The applicant has stated that the building is proposed to be 36 feet high at the apex of  the pitched roof, with a cupola protruding to 42.8 feet above the apex of the roof.   Rooftop apparatus taller than normal height limitations for the district may be  approved by the Board as a conditional use.  The applicant is requesting conditional  use approval for the proposed cupola.  Staff has included conditional use criteria  below.    2. Staff recommends the Board clarify whether the applicant is are asking for conditional use approval  for both proposed buildings, and if not, which they are requesting the approval for.    6.04 Industrial‐Open Space District (IO)  The purpose of the Industrial‐Open Space District is as follows.    To provide suitable locations for high‐quality, large‐lot office, light industrial and research  uses in areas of the City with access to major arterial routes and Burlington International  Airport. The IO District regulations and standards are intended to allow high‐quality planned  developments that preserve the generally open character of the district, minimize impacts on  natural resources and water quality, and enhance the visual quality of approaches to the City  while providing suitable locations for employment and business growth. The location and  architectural design of buildings in a manner that preserves these qualities is strongly  encouraged.     Staff encourages the Board to consider this purpose in reviewing this project.    6.05 Supplemental Standards for Industrial and Airport Districts  A. Site plan or PUD review required.  The application is for an existing PUD.  Staff considers this criterion met.    B. Multiple Structures and uses permitted.  If the Board determines there is sufficient frontage, lot size, and lot depth, multiple structures,  multiple uses within structures, and multiple uses on a site may be allowed.  Staff considers  this criterion met.      C. [Reserved]    D. Buffer Strip.  Properties are required to provide a screen or buffer along the line abutting a  residential district.    No changes are proposed to the side of the property which abuts the residential district.  Staff  considers this criterion met.    SUBDIVISION STANDARDS    (1) Sufficient water supply and wastewater disposal capacity is available to meet the needs of the  project in conformance with applicable State and City requirements, as evidenced by a City water  allocation, City wastewater allocation, and/or Vermont Water and Wastewater Permit from the  Department of Environmental Conservation.    #SD‐20‐02  Staff Comments 4 4 of 15  The applicant has stated in their application that they have received state wastewater permit for the  water  and  sewer  improvements  and  allocations  for  the  two  buildings,  but  has  not  submitted  preliminary water or wastewater allocations to the City.  The PUD received preliminary wastewater  allocation in 2007 for a different use.      3. Staff recommends the Board require the applicant to apply for preliminary water and wastewater  allocation prior to the continued hearing.    (2) Sufficient grading and erosion controls will be utilized during construction and after construction to  prevent soil erosion and runoff from creating unhealthy or dangerous conditions on the subject  property and adjacent properties. In making this finding, the DRB may rely on evidence that the  project  will  be  covered  under  the  General  Permit  for  Construction  issued  by  the  Vermont  Department of Environmental Conservation.    The applicant has submitted an erosion prevention and sediment control plan.  Staff notes the project  disturbs greater than 1 acre and will therefore be required to obtain a construction permit from DEC.      4. Staff recommends the Board require the applicant to amend their plans to reflect a maximum of 24  hours between final grading and placement of final stabilization measures, as required in Article 16.    (3) The project incorporates access, circulation and traffic management strategies sufficient to prevent  unreasonable congestion of adjacent roads. In making this finding the DRB may rely on the findings  of a traffic study submitted by the applicant, and the findings of any technical review by City staff  or consultants.  Sections 13.01F, 15.12D(4) and 15.12F(4) support this standard:    13.01F  Access Management Requirements. It is the intent of the City to minimize traffic and  pedestrian conflicts caused by vehicular driveways on public roadways by reducing the number  of required driveways and by minimizing the number of vehicles utilizing such driveways off  public roadways. All applicants must make an effort to reduce these impacts. All commercial  lots (retail, restaurant, office, service uses, excluding residential, agricultural and industrial  uses) located adjacent to other commercial lots must provide a driveway connection to any  adjacent commercial lot. If the adjacent property owner does not want to provide for that  connection, the applicant must provide an easement to do so in the future when circumstances  may change. This driveway connection or easement should be located where the vehicular and  pedestrian circulation is most feasible.    15.12D(4)  Connections to adjacent parcels.   (a)   If the DRB finds that a roadway or recreation path extension or connection to an  adjacent  property  may  or  could  occur  in  the  future,  whether  through  City  action  or  development of an adjacent parcel, the DRB shall require the applicant to construct the  roadway to the property line or contribute the cost of completing the roadway connection.     15.12F(4)  The location and design of project access shall make provisions for improved  access management and traffic safety. Specifically, the design of PUD and subdivision access  points shall:  (a)  Maximize the use of secondary streets for access and circulation  (b)  Align access points with existing intersections and/or curb cuts  (c)  Consolidate existing curb cuts within the PUD property  #SD‐20‐02  Staff Comments 5 5 of 15  (d)  Provide for safe access to abutting properties  (e)  Make provisions for safe access, with provisions for appropriate sight distances and  accommodations for high‐accident locations  (f)   Provide deceleration, acceleration and/or turn stacking lanes as appropriate to meet  the standards in (1) above.   (g)  Provide adequate curb radii to accommodate the anticipated speeds and types of  vehicles.    This property is situated east of VT 116, directly across from the commercial portion of Rye  Meadows, and south and west of Meadowland Drive.  It is in the industrial open space zoning  district.  The property is the beneficiary of an access easement which allows it to share a single  access onto VT 116 with the property to the north.  The adjoining property to the east has an  easement which extends to the property line, providing for a shared driveway for the existing Keller  Williams building and for a future building located south of the easement.    LDR 15.12D(4) requires  connections be made to adjacent properties at the time of approval for the property.      At sketch, the Board discussed this requirement at length.  The applicant expressed their reluctance  to provide a connection to the Keller Williams property to the east as they did not feel the abutting  property owner to the north, with whom they share an access, would support such an access.  Staff  has reviewed the shared access agreement between the subject property and the property to the  north, which the applicant has included in the application package for the Board.  The agreement  states that the applicant shall, at the time that a roadway connection to the property to the east is  required, request and aggressively promote that the easement should be for emergency access only  and be controlled by a gate or other suitable means, in exchange for the neighbor to the north  waiving their right to appeal the project.  Staff notes this agreement is not with the City; it is purely  between the applicant and their neighbor to the north.  Staff further notes that the applicant has  partially complied with the request of the Board at sketch and has extended the driveway to the  property line to the east, but has blocked that access with a gate and indicated it is for emergency  access only.      5. Staff recommends the Board review the above‐excerpted provisions of the LDRs.  Staff considers the  LDRs require access between properties for the purpose of circulation and safety, and restricting such  access to emergencies only does not comply the requirements of the LDRs.     As discussed at sketch, the applicant has enhanced the traffic calming measures with a speed table,  a sinuous alignment, and a number of shade trees along the driveway, which provide visual cues  that the driveway is a cross‐lot connection and not a principal access to Meadowland Business Park.   Other provisions of the provided shared access agreement indicate that the neighbor’s goals are no  greater than 85 PM peak hour vehicle trips and no vehicles in excess of 24‐feet.  Staff considers that,  if the Board is inclined to take the neighbors goals into consideration in determining whether to  allow a gate, the applicant’s proposed trip generation is 42 vehicle trips per peak hour and they may  install signage limiting to vehicles those less than 24‐feet.      6. Staff recommends the Board require the applicant to remove the proposed gate from the plan.  At  such time as the Keller Williams property to the east is developed, the applicant has the option to  renew their request to install a gate.    Staff otherwise supports the applicant’s proposed driveway configuration as it minimizes the  number of access points from the driveway to the proposed parking lot, and improve the  #SD‐20‐02  Staff Comments 6 6 of 15  intersections to more clearly delineate primary and secondary drives.  (4) The project’s design respects and will provide suitable protection to wetlands, streams, wildlife  habitat as identified in the Open Space Strategy, and any unique natural features on the site. In  making this finding the DRB shall utilize the provisions of Article 12 of these Regulations related to  wetlands and stream buffers, and may seek comment from the Natural Resources Committee with  respect to the project’s impact on natural resources.    There do not appear to be wetlands proposed to be impacted by the development.  Stormwater  impacts are discussed under criterion #11 below.    (5) The project is designed to be visually compatible with the planned development patterns in the area,  as specified in the Comprehensive Plan and the purpose of the zoning district(s) in which it is located.    The  planned  development  pattern  in  this  area  is  medium  to  higher  intensity  principally  non‐residential.  The purpose of the industrial open space district is stated above.  Staff considers this  criterion met.    (6) Open space areas on the site have been located in such a way as to maximize opportunities for  creating contiguous open spaces between adjoining parcels and/or stream buffer areas.     The applicant is proposing to configure the lot to create a central open space.  This is a major feature  of the proposed layout and was the subject of discussion at sketch plan.  Since there are no significant  natural  features  on  the  site,  Staff  considers  this  an  appropriate  approach  to  this  criterion  and  considers this criterion met.    (7) The layout of a subdivision or PUD has been reviewed by the Fire Chief or his designee to insure that  adequate fire protection can be provided, with the standards for approval including, but not be  limited to, minimum distance between structures, street width, vehicular access from two directions  where possible, looping of water lines, water flow and pressure, and number and location of  hydrants. All aspects of fire protection systems shall be designed and installed in accordance with  applicable codes in all areas served by municipal water.    The Fire Inspector reviewed the plans on January 28, 2020 and requests demonstration that a WB‐40  1990 template can navigate the site, and that the hydrant be moved towards the center of the island.      7. Staff recommends the Board require the applicant to demonstrate compliance with the turning request  prior to closing the hearing, and considers the hydrant request can be a condition of approval.      (8) Roads, recreation paths, stormwater facilities, sidewalks, landscaping, utility lines and lighting have  been designed in a manner that is compatible with the extension of such services and infrastructure  to adjacent properties.    Extension to adjacent properties is discussed under PUD criterion 3 above.    The Director of Public Works reviewed the plans on January 28, 2020 and offers the following  comment.    #SD‐20‐02  Staff Comments 7 7 of 15  Only comment here is a question as to why the proposed bikepath 1) isn’t entirely within the  highway ROW and 2) why it jogs to the west as it heads north.     Staff notes the path is located within the existing recreation path easement at the south end of the  site and then jogs into the ROW to the north once it passes existing trees that at sketch the applicant  described as warranting saving.  The Hinesburg Road ROW is planned in the future to be expanded  and the northern section of the path would be fully within that ROW at the time the ROW is expanded.      8. Staff recommends the Board discuss whether the applicant should locate the path in the existing  recreation path easement, or shift it towards the existing ROW and into the proposed ROW when  possible as they have done.      The South Burlington Water Department Superintendent reviewed the plans on January 30, 2020 and  offers the following comments.    Sheet C2.2: At the end of the proposed 8” C900 water line, near Sta 1+10, the proposed tee  should have two valves connected to it.  Add a short stub and precast thrust block at the end of  the line if that line may ever be extended.  Both valves may be shown on the plans but are not  identified.  It this line will never be extended then two 45‐degree bends should be installed  instead of the tee.    Sheet C2.2: The hydrant tee shall include a valve for the hydrant lead and a valve on the  downstream line that will supply building B and C, both connected to the tee.    General: Add a note stating:  All water lines and appurtenances shall be installed in accordance  with the Champlain Water District Specifications and Detail for the Installation of Water Lines  and Appurtenances, current edition, henceforth the CWD Specifications.  General:  C‐900 PVC pipe is approved for this project.  All fittings, valves, bends, and the fire  hydrant shall be installed with VBio poly wrap.  Tracer wire shall be installed per the CWD  Specifications.    9. Staff recommends the Board require the applicant to comply with the comments of the SBWD as  conditions of approval.    (9) Roads, utilities, sidewalks, recreation paths, and lighting are designed in a manner that is consistent  with City utility and roadway plans and maintenance standards, absent a specific agreement with  the applicant related to maintenance that has been approved by the City Council.    Compliance with stormwater standards is discussed under PUD criterion 11 below.  Staff considers  the remainder of this criterion met.    (10) The project is consistent with the goals and objectives of the Comprehensive Plan for the  affected district(s).    The Goals of the comprehensive plan follow.  1. Affordable & community Strong.  Creating a robust sense of place and opportunity for our  residents and visitors.  #SD‐20‐02  Staff Comments 8 8 of 15  2.

Opportunity Oriented. Being a supportive and engaged member of the larger regional and  statewide community.  The project lies within the Southeast Quadrant Land Use Planning Area of the city.  Southeast  Quadrant objectives in the Comprehensive Plan are:  60. Give priority to the conservation of contiguous and interconnected open space areas within this  quadrant outside of those areas [districts, zones] specifically designated for development.  61. Maintain opportunities for traditional and emerging forms of agriculture that complement and  help sustain a growing city, and maintain the productivity of South Burlington’s remaining  agricultural lands.  62. Enhance Dorset Street as the SEQ’s “main street” with traffic calming techniques, streetscape  improvements, safe interconnected pedestrian pathways and crossings, and a roadway profile  suited to its intended local traffic function.  Staff considers this project, located in a development district and designed with high quality aesthetics  and open spaces, consistent with the of the comprehensive plan.    (11) The  project’s  design  incorporates  strategies  that  minimize  site disturbance and integrate  structures, landscaping, natural hydrologic functions, and other techniques to generate less runoff  from developed land and to infiltrate rainfall into underlying soils and groundwater as close as  possible to where it hits the ground. For Transect Zone subdivisions, this standard shall apply only  to the location of natural resources identified in Article XII of these Regulations.    The Stormwater Section provided comments on the plans on February 3, 2020.      The Stormwater Section (City) has reviewed the “Subdivision of Lot 1A – CEA Campus Planned Unit  Development” sketch plan prepared by Civil Engineering Associates (CEA), dated Dec. 20, 2019 and  last updated on Jan. 10, 2020. We would like to provide the following comments:  1. The proposed project is located in the Potash Brook watershed which is now classified as a  warm water stream. Additionally, precipitation for Water Quality Volume is now measured as  1” per 24‐hour instead of 0.9”. Has  the applicant discussed these  changes  with  VT  DEC  Stormwater team to determine the potential impacts to the modeling?   2. The plans indicate that stormwater from lot 1A will be conveyed to an existing dry basin (Pond  1) located on Lot 1 and then on to Pond 2. The applicant is proposing to use Pond 2 and Grass  Channels to meet WQv standards. Have modifications been made to Pond 2 so that it meets  the 2002 VSMM design standards? If modifications have not occurred and the existing BMP  does not meet the 2002 standards, the design must forgo consideration of existing STP for  meeting WQTS, and utilize standards in the 2017 VSMM (see Section 2.2.4.1(d) of the VSMM).  Further, Dry Detention Ponds are not suitable for meeting water quality or recharge criteria  as  standalone  best  management  practices  and  grass  channels  are not  identified  as  an  acceptable  practice  for  meeting WQTS in the 2017 VSMM. It is recommended  that  the  applicant address these concerns with the VT DEC Stormwater team.  #SD‐20‐02  Staff Comments 9 9 of 15  3.

Small receptacles intended for use by households or the public (ie, non‐dumpster, non‐large drum)  shall not be required to be fenced or screened.    The applicant has a provided a detail for dumpster screening and has shown the proposed location of  the dumpster on the plans. Staff considers this criterion met.    D.  Landscaping and Screening Requirements. See Article 13, Section 13.06 Landscaping,  Screening, and Street Trees.    The minimum required landscape value for the Project, based on an estimated building construction  cost of $2.8 million is $30,500.  The applicant has proposed $24,800 in trees and $6,000 in three  benches proposed to be located in the interior mini park.  The Board may allow credit for site  improvements other than landscaping if the Board finds the other standards of 13.06 not diminished,  including that the site be well landscaped.      12. Staff recommends the Board discuss whether they accept the applicant’s request to provide  benches in lieu of trees and shrubs for $5,700 of their required minimum landscape value.    The City Arborist reviewed the landscaping plan on January 28, 2020 and did not have any problems  with the proposed plantings but requested tree planting details and specifications be included.    13. Staff recommends the Board require the applicant to provide tree planting details and  specifications for review of the City Arborist prior to the continued hearing.    Several additional landscaping standards apply to this property, as follows.    13.06B Landscaping of Parking Areas  All off‐street parking areas subject to review by the Development Review Board shall be  curbed and landscaped with appropriate trees, shrubs and other plans including ground covers  as approved by the Development Review Board.   #SD‐20‐02  Staff Comments 12 12 of 15    (1) All off‐street parking areas shall be landscaped around the perimeter of the lot with  trees, shrubs and other plants. Perimeter planting shall be set back from the curb  sufficiently to allow for snow storage. The purpose of perimeter planting shall be to  mitigate the view of the parking lot from the public way and from adjacent uses and  properties, and to provide shade and canopy for the parking lot. In some situations  it may be necessary both for surveillance purposes and for the perception of safety  to install the size and type of plants that leave visual access between the parking lot  to the public way or other pedestrian areas.    Though  perimeter screening is limited, based on topography  and setbacks, Staff  considers this criterion adequately met.    (2) In all parking areas containing twenty‐eight (28) or more contiguous parking spaces  and/or in parking lots with more than a single circulation lane, at least ten percent  (10%) of the interior of the parking lot shall be landscaped islands planted with  trees,  shrubs  and  other  plants.  Such  requirement  shall  not  apply  to  structured  parking or below‐ground parking.    The applicant  has provided a figure  demonstrating  the 10% interior  landscaping  requirement is met.      (3) All interior and perimeter planting shall be protected by curbing unless specifically  designed as a collection and treatment area for management of stormwater runoff  as  per  13.06(B)(5)(c)  below.  Interior  planted  islands  shall  have  a  minimum  dimension of six (6) feet on any one side, and shall have a minimum square footage  of sixty (60) square feet. Large islands are encouraged.     Staff considers this criterion met.    (4)  Landscaping Requirements   (a)   Landscaping shall include a variety of trees, shrubs, grasses and ground covers.  All planting shall be species hardy for the region and, if located in areas receiving road  runoff or salt spray, shall be salt‐tolerant.   (b)   At least one (1) major deciduous shade tree shall be provided within or near the  perimeter of each parking area, for every five (5) parking spaces. The trees shall be  placed evenly throughout the parking lot to provide shade and reduce glare. Trees shall  be placed a minimum of thirty (30) feet apart.    The applicant is proposing 36 parking spaces.  Including the existing tree to be retained,  8 shade trees are proposed.  Staff considers this criterion met.     13.06C Screening or Buffering  (1)  All off‐street parking areas, off‐street loading areas, outdoor storage areas, refuse,   recycling,  and  compost  collection  (excluding  on‐site  composting) areas, and utility  improvements such as transformer(s), external heating and cooling equipment shall be  effectively screened.  (2)  Such screening shall be a permanently maintained landscape of evergreen or a mix of  evergreen and deciduous trees and shrubs, and/or a solid fence.  #SD‐20‐02  Staff Comments 13 13 of 15  (3)  The landscaping shall be designed to minimize erosion and stormwater runoff, and to  protect neighboring residential properties from the view of uses and parking areas on the  site. The landscaping shall be of such type, height, and spacing, as in the judgment of the  Development Review Board, will effectively screen the activities on the lot from the view of  persons standing on adjoining properties. The plan and specifications for such planting shall  be filed with the approved plan for the use of the lot.  (4)  A solid wall or fence, of location, height, and design approved by the Development  Review Board, may be substituted for the required planting.  (5)  Modifications. Where the existing topography and/or landscaping provides adequate  screening or would render the normally required screening inadequate, the Development  Review Board may modify the planting  and/or  buffer  requirements  by,  respectively,  decreasing or increasing the requirements.    As  discussed  above,  though  perimeter  screening  is  limited,  based  on  topography  and  setbacks, Staff considers screening to be adequate.   E.  Modification of Standards. Except within the City Center Form Based Code District, where the  limitations of a site may cause unusual hardship in complying with any of the standards above and  waiver therefrom will not endanger the public health, safety or welfare, the Development Review  Board may modify such standards as long as the general objectives of Article 14 and the City's  Comprehensive Plan are met. However, in no case shall the DRB permit the location of a new structure  less than five (5) feet from any property boundary and in no case shall be the DRB allow land  development creating a total site coverage exceeding the allowable limit for the applicable zoning  district in the case of new development, or increasing the coverage on sites where the pre‐existing  condition exceeds the applicable limit.    As discussed at sketch, the applicant is requesting a waiver of side and rear setbacks in order to create a  more logical and attractive layout.  Staff recommends the Board accept the applicant’s waiver request.    F.  Low Impact Development. The use of low impact site design strategies that minimize site  disturbance, and that integrate structures, landscaping, natural hydrologic functions, and various  other techniques to minimize runoff from impervious surfaces and to infiltrate precipitation into  underlying soils and groundwater as close as is reasonable practicable to where it hits the ground, is  required pursuant to the standards contained within Article 12.    See discussion under PUD criterion 11 above.    G.  Standards for Roadways, Parking and Circulation. Standards of Section 15.12 Standards for  Roadways, Parking, and Circulation shall be met.    See discussion under PUD Criterion 3 above.      CONDITIONAL USE REVIEW    Pursuant to Section 3.07D(1) of the South Burlington Land Development Regulations (Waiver of Height  Requirements for Rooftop Apparatus), the proposed use shall be reviewed as a conditional use and shall  meet the following standards of Section 14.10(E):    14.10E General Review Standards  #SD‐20‐02

Purpose of this plat is to depict the boundaries and easements associated with Lot 1Aformerly of "Meadowlands Business Park".2. Field survey was conducted during fall-winter 2006-2007 and consisted of a closed looptraverse utilizing electronic total station instruments. Lot 1A boundaries as-set werere-surveyed fall 2019, so bearings & distances may vary slightly from previous plats. Bearingsshown are from Grid North, Vermont Coordinate System of 1983, based upon our RTK GPSobservations on/near the site.3. Corner markers set typically consist of 5/8" x 40" steel rebar or 4" square concretemonuments with aluminum caps or disks stamped "Civil Engineering Assocs. - VT LS 597",set flush with existing grade.4. Concrete monuments found are 4" square unless otherwise noted. Iron pipes found are 1"inside diameter unless otherwise noted. Iron rods found are 5/8" diameter unless otherwisenoted.5. Vermont Route 116, also known as "Hinesburg Road" is a public highway with a recordwidth of 4 rods (66 feet). The sideline shown here abutting the subject parcel is based uponour analysis of monumentation found and the referenced plat.

Allconstruction sites are fluid in their day to day exposures and risks as itrelates to minimizing sediment loss from the site. It is theresponsibility of the Contractor to implement the necessary BMP'sto comply with the Erosion Prevention and Sediment Control FieldGuide standards outlined on this sheet based on the interim sitedisturbance conditions which may or may not be shown on theEPSC Site Plan.This project is authorized to disturb up to 2.3 acres1. Pre-Construction PlanningPlanning your construction project can help you avoid costly mistakes incontrolling erosion and sediment loss to nearby waterways. Follow the steps belowbefore you begin clearing, grading, and excavation work. If your project is one acreor larger, you will need a construction stormwater permit from the VermontDepartment of Environmental Conservation (VT DEC) Stormwater Section(802-828-1535, or see dec.vermont.gov/watershed/stormwater)Assess soils and slopes on the construction siteThe erosion potential on your construction site depends in part on the soil typeand slope steepness at your site. See the table below.Note: there are other factors that contribute to erosion, such as slope length andrainfall intensity and duration. Also, even though there may be low potential for erosion,there can be a high risk to water quality when the soil disturbance is close to waterresourcesIdentify nearby streams and drainage control pointsWalk over the site and find where ditches or other concentrated flows leave thesite. These are the final sediment control points. Sediment traps or basins shouldbe installed just above these control points.Your site may drain to an underground storm sewer system. In this case, the stormdrain inlets that drain runoff from your site are the control points and must beprotected (see Section 7). These are also the compliance points for any permitsissued for the site.Install clean water diversions, sediment traps/ basins, grassed ditches, silt checkdams, and sediment barriers such as silt fences before clearing and excavationwork begins!Preserve existing vegetation wherever possibleOnly dig or grade where necessary. Existing trees, bushes, and grass help keeperosion to a minimum. Protect large trees by marking off a no-dig root protectionzone that is twice as large as the outer perimeter of the branches. Plan your projectto limit the amount of bare soil area exposed to the weather, and limit the amountof exposure time. Do not clear vegetation or excavate areas near streams, rivers,lakes, or wetlands without getting the required state and federal permits!Preserve vegetated buffersPreserve existing vegetation near waterways wherever possible. This vegetation isthe last barrier to capture sediment runoff before it enters the lake, river, stream, orwetland. Where vegetation has been removed or where it is absent, plant nativespecies of trees, shrubs, and grasses.Design projects to fit the natural topographyMinimize clearing and grading to preserve mature vegetation and save money.Identify natural landscape features you want to keep, like large trees, wildflowerareas, grasslands, streams, and wetlands. Plan ways to fit your project aroundthese features, so they remain in place after construction is completed. Be sure tomark off these areas with colored ribbon or stakes and warn equipment operatorsof their location!Minimize impervious surfacesKeep the amount of roof area, parking lots, driveways, and roads to a minimum.Design these hard surfaces so that rain water they collect is directed ontolandscaped or yard areas, not into ditches or streams. For example, design roadsslightly higher than adjacent lawn areas, and use swales instead of curbs alongroadways.Promote infiltration in project designMoving storm water runoff from hard surfaces to landscaped or yard areas helpsrunoff soak into the soil. This promotes groundwater recharge, filters sediment andother pollutants from runoff, and helps to prevent flooding.Develop an erosion and sediment control planDevelop a written site plan for your project that shows the drainage patterns andslopes, areas of disturbance (cuts/fills, grading), location of erosion and sedimentcontrols, location of surface waters and wetlands, and the location of storm waterdrainage control points. Your site plan must be updated as conditions change atthe site. Design specifications for erosion prevention and sediment control areincluded in the Vermont Standards and Specifications for Erosion Preventionand Sediment Control.This manual is available for download at: dec.vermont.gov/watershed/stormwater.Ϯ͘ŽŶƐƚƌƵĐƚŝŽŶWŚĂƐĞKƉĞƌĂƚŝŽŶƐŝǀŝĚĞLJŽƵƌĐŽŶƐƚƌƵĐƚŝŽŶƐŝƚĞŝŶƚŽŶĂƚƵƌĂůĚƌĂŝŶĂŐĞĂƌĞĂƐ͕ƐŽLJŽƵĐĂŶĚĞĂůǁŝƚŚĞĂĐŚŽŶĞŝŶĚŝǀŝĚƵĂůůLJ͘zŽƵǁŝůůďĞĐŽŶƚƌŽůůŝŶŐĞƌŽƐŝŽŶŽŶďĂƌĞƐŽŝůĂƌĞĂƐďLJĂƉƉůLJŝŶŐƐĞĞĚ͕ŵƵůĐŚ͕ŽƌƐĞĚŝŵĞŶƚďĂƌƌŝĞƌƐ͕ĂŶĚŵŝŶŝŵŝnjŝŶŐƚŚĞƚŝŵĞďĂƌĞƐŽŝůŝƐĞdžƉŽƐĞĚƚŽƚŚĞǁĞĂƚŚĞƌ͘ŽŶƚƌŽůƉŽŝŶƚƐĨŽƌƐĞĚŝŵĞŶƚŝŶƌƵŶŽĨĨǁŝůůďĞĂƚƚŚĞĐƵƌďŝŶůĞƚƐŽƌŝŶƚŚĞĚŝƚĐŚĞƐ͕ĐŚĂŶŶĞůƐ͕ŽƌƐĞĚŝŵĞŶƚƚƌĂƉƐͬďĂƐŝŶƐŝŶƐƚĂůůĞĚǁŚĞƌĞĐŽŶĐĞŶƚƌĂƚĞĚĨůŽǁůĞĂǀĞƐƚŚĞƐŝƚĞ͘/ŶƐƚĂůůĐůĞĂŶǁĂƚĞƌĚŝǀĞƌƐŝŽŶƐ͕ƐĞĚŝŵĞŶƚƚƌĂƉƐͬďĂƐŝŶƐĂŶĚƐƚĂďŝůŝnjĞĚƌĂŝŶĂŐĞĐŚĂŶŶĞůƐǁŝƚŚŐƌĂƐƐ͕ůŝŶĞƌƐ͕ĂŶĚƐŝůƚĐŚĞĐŬĚĂŵƐďĞĨŽƌĞĞdžĐĂǀĂƚŝŽŶ͕Ĩŝůů͕ŽƌŐƌĂĚŝŶŐǁŽƌŬďĞŐŝŶƐ;ƐĞĞ^ĞĐƚŝŽŶϴͿ͘/ŶƐƚĂůůƐŝůƚĨĞŶĐĞƐĂŶĚŽƚŚĞƌƐĞĚŝŵĞŶƚďĂƌƌŝĞƌƐĚŽǁŶŚŝůůĨƌŽŵďĂƌĞƐŽŝůĂƌĞĂƐďĞĨŽƌĞĐůĞĂƌŝŶŐŽƌĞdžĐĂǀĂƚŝŽŶǁŽƌŬďĞŐŝŶƐ;ƐĞĞ^ĞĐƚŝŽŶϱͿ͘Phase your construction work to minimize exposed soil areasExcavate or place fill material at the site in stages, to avoid exposing large areas ofbare soil to the elements. Projects should be cleared and graded as constructionprogresses. Check your EPSC Plan for your site's permitted disturbance area.Establish final grade quickly, then seed, mulch, or cover bare soil. If work willproceed over several weeks or months, apply temporary seeding or mulch untilfinal grade work is completed. Seed and mulch as soon as possible and as peryour permit requirements. Excavation and grading work should be done duringdry weather if possible. Prepare for rainy weather by making sure sedimentcontrols are in place and that all exposed areas are mulched.Install construction entrances and control dustMud tracked onto roads is the number one complaint from citizens regardingconstruction site operations. Use a matrix of 1 to 4 inch stone for entrance/exitpads leading to roads. Pads should be at least 12 feet wide, 40 feet long, and 8inches deep. Entrance pads shall not be narrower than the construction entrance.On residential properties, pads may be shorter than 40 feet, as long as they are thelength of the driveway. Install filter fabric under the rock to keep it from sinking intothe soil below. Rake rock with a grubbing attachment or add new rock if the padfills with sediment.Control dust during hot, dry weather by seeding or mulching bare areas promptlyor by wetting haul roads as needed.Dewatering operations and dischargesWater pumped from collection basins or other areas must not be pumped intostorm sewers, streams, lakes, or wetlands unless sediment is removed prior todischarge. Discharges to streams, lakes, wetlands, or storm sewers needs tobe part of the authorized EPSC Plan.Use sock filters or sediment filter bags on discharge pipes, discharge water into siltfence enclosures installed in vegetated areas away from waterways, or dischargewater into a de-silting basin. Remove accumulated sediment after water hasdispersed and stabilize or seed the discharge area. Dispose of sediment in areaswhere it won't wash into waterways, then grade the area and seed.Inspection and maintenance of EPSC practicesFor sites one acre or larger, the Vermont Construction General Permit requires thatyou regularly inspect and repair/replace all sedimentation and erosion controlmeasures identified in the EPSC Plan. Discharge locations must also be inspectedto ascertain whether erosion control measures are effective in preventingsignificant impacts to waters of the State. Your inspection reports must be inwriting, and kept with your EPSC Plan at the site. Refer to your construction permitfor inspection requirements.3. Diverting Runoff Around Exposed SoilsKeep clean runoff from flowing through your construction site, or route it throughstable ditches so it won't pick up sediment. Below are some simple,interchangeable approaches for dealing with upland sources of runoff.Earth DikesAn earth dike or berm is a long, mounded “collar” of compacted soil located uphillfrom the excavated area. The dike is designed to intercept overland runoff anddirect it around the construction site. This prevents “clean” water from becomingmuddied with soil from the construction site. Earth dikes can be temporary orpermanent landscape features of the site.Design CriteriaChannel StabilizationConstruction Specifications1. Compact the dike with earth-moving equipment.2. Stabilize the channel as per the specifications in the table within 48 hours ofinstallation.3. Top width may be wider and side slopes flatter if desired to facilitate crossing byconstruction traffic.4. Ensure the dike has positive drainage to an outlet.5. Ensure that there is no erosion at the outlet.6. Runoff shall be conveyed to a sediment trapping device if the dike channel ordrainage area above the dike is not adequately stabilized.7. The earth dike shall remain in place until the disturbed areas are completelystabilized.Diversion SwalesDiversion swales are similar to dikes12/20/2019they are designed to intercept anddivert upland runoff around bare soil areas. Swales are cut above cleared or fillareas and designed with a gentle slope to carry water away from work areas.Stabilized, lined swales can also be used to move upland water through your sitewithout getting muddy. Construct and line “pass-through” swales before generalclearing or grading work begins. Swales should discharge to areas with thickvegetation or flat surfaces to promote dispersal and infiltration. Gullies must berepaired as soon as they appear.Channel Stabilization (see Earth Dike)Construction Specifications1. Compact the swale with earth-moving equipment.2. Stabilize the swale as per the specifications for channel stabilization (see EarthDike).3. Ensure that the swale has uninterrupted positive drainage to an outlet.4. Ensure that there is no erosion at the outlet.5. Diverted runoff from a disturbed area shall be conveyed to a sediment trappingdevice.6. All earth removed and not needed for construction shall be stabilized and placedso that it will not interfere with the functioning of the swale.Perimeter Dike and SwaleA perimeter dike is a temporary ridge of soil excavated from an adjoining swalelocated along the perimeter of the site or disturbed area.Design CriteriaDrainage area - less than 2 acresHeight - 18 inches minimum(measure from bottom of swale to top of dike)Bottom width of dike - 2 feet minimumWidth of swale - 2 feet minimumGrade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet.Construction Specifications1. Stabilize the dike and swale within 48 hours of installation.2. Install berm on the contour (along the slope).3. Diverted runoff from a stabilized upland area shall outlet directly onto anundisturbed, stabilized area at a non-erosive velocity.4. Diverted runoff from a disturbed upland area shall be conveyed to a sedimenttrapping device.Water BarA water bar is a ridge or a ridge and channel constructed diagonally across asloping road that is subject to erosion. Water bars limit the erosive velocity of waterby diverting surface runoff at predesigned intervals.Water Bar Design CriteriaHeight - 18 inches min height(measure from channel bottom to ridge top)Side Slopes - 2:1 or flatter; 4:1 where vehicles crossBase width of ridge - 6 feet minGrade of water bar - not to exceed 2%Construction Specifications1. Install the water bar as soon as the road or trail is cleared and graded.2. Disk or strip the sod from the base for the constructed ridge before placing fill.3. Track the ridge to compact it to the design cross section.4. The outlet shall be located on an undisturbed area. Field spacing will beadjusted to use the most stable outlet areas. Outlet protection will be providedwhen natural areas are not adequate.5. Vehicle crossing shall be stabilized with gravel.Exposed areas shall be immediately seeded and mulched.6. Periodically inspect water bars for erosion damage and sediment. Check outletareas and make repairs as needed to restore operation.4. Protecting Soils With Seed, Mulch, or OtherProductsSeeding or covering bare soil with mulch, erosion control matting or blankets, orother products as soon as possible is the cheapest and best way to preventerosion. Grass seeding alone can reduce erosion by more than 90 percent.The following practices can be used interchangeably for stabilizing exposed soil.Soil cover requirementsAll areas of disturbance must have temporary or permanent stabilization within 7days of initial disturbance. After this time, any disturbance in the area must bestabilized at the end of each work day.The following exceptions apply: Stabilization is not required if earthwork is to continue in the area within the next24 hours and there is no precipitation forecast for the next 24 hours. Stabilization is not required if the work is occurring in a self-contained excavation(i.e. no outlet) with a depth of 2 feet or greater (e.g. house foundation excavation,utility trenches). All areas of disturbance must have permanent stabilization within48 hours of reaching final grade.NOTE: If the authorization you receive has more protective time limits, then thosemust be followed.Seed types and applicationPrepare bare soil for planting by disking across slopes, scarifying, or tilling if soilhas been sealed or crusted over by rain. Seedbed must be dry with loose soil to adepth of 12 inches. Soil amendments should be incorporated into the upper 2inches of soil when feasible. The soil should\ be tested to determine theamounts of amendments needed. Apply ground agricultural limestone to attain apH of 6.0 in the upper 2 inches of soil. Check seed bag tags to make sure correctseed is used. Mix seed thoroughly prior to loading seeders. Use the followingtables to calculate seed application rates and mixture portions. Apply seed byhand, seeder, drill, or hydroseed. Drilled seed should be . inch deep. Mulchseeded areas as soon as possible. Apply more seed to channels, ditches, lawn,and landscaped areas. Apply less seed to areas that are flat or that will not bemowed very often. Water seeded areas during dry conditions to ensure seedgermination and early growth. Re-seed areas that do not show growth within 14days after rain or watering. Protect bare areas during the winter by sowing winterrye at 120 lbs per acre (2.0 lbs/1000 sq. ft.). Seed by September 15 to ensurevegetative cover for winter.Seed mixes for wildflower and native plant plots are also available. They are moreexpensive, but are very hardy, require little mowing or watering, and add beauty tolandscaped and other areas. Most mixes require mowing only once per year, tocontrol tree and brush growth.For slopes steeper than 3:1, walk bulldozer or other tracked vehicle up and downslopes before seeding to create tread-track depressions for catching and holdingseed. Mulch slopes after seeding to conserve moisture and provide initial erosioncontrol.Mulch types and applicationMulch by itself or applied over seed provides excellent erosion protection (seetable). To apply, bring site to final grade and clear rocks, wood, trash, and otherdebris. Apply seed first. Straw or hay should be hand scattered or blown to obtaina depth of 1 inch (see table). In winter, straw or hay mulch should be applied toobtain a depth of 3 inches. Wood chips or shavings should be applied to a depthof 2 inches.In general, apply mulch so that at least 80 to 90 percent of the ground is covered.*Perform regular maintenance and reapply mulch as needed to ensure baresoil is 80 to 90% covered.Erosion control blanketsErosion control blankets are used to protect steep slopes (up to 3:1; checkproduct information sheets), drainage ditches with less than 20:1 slopes, and otherareas where erosion potential is high. Most are designed to provide temporarystabilization until vegetation is established. Blankets degrade within 6 to24 months, depending on their makeup. They usually consist of a layer of straw,coconut fiber, wood fiber, or jute sandwiched between layers of plastic or fibermesh.For short slopes (8 feet or less) above channels, install blankets across the slope(horizontal). Install up and down the hill (vertical) for long slopes.Walk blankets down to ensure good contact with the soil. Use plenty of staples tokeep blankets flat.Overlap blankets at 6 to 8 inches on sides, tops, and bottoms. Do not stretchblankets, and do not exceed manufacturer's directions on maximum slope anglefor the product.Turf reinforcement matsTurf reinforcement mats are similar to erosion control blankets, but are thicker andsturdier because they have more layers and sturdier fill material. Mats providegreater protection than blankets because of their heavier construction, and lastlonger in the field.Mats are used for steep slopes (3:1 or steeper) and ditches or channels with 15:1to 10:1 slopes.Mats are installed just like blankets (see previous table). Additional staking orstapling is needed for applications in channels that carry flowing water, and onsteep slopes.Sod applicationSod reduces the potential for erosion to near zero. To install, bring soil to finalgrade and clear of trash, wood, rock, and other debris. Test soil, apply topsoil andfertilize in accordance with soil test results. Use sod within 36 hours of cutting. Laysod in straight lines. Butt joints tightly, but do not overlap joints or stretch sod.Stagger joints in adjacent rows in a brickwork type pattern. Use torn or unevenpieces on the end of the row. Notch into existing grass. On sloping areas whereerosion may be a problem, sod shall be laid with the long edges parallel to thecontour and with staggered joints. Roll or tamp sod after installation and waterimmediately. Soak to a depth of 4 to 6 inches. Replace sod that grows poorly. Donot cut or lay sod in extremely wet or cold weather. Do not mow regularly until sodis well established.Bonded Fiber MatricesOther engineered products are available that are similar to blankets and mats. Forexample, bonded fiber matrices and other hydraulically applied products contain amix of soil binders, mulch fibers, and even seed and fertilizer that can provide astable crust that cements soil particles and prevents erosion. Apply seed prior tohydraulic mats or mulches, if seed is not included in the mix. Consult themanufacturer's installation instructions for product applicability and installationinstructions.5. Using Silt Fence and Other Sediment BarriersThe use of silt fences and other sediment barriers involves simple observation andcommon sense. However, as Will Rogers once noted, “common sense ain't socommon.” The following practices may be used as interchangeable sedimentbarriers.Sediment barrier placementSediment barriers are required below (downhill from) areas of bare soil. Hay orstraw bales must not be used as sediment barriers due to their inherent weaknessand tendency to fall apart. There are several factors to consider in placing siltfences or perimeter dikes and swales: Place barriers on downhill edge of bare soil areas. Make sure the barrier catches all the runoff. The goal is to intercept runoff and settle sediment out. Install multiple sediment barriers on long slopes. Put barriers across slopes, on the contour (level).Silt FenceEach 100-foot section of silt fence can intercept runoff from about .25 acres. Toinstall a silt fence correctly, follow these steps: Note the location & extent of the bare soil area. Mark silt fence location just below bare soil area or 10 feet below the bottom of asteep slope. Make sure fence will catch all flows from area. Place fence across the slope. Dig trench 6 inches deep and 4 inches wide. Unroll silt fence along trench. Join fencing by rolling the end stakes together. Make sure stakes are on downhill side of fence. Drive stakes in against downhill side of trench. Drive stakes until 16 inches of fabric is in trench. Push fabric into trench; spread along bottom. Fill trench with soil and tamp down.Silt fencing should not be installed: Up and down hills. Above (uphill from) areas of bare soil. In ditches, channels, or streams. In stream buffers. Directly at the toe (bottom) of the slope. Additional storage capacity is needed andcan be provided for by placing the fence 10 feet below toe. (Place fence directly attoe if near water or stream buffer)If runoff flows along the uphill side of a siltfence, install “J-hooks” every 40 to 80 feet. These are curved sections of silt fencethat act as small dams to stop, pond, and settle out flows.Maximum allowable slope lengths contributingrunoff to a silt fence placed on a slopeSilt fence slicing devicesNew tractor-mounted equipment that “slices” silt fence into the ground can providea better installation than the open trench method. The equipment uses achisel-point or vibratory plow to create a narrow slit in the ground. Rolled siltfencing is pushed into the slit, creating a very tight seal that prevents water fromblowing out the bottom of the fence. Posts are driven and attached to the fenceafter the fencing is installed.Besides better performance, the slicing method is also faster. For slicing and allother applications, posts are spaced 6 feet apart or less.Perimeter Dike and SwaleA perimeter dike is a temporary ridge of soil excavated from an adjoining swalelocated along the perimeter of the site or disturbed area. The purpose of aperimeter dike and swale is to prevent off site storm runoff from entering adisturbed area and to prevent sediment laden storm runoff from leaving theconstruction site or disturbed area.Perimeter Dike and Swale Design CriteriaDrainage area - less than 2 acresHeight - 18 inches minimum (measure from bottom of swale to top of dike)Bottom width of dike - 2 feet minimumWidth of swale - 2 feet minimumGrade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet.Construction Specifications1. Stabilize the dike and swale within 48 hours of installation.2. Install berm on the contour (along the slope).3. Diverted runoff from a stabilized upland area shall outlet directly onto anundisturbed, stabilized area at a non-erosive velocity.4. Diverted runoff from a disturbed upland area shall be conveyed to a sedimenttrapping device.6. Protecting Slopes to PreventGulliesSlopes12/20/2019especially long ones12/20/2019must be protected to preventsheet, rill, and gully erosion. Slopes must be stabilized immediately after gradingwork is completed. The following practices can be used interchangeably to protectand stabilize slopes:The following practices are included in this section for informational purposes only.Consult the EPSCPlan designer or engineer for design and installation specifications.Pipe Slope Drain Subsurface Drain Lined WaterwayEngineered Terracing Surface Roughening Retaining Wall Fiber RollAssessing slopes and soilsSteeper slopes (3:1 or steeper) require more protection than flatter slopes. Slopeswith highly erodible soils (silty soils) need more protection than those with lesserodible soils (sands and gravels).Also, long slopes (greater than 50 feet) are at greater risk for erosion than shortslopes.Slope protection basicsProtecting slopes from erosion requires several actions that must be taken together. No singleapproach will be successful, especially if the slope is long, steep, or has highly erodible soils.Use one or more of the following actions to reduce erosion on slopes:Divert upland runoffSee Section 3 for information on how to install a berm or channel above the slope to divertupland rain runoff around the bare soil area.Control slope runoffIf slopes are broken up into benches or steps, runoff can be collected and diverted along bermsor in channels to pipe or open channel slope drains with stable outlets.Till seedbed or condition the soilDozer tracks up and down slopes help hold soil in place and lengthen the runoff flow path downthe slope. See Section 4 for information on how to condition of the soil surface.Seed and mulchThe best and cheapest protection by far. See Section 4 for details on seed types, applicationrates, and mulch, blanket, and mat products.Silt fence or other barrierThese should be installed at the toe of the slope or slightly away from the toe. Multiple fencesshould be installed on long slopes. Fiber rolls installed on the contour work very well in breakingup flows on long slopes.Retaining wallExtremely steep slopes can be leveled out and shortened into two or more steps or benches byinstalling retaining walls of rock, brick, block, wood, logs, or other material. If rock layers arepresent along the slope, use these to establish firm benches in a stair-step pattern.Blankets, mats, or armoringSlopes exceeding 3:1 with highly erodible soils must be protected with turf reinforcement matsor other products such as hydraulic soil binders or bonded fiber matrices. Rock mulch and lineddowndrain channels might be needed on steep slopes to control gullying.Erosion Control Blankets and MatsSteep slopes can be protected with erosion control mats and blankets. Erosioncontrol matting and blankets are appropriate for slopes up to a 3:1 steepness. Forslopes greater than 3:1, use turf reinforcement mats. (See Section 4 for installationdetails).Hydraulic mulchBonded fiber matrices and hydraulic mulch can be very effective in controllingerosion on slopes. Hydraulic mulch applied after seeding or with seed in the mixcan provide permanent protection if mixed and applied properly. (See Section 4 fordetails)Rock GabionsRock Gabions are wire 'baskets' filled with rock used to permanently stabilizeslopes. Gabion baskets should be filled with 4 - 8 inch stone and layeredaccording to manufacturers recommendations.Riprap Slope ProtectionRiprap is a layer of stone designed to protect and stabilize areas subject toerosion. Riprap is used in areas where vegetation cannot be established. Followyour EPSC Plan design specifications for installation.Additional Practices for Protecting SlopesThe following practices are included in this section for informational purposes only.Consult the EPSCPlan designer or engineer for design and installation specifications.Pipe Slope DrainA pipe slope drain is a temporary structure placed from the top to the bottom of aslope to convey runoff down the slope without causing erosion.Subsurface DrainA subsurface drain is a conduit, such as a tile, pipe, or tubing installed beneath theground surface that intercepts, collects, and/or conveys drainage water.^ƚŽŶĞ>ŝŶĞĚtĂƚĞƌǁĂLJƐƚŽŶĞůŝŶĞĚǁĂƚĞƌǁĂLJŝƐĂĐŚĂŶŶĞůƚŚĂƚĐĂƌƌŝĞƐǁĂƚĞƌĚŽǁŶĂƐůŽƉĞƚŽƉƌĞǀĞŶƚƐůŽƉĞĞƌŽƐŝŽŶŽƌŐƵůůLJŝŶŐ͘ŶŐŝŶĞĞƌĞĚdĞƌƌĂĐŝŶŐdĞƌƌĂĐŝŶŐŝƐƚŚĞƌĞƐŚĂƉŝŶŐŽĨƚŚĞĞdžŝƐƚŝŶŐůĂŶĚƐƵƌĨĂĐĞƚŽĐŽŶƚƌŽůĞƌŽƐŝŽŶĂŶĚƉƌŽŵŽƚĞƚŚĞĞƐƚĂďůŝƐŚŵĞŶƚŽĨǀĞŐĞƚĂƚŝŽŶ͘^ƵƌĨĂĐĞZŽƵŐŚĞŶŝŶŐZŽƵŐŚĞŶŝŶŐďĂƌĞƐŽŝůďLJĐƌĞĂƚŝŶŐŚŽƌŝnjŽŶƚĂůŐƌŽŽǀĞƐĂĐƌŽƐƐĂƐůŽƉĞ͕ƐƚĂŝƌͲƐƚĞƉƉŝŶŐ͕ŽƌƚƌĂĐŬŝŶŐǁŝƚŚĐŽŶƐƚƌƵĐƚŝŽŶĞƋƵŝƉŵĞŶƚĂŝĚƐŝŶƐĞĞĚĞƐƚĂďůŝƐŚŵĞŶƚ͕ƌĞĚƵĐĞƐƌƵŶŽĨĨǀĞůŽĐŝƚLJ͕ŝŶĐƌĞĂƐĞƐŝŶĨŝůƚƌĂƚŝŽŶ͕ĂŶĚƌĞĚƵĐĞƐĞƌŽƐŝŽŶďLJƚƌĂƉƉŝŶŐǁĂƚĞƌĂŶĚƐĞĚŝŵĞŶƚ͘Retaining WallA retaining wall is constructed against a slope to prevent soil movement. It retainssoil in place and prevents slope failures and movement of material down steepslopes.Retaining walls can be built from mortared block or stone, cast-in-place concrete,railroad ties, gabions, and precast, modular, segmented walls. The design of anyretaining wall structure must address the aspects of foundation bearing capacity,sliding, overturning, drainage, and loading systems. These are complex systemsand all but the smallest retaining walls should be designed by a licensed engineer.Fiber RollA fiber roll is a woven roll of coconut fiber, straw, or excelsior encased in a nettingof jute, nylon, or burlap.Fiber rolls can be used to break up runoff flows on long slopes.7. Protecting Culvert and Ditch Inlets and OutletsCulverts and ditches are designed to carry moderate and large flows of stormwater. They can transport a lot of sediment to streams, rivers, wetlands, and lakesif they are not properly protected. In addition, culvert and ditch outlets can becomeseverely eroded if high velocity flows are not controlled.Culvert and storm drain ponding methodsMuddy runoff that flows toward a culvert, ditch, or storm drain inlet must be sloweddown and pooled to settle out and remove sediment. This can be accomplished byplacing rock, reinforced silt fencing, silt dikes, or other barrier in front of the inlet.The goal is to cause ponding of the inflow so sediment can settle out, and allowponded water to enter the inlet only after sediment has been removed.Straw bales alone are not approved for inlet protection. The maximumdrainage area above the inlet protection device is one acre. For all inletprotection approaches, seeding and/or mulching upland areas promptly willgreatly reduce incoming runoff volumes and sediment loads. The drainage areafor storm drain inlets shall not exceed one acre.All inlet protection practices should be inspected after storm events and repairedas necessary. Accumulated sediment should be removed when 50% of pondingvolume is lost. The following are interchangeable practices for inlet protection:Excavated drop inlet protectionSide slopes - maximum steepness 2:1Depth - minimum 1 foot; maximum 2 feetShape the excavated basin to fit conditions with the longest dimension orientedtoward the longest inflow area to provide maximum trap efficiency. The capacity ofthe excavated basin, below the level of the grate, should be established to contain900 cubic feet per acre of disturbed area. Weep holes, protected by fabric andstone, should be provided for draining the temporary pool. Inspect and clean theexcavated basin after every storm. Sediment should be removed when 50 percentof the storage volume is lost.Filter fabric drop inlet protectionSlope around device - Not to exceed 1%Height of fabric - 1.5 feet max., (unless reinforced).The top of the barrier should be maintained to allow overflow to drop into the dropinlet and not bypass the inlet to unprotected lower areas.Support stakes - 3 feet min., spaced max 3 feet apart; Stakes should be drivenclose to the inlet so overflow drops into the inlet and not on the unprotected soil.1. Filter fabric shall have an equivalent opening size (EOS) of 40-85.2. Cut fabric from a continuous roll to eliminate joints.3. Stakes will be standard 2 x 4 inch wood or metal with a minimum length of 3feet.4. Space stakes evenly around inlet, 3 feet apart and 18 inches deep. Spansgreater than 3 feet should be reinforced with wire mesh.5. Fabric shall be embedded at least 1 foot in ground and backfilled. It should besecured to the stakes.6. A 2 x 4 inch wood frame shall be completed around the crest of the fabric foroverflow stability.Stone and block drop inlet protectionHeight - 1 foot min., 2 feet max. Limit the height to prevent excess ponding andbypass flow.Block placement - Recess the first row of blocks at least 2 inches below the top ofthe storm drain for lateral support. Blocks can also be supported by placing a 2x4inch wood stud through the block openings perpendicular to the row. The bottomrow should have a few blocks oriented so flow can drain through the block todewater the basin area.Stone placement - Place stone just below the top of the blocks on slopes of 2:1 orflatter. Place hardware cloth of wire mesh with . inch openings over all blockopenings to hold stone in place.Optional "doughnut" design - The concrete blocks may be omitted and the entirestructure constructed of stone, ringing the outlet. The stone should be kept at a 3:1slope toward the inlet to keep it from being washed into the inlet. A level area 1foot wide and four inches below the crest will further prevent wash.Stone size for "doughnut" - At least 3 inches closest to the inlet, for stability; 1inch or smaller around the larger rock to control flow rate.Elevation for "doughnut" - The top of the stone should be 6 inches lower than theground elevation down slope from the inlet to ensure that all storm flows pass overthe stone into the storm drain and not past the structure. Temporary diking shouldbe used as necessary to prevent bypass flow.Curb drop inlet protectionStone size - 2 inchesWire mesh - of sufficient strength to support the filter fabric and stone with thewater fully impounded against it.Filter fabric - type approved for this purpose with an equivalent opening size(EOS) of 40-85.Length of structure - must extend beyond the inlet 2 feet in both directions.Assure that storm flow does not bypass the inlet by installing temporary dikes(such as sand bags) directing flow into the inlet. Make sure that the overflow weir isstable. Traffic safety shall be integrated with the use of this practice.The structure should be inspected after every storm event. Any sediment should beremoved and disposed of on the site. Any stone missing should be replaced.Check materials for proper anchorage and secure as necessary.Outlet protection methodsOutlets for storm drains, culverts, and paved channels that discharge into naturalor constructed channels must be lined with rock or other armoring to preventdownstream bank and channel erosion when flow velocities are high.The following practices are included in this section for informational purposes only.Consult the EPSCPlan designer or engineer for design and installation specifications.

Consult the EPSC Plan designer or engineer fordesign and installation specifications for steep channel protection.Vegetating Low Grade ChannelsVegetating drainage channels helps to reduce the velocity of the channelizedrunoff and limit the erosion potential. The following practices can be usedinterchangeably to vegetate low grade channels.Seed and MulchTo establish vegetation in a channel, seed and mulch using the guidance inSection 4. Prepare the soil for seeding and ensure that vegetation is wellestablished before water is diverted to the channel.Rolled Erosion Control Products (RECPs)Rolled Erosion Control Products (RECPs) include erosion control mats, turfreinforcement mats, and jute and excelsior matting. RECPs should be used inchannels with flow velocities up to 3.5 feet/sec. See Section 4 for installationinstructions and seeding information.SoddingSod can also be used in low grade channels to reduce runoff velocities andminimize erosion potential. See Section 4 for sod installation instructions andspecifications.Protecting Steep ChannelsChannels with grades steeper than 3:1 may need additional armoring to preventdowncutting and erosion.The following practices are included in this section for informational purposes only.Consult the EPSC Plan designer or engineer for design and installationspecifications. Rock Lining Grade Stabilization StructureRock LiningRiprap lined channels provide for the transport of concentrated runoff withoutdamage from erosion, where vegetated channels would be inadequate due to highvelocities.Grade Stabilization StructureGrade stabilization structures control head cutting in natural or man madechannels. They are designed to limit erosion by reducing velocities and grade inthe watercourse.Installing Check DamsDrainage ditches need temporary check dams to capture sediment and reduceditch bottom downcutting. The following are interchangeable types of check dams.Silt fencing and hay bales are not approved for use as check dams, and must notbe used in drainage ditches that carry flowing water. Also, do not place dams increeks or streams. Sediment must be intercepted before it reaches streams, lakes,or wetlands.Design CriteriaDrainage Area: Maximum 2 acresHeight: No greater than 2 feet. Center of dam should be 9 inches lower than theside elevationSide slopes: 2:1 or flatterSpacing: Space the dams so that the bottom (toe) of the upstream dam is at theelevation of the top (crest) of the downstream dam. This spacing is equal to theheight of the check dam divided by the channel slope.Spacing (in feet) = Height of check dam (in feet) Slope in channel (ft/ft)Check dams should be anchored in the channel by a cutoff trench 1.5 feet wideand 0.5 feet deep and lined with filter fabric to prevent soil migration.Maintenance: Check dams should be inspected after each runoff event. Correct alldamage immediately. If significant erosion has occurred between structures, a linerof stone or other suitable material should be installed in that portion of the channel.Remove sediment accumulated behind the dam as needed to allow channel todrain through the check dam and prevent large flows from carrying sediment overthe dam. Replace stone, fiber roll, or sand bags as needed to maintain the designcross section of the structures.Rock Check DamsStone size: Use a well graded matrix of 2 to 9 inch stoneX (spacing) = Height of check dam (in feet) Slope in channel (ft/ft)Fiber RollsFiber rolls may be used as check dams if they are keyed into the banks, securelyfastened in the channel, and the centers are 9 inches lower than the sideelevations. Follow the spacing and installation instructions for "Installing CheckDams".Sand Bag Check DamsSand bags may also be used to form check dams. Follow the installation andspacing instructions in "Installing Check Dams" at the beginning of this section.9. Winter RequirementsManaging construction sites to minimize erosion and prevent sediment loading ofwaters is a yearround challenge. In Vermont, this challenge becomes even greaterduring the late fall, winter, and early spring months.'Winter construction' as discussed here, describes the period between October 15and April 15, where the erosion prevention and sediment control is significantlymore difficult.Rains in late fall, thaws throughout the winter, and spring melt and rains canproduce significant flows over frozen and saturated ground, greatly increasing thepotential for erosion. At the same time as the erosion riskincreases, the “toolbox” available to the planner and on-site plan coordinatorshrinks significantly.In particular, establishing vigorous vegetation during winter construction is difficultif not impossible in most areas of the state. How a site addresses winter conditionsdepends upon the nature of the construction activities over this period.10 Closing Out Your Construction ProjectWhen construction is complete you must finish final grading and stabilize the site. Once the site is stabilized, clean out and remove alltemporary sediment controls.Final site stabilizationMake sure all subcontractors have repaired their work areas prior to final closeout. Conduct a final inspection of all work areas, vegetation,stormwater flow structures, and downstream receiving waters to make sure no visible gullies or sediment movement is evident. Notify siteowner or manager after all temporary erosion and sediment controls have been removed and final stabilization has been completed. If thesite is one acre or larger and covered under a VT Storm Water Permit, submit a Notice of Termination to the VT Stormwater Section (seedec.vermont.gov/watershed/stormwater).Vegetated cover considerations for close-outNo site is closed out properly until vegetation is established on all bare soil areas and ditches are stable. Check seeded areas, and reseedareas where vegetation is thin or absent. This is especially important for slopes, ditches, and channels.Removing temporary sediment controlsWhen project is completed: Remove all silt fencing and stakes. Grade out and seed or remove accumulated sediment or broadcast over grassed areas or dispose ofoffsite, where sediment will not impact waters of the State. Culvert inlets should be stabilized, vegetated, and showing no visible gullies. Rock or soil that has been washed away by runoff or upstreamflows should be replaced. Brush or other debris that could clog inlets should be removed. Check ditches and channels to make sure banks and ditch bottoms are well vegetated. Reseed bare areas and replace rock that hasbecome dislodged. Check areas where erosion control blankets or matting was installed. Cut away and remove all loose, exposed material, especially in areaswhere walking or mowing will occur. Reseed all bare soil areas. Replace rock washouts near culvert and channel outlets. Fill, grade, and seed or riprap eroded areas around inlets and outlets. Make suredownstream ditches and channels are fully vegetated. Fill and seed any gullies along the banks or other slopes. Fill in, grade, and seed all temporary sediment traps and basins that have been removed. Double the seeding rate where runoff flows mightconverge or high velocity flows are expected. Remove temporary stream crossings and grade, seed, or re-plant vegetation removed during crossing installation.AcknowledgementsDesign details and standards for erosion prevention and sediment control practices have been adapted from the New York State Standards and Specifications forErosion and Sediment Control.

At the same time as the erosion risk increases, the “toolbox” availableto the contractor and on-site plan coordinator shrinks significantly over this period (Table 3.4 below).In particular, establishing vigorous vegetation during winter construction is not possible. Based upon the activities anticipated to beundertaken during this period, the Contractor shall plan and implement the following Winter EPSC measures.EPSC Plan Requirements for -Winter Shutdown-For those projects that will complete earth disturbance activities prior to the winter period (October 15), the following must beimplemented by the Site Contractor in coordination with the On-Site Plan Coordinator:1. For areas to be stabilized by vegetation, all seeding shall be completed no later than September 15 to ensure adequategrowth and cover.2. Non-vegetative stabilization of all areas of disturbed soils without existing vegetation shall be completed no later than October15.3. When mulch is used as a temporary means of stabilization, the rate of application shall be double that of the regularconstruction season rate, or roughly 2 inches of mulch with 80-90% cover. Mulch should be tracked in when weather permitsor stabilized with netting or an approved tackifier.EPSC Plan Requirements for -Winter Construction-If construction activities involving earth disturbance continue past October 15 or beginbefore April 15, the following must be implemented by the Owner/Site Contractor:This project is seeking winter (March - April) waiver construction authorization.1. Enlarged stabilized access points to provide for snow stockpiling.2. Limits of disturbance flagging moved or replaced to reflect the boundaries of winter work.3. A snow management plan which implements the following requirements:a. adequate storage and control of snowmelt by diverting these flows around the work area,b. cleared snow is to be stored down gradient of all areas of disturbancec. Storage of snow in stormwater treatment structures is prohibited.d. All drainage structures shall be kept open and free of snow/ice.e. buffer is to be maintained from the perimeter controls such as silt fence to allow for snow clearing and maintenance.f. Install silt fence a minimum of 25 feet down gradient of areas of disturbance and snow storage areas. Reinforce fence inareas where snow load forces may be an issue due to site constrictions.4. In areas of disturbance within 100 feet of a receiving water, silt fence shall be reinforced or else replaced with perimeter dikes,swales, or other practices resistant to the forces of snow loads.5. All silt fence and other practices requiring earth disturbance shall be installed ahead of ground freezing.6. Where mulch is the selected stabilization measure, the mulch shall be installed at double the standard rate of mulch, orroughly 2 inches of mulch with 80-90% cover.7. Mulch should be tracked in when weather permits or stabilized with netting or an approved tackifier to prevent removal bywind.8. To ensure cover of disturbed soil in advance of a melt event, areas of disturbed soil must be stabilized at the end of each workday, with the following exceptions:a. If no precipitation within 24 hours is forecast and work will resume in the same disturbed area within 24 hours, dailystabilization is not necessary.b. Disturbed areas that collect and retain runoff, such as house foundations or open utility trenches.”9. Directions to remove snow or ice to less than 1” thickness prior to temporary or permanent stabilization.10. Stone stabilization shall be installed a width of 10 to 20ft wide around the perimeter of buildings under construction, whereconstruction vehicle traffic is anticipated.12/20/2019DSMDSMMAB06248LOCATION MAP1" = 2000'CEA PROPERTIES,LLC10 MANSFIELD VIEW LANESOUTH BURLINGTONVERMONT 05403CEA CAMPUSPLANNED UNITDEVELOPMENTLOT 1AMEADOWLAND BUSINESS PARK SOUTH BURLINGTON, VTMEADOWLAND DR.KNOLLMILL POND LN.FOX RUN LANEOAK CREEK DR.BUTLER DRIVEDUBOIS DRIVECIRCLE HINESBURG ROADCOMMUNITY DR.PROJECTLOCATION8911601/29/20 DSM ACT 250 SUBMITTAL3?$XWR&$''3URMHFWV???&$'')LOHV?GZJ?'(7$,/663(&GZJ30':*7R3')SF AS SHOWNC4.0SITE DETAILSACEN.T.S.CURB w/SIDEWALK DETAILREVISED 10/07/2015S-001(SIMILAR WITH OUT SIDEWALK)S-001 CurbCRUSHED GRAVEL (FINE)DENSE GRADEDSUB-BASE MATERIALNOTES:1.

We understand that any proposed changes to this aesthetic or footprint would require a future application amendment review process. Beyond the south building footprint change,the additional changes that have been integrated into the application package include a strengthened open space design.All of the site plans and landscaping plans have been updated to reflect this concept prepared by Wagner Hodgson Landscape Architects. We have updated the following documents to reflect the change in the south building footprint and total GSF. 1.Application Form (slight reduction in building and lot coverage) and a reduction in PM peak traffic due to the elimination of the specialty veterinary use.The estimated date of completion of the south building is pushed back to late 2021.And 5 years from approval for all three buildings. 2.Avg. Existing Grade Comp.–This has been updated to reflect the revised footprint.It changed the base elevation from 383.2 to 382.4. Based on the change in the proposed type of building, we are now seeking a height waiver for the cupola portion of Building C as outlined below.This description replaces that in the original cover letter. Building C -The most southerly of the two proposed buildings is proposed to be very similar to the existing building currently housing Civil Engineering Associates. This building has a footprint of approximately 3,600 SF and has two stories.The first floor Ms.Marla KeenePage2of2 February 20, 2020 elevation of 386.1 is 3.7 feet above the average existing grade of 382.4. The ridge lineof the building is set at elevation 418.4 resulting is a maximum ridgeline height of the building above average existing grade of 36.0 feet.The proposed cupola extends to elevation 425.2 which is 2.8 feet above the 40-foot maximum for pitched rooves in the IO District.Based upon the opportunity outlined in Article 3, section 3.07 Height ofStructuressubsectionD. Waiver of Height Requirements (2)(b), the applicant seeks awaiver of 2.8 feet from the Development Review Board for the proposed cupola of Building C as the character of the building and placement on the lot achieves the goal that the structure will not detract from scenic views from adjacent public roadways and other public rights-of-way. 3.Traffic Generation –We have attached the updated traffic generation spreadsheet which indicates without the veterinary specialty use that the PM peak hour traffic generation was reduced from 42 to 32 VTEs. The findings of the originally submitted traffic study remain valid as the anticipated traffic generation has been reduced. This completes our summary of the changes made to the pending application package. We recognize that this information may be tardy to still be eligible for the March 4, 2020 DRB hearing. Please let us know your thoughts on this matter.If you should have any questions, please feel free to contact me at 864- 2323 x310. Respectfully, David S. Marshall, P.E.
