounted ripper, tractor mounted disc, or tiller, to mix and circulate air and compost into the subsoil. 3. Rock -pick until uplifted stone /rock materials of four inches and larger size are cleaned off the site. 4. Apply topsoil to a depth of 6 inches. 5. Vegetate as required by the seeding plan. Use appropriate ground cover with deep roots to maintain the soil structure. 6. Topsoil may be manufactured as a mixture or a mineral component and organic material such as compost. November 2016 Page 4.52 New York State Standards and Specifications For Erosion and Sediment Control At the end of the project an inspector should be able to push a 3/8" metal bar 12 inches into the soil just with body weight. This should not be performed within the drip line of any existing trees or over utility installations that are within 24 inches of the surface. Maintenance Keep the site free of vehicular and foot traffic or other weight loads. Consider pedestrian footpaths.

Conditions Where Practice Applies Topsoil is applied to subsoils that are droughty (.low available moisture for plants), stony, slowly permeable, salty or extremely acid. It is also used to backfill around shrub and tree transplants. This standard does not apply to wetland soils. Design Criteria 1. Preserve existing topsoil in place where possible, thereby reducing the need for added topsoil. Conserve by stockpiling topsoil and friable fine textured subsoils that must be stripped from the excavated site and applied after final grading where vegetation will be established. Topsoil stockpiles must be stabilized. Stockpile surfaces can be stabilized by vegetation, geotextile or plastic covers. This can be aided by orientating the stockpile lengthwise into prevailing winds. 3. Refer to USDA Natural Resource Conservation Service soil surveys or soil interpretation record sheets for further soil texture information for selecting appropriate design topsoil depths. Site Preparation 1. As needed, install erosion and sediment control practices such as diversions, channels, sediment traps, and stabilizing measures, or maintain if already installed. 2. Complete rough grading and final grade, allowing for depth of topsoil to be added. 3. Scarify all compact, slowly permeable, medium and fine textured subsoil areas. Scarify at approximately right angles to the slope direction in soil areas that are steeper than 5 percent. Areas that have been overly compacted shall be decompacted in accordance with the Soil Restoration Standard. 4. Remove refuse, woody plant parts, stories over 3 inches in diameter, and other litter. Topsoil Materials 1. Topsoil shall have at least 6 percent by weight of fine textured stable organic material, and no greater than 20 percent. Muck soil shall not be considered topsoil. 2. Topsoil shall have not less than 20 percent fine textured material (passing the NO. 200 sieve) and not more than 15 percent clay. 3. Topsoil treated with soil sterilants or herbicides shall be so identified to the purchaser. 4. Topsoil shall be relatively free of stones over 1 1/2 inches in diameter, trash, noxious weeds such as nut sedge and quackgrass, and will have less than 10 percent gravel. 5. Topsoil containing soluble salts greater than 500 parts per million shall not be used. 6. Topsoil may be manufactured as a mixture of a mineral component and organic material such as compost. Application and Grading 1. Topsoil shall be distributed to a uniform depth over the area. It shall not be placed when it is partly frozen, muddy, or on frozen slopes or over ice, snow, or standing water puddles. 2. Topsoil placed and graded on slopes steeper than 5 percent shall be promptly fertilized, seeded, mulched, and stabilized by "tracking" with suitable equipment. 3. Apply topsoil in the amounts shown in Table 4.7 below: New York State Standards and Specifications Page 4.59 November 2016 For Erosion and Sediment Control Table 4.7 - Topsoil Application Depth Site Conditions Intended Use Minimum Topsoil Depth 1.

November 2016 Page 4.60 New York State Standards and Specifications For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR MULCHING Definition and Scoue Applying coarse plant residue or chips, or other suitable materials, to cover the soil surface to provide initial erosion control while a seeding or shrub planting is establishing. Mulch will conserve moisture and modify the surface soil temperature and reduce fluctuation of both. Mulch will prevent soil surface crusting and aid in weed control. Mulch can also be used alone for temporary stabilization in non - growing months. Use of stone as a mulch could be more permanent and should not be limited to non - growing months. Conditions Where Practice Applies On soils subject to erosion and on new seedings and shrub plantings. Mulch is useful on soils with low infiltration rates by retarding runoff. Criteria Site preparation prior to mulching requires the installation of necessary erosion control or water management practices and drainage systems. Slope, grade and smooth the site to fit needs of selected mulch products. Remove all undesirable stones and other debris to meet the needs of the anticipated land use and maintenance required. Apply mulch after soil amendments and planting is accomplished or simultaneously if hydroseeding is used. Select appropriate mulch material and application rate or material needs. Hay mulch shall not be used in wetlands or in areas of permanent seeding. Clean straw mulch is preferred alternative in wetland application. Determine local availability. Select appropriate mulch anchoring material. NOTE: The best combination for grass /legume establishment is straw (cereal grain) mulch applied at 2 ton/ acre (90 lbs. /l000sq.ft.) and anchored with wood fiber mulch (hydromulch) at 500 — 750 lbs. /acre (1 l — 17 lbs. /1000 sq. ft.). The wood fiber mulch must be applied through a hydroseeder immediately after mulching.

New York State Standards and Specifications Page 4.41 November 2016 For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR PERMANENT CONSTRUCTION AREA PLANTING Definition & Scone Establishing permanent grasses with other forbs and /or shrubs to provide a minimum 80% perennial vegetative cover on areas disturbed by construction and critical areas to reduce erosion and sediment transport. Critical areas may include but are not limited to steep excavated cut or fill slopes as well as eroding or denuded natural slopes and areas subject to erosion. Conditions Where Practice Applies This practice applies to all disturbed areas void of, or having insufficient, cover to prevent erosion and sediment transport. See additional standards for special situations such as sand dunes and sand and gravel pits. Criteria All water control measures will be installed as needed prior to final grading and seedbed preparation. Any severely compacted sections will require chiseling or disking to provide an adequate rooting zone, to a minimum depth of 12 ", see Soil Restoration Standard. The seedbed must be prepared to allow good soil to seed contact, with the soil not too soft and not too compact. Adequate soil moisture must be present to accomplish this. If surface is powder dry or sticky wet, postpone operations until moisture changes to a favorable condition. If seeding is accomplished within 24 hours of final grading, additional scarification is generally not needed, especially on ditch or stream banks. Remove all stones and other debris from the surface that are greater than 4 inches, or that will interfere with future mowing or maintenance. Soil amendments should be incorporated into the upper 2 inches of soil when feasible. The soil should be tested to determine the amounts of amendments needed. Apply ground agricultural limestone to attain a pH of 6.0 in the upper 2 inches of soil. If soil must be fertilized before results of a soil test can be obtained to determine fertilizer needs, apply commercial fertilizer at 600 lbs. per acre of 5 -5 -10 or equivalent. If manure is used, apply a quantity to meet the nutrients of the above fertilizer. This requires an appropriate manure analysis prior to applying to the site. Do not use manure on sites to be planted with birdsfoot trefoil or in the path of concentrated water flow. Seed mixtures may vary depending on location within the state and time of seeding. Generally, warm season grasses should only be seeded during early spring, April to May. These grasses are primarily used for vegetating excessively drained sands and gravels. See Standard and Specification for Sand and Gravel Mine Reclamation. Other grasses may be seeded any time of the year when the soil is not frozen and is workable. When legumes such as birdsfoot trefoil are included, spring seeding is preferred. See Table 4.4, "Permanent Construction Area Planting Mixture Recommendations" for additional seed mixtures. General Seed Mix: lbs./ Ibs /1000 Variety acre sq. ft. Red Clover' OR Acclaim, Rally, 8' 0.20 Red Head II, Renegade Common white clover' Common 8 0.20 PLUS Creeping Red Fescue Common 20 0.45 PLUS Smooth Bromegrass Common 2 0.05 OR Ryegrass (perennial) Pennfine /Linn 5 0.10 add inoculant immediately prior to seeding 2 Mix 4 lbs each of Empire and Pardee OR 4 lbs of Birdsfoot and 4 lbs white clover per acre. All seeding rates are given for Pure Live Seed (PLS) Pure Live Seed, or (PLS) refers to the amount of live seed in a lot of bulk seed. Information on the seed bag label includes the type of seed, supplier, test date, source of seed, purity, and germination. Purity is the percentage of pure seed. Germination is the percentage of pure seed that will produce normal plants when planted under favorable conditions. November 2016 Page 4.42 New York State Standards and Specifications For Erosion and Sediment Control To compute Pure Live Seed multiply the "germination percent" times the "purity" and divide that by 100 to get Pure Live Seed. PunLiveSoM0W)= %GCrmil MdM x% PUrifty 100 For example, the PLS for a lot of Kentucky Blue grass with 75% purity and 96% germination would be calculated as follows: (96) x (75) = 72% Pure Live Seed 100 For l Olbs of PLS from this lot = 10 =13.9 ft 0.72 Therefore, 13.9 lbs of seed is the actual weight needed to meet 1 Olbs PSL from this specific seed lot. Time of Seeding: The optimum timing for the general seed mixture is early spring. Permanent seedings may be made any time of year if properly mulched and adequate moisture is provided. Late June through early August is not a good time to seed, but may facilitate covering the land without additional disturbance if construction is completed. Portions of the seeding may fail due to drought and heat. These areas may need reseeding in late summer /fall or the following spring. Method of seeding: Broadcasting, drilling, cultipack type seeding, or hydroseeding are acceptable methods. Proper soil to seed contact is key to successful seedings. Mulching: Mulching is essential to obtain a uniform stand of seeded plants. Optimum benefits of mulching new seedings are obtained with the use of small grain straw applied at a rate of 2 tons per acre, and anchored with a netting or tackifier. See the Standard and Specifications for Mulching for choices and requirements. Irrigation: Watering may be essential to establish a new seeding when a drought condition occurs shortly after a new seeding emerges. Irrigation is a specialized practice and care must be taken not to exceed the application rate for the soil or subsoil. When disconnecting irrigation pipe, be sure pipes are drained in a safe manor, not creating an erosion concern. 801,,6 Perennial Vegetative Cover 50% Perennial Vegetative Cover New York State Standards and Specifications Page 4.43 November 2016 For Erosion and Sediment Control Table 4.4 Permanent Construction Area Planting Mixture Recommendations Seed Mixture Variety Rate in lbs. /acre (PLS) Rate in lbs./ 1, 000 ft Mix #1 Creeping red fescue Ensylva, Pennlawn, Boreal 10 .25 Perennial ryegrass Pennfne, Linn 10 .25 *'Phis mix is used extensively for shaded areas.

Time of Planting Fall planting is preferred. Seed after August 15. In the spring, plant until May 15. If seeding is done between May 15 and August 15, irrigation may be necessary to ensure a successful seeding. 2. Site Preparation A. Install needed water and erosion control measures and bring area to be seeded to desired grades. A minimum of 4 in. topsoil is required. B. Prepare seedbed by loosening soil to a depth of 4 -6 inches and decompacting required areas per Soil Restoration Standard. C. See Standard and Specification of Topsoiling. D. Lime to a pH of 6.5. See Lime Application Standard. E. Fertilize as per soil test or, if soil must be fertilized before results of a soil test can be obtained to determine fertilizer needs, apply commercial fertilizer at 850 pounds of 5 -5 -10 or equivalent per acre (20 lbs /1,000 sq. ft.). See Fertilizer Application Standard. F. Incorporate lime and fertilizer in top 2 -4 inches of topsoil. G. Smooth. Remove sticks, foreign matter, and stones over 1 inch in diameter, from the surface. Firm the seedbed. 3. Planting Use a cultipacker type seeder if possible. Seed to a depth of 1/8 to 1/4 inch. If seed is to be broadcast, cultipack or roll after seeding. If hyroseeded, lime and fertilizer may be applied through the seeder, and rolling is not practical. 4. Mulching Mulch al I seedings in accordance with Standard and Specifications for Mulching. Small grain straw is the best material. 5. Seed Mixtures Select seed mixture for site conditions and intended use from Table 4.5. 6. Contact Cornell Cooperative Extension Turf Specialist for suitable varieties. Turf -type tall fescues have replaced the old KY31 tall fescues. New varieties have finer leaves and are the most resistant grass to foot traffic. Do not mix it with fine textured grasses such as bluegrass and red fescue. Common ryegrass and redtop, which are relatively short lived species, provide quick green cover. Improved lawn cultivars of perennial ryegrass provide excellent quality turf, but continue to lack winter hardiness. Common white clover can be added to mixtures at the rate of 1 -2 lbs /acre to help maintain green color during the dry summer period; however, they will not withstand heavy traffic. Avoid using around swimming areas as flowers attract bees which can be easily stepped on.
