Box 1206 Williston, VT 05495 LAWS/REGULATIONS INVOLVED 10 V.S.A. §§ 6001 - 6092 (Act 250) District Environmental Commission #4 hereby issues Land Use Permit Amendment 4C0526-12, pursuant to the authority vested in it by 10 V.S.A. §§ 6001-6092. This permit amendment applies to the lands identified in Book 184, Pages 316-319, of the land records of the City of South Burlington, Vermont, as the subject of a deed to the Harbor Heights Homeowners Association, the Permittee as Grantee. This permit specifically authorizes the Permittee to construct a 90' x 20' subsurface runoff detention structure installed behind units #701-#704. Additional storm sewer piping to be installed to convey runoff to structure. Sediment removal to be provided by a swirl concentrator. The project is located on Harbor View Road in the City of South Burlington. The project is subject to Act 250 jurisdiction because the project is a material change to a development over which the Commission has jurisdiction and thus a land use permit amendment is required pursuant to Act 250 Rule 34. The Permittee, and its assigns and successors in interest, are obligated by this permit to complete, operate and maintain the project as approved by the District Commission in accordance with the following conditions: 1. All conditions of Land Use Pen -nit #4C0526 and amendments are in full force and effect except as amended herein. 2. Representatives of the State of Vermont shall have access to the property covered by this permit, at reasonable times, for the purpose of ascertaining compliance with Vermont environmental and health statutes and regulations and with this permit. 3. The project shall be completed, operated and maintained in accordance with: the plans and exhibits on file with the District Environmental Commission, and the conditions of this permit. 4. The approved plans are: Sheet 1 - "Overall Site Plan, Harbor Heights" dated 3/19/09, last revision 4/13/09; Sheet 2 - "Stormwater Treatment Plan, Harbor Heights" dated 3/19/09, last revision 4/13/09; and Sheet 3 - "Stormwater Treatment Details, Harbor Heights" dated 3/19/09, last revision 4/13/09. Land Use Permit 94CO526-12 Page 2 of 4 5. A copy of this permit and approved plans shall be on the site at all times throughout the construction process. 6. No changes shall be made in the design or use of this project without the written approval of the District Coordinator or the Commission, whichever is appropriate under the Act 250 Rules. 7. Pursuant to Act 250 Rule 51(G), the permit application and material representations relied upon during the review and issuance of this permit by the District Commission shall provide the basis for determining future substantial and material changes to the approved project and for initiating enforcement actions. 8. The District Environmental Commission maintains continuing jurisdiction during the lifetime of the permit and may periodically require that the permit holder file an affidavit certifying that the project is being completed, operated and maintained in accordance with the terms of the permit, as provided by 10 V.S.A. §§ 6001-6092 and the rules of the Natural Resources Board (Act 250 Rules). 9. The conditions of this permit and the land uses permitted herein shall run with the land and are binding upon and enforceable against the Permittee and their successors and assigns. 10. The Permittee shall apply and maintain calcium chloride and/or water on all roadways or disturbed areas within the project during construction and until pavement and/or vegetation is fully established to control dust. 11. There shall be no floor drains installed at the facility without first acquiring the required Underground Injection Control Permit from the Water Supply Division of the Agency of Natural Resources. 12. The Permittee and all subsequent owners or lessees shall install and maintain only low -flow plumbing fixtures in any buildings. Any failed water conservation measures shall be promptly replaced with products of equal or better performance. 13. The Permittee shall comply with Exhibit #22 for erosion control. The Permittee shall prevent the transport of any sediment beyond that area necessary for construction approved herein. All erosion control devices shall be periodically cleaned, replaced and maintained until vegetation is permanently established on all slopes and disturbed areas. The Commission reserves the right to schedule hearings and site inspections to review erosion control and to evaluate and impose additional conditions with respect to erosion control as it deems necessary. 14. All mulch, siltation dams, water bars and other temporary devices shall be installed immediately upon grading and shall be maintained until all roads are permanently surfaced and all permanent vegetation is established on all slopes and disturbed areas. Topsoil stockpiles shall have the exposed earth completely mulched and have siltation checks around the base. 15. All areas of disturbance must have temporary or permanent stabilization within 14 days of the initial disturbance. After this time, any disturbance in the area must be stabilized at the end of each work day. The following exceptions apply: i) Stabilization is not required if work is to continue in the area within the next 24 hours and there is no precipitation forecast for the next 24 hours. ii) 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). Land Use Permit #4C0526-12 Page 3 of 4 16. All disturbed areas of the site shall be stabilized, either seeded and mulched or covered in stone or rolled erosion control matting immediately upon completion of final grading. All disturbed areas not involved in winter construction shall be double mulched and seeded before September 15. Between the periods of October 15 to April 15, all earth disturbing work shall conform with the "Winter Construction" standards and specifications of the Vermont Standards & Specifications for Erosion Prevention & Sediment Control (2006). 17. A copy of the approved erosion control plan shall be on the site at all times during construction. 18. In addition to conformance with all erosion control conditions, the Permittee shall not cause, permit or allow the discharge of waste material into any surface waters. Compliance with the requirements of this condition does not absolve the Permittee from compliance with 10 V.S.A. (§§ 1250-1284) Chapter 47, Vermont's Water Pollution Control Law. 19. The Permittee shall maintain a 50-foot undisturbed, naturally vegetated buffer strip between all watercourses on the project site and any disturbed areas. 20. All stumps shall be disposed of on -site above the seasonal high water table or at a State approved landfill so as to prevent groundwater pollution. 21. No exterior light fixtures have been proposed or approved by this permit amendment. 22. The Permittee shall not erect exterior signage without first obtaining approval from the District Commission. Signage includes banners, flags, and other advertising displays, excepting temporary real estate marketing signs. 23. The installation and/or use of electric resistance space heat is specifically prohibited without the prior written approval of the District Environmental Commission. 24. Should the town at any time agree to accept any private utilities being then operated by the Permittee and/or assigns and successors in interest, the Permittee and/or assigns and successors in interest shall be responsible to improve the same to Town specifications and shall deed all lands involved with said improvements to the Town. Such improvements may require a land use permit amendment. 25. No further subdivision, alteration, and/or development of any parcel of land approved herein shall be permitted without the written approval of the District Commission or a written determination from the District Coordinator that a permit is not required. 26. The Permittee shall reference the requirements and conditions imposed by Land Use Permit #4C0526-12 in all deeds of conveyance and leases. 27. Pursuant to 10 V.S.A. § 6090(c) this permit amendment is hereby issued for an indefinite term, as long as there is compliance with the conditions herein. Notwithstanding any other provision herein, this permit shall expire three years from the date of issuance if the Permittee has not commenced construction and made substantial progress toward completion within the three year period in accordance with 10 V.S.A. § 6091(b). 28. All site work and construction shall be completed in accordance with the approved plans by October 30, 2012, unless an extension of this date is approved in writing by the Commission. Land Use Permit #4C0526-12 Page 4 of 4 Such requests to extend must be filed prior to the deadline and approval may be granted without public hearing. 29. The Permittee shall file a Certificate of Actual Construction Costs, on forms available from the Natural Resources Board, pursuant to 10 V.S.A. § 6083a(g) within one month after construction has been substantially completed or two years from the date of this permit, whichever shall occur first.

Upon request, the Permittee shall provide all documents or other information necessary to substantiate the certification. Pursuant to existing law, failure to file the certification or pay any supplemental fee due constitutes grounds for permit revocation.

Mr. Gallo said the position of the cabinets didn't allow access from the rear because of slope and other conditions. If any plantings are removed during access, they will be replaced. Mr. Belair said staff is OK with this. Ms. Quimby moved to approve Site Plan Application #SD-09-24 of Technology Park Partners subject to the stipulations in the draft motion. Mr. Farley seconded. Motion passed unanimously. 5. Site Plan Application #SP-09-25 of Technology Park Partners to amend a previously approved plan, site plan approval #SP-09-11, for a 111 sq. ft. utility cabinet vault and cabinet mounted on top. The amendment consists of eliminating conditions #3 and #6 of the previous approval to allow access to the cabinets to face the road, 25 Community Drive: Mr. Gallo said this is the same issue as the previous application. Ms. Quimby moved to approve Site Plan Application #SD-09-25 of Technology Park Partners subject to the stipulations in the draft motion. Mr. Farley seconded. Motion passed unanimously. 6. Site Plan Application #SP-09-26 of Harbor Heights Homeowners Association to amend a previously approved plan for 33 multi -family dwelling units in six buildings. The amendment consists of constructing a "best fix" storm water treatment system, 33 Harbor View Road: Mr. Mullin of Heindel & Noyes reviewed the history of the application. The subdivision was built in the early 1980's, and the storm water facility was not installed according to the plan. The storm water permit from the state has expired, and the Association wants to meet the "best fix" standards. The proposal will meet state standards for a one-year design storm. Mr. Belair said Tom DiPietro says the requirements are met, but he may ask for some minor changes after approval. Ms. Quimby moved to approve Site Plan Application #SP-09-26 of Harbor Heights Homeowners Association subject to the stipulations in the draft motion. Mr. Farley seconded.

Co. Phone # Phone Fax #k Fax # # of aces Re: Harbor Heights Condominiums — Response to Stormwater Comments Dear Ray: Thank you for forwarding the comments of Tom DiPietro, Stormwater Superintendent. Since our original submittal, we have made some changes to the layout of the stormwater system. Enclosed with this letter is a revised set of drawings; please refer to these when reviewing the responses to Mr. DiPietro. 1. We typically like to see a minimum SW pipe size of 15". Can that be used here? All proposed piping will be 15-inch or larger. 2. Provide an invert out elevation for the "proposed outlet structure to replace existing storm manhole". Refer to the revised Stormwater Details (sheet 3 of 3) for invert out elevation. 3. What size storm will be directed to the infiltration gallery? All runoff will be directed to the infiltration gallery. Modeling through the 100-year storm event indicate that no surcharging of existing or proposed structures will occur. 4. Please provide any results from soil investigation? Groundwater elevation? Two soil borings via hand -auger were performed on April 15. Results are as follows: HA-1 (Located 9 feet SW of outlet structure) 0 — 4": Dark brown topsoil/fine sandy loam 4 — 30": Dark orange fine sandy loam, few stones, moist @ 18" 30" — 57": Light grey very fine sandy loam, increased moisture, mottles @ 30" 57" — 69": Dark grey silt loam, standing water @ 69" Mr. Raymond Belair Re: Harbor Heights Condominiums — Response to Stormwater Comments April 16, 2009 Page 2 HA-2 (Located 57 feet west of southwest corner of building 6) 0 — 15": Dark brown fine sandy loam to very fine sandy loam 15 — 40": Light grey very fine sandy loam, moist @ 36" 40 — 55": Silt loam, standing water @ 55" 5. The detail provided for the swirl separator shows a pass through design, not a 90 degree turn as would be required by the proposed configuration. Provide an updated detail. Refer to the revised Stormwater Details (sheet 3 of 3) for a revised swirl concentrator detail. 6. How will the containment row function? A note on the detail says that there is an impermeable liner (typo?). The revised structure details clarify that a permeable filter fabric, not an impermeable liner, surrounds the containment row. The containment row's purpose is to trap sediment the swirl concentrator is unable to remove. The filter fabric prevents sediment from migrating through the rest of the structure and allows for ease of cleaning. 7. We prefer not to see steps in manhole structures. This encourages people to enter without following the appropriate safety procedures, and can become a hazard over time if the steps rot. Steps have been removed from all concrete structures. Refer to the revised Stormwater Details. We look forward to presenting this project before the Development Review Board on April 21. Sincerely, Shane M. Mullen, P.E.

(t) Proposed structures shall be related harmoniously to themselves, the terrain, and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. No changes to the existing buildings are being proposed as part of this application and therefore the aforementioned criteria are not applicable. Site plan applications shall meet the following specific standards as set forth in Section 14.07 of the South Burlington Land Development Regulations: (a) The reservation of land may be required on any lot for provision of access to abutting properties whenever such access is deemed necessary to reduce curb cuts onto an arterial of collector street, to provide additional access for emergency or other purposes, or to improve general access and circulation in the area. At this time, staff does not suggest providing additional accesses. (b) Electric, telephone and other wire -served utility lines and service connections shall be underground. Any utility installations remaining above ground shall be located so as to have a harmonious relation to neighboring properties and to the site. Pursuant to Section 15.13(E) of the Land Development Regulations, any new utility lines, services, and service modifications shall be underground. (c) All dumpsters and other facilities to handle solid waste, including compliance with any recycling or other requirements, shall be accessible, secure and properly screened with opaque fencing to ensure that trash and debris do not escape the enclosure(s). There are no changes proposed to the existing trash facilities. (d) Landscaping and Screening Requirements As there is no building construction proposed for this site, there are no minimum landscaping requirements. As the application includes the alteration of more than twenty cubic yards of fill, this application shall also be reviewed under Section 3.12 of the Land Development Regulations. The removal from land or the placing on land of fill, gravel, sand, loam, topsoil, or other similar material in an amount equal to or greater than twenty (20) cubic yards, except when incidental to or in connection with the construction of a structure on the same lot, shall require the approval of the Development Review Board. The Development Review Board may grant such approval where such modification is requested in connection with the approval of a site plan, planned unit development or subdivision plat. This section does not apply to the removal of earth products in connection with a resource extraction operation. Agenda #6 Standards and Conditions for Approval: (1) The Development Review Board shall review a request under this Section for compliance with the standards contained in this sub -Section 3.12(B). An application under Section 3.12(A) above shall include the submittal of a site plan, planned unit development or subdivision plat application showing the area to be filled or removed, and the existing grade and proposed grade created by removal or addition of material. The applicant submitted a plan showing the new pond and subsequent re -grading on the subject property. This plan is sufficient to satisfy this requirement. (2) The Development Review Board, in granting approval may impose any conditions it deems necessary, including, but not limited to, the following: (a) Duration or phasing of the permit for any length of time. Staff does not feel this requirement is applicable to the subject application (b) Submission of an acceptable plan for the rehabilitation of the site at the conclusion of the operations, including grading, seeding and planting, fencing drainage, and other appropriate measures. The applicant is proposing to install a stormwater retention structure. The South Burlington Stormwater Superintendent has been working with the applicant to review the plans and will continue to do so. Staff finds it sufficient to grant approval of this application conditional upon the satisfaction of the Stormwater Superintendent. (c) Provision of a suitable bond or other security adequate to assure compliance with the provisions of this Section. Staff does not feel this requirement will be necessary for the subject application. (d) Determination of what shall constitute pre -construction grade under Section 3.07, Height of Structures.

I Page 1 of 1 ray From: Tom Dipietro Sent: Friday, April 17, 2009 10:11 AM To: ray Subject: Harbor Heights SW review Ray, I have reviewed Shane's responses to my comments (letter dated 4/16/09) on the Harbor Heights stormwater project. They are satisfactory. As you know, when a neighborhood wants to turn a stormwater system over to the Stormwater Utility, we have an application and review process that we go through. I received the application and necessary technical information for the SW Utility review process yesterday. I will be reviewing it next week. As a result of this process it is possible that there could be some changes to the plan. Ideally, I would have received this information prior to the DRB hearing. In case the applicant comes back with changes, I thought I should mention it now. -Tom Thomas J.
