On the 81h day of December, 1998 the South Burlington Planning Commission approved the request of BDP Realty Associates for preliminary plat approval under Section 203 of the South Burlington Subdivision Regulations based on the following findings: 1. This project consists of: 1) razing a 21,200 square foot general office building, 2) constructing a 239,708 square foot addition and a 20,476 square foot connector to an existing 124,208 square foot general office building, 3) constructing a 646 space 3-level parking structure, and 4) merging three (3) lots into one (1) lot. The 124,208 square feet building was approved on 12/15/87. Several minor site modifications have been made since 1987. This application will be treated as a planned unit development. The sketch plan was reviewed on 11/10/98. 2. This property located at 1400 Shelburne Road lies within the C2 District, and the Bartlett Brook Watershed Protection Overlay District. It is bounded on the north by IDX Drive, on the west by Shelburne Road, on the east by Green Mountain Drive, and on the south by an auto dealership. 3. Access/circulation: Access is currently provided by a 32 foot and 45 foot curb cut on IDX Drive and a 24 foot curb cut on Shelburne Road. The applicant proposes to: 1) eliminate the Shelburne Road curb cut, 2) extend IDX Drive to connect with Green Mountain Drive, and 3) construct a new 24 foot curb cut on Green Mountain Drive. Circulation on the site is adequate. 4. Coverage/setbacks: Building coverage is 22.5% (maximum allowed is 30% and includes parking garage). Overall coverage is 64.8% (maximum allowed is 70%). Front yard coverage along Shelburne Road is 0%, along IDX Drive is 34.4%, and along Green Mountain Drive is 35.6% (maximum allowed is 30%). Front yard coverages along IDX Drive and Green Mountain Drive are proposed to be exceeded. The Planning Commission may allow these coverages to be exceeded under Section 12.406(b) of the zoning regulations. 5. The existing building and proposed addition will meet the setback requirements. The proposed parking structure does not meet the 40 foot front yard setback requirement from Green Mountain Drive. The proposed setback is 12 feet. The applicant sought a waiver from the front setback requirement as provided under Section 12.406(b) of the zoning regulations. Staff did not see a problem with granting this waiver. 6. ParkinQ: A total of 1538 spaces are required and 1394 spaces are provided including 26 handicapped spaces. This represents a 144 space or 9.4% shortfall. It was the applicant's position that the 29,888 square feet used for storage and the 20,476 square feet of building connector space should not be used for parking calculation. If these square footages are not included in the calculation, a total of 1337 spaces are required or 57 spaces more than required. A bike rack is provided as required under Section 26.253(b) of the zoning regulations. 7. Staff did not agree that storage space should be subtracted when calculating required parking spaces since storage is an important component of the City's office parking standard. Staff did not see a problem with subtracting out the 20,476 square feet ofbuilding connector/cafeteria space. With this area subtracted out, the required parking is 1456 spaces which represents a 62 space, or 4.3%, waiver. Staff did not see a problem with approving this number of spaces since the Commission has routinely granted up to an 8% parking waiver for multiple story office buildings. 8. The parking count information on the cover sheet should be revised to correct the square footage of office space and the number of spaces required. Parking is based on gross square footage/250 (384,329 square feet/250 = 1538 spaces). 9. Parking structure: The proposed parking structure does not appear to meet the "Design Guidelines for Parking Structures" in the following manner: the maximum distance between parking spaces and nearest exit stairwell is greater than 200 feet (i.e., 240 feet). — there should be two (2) elevators for up to 500 parking spaces and no elevators proposed. — lighting information within the structure was not provided. Staff was unable to determine whether adequate lighting is proposed to meet the guideline. 10. Landscaping: The minimum landscaping requirement, based on building costs, is $257,950 which is being met. Proposed plantings include: Red Maple, Green Ash, Crabapple, Honeylocust, Sugar Maple, Birch, Pin Oak, Shadblow, Spruce, Pine, Viburnum, Juniper, and Wintercreeper. Landscaping plan should be revised to provide street trees on the east side of the extended portion of Green Mountain Drive. 11. Staff recommended that parking be shifted back to create a green strip between the circulation aisle and parking and the proposed r.o.w. (at the northwest corner of the site) and that this green strip be adequately landscaped. 12. Bartlett Brook Watershed Protection Overlay District BBW): This property is located in the BBW District. Under Section 23.20 of the zoning regulations, the applicant shall submit applicable information regarding the development and storm water management design to Heindel and Noyes for inclusion into the City's stormwater hydrology computer model. The final plat plans should incorporate the recommendations from Heindel and Noyes. 2 13. Building height: Section 25.113(a) of the zoning regulations limits the height of a flat roof structure to 35 feet. The proposed addition will have a height of 68 feet from the average pre - construction grade. This is 33 feet greater than permitted. Section 25.113(c) of the zoning regulations allows the Planning Commission to approve a non-residential structure with a height in excess of the limitations provided the Commission determines that a taller structure: (i)) will not affect adversely the essential character of the neighborhood or district in which the property is located. (ii) will not detract from important scenic views from adjacent public roadways and other Public rights -of -way. 14. Section 25.113(d) of the zoning regulations requires additional front, side and rear setbacks for taller structures. The proposed addition will meet the additional setback requirements. 15. Information on the height of the parking structure measured to top of the light fixtures on the upper level should be provided. 16. Sewer: The additional sewer allocation requested is 24,588 gpd (this includes 20% reduction allowed by State). The applicant will be required to pay the per gallon fee prior to permit issuance. There is currently no reserve capacity currently available at the Bartlett Bay Wastewater Treatment Facility. Approved allocation will be placed on a waiting list until such time as allocation is available. The Commission's policy has been that a permit can not be issued until allocation is available. Allocation is projected to be available at the end of July, 1999. Staff did not see a problem with amending the policy as long as the new space is not occupied until the new plant expansion is on line. 17. Traffic: The applicant submitted a traffic impact study addressing the impact of the proposed addition. This report has been submitted to the MPO for their review and comment. The study concludes as follows: Overall levels of service during the AM and PM peak hour north of IDX are acceptable with the IDX expansion in 2005. IDX Drive/US 7 operates poorly during the no -build and build scenarios by 2000. South of IDX Drive, certain intersections begin to show poor levels of service by 2005, including the Bartlett Bay Road approach to US 7, the US 7/Allen Road and US 7 Pine Haven Road intersections, and the Bay Road approach to US 7. 18. To mitigate the above impacts, the study recommended the following: 1) With the expansion of IDX to over 300 employees, a left -turn lane should be constructed on southbound US 7 at IDX Drive, and a right turn signal should be added to the westbound approach to service IDX Drive. 2) Intersections south of IDX Drive will significantly improve levels of congestion with the construction of the VAOT Shelburne Road improvements. At this time, they do not recommend any additional mitigation for those affected intersections beyond what will be constructed by VAOT. 3) IDX should continue their transportation demand management program that includes flex- time and support of alternative transportation modes. If is does not already, the program could include a clearinghouse for van pool/car pool information for employees. The company can also provide secure bicycle facilities and showers for those wishing to walk or bike to work. 4) Traffic signal offsets and timings should be maintained in the corridor to improve coordination between signals. 19. Staff recommended that the applicant conduct a signal timing/coordination analysis for the corridor. Also, a queue length analysis should be conducted, in particular, the southbound left -turn queque at IDX Drive. 20. Section 12.403(a) of the zoning regulations requires an overall intersection LOS of "D" or better. In addition, the individual LOS for thru movements on the major roadway shall be "D" or better. There are several intersections and thru movements that will not meet the standards of this section. 21. The applicant should be aware that the road impact fee is approximately $110,000. 22. Dumpsters: The dumpsters will be located inside the building. 23. Lighting: Proposed exterior lighting consists of the following: twelve (12) 100 watt metal halide lamps mounted on 43" bollards. — nine (9) 27 watt flourescent lamps mounted on the building with downcasting shielded fixtures. thirteen (13) 100 watt halogen stake -mounted uplights. three (3) 100 watt halogen surface -mounted uplights. — forty-four (44) 175 watt metal halide lamps mounted on 20 foot poles with downcasting shielded fixtures. eleven (11) fountain lights. Existing exterior lights consist of the following: 4 nine (9) 250 - 400 watt metal halide lamps with downcasting shielded fixtures. 24. Lot merger: A lot merger agreement, approved by the City Attorney, should be recorded prior to recording the final plat plans which merges lots A, B and the recently acquired lot #11 from Allson Partnership. 25. Other: the two (2) survey plats should be combined into one (1) plat showing the entire property. The property lines to be dissolve should be noted as such. A lot merger agreement will not be needed if this is done. — the site plan should show the zoning boundaries. — applicant should research whether the legal documents are in place to extend IDX Drive and Green Mountain Drive and make the connection. — the landscape plan does not accurately show the r.o.w. taking at the northwest corner of the site. DECISION & CONDITIONS Based on the above Findings of Fact, the South Burlington Planning Commission approves the preliminary plat application of BDP Realty Associates for a planned unit development consisting of 1) razing a 21,200 square foot general office building, 2) constructing a 239,708 square foot addition and a 20,476 square foot connector to an existing 124,208 square foot general office building, 3) constructing a 646 space 3-level parking structure, and 4) merging three (3) lots into one (1) lot, as depicted on a 19 page set of plans, page four (4) entitled, "IDX South Burlington Vermont Master Site Plan," prepared by Trudell Consulting Engineers, Inc, et al, dated 11/12/98, with the following stipulations: 1) All previous approvals and stipulations which are not superseded by this approval shall remain in effect. 2) Prior to issuance of zoning permit for the first phase or start of utility or road construction, all appropriate legal documents including easements (e.g., irrevocable offer of dedication and warranty deed for the proposed public road extension and utility, sewer, drainage and water, etc.) shall be submitted to the City Attorney for approval and recorded in the South Burlington land records. 3) Prior to start of construction of the improvements described in condition #2 above, the applicant shall post a bond which covers the cost of said improvements. 4) In accordance with Section 301.5 of the subdivision regulations, within 14 days of completion of required improvements (e.g., roads, water mains, sanitary sewers, storm drains, etc.) the developer shall submit to the City Engineer, "as -built" construction drawings certified by a registered engineer. 5) Pursuant to Section 12.406(b) of the zoning regulations, the Planning Commission modifies the front yard coverage limitations to be exceeded along Green Mountain Drive and IDX Drive. 6) Pursuant to Section 26.406(b) of the zoning regulations, the Planning Commission modifies the front yard setback requirement along Green Mountain Drive to allow the proposed parking structure to be within 12 feet of the front property line. 7) Pursuant to Section 26.256(b) ofthe zoning regulations, the Planning Commission approves atotal of 1394 spaces which represents a 62 space or 4.3% waiver.
