/FO ft I O'Leary -Burke Civil Associates, PLC CIVIL ENGINEERING I REGULATORY AND PERMIT PREPARATION I LAND SURVEYING I CONSTRUCTION SERVICES I LAND USE PLANNING April 16, 2018 Mr. Ray Belair, Zoning Administrator South Burlington Planning and Zoning 575 Dorset Street South Burlington, VT 05403 RE: Administrative Site Plan Review of Record Drawing (SP#16-10) Lots 19, 20, 21- Ethan Allen Commercial Park 6 Ethan Allen Drive, South Burlington, Vermont Dear Mr. Belair: As requested O'Leary -Burke Civil Associates is writing on behalf of Allen Brook Development c/o Al Senecal to request after the fact site plan approval for minor 'as built' changes to the approved, and recently constructed, 39,535 sf +/- commercial building located at 6 Ethan Allen Drive in South Burlington. We understand that you inspected the site on November 15t", 2017 and noted that the 'as built' locations of some of the site improvement were slightly different than approved and that those changes would require an administrative site plan amendment. The attached plan was updated on April 6, 2018 to reflect the following changes: 1. Interior Space: Originally the building was approved as two units, with unit #1 being 15,000 sq. ft. and unit #2 being 24,535 sq. ft. A Zoning permit issued in August 2017 approved unit #2 to be subdivided into three smaller units, the enclosed record drawing reflects that change and shows how the building has been divided into four units. 2. As built parking lot striping: During construction an additional handicapped parking space was added along the buildings southern face, this decreased the total number of parking space onsite from 41 to 40, 36 parking spaces are required. The enclosed record drawing includes updated parking requirements and shows the as built locations of all parking. 3. As built locations of all sidewalks: During construction a short 22- ft section of sidewalk was added to provide handicapped access to unit #3. 13 CORPORATE DRIVE ESSEX JUNCTION VERMONT 05452 TEL 802 878 9990 1 FAX 802 878 9989 1 obca@olearyburke.com 4. As built locations of the HVAC units: Two HVAC units were approved but were relocated during construction. The HVAC units were approved with screening by small and mid size shrubs which have been planted. 5. As built locations of all landscaping: An updated landscape schedule, showing the as built locations and quantities, has been added to the enclosed record drawing. Per the buildings original 2016 approval a total landscaping budget of $27,000 was required, a budget of $28,625 was proposed, and based on the as built landscaping quantities a total of $28,375 has been planted thus remaining over the minimum amount of landscaping required. 6. As built locations of dumpsters: Four dumpsters located inside the NE outdoor storage yard have been added, screening from the road has been provided by the storage yards' privacy fence. 7. As built location of free standing sign: A freestanding sign for the building was approved in April 2017 the location of the freestanding sign has been added to the enclosed record drawing. Attached please find an application for Administrative Site Plan review with application fee of $223.00 ($140.00 x 1.50 after the fact fee + $13 recording fee), three (3) full size, one (1) reduced, and one (1) digital copy of the plan sheet RD '50-Scale Site Plan, Record Drawing'.

Project Description The project is to construct a 50,150 5F +/- commercial building with associated parking on undeveloped lots 19, 20, 21 of the Ethan Allen Commercial Park totaling 7.3 acres. The project is located at 6 Ethan Allen Drive across from the three way intersection with Ethan Allen Drive, Shamrock Road, and Airport Parkway/Lime Kiln Road. The topography of the site consists of a flat area located along Lime Kiln Road then drops 20-25 feet to a flat area located at the top of the bank to a tributary of the Winooski River. A Class II wetland associated with the tributary was delineated on the southern end of the site. 2. Receiving Water The building and parking lot stormwater runoff is treated by the proposed infiltration trench and wet pond that discharge to the Winooski River. 13 CORPORATE DRIVE ESSEX JUNCTION VERMONT 05,152 TEL 80 878 7990 1 FAX 802 8i8 9989 I obca@olearyhurke.x (M) Page 2of6 3. Existing Conditions The drainage area for the project is made up of three different types of HSG soil groups. The drainage area of the site is made up of AgA - Agawam fine sandy loam 0-5% slopes (HSG A), Wo - Winooski very fine sandy loam (H5G C) and MyB - Munson and Raynham silt looms 2-6% slopes (HSG 0). The site contains a 100-year base flood elevation at 217' and a river corridor boundary. 4. Existing Stormwater System The site is 7.3 acres and undeveloped. The majority of the site has no impervious area except for a small graveled turnaround on the western end of the site. The site does not have an existing stormwater discharge permit. 5. Proposed Stormwater System The proposed Stormwater system consists of two discharge points. The first is an infiltration trench located behind the proposed building on the north western end of the site. The trench has been designed to contain the water quality storm for the 50,150 SF of rooftop runoff. The roof leaders are being directly connected to the underground infiltration trench. Since the building is being built into the bank on Lime Kiln Road the soil borings being conducted for the building site will be used to confirm three feet of separation between the bottom of the trench and groundwater levels. The Swale has been placed mostly within the on -site H5G class A soil group. The primary purpose for the Swale is to meet the groundwater recharge requirement and reduce phosphorus discharge. The infiltration trench has also been designed with an overflow system to the detention pond. The second discharge point being used to treat the stormwater runof f is a wet pond located on the north eastern corner of the site. The wet pond is designed to treat the runoff from the paved parking lot, graveled outdoor storage areas, and all rooftop runoff greater than the WQv storm event. The wet pond has also been designed with a forebay and permanent pool. The outlet structure discharges to a wetland directly associated with the Winooski River. The following information summarizes the project: A. Point of Interest #1 Drainage Area: 2.68 acres (1.89 ac. impervious) Point of Interest #2 Drainage Area: 1.76 acres (1.18 ac. impervious) B. The receiving water is the Winooski River; Page 3of 6 C. Based on review of Appendix A of the Vermont Water Quality Standards (VWQS), no stream large enough to support fish habitat leaves the site and is not listed on the warm water list, therefore the project was modeled as a cold water habitat; D. Two discharge points are shown on the plans; E. Demonstrate Compliance with each of the criteria: Water Quality Treatment Standard POI #1 - The Water Quality standard is met by using a (P-3) wet pond with at least 50% of the water quality volume provided below the permanent pool. Calculated Water Quality Volume (WQv) = 5,966 ft3 50% Water Quality Volume (WQv) = 2,983 ft3 Water Quality Volume Provided in Permanent Pool of Wet Pond = 2,983 ft3 Permanent Pond Elevation = 214.4 ft POI #2 - The Water Quality standard is met using the infiltration trench. The trench has been design to store and infiltration the entire WQv storm event in 48 hours. The equation on page 2-39 of the VSMM Treatment Standards was used to ensure that the design system has the required bottom surface to infiltrate the entire WQv storm event. AP = VW / (n * dt + fc * T/12) Where: AP - surface area, ft2 VW - design volume, 3,757 ft3 n - porosity, assumed to be 40% dt - trench depth, 4.1 ft fc - infiltration rate, assumed to be 0.5 inches per hour T - time to fill trench, assumed to be 2 hours AP = 2,180 SF required Proposed 4 ft wide trench with 2,270 5F of bottom surface area Page 4 of 6 ii. Groundwater Recharge Treatment Standard The recharge requirement is met using the percent area method by the rooftop runoff and the infiltration trench. The site is required to recharge 13,072 5F of impervious coverage during the WQv storm event. We are proposing to recharge the entire rooftop runoff of the 50,150 5F building during the WQv storm event via the infiltration trench. We have designed the trench to store and infiltrate the entire WQv rooftop runoff in order to get credit for 90% phosphorus removal. iii. Channel Protection Standard (1-year} The channel protection volume is met for the entire site in POI #1 by the storage and outlet structure in the wet pond. The infintration trench is equipped with an overflow system that discharges into the wet pond during the 1-year storm event. The cold water habitat of the Winooski River dictates a target center of mass detention time criteria is 720min. The center of mass detention time is being met as closely as possible using the low flow orifices on the outlet structure. The following summary is derived from the HydroCAD model: Point of Interest #1 Predevelopment Flow POI #1 1.56 cfs Post Development Flow POI #1 9.39 cfs Routed Post Development POI #1 0.83 cfs Center of Mass Detention Time 725.9 min iv. Overbank Flood Protection Standard (10-year) The overbank flood protection standard is met for the entire site in POI #1 by the storage and outlet structure in the wet pond. The infintration trench is equipped with an overflow system that discharges into the wet pond during the 1-year storm event. The following summary is derived from the HydroCAD model: Point of Interest #1 Predevelopment Flow POI #1 4.41 cfs Post Development Flow POI #1 15.24 cfs Routed Post Development POI #1 4.17 cfs Page 5 of 6 V. Extreme Flood Protection Standard (QP100) The extreme flood protection standard is waived for this project since the new impervious coverage is less than 10 acres. F. Manner of Discharge: S/N 001: Stormwater runoff from the parking lot and building via a catch basin network flows to the on -site wet pond discharging to a wetland associated with the Winooski River. S/N 002: Stormwater runoff from the building rooftop via a pipe network flows into an infiltration trench that discharges to groundwater which flows to the Winooski River for the water quality storm event and runoff from all larger Stormwater events is diverted to S/N 001 which discharges into a wetland associated with the Winooski River G. Phosphorus Removal: The stormwater design utilizes an infiltration trench within mostly HSG class A soils to store and infiltrate the entire WQv storm event for the rooftop runoff. By infiltrating all of the rooftop runoff associated with the WQv storm event 90% of the phosphorus load is being treated. The remaining impervious area is piped to a wet pond located within HSG class() soils that are not ideal for infiltration. The standard wet pond practice has a phosphorus removal rate of 40%. Weighted average phosphorus removal rate: Infiltration trench impervious area = 1.18 acres Wet pond impervious area = 1.89 acres Total impervious area = 3.07 acres (1.18/3.07)(0.90) + (1.89/3.07)(.40) = 60% removal rate ii. Offset project: The simple method pollutant loading calculation worksheet shows the project will require 3lbs of phosphorus to be offset.

The revised layout is in response to a 20' easement across lot 21 to the Town of Colchester for an existing forcemain. The building has been reduced by 10,620 SF in order to not encroach on the easement. The project has been continued by the DRB to the May 17th meeting and was last heard at the March 15th meeting. The proposal is still to combine the three (3) commercial lots to create a 7.6- acre parcel and construct the new 39,535 SF commercial building located in the Mixed Industrial and Commercial (IC) Zoning District. The intent is to split and lease the building into two (2) units. Unit #1 will have 2,000 SF of retail warehouse outlet space and 13,000 SF of warehouse space. Unit #2 will have 2,000 SF of retail warehouse outlet space and 22,535 SF of warehouse space. The building will be served by municipal water and sewer connections from Ethan Allen Drive. The building will have a maximum of 20 employees at any one time and will require 240 gpd of sewer allocation and 270 gpd of water allocation. The reduction in building size will reduce the amount of PM peak trips produced by the project. The reduced 39,535 SF building is estimated to have 79 average weekday trips and 8 PM peak hour trips. The original traffic impact assessment completed for the 50,155 SF building by Roger Dickinson of Lamoureux & Dickinson concluded that the project would not create an adverse impact on future traffic congestion or safety conditions. Since the amount of PM peak trips are being reduced, the same conclusion is valid. The 13 CORPORATE DRIVE ESSEX JUNCTION VERMONT 05452 TEL 802 878 9990 1 FAX 802 878 9989 1 obca@olearyburke.com project should contribute 8,000 ($1,000 per PM peak hour trip) to the City's Road Impact Fee program to help fund future improvements at Airport Parkway/Ethan Allen Drive and other intersections.

The new system proposes two underground infiltration areas sized to infiltrate the water quality storm event on -site. An ADS water quality unit has been provided to pre -treat the runoff from the parking and storage areas before infiltration. A dry detention pond with an outlet structure is still being proposed on the north east corner of the site to provide enough storage to meet the 25-year standard. The total impervious coverage on the site has been reduced by 0.45 acres down to 2.62 acres. Attached please find the following information for your review: 1. Five (5) full size, one (1) reduced set of project plans; 2. Memo to Ray Belair addressing all red items in the staff report dated 3/11/16 from the continued DRB hearing and the Fire Marshals comments dated 4/7/16.

The elevations for the building still indicate there will be three tenants, for example in the drawing of the west elevation there are signs for Tenant 1, Tenant 2, and Tenant 3. The Landscape Plan shows five honeylocust in the vicinity of eight isolated parking spaces on the eastern side of the building; however, the numbering on the plan (in parentheses) indicates there are eight in that area. Just to prevent any confusion it might be helpful to update those plan sheets prior to the Board reviewing them.

The proposed project is located in the Winooski River watershed and discharges to a class 2 wetland. The VSWI Advisory Layer on the Agency of Natural Resources' online Wetlands Inventory Map shows additional wetlands that are not depicted on the submittal sketch. In a future application, the wetland delineation report developed by Natural Resources Consulting Services dated April, 2015 should be submitted along with the site plan for review. Please see attached for the wetland delineation report from Natural Recourses Consulting Services. The project proposes to create an additional 133,482 square feet of impervious area on the parcel. This will result in greater than 1 total acre of impervious area on the parcel. Therefore, the project will require a stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. A State stormwater discharge permit has been applied for and its approval is pending. The project proposes to disturb greather than 1 acre of area. It will therefore require a construction stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. A State moderate risk construction general permit has been applied for and its approval is pending. 4. As the site plan proposes more than 0.5 acres of impervious surface, the applicant will need to meet the requirements of 12.03 of the City's Land Development Regulations, as approved by the Planning Commission on November 10, 2015. These requirements include infiltration of the WQv on site using Low Impact Development (LID) practices in lieu of a stormwater detention pond. Stormwater ponds will only be approved if the applicant can demonstrate that it is unfeasible to infiltrate the volume of stormwater runoff specified in 12.03 (C)(1). Additional requirements listed in the LDRs included, but are not limited to, controlling the post construction peak runoff rate for the 1-yr, 24-hr rain event as to not exceed the existing peak runoff rate for the same storm event. A stone infiltration trench, behind the proposed building, has been designed to infiltrate the entire WQv storm for the building's rooftop runoff. A new underground storage system has been proposed just before the detention pond to collect the WQv runoff from the remaining impervious coverage, see attached Sheet 1— Site Plan. The underground system overflows to the detention pond at any storm event greater than the WQv storm, see HydroCAD model. For this analysis I used a conservative infiltration rate of 0.5 inches per hour for both the trench and stormtech systems. 5. Design of retaining wall adjacent to stormwater detention pond forebay precludes vehicle access for maintenance of forebay and outlet structure. The north east corner of the outdoor storage space was lowered and graded down to the pond on a 1 on 3 slope. The northern end of the wall has been rotated 90 degrees for better access. 6. It appears that the infiltration trench is served by a 24" underdrain. Cleanouts or access points should be indicated for the underdrain. The roof drain infiltration trench detail on Sheet S2 — Stormwater Details has been revised. The yards drains will be installed with drop in grates so they can be used as cleanouts. The spacing of the yard drains / cleanouts will be at every roof leader connection or a min of 100 ft. The yard drains will be connected directly to the 24" PE pipe instead of being run to the bottom of the stone trench. 7. Provide any soil boring information available in the vicinity of the infiltration trench system. Soil borings were completed for the site but we are still waiting for the results to come back. We are hoping to have the results back by the end of the day Friday. Four 6 foot deep test pits were dug around the 230' contour on the bank to get an idea of the soil characteristics at the elevation of the infiltration trench system. There were no groundwater issues and an infiltration rate of 1.3 minutes / inch was calculated. 8. The applicant is requested to provide a copy of the stormwater modeling submitted to VT DEC in a digital format. Please see attached for the revised HydroCAD model. 9. Work in the City Right Of Way (ROW) requires a permit before construction can begin. A "Permit to Open Streets or Right -Of -Way" can be obtained from the South Burlington Department of Public Works on their web site, or by stopping by their office located at 104 Landfill Road. Since this permit is only good for 30 days, we request that a condition of approval be included stating a "Permit to Open Streets or Right -Of -Way" shall be obtained prior to the start of construction. 10. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. No problem. Let me know if you have any additional questions.

A new underground storage system has been proposed just before the detention pond to collect the WQv runoff from the remaining impervious coverage, see attached Sheet 1— Site Plan. The underground system overflows to the detention pond at any storm event greater than the WQv storm, see HydroCAD model. For this analysis I used a conservative infiltration rate of 0.5 inches per hour for both the trench and stormtech systems. 4.(a) In reviewing the HydroCAD modeling, it appears that the site would be more accurately represented by using a "weighted-Q' runoff calculation than a "weighted-CN" runoff calculation. As noted on Hydrocad's website "composite CN values should be used only for interspersed runoff areas that cannot accurately be divided into independent sub -areas." While the 17,000 sq. ft. Outdoor Storage area is arguably part of an interspersed runoff area, the majority of the impervious surface in the "Site" subcatchment discharges directly to a catch basin and into the underground infiltration system. The model and design should be adjusted to infiltrate the entire runoff volume generated by the impervious surface during the WQ storm event, as required by the City's LDRs. This might be simply accomplished by modifying the infiltration rate to more accurately represent the actual infiltration rate of the system, if the soil boring results permit. 4.(b) The Storm System Maintenance notes on Sheet S2 should include discussion of removal of sediment from catch basins, underdrains, pond forebay and outlet structure. 4.(c) The Roof Drain Infiltration Trench detail on Sheet S2 should be revised to more clearly depict relative dimensions. 4.(d) Trash Rack detail on Sheet S2 — Where is this utilized in the project? 5. Design of retaining wall adjacent to stormwater detention pond forebay precludes vehicle access for maintenance of forebay and outlet structure. The north east corner of the outdoor storage space was lowered and graded down to the pond on a 1 on 3 slope. The northern end of the wall has been rotated 90 degrees for better access. The proposed grade and turning radius of the embankment still prohibit accessing the entire forebay in order to excavate accumulated sediment and load it into a truck. 6. It appears that the infiltration trench is served by a 24" underdrain. Cleanouts or access points should be indicated for the underdrain. The roof drain infiltration trench detail on Sheet S2 — Stormwater Details has been revised. The yards drains will be installed with drop in grates so they can be used as cleanouts. The spacing of the yard drains / cleanouts will be at every roof leader connection or a min of 100 ft. The yard drains will be connected directly to the 24" PE pipe instead of being run to the bottom of the stone trench. The proposed 6" cleanouts do not seem adequate for maintenance of a 550'+ run of 24" pipe. Consider catch basin access points at the upstream point of the underdrain system and the bend at the corner of the building. Provide any soil boring information available in the vicinity of the infiltration trench system. Soil borings were completed for the site but we are still waiting for the results to come back. We are hoping to have the results back by the end of the day Friday. Four 6 foot deep test pits were dug around the 230' contour on the bank to get an idea of the soil characteristics at the elevation of the infiltration trench system. There were no groundwater issues and an infiltration rate of 1.3 minutes / inch was calculated. Submit soil boring results once available.

Influence of For example: The river provides flood water to the wetland in the spring. hydrology on Seasonal surface flow from the wetlands on the side of the the ravine. The wetland complex stream in the bottom of the ravine is perennial, most of the flow is from undetained flow from up -gradient development. There is an eroded channel for flow. 7.4.3. Relation to the Distance between the project area and any nearby surface waters. project area The nearest water is the Winooski River, about 0.25 mile down -grade. 7.4.4. Hydroperiod Discuss frequency and duration of flooding, ponding, and/or soil saturation. The slope of the drainage is approx. 5% and the stream flow is perennial, so the ravine stays permanently saturated. There is historic sign of beavers, but they ma eventually colonize the system to dam or slow water. 7.5. Surrounding Landuse of For example: rural residential and forested; agricultural and undeveloped, the Wetland Complex Fbodplain and agricultural land surround the site to the north. Elsewhere there are scattered single family residences, and intense commercial development nearby. 7.6.

With that said Peter, Bryan Currier and I are concerned that there may be too much distance been the outlet, rip rap and edge of wetland. Because the edge of wetland is essentially the toe of slope and where we are discharging is still quite steep. The last thing we want to have happen is an eroded outfall pipe and sediment end up washing into the wetland. Can you take a quick look at the attached plan and let us know what you think. If you would support us continuing the pipe to the bottom of bank we think we'd have a more permanent solution and even though there would be slightly more temporary disturbance to the wetland buffer, long term we think it would be best for the buffer. Bryan added notes on how to revegetate the buffer post construction. Let us know your thoughts after having looked at the attached two drawings. We are also open to any other ideas you may have.

Wetlands site visit summary letter for 6 Ethan Allan Drive, South 8urlingtoe Hi Pete and Brian, The following is a site visit summary for 6 Ethan Allen Drive in South Burlington: Please be advised there is a Class II wetland on you're the property located at 6 Ethan Allen Drive, South Burlington. This determination is based on a site visit conducted on 11/19/2015, made by Tina Heath, accompanied by Peter Spear and Brian Bertsch. PRESUMPTION OF SIGNIFICANCE: The subject wetland is contiguous to an area identified as a palustrine wetland on the Vermont Significant Wetlands Inventory maps and is therefore designated as a Class II wetland in the Vermont Wetland Rules. The Secretary has determined based on an evaluation of the functions and values of the subject wetland that it is a significant wetland and is therefore designated as a Class II wetland. At minimum, the subject wetland provides the following functions: water storage for flood water and storm runoff (VWR § 5.1), surface and groundwater protection (VWR § 5.2), fish habitat (VWR § 5.3), and erosion control through binding and stabilizing the soil (VWR § 5.10). Class II wetlands are protected under the Vermont Wetland Rules (VWR). Any activity that is not an allowed use designated in Section 6 of the VWR will require a State Wetland Permit. In addition, the U.S. Army Corps of Engineers (Corps) regulates discharge of dredge and fill material and mechanized land clearing in wetlands. For detailed information on Corps permits and regulations call (802)872-2893. In addition, your town may have local regulations regarding wetland protection. DELINEATION: I have reviewed the delineation for which has been accepted based on a field review. This delineation has been accepted on 11/19/2015. Please note that due to the dynamic nature of wetlands, delineations are valid for five years. After five years the delineation will need to be reviewed and updated. PROJECT: The following project is proposed: Stormwater outlet pipe in association with a stormwater management system for a commercial building. A Vermont Wetland Permit will be required for the propose buffer impacts. For tracking purposes, your project has been assigned to wetland project number 2015-683. Please reference this number when you submit your application. There appear to be opportunities for further avoidance and minimization. We request that you address the following in your project design before sending in a permit application: • Please review the idea of shortening the outlet pipe so that the exit is further away from the wetland boundary, providing more buffer before the water enters the wetland. We discussed the idea of shortening the pipe, and adding some riprap at the outlet. • Please send a site plan that shows the cross section and details of the outlet pipe, as discussed in the field. If you have any questions, please contact me.

O'Leary -Burke Civil Associates, PLC CIVIL ENGINEERING I REGULATORY AND PERMIT PREPARATION I LAND SURVEYING I CONSTRUCTION SERVICES I LAND USE PLANNING April 28, 2016 Mr. Ray Belair, Administrative Officer South Burlington Planning and Zoning 575 Dorset Street South Burlington, VT 05403 RE: Lots 19, 20 & 21 Ethan Allen Commercial Park, 6 Ethan Allen Drive Site Plan Application Dear Mr. Belair: We are writing on behalf of Allenbrook Development, c/o Al Senecal, to submit revised plans addressing comments raised by staff in advance of the upcoming May 17th Development Review Board meeting. The project was first presented and continued by the DRB on March 15tn Questions and Comments are italicized below and our responses follow each question. Staff Report Dated 3/11/16, Ray Belair/Paul Connor: 1. Staff recommends the Board discuss with the applicant the choice of window size and the ability of windows that size to provide a visual break to the building. Response: The peak shown on the western elevation has been centered on the windows and the slope of the peak has been increased to a 1 on 4. Please see SH A602 - Landscaped Building Elevations. 2. Staff recommends the Board discuss with the applicant the possibility of adding visual interest to the northwest corner of the building, which is visible from Lime Kiln Road. Response: Since the building has been reduced by 10,620 SF much of the existing vegetation on the north western corner of the site will be saved. The previous layout proposed to clear all the way to the northern property line and re -plant conifers on the downslope to the building. The new layout will leave some of the existing mature trees at road grade to immediately screen the corner of the building as cars travel south on Lime Kiln road. The green stripe along the western side of the building will also be extended along the angled corner facing Lime Kiln road. Please see SH 1 - Site Plan and SH A602 - Landscaped Building Elevations. 13 CORPORATE DRIVE ESSEX JUNCTION VERMONT 05452 TEL 802 878 9990 1 FAX 802 878 9989 1 obca@olearyburke.com 3. Staff recommends the Board speak with the applicant about their plans for waste disposal and the regulations outlined above. Response: The dumpster has been relocated in between the entrance and the outside storage area. Screening for the dumpster will be provided by a green pre -woven privacy fence. Please see SH 1 - Site Plan and SH 5 - Roadway Details. 4. Tree Staff recommends the Board request the applicant increase their landscaping budget. Response: The reduction of building size has lowered the project budget to $1,950,000; therefore the minimum landscaping budget has also been reduced to $27,000. We are proposing a landscaping budget of $28,625.00. First $250,000 x 3% _ $7,500 Next $250,000 x 2% _ $5,000 Balance over $500,000 ($1,450,000) x 1% _ $14,500 Total = $27,000 Please see SH 3 - Landscaping Plan 5. Staff recommends the Board discuss with the applicant the variety, number, and location trees in relation to the Landscaping and Screening Requirements, which reads in part: 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. Response: The new building layout will require 41 parking spaces; therefore 9 Honeylocust trees have been proposed as shade trees. Please see SH 3 - Landscaping Plan. 6. Staff recommends the Board support the comments provided by the Stormwater Section and include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. Response: No response required. 7. Staff recommends the Board discuss with the applicant the anticipated uses of the building and how the site will comply with Appendix A. Performance Standards of the LDRs in particular with regards to Az. Vibration, A.3 Noise, and A.4 Air Pollution. Response: These items were addressed in detail at the March 151n DRB meeting without any negative feedback. Comments from the Fire Marshal dated 4/7/16, Terry Francis: 1. Parking areas shall be configured to allow fire department suppression and aerial access to the building. Occupancy shall have monitored fire alarm system, a sprinkler/standpipe system and a fire hydrant located within 100' of the FDC. Coordinate fire protection features with SBFD. Response: In our opinion, the parking configuration will not deny suppression or aerial access to the building. The building will be equipped will all of the required fire prevention systems required by the Division of Fire Safety including a monitored fire alarm system and a sprinkler/standpipe system. The existing hydrant along Ethan Allen road at the project entrance is proposed to be relocated 160' north up Ethan Allen Drive in order to be 100' from the building. If you have any questions or require any additional information please do not hesitate to call, (802) 878-9990. Sincerely, 7 Bryan Currier, P.E.

Again this is not new and has been an ongoing problem between me and the planning and zoning and any business creating field road dust and sediment and blowing over onto my property and inside my home! And creating a serious health problem for me! Again the problem is the same! If there is going to be Construction, Ground Dust that will carry over onto my property, mainly leaving ground dirt dust sediment, along with construction dust on my home, and motor vehicles. This has been shown to happen and proven to South Burlington Planning and Zoning in the past 4yrs as vehicles travel over that field and dirt entrance and parking area's this creates dust and with minimal wind a large dust bowl develops and comes across the road leaving dust and sediment all over my motor vehicles, Plus after a short period of time depending on the amount of traffic coming and going ends up covering my home with sediment from the dust! Plus if my windows are open the dust and sediment comes into my house.. Another health issue. Gravel, Ground dirt dust, Unpaved road dust and sediment from such when airborne is a documented legal form of toxic air pollution according to United States Environmental Protection Agency and Vermont Air Quality & Climate Division, Montpelier Vt I recently asked Ray Belair last week in an email that we all sit down and have a meeting prior to the upcoming town meeting 3-15-2016 to resolve these ongoing environmental issues, The dust and sediment problems coming from that property directly across the street. But no attempts were made prior. As a disabled veteran, Allergic to Dust all my life! And now I have this serious COPD lung and breathing problems within the last 4 or 5 years! I have also been in and out of the VA hospital for this in recent years. Since yesterday March 14, at 1:30PM while I was at the Burlington VA medical clinic I was taken away by ambulance to the University of Vt Medical Center for once again unable to breath properly! COPD and some nasty virus infection going around that has affected my ability to breath. Any environmental pollution such as construction dust, road, field dust coming onto my property and into my home can cause me a lung infection! I have attached yesterday's March 14, 2016 UVM Medical Ctr patient discharge papers /_instructions should South, Burlington Planning and Zoning not take my medical condition seriously. I also have plenty of va doctor medical records showing I have this lung breathing problem. I am for the second time forewarning everyone involved about my health condition and should no environmental protection be given to me or my property and this construction building project commence I will have no options but ask that all construction cease either through a state of Vt agency or Vt court system. Again from day one Mr Al Senecal telephone no# 802-338-0911 on March 3, 2016 at 7:17PM called and I advised him of the only main issue! Dust and Sediment coming onto my property and his only solution was I only had 1 year to deal with it! Completely unacceptable and no solution or concern for the environment. March 9t" in a quick email I ask Ray we should all sit down and try to resolve this out ahead of time and nothing was ever done! This shows no consideration to the home owners near bye. I had a petition as all neighbors are concerned as of the dust and sediment coming onto their property and houses, But I have been ill and in the hospital and was not able to help them or get there signatures. They are concerned about dust and sediment all over the vehicles and houses and clean up cost. My questions are; Will there be a Filter Fabric placed high enough and surround the construction building project to contain all the dirt, dust sediment from crossing over onto my property? Or what course of action will be taken? Will there be adequate funding set aside for any clean up required resulting from construction dust, ground dirt dust sediment coming onto my home and homes nearby as many have recently had new siding and windows, My home was just washed last late fall and repainted!. Will there be weekly or as needed funding if we find construction dust, ground dirt dust sediment all over our motor vehicles? Or for other unknown conditions? Will that parking lot pull off in front next to the main road of Lime Kiln be removed as it's a common place for vehicles to pull off and as they leave a dust bowl is created and it travels across the road towards our homes. The last issue is the field has become a race track for off road motor vehicles in the last 2 years creating the same conditions and noise. Will this continue? Again I just got out of the hospital late last night and should not be around anyone as of this nasty virus bug going around, So I am hand delivering my concerns to Mr Ray Belair at 2.30pm today March 15, 2016 and ask that my questions be answered before any permit is issued The questions are not unreasonable.

You may start coughing more and have more mucus. This flare-up is called a COPD exacerbation (say "ig-ZAS-ur-BAY-shun"). A lung infection or air'pollution could set off an exacerbation. Sometimes it can happen after a quick change in temperature or being around chemicals. Work with your doctor to make a plan for dealing with an exacerbation. You can better manage it if you plan ahead. Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take. How can you care for yourself at home? During an exacerbation Do not panic if you start to have one. Quick treatment at home may help you prevent serious breathing problems. If you have a COPD exacerbation plan that you developed with your doctor, follow it. Take your medicines exactly as your doctor tells you. • Use your inhaler as directed by your doctor. If your symptoms do not get better after you use your medicine, have someone take you to the emergency room. Call an ambulance if necessary. • With inhaled medicines, a spacer or a nebulizer may help you get more medicine to your lungs. Ask your doctor or pharmacist how to use them properly. Practice using the spacer in front of a mirror before you have an exacerbation. This may help you get the medicine into your lungs quickly. • If your doctor has given you steroid pills, take them as directed. • Your doctor may have given you a prescription for antibiotics, which you are to fill if you need it. Call your doctor if you use the prescription. • Talk to your doctor if you have any problems with your medicine. Preventing an exacerbation • Do not smoke. This is the most important step you can take to prevent more damage to your lungs and prevent problems. If you already smoke, it is never too late to stop. If you need help quitting, talk to your doctor about stop -smoking programs and medicines. These can increase your chances of quitting for good. • Take your daily medicines as prescribed. • Avoid colds and flu. • Get a pneumococcal vaccine. file:///C:/ProgramData/Epic/81 /TempData/1 EB67F23A6424102B849C5E 1 AEC4CD9C/EPIC811158373... 3/14/201 Alaska Department of Environmental Conservation Dust and Potential Heal Why is dust a concern? EPA health research tells us that dust can cause health problems. People with heart and lung disease and those with breathing problems can be impacted when inhaling dust. Even healthy people can have short term irritation when breathing dust. Dust is a nuisance, it settles on your tables, your coffee cup, your subsistence foods, and salmon drying racks. Dust has been around for generations. Winds have been blowing dust off glaciers and dry river banks forever. We have lived with dust for thousands of years, but that doesn't make dust healthy to breathe. Now, we help throw dust back into the air with our four wheelers, trucks and cars. In the past three years the Alaska Department of Environmental Conservation (ADEC) received dust complaints from over 50 communities. Is dust a problem in your village? If you believe you have a dust issue, ADEC would like to help you find a solution to this potential health threat. Causes of Dust • Wind across dirt roads, runways riverbeds • Human activities on lots without vegetation • Quarry operations in gravel pits • Vehicles and four wheelers on dirt roads • Residents have told us that traffic is increasing in villages over the past 10 years, making the dust problem worse.

We would like to offer the following comments: 1. The project proposes to create an additional 133,482 square feet of impervious area on the parcel. This will result in greater than 1 total acre of impervious area on the parcel. Therefore, the project will require a stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. 2. The project proposes to disturb greather than 1 acre of area. It will therefore require a construction stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. 3. It was discussed that the applicant will revise the plans to include a pretreatment practice prior to Underground Storage System #1 and the Stormwater Detention Basin. 4. Work in the City Right Of Way (ROW) requires a permit before construction can begin. A "Permit to Open Streets or Right -Of -Way" can be obtained from the South Burlington Department of Public Works on their web site, or by stopping by their office located at 104 Landfill Road. 5. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. Regards, Dave David P.

Hi Bryan, I'm the new Development Review Planner for South Burlington and am following up on the 6 Ethan Allen Rd. project. In preparing for next week's Development Review Board meeting I was trying to locate where in the plans it states the front yard coverage and front yard setback calculations, but I couldn't locate this information. I did see the Zoning Information calculations on Sheet 1, which lists a number for the front setback; however, I'm not sure whether this is for Ethan Allen Rd. or Lime Kiln and we need to know the setbacks for both. The same is needed for the front yard coverage calculation. If you could point me to those calculations in the plans or provide them to me before the end of the day that would be appreciated.

The 1 st discussion was! I am not against business development. My issue is and has been all the toxic dirt dust that comes across the street onto my property and dust all over my house. That in the summer i cannot even open my windows when vehicles come and go driving on that property and more so if there is wind! Mr Senecal clearly stated i would just have to put up with it for 1 year! and gave no solutions to resolve the issue that would occur during he construction project. This demonstrated there was no concern to what would happen to my property and health. As clearly stated in several planning and zoning meetings in the past with this dust issue! I am a Disabled Veteran with many medical problems. One long time medical problem is i am allergic to Dust and once breathed in my nasal ( Nose ) develops sores from the dust and this last for a week! or longer. I cannot be breathing in dust. As i have in the past brought in evidence showing that the Government Dept of EPA has clearly said Dust and Dust form Roads is Toxic and gave you Mr Belair the EPA report on this and we all agreed that dust is toxic and conditions where set forth to stop this from happening when any occupation is allowed on that property. Which has you know was violated on several occasions when the snack bar was in place and vehicle traveling on and off the field dirt creating dust bowls coming across the street onto my house and property and vehicles. My whole entire house was just washed last fall and the front was repainted Sept 2015. Now i am not being unreasonable in asking the following; How will the town this time truly be involved in seeing that no dirt, dust be traveling onto my property, on my house, getting inside my house when my windows are open_? What about my vehicles being covered in dust from the construction project_? If this happens what will the South Burlington Planning and Zoning do to protect me as a resident with no prior issues in the last 18 months since the property hasn't been used there and no issues other then occasional traffic pulling off the side of that property as a parking lot. This area needs to be blocked off so cars cannot pull into that field or this problem will never go away! Its all dirt.. I am told which i must investigate that my property value could go down by having a huge commercial building sitting in front of my house obstructing views. If this is true and my property value goes down then some coarse of action must be addressed and will i be compensated for such loss before any project is to start.? I am told also that i need to contact Act 250_? as of the toxic dust traveling all over my property. This entire commercial project could very well create a financial burden upon me for the above and below reasons. There are filters that can be ordered for one house windows to stop dust from entering ones home when the windows are open. Will these be provided as needed to stop the dust from entering the inside of my home_? When Dust that comes onto my property, House and Vehicles must be removed and cleaned_? Vehicles as needed, House would need to be completely professional washed down once or twice during or at the end of the construction project. No high pressure sprayers can be used, My house was hand washed down with dawn soap and soft vehicle was brush. This prevents high pressure water from getting into the air holes where the insulation is inside the roof. We need need some sort of legal agreement to compensate for these clean up as needed. I will have my professional tv camera set up and running as in the past to show this clearly happens and the dust bowl comes directly onto my property. I am asking for a delay on this building project until all concerns have been resolved. I have asked my lawyer to give me a referral to an appropriate lawyer should we not be able to address and resolve the above concerns. It would seem to me that all parties should get together with Ray Belair at his office prior to any meeting on March 15th, 2016 at 7pm. To hopefully and possibly resolve all issues and concerns at hand.

Questions and Comments are italicized below and our responses follow each question. Landscaping Comments from City Arborist, Craig Lambert: 1. Islands in parking lots should be filled to a depth of 2.5 ft with loam or sandy loam planting soil to support plant growth. Response: Understood, a note has been added to sheet 3 requiring that all islands receive 2.5-ft of sandy loam material, see SH.3 Landscaping Plan'. 2. I'd be hesitant to use 'Slender Silhouette' Sweet Gum in parking lot island as it is boarderline hardy. A sheltered location for this species would be more advantageous. A tree with a wider crow in also recommended since part of the reason for planting trees in parking lot islands is shading of the parking lot. I think more perimeter/island trees maybe required given the number of parking spaces to meet the Land Development Regulations but I could be mistaken. Response: The Slender Silhouette' Sweet Gum was chosen because of its salt tolerance and narrow crown. The trees will be located within curbed landscaped islands in locations that will receive a lot of truck traffic. A mature tree with a larger crown designed to shade a parking lot could become an issue with the tall trucks driving around the islands. Each island will also have a pole mounted light that could be blocked out by a large crowned tree. Shade trees have been used 13 COkP(JKATE DRIVE ESSEX JUNCTION VERMONT 05452 TEL 802 878 9990 1 FAX 802 878 9989 1 obca@olearyburke.com around the parking lot to the north east because the parking lot is only accessible by cars and the trees have not been proposed under the pole mounted light. 3. There is an existing Norway Maple, approximately 10 inches in diameter in the City Right of Way which is located where the entrance to the property is to be built. It would be preferable to relocate the entrance and retain this tree, but if that isn't possible the city should be compensated for the value of this tree. Response: Unfortunately the entrance to the site cannot be relocated due to the adjacent flood plain. Heartwood Landscaping has quoted us a price of $900 to relocate the existing tree using a tree spade, please see SH. 3 'Landscape Plan' for the location of the relocated Maple. 4. Tree Protection measures should be specified on the plan for any existing trees that are to be retained. Response: Understood, a note has been added to sheet 3 under Landscaping Specifications requiring that all existing trees to remain be protected by construction fencing to provide a permanent demarcation of the limits of construction prior to the start of site work, see SH.3 Landscaping Plan'. 5. I'd recommend reducing the number of Blue Spruce and including some different species of conifer to improve diversity of the plantings. Response: Understood, a number of Blue Spruce have been replaced with White Spruce and Austrian Pine to improve diversity, see SH 3 'Landscaping Plan' 6. I wouldn't recommend giving landscaping credit for the proposed chain link fence. Response: Understood, an additional $8,257 worth of plantings has been proposed in order to meet the landscaping standards without the cost of the privacy fencing. Approximately seventy-five (75) arborvitaes have been added to help screen the outdoor storage area and 4 Honey Locust have been proposed around the north eastern parking lot perimeter. The new landscaping budget is $29,391. Attached please find a revised SH 3 'Landscaping Plan' with an estimate from Heartwood Landscaping Services. Comments from the Deuartment of Public Works: The first round of comments from Public works was done via an email dated 2/24/2016, see attached for our responses. A second set of follow up comments was provided by public works in an email dated 3/1/2016 and our responses have been provided below, see attached. 2 1. Do you have a report that accompanies the wetland delineation plan? Response: Natural Resource Consulting Services delineated all wetland on the property and produced a plan titled 'Wetland Map -Shand Property' which has been attached. A report was never written but a site visit with Tina Heath, District Wetland Ecologist was conducted on November 19, 2015. Ms. Heath followed up with an email dated December 8t", 2015 which stated "I have reviewed the delineation for which has been accepted based on a field review. This delineation has been accepted on 11/19/2015. Please note that due to the dynamic nature of wetlands, delineations are valid for five years. After five years the delineation will need to be reviewed and updated." A copy of the email from Tina Heath to Peter Spear and Brian Bertsch has also been attached. In addition, attached please find a copy of the completed general wetland application which was submitted for review and approval. The project has been placed on public notice which ended on March 2"d. A copy of the final permit will be forwarded upon receipt. 2. In reviewing the HydroCAD modeling, it appears that the site would be more accurately represented by using a "weighted-Q" runoff calculation than a "weighted-CN" runoff calculation. As noted on Hydrocads's website "composite CN values should be used only for interspersed runoff areas that cannot accurately be divided into independent sub -areas. " While the 17, 000 sq. ft. Outdoor Storage area is arguably part of an interspersed runoff area, the majority of the impervious surface in the "Site" subcatchment discharges directly to a catch basin and into the underground infiltration system. The model and design should be adjusted to infiltrate the entire runoff volume generated by the impervious surface during the WQ storm event, as required by the City's LDRs. This might be simply accomplished by modifying the infiltration rate to more accurately represent the actual infiltration rate of the system, if the soil boring results permit. Response: The HydroCAD modeling settings have been changed from a "weighted-CN" runoff calculation to a "weighted-Q" runoff calculation. Please see the attached revised HydroCAD model. 3. The Storm System Maintenance note on Sheet S2 should include discussion of removal of sediment from catch basins, underdrains, pond forebay and outlet structure. Response: A note has been included stating that all catch basins and the outlet structure shall be inspected annually and cleaned out when the sumps capacity has been reduced to 50%. The pond forebay has been removed since the WQv standard is being met by the two underground infiltration systems. The pond is now acting as a dry 3 detention basin to provide storage for the 1-yr, 10-yr, and the 25-yr standards. The sediment collected in the isolator rows shall be inspected annually and cleaned out when sediment accumulates to more than 9 inches. Please see the attached SH S2 'Stormwater Details', SH S3 Underground Storage System Details I' and SH S4 'Underground Storage System Details II'. 4. The Roof Drain infiltration Trench detail on Sheet S2 should be revised to more clearly depict relative dimensions. Response: The roof drain infiltration trench has been replaced with an underground storage system to meet the City's requirement of infiltrating the entire Water Quality storm event. Please see the attached SH S2 'Stormwater Details' to see the revised detail. 5. Trash Rack detail on Sheet S2 - Where is this utilized in the project? Response: The trash rack is to protect the orifices of the outlet structure from debris and vegetation growth which leads to clogging, see Outlet Structure detail on SH S2 'Stormwater Details' for more information. 6. The proposed grade and turning radius of the embankment still prohibit accessing the entire forebay in order to excavate accumulated sediment and load it into a truck. Response: The pond forebay has been removed since the WQv standard is being met by the two underground infiltration systems. The pond is now acting as a dry detention basin to provide storage for the 1-yr, 10-yr, and the 25-yr standards. The pond will have access from a gate in the rear of the outdoor storage area that leads to a 1 on 5 slope down to the pond. The pond will be privately owned, maintained, and inspected annually with annual reports filed with the State of Vermont. We are not proposing that this pond will be maintained by the vacuum truck owned by the South Burlington Stormwater Utility. 7. The proposed 6" cleanouts do not seem adequate for maintenance of a 550' + run of 24" pipe. Consider catch basin access points at the upstream point of the underdrain system and the bend at the corner of the building. Response: Understood, in addition to the seven (7) previously proposed 6" yard drains, two catch basins have been added to the 18" roof drain at the bend in the building and beginning of the run, see Sheet 1 '50-Scale Site Plan' El 8. Submit soil boring results once available. Response: One soil boring was completed near the proposed infiltration systems, boring B-4. The soils consisted of silty fine sand and the water table was recorded 17' below the ground surface. Building Design Comments from Planning Director Paul Conner: 1. Provide example of building materials. Response: The building will be a steel frame structure with Tan metal side paneling. A forest green painted horizontal stripe will align with the windows to provide a visual break along Lime Kiln Road. The entrances to units 1-3 will be decorated with a brick veneer and a forest green awning, matching the stripe along Lime Kiln Road, see SH. A100'Floor Plan Elevations'. 2. Consider change in colors, vertical break, larger windows, and separate unit signs on the western side of the building. Response: See above response and larger windows have been proposed along Lime Kiln Road to enhance the appearance of the building. 3. Any HVAC proposed on the roof? Response: All HVAC equipment will be mounted on the ground, see SH 1 '50-Scale Site Plan' for locations. 4. All retaining walls should be 5' away from the property lines. Response: The most eastern retaining wall has been relocated to provide a minimum of 5' separation from the right of way, see SH 1 '50-Scale Site Plan'. 5. 10% green space in parking lots. Response: The previously proposed impervious hatched area located at the bend of the building in the parking lot is now being proposed as green space. Plantings have also been included on both sides of the north eastern parking lot. With these revisions the parking area in the project will have 10.5% green space, see SH 8 'Parking Lot Green Space Calculations'. li► In addition to the application materials previously submitted on January 6, 2016 and February 24, 2016 attached please find five (5) full size, one (1) reduced, and one (1) digital sets of revised plans.

Justin Rabidoux From: Dave Wheeler Sent: Friday, February 12, 2016 8:48 AM To: Tom Dipietro Cc: Justin Rabidoux Subject: RE: Staff Development Review Meeting Plans Tom, Ray indicated that the draft LDRs do apply to this site plan submittal. I have included comment #4 to direct the applicant to the requirements. Please feel free to add any additional comments. The Stormwater Section has reviewed the "Lots 19, 20 & 21 Ethan Allen Commercial Park" site plan prepared by O'Leary - Burke, dated 12/4/14. We would like to offer the following comments: 1. The proposed project is located in the Winooski River watershed and discharges to a class 2 wetland. The VSWI Advisory Layer on the Agency of Natural Resources' online Wetlands Inventory Map shows additional wetlands that are not depicted on the submitted sketch. In a future application, the wetland delineation report developed by Natural Resources Consulting Services dated April, 2015 should be submitted along with the site plan for review. 2. The project proposes to create an additional 133,482 square feet of impervious area on the parcel. This will result in greater than 1 total acre of impervious area on the parcel. Therefore, the project will require a stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. 3. The project proposes to disturb greater than 1 acre of area. It will therefore require a construction "stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. 4. As the site plan propose more than 0.5 acres of impervious surface, the applicant will need to meet the requirements of §12.03 of the City's Land Development Regulations, as approved by the Planning Commission on November 10, 2015. These requirements include infiltration of the WQv on site using Low Impact Development (LID) practices in lieu of a stormwater detention pond. Stormwater ponds will only be approved if the applicant can demonstrate that it is unfeasible to infiltrate the volume of stormwater runoff specified in §12.03(C)(1). Additional requirements listed in the LDRs include, but are not limited to, controlling the post - construction peak runoff rate for the 1-yr, 24-hr rain event as to not exceed the existing peak runoff rate for the —1 same storm event. 5. Design of retaining wall adjacent to stormwater detention pond foebay precludes vehicle access for maintenance of forebay and outlet structure. 6. It appears that the infiltration trench is served by a 24" underdrain. Cleanouts or access points should be indicated for the underdrain. 7. Provide any soil boring information available in the vicinity of the infiltration trench system. 8. The applicant is requested to provide a copy of the stormwater modeling submitted to VT DEC in a digital format. 9. Work in the City Right Of Way (ROW) requires a permit before construction can begin. A "Permit to Open Streets or Right -Of -Way" can be obtained from the South Burlington Department of Public Works on their web site, or by stopping by their office located at 104 Landfill Road. 10. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. Thank you for the opportunity to comment.

Belair j O'Leary -Burke Civil Associates, PLC CIVIL ENGINEERING I REGULATORY AND PERMIT PREPARATION I LAND SURVEYING I CONSTRUCTION SERVICES I LAND USE PLANNING January 6, 2016 Mr. Paul Conner, Director South Burlington Planning and Zoning 575 Dorset Street South Burlington, VT 05403 RE: Site Plan Application Lots 19, 20, 21- Ethan Allen Commercial Park 6 Ethan Allen Drive, South Burlington, Vermont Dear Mr. Conner: We are writing on behalf of Allen Brook Development Inc. c/o Al Senecal, to request site plan review for a proposed 50,150 SF +/- commercial building on Lots 19, 20, 21 of the previously approved Ethan Allen Commercial Park. The site is located at 6 Ethan Allen Drive, at the intersection of Ethan Allen Drive and Lime Kiln Road. Currently the three commercial lots are undeveloped although recently the site has been used by Tim's snack shack, a small seasonal snack bar. A slightly different proposal was reviewed as a Sketch Plan by the Development Review Board in September 1, 2015, at which time the project consisted of three (3) commercial buildings and two (2) parking areas to access both sides of a two story building which was accessible from both Ethan Allen Drive and Lime Kiln Road. Feedback from the September 1, 2015 hearing was incorporated into the revised design for a single story commercial building accessible only from Ethan Allen Drive. The current proposal is to combine the three (3) commercial lots to create a 7.6-acre parcel and construct a new 50,150 sq. ft. commercial building located in the Mixed Industrial and Commercial (IC) Zoning District. The intent is to split and lease the building into three (3) units. Each unit will have approximately 2,000 sq. ft. of retail warehouse outlet space, to be used for office and showroom, and the remaining space will be warehouse space used to store inventory. A.H. Harris, a regional building material supplier, has signed a letter of intent to occupy Unit #1 and Poulin Lumber, a local supplier of wood panels, framing, and engineered trusses has verbally committed to leasing Unit #3. A tenant for Unit #2 is currently being sought. 13 CORPORATE DRIVE ESSEX JUNCTION VERMONT 05452 TEL 802 878 9990 1 FAX 802 878 9989 1 obca@olearyburke.com The site has been designed with the future tenants in mind where both loading docks and at grade overhead doors have been proposed to ship and receive products in bulk. Also proposed are two outdoor storage areas, which will be fenced for security and screened by landscaping and an 8-ft. high privacy fence which will surround each area. The buildings will be served by municipal water and sewer connections from Ethan Allen Drive. The buildings will have a maximum of 30 employees at any one time and will require 360 gpd of sewer allocation and 405 gpd of water allocation. Access to the site will be from Ethan Allen Drive, where a new 30' wide paved roadway will be built to serve the new businesses. The new intersection off of Ethan Allen Drive would be located approximately 230' south of the existing Ethan Allen Drive/Lime Kiln Road intersection. A traffic analysis was performed by Roger Dickinson, P.E. of Lamoureux & Dickson Consulting Engineers which examined the projects' impact at the Airport Pkwy/Lime Kiln Rd/Ethan Allen Drive/Shamrock Road intersection and the VT Route 15 (College Parkway)/Lime Kiln Road intersection. The traffic analysis predicted 286 average weekday trips and 11 PM peak hour trips to the site. The topography of the site consists of a flat area located along Lime Kiln Road then drops 20-25 feet to a gradually sloping area that drains to a small tributary of the Winooski River. A portion of the property is located with the 100-year flood plain which has been set at elevation 217.0', however no site work has been proposed within this area. A Class II wetland associated with the tributary has been delineated by Natural Resources Consulting Services and retaining walls have been used to ensure no impact to the wetland or associated 50-ft wetland buffer with the exception of a stormwater outfall pipe located at the bottom of the bank; the location of which was selected by Tina Heath, District Ecologist from the Watershed Management Division during a November 19th, 2015 site visit. The purpose of the stormwater outfall located within the 50-ft wetland buffer is to reduce potential erosion caused by discharging a stormwater pond at the top of a steep slope. A State of Vermont Conditional Use Determination for the wetland impacts has been submitted and is pending; a copy of the issued permit will be forwarded to the City upon receipt. The site has been designed to manage both stormwater quality and quantity. An infiltration trench has been designed to collect all stormwater runoff from the building's roof and infiltrate it back into the groundwater supply and a detention pond with a permanent pool has been designed to treat and detain all runoff in accordance with the State of Vermont treatment standards. A State of Vermont Stormwater Discharge permit application has been submitted and is pending; a copy of the issued permit will be forwarded to the City upon receipt.

Project Engineer Ethan Allen Commercial Park - Lots 19-21 South Burlington, VT Traffic Impact Assessment Proiect Introduction LNP, Inc. proposes to a construct commercial/warehouse complex located on Lots 19-21 of the Ethan Alien Commercial Park. The proposed building will provide a total of 50,150 sf of gross floor area. The anticipated uses include industrial/construction supply office/showroom (6,000 sf) integrated with warehousing (44,150 sf). Access will be via a new curb cut onto Ethan Allen Drive located approximately 200 ft south of its intersection with Shamrock Rd. Lots 19-21 are part of the original Ethan Allen Commercial Park. This new traffic impact assessment (TIA) is being prepared for this Project due to the length of time that has passed since these lots were created. As in past TIA's prepared by this office for development in Ethan Allen Commercial Park, this TIA will examine traffic conditions at the Airport Pkwy/Lime Kiln Rd/Ethan Allen Dr/Shamrock Rd and VT Route 15 (College Parkway)/Lime Kiln Rd intersections. Project -Generated Traffic The weekday peak hour vehicular trip generation of this Project has been calculated using published Institute of Transportation Engineers (ITE) trip generation rates'. ITE land -use categories #110 - General Light Industrial and #152 - Hi -Cube Warehouse/Distribution Center have been used to estimate the vehicular trip generation. Table 1 summarizes the estimated peak hour trip generation of this Project. Table 1 - New Project -Generated Peak Hour Trips Land -Use Gross Floor Area (sf) Avg.

Background Traffic Volumes 1 Trip Generation, Institute of Transportation Engineers, 91h Edition LDLamoureux Et Dickinson December 21, 2015 Consulting Engineers, Inc. Page 1 Airport Parkway is a federal aid urban street and a Class 2 town highway. It is also functionally classified as an urban minor arterial. An average of 7,400 vehicles per day travel Airport Parkway in the vicinity of this Project2. Background pm peak hour traffic volumes for this study were obtained from a turning movement count performed by this office at the Airport Pkwy/Shamrock Rd/Ethan Allen Dr/Lime Kiln Rd intersections on July 13, 2015 and a turning movement count performed by VTrans at the College Pkwy/Lime Kiln Rd intersection on June 8, 2015. To adjust the observed turning movement count peak hour volumes to a design hour (DHV) condition, hourly traffic volumes from VTrans Continuous Count Stations D040 and D530, located on US Route 7 in Colchester and on VT Route 289 in Essex respectively, were examined. The needed adjustment factors were obtained by comparing actual peak hour volumes on the days that the turning movement counts were performed to the most recent (2014) observed design hour volumes at those CTC stations. Because VTrans' most recent traffic projections are for declining traffic volumes in Vermont's urban areas, no adjustments were made for future background traffic growth (or decline) from 2015 to 2020. Additionally, since the building at 27 Commerce Avenue was not fully completed and occupied at the time of the July 2015 traffic count, its estimated pm peak hour trip generation has also been added to the foregoing background traffic volumes. Traffic Congestion Levels of service (LOS) at intersections are determined by average control delay; measured in seconds per vehicle. The methodology for analyzing LOS is established by the Highway Capacity Manual (HCM)3. The following analyses were performed using Synchro v8. Table 2 summarizes the delay thresholds for each LOS at intersections. Table 2 - Intersection Level of Service Criteria LOS Avg.

Although level of service (LOS) E is characterized by long delays, the volume/capacity (v/c) ratios for this movement remain well under 1.0. Thus, LOS E does not represent an unreasonable level of traffic congestion for this movement. The above results also show that this Project will have minimal impact on future traffic congestion conditions. Traffic Safety None of the intersections or roadway segments in the immediate vicinity of this Project have been identified as high crash locations in VTrans' 2010-2014 High Crash Location Report. The 2010-2014 five- year crash listing for Airport Parkway shows 10 crashes at the Airport Parkway/Ethan Allen Dr intersection and 3 crashes at the Airport Parkway/Shamrock Rd intersection. Five were rear -end crashes, four opposing direction crashes, two single vehicle crashes plus two unknown. Only two crashes resulted in injuries (one injury each). The resulting crash rate at the Airport Parkway/Ethan Allen Drive intersection equals 0.74 crashes per million vehicles. In comparison, the average statewide crash rate at urban minor arterial/urban collector intersections equals 0.561 crashes per million vehicles. LoLamoureux Et Dickinson December 21, 2015 Consulting Engineers, Inc. Page 3 Conclusion We conclude, based on the foregoing analyses, that this Project will not create an undue adverse impact on future traffic congestion or safety conditions. It should also be noted that this Project will contribute $11,000 ($1,000 per pm peak hour trip) to the City's Road Impact Fee to help fund future improvements at Airport Parkway/Ethan Allen Drive and other intersections.

Spear"' <pwsnres@comcast. net>, "'bbertsch@olearyburke.com"' <bbertsch@olearyburke.com> Subject: Wetlands site visit summary letter for 6 Ethan Allan Drive, South Burlingtoe Hi Pete and Brian, The following is a site visit summary for 6 Ethan Allen Drive in South Burlington: Please be advised there is a Class II wetland on you're the property located at 6 Ethan Allen Drive, South Burlington. This determination is based on a site visit conducted on 11/19/2015, made by Tina Heath, accompanied by Peter Spear and Brian Bertsch. PRESUMPTION OF SIGNIFICANCE: The subject wetland is contiguous to an area identified as a palustrine wetland on the Vermont Significant Wetlands Inventory maps and is therefore designated as a Class II wetland in the Vermont Wetland Rules. The Secretary has determined based on an evaluation of the functions and values of the subject wetland that it is a significant wetland and is therefore designated as a Class II wetland. At minimum, the subject wetland provides the following functions: water storage for flood water and storm runoff (VWR § 5.1), surface and groundwater protection (VWR § 5.2), fish habitat (VWR § 5.3), and erosion control through binding and stabilizing the soil (VWR § 5.10). Class II wetlands are protected under the Vermont Wetland Rules (VWR). Any activity that is not an allowed use designated in Section 6 of the VWR will require a State Wetland Permit. In addition, the U.S. Army Corps of Engineers (Corps) regulates discharge of dredge and fill material and mechanized land clearing in wetlands. For detailed information on Corps permits and regulations call (802)872-2893. In addition, your town may have local regulations regarding wetland protection. DELINEATION: I have reviewed the delineation for which has been accepted based on a field review. This delineation has been accepted on 11/19/2015. Please note that due to the dynamic nature of wetlands, delineations are valid for five years. After five years the cxcimeation will need to be reviewed and updated. PROJECT: The following project is proposed: Stormwater outlet pipe in association with a stormwater management system for a commercial building. A Vermont Wetland Permit will be required for the propose buffer impacts. For tracking purposes, your project has been assigned to wetland project number 2015-683. Please reference this number when you submit your application. There appear to be opportunities for further avoidance and minimization. We request that you address the following in your project design before sending in a permit application: • Please review the idea of shortening the outlet pipe so that the exit is further away from the wetland boundary, providing more buffer before the water enters the wetland. We discussed the idea of shortening the pipe, and adding some riprap at the outlet. • Please send a site plan that shows the cross section and details of the outlet pipe, as discussed in the field. If you have any questions, please contact me.

The site is located in the Mixed Industrial and Commercial (IC) Zoning District at the three way intersection with Ethan Allen Drive, Shamrock Road, and Airport Parkway/Lime Kiln Road with road frontage along both Ethan Allen Drive and Lime Kiln Road. Historically the site has been used by Tim's snack shack, a small seasonal snack bar with a gravel parking area and a few picnic tables. The topography of the site consists of a flat area located along Lime Kiln Road then drops 20-25 feet to a flat area located at the top of the bank to a tributary of the Winooski River. A Class II wetland associated with the tributary was delineated by Peter Spear of Natural Resources Consulting Services. The current proposal is to develop the site with three (3) new commercial buildings and associated infrastructure. The project has been proposed as a planned unit development to allow for multiple buildings and multiple tenants on a single building lot. Building 'A' will be a two-story commercial building with a footprint of 27,000 sq. ft. with four (4) loading dock spaces. We have designed the building to be built into the existing bank so that the building will appear like a single story building from Lime Kiln Road and a two-story building from Ethan Allen Drive. Three (3) local businesses have already expressed interest in leasing space in Building 'A'. The first floor will be divided into two units, Unit #1A will have a 2,000 sq. ft. retail and showroom area and 10,000 sq. ft. of warehouse space. Unit #1B will have a 2,000 sq. ft. retail and showroom area and 13,000 sq. ft. of warehouse space. Unit #2 will occupy the entire second floor and be used as indoor self -storage space which will be an accessory use t4 ��r � �t� ��€ice€X Wtajl)Wproouse outlet. Also proposed as t�r�)qf84ujtotnq ` 'xis �9 d�o@Ib both Units Units #1A and #1B. Both storage areas will be screened from the road by either fencing, building, or retaining wall. Buildings 'B' and 'C' will both be single story commercial buildings which fronts on Airport Parkway. Both buildings will have footprints of 2,000 sq. ft. and will be used as warehouse space. The intent would be to lease these buildings to some type of contractor who travels to different job sites but needs a home base to store materials and run their businesses. The existing topography allows for easy access to the new businesses by allowing for parking on both levels. Fifteen (15) parking spaces have been proposed behind Buildings 'B' and 'C' and thirty (33) parking spaces have been proposed behind Building 'A'. Access to the site will be from Ethan Allen Drive, where a new 24' wide paved roadway will be built to serve the new businesses. The new intersection off of Ethan Allen Drive would be located approximately 230' south of the existing Ethan Allen Drive/Shamrock Road intersection. Finally a second 'exit only' lane would be built to allow traffic from the project headed east toward VT Route 15 an easy exit onto Lime Kiln Road. The buildings will be served by municipal water and sewer, and stormwater runoff will be treated and detained on site. Additional details regarding building design, water and water demand, trip generation, landscaping and lighting and all other items typically reviewed as part of a site plan will be provided with preliminary plat application pending approval of this sketch plan. We look forward to discussing our project in greater detail at the next available Development Review Board meeting. Attached please find five (5) full size, one (1) reduced, and one (1) digital set of plans, application for subdivision plat review, and application fee of $983.00 ($350.00 (sketch base fee) + ($0.02/sq. ft. (non-residential) x 31,000 sq. ft. commercial space) + $13.00 (recording fee)) . Please feel free to call with any questions, 878-9990x106. Sincerely, Brian 1. Bertsch, P.E.

Dave's comments are numbered and our response follows each in red. The proposed project is located in the Winooski River watershed and discharges to a class 2 wetland. The VSWI Advisory Layer on the Agency of Natural Resources' online Wetlands Inventory Map shows additional wetlands that are not depicted on the submitted sketch. In a future application, the wetland delineation report developed by Natural Resources Consulting Services dated April, 2015 should be submitted along with the site plan for review. Understood, Natural Resources Consulting Services only looked for wetlands in the area proposed for development. As part of our preliminary plan application we will have all areas which show up on the wetland inventory map looked at and will submit a copy of the wetland delineation report. 2. The project proposes to create an additional 82,960 square feet of impervious area on the parcel. This will result in greater than 1 total acre of impervious area on the parcel. Therefore, the project will require a stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. Understood, a state stormwater permit will be required and will be submitted prior to issuance of a building permit. 3. The project proposes to disturb greater than 1 acre of area. It will therefore require a construction stormwater permit from the Vermont DEC Stormwater Division. The applicant should acquire this permit before starting construction. Understood, a state construction general permit will be required and will be submitted prior to issuance of a building permit. 1 of 4 8/24/2015 3:43 PM Fwd: SW comments, Lots 19, 20 & 21 Ethan ! jn Commercial Park https://mail2.sburl-tlm/owa/?ae=Item&t=1PM.Nc,, 4. In a future application, the applicant should provide a delineated drainage area map for the proposed stormwater treatment practices. Understood, as part of our preliminary plan application and state stormwater application we will submit a drainage area map for the post development drainage patterns. 5. The applicant is requested to provide a copy of the stormwater modeling submitted to VT DEC in a digital format along with the submission of a future application. Understood, we have not yet modeled the site but will provide this information as part of the preliminary plan application. 6. The applicant should show snow storage locations in a future submission. Understood, snow storage areas will be label as part of the preliminary plan application pending approval of the current sketch plan. 7. Work in the City Right Of Way (ROW) requires a permit before construction can begin. A "Permit to Open Streets or Right -Of -Way" can be obtained from the South Burlington Department of Public Works on their web site, or by stopping by their office located at 104 Landfill Road. Understood, this application will be submitted prior to issuance of a building permit. 8. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. We are agreeable to a condition which requires the applicant to regularly maintain all stormwater treatment and conveyance infrastructure, this is also typically a requirement of a state stormwater discharge permit as well. In summary we do not have any issues with Dave's comments dated 7-29-15, most deal with the final design and modeling of the proposed stormwater system. We plan to examine the design of the stormwater system in greater detail pending approval of this sketch plan application and prior to a future preliminary/site plan submittal. Let me know if you have any additional questions, Thank you.

Mr. Girard said he felt that the traffic issues were addressed today with Regional Planning. The yard will have locked gates with no lighting planned at this time. Some landscaping will be put in. Mr.. Weith suggested something up on the hill, possibly some evergreens. Mr. Girard said there is a lot of natural screening, but he could put trees further up the hill. Mr. Girard said if the business is successful, he plans in 3 PLANNING COMMISSION 25 November. 1997 page 6 years to develop a site with a building and amenities and major. landscaping. Mr. Weith noted the plan is for customers to bring vehicles to Commerce Avenue and employees will then bring cars to the Ethan Allen Drive location. He recommended a 24 ft. aisle for emergency access. Mr. Teeson asked about graveling the lot. Mr. Girard said he will go through one winter and see how it goes. The area is dry and grassed. Mr. Teeson said he would like to see trees moved up to the 240 ft. line. He then asked if this plan merges the 3 lots. Mr. Weith said it does not as all are conforming lots. There will be a stipulation that if any lots are sold, the applicant must return with an amended site plan. Mr..

Public Hearing: Final Plat application of Gregg Beldock requesting reapproval of the Planning Commission's 10/8/96 approval of a final plat application to amend a planned commer- cial development consisting of 150 residential units, a 61 room hotel, a 20,000 sq. ft. movie theatre (1000 seats), a 22,500 sq. ft. restaurant/retail/indoor recreation building, a 3500 sq. ft. restaurant with drive -through service, and a bank with drive - through service, located on Shelburne Road. The amendment consists of site modifications to parking layout and landscaping. Mr. Beldock said there is a question of the location of the center of the stream since it has shifted. Ms. Snyder of the Natural Resources Committee said the concern is with the actively eroding bank with trees creeping down the hill. There were cracks parallel to the stream. Mr. Beldock said he hired a hydrologist and brought in plants to stabilize it. He suggested the state be contacted to allow riprapping of the bank. He noted that the erosion will eventually affect the building. Ms. Snyder said that if the bank is riprapped, it will deflect the flow and cause erosion downstream. Mr. Dinklage suggested coming up with a mechanism to deal with the worsening erosion State of Vermont LAND USE PERMIT AMENDMENT CASE NO: 4CO643-14 LAWS/REGULATIONS INVOLVED 10 V.S.A., Chapter 151 (ACT 250) APPLICANT: GRD Corporation ADDRESS: PO Box 2008 South Burlington, VT 05407-2008 and Robert Shand 5 Ethan Allen drive South Burlington, VT 05403 District Environmental Commission #4 hereby issues Land Use Permit Amendment #4C0643-14, pursuant to the authority vested in it by 10 V.S.A., Chapter 151.

The ZBA is scheduled to review this project for a conditional use permit at its 11/24/97 meeting. This parking area is proposed to be developed on lots #19,20 and 21 of the Belter subdivision. This property located at 6 Ethan Allen Drive, 1880 and 1884 Airport Parkway lies within the IC and C.O. Districts and Floodplain Overlay District. It is bounded on the north by an undeveloped lot and an industrial building, on the west by Airport Parkway, on the south by Ethan Allen Drive, and on the east by several industrial buildings. Access/circulation: Access will be provided by a 32 foot curb cut on Ethan Allen Drive. This curb cut and access drive should be relocated so they are completely outside of the 100 year floodplain. The access aisle within the parking lot should be widened to 24 feet. Circulation on the site is adequate. 4 Coverage/setbacks: Building coverage is 0%. Overall coverage is on lot #19 is 18.6%, on lot #20 is 19.9% and on lot #21 is 14.3%. (maximum allowed is 70%). Front yard coverage along Ethan Allen Drive is 4.8% and along Airport Parkway is 0% (maximum allowed is 30%). No buildings proposed so setback requirements will be met. Parking: The proposed parking area will accommodate approximately 176 vehicles. This open field will be used "as -is" with no gravel or pavement. Landscaping: There is no minimum landscaping requirement, based on building costs, for this project. Staff recommends landscaping to screen this large parking area from view primarily from Airport Parkway. The applicant is proposing Red Maple trees along the westerly edge of the parking lot to screen it from Airport Parkway. A cedar hedge is proposed along Ethan Allen Drive. It may also be appropriate to plant landscaping on the top of the bank closer to Airport Parkway. Wetlands: The plan shows the wetland boundary beginning at elevation 218. Was this wetland boundary determined by a professional wetland expert? C.O. District: The plan shows the limits of the C.O. District along either side of the drainageway. No parking is proposed in the C.O. District. Floodplain: The plan shows the limits of the 100 year floodplain. No parking is proposed in the floodplain. Lighting: No exterior lighting proposed. Traffic: The applicant estimates that the average daily traffic for this development is 95 vehicle trip ends (vte's). The applicant should be aware that the road impact fee is $0. Other: --- the east -west -line through the middle of lot #21 should be removed. --- the lot coverage information should be revised to note that the correct lot size of lot #21 is 165,510 square feet. --- if any lot is sold or its use changed, the applicant will be required to return to the Planning Commission for a site plan amendment. 67 Ex M E M O R A N D U M To: Joe Weith, South Burlington City Planner From: South Burlington Fire Department Re: Plans Reviewed for November 25, 1997 agenda Date: November 12, 1997 1.
