Windsor, CT #050506 Existing Site Conditions ' The project property is approximately 11 acres, located at 35 Buckland Road, at the intersection of Tamarack Avenue and Buckland Road in the Town of South Windsor, Connecticut. The site is currently undeveloped; it is mostly meadows with some woods. The site is mostly type A and B Soils. The site is bordered to the east of Buckland Road by Lowe's, the site is also bordered to the north by Evergreen Walk, to its south by Smith Street and residential homes, and to the west by residential homes and undeveloped land. Proposed Development The proposed development will provide approximately 88,074 S.F. of gross leaseable ' retail area with 402 supporting parking spaces. The site is currently zoned Buckland Road Gateway Development Zone. The stormwater management system has been designed to meet the Town of South Windsor requirements. The details of the stormwater management design are addressed below. Public water,wastewater and other i utilities are currently available along Tamarack Avenue. iStorm Water Management The property drains to Plum Gully Brook, and the discharges to the Podunk River at jt Vinton's Millpond. The project property is approximately 11 acres, located at Tamarack Avenue in the Town of South Windsor, Connecticut. Current site drainage reaches this ' watershed through overland flow to a wetland southwest of the site. Additional discharge from Tamarack Avenue and Evergreen Run (Parcel "L") located east of Buckland Road are conveyed through a system of storm sewer piping to a detention pond located west of the subject site. Existing drainage area mapping for both Evergreen Run and Tamarack Avenue can be found in the two previously submitted drainage reports by Fuss &O'Neill Inc. 1.)

Windsor, CT #050506 Drainage Report Parcel"L"can be found in Appendix C to this report. Table 1 shown below lists a comparison of peak flow rate p p s between the previously approved Expo Center and Evergreen Walk Phase III for the entire site based upon existing developed conditions (with existing development at Evergreen Run and Tamarack Avenue) and the proposed site (Evergreen Walk Phase III) 2,10,25, and 100- year storm. The proposed stormwater management system incorporates proposed vegetated drainage Swale at the south(PDA-IA)that eventually connects to a proposed catch basin and storm piping network located at the end of the swale. This stormwater is then conveyed through the proposed piping system that leaves the site at the northwest corner to an existing piped system that eventually is piped to an existing detention pond. The existing idetention pond located west of the site,has been sized to accommodate development on this parcel. Additionally an underground infiltration system on-site of 48"perforated HDPE pipes collects runoff from the rooftops only of Building 200,300,400,500, 600, $� and 700 located in the proposed parking lot. This system has been sized to treat the lower j frequency storms for water quality measures and reduces the overall volume leaving the proposed development by infiltration. The remaining drainage area PDA-1B,that includes the wetland, conveys runoff from the remaining undisturbed area to the wetland ! that continues on to existing off-site Plum Gully Brook. f� Table 1: Overall Existing vs. Overall Proposed Peak Rates of Runoff—Total ' ,=, MM , , , Storm Overall Existing Flow Overall Proposed Flow Change (year) cfs) (cfs 100 18.11 12.89 -28.82 25 9.61 2.65 -72.42 10 5.62 1.68 -70.11 2 0.86 0.43 -50.00 Table 2: Total Post-development from Expo Center*vs.Total Post-development from Evergreen Walk Phase III TABLE 2:Total Post-deN lopment from expo Center*vs.Total Post-development from Evergreen Walk Phase III for 24 Hour Duration Storms Storm Total Post-development Total Post-development Change (year) from Expo Center* from Evergreen Walk N (cfs) Phase III cfs ' 100 22.10 12.89 -41.67 25 5.82 2.65 -54.47 10 2.56 1.68 -34.38 2 0.78 0.43 -44.87 1 * indicates values taken from Fuss&O'Neill Inc.Drainage Report Parcel"U May 2005 BL Companies 150 Trumbull Street, 6`h Floor,Hartford, Connecticut 06103, (860)249-2200 4117106 Site Engineering Report Page 6 of 32 ' Proposed Evergreen Walk Phase III Development,S. Windsor, CT #05C1506 The two tables indicates a net reduction in overall peak runoff rates in all storms resulting from the proposed stormwater management system. The existing drainage basin will benefit from the decrease in peak flow rates from the developed site. Rainfall data utilized in the modeling and analysis was taken from the State of Connecticut Department ' of Transportation Drainage Manual. On-site storm sewer design utilized a computer program called StormCAD that analyzed the storm sewer network using the rational method for the 25-year storm. The 25—year storm frequency rate is indicative of the Town of South Windsor. All subcatchment areas for each structure were inputted using a"c"value of impervious cover of 0.90 and a pervious cover of 0.30. The StormCAD model computations correspond with the Sheet t GD-1 for lines, slopes, and structure identifications. In summary,there is no flooding that occurs for each storm sewer structure for the 25-year storm.

I Executive Summary ' Parcel"L" This report summarizes the changes in drainage that will occur as a result of construction of a proposed Commercial Development north of the existing Lowes Drive on Buckland Road in South Windsor,Cr. The Proposed development will occupy approximately 3.4 acres of a 5.7 acre parcel. The site is currently occupied by an abandoned house,with some unkept lawn areas on the wrest side of the house,and wooded areas to the east of the house. Soils are Agawam sandy loss and Enfield silty loams,both of Soil Conservation Service soil type B,with some type CID soils in the rear (east)of the site within the wetland areas. Runoff from the proposed development's buildings and paring lots will drain to a detention basin located to the west,.across Buckland Road. This basin was constructed in conjunction with. the Evergreen walk project, and was sized to attenuate flows from portions of that r development, as well as flows from this parcel. Detailed calculations and drainage maps for flows resulting from the proposed Evergreen Walk and Expo Center development were summarized in a previous report titled."Drainage Report.Expo Design Center"Last revised on January 27,2003. Calculations developed for this report use base flows from,our January 27, 2003 report with additional runoff from the Parcel."L"site added to the model. The pre and post development flours for the detention basin(including proposed flows from this site)will be as follows: 2 1.95 .78 _i.17 10 9.56 2.36 -7.00 25 1.5.52 5.82 -9,70 100 27.77 22.10 -5.67 ' The proposed parking area storm drain P p p g age system was designed for the 25 year design storm, and will incorporate drainage structures with two foot sumps to maintain water quality.

Existing Conditions ' The subject property consists of-a 5.7 acre parcel located to the north of the existing Lowes Drive off Buckland Road,and across from the newly completed Evergreen Walk development. The site is currently unused,with an abandoned house and driveway located in the front ofthe parcel,and wooded areas to the rear of the parcel. The site also contains two separate wetland areas to the rear(east)of the parcel,and part of the detention basin constructed for the adjacent —owes/Target Plaza. Soils on the site are SCS soil type B. Proposed Conditions The proposed buildings will cover approximately O.64 acres. The adjacent parking areas will add.approximately L7 more acres of impervious area. The proposed additional impervious areas will increase the amount of runoff discharging from the site, if undetained. however, runoff willbe piped to the detention basin on the west side of Buckland Road,which was sized during the design of the Evergreen Walk development to accept flaw from this parcel. Accordingly, an 18"RCP storm pipe and manhole were installed across Buckland Road and stubbed on this property during the construction of Evergreen Walk to facilitate the future development of this parcel. The detention basin will have a total storage volume of approximately 5.6 acre-feet. The pond will have a 4 inch diameter low-level outlet,.an 8 inch diameter second stage outlet,and a third stage double catch basin: grate outlet. The bottom of the pond will be at an approximate elevation of 83 feet and the highest elevation of the basin's berm will be 90 feet. During the 100 year storm,there will be approximately 1 foot of freeboard within the basin. Preliminary groundwater data:indicates that the basin will be dry at least part of the yeah Under dry conditions,the basin can store the runoff from 1-1/2"to 2"of rainfall before discharging through the outlet. The basin is located.in an area of Merrimac soil,which the SCS classified as having a permeability oft to 6 iiich . .per.hour. Assuming a conservative 1"per hour,:the basin. will take 19 hours to drain completely when starting full at the low level outlet elevation... ' Storm sewer systems were designed to convey the 25 design storm for the proposed Yr � P p development. Minimum pipe cover is 3 feet, and minimum pipe slope is 1%, to maintain ' adequate pipe velocities in all areas. Methods rU.S.D.A.Natural Resources Conservation Service SCS TR-55 methods were used t v(SCS) ed to slop input information which was input into the Pondpack hydrologic computer model, which.is based on SCS TR-20 methods. Please see Appendix B for the Pondpack calculations and drainage map. The storm sewer systems were sized using the StormCAD computer model. Input information :for the model was derived using Rational Formula methods based on the drainage areas depicted in the drainage area map Mi Appendix A. Times of concentration for paved areas were assumed F.\P%\ 811A 48(Parcel L)\Drainagelara nrep.aoc {Torres: Fuss&O'Neffl Tic. 1 to be the minimum allowable time of5 minutes. The StormCAD output indicates that all ofthe proposed pipes will have adequate capacity. Since all storm systems outlet to the detention basin,the 25 year water surface elevation.in the ponds was used as the starting hydraulic grade line elevation in storm pipe calculations. Summary With the use of the proposed detention basin,proposed peak discharges from the site and from the proposed access road will be less than existing flows through the 100 year storm,as required by Town regulations.

Windsor,CT #050 S06 Storm Water Quality Overview This report reviews the storm water quality impacts of the existing retail building to remain and the proposed retail building project. The water quality Best Management Practices (BMP's) are designed to protect the wetlands and waters near the site from storm water runoff. Various BMP's are proposed at different points in the stormwater management system to renovate runoff prior to discharge. This project is designed to meet and exceed the Town of Hamden and the Connecticut DEP's requirements for the General Permit for the Discharge of Stormwater Associated with Construction Activity. The property is currently developed as an existing commercial/industrial building with associated parking and infrastructure. The part of the existing building and associated infrastructure and most utilities will be demolished and removed. The following is a brief discussion of typical pollution in storm runoff, proposed BMP's, and a summary of the pollutant removal effectiveness for this project. Typical Storm Water Pollutants & Sources Pollution in Storm Water Runoff When it rains a portion of that rainfall is absorbed by plants or soaks into the ground. That portion of rainfall that remains is called runoff and it is what we see flowing across streets and lawns during storms. That runoff is often carried by pipes and/or drainage ditches to streams and other waterbodies. Any pollutants that have accumulated on the ground between storms can be washed off and deposited in waterbodies by this runoff. Non-point source pollution is the term used to describe pollutants that may be present in storm water runoff because it can come from many sources and is discharged to waterbodies through various means. The following are typical pollutants that can be found in storm water runoff. • Debris; litter and other floatable materials such as plastic and cans can be washed down storm sewers out into waterbodies. • Sediment; sand and fine sediment, along with metals and oils that cling to the fine particles. Road sanding during the winter,and erosion are the typical sources of sediment. • Total Suspended Solids(TSS);is a measure of very fine sediment or other particles found in stormwater that can impact water quality. • Salt;road salt for winter snow and ice removal. Road salting is not a significant issue in tidal waters. BL Companies 150 Trumbull Street, 6'4 Floor,Hartford, Connecticut 06103, (860)249-2200 4117106 Site Engineering Report Page 29 of 32 Proposed Evergreen Walk Phase III Development,S. Windsor, CT #05C1506 • Oil& Grease;oils and gasoline residue can be washed off streets and parking areas during small frequent storms. • Trace Metals(Cd, Cu,Pb,Zn); fine particles of metal such as cadmium,copper,lead, and zinc can be deposited on impervious surfaces from air pollution, or from vehicles. • Phosphorous; a nutrient that stimulates algae blooms in fresh waterbodies,such as ponds and lakes,but is not generally a significant problem in tidal waters. Phosphorous can come from either residential,commercial,or farming activities. • Nitrogen;a nutrient that stimulates algae blooms in salt waterbodies. A significant source of nitrogen is excess fertilizing of lawns, commercial areas, farms, and municipal sewage treatment plants. • Bacteria; coliform bacteria is used as an indicator to evaluate when pathogens or viruses may present a public health hazard. These may be present in street runoff following large storms. • Oxygen Demand(BOD&COD);oxygen is depleted from the water when organic matter is decomposed by microorganisms. This organic matter can be from a variety of sources including landscaping clippings,pet wastes,excessive nutrients,etc. • Pesticides and Herbicides;when used around residential,commercial or agricultural areas, can be washed into aquatic ecosystems following storms. Storm Water Quality Protection Measures The proposed development proposes a variety of methods to address possible correct sources of pollution at the property,provide sediment and erosion controls during construction,control potential future pollution sources, and treat storm runoff when the project is fully developed. Measures During Construction Sediment and erosion controls will be installed during construction to prevent and limit impacts to the off-site receiving systems and water bodies. The sediment and erosion controls are designed to meet the requirements of the Town of Hamden and the Connecticut Guidelines for Soil Erosion and Sediment Control. These measures include anti-tracking pads at the construction entrances,sweeping off-site roads,haybales, silt fence,tree protection,permanent vegetative buffers, and internal controls. A temporary sediment basin and diversion ditches are proposed on the site to act as the primary sediment controls during construction. The site construction would be overseen by a construction manager and project engineer who would make regular reports to the Town BL Companies 150 Trumbull Street, 6 h Floor,Hartford, Connecticut 06103, (860)249-2200 4117106 Site Engineering Report Page 30 of 32 Proposed Evergreen Walk Phase III Development,S. Windsor, CT #05C1506 on the effectiveness of the controls, and modify them,if necessary. This monitoring would be in addition to the standard inspections by Town and DEP staff. Permanent Storm Water Quality Measures Post-Construction Storm Water Best Management Practices The Owner has developed a storm water management plan for this project to assure the storm water systems are maintained and run properly. The proposed storm water system has a variety of components designed to treat storm water runoff. BMP Locations and Functions The permanent storm water management system has several components that are shown on the Grading and Drainage drawings, and they perform various functions in treating storm water runoff • Landscape Strips are proposed lawn areas around the edge of the site,which will remain and be enhanced with native plantings to form a vegetated strip between the site and neighboring properties. The mowed lawns around the perimeter of the project will be seeded with meadow grasses. Buffer strips trap sediment and remove nutrients. Native shrub plantings will be added for aesthetics and wildlife food supplies and habitat. • Catch Basins are inlets to the storm sewer system that collect runoff and allow it to drain through the storm pipes. The catch basins(CBs) are equipped with 4-foot deep sumps and hoods over the outlets which trap road sand, floatable debris, and small amounts of other pollution that cling to the sediment particles. CBs have limited capacity to remove fine sediment due to the small storage capacity. CBs are distributed around the parking lot areas. Refer to the Grading and Drainage Plans for catch basin locations. • Infltration Systems are large, long beds of pipe set in crushed stone which provide cooling of hot runoff from impervious surfaces (thermal pollution), filters sediment,reduce peak rates of runoff,and protect against downstream erosion (detention). One infiltration system is shown on Grading and Drainage Plan GD- 1. The system collects the majority of roof-tops and provides water quality storage and treatment of the site stormwater. The outlet from pipe infiltration systems discharges into the proposed piped system that eventually discharges to an off-site existing detention basin. BL Companies 150 Trumbull Street, 6`h Floor,Hartford, Connecticut 06103,(860)249-2200 ................._._......_............ . 4117106 Site Engineering Report Page 31 of 32 Proposed Evergreen Walk Phase III Development,S. Windsor, CT #05C1506 Pollutant Removal Efficiencies Each BMP has different removal efficiencies,or ranges of pollutant removal. Most of the stormwater runoff from the developed areas of the site has to pass through several BMPs prior to discharge. A typical treatment sequence for runoff from a lawn or road is that runoff is collected in a catch basin where road sand and floating debris are removed,then the water flows via a pipe to sumps in the on-.site catch basins and skimmed by the hooded outlet pipe prior to discharging from the site. The catch basin sumps are where oil and fine sediment are collected, and later removed. Runoff then flows into the surface and subsurface Stormwater Detention Basins where it is recharged to groundwater. Because the run-off from the building rooftops are not subject to interaction with pollutants,the building run-off is discharged directly to the underground storage system. The stormwater flow from the Stormwater Detention Pipes is discharged though the outfall pipe and to the outfall spreader swale. The net result is that any possible pollutants that may be found in the storm water runoff from this project are treated or removed prior to discharge(see Table 1). This is a significant improvement over traditional storm systems used today, that discharge directly to inland wetlands via storm sewers and headwalls or paved leak-offs from roads and parking lots.

Sources: Controlling Urban Runoff A Practical Manual for Planning and Designing Urban BMPs by Metropolitan Washington Council of Governments, 1987,and Design of Stormwater Filtering_Systems, Center for Watershed Protection, 1996,and other sources. The removal efficiencies cited above are generally on the low end of the ranges noted in various studies in order to provide a conservative estimate of pollutant renovation. The catch basin pollutant removals cited are those stated by the manufacturer when the systems are designed in accordance with their suggested criteria. The manufacturer's removal efficiencies are supported by independent testing of installed systems. BL Companies 150 Trumbull Street, 6`h Floor,Hartford, Connecticut 06103, (860)249-2200 4117106 Site Engineering Report Page 32 of 32 Proposed Evergreen Walk Phase III Development,S. Windsor, CT #050506 The total water quality pollutant renovation within any stormwater system is the cumulative pollutant removal from all the BMPs that runoff encounters. This means that the CBs remove some pollution,then the Stormwater Detention Pipes renovate the runoff further,prior to discharge. The result is a highly effective stormwater system,with levels of redundancy,which will renovate stormwater runoff prior to discharge,so that the existing water quality of the receiving watercourse or wetlands is not degraded. BMP Maintenance The BMPs proposed for this project are designed to function properly with low maintenance by the developer during construction and after construction. Appendix E of the Site Engineering Report contains a complete Operations and Maintenance Plan for the long-term management of the project. This site plan application has incorporated the regular low-maintenance procedures that are necessary to ensure that all the BMPs will operate properly to maintain their effectiveness in renovating runoff. Conclusion The project is designed with a variety of stormwater quality Best Management Practices that will renovate storm water runoff prior to discharge to the receiving off-site conveyance systems or water bodies. The systems are designed with a high degree of redundancy to provide layers of stormwater renovation and protection from various sources of potential pollution. The multiple Stormwater Detention Systems provide a dispersed recharge to groundwater and receiving bodies. All of the BMP's are designed for all storms including the 2-year through the 100-year storm. Runoff from larger storm events is also treated, although controlling the smaller storm events is most important when considering water quality protection. This treatment level meets or exceeds both the Town of South Windsor and State of Connecticut standards. All the BMPs are designed to be easy to maintain by both the developer during construction and after construction. An Operations and Management Plan has been prepared as part of the Site Engineering Report.

Doolittle, P.E., Town Engineer ' Date: 6/13/06 v RE: App 06-22P The Shops at Evergreen Walk Phase III I have reviewed the proposed site plan for Phase III of the Shops at Evergreen Walk between Buckland Road and Smith Street, and I have the following comments: 1. Will one of the two driveways to this site from Tamarack Avenue be marked for delivery truck access? 2. On the Site layout plan, Note 26 is not applicable and notes 37 and 38 need to include a Town road as Buckland Road is a Town road. 3. The guardrail along Buckland Road needs to be completed where there are gaps in front of this parcel and be extended south to Smith Street. 4. The sidewalk along Buckland Road needs to be moved back 6 feet from the existing curb and labeled as such. 5. What is the separating distance between the sidewalk going down Tamarack Ave and this road? This should be at least 4 feet for a grass snow shelf, and needs to be a minimum of 2 feet with hard surface (stamped concrete) between the walk and curb. Label this on the plans 6. Handicap ramps need to be shown at all intersections and crossings on Buckland Road, Tamarack Ave, and within this site. 7. Show a pavement cut/match line where the driveway intersects Tamarack. 8. The size and model of the Vortechs stormwater treatment unit needs to be specified on the plans and details. 9. Is the dark, heavy line along both sides of the main site entrance drive and on the west side of Building A, a wall? Label these lines and if they are walls show the top and bottom elevations. 10.Show the top and bottom elevations of the wall on the west side of the site. 11.Show the overflow drains and/or underdrains from the rain gardens? 12.Are the soils and groundwater condition on this site suitable to rain gardens and the infiltration area? The rain garden detail has specific minimum depths to groundwater and ledge. What is the soils criteria for the infiltration units? Include soils test pit information to verify these conditions can be met. 13. Include some more spot elevations on the grading plan, especially at high and low points. Check the spot elevations by CB-8. 14.There needs to be a sidewalk connecting this site to Smith Street. 15.On the Storm Structure Information Chart show line O into MH-3 16.On the Utility Plan, continue the 8" sewer lines to buildings D and E and provide for at least two 6" laterals into these buildings. What are the expected sewer flows from these buildings? Will minimum cleansing velocities of 2.5 fps be achieved? 17.Where will possible outside grease traps be located for restaurants? 18.The Anti-tracking pad detail should show only a 50 foot long pad. 19.The plans need to include an operations and maintenance plan for the stormwater system and structures once the site is completed and open. 20.Check the landscape plan for conflicts with the site utilities. One island in the parking lot has a catch basin, rain garden and two trees. This is a lot for a small island. 21.The parking lot should be broken up with more landscape islands. (see my sketch) 22.The line striping for the parking spaces needs to be detailed as "hair pin" striping. 23.Should the underground infiltration system detail show a thicker stone layer on top and between the pipes? This system needs to be specified for H-20 loading. 24. Detailed plans signed and stamped by a Professional Engineer licensed in Connecticut will need to be submitted for any retaining walls requiring a building permit. 25.On Sheet DN-3 there are two details for cleanout in paved areas. Which sanitary manholes will have an inside drop? The Town WPCA has not been in favor of these because of access and maintenance difficulties. 26.The concrete crosswalks on site need to be stamped, colored concrete similar to the rest of Evergreen Walk. 27.Show the patterns and colors for the stamped, colored concrete areas. 28.WPCA review and approval is required for this site plan. 29. 1 need to receive a final drainage report to complete my review of the site stormwater drainage.

Phase II consists of the Highland Park Market building and the Old Navy building. 2. The Phase III site was approved for a single big-box user, Expo Design center, in February 2003. The Expo building was 90,250 square feet, with 358 parking spaces to be constructed and 30 reserve spaces, for a total of 388 spaces. At its closest point, the Expo building was 115' away from Smith Street and 146 feet away from the closest residential property to the west. The proposed Phase III has 88,095 sq ft of buildings, with 398 spaces proposed.The buildings are 145 feet away from Smith Street at their closest point, and 130 feet away from the closest residential property to the west. 3. Proposed maximum building height is 42.5 feet; 60 feet allowed. All parking is located outside of the 65' front yard setback. 4. Maximum impervious coverage allowed is 60%. In the Gateway zone, the entire project is treated as one lot for development purposes, so the cumulative impervious coverage on the entire 230-acre site will be about 22% including all approved site plans. The Gateway zone requires that "Areas reserved for open space and set aside to meet impervious coverage requirements shall be distributed throughout the site in such a manner that the land is visible (from_ public streets) and /or useable (e.g., for pedestrian circulation, outdoor entertainment and cultural events, bandshell, or arts/crafts shows). The Commission should review the plans to determine whether this standard is met. 5. The State Traffic Commission permit issued for the entire Evergreen Walk site includes the amount of retail contained in Phase III, thus no STC action is required. All Buckland Road widening and traffic signal installation was constructed during the Phase I & II construction, so there are no additional traffic improvements to be done on external public streets. 6. There is a sidewalk shown on Buckland Road and Tamarack Avenue. The previously-approved Expo plan included a walkway from Smith Street for the Appl#03-28P Shops at Evergreen Walk Planning Dept.Report convenience of the Smith Street neighborhood. If there are residents from Smith Street at this hearing, the Commission may want to try to ascertain whether the residents would like to have a walkway into the Evergreen Walk site. 7. The Phase III plan continues the traffic calming patterns established in Phases I and 11 with the use of stamped concrete crosswalks. There is a large amount of typical gray concrete walkways, some with a different scoring pattern; however, in the tradition of the Phase I and II sites, some of the gray scored concrete should be colored stamped concrete that matches the stamped concrete in the previous phases. Staff are also looking for a way to break up the expanse of parking in the middle. We have suggested use of stamped concrete down the middle aisle, but that ends up looking too much like a walkway and may confuse traffic flow. Jeff Doolittle has suggested a central island design that would improve the appearance of the parking lot. Another alternative is the use of stamped concrete within the parking lot aisles in such a way that it does not confuse drivers. 8. We note that outdoor storage is prohibited in the Gateway Zone, and that all business must be conducted within completely enclosed buildings. There are exceptions to this regulation for village-style shopping centers where outside merchandise display, such as kiosks or market carts, is an integral part of the theme and thus enhances the appearance of the site. The regulation is clear that this provision is not intended to allow outside display of merchandise typically sold inside retail stores in conventional shopping areas; rather, it is intended to encourage true pedestrian-oriented areas in a village atmosphere. As we point this out, we note to the Commission that LL Bean may be displaying kayaks, canoes and other outdoor recreational equipment on the outside of their building. 9. Architectural elevations have been submitted for all sides of all buildings. ADRC reviewed the plan on June 1 and was generally satisfied with the plan... ADRC did note that they have a big concern about rooftop screening and that all RTU's need to be strictly located inside the designated RTU areas on the plans. If there are to be any variations from this, the applicant must return to ADRC prior to installing any RTU outside the designated areas. ADRC noted that there would be confusion if the entire middle aisle in the central'parking area is treated with stamped concrete. Finally, ADRC noted that the landscape plan, especially the tree line and existing trees, needs to be accurate. 1 O.The applicant has carried through some of the architectural elements from Phase I, in particular the tower elements. Staff note that buildings A and F in particular are essentially 4-sided buildings, in that you will have a clear view of 2 Appl#03-28P Shops at Evergreen Walk Planning Dept.Report all four sides as they front on Tamarack Avenue, open into the center parking area, and will probably be at least partially visible from Buckland Road. There is a fair amount of EIFS surface on the side and rear elevations as shown, and it is not clear how much glass we can expect on the sides and rear of these buildings. I am concerned that the first impression of these buildings from Tamarack Avenue will be that they are the backs of buildings. We also need to find a better way to disguise downspouts, scuppers, and utility services and meters, which usually do not appear until construction drawings are completed. If these items are not addressed in advance, then there is a strong likelihood that the back of the buildings as seen from Tamarack Avenue will be similar to the backs of the existing Phase I and II buildings, only much closer and more visible from the street. Commissioners should review all sides of all buildings for adequacy of appearance. Some rooftops will be visible from Buckland Road. Given the extensive issues we have had with rooftop screening on Phase I, this is an area that needs to be fully addressed and locked up tightly prior to approval. I LSite lighting design duplicates the existing fixtures of Phase I and II. There is only one light pole located behind the buildings closest to Smith Street, and that pole is at the cul-de-sac end where there are no residences. All other lighting on the Smith Street side will be full cut-off building lights. 12.The requirement for parking lot landscaping is 12% within Buckland Road lots, and 10% for landscaping of interior parking lots. The details of landscaping within the center lot are still being explored. 13.The landscaping plan for Phase I included pedestrian amenities such as street furniture and directories. I can't determine from the landscaping plans whether the same attention to pedestrian amenities will be part of Phase III. 14.There are 4 service areas proposed, two of which are in out-of-the-way places, and two of which are located along Tamarack Avenue. One is behind a 5-foot retaining wall; the other will be fully visible from Tamarack. The dumpster. enclosure will be the same cedar enclosure that is currently being used in Phases I and II. The cedar enclosure is very attractive when new; the enclosures will need to be maintained well over time to keep their attractive appearance. 15.There are regulated wetlands on this site. This application was approved by the Inland Wetlands Agency/Conservation Commission on June 7, with a bond in the amount of$20,000 to ensure compliance with the erosion and sedimentation control measures and a bond in the amount of$25,000 to ensure installation of the stormwater structures. Also, the applicant is required by IWA/CC to retrofit 3 jo 141' -fill, Lr-P GJ LA rv,rt /1� 6,t AJJ f Appl#03-28P Shops at Evergreen Walk Planning Dept.Report the sediment chamber west of Tamarack Drive with a plan to be approved by the Town Engineer, prior to breaking ground for Phase III. 16.South Windsor Police Department has reviewed the site plans. Their only comment was that they would have preferred angle parking in the style of Evergreen Walk. 17.The Fire Marshal has reviewed the plans and has requested an additional hydrant located on the courtyard between buildings D and E by the curb to the parking lot. Also, the driveway behind building 300 needs to be marked with "Fire Lane—No Parking" signs and markings. 18.Public sewer and water are available in Evergreen Way. 19.A Site Engineering Report was submitted with the application. The report includes an Operations and Management Plan, which we have duplicated and provided to the Commission. There is no shopping cart management plan included at this time. Ideally, a shopping cart management plan would be included in the O&M plan, which would be provided to all tenants in advance of building occupancy. If the O&M plan is not revised to include a shopping cart management plan, any future tenant that has shopping carts that are used outside of the building, will require a shopping cart management plan in accordance with the regulations. I have requested that the site engineer revised the O&M plan to clarify that trash collection can only be performed between the hours of 7:00 a.m. and 10:00 p.m. We have had an issue with this item in Phase I and II; and it was only by the diligent efforts of a resident on Smith Street with an early-morning camera, followed by an early-morning site visit by the Evergreen Walk general manager, that finally put an end to 4:30-5:00 a.m. trash collection. 20.The Town of Manchester was notified of this pending application as required by State statute. 21.If this application is approved, the Planning Dept would like to see above-noted modifications finalized as thoroughly as possible prior to Commission action on the application. Also, the detail for parking space striping will need to be revised to hairpin striping as required by the Gateway zone requirements for 9' x 18' parking. 4 VC) b i kA� It rN ,mil �'�sr,�� r� � � � (c., {. � -� - j , ny/- VC1,14-C ly (d 0 oil l& Companies ECE1V>' June 30, 2006 no SWOON wu.fv uonb� ,.I. Ms. Marcia A. Banach Director of Planning Town of South Windsor 1540 Sullivan Avenue South Windsor, CT 06074 RE: Application#06-22P, Shops at Evergreen Walk Phase III Responses to Memorandum from Jeffrey B. Doolittle, P.E., Town Engineer,to Marcia Banach,Director of Planning, dated 06/13/06. Dear Marcia: On Behalf of Buckland Road Retail, LLC, BL Companies, Inc. is has prepared responses to the above referenced review comments. These comments along with our responses are as follows: 1. Will one of the two driveways to this site from Tamarack Avenue be marked for delivery truck access? Response: The western most driveway will be used for delivery truck access. Signage will be - installed only if it becomes necessary. 2. On the Site layout plan,Note 26 is not applicable and notes 37 and 38 need to include a Town road, as Buckland Road is a Town road. Response: Note 26 has been removed. Notes 37 and 38 have been revised to reference Town instead of State Requirements. Notes 37 and 38 were previously misnumbered and have been renumbered to 30 and 31 on Drawing SP-1. 3. The guardrail along Buckland Road needs to be completed where there are gaps in front of this parcel and be extended south to Smith Street. Response: Guiderail has been added to Drawing SP-1 in these areas. 4. The sidewalk along Buckland Road needs to be moved back 6 feet from the existing curb and labeled as such. Response: These revisions have been made to Drawing SP-1. 150 Trumbull Street, 6th Floor Hartford, CT 06103 Tel. (860) 249-2200 Fax (860) 249-2400 IN Architecture • Engineering • Planning • Landscape Architecture • Land Surveying • Environmental Sciences S+ar'� 1 5. What is the separating distance between the sidewalk goin -CC OY--e-d_ �I r e-y this road? This should be at least 4 feet for a grass snow shelf ( 2 feet with hard surface (stamped concrete)between the wa' plans. Response: We have added a 4'--0"wide sidewalk with a 2'-0"wide strip of scored gray concrete between the sidewalk and Tamarack Avenue. This 6'--0"total width is the maximum distance we can install due to the adjacent existing wood guardrail. 6. Handicap ramps need to be shown at all intersections and crossings on Buckland Road, Tamarack Avenue, and within this site. Response: Handicap ramps have been added on Tamarack Avenue, Buckland Road and within the site (see Drawing SP-1). 7. Show a pavement cut/match line where the driveway intersects Tamarack. Response: This notation has been added to Drawing SP-1. 8. The size and model of the Vortechs storm-water treatment unit need to be specified on the plans and details. Response: The treatment unit is a model#3000. This is specified on the plan (Drawing GD- 1) and detail(Drawing DN-4). 9. Is the dark,heavy line along both sides of the main site entrance drive and on the west side of Building A, a wall? Label these lines and if they are walls show the top and bottom elevations. Response: These lines are retaining walls. All retaining walls are now labeled as `RW; which is defined in the abbreviations table on Drawing SP-1. Top &Bottom elevations have been added to Drawing GD-1. 10. Show the top and bottom elevations of the wall on the west side of the site. Response: Top and bottom wall elevations have been added to Drawing GD-1. 11. Show the overflow drains and/or underdrains from the rain gardens? Response: Underdrain locations have been added to each rain garden on Drawing GD-1. 12. Are the soils and groundwater condition on this site suitable to rain gardens and the infiltration area? The rain garden detail has specific minimum depths to groundwater and ledge. What is the soils criteria for the infiltration units? Include soils test pit information to verify these conditions can be met. Response: Soil borings and logs prepared by JGI Eastern, Inc., indicate that all rain garden areas and the infiltration area have suitable soils for these uses. Depths to rock and groundwater inferred from the boring data meet or exceed the criteria specified on the rain 2 garden detail. Permeability and infiltration testing performed by JGI confirms that the infiltration rate of I inch per hour used in the design of the infiltration system is sufficient. Boring locations have been added to Drawing EC-1 and boring logs are included in the Site Engineering Report by BL Companies, revised dated June 30, 2006. 13. Include some more spot elevations on the grading plan, especially at high and low points. Check the spot elevations by C13-8. Response: More spot elevations have been added to Drawing GD-1. The incorrect spot elevation at CB-8 has been removed. The top of the frame elevation for CB-8 specified in the drainage schedule will control the grading at this location. 14. There needs to be a sidewalk connecting this site to Smith Street. Response:A sidewalk at this location is not currently proposed due to concerns about the public using Smith Street for convenient parking to access The Shops at Evergreen Walk. 15. On the Storm Structure Information Chart show line O into MH-3. Response: This information has been corrected on Drawing GD-1. 16. On the Utility Plan, continue the 8" sewer lines to buildings D and E and provide for at least two 6"laterals into these buildings. What are the expected sewer flows from these buildings? Will minimum cleansing velocities of 2.5 fps be achieved? Response: The Utility Plan has been coordinated with the building plumbing design. The sewer building exit points have been placed at locations that will allow collection from the entire building. Two additional stubs will be provided at Buildings D and E to allow for potential kitchen waste and connection to a grease trap should they become necessary(See Drawing SU-1). Flow computations have been performed which show that cleansing velocities will be above 2.5 fps for all building sewers. Flow Computations are included in the Site Engineering Report by BL Companies, revised dated June 30, 2006 17. Where will possible outside grease traps be located for restaurants? Response: Two outside grease trap locations for possible future use have been added to Drawing SU-1. Stubs will be installed for connection to the grease traps if they are required. 18. The anti-tracking pad detail should show only a 50-foot long pad. Response: This detail has been corrected to show a 50 foot long pad. 19. The plans need to include an operations and maintenance plan for the stormwater system structures once the site is completed and open. Response:An Operations and Maintenance plan has been included in the Site Engineering Report by BL Companies, revised dated June 30, 2006 3 V 1 ONS 20. Check the landscape plan for conflicts with the site utilities. One island in the parking lot has a catch basin,rain garden and two trees. This is a lot for a small island. Response: Conflicts have been checked between the Landscaping and Utilities and have been corrected on Drawings SU-1 and LL-1. 21. The parking lot should be broken up with more landscape islands. (see my sketch) Response: We have not added more landscape islands in the center parking field(as shown on your sketch) due to traffic flow concerns. We have added decorative paving insets that will be colored stamped concrete in a "brick red"herringbone pattern. The "brick red"will be similar in color to the Modular Cherry Velour A brick of buildings A, D, E&F. 22. The line striping for the parking spaces needs to be detailed as "hair pin" striping. Response: The parking space detail has been changed to "hairpin". This detail is shown on the Haddscape Plan (Drawing H01). 23. Should the underground infiltration system detail show a thicker stone layer top and between the pipes? This system needs to be specified for H-20 loading. Response: The stone thickness has been increased to 6-inches above the pipes. The Infiltration system has been designed for H-20 wheel loading. 24. Detailed plans signed and stamped by a Professional Engineer licensed in Connecticut will need to be submitted for any retaining walls requiring a building permit. Response: Signed and stamped retaining wall designs will be provided prior to construction. 25. On Sheet DN-3 there are two details for cleanout in paved areas. Which sanitary manholes will have an inside drop? The Town WPCA has not been in favor of these because of access and maintenance difficulties. Response: One cleanout detail has been removed from Drawing DN-3. No drop sanitary manholes will be required for the project. The internal drop manhole detail has been removed from Drawing DN-3. 26. The concrete crosswalks on site need to be stamped, colored concrete similar to the rest of Evergreen Walk. Response: We are matching the existing colored stamped concrete at all crosswalks. The existing color is a tan/orange color in a running bond pattern. 27. Show the patterns and colors for the stamped, colored concrete areas. Response: Please see the attached pdf(Figure A-7). 28. WPCA review and approval is required for this site plan. Response:Plans have been submitted to the WPCA for review/approval. 4 V1 BMW29. I need to receive a final drainage report to complete my review of the site stormwater drainage. Response: A revised drainage report is included within the Site Engineering Report by BL Companies, revised dated June 30, 2006 which accompanies this letter. Eight copies of the Revised P&Z submission plan set(22 sheets)accompany this letter for your review.

Banach, Director of Planning CC: Chris Wichmann, Poag &McEwen; Jeffrey Doolittle, P.E.,Town Engineer Date: 7/6/2006 Re: Shops at Evergreen Walk, Phase III We received your revised plans for the above-referenced project yesterday. I have compared the revisions with my review memo dated June 7, my report to the Planning and Zoning Commission at the June 13 public hearing, and comments made by Commissioners at the public hearing. Many of the requested modifications have been made, but there are still some outstanding items, as follows. Building Elevations(received from Jason Setty on 7/5 via e-mail) 1. Elevation A (facing Tamarack Ave): Looks like we lost glass and substituted EIFS; now it looks more like the back of a building than it did originally. 2. Elevation B (facing Tamarack Ave): Whole facade should be glass (or other very interesting features). 3. Elevation C: Unless the applicant can demonstrate that this fagade will not be very visible from either Tamarack Ave or Buckland Rd, the elevation needs less EIFS. 4. Elevation K: Same comment as Elevation C. 5. Elevation X (This is the fagade that customers will see as they exit LL Bean): Lost awnings, added diamond scoring to EIFS. No glass at all. Needs work. 6. How are utility service areas being handled on the backs of very visible facades? Rooftop Unit screening Appears that LL Bean has unscreened RTUs (with a note that says locations to be determined).Will the RTUs be visible from Buckland/Tamarack/Smith streets? Main Parking Lot 1.

Herringbone diamond pattern in the parking lot looks good. Parking lot could use a few more of them. 3. Sheet SP-1 still specifies a single white line for parking spaces instead of hairpin striping (note#17). Other items 1. There is an excess of typical gray concrete sidewalk, all the way to the edges of the center parking area. The strips of"scored gray concrete" between the center parking lot and the conventional concrete sidewalks should be modified to stamped colored concrete to match the theme set in Phases I and 11. 2. There still needs to be either an A-2 boundary certification or a reference to an actual A-2 certified plan that is filed in the Town Clerk's office (include the Town Clerk's map number). The applicant indicated at the June 13 public hearing that the dumpster located next to building A could be moved away from Tamarack Ave. This has not been done. Also, there is still no dumpster enclosure detail. 4 The "Typical Rain Garden" detail on sheet LL-3 refers to a house lot and shows a typical house lot. This is not a house lot. J 5. Applicant needs to work with the Fire Marshal to design the fire pit so that his safety concerns are addressed. 6. The water lines have been revised. The Fire Marshal now needs a fire hydrant between buildings E and F, rather than near the fire pit area as previously requested. 7.

These items need to be resolved prior to the start of construction for Phase III, which at this time is anticipated to be no later than September 1. 1. Median irrigation: Water line in southern-most median still not attached to Manchester. 2. RTUs: Southern-most stretch of Buckland,Road needs additional landscaping. I met with Chris Wichmann;to'day, we reviewed the area that needs additional landscaping, and additional evergreen trees will be planted, most likely in the fall to maximize survival. 3. Buckland Road final as-builts; monumentation at Deming Street; and 4. Retrofitting of sediment chamber off end of Tamarack The applicant has submitted plan revisions to address many of the items raised at the June 13 public hearing. I note the following: 1. The elevations for the shops facing directly onto Tamarack.(elevations A, B): it appears that the applicant received mixed input from the Commission regarding whether these facades should be designed to look like the front or the back of the stores. Staff strongly recommend they be designed to look like the front of buildings 2. Elevation X, which will be seen by everyone exiting LLBean, is not very visually interesting even with the addition of diamond pattern scoring on the EIFS. The applicant has agreed to wrap the glass from the front around the corner into the first bay, and to add the awnings that were inadvertently removed back into the plan. 3. There is an excess of typical gray concrete sidewalk, all the way to the edges of the center parking area. Staff recommend the addition of substantial amounts of stamped concrete, preferably between the conventional sidewalk areas and the parking lot. Jeff Doolittle will comment on this further in his update. A. Applicant needs to work with the Fire Marshal to design the fire pit so that his safety concerns are addressed. 5 i I I ��,�-�. � r MEMORANDUM To: Marcia Banach, Director of Planning From: Jeffrey B. Doolittle, P.E., Town Engineer Date: 7/11/06 RE: App 06-22P The Shops at Evergreen Walk Phase III have reviewed the revised site plan for Phase III of the Shops at Evergreen Walk between Buckland Road and Smith Street, and I have the following comments: 1. Sign the western driveway to this site from Tamarack Avenue for delivery truck access. 2. On the site plan show a handicap ramp at the intersection of Buckland Road and Tamarack Ave. 3. The soils boring logs indicate that the infiltration area will be in a silt layer. Additional information needs to be provided to show that the permeability and infiltration capacity of these soils is sufficient for the infiltration system. 4. The sewer flows expected from these buildings needs to be included in the sanitary sewer computations, based on the uses and fixtures in each building to compute that minimum cleansing velocities of 2.5 fps will be achieved. Include calculations for the velocity in a 6" pipe at 1% slope. 5. Add a note to sheet SP-1 that the parking spaces shall be striped with "hair pin" striping. 6. Add a note that the underground infiltration system is to be constructed for H-20 loading. 7. The 2 foot concrete strip between the sidewalk and Tamarack Avenue and the concrete buffer between the curb and sidewalk on site needs to be stamped and colored to match the rest of Evergreen Walk. I believe this can be done with an integral concrete curb. 8. Revise the rain garden detail to pertain to this site and not residential house lots. 9. The Hardscape Plan shows a stamped concrete crosswalk across Tamarack Ave and Buckland Road at this intersection. Verify that the traffic signal can accommodate pedestrian walk signals for these crosswalks. I suggest these crosswalks be "Duratherm"or a similar material rather than stamped concrete. 10.The COX cable box on Buckland Road needs to be screened with landscaping. 11.1 have some questions for the Engineer about the site storm sewer design and the stormwater operations and maintenance Plan 12.WPCA review and approval is required for this site plan. Please call me if you have any questions. Appl#03-28P Shops at Evergreen Walk Planning Dept.Report UPDATE July 11, 2006 Items still outstanding from Phase I & II: how are we going to resolve: 1. Median irrigation: Water line in southern-most median still not attached to Manchester. 2. RTUs: Southern-most stretch of Buckland Road needs additional landscaping. 3. Buckland Road final as-builts; monumentation at Deming Street 4. Retrofitting of sediment chamber off end of Tamaracks The applicant has submitted plan revisions to address many of the items raised at the June 13 public hearing. I still have the following concerns: 1. The elevations for the shops facing directly onto Tamarack still need to look more like the fronts of buildings (elevations A, B). 2. There are two elevations that, if it turns out that they are visible from either Buckland Road or Tamarack Ave, need work (elevations C, K). 3. Elevation X, which will be seen by everyone exciting LLBean, is not very visually interesting even with the addition of diamond pattern scoring on the EIFS. 4. Rooftop units screening: It appears that LLBean has unscreened RTUs (with a note that says locations to be determined on sheet A01). 5. Does the parking lot landscaping meet the 10% landscaping requirement? Would like to see more of the herringbone diamond pattern in the parking lot. 6. There is an excess of typical gray concrete sidewalk, all the way to the edges of the center parking area. The strips of"scored gray concrete" between the center parking lot and the conventional concrete sidewalks should be modified to stamped colored concrete to match the theme set in Phases I and II. 7. The applicant indicated at the June 13 public hearing that the dumpster located next to building A could be moved away from Tamarack Ave. This has not been done. Also, there is still no dumpster enclosure detail. 8.

All erosion and sedimentation control measures are to be in place prior to earth moving operations in each area and maintained/cleaned out during construction. Call Jeffrey Folger, Zoning/Wetlands 1 Enforcement Officer for inspection when measures are in place, prior to commencement of site work or if any problems/concerns arise during construction. 2. All topsoil stockpile areas to be protected(ringed with haybales or equal). 3. During construction of the road/driveway a crushed stone tracking pad is to be installed and maintained to minimize tracking of dirt/gravel on to Tamarack Avenue. Calcium chloride or water is to be used for dust control as required. Public Works 1. Three complete sets of approved/revised plans to be provided to Town prior to start of construction. They will be stamped by the Planning Department along with plans developer needs. Only approved plans are to be used on the job site. 2. The Engineering Department is to be notified forty-eight (48) hours prior to the start of major construction work with inspections and testing per Developers Checklist (requested, required) for the following: a. After site is staked out b. All drainage work c. Preparation of subgrade, compaction tests as per Developer's checklist. d. Preparation of subbase, six(6)inch lifts. e. Placement of bituminous concrete,two(2)inch layers maximum. 3. Certification of gravel used as subbase and processed stone for base will be required from an approved testing company. 4. Certification of all products used—storm pipe, structures,pavement, etc., shall be presented to the Town Engineer prior to installation. 5. No subgrade formation/base in frozen ground/snow. Same for pipe/structure installation. 6. Progress As Built Plans are to be submitted to the Town Engineer for approval prior to paving and after subgrade formation. 7. As built plans are to include horizontal and vertical location of all underdrains, footing drains, and sanitary sewers and house service laterals located as per revised as-built checklist. 8. All pipe and structures to be backfilled with free draining material compacted in maximum one foot lifts with approved compaction equipment or approved equal if deep trench is encountered. Any pipe or structure work requires inspection prior to backfilling. 9. Any problems and/or questions regarding construction of this project will be directed to Robert Nelson in the field at phone number 860-250-0547. A full list of contacts will be provided by Konover Company. 2 10. All filling to be done in accordance with Department of Transportation specification. To be compacted in maximum lifts and tested as necessary. 11. Job meetings will be held as needed, and can be called by the Developer or Town. Konover Construction will hold regular job meetings with their sub contractors on Thursdays. 12. Seventy-two(72)hours' notice needed for certificate of occupancy inspection. 13.

Separate Drain Layers Permits are needed for the sewer main into the site and for each building lateral and grease traps installed. 19. Extra care must be taken when compacting around structures such as catch basins and manholes. These spots often become problem areas in the future due to settling,therefore,the Town Staff/Inspectors will be requesting additional compaction tests in these areas. 20. Sanitary lateral locations should be tied down to existing structures and shown on the progress as-builts. 21. For concrete walks, 8: depth with reinforcements is required at driveway crossings. If the sidewalk is constructed before lot development, the locations must be indicated on the as-built plans. If a proposed driveway location is moved,the sidewalk must be removed to the nearest expansion joint and rebuilt to the proper depth with reinforcement. 22. During construction of individual sanitary sewer house laterals,the contractor shall prepare an as-built sketch on standard from provided by the Engineering Department. This form should be submitted to the Design Engineer/Surveyor for their use in preparing the as-built plan. The Engineering Department suggests that the contractor also show locations of foundation drains and water laterals on this form. Planning Department 1. Landscaping is to a installed in accordance with the approved landscaping plan. If there are changes required, contact the Planning Department. Additional landscaping installed on one part of a site will not preclude planting all of the remaining items shown on the landscaping plans. 2.

Comment: Western driveway needs to be signed for truck access. Response: In addition to the"No Trucks"in the median of the main access driveway, we have added two signs to the medians on Tamarack Avenue to help direct track deliveries to use the western driveway. (,Attached is a reduced copy of sheet SP.4 that displays this change). 2. Comment: Questions were posed regarding the handicapped ramp at the southwest corner of Tamarack.Avenue and Buckland Road, and it's relation to possible pedestrian access across Tamamck Avenue and/or Buckland Road. Response: The eaasting curb depression for a handicapped accessible ramp was not included in the survey base drawings provided to us. However,this curb depression will be utilized for installation of the new ramp displayed on the Site Layout Plan (sheet SP-l.). This work will be coordinated in the field. There are no plans to install any crosswalk striping across Tamarack Avenue or Bucklan.d Road,as none were proposed in these plans or the plans for the earlier phases of Evergreen Walk and no pedestrian signals exist at this intersection. 3. Comment: Details for"Cleanout in Landscaped Areas"and"Sanitary Sewer. Trench" should be modified to be consistent with Town of South Windsor standard details. Response: We have modified the cleanout detail to show the cap 6"below grade& a steel rod inserted below grade for locating purposes and have added a layer of filter fabric above the stone backfill for the sewer trench detail. 4. Comment: Concern was expressed regarding the soil in the area of the proposed underground stormwater infiltration area and the corresponding percolation rates of the soil. Response: While the geotechnical boring information for this area that you previously received does show the presence of silt,the percolation rates measured in the field 1 of 2 09/08/2006 13:26 18602492400 BL COMPANIES PAGE 02/13 are typical of the soil types encountered at this location. The attached excerpt From the updated & expanded geotechn.ical report indicates percolation gates of between 3.8 and 4.7 inches per hour for this area. The underground infiltration system was sized based on a percolation rate of 1 inch per hour. Therefore,the system and the soil beneath the system can more than adequately handle the proposed flows. 5. Comment: The sewer calculations provided in the report indicate the pipes would be flowing half full. However.,the calculations should show whether the flows anticipated to be generated by each building will achieve a minimum velocity of 2.5 ft/see for self cleamung. Response: The attached revised calculations are based on the anticipated flows,as determined by TES Engineering,the building design MEP engineers. These calculations show that for each building lateral,the requirement of 2.5 ft/sec is met or exceeded. 6. Comment; The DOT report in the stormwater calculations show that pipes C,CC,EE, G2, &G2 have flows that exceed their capacities. Response: While the flows do exceed the non-surcharged capacities of the individual pipes,the flows are contained within the overall pipe network under a surcharged condition. It should be noted that in all cases,the hydraulic grade line is below the catch basin grates and no ponding of water will occur within the parking lot A.profile showing the hydraulic grade line of some of these pipes was inadvertently left out of the engineering report that was previously submitted,but is now included herewith. 7. Comment: The Cox cable generator along Bucklaud Road needs to be seteened.. Response: A note has been added to the landscape plan indicating that this must be screened. In a meeting with.Cox representatives,they acknowledged that screening of this structure is their responsibilities. Please let me know if you feel this written response and the attached materials adequately address your continents. If so,we will proceed with.submitting final plans for stamping by the Planning&Zoning Commissioner and subsequent filing with the Town Clerk's office- Sincerely, '40- Jam o icz erkan w Senior Project Engineer BL Companies,Inc. 2 of 2 F:Vobs05\05C15o6\r)OCS\COIL;RFSP T..F,TTER\C•LTR-Dmliccic,d-05C150b-response-comment,-Ofif19o7-doc NOTE TO THE FILE: Date RE: Project Name UjC-t(L Pk a-q_ �S Appl# d.)

This signage would say no parking (see attached)and is the same sign used elsewhere on the property, attached to a sign post with a breakaway. Please let me know your thoughts and if it is approved whether I should bring a site change order to Town Hall.

Marcia Banach Director of Planning Town of South Windsor 1540 Sullivan Ave. South Windsor, CT 06074 (860) 644-2511 Dear Ms. Banach: As you are aware, we have finally finished Rockville Bank Park (formerly LL Bean Park) and per our agreement last Summer, once the park was completed the landscape letter of credit in the amount of$30,000 could be released. Therefore, I am requesting that Letter of Credit#S063380 in the amount of$30,000 be released. Additionally, per your e-mail to Elizabeth Maheu dated June 19, 2008, you indicated that two (2) of the wetlands letters of credit totaling $45,000 could be released. Therefore, I would like to request that these two letters of credit be released although I am not sure of their numbers (I would guess that they are numbers #S063377, S063378 and/or S063379) for a total of$45,000 although I am showing that these three (3) letters equal $70,000. Please advise if all three can be released.

As a follow up to our meeting today, it is our intention to contract the removal of invasive species and tree trimming on our property along Buckland Road in 2019. Per our conversation, this work will entail brush hogging the full slope of the hills, cutting, and removal of all invasive species including weeds, vines, sumac, knot wood, bamboo, bittersweet, and any others identified during the work but not visible at the time of the walkthrough. Additionally, all intended trees will be relieved of invasive species and trimmed to promote the health and growth of the tree(s). Any trees with limbs overhanging onto the sidewalk will be trimmed appropriately; all work will be completed with the assistance of a licensed arborist to maintain the health of the trees and plant life. Once this work is scheduled next year,I will notify you of the timing. If you have any questions in the meantime, I can be reached at the office at 860.432.3398, on my cell phone 860.836.8721,or via email at dfisher@poaglic.com.
