MEMORANDUM To: Marcia Banach, Director of Planning Jeffrey Folger, Environmental Planner From: Jeffrey B. Doolittle, P.E., Town Engineer Bobb Grillo, P.E., Project Engineer Date: 3/20/07 RE: App 06-60P Aldi Distribution Facility, Rye Street We reviewed the revised site plans(received 3/14/07)for the proposed Aldi Distribution Facility located at 295 Rye Street and I have the following comments. 1. Add notes/labels to sheets T5 and T7 stating that the detention basin is to be lined with clay from below the existing clay layer to elevation 72.5. This would prevent seepage out of the basin along the sand/clay interface during larger storms with at least one foot of freeboard for all storms. 2. On Sheet P2, show the concrete driveway starting back at least 5 feet from the edge of the Rye Street pavement. There needs to be a bituminous concrete driveway apron for this short distance so the concrete does not get damaged by Town snow plows, traffic or water. 3. Clarify the details for the detention basin outlet, including where the orifice is located. The labels on sheet T5 and T7 and details on sheets T6 and T9 do not agree. 4. On Sheet T5 show an underdrain along side the proposed stormwater outlet pipe from the outlet point up the hill until it is out of the groundwater. This underdrain can discharge into the storm manholes and alongside the final outlet pipe. This will capture groundwater that might otherwise follow the storm drain trench and potentially cause problems. 5. The following comments pertain to the on-site sanitary sewers and need to be answered prior to an application to the WPCA. A. Include a flow meter downstream of the proposed sewer pump station to measure the wastewater discharged to the public sewer. B. The oil separator does not meet State DEP requirements. C. More details are needed concerning the proposed "scrubber dump pit". If this unit is to be connected to the sewer and is intended to function as a grit separator, it will not meet State DEP requirements. D. The size and slope of the sanitary sewer line from MH 60 to the proposed pump station and the line from the pump station to the street have not changed. The slope and size of these two lines need to be updated. E. Change the sanitary laterals from the northwest side of the main building and from the drivers restroom to be 6"diameter pipe and have a slope of at least 2%. F. Remove the arrow pointing the wrong direction over the sanitary sewer lateral on the north side of the building. 1 G. Provide more details for the proposed sanitary pump station including the calculations sizing this pump station, the pump make, model and size proposed, the storage capacity of the station, the float elevations and alarm details. Provide an emergency power supply for this pump station. H. Provide an overall site plan on one sheet(at a scale of 1 in =200 ft)showing the proposed site development including topography and drainage so we can determine the developed area for the WPCA. Please call me if you have any questions. 2 MEMORANDUM To: Jeff Folger,Environmental Planner/Conservation Officer From: Jeffrey B. Doolittle, P.E., Town Engineer Date: 3/21/07 RE: App 06-60P Aldi Distribution Facility-Rye Street Improvements have reviewed the 3 revised sheets for the improvements to Rye Street associated with the Aldi Distribution Center that were submitted to the IWA/CC. I have the following engineering comments with regard to issues that may impact wetlands and sediment and erosion controls. Regarding Improvements to Rye Street: 1. Sheet CU1 shows temporary construction access roads to access the 24 inch culvert for replacement. Also shown are a cofferdam on the upstream side, a sediment basin and larger rip rap plunge pool on the downstream side,and a larger area for temporary limits of construction and the wetlands impact associated with this work. I think the replacement of this culvert can be done within the limits of construction shown on this plan. The final plans an details for the culvert replacement will be reviewed to insure they agree with this plan. 2. On Sheet RP2 the existing 15"cross culvert by Sta. 15+80 is labeled to be replaced and a rip rap energy dissipater has been included by the outlet to this pipe to help prevent further erosion next to the road. 3. Additional catch basins are needed on both sides of the proposed low point by Sta. 19+43. This would place a pair near George Road. To the east a pair of catch could be placed at about Sta. 22+75,just east of a driveway, and near Sta.26+00, about midway in the remaining distance to the high point. These catch basins need to be connected to the proposed catch basins at the low point and the proposed outlet pipe. 4. These measures will eliminate all runoff directly from the road to the gullies forming alongside the road. The gullies on the south side that start by Sta. 19+50 and Sta. 24+15 should be filled in with excess clean fill from the road excavation and stabilized as far back from the road as possible 5. The plans show 2H:1V side slopes from the road down to the 24 inch culvert. These will be stabilized with grass seed and plantings. I think the proposed plantings along with the elimination of runoff will adequately stabilize these slopes and there will not be any reason to install a bench in the mid point of the slopes. A bench on these slopes would cause the toe of the slopes to be pushed out farther from the road and result in greater wetlands impacts. 6. Use current TOSW details that call for 4 foot sumps in catch basins installed along Rye Street. I will work with the project engineer to complete the details on these plans. Please call me if you have any questions. 1 UJ/ZU/zuul TUE 13:53 FAA U002/003 MEMORANDUM. To: Denise Rwdcka,Director Inland Water Resources Division -From: Jeffrey Caiola,Civil Engineer III 'Inland Water Resources Division Date: March 13,2007 ..Re: Aldi Distribution Center 295 Rye Street Improvements South Windsor This memorandum is in reference to the above captioned project specifically an initial review for engineering concerns and a permit need determination.The January 24,2007 plans,revised March 4,2007 entitle"Aldi Distribution Facility, Off-Site Street Improvement Plans"show the majority of work on Rye Street. The proposed plans entail widening Rye Street to accommodate commercial vehicles. The embankments of the roadway are currently in poor condition.It appears that :portions of the embankment of Rye Street have failed and there have been several repairs. Rye Street is currently,curbed with several paved leak offs located on both sides of the roadway. Stormwater is directed down the embankment causing several slope failures. Currently.there are no catch basins located within the sag or low point of the roadway. The proposed plans call'for two catch basins, which will collect water -from the low point of the roadway and discharge to the relocated outfall. It appears that the stormwater management may be undersized for the section of :roadway. The designer may want to consider adding additional catch basins to eliminate roadway runoff from traveling down the embankment. Furthermore,the roadway embankment•is greater than 15 feet in vertical height and is steeper than 3:1. Therefore the designer should consider cross slope benches or other•engineered measures which are in conformance with the 2002 CT E&S Guidelines. The above referenced plans show mostly improvements to Rye Street and do not cover work on the proposed site. So the most of the comments below pertain to work shown on the plans and do not consider future development.Rye Street is not located•in an area where Stream Channel Encroachment Lines are established therefore a SCEL permit will not be required for the proposed development. However,please keep in mind that there is a FEMA flood plain(Zone AE) 03/20/2n7 TUE 13:53 FAX 9003/003 Aldi Distribution Center 295 Rye Street Improvements South Windsor established along the Scantie River located at the back of the property.A Flood Management Certification would be required if the project is being constructed with state funds and there is activity proposed in the floodplain.The existing 24" cross culvert located at roadway Sta.. 20+25 is being extended and relocated as part of the project. The culvert collects drainage from fairly a large drainage area. It is also unknown at this time how much runoff the proposed detention basins are collecting from the site therefore the designer should continue to coordinate with IWRD to verify if a Water Diversion permit would be required for the proposed development. i March 13,2007 Page 2 of 2 P.O.BOX 1167 425 SUWVAN AVENUE SOUTH WINDSOR,CT 06074 PHONE:860.291.8755 Is FAX:8onalsi .8757 c.com www.designprofessionalsinc.com CIVIL & TRAFFIC ENGINEERS / PLANNERS / SURVEYORS / GIS ANALYSTS / LANDSCAPE ARCHITECTS LETTER OF TRANSMITTAL To: Jeff Folger,Town of South Windsor Date: 3/14/2007 DPI Project No. 2282 Re: Revised Drawings for Rye Street WE ARE SENDING YOU: ❑ Attached ❑ Under separate cover via the following items: ❑ Shop Drawings ® Prints ❑ Renderings ❑ Specifications ❑ Copy of Letter ❑ Change Order ❑ • COPIES DATE NO.

Based on the revised plans for the off-site improvements dated 3/12/07,the following impacts to the wetlands and upland review areas will occur. For the direct wetland impacts,we divided the impacts into on-site,which includes all impacts to the wetlands due to the site construction and off-site which includes all impacts associated with the reconstruction of Rye Street. We further divided the direct wetland impacts into permanent and temporary. The permanent impacts include all areas where filling will occur,or where riprap stilling basins will be constructed. The temporary impacts include areas where during construction,temporary impacts may occur,but no permanent change is proposed. For upland review area impacts,no differentiation was made between temporary and permanent impacts. For calculation of cut and fill on the site,the volume of cut and fill is noted with fill volumes noted as second. Direct wetlands Impacts: : On-site: 350 S.F. (Permanent Impact) Off-site: 3,520 S.F. (Permanent Impact) Off-site: 900 S.F.(Temporary Impact) Total 4,770 S.F. • Upland Review Area Impacts On-site: 37,600 S.F. Off-site: 56,850 S.F. Total 94,450 S.F. Volume of cut/(Fill) Within Wetlands: On-site: 11.0 C.Y. (0 C.Y.) Off-site: 70 C.Y.(440 C.Y.) Total 81.0 C.Y. (440 C.Y.) Within Uplands review area On-site: 0 C.Y. (700 C.Y.) Off-site: 0 C.Y. (2,400 C.Y.) Total 0 C.Y.

I have reviewed the proposed plan with the following additional comments: Road Widening Portion All proposed catchbasin are required to have 4 foot sumps. The portions of the submitted details still show 2 foot sumps. The submitted revisions include a very general statement that the site contractor will determine the method to install the new cross culvert under Rye Street. This will not adequately illustrate the scope of disturbance to wetlands and watercourses on the site. The two options that have been brought forth are to either to jack the pipe under the road, or install via an excavated trench. The plans must reflect the method that will require the most area outside of the road bed to accomplish the task. The plans must show location and grading of all temporary access roads necessary, as well as the area needed to accommodate the work and all equipment needed. This information is needed to determine permanent and temporary impacts to the adjacent wetland areas. The narrative describes the de-watering plan but there is nothing shown on the plans that show where or if coffer dams will be installed to separate the work area from the watercourse. CC.

Folger—Environmental Planner/Conservation Officer Date: March 16, 2007 Re: Appl. #06-60P Review of the proposed Aldi's Distribution facility at 295 Rye Street. Revised plans dated 3/12/07 The proposed disturbance shown on the plans appears to reflect the activities necessary to effect the reconstruction of Rye Street. Town staff consulted with a construction contractor that specializes in jacking pipes. The estimated operation area was greater than originally shown. The latest revisions accurately show the larger area of disturbance. Access roads necessary to reach the work areas are shown on the plans with appropriate erosion controls Details for dewatering the southern work area are shown on the plans. Planting plans to stabilize the slopes reflect the greater planting density for selected shrubs as well as a higher seeding rate. The stabilization narrative specifies that fill and top soil will be certified free of invasive plant materials. The Stormceptor located at the outlet of the detention basin on the main site has been moved farther along the outlet pipe so as not to be influenced by mean water levels in the basin. The detention basin outlet has been altered to include drop structures within the pipe to further reduce flow velocities prior to entering the splash pad adjacent to the river. The graded shelf adjacent to the outlet of the basin has been enlarged to maximize the plant population within the basin along the flow path to provide additional biofiltration opportunities. The retaining wall proposed to be built along the southern parking lot has been moved further to the north and has an underdrain proposed which will remove ground water from the wall. The locations of the walls are now within the areas that are being disturbed as a part of the existing debris removal operation. The plateau area adjacent to the basin will provide approximately+/- 4 acres of meadow habitat. The location of the facility in the open portion of the field will exclude area wildlife from utilizing the field during fallow periods.

Doolittle, P.E., Town Engineer Date: 3/7/07 r9 RE: App 06-60P Aldi Distribution Facility-Rye Street Improvements I have reviewed the revised plans for the Aldi Distribution Center site work and off-site improvements submitted to the IWA/CC. I have the following engineering comments with regard to issues that may impact wetlands and sediment and erosion controls. Regarding Improvements to Rye Street: 1. By Sta.2+29, if the old cross pipe and concrete headwall on the south side of the road are not needed they should be removed. The plans show a connecting pipe to the stormwater system in Sullivan Avenue to the south. Does this pipe exist and which way does this drainage system flow? 2. The existing 15"cross culvert by Sta. 15+80 needs to be replaced lower and at a flatter slope so it does not interfere with the proposed drainage and still drains the field to the south with lower outlet velocity. Also, a rip rap energy dissipater needs to be included by the outlet to this pipe to help prevent further erosion next to the road. 3. Additional catch basins are needed on both sides of the proposed low point by Sta. 19+43. This would place a pair near George Road. To the east a pair of catch could be placed at about Sta. 22+75,just east of a driveway, and near Sta. 26+00, about midway in the remaining distance to the high point. These catch basins need to be connected to the proposed catch basins at the low point and the proposed outlet pipe. 4. Regarding the hydraulic analysis to verify that the proposed 24"diameter culvert is the proper size. More information including a drainage area map and flow path is needed to verify this analysis. The slope of this pipe needs to be lowered to lower the drainage outlet velocity to about 1-3 fps maximum to prevent further erosion of the stream channel. 5. Storm MH C should be a drop structure to provide for a lower slope in the 24"cross culvert under Rye Street and thereby reduce the outlet velocities. 6. Add a label/note that the existing culvert is to be removed or abandoned in place and 1n1t completely filled with cement grout. 7. More details are needed showing how the new 24"cross culvert will be installed. This includes a construction access path and work area down near both ends of this culvert, detailed plans for dewatering and temporary diversion piping as needed to install the new 24"cross culvert, and the construction method and sequence used to install the new culvert. 8. Remove the existing concrete pad, concrete headwall, and cross pipe at Sta. 24+17. 1 9. These measures will eliminate all runoff directly from the road to the gullies forming alongside the road. The gullies on the south side that start by Sta. 19+50 and S to 24+15 should be filled in with excess clean fill from the road excavation and stabilized as far back from the road as possible 10. Add notes to flatten and stabilize the steep side slopes along Rye Street near the 24'culvert as such: First, remove existing vegetation , stone, debris,topsoil, and any unstable/unsuitable soil from these slopes,Then add suitable fill to create 2:1 side slopes with 4"minimum topsoil to be planted with stable vegetation or stabilized with other suitable means as approved by the Town of South Windsor. 11. Use current TOSW details that call for 4 foot sumps in catch basins installed along Rye Street. Regarding site plans for the Aldi Distribution center. 12. The detention basin needs to have a typical outlet structure with the 8"orifice on the outlet pipe. The top elevation should be about the water surface elevation of the 2 year storm in the basin. This will provide access to the orifice for maintenance, prevent the stormceptor from being flooded and overwhelmed and will also help prevent the curtain drain from flooding. Verify that the notes and details for this outlet structure on sheets T5,T7 and T9 or T6 agree with each other. 13. Include a gravel access path constructed with 10"gravel under 4"topsoil from the detention basin to the drainage outlet and energy dissipator. This will allow for access to the outlet energy dissipator for inspection and maintenance. 14. Revise the permanent drainage maintenance and operations notes to include inspecting the detention basin, stormceptor,overflow structure and outlet energy dissipator monthly and after heavy rain storms and cleaning/repairing these detention/drainage structures twice yearly or as needed. will conduct a more complete review of the plans that are submitted to Planning and Zoning and issue further engineering comments at that time.

Folger—Environmental Planner/Conservation Officer Date: December 26, 2006 Re: App. #06-60P - Review of the proposed Aldi Distribution facility site plan—Plans dated 12/01/06. I have reviewed the proposed plan with the following additional comments: There are numerous erosion scars on the site as a result of surface runoff from the farm fields flowing over the highly erodable sand terraces. An analysis of the runoff adjacent to each of the gullies must be done to determine if runoff from the areas not proposed to be paved will continue to impact these areas. The high water table on the site may require that excavations be de-watered to provide a dry work area. Provisions must be made to provide a stable area to pump water into. These must be shown on the plans. The drainage on the site will be altered by the amount of impervious surface proposed. Surface and ground water that currently travels to the western gully will be significantly reduced. What is the current water budget to this gully? How will the diversion of drainage away from this area affect the hydrology to this watercourse? The retaining wall that is proposed to be built adjacent to the western watercourse must be eliminated and fourteen of the proposed truck parking spaces be relocated to other areas on the site. The construction of this wall is reasonably likely to adversely impact the functions of the adjacent watercourse. Sedimentation impacts to the watercourse are an imminent and unavoidable consequence to working in this area. The current slopes and drainage gullies leading into the watercourse show significant down cutting and head cutting. The soils on the terrace escarpment slopes are well documented throughout the Scantic River watershed as being highly sensitive to disturbance and development. Whole scale movement of an entire slope is possible where excess weight in the overburden is combined with groundwater movement along the subsurface clay layer. The area between the two catchbasins where the old house is to be removed must be abandoned as a parking area and not filled or paved. The proposed parking spaces can easily be moved to the west where the proposed access drive curves around the rear of the building. Catchbasins must contain traphoods to capture floatables, including hydrocarbons on site prior to entering the retention basin. The stormwater treatment train must also include a high efficiency gross particle separator prior to the retention basin. Tree clearing is proposed along the northern property boundary even where no parking lot or roads are present. These areas should be left alone where there are no conflicts with development. CC.

The roadway improvements are illustrated on plans prepared by Design Professionals and submitted to the Town Wetlands Agency. The proposed roadway improvements include some widening, new base coarse materials, new pavement overlay, adding road curbs, new catch basins and drainage pipes, and utility relocation work. In addition, re-grading is proposed to modify areas along the road including existing embankments which border a section of Rye Street and the adjacent wetlands at an existing stream crossing. Location: Rye Street, South Windsor, CT 1 Regulated Affected Area: The wetland and watercourse areas along the Rye Street project area have been delineated by a GZA Certified Soil Scientist and surveyed onto plans by Design Professionals. The proposed plans for the Rye Street roadway improvements have also been prepared by Design Professionals and shown on Figure RP1, RP2 and RP3. Details for the roadway work including the G� soil erosion protection and planting plans are on Figure D1, D2 and D3. . The wetlands and watercourses along the Rye Street corridor include a man- made drainage channel along the north side of the road approximately across from George's Road. The existing seasonally wet channel (Flags DC-1 to DC-4) receives surface runoff from a field along the south side of Rye Street through a small 15-inch RCP culvert which will remain in use. There are no planned impacts to the drainage channel. The hydraulics of the flow would not be changed. The road way work is expected to stabilize the edge of the road way and the new curbing will control the direction of surface water runoff. Erosion and sediment controls will be established. To the north west of the culvert and channel there is a small wetland depression (Flags SP-1 to SP-8) set back from the edge of Rye Street some 75 feet. This depression contains saturated soils and seasonally pools water. There are no impacts planned to this area. We note that some of the road work will occur within the regulated setback areas to complete some widening and install new curbs. These improvements are expected to stabilize the road edges and control the runoff of surface water from the paved surfaces. Soil erosion controls will be established along the active road work areas consistent with the plans and details. Additionally the wetland area will be marked with orange snow fencing to make contractors aware of its location and not to be disturbed status. Across from the proposed Distribution Site along the south side of Rye Street is a narrow drainage channel which receives surface runoff through an existing culvert (R-1 to R-10 flags and R-1 A, R-1 B, and R-1 C). This drainage channel has seasonal flow which appears to be mostly a function of precipitation and road runoff. This channel connects to another seasonal wetland and watercourse to the west. Seasonal groundwater infiltration also is observed in lower portions of the channel. The road improvements would remove this culvert and redirect road drainage along the road into a new set of catch basins which would discharge into the adjacent wetland / watercourse area to the west. To remove the culvert and stabilize the edge of the road requires some disturbance of the man-made wetland channel. The disturbance is estimated at some 450 sq.ft and the affected area is shown on Photo 1. This activity is expected to stabilize the area and mitigate erosion presently occurring. 2 To the west of the drainage channel there is an existing 24-inch RCP culvert which crosses under Rye Street. This culvert conveys surface water flows from an upstream wetland / watercourse area to the downstream seasonal wetland/watercourse. These wetlands have a defined stream channel below the north side culvert and a braided stream channel within the upstream side of the road culvert. The wetlands located directly upstream (south side flags RYE-1 to RYE-11, Photos 2, 3, 4 and 5) and downstream (north side flags G� RYST-1 to RYST-10, photos 6, 7, 8, 9 and 10) of the road appear to be highly disturbed based on our field evaluation and shallow soil probes. The soils appear to consist generally of fill layers containing silty loam and sandy deposits. These disturbed soils were included in the wetland delineation because the soil exhibited evidence of saturated surface conditions attributed mostly to ground water seepage. They are bordered along Rye Street by steep, man-made banks which are dominated by invasive vegetation, erosion channels and some debris. Recent work along the road here has included adding some rip-rap stone to stabilize channeled flow patterns from the roadway, placement of sand bags along road atop the banks to mitigate road runoff and resulting scour to the banks. The stream surface water is presently conveyed beneath the road through an existing 24-inch concrete culvert. The proposed improvements would replace the culvert with a new pipe slightly realigned from the existing culvert to improve the hydraulics. This proposed activity would require work in regulated areas including placing clean fill into some wetlands and also the adjacent regulated buffer. We observe that this section of roadway at the stream has existing problems stemming in part from steep embankments and uncontrolled runoff that has resulted in erosion and slope instability. The proposed road work in this area includes improvements to the road base and surface, utility relocation, replacement of the existing culvert with the installation of a new 24-inch RCP culvert to improve drainage, re-grading of the steep banks which border between Rye Street and the lower wetlands / watercourses to lessen the degree of slope and to achieve stabilization of the banks, the addition of catch basins within the roadway to control surface water runoff, installation of a new 15-inch RCP culvert (approximately 65 feet length) to convey surface flow from the new catch basins into the new 24-inch culvert along the north side of Rye Street, and storm-water stabilization at the proposed new 24-inch culvert outlet. Based on the proposed layout the impacts to the disturbed wetland areas would be approximately 800 sq.f1 along the south side and approximately 2,000 sq.ft along the north side and work will also occur in upland review areas. 3 The stormwater from Rye Street to be collected into catch basins and conveyed through a new 15-inch RCP will be pretreated through a stormceptor system installed on the north side as shown on Figure RP2. The disturbance to wetlands for the Rye Street improvements are shown on Figure RP-2. These disturbances will affect disturbed wetland areas presently containing mostly eroded soils which exhibit seasonal groundwater seepage. The placement of engineered fill is needed to re- GZXgrade the north and south road along the culvert crossing to achieve a 2:1 grade. We note that the fill would impact disturbed soils but not the watercourse areas. The watercourse area on the north side begins at the culvert outlet, and the water course along the south generally follows a channel formed near the toe of the embankment. The replacement culvert would generally parallel the existing culvert and maintain the hydraulics of the watercourse. The road improvements and channel culvert replacement will stabilize the road areas proximate to the watercourse and wetlands which presently are impacted by erosion and sedimentation. Mitigation Factors associated with the Rye Street Improvements: • The resetting of the 24-inch road culvert and the re-grading the areas bordering Rye Street and the adjacent wetland and watercourses will result in a final stabilization of the area which presently is adversely impacted by uncontrolled stormwater flows causing erosion scars and an unstable road. • The 2:1 graded slopes will allow seeding and planting of vegetation to create a stable landform with resulting long term benefits to the environment. • The removal of the small 15-inch culvert along the south side of Rye Street across from the proposed facility will reroute uncontrolled surface flow that is presently causing undercutting of the soil surfaces below the culvert. • The plans will provide for appropriate seeding and planting of shrubs and herbaceous plants following the plan on Figure D3. • The majority of the uncontrolled road runoff will be conveyed through a Stormceptor unit installed along the north side of Rye Street to effect pre-treatment of the stormwater. The storm water from the road routed through the Stormceptor unit would connect to a new 15-inch RCP culvert that would be connected into the new 24-inch RCP as shown on Figure RP2. e The Stormceptor system is designed to- provide stormwater treatment through separation of sediment, oil, and grease and other pollutants from the road runoff. These systems provide for higher efficiencies for 4 the removal of TSS-total suspended solids than oil and grit type separators. The use of this technology would provide long term benefits to maintain and enhance water quality over existing conditions. • The existing road embankments which are graded into the existing wetlands contain invasive plants. These plants will be removed as part of the proposed plans. Once the banks are reshaped to a moderate slope -� they will be protected from erosion using Erosion Control Blankets designed for slopes. These blankets would be installed over the finished G� grade and anchored using staples to the subgrade before seeding and planting. • The areas which are stabilized will be monitored as required by the Town for seed and plant survival. In addition the monitoring will include checking and controls for invasive vegetation. • The proposed plantings listed on Figure D3 include only native plants. Other Mitigation Factors associated with the overall project include: • Removal of farm debris which has been found within wetlands, watercourses and upland areas. This removal is underway and has included the removal of unsafe structures (i.e., barns). • Establishing grass land upland habitat along the north end of the distribution facility site. The area will be seeded and mowed annually based on input from the Town. • Mitigating disturbed debris removal areas with erosion fabric, seeding and plating to enhance conditions within and bordering wetlands and watercourses. • Providing stormwater system to include vegetated shelves to provide stormwater treatment mitigation. • A Stormceptor system is proposed at the basin outlet to provide further renovation of the treated stormwater flow. • Grass land, shrub and other vegetation planted as part of the site and other improvements will be monitored for survival and suitability to curb erosion as required by the Town. • Low naturalized soil berms will be added along the perimeter of the farm land and field where needed to mitigate surface runoff into adjacent escarpment channels. 1 5 Attachments: 1.

Stormceptor Information 6 Fact Sheet / Stormwater Technology: Stormceptor (Hydro Conduit, formerly CSR New England Pipe) Revised February 2003 The Stormceptor Fact Sheet is one in a series of fact sheets for stormwater technologies and related perfor- mance evaluations, which are undertaken by the Massachusetts STrategic Envirotechnology Partnership (STEP). A summary of the STEP evaluation entitled, Technology Assessment, Stormceptor CSR New England Pipe, Janu- ary 1998 is provided in this fact sheet.When a more thorough understanding of a system is required,the full Technology Assessment should be reviewed. Copies are available for downloading from the STEP Web site (www.stepsite.org/ progress/reports) or by contacting the STEP Program (Phone: 617/626/1197, FAX: 617/626/1180, email: linda.benevides@state.ma.us). The information in this fact sheet is subject to future updates as additional performance information becomes available. Description/Definition Stormceptor is a prefabricated,underground unit that separates oils,grease,and sediment from stormwater runoff when installed with an existing or new pipe conveyance system.The unit is divided into two cham- bers—a treatment and a flow bypass chamber. During typical storm events,runoff is directed by the inflow weir through a drop pipe into the lower treatment chamber where sediment, oil, and grease are separated from the flow by gravity.The bypass chamber is designed to Bypass weir convey excess stormwater,which overtops the inflow weir,through the system without treatment. Equipment and Sizing lower The on-line Stormceptor units are available in eight sizes ranging from six and twelve feet in diameter with capacities of 900 to 7200 gallons. Since issuing the STEP assessment in 1998,the manufacturer has expanded the Stormceptor product line to include a storm drain inlet (STC 450i)and three units(Models STC 11000,STC 13000,and STC16000).These systems are not included in the STEP evaluation.Users and decision-makers may Figure 1.Stormceptor operation during average flow conditions. require additional field test results and new data for these new systems in order to accept performance ratings, there is a potential for oil and chemical spills. particularly if they are higher than those reported in the STEP technology assessment and this fact sheet.

The roadway improvements are illustrated on plans prepared by Design Professionals and submitted to the Town Wetlands Agency. The proposed roadway improvements include some widening, new base coarse materials, new pavement overlay, adding road curbs, new catch basins and drainage pipes, and utility relocation work. In addition, re-grading is proposed to modify areas along the road including existing embankments which border a section of Rye Street and the adjacent wetlands at an existing stream crossing. Location: Rye Street, South Windsor, CT WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 1.00 NARRATIVE GZA GeoEnvironmental Inc (GZA) has prepared this narrative concerning our assessment/delineation of wetlands and watercourses on the planned roadway improvements along a section of Rye Street in South Windsor. These improvements are proposed to improve an existing section of Rye Street from the planned Aldi distribution warehouse west to the intersection with Sullivan Avenue. We have attached Appendices which provide natural resource information that include a USGS topographic map with GPS points highlighting certain wetlands that are keyed to the function and value forms; a map showing the 100 year floodplain areas and NDDB highlighted areas; and the NRCS soil map. This information is supplemental to the plans by Design Professionals to the Town of South Windsor Planning Department. The section of Rye Street slated for improvements contains an existing paved roadway with drainage features that include rip rap channels, several culverts crossing under the road and utility features. The road section generally borders woodland, open fields, commercial property and a residence. One section of the road crosses over a wetland / stream channel where work is proposed to install new culverts to improve the existing drainage from the paved surfaces. The unnamed stream is formed in a low lying area bordered by moderate to steep slopes. The stream flows from south to north and merges into the Scantic River some 2,000 feet north of Rye Street. State and Local requirements apply to both wetlands and watercourses. Within these requirements wetlands are defined based on certain soil types that exhibit poorly to very poorly drained conditions and/or alluvial / floodplain soils; watercourses are defined by other criteria and may include artificial conditions and temporal, seasonal, non-persistent surface water flow,where a channel or other evidence of flow is present. GZA has reviewed certain natural resource materials to derive information concerning the Site and surrounding areas for wetlands and watercourses. 1.10 NATURAL RESOURCE MATERIALS • NRCS Soil Map - The Soil Mapping indicates the areas along the Rye Street area generally contain moderately well drained Sudbury sandy loam and Ninigret and Tisbury sandy loam to well drained soil types such as Agawam sandy loam and Windsor sandy loam. The mapping indicates that areas bordering steep embankments and escarpments are listed as Udorthents. - 1 - WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 • Town of South Windsor Wetland Map—The Town's wetland map does not depict wetland soils within the level farmland areas of the Site or along the escarpments. The Town map shows wetland soils or watercourses within lowland areas situated along the Scantic River and its tributary streams and floodplains. • CTDEP Natural Diversity Database Map - The NDDB Map highlights areas where State and Federal listed species and significant natural communities may be present. The Map indicates such an area along the western portion of Rye Street. We note that the DEP map extends the highlighted areas to the southwest across Sullivan Avenue. A standard request was made to the State seeking information about the highlighted areas to determine whether the planned land uses would affect the species or natural communities of concern. DEP indicated they have a historic record of State Special Concern Lygodium palmatum (climbing fern) from the general area of South Windsor and a historic record for State Endangered Asio flammeus (short eared owl). The state ecologist has been consulted and we are reviewing the issue with DEP and conducting supplemental field work. To date these species have not been observed. Based on the moist soil habitat requirements for the plant we would expect it is in wetland areas. The plant was not present in the area of the wetlands along Rye Street or in other areas surveyed by GZA. • CTDEP Surface and Groundwater Maps — These maps show the Scantic River and tributary watercourses mapped as GA areas indicating they are suitable for most uses. • Flood Zone FEMA Maps for South Windsor—The FEMA Map show areas of the 100 year flood zone within the watercourses and floodplain areas associated with the Scantic River and its tributaries. The nearest mapped 100 year flood zone is shown some 1,500 feet north from the Rye Street area. • Town of South Windsor GIS Mapping and Wetland Regulations — The wetland regulations were reviewed and the GIS mapping was used to aid in the field work and identifying the potential wetlands and watercourses. 1.20 WETLAND DELINEATION The general limits of the wetland type resources including wetland soils and watercourses that may be defined and regulated by local and state programs were delineated by GZA Soil Scientist Stanley Dynia with GZA wetland ecologist Michelle Manorolla on January 16, 2007. The wetlands and watercourses were defined by numbered flagging and the flagging was surveyed by Design Professionals. The development plans show the flagged wetlands and the regulated upland review area extends 80 feet from wetland or watercourses as defined by the Town of South Windsor regulations. The field program included: - 2 - WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 • GZA conducted field surveys to evaluate upland, wetland, and watercourse conditions and delineate (with wetland flagging) the presence of wetlands and watercourses at the site. Our survey extended on either side of Rye Street to approximately 100 feet in some areas to identify offsite wetland resources which have a regulated setback affecting the Site. • Performed hand excavation of shallow soils to observe soil conditions. • Made observations of the surface and groundwater hydrology and vegetation to assess conditions. The wetland delineation identified: • A seasonal man-made drainage channel with seasonal flow along the north side of Rye Street marked by flags DC-1 to DC-4. This channel receives surface water flow from an open field on the south side of Rye Street. A culvert below the road at this location is to remain. • A wetland depression located on the north side of Rye Street some 50 feet west of the DC flagged channel. This depressional wetland is marked by flags SP-1 to SP- 8. • A man-made and narrow drainage channel is located across from the planned site development area along the south side of Rye Street. The wetland begins at the outfall of a small culvert and has intermittent seasonal surface water flow. This wetland area is marked by flags R-1 to R-10, along its north side and flags RlA, RIB and RIC along its south side. The grading line for the road improvements will affect an area near the road and the existing culvert will be removed. • Wetlands and a stream channel are present bordering Rye Street at a stream crossing. The area north of Rye Street was marked by flags RYST-1 to RYST-16 and the south side by flags RYE-I to RYE-11. The wetland areas adjacent to the road are disturbed and contain invasive vegetation. The wetlands are bordered from Rye Street by steep embankments which are subject to erosion. • There are no mapped 100 year flood zones bordering Rye Street or the planned work areas. The Town of South Windsor Inland Wetland Regulations recognize an "Upland Review" area of 80 feet from wetlands and watercourses based on certain "Regulated Activities" as defined in Section II U. of their regulations. Because of this rule, site work occurring within the upland review areas are regulated and require a wetland permit. The flagged wetlands and watercourses are shown on the plans by design Professionals. - 3 - WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 1.30 PROPOSED PROJECT ACTIVITIES AND REGULATED AREAS The proposed road improvements would require grading along potions of the roadway into wetlands and within the upland review area. The affected wetlands include a manmade drainage channel; and grading to reshape steep embankments along a section adjacent to wetlands where Rye Street crosses a stream channel. In order to reduce the bank steepness, the grading must extend out to form a more gradual slope and a more stable bank. A comprehensive plan for soil erosion and sediment control has been prepared by Design Professionals. Their plan is designed to obviate potential secondary impacts to wetlands from earthwork activities associated with the development. A detailed construction sequence is outlined on the erosion plan which includes a narrative of the project, list of the necessary permits, and.temporary and permanent erosion control measures to be incorporated into the project activities. The erosion plans are provided in the full set of the development plans submitted by Design Professionals. 1.40IMPACTS There are some direct impacts associated with the project that would result in alterations to wetlands in order to properly improve the roadway grades, mitigate existing erosion and to provide for proper drainage. The impacts would occur to disturbed wetland areas that have been altered or created to some degree by antropogenic circumstances. The Contractor will employ soil erosion and sediment controls to mitigate potential secondary impacts from soil erosion. The work schedule will be adjusted to avoid disturbances of soil during rain events. All disturbed areas will be seeded and erosion fabric will be used for certain areas. 1.50 WETLAND FUNCTION AND VALUE GZA has evaluated the wetland areas and we have used the Army Corps of Engineers (ACOE) function and value assessment protocol to evaluate the principle wetland types which are the wetland and stream channel areas where the new culverts are proposed and where the existing embankments will be modified to reduce their steepness and to achieve stabilization. The principal wetland functions related to this area includes flood flow alteration, sediment/toxicant retention, and some wildlife habitat. The planned activities are not expected to alter the functions and values. 1.60 SOIL MAPPING The NRCS maps soils at the site to include mostly well to moderately well drained, upland soils, including Agawam sandy loam, Windsor loamy sand, and Ninigret and - 4 - WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 Tisbury soils. These soils occupy the farmland and adjacent level areas of woodland. Along escarpments bordering the unnamed stream, the mapping lists Udorthents, loamy and very steep. We note that the soil maps are estimated and may not be reflective of actual conditions. 1.70 ALTERNATIVES The project plan was developed to make improvements to the existing section of Rye Street and minimize, to the extent practical, direct impacts to wetlands and regulated upland review areas. This road especially at the crossing of the unnamed stream has been repaired and portions temporarily closed this past year. The area along Rye Street will receive curbing and catch basins to control surface flows and discharges. This measure is expected to reduce the potential for erosion problems that have occurred along this section of the road. In addition the installation of new culverts and the re-grading of embankments are expected to stabilize the land which borders wetlands and a watercourse. The alternative for no action would not result in the needed road upgrades which are essential to support the area use and traffic. Also erosion would likely continue to be a problem. 1.80 MITIGATION The wetlands bordering the stream crossing area contain invasive vegetation that includes Bittersweet, Japanese knotweed and Phragmites as examples. The invasive vegetation may be controlled as part of the Rye Street improvements. These invasive plants presently form some dense stands on the steep embankments bordering the wetlands and within wetlands. The banks also contain debris (e.g. old tires, bottles, etc) that also may be removed as part of the improvements. The improvements are also designed to reduce the steepness of the road embankments that border the wetlands. This measure along with the control of runoff from the road is expected to mitigate erosive conditions that presently exist. - 5 - WETLAND PERMIT APPLICATION Roadway Improvements Rye Street South Windsor, Connecticut GZA File No. 43473 2.00 SUMMARY The wetland/watercourse and upland review areas are regulated resource areas under the Town's Inland Wetland Regulations. The applicant proposes only minor work in disturbed wetlands and some work will occur in the upland review area. Based on the planned improvements we do not expect loss of wetland function or values. We believe the proposed plan will stabilize steep areas of present erosion, better manage the storm- water runoff, and be consistent with the goals of the Town's regulations and planned land uses that will benefit the community. - 6 - APPENDIX A MAPS A.l USGS TOPOGRAPHY WITH GPS COORDINATES Feb 21 07 11 : 45a Design Professionals 860-291 -8757 P- 2 P.O.BOX 1167 425 SUWVAN AVENUE SOUTH WINDSOR,Cr 06074 M PHONE:860.2911755 g■■ FAX:860.291.1:.757 It s www.designprofessionalsinc.com CIVIL & TRAFFIC ENGINEERS I PLANNERS / SURVEYORS / CIS ANALYSTS / LANDSCAPE ARCHITECTS February 21,2007 Mr. Jeff Folger Town of South Windsor 1540 Sullivan Avenue South Windsor,CT 06074 RE: Aldi Distribution Facility Dear Jeff We received your comments dated 2/16/07, and are responding herein. Road Widening Plans 1. The location and amounts of the additional wetland impacts are noted on the Rye : Street road widening plans. The impacts amol.mt to a total of 3,250 S.F. of direct wetland impact. The amount of impact within the 80' upland review limit is 44,000 S.F. of area,and includes the re-construction of Rye Street,with associated grading and drainage work. All fill will be clean fill. 2. Outlet protection(riprap plunge pool) will be added to the plans for catch basin at station 2+29. 3. All catch basins within Rye Street will have the 4' sumps. 4. The plans will be revised to show the slope blankets and appropriate seeding. 5. Jacking of the cross culvert is one option for 1he installation of the cross culvert, though open trench installation is also still an option. If jacking of the cross culvert is done,we would anticipate excavation:nto the existing embankment to provide as short a jacking distance as possible. As such,we do not anticipate any additional wetland impacts associated with the jacking activities. 6. The intent of the culvert replacement is to maintain the existing culvert in operation until the new culvert is complete, and then abandon the existing culvert in place. The culvert will be installed within thc,road fill, and we anticipate minimal de-watering activities. We will include,a dewatering plan and detailed construction sequence. The actual method of ct.lvert replacement will be up to the contractor,and as such there may be some variation in the final methods of construction. The town staff will obviously be involved in the work on the town road. 7. We will investigate the use of chemical flocculent for use in the erosion control plan. Site Plan Portion Feb 21 07 11 : 46a Design Professionals 860-291 -8757 p. 3 : 1. The intent of the design is to flatten out the last rwl of storm pipe prior to AT discharge to 0.5%to reduce velocity. We can also provide a drop in the last manhole structure prior to discharge to further reduce the velocity out of the pipe. ` 2.

The catchbasin at station 2+29 needs outlet protection All proposed catchbasin are required to have 4 foot sumps. The submitted detail shows 2 foot sumps. Slope treatment for road widening plan is not shown. An erosion blanket detail is present but not placed on the plan or included in the narrative. Slope seeding details need to be shown as well. In discussion with the design engineer,the new culvert is proposed to be jacked under Rye Street. Provisions for this activity are not shown on the plans. I anticipate that additional wetland disturbance will be unavoidable. A de-watering plan for the culvert replacement must be shown,as well as a detailed construction sequence. Increase the rate of temporary seeding to 5 lbs per 1000 sgft. There are two different planting plans shown for the detention basin. Please specify the correct one. Decrease the separating distance between seedlings on slope planting plan. Include a chemical flocculent component into the erosion and sediment control plan. cc.

I have reviewed the proposed plan with the following additional comments: There are numerous erosion scars on the site as a result of surface runoff from the farm fields flowing over the highly erodable sand terraces. An analysis of the runoff adjacent to each of the gullies must be done to determine if runoff from the areas not proposed to be paved will continue to impact these areas. The high water table on the site may require that excavations be de-watered to provide a dry work area. Provisions must be made to provide a stable area to pump water into. These must be shown on the plans. The drainage on the site will be altered by the amount of impervious surface proposed. Surface and ground water that currently travels to the western gully will be significantly reduced. What is the current water budget to this gully? How will the diversion of drainage away from this area affect the hydrology to this watercourse? The retaining wall that is proposed to be built adjacent to the western watercourse must be eliminated and fourteen of the proposed truck parking spaces be relocated to other areas on the site. The construction of this wall is reasonably likely to adversely impact the functions of the adiacent watercourse.

As part of the stormwater collection and conveyance system, a storm water detention and water quality basin and storm water outlet system will be constructed. Location: Rye Street: Assessor Map#122 Parcel #1 and Assessor Map#134 Parcel #148 (Project Site) Regulated Affected Area: The wetland and watercourse areas on the project site have been delineated by a GZA Certified Soil Scientist and surveyed onto plans by Design Professionals. The proposed plans for the Distribution center have been prepared by Design Professionals Inc.; Webber Smith Associates Inc.; and Bubaris Traffic Associates. The project site has several narrow, seasonal stream channel wetlands that have formed along the north, south and west escarpments, as delineated and shown on the attached plans, as well as wetlands along the Scantic River. Many of these escarpment wetlands are formed by groundwater seeps on steep terrain. Because these wetlands are sensitive to conditions such as drainage and fill, the development plans were designed to avoid any impacts to these escarpment wetlands, as well as the wetlands at lower elevations. We note that an earlier warehouse layout plan had shown direct wetland impacts for areas of the proposed building and pavement that protruded into one of these wetlands. An alternative plan was developed to obviate direct filling or grading into wetlands. Proposed activities within wetlands or watercourses are limited to the discharge of storm water from a water quality basin into a watercourse and the installation of a 15-inch storm water outlet pipe crossing through a limited section of already disturbed wetland (some 300 s.f.) adjacent to the Scantic River. The outlet pipe route follows an existing filled and graded roadway that provided access from the farm fields to the edge of the river for farm irrigation vehicles and equipment. The installation of the outlet pipes also requires work in upland review areas of some 4,000 s.f. There are no direct wetland losses or permanent adverse impacts to wetlands or watercourses associated with the proposed work. Proposed activities in Upland Review Areas include work (within some 17,000 s.f.) associated with the site improvements related to parking, utility installation, landscaping, paved access, and grading. Potential secondary impacts to the adjacent wetlands from these activities are mitigated by a comprehensive soil erosion and sediment control program shown on Sheets (EI to E5 with details on E6) provided in the Site Development Plans previously submitted to the Town by Design Professionals. A portion of the southwest area of the Site is mapped within a shaded Natural Diversity Area as shown on Figure A (Appendix A). CTDEP has been contacted and staff indicated that a climbing fern was historically reported for the general area. Historic listings also indicated possible short eared owl habitat for the general area. Based on our field work to date, the habitat for the fern appears to fall outside the proposed work areas. We did not observe evidence of the fern within the wetland area proposed for the outlet pipe; and no reported evidence to date has indicated the presence of the owl. A narrative concerning the wetlands and the planned Distribution Center is provided along with supplemental information which includes: Attachments: 1.00 Project Narrative 2.00 Project Summary Appendices: Appendix A Maps A.1 USGS Topography with GPS Coordinates A.2 NRCS Soil Mapping A.3 Natural Resource Plan Figure A Appendix B Function and Values forms WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No.43473 1.00 NARRATIVE GZA GeoEnvironmental Inc (GZA) has prepared this narrative concerning our assessment/delineation of wetlands and watercourses on the planned development Site located on the west side of Rye Street in South Windsor. We understand that the Site comprises two parcels of adjoining land comprising approximately 106 acres. The planned project is for a centralized food distribution center. We have attached Appendices A and B, which provide natural resource information that include a USGS topographic map with GPS points highlighting certain wetlands that are keyed to the function and value forms; a map showing the 100 year floodplain areas and NDDB highlighted areas; and the NRCS soil map. This information is supplemental to the comprehensive development plans previously submitted by Design Professionals to the Town of South Windsor Planning Department. The majority of the Site is open, level land historically used for farming and used most recently for vegetable crops such as corn. The perimeter of the site includes Rye Street bordering the east side; terrace escarpments with steep grades along the north that descend towards two watercourses, the Scantic River and its tributary, Dry Brook; sloping terrain on the west side that is moderate and descends towards the Scantic River and its floodplain; and escarpments with moderate to steep slopes on the south side that desend towards an unnamed tributary stream which flows west into the Scantic River. The Scantic River is a tributary to the Connecticut River, which is located some 5,000 feet west of the Site. State and Local requirements apply to both wetlands and watercourses. Within these requirements wetlands are defined based on certain soil types that exhibit poorly to very poorly drained conditions and/or alluvial / floodplain soils; watercourses are defined by other criteria and may include artificial conditions and temporal, seasonal, non-persistent surface water flow, where a channel or other evidence of flow is present. GZA has reviewed certain natural resource materials to derive information concerning the Site and surrounding areas for wetlands and watercourses. 1.10 Natural Resource Materials • NRCS Soil Map - The Soil Mapping indicates the level farmland areas generally consist of well to moderately well drained soils. In general, these soils have a sandy loam upper horizon underlain by fine to medium sands. In the South Windsor area, the well drained surficial soils are generally underlain by dense - 1 - WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 silty clay. The wooded sloping escarpments generally show this profile with a shallow surficial layer of sand/sandy loam underlain by dense silty clay. • Town of South Windsor Wetland Map—The Town's wetland map does not depict wetland soils within the level farmland areas of the Site or along the escarpments. The Town map shows wetland soils or watercourses within lowland areas situated along the Scantic River and its tributary streams and floodplains. • CTDEP Natural Diversity Database Map — The NDDB Map highlights areas where State and Federal listed species and significant natural communities may be present. The Map indicates such an area along the south/southwest side of the Site bordering the steep escarpments and an unnamed stream. We note that the DEP map extends the highlighted areas to the southwest across Sullivan Avenue. A standard request was made to the State seeking information about the highlighted areas to determine whether the planned land uses would affect the species or natural communities of concern. DEP indicated they have a historic record of State Special Concern Lygodium palmatum (climbing fern) from the general area of South Windsor and a historic record for State Endangered Asio flammeus (short eared owl). The state ecologist has been consulted and we are reviewing the issue with DEP and conducting supplemental field work. To date these species have not been observed. Based on the moist soil habitat requirements for the plant we would expect it is in wetland areas. As part of the development plan, wetland areas are being avoided, except for a small area of wetland disturbance to install an outlet pipe from a stormwater basin. The plant was not present in the area of the planned pipe location. • CTDEP Surface and Groundwater Maps — These maps show the Scantic River and tributary watercourses. Based on our understanding of the Site area, portions of the Scantic River and a small portion of Dry Brook are located within the northwest area of the Site; with sections of the Scantic River also present in the western area of the Site. • Flood Zone FEMA Maps for South Windsor—The FEMA Map show areas of the 100 year flood zone within the watercourses and floodplain areas associated with Dry Brook, the Scantic River and the unnamed stream to the south. The 100 year flood elevation is approximately at elevation 32 feet. Portions of the flood zone appear to occupy low areas on the west / northwest areas of the Site at the toe of the escarpments. The upper farm land area is situated near elevation 80 feet. • Town of South Windsor GIS Mapping and Wetland Regulations — The wetland regulations were reviewed and the GIS mapping was used to aid in the field work and identifying the escarpments and approximate property lines. 1.20 Wetland Delineation The general limits of the wetland type resources including wetland soils and watercourses that may be defined and regulated by local and state programs were delineated by GZA Soil Scientist Stanley Dynia,mainly during the spring and summer of 2006. The wetlands -2 - WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No.43473 and watercourses were defined by numbered flagging and the flagging was surveyed by Design Professionals. The development plans show the flagged wetlands and the regulated upland review area of 80 feet from wetland or watercourses as defined by the Town of South Windsor regulations. The field program included: • GZA conducted field surveys to evaluate upland, wetland, and watercourse conditions and delineate (with wetland flagging) the presence of wetlands and watercourses at the site. Our survey extended offsite to approximately 100 feet in some areas to identify offsite wetland resources which have a regulated setback affecting the Site. • Performed hand excavation of shallow soils to observe soil conditions. • Made seasonal observations during 2006 of surface and groundwater to assess the hydrologic conditions. The wetland delineation indicated: • The upland farmland areas did not contain wetlands or watercourses. • Wooded areas along the north and west side of the Site where the grade is similar to the farmland did not contain wetlands or watercourses. • Temporal wetland soils and water courses are present along the terrace escarpments bordering the north, south and west margins of the Site. These wetlands and temporary watercourses are formed in natural eroded channel shaped landforms that are saturated and exhibit surface and groundwater discharge flow, with groundwater being the primary hydrology. Wetland flags were located to mark these areas. • Wetlands are also present bordering the western margins of the Site and include the eroded channel landforms and wetland soils of the floodplain; these areas were marked with flags and surveyed. • F000dplain wetlands border the Scantic River and include lowland areas along the river's edge. These wetlands generally mimic the 100 year flood zone as mapped by FEMA. The Town of South Windsor Inland Wetland Regulations recognize an "Upland Review" area of 80 feet from wetlands and watercourses based on certain "Regulated Activitys" as defined in Section II U. of their regulations. Because of this rule, site work occurring within the upland review areas are regulated and require a wetland permit. The flagged wetlands, watercourses and regulated upland review areas are shown on the previously submitted development plans. - 3 - WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 1.30 Proposed Project Activities and Regulated Areas The proposed project includes the installation of an outlet pipe from a water quality basin that will cause temporary disturbance of some 300 s.f. of inland wetland bordering near the Scantic River, to which the pipe will discharge. The crossing area is along an existing farm road, created by filling wetlands some years ago. In addition, the installation of the storm water outlet pipe will result in short term disturbance within the regulated upland review areas of some 4,000 s.f. The construction of the 468,595 square foot distribution facility, offices, appurtenant parking facilities for tractor trailers, and employee vehicles, paved parking, access drives, the storm water quality basin, grading, a retaining wall, landscaping berms and utility installations,will affect disturbance within some 17,000 s.f of regulated upland areas. There is no direct filling or grading of wetlands for construction of the facility as proposed A comprehensive plan for soil erosion and sediment control has been prepared by Design Professionals. Their plan is designed to obviate potential secondary impacts to wetlands from earthwork activities associated with the development. A detailed construction sequence is outlined on the erosion plan detail sheet Figure 6, which includes a narrative of the project, list of the necessary permits, and temporary and permanent erosion control measures to be incorporated into the project activities. The erosion plans are provided in the full set of the development plans submitted by Design Professionals. 1.40 Impacts There are no permanent impacts associated with the project that would result in permanent loss of wetlands or watercourses. The Contractor will employ soil erosion and sediment controls to mitigate potential secondary impacts from soil erosion. The work schedule will be adjusted to avoid disturbances of soil during rain events. All disturbed areas will be seeded and erosion fabric will be used for certain areas. 1.50 Wetland Function and Value GZA has conducted several site visits to evaluate the areas and has used the Army Corps of Engineers (ACOE) function and value assessment protocol to evaluate the principle wetland types including those in the temporal wetlands formed in the north and south escarpments, the floodplain wetlands along the Scantic River and its tributaries, and the Scantic River. ACOE forms are attached for reference in Appendix B and the areas are keyed to the points shown on the attached USGS topographic map section. The principal wetland functions described for the escarpment wetlands, though limited because of the relatively small area within a large watershed, are ground water discharges to surface waters and wildlife habitat. The other related limited function and value is nutrient removal and sediment toxicant removal as a result of the attenuation of runoff from nearby agricultural fields. -4- WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels#1 and #48 South Windsor, Connecticut GZA File No.43473 The principle function and values for the floodplain wetlands are described to include flood flow alteration, sediment/toxicant retention, and wildlife habitat. The Scantic River principle functions are described as flood flow alteration, fish habitat, and wildlife habitat. Based on our understanding of the proposed project the wetland functions and values will not be changed or adversely affected as a result of the development. 1.60 Soil Mapping The NRCS maps soils at the site to include mostly well to moderately well drained, upland soils, including Agawam sandy loam, Windsor loamy sand, and Ninigret and Tisbury soils. These soils occupy the farmland and adjacent level area of woodland. Along the north, south, and west escarpments, the mapping lists Udorthents, loamy and very steep. The mapped wetland soils are confined to low lying areas proximate to the floodplains and the Scantic River. These soils include the Limerick soils, poorly drained silty soils on floodplains; Saco silt loam, frequently flooded very poorly drained soils; and Fluvaquents-Udifluvents complex, frequently flooded. The lowland wetland soils along the floodplains mapped by NRCS and the Town Map are found generally consistent with our field observations and delineation. We note that the temporal wetlands delineated by GZA along the escarpments are not shown on the NRCS soil or Town wetland map. We note that the soil maps are estimated and may not be reflective of actual conditions. 1.80 ALTERNATIVES The project plan was developed to minimize, to the extent practical, direct impacts to wetlands and regulated upland review areas. Previous plans for the site by Lally Engineers had proposed fill placement into a section of the escarpment wetlands. The present development plans avoid wetland fills. We also held site meetings with the design team to review the wetland locations and to select appropriate locations for the building and for stormwater controls. As a result, the development plan places the key components outside of the actual wetlands or watercourses with the exception of a 15 inch outlet pipe that will cross the wetland near the Scantic River disturbing some 300 s.f. of wetland. The pipe layout follows along an existing farm road, which historically was created through grading that had disturbed the wetlands. Other areas for the discharge outlet were reviewed in the field. These included several locations along the south / west escarpments; however because of the nature of these wetlands,which have formed in eroded channels, the areas were avoided. - 5 - WETLAND PERMIT APPLICATION Distribution Facility Rye Street Parcels #1 and #48 South Windsor Conne cticut GZA File No. 43473 2.00 SUMMARY The wetland/watercourse and upland review areas are regulated resource areas under the Town's Inland Wetland Regulations. The applicant proposes only minor work in wetlands and some work will occur in the upland review area. There are no permanent impacts that would result in the loss of wetland function or value. We believe the proposed plan within the industrial zone is consistent with the goals of the Town's regulations and will benefit the community. - 6 - APPENDIX A APPENDIX A.1 USGS TOPOGRAPHY WITH GPS COORDINATES MapCard - Print your custom map Page 2 of 2 N 0 1000 Ft 4 http://www.mapcard.com/maps/print local.asp?print=l&scale=2.43 84&layer=DRG&lay... 12/14/2006 APPENDIX A APPENDIX A.2 NRCS SOIL MAPPING SOIL SURVEY OF STATE OF CONNECTICUT Rye Street South Windsor CT MAP LEGEND MAP INFORMATION i Soil Map Units • Cities Source of Map: Natural Resources Conservation Service 0 Detailed Counties Web Soil Survey URL: http://websoilsurvey.nres.usda.gov Q Detailed States Interstate Highways Coordinate System: UTM Zone 18 Roads Soil Survey Area: State of Connecticut -i— Rails Spatial Version of Data: 3 Water Soil Map Compilation Scale: 1:12000 Hydrography Oceans AYAYAYAY Escarpment,bedrock vnvnvnv.

The debris was placed along upland ridges of the property, and as a result of wind and soil/water movement, some debris has been spread into certain wetland/watercourse areas. The planned removal / clean-up of the old debris will therefore require debris removal from the wetlands / watercourses areas and their respective upland regulated areas bordering within 80 feet of wetlands and watercourses. Debris present in upland areas that is outside the Regulated Area will also be addressed. The wetland and watercourse areas have been delineated by a GZA Certified Soil Scientist and surveyed onto plans by Design Professionals. The attached Figure 1 shows the location of the two primary debris areas planned for clean-up. The objective of this planned work effort is to effect removal of surficial debris throughout the site. Debris thicknesses generally range from ground surface only to four feet thick, based on test pit observations. In addition to the two primary areas, we note that there are isolated areas of scattered debris such as old tires and empty containers. There are also several abandoned vehicles at the property to be removed along with miscellaneous abandoned equipment and demolition and total removal of the old sheds and the house. Based on our assessment of the work areas and the nature of the debris, there are no direct wetland losses or permanent impacts to wetlands or watercourses associated with the proposed work. A narrative for the debris removal is provided along with information which include the following: Attachments: 1.00 Project Narrative 2.00 Project Summary Appendices: Appendix A Maps A.1 Debris Removal Plan Figure 1 by Design Professionals A.2 USGS Topography Map with north and south debris areas A.3 NRCS Soil Mapping A.4 Natural Resource Plan Figure A A.5 Assessment Plan with test pits in north and south debris areas Figure B Appendix B Photographs Appendix C Test Pit Logs Appendix D Function and Values forms WETLAND PERMIT APPLICATION Removal of Farm Debris Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 1.00 NARRATIVE The proposed debris removal will be done voluntarily with the objective to remove historic, farm related debris from the project site. The property containing the debris consists of two adjoining parcels that are planned for eventual re-development for a commercial warehouse. The plan for debris removal was discussed preliminarily with Town Staff. Several figures in Appendix A are provided to show the general location of the debris areas. The debris planned for removal is generally present near the ground surface with minimal soil cover. Several photos in Appendix B provide a representative depiction of the debris areas along with pictures showing the shed, other debris and the house, which are also to be removed. A significant amount of the debris in the north and south areas is on top of the ground surface and will be collected by manual pick up. The debris materials along some upland / wetland slopes will require mechanical lifting for removal using an excavator bucket or crane type boom extensions. The removed debris will be stockpiled within designated upland areas pending off-site disposal / re-cycling. For the demolition and removal of the old sheds and the house, heavy equipment will be used to raze and cleanup these structures. We note that portions of certain structures fall partly within the upland review area as shown on Figure 1. GZA has preformed a limited Phase II environmental study of the two primary debris areas which included the installation of shallow test pits 1 through 6 supplemented with shallow hand auger borings. The test pit locations are approximately shown on Figure B. GZA field staff observed the soil conditions within the test pits and hand augured. borings. They also preformed environmental field screening of the soil and collected representative soil samples for laboratory testing. The soil conditions underlying the two primary debris areas did not exhibit environmental impacts related to the debris. Certain soil samples contained pesticides at low levels, below Connecticut Remediation Standard Regulations criteria. The low levels of pesticides in certain shallow samples are attributed to agricultural runoff. The approximate locations of the two primary areas in relation to the nearby wetlands and regulated areas are shown on Figure 1. One of the primary debris areas is located south west of the existing house (photo 5). Test pit 1 was installed in this area. This area has approximately 3 to 4 feet of soil mixed with debris. The debris area here is located within an upland review area bordering an area of wetland soil and an associated temporal, narrow stream channel. The temporal stream is fed by groundwater seeps and is also - 1 - WETLAND PERMIT APPLICATION Removal of Farm Debris Rye Street.Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 recharged by rainfall. The channel flows down the escarpment slope and merges with an unnamed steam. Temporary erosion controls (hay bales and silt fencing) are proposed between the work area and the lower elevation wetlands. The disturbed areas would be covered with mulch and/or erosion fabric fastened to the ground with staples, until the area is seeded in the growing season. There are no direct impacts proposed within the wetlands and the erosion controls, mulch and erosion fabric are proposed to mitigate against potential secondary impacts from the disturbed upland soil during the short term debris removal work. Another area, shown on Figure 1, is located near the north property line. The debris here is mostly surficial and extends along a terrace ridge line (see Photos 1 and 2). Test pits 2, 3, 4, 5, and 6 were installed here. The bordering lower elevation wetlands include poorly drained, seasonally saturated soils adjacent to a narrow and shallow, temporal stream channel. The stream is intermittent and the soils are saturated seasonally by groundwater seepage and are also recharged by rainfall. The upland soil here contains topsoil strata underlain by sand and / or sandy loam overlying a dense silt and clay layer. This dense layer causes perched groundwater, which follows the top of clay and results in seepage discharges along the toe of the slope and into the stream channel. Most of the work here will involve work in the upland review area, however some of the debris is within the flagged wetland soil area. As illustrated by photo 1, some of the debris items are on the surface within the stream channel. These items would be removed by manual pickup. For access and to allow removal of certain debris along the ridges and slopes, some vegetation cutting will be required within the uplands and upland review area, with limited trimming within the wetlands. Based on discussions with Town staff, trees that may require cutting within the wetland would be cut some 2-4-feet above the ground to allow rejuvenation of the vegetation. By leaving the stump in place, the roots and surrounding soil will not be disturbed. Erosion controls (hay bales / silt fencing) will be installed as appropriate between the work areas subject to temporary disturbance and the nearby lower wetlands and stream channel. Temporary disturbances of upland and wetland soils resulting from debris removal will be mitigated with mulch with appropriate plantings and seeding during the growing season and erosion fabric will be stapled in place as needed until seeding and planting occurs. The type and number of plantings would be coordinated with input from Town Staff. During the debris clean-up, an environmental engineer would be present to help coordinate the debris removal, stockpiling and disposal / re-cycling. The engineer will monitor environmental conditions and document the clean-up work and also check the temporary erosion and sediment controls (i.e. hay bales / silt fence) to be installed by the contractor between any disturbed soil surfaces and nearby wetlands or watercourses that may be present. The engineer will also observe and help coordinate the restoration of - 2 - WETLAND PERMIT APPLICATION Removal of Farm Debris Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 disturbed areas by the Contractor through the installation of erosion fabric, mulch, seed and plants. 1.30 TEMPORARY IMPACTS There are no permanent impacts proposed to wetlands, watercourses or upland review areas. We anticipate short term affects from accessing debris areas and from removal of the debris is some areas. The Contractor will employ soil erosion and sediment controls to mitigate potential secondary impacts from soil erosion. The work schedule will be adjusted to avoid disturbances of soil during rain events. A GZA engineer will be present during the work activities to observe and monitor conditions. Thereafter, we will conduct monitoring of the work areas to mark the progress of stabilization and re-vegetation of disturbed areas. 1.50 FUNCTION AND VALUE ASSESSMENT GZA has conducted several site visits to evaluate the areas and has used the Army Corps of Engineers (ALOE) function and value assessment protocol to evaluate the nearby wetlands proximate to the north and south debris areas. The ACOE forms are attached for reference in Appendix D. The principal wetland functions, though limited because of the relatively small area within a large watershed, are ground water discharges to surface waters and wildlife habitat. We note that the primary debris removal areas and all existing buildings are located outside the 100 year flood zone as mapped by FEMA. The other related limited function and value is nutrient removal and sediment toxicant removal as a result of the attenuation of runoff from nearby agricultural fields. CTDEP has reported possible presence of a plant of special concern (climbing fern) from the general area of South Windsor. This fern has not been observed at the Site during our field visits. The proposed clean-up work is designed to enhance the present function and values of the wetland. 1.60 SOIL MAPPING The wetland areas near the planned primary work areas for debris are very similar in their formation and hydrology. In both areas, there is a narrow stream channel formed within an eroded valley cut into the underlying clay. The stream channels are bordered by some poorly to very poorly drained wetland soils and are formed along the escarpments. The intermittent watercourses formed within the escarpment channels are recharged by groundwater seepage and rainfall runoff. Hydrophilic plants such as Skunk Cabbage (Symplocarpus foetidus) are found within the channels. These are obligate wetland plants indicating near surface saturation during the early part of the growing season. - 3 - WETLAND PERMIT APPLICATION Removal of Farm Debris Rye Street Parcels #1 and #48 South Windsor, Connecticut GZA File No. 43473 The NRCS soil map, which is in Appendix A, maps soils at the site to include mostly well to moderately well drained, upland soils, including Agawam sandy loam, Windsor loamy sand, and Ninigret and Tisbury soils. These soils occupy the farmland and adjacent level area of woodland. Along the north, south, and west escarpments, the mapping lists Udorthents, loamy and very steep. The mapped wetland soils are confined to low lying areas proximate to the floodplains and the Scantic River. The small stream channels formed on the escarpments, that were delineated in the field as wetlands or watercourses, are not shownn on the NRCS soil or Town wetland map. We note that the soil maps are estimated and may not be reflective of actual conditions. 1.80 ALTERNATIVES The plan submitted was based in part on preliminary staff input. Alternatives to the proposed wetland restoration/maintenance work as proposed may include: • No Action - This alternative is not considered an appropriate measure because the debris would remain in place. 2.00 SUMMARY The wetland/watercourse and upland review areas are regulated resource areas under the Towns Inland Wetland Regulations. The applicant proposes to perform maintenance work to clean up debris with supplemental mitigation work to enhance disturbed upland and regulated areas with mulch, seeding and plants, should disturbances occur. There are no permanent impacts or loss of wetland function or value anticipated. We believe the proposed plan is consistent with the goals of the Town's regulations and will benefit the environment by removing unsightly debris and a potential source of pollution We trust the Commission will find the application materials complete and satisfactory to issue a permit to allow the cleanup of the old farm debris. - 4 - APPENDIX A A.1 DEBRIS REMOVAL PLAN FIGURE 1 BY DESIGN PROFESSIONALS 11 �/ IIIIII I Itli Ilia II 1 1 1 1\I (1 ' sa / � \ / op (i( II I/I wl Illll jlllll II(/ III��I (� ` \ Nk 1\ Xi OU P v 03 om c i xi l x /� 111// •� \\\ / °I xI /y7( qiz / ` o / • J 1 I 1 I / 1 1b 1 1 1t I � ' wm. a+wn � x NPa MP xw \ \ xw N lx. \ 1 M ,..» / \ \ VFW x— i xw \ F\ NIX N DEBRISSTALLS ILTI FENCES \\\\ \ xu XW 'N\ DOWN SLOPE OF AR l xw STA N� — /'-`� 'D"Af lt'o of c rl' 62s PCN 9)Cur ' ��/ r I + r \ \ \ \ x xu 3?- Debris Removal Notes. x 1.

Folger—Environmental Planner/Conservation Officer Date: December 27, 2006 Re: Appl. #06-60P Review of the proposed Aldi's Distribution facility at 295 Rye Street. Plans dated 12/01/06 The project is to seek approvals and create a 500,000-sqft retail grocery store distribution facility, and tractor/trailer parking. Stormwater is proposed to be discharged onto an retention/water quality basin, which will empty into the Scantic River. Proposed activity within regulated areas equal 300 sqft, proposed activity within the URA equal 2 1,100 sqft. Site: The site is located in the Scantic River watershed. The site is comprised of a lot totaling 106 acres. Approximately 23.4 acres of impervious surface is proposed. The site is a combination of a 45+acre, flat open field surrounded on three sides by a hardwood deciduous forest with steep slopes leading to the floodplain and main channel of the Scantic River. The current use of the active portion of the site is production agriculture. There are several dirt access roads leading into the site from Rye Street. One of these extends down one of the slopes to the river. This path was used for irrigation piping and a pump. Surface runoff exited the farm field in a number of places along the perimeter slopes. Due to the highly erodable nature of the soils in the area, each exit point resulted in a moderately steep gully. The gullies are fairly stable at this point in that the sides are vegetated with active cutting occurring only at the bottom where there is semi constant water flow from surface and ground water seeps. The hardwood forest that rings the Ag field extends down the terrace slopes to the Scantic floodplain. The forest is comprised of mature oak, ash, hickory, and beech trees in the overstory. The understory is sparse in shrub growth due to the dense canopy above. Ferns and shade tolerant forbs are present on the forest floor. All of the trees present provide hard mast(nuts) as wildlife food. This area would be considered high quality wildlife habitat due to the food available and the proximity to the river bottom. The gullies serve as wildlife corridors supplying water and cover to wildlife moving through the area. Regulated areas on the site consist of the main stem of the Scantic River and its southern floodplain. This portion of the river contains meanders in the sandy soils present. The floodplain adjacent to the subject site ranges from 30 to 100 feet wide. The stream channel width averages 10 to 20 feet with a depth of 3 to 6 feet. The channel bottom is comprised of medium to fine sands. The streambed is active with sedimentation reacting to seasonal changes in flow. Wetlands on the site appear to be accurately identified. The floodplain would be classified as a wooded wetland type. Red maple, Cottonwood, and Silver maple dominate the over story. The shrub understory vegetation is limited due to the dense canopy, but is present. Emergent vegetation(skunk cabbage, false hellebore, and jack-in-the-pulpit) is quite thick during the growing season. The wetland boundary starts roughly at the toe of the slope. Each of the erosion scars consists of a watercourse and adjacent hydric soils. The flow within these watercourses is dependent on the groundwater supply in the Ag field. The watercourses are rarely dry; this occurring only in drought years. Besides the main channel of the river, these seep areas are a source of moisture for plants in an otherwise well drained soil, and can create"micro environments". Impacts: The soils listed on the site report are Windsor Loamy Sand(WuA) 0 to 3% slope Agawam Fine sandy loam(AgA) 0 to 3% slopes and Terrace Escarpment(Te)on the slopes leading down to the floodplain. Perimeter erosion controls will be adequate to contain sediments from construction activities on the flat portion of the site. The terrace escarpment soils are notorious for significant slope failures and rapid erosion when water is introduced to them either surface or subsurface. Hundreds of thousands of dollars have been spent repairing property damage due to construction activities on these slopes both in South Windsor and throughout the Scantic watershed. A retaining wall is proposed to be constructed on these slopes to accommodate a sanitary sewer line and approximately twenty parking spaces. This portion of the plan should be abandoned and the structures should be relocated to avoid this area. It is my opinion that there is a high probability that constructing the proposed retaining wall will result in unreasonable sediment impacts to the adjacent watercourse which can be avoided. The sedimentation of the watercourse channel would reduce its effectiveness to transport ground water, cause sedimentation to receiving waters which would negatively impact aquatic organisms present in these waters. Based on the steepness of the slope, the instability of the slope material, and lack of detail on the construction procedure, there is a high likelihood that the adjacent wetlands will be negatively impacted by the proposed activity. Portions of the forested area along the northern property boundary are proposed to be cut even though there is no development associated with them. This arbitrary removal of productive wildlife habitat should be avoided. Stormwater: The stormwater management consists of a series of catchbasins piped to a large retention basin which would ultimately discharge to the main channel of the Scantic River. The catchbasins are supplied with deep sumps for initial sediment storage. Trap hoods should be fitted within these structures to capture floatables close to the source. Due to the very large amount of impervious surface on the site the treatment train should also be fitted with a high efficiency gross particle separator prior to the retention basin. The large storage capacity of the retention basin and amount of permanent pool area that will exist, in combination with the above mentioned structures should provide a very high degree of pollutant removal. The very small outflow orifice from the basin will meter out only small amounts of accumulated stormwater. This should address increased volume impacts to the Scantic River channel. Mitigation: Mitigation in the form of wildlife habitat plantings has been proposed for the wetland disturbances. Transformation of the existing Ag field into a warm season grass meadow is also proposed in the remaining upper field area. A management plan should be prepared to maintain the integrity of the planted meadow. The wetland ecosystem that will develop within the basin as a result of the presence of water and proposed plantings with provide diversity on the site. 02/06/2007 TUE 10: 07 FAX 860 644 7280 South Windsor Town Hall 0001 ********************* *** FAX TX REPORT *** ********************* TRANSMISSION OK JOB NO. 2988 DESTINATION ADDRESS 98606431180 PSWD/SUBADDRESS DESTINATION ID Journal Inquirer-Legal ST.
