A location map is included in the appendix. The overall property is approximately 60 acres in size. A smaller parcel for a new school is proposed to be created by subdivision of this parcel. The school site is located west of Long Hill Road, south of Chapel Road and north of Connecticut Interstate 291. It is proposed to be 14.35 acres in size with 436.16' of frontage on Long Hill Road and 414.60' of t ; frontage on Chapel Road. The length of the property line along I-291 is proposed to be approximately 630 feet. The focus of this report pertains to the 14.35 acre school parcel and it will be referred to as "the site"in this report. No wetlands, watercourses or vernal pools exist on this site. Therefore,the impacts of the proposal will consider potential effects on these features on the remaining adjacent land to the west. z f The purpose of this report is two fold. The first is to describe the general site environmental condition and features such as topography,vegetative cover, upland and wetland soils, surface and ground water conditions,vernal pools as well as the details of the site investigation. Many site visits were conducted to document these features. Part of the site investigations included looking for the potential presence of Barratt's sedge (Carex barrattii-Endangered)and Clustered sedge (Carex cumulata- Threatened). These species are known to have colonies in the general area. The site investigation also included investigating the potential presence of habitat suitable for the Pine Barrens Tiger Beetle(Cicindela Formosa generosa—Special concern species). The second purpose of this report is to evaluate the potential impacts of the proposed activities on wetland functions,vernal pools and groundwater conditions. This will include the potential impacts of site grading,paving, erosion and sedimentation, stormwater management and groundwater control on these resources. LJ Megson&Heagle Civil Engineers&Land Surveyors,LLC i Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT j Page 2 Site Environmental Conditions and Features General The site is bordered by two town roads and a state highway. Approximately two thirds of the site is vegetated with mature tree growth and one third with early succession growth over an old cleared field. This area is a mixture of grasses, thick scrub shrub and small trees. Several old gullies are present on the western portion of the site which probably was the result of erosion when the overgrown field area was unstable. An area exists in the far westerly portion of the site which appears to be an old excavation pit. Residential houses which front on Chapel and Long Hill Roads border a portion of the northerly and easterly boundaries. Topography The site has a significant amount of topographic relief in an easterly/westerly direction with the steeper slopes being along the westerly side. The slope faces to the west. The highest point of the site is in the easterly most point of the site on Long Hill Road and is at elevation 139. The lowest point is the bottom of the old excavation pit and is at elevation 73. The average slopes in the easterly two thirds of the site range from 4 to 7%. The average slopes along the westerly side generally range from 10 to 20%. Two notable topographic features exist on the site. One is the presence of several significant ravines on the steeper portions. These are presently stable but appear to have been created by erosion in previous years. These most likely were created when the site was not vegetated completely. The history of the site was not researched but it may have used for agricultural purposes at some point. An old foundation and concrete barn piers were noticed during site visits. The other notable feature is what appears to be an old excavation pit located on the westerly boundary of the site. It is approximately 60 to 150' wide, 300' long and 10 feet deep. It has not been active for a number of years as large trees are located in the bottom and along the sides. Vegetation The vegetation of the site is divided into two distinct areas. Approximately two thirds of the site consists of mature canopy tree growth composed of mostly medium to large trees. The dominant species are maple, oak and hickory. The less dominant species include beech,pine, cottonwood, birch, elm, ash, sassafras, a } Megson&Heagle Civil Engineers&Land Surveyors,LLC ti i l l Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT Pape 3 cherry and iron wood. An extensive tree survey was conducted and is depicted on the existing conditions map that is part of the site plans. The other one third of the site is vegetated with species common in an early succession/old field environment. This vegetation includes grasses, multi floral rose, several maple saplings, and dense scrub shrub growth. The area is very thick and overgrown with some sections being impenetrable. This area is located in the southerly portion of the site and is bordered to the south by the I-291 corridor. Surface and ground water conditions The surface water of the site flows from east to west in a sheet flow and small channel flow manner. No watercourses exist on the property but several medium to large gulleys were observed on the western half of the site. These were most likely the result of erosion when the site was cleared several years ago. They do not appear to convey any significant amount of surface water currently based on the onsite visits conducted during this spring and summer. The direction of ground water flow under the site is presumed to be from east to west. This is based on the topography. The site exhibits a typical topo drainage sequence with the well drained soils on higher elevations of the site,moderately well drained soils on a majority of the site and in the middle of the slope, and the poorly drained soils offsite and at the bottom of the slope. Ground water levels fluctuate seasonally. Groundwater depths on this site were observed to be relatively shallow in the spring in the wetter areas. Groundwater depths appear to be deeper in the dryer season. Vernal pools No vernal pools are located on the site. However, potential vernal pools exist to the west on the remaining land. Vernal pool species were observed in some of these pools during the spring. The closest of these potential pools is located approximately 280 feet to the west of the proposed property line. A map is included in the appendix depicting approximate locations of these. Additional pools are potentially located farther west. These pools were not studied in detail. No direct surface water connection is apparent in the field between the site and any of the potential vernal pools. Runoff from the site flows down the steeper slopes but then infiltrates near the toe of the slope. A significant area around the vernal pools has a relatively flat topography isolating them from the site in terms Megson&Heagle Civil Engineers&Land Surveyors,LLC F� t � Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT Pa e 4 f of surface runoff. These pools appear to be primarily supported by groundwater with a small contribution of surface water from their immediate surroundings. Floodplain No areas of the site are designated as being within the 100 or 500 year floodplain on the Flood Insurance Rate Map for this area. State Listed Species A request was made to the CT DEEP Natural Diversity Data Base for a Review of State Listed species. A copy of their response is included in the appendix. Their records indicate an extant population of a species of special concern was within the vicinity of the project. This is the Pine Barrens tiger beetle. As stated in the response letter this beetle occupies blowouts and sand plains of dry-xeric, loose shifting sands,without water that are sparsely vegetated, such as Pine Barrens. As also stated in the letter the project will not conflict with this species. Our visits to the site confirm no suitable habitat exists on or in close proximity to it. At the suggestion of the Senior Environmental Planner,Jeff Folger,the site was also carefully surveyed for the possible presence of Barratt's sedge(Carex barrattii-Endangered)and Clustered sedge(Carex cumulata-Threatened). These species are known to have colonies in the general area. Neither of these was found to be located on or in close proximity to the site. Soils General All of the soils on the site are upland soils. A majority of them consist of glacial moraine deposits. No wetland soils are present on the site. However, wetland soils do exist approximately 70' west of and down gradient from the site. A majority of the soils are undisturbed with the exception of the old excavation area along the proposed westerly boundary line. Areas of previous erosion are also present on the site in several areas. Upland Soils According to the NRCS Web Soil Survey approximately 80%of the soils of the site consist of the Rainbow series. The Rainbow series are moderately well drained loamy soils formed in silty mantled lodgement till. The soils are deep to bedrock and moderately deep to a densic contact. They are nearly level to strongly sloping soils on till plains,hills and dramlins. Saturated hydraulic conductivity is Megson&Heagle Civil Engineers&Land Surveyors,LLC 2 �J Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT } Pate 5 moderately high or high in the surface layer and subsoil,and low to moderately high in the dense substratum. The NRCS mapping depicts the remainder of the site to consist of soils in the Haven, Enfield and Windsor series. The Haven series are very deep,well drained soils formed in loamy over sandy and gravelly outwash. They are nearly level through moderately sloping soils on outwash plains,terraces, and water-sorted moraine deposits. Saturated hydraulic conductivity is moderately high or high in the mineral solum and very high in the substratum. The Enfield series consists of very deep well drained loamy soils formed in a silty mantle overlying glacial outwash. They are nearly level to sloping soils on outwash plains and terraces. Saturated hydraulic conductivity is moderate or moderately rapid in the surface layer and subsoil and rapid or very rapid in the substratum. The Windsor series consists of very deep excessively drained soils formed in sandy outwash or aeolian deposits. They are nearly level through very steep soils on glaciofluvial landforms. Saturated hydraulic conductivity is high or very high. Detailed soil delineation of the entire site was not conducted however the soil types observed in the field appeared to match the NRCS mapping quite well. Wetland Soils As previously mentioned no wetland soils exist on the site. The nearest wetland area is approximately 70' west of the site. This wetland was flagged on April 28, 2011. The boundary was determined with the aid of a Dutch Hand Auger. Blue flagging numbered 1 to 10 was used to demarcate the boundary. It is shown on the existing conditions maps included with the application. The NRCS Web Soil Survey depicts the wetland soil to be a Walpole sandy loam. The Walpole Series consists of very deep,poorly drained sandy soils formed in outwash and stratified drift. They are nearly level to gently sloping soils in low- lying positions on terraces and plains. Saturated hydraulic conductivity is moderately rapid in the surface layer and subsoil, and rapid or very rapid in the substratum. The soil profiles observed on the site did not exactly match the typical profile for a Walpole soil. The surface horizons were observed to have a much thicker organic horizon at the surface than typically found and mottling was not very Megson&Heagle Civil Engineers&Land Surveyors,LLC E? Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT Page 6 prominent in the subsoil. This may be due to the likelihood of excessive erosion of the area up gradient of the wetland. This would coincide with the apparent eroded swales on the site. The proximity of the I-291 corridor has also likely altered the soil profile. Some professional judgment was needed to delineate the boundary. Soils, vegetation, evidence of surface water in the form of drift lines, and other topographic features were used to assist in the boundary determination. The overall quality of this wetland area is limited by it's proximity to the highway. This area is a remnant tip of a larger wetland system cut off to the south and on the other side of the highway corridor. Previous disturbance on the site has also reduced the overall quality. The area does retain some of its former functions and values primarily by providing limited wildlife habitat and nutrient retention and sediment trapping. Potential Impacts General No direct impacts or losses to wetland resources are proposed in connection with this project. In addition, no regulated activities are proposed. The only potential impacts to wetland resources would be secondary impacts resulting from the proposed activities up gradient to the resources. These potential impacts are evaluated as follows. Wetland Impacts Potential impacts to the adjacent wetland area were evaluated for stotmwater water runoff short term during construction and long term after construction. Other impacts considered were potential changes in hydrology from the stormwater management and groundwater control systems. Upon evaluation of the proposed site plans,the proposed activities appear to avoid any negative impacts to the adjacent wetland area. The erosion and sedimentation control plan follows the state guidelines and careful implementation will provide adequate protection of the wetland. Phasing of the plan is an important element of the plan. A majority of the site does not drain toward the adjacent wetland. The portion of the site that does is proposed to be in a separate phase and done during the dry season. This area is also protected by a permanent detention basin that can be utilized as a temporary sediment basin during construction. Wood chips produced on the site will be used for E&S as well. Megson&Heagle Civil Engineers&Land Surveyors,LLC 1 Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT Paee 7 The stormwater management system is designed to retain and filter out pollutants by utilizing a sediment fore bay, detention basin and linear vegetated swales. The i system also effectively maintains existing drainage patterns and spreads out the flow to different locations through level spreaders. These measures will prevent any negative impacts from sediments and pollutants on the wetland. In addition, no diversion of surface water is proposed that would alter the wetland hydrology. Another element of the site design considered involves control of groundwater in the area of the athletic fields. Under drains are proposed in the fields due to the seasonally high groundwater table in that area. However,due to the separating distance between the under drains and the wetland,the groundwater hydrology of the wetland will not be adversely affected. These under drains will only affect the ground water underneath the athletic fields. Groundwater collected in the under drains is proposed to drain through the storm drainage system and ultimately into the wetland. Vernal Pool Impacts Potential impacts to nearby vernal pools were evaluated for stormwater water runoff short term during construction and long term,post construction. These are located to the west of the site in relatively flat areas. The nearest potential vernal pool is located about 280' to the west of the proposed site. A map is included in the appendix showing the location. As previously mentioned, the site does not appear to direct surface water to any of the vernal pools west of the site. Observations were made during the site visits to determine if any apparent indications were present to conclude this. This included looking for any channels or other means for surface water to reach the pools. The field indications are the surface water from the site is retained in shallow surface depressions located at the toe of the slope then infiltrated into the ground. The surface water that drains to the pools does not come from the site. Due to this condition,none of the activities proposed for the site will affect any potential vernal pools to the west. Summary In summary,no wetlands,watercourses or vernal pools exist on the proposed school site. Wetlands and vernal pools do exist to the west of the site. The proposed activities will not adversely affect these offsite resources. In addition, no State Listed Species were found on or in close proximity to the site.

(RCSA See. 26-306) The pine barrens tiger beetle, also known as big sand, occupies blowouts and sand plains of dry—xeric, loose shifting sands, without water that are sparsely vegetated, such as pine barrens. Upon review of your application and the maps included with your application,the project appears to have no conflict with this species. However, if any work is to be conducted in tiger beetle habitat as described above, field surveys of the site should be performed by a qualified entomologist prior to the initiation of such work. A report summarizing the results of such surveys should include (1) the survey date(s); (2) descriptions of the habitat; (3) notes on the presence/absence of State-listed invertebrate species; (4) detailed maps of the area surveyed including the location and extent of State-listed invertebrate species; and (5) a statement/resume indicating the entomologist's qualifications. The report should be sent to Jenny Dickson Oenny.dickson@ct.gov)for further review. Natural Diversity Data Base information includes all information regarding critical biological resources available to us at the time of the request. This information is a compilation of data collected over the years by the Department of Energy & Environmental Protection's Natural History Survey and cooperating units of DEEP, private conservation groups and the scientific community. This information is not necessarily the result of comprehensive or site-specific field investigations. Consultations with the Data Base should not be substituted for on-site surveys required for environmental assessments. Current research projects and new contributors continue to identify additional populations of species and locations of habitats of concern, as well as, enhance existing data. Such new information is incorporated into the Data Base as it becomes available. Please be advised that this is a preliminary review and not a final determination. A more detailed review may be conducted as part of any subsequent environmental permit applications submitted to DEEP for the proposed site. Please be advised that the Wildlife Division has not made a field inspection of the proposed project nor have we seen detailed timetables for work to be done. Should state permits be required or should state involvement occur in some other fashion, specific restrictions or conditions relating to the species discussed above may apply, In this situaApA),gdAijpgLl;vA]htion of the proposal by the DEEP Wildlife 79 Elm Street, Hartford,CT 06106-5127 WWW.Ct.gov/deep Affirmative ActionlEqual Opportunity Employer - Soil Scientist,Environmental&Wetlands Report CREC International Magnet Elementary School South Windsor,CT Appendix D NRCS Soils Map Megson&Heagle Civil Engineers&Land Surveyors,LLC -- 403 740 463 000 403 800 4832020 4632980 463 040 4631100 403 160 463 220 T20 3w 531, 79'W 52" ..........

Date: September 13, 2011 CREC 111 Charter Oak Ave Hartford, CT 06106 CC. Fritz Morris—Perkins Eastman From: Jeffrey H. Folger—Environmental Planner,Town of South Windsor Re: Appl. #11-29P - Review of the proposed CREC Magnet School site plan -Plans dated 09/06/11. I have reviewed the proposed plan with the following initial comments: 1. The stormwater reports states that the proposed catchbasins on the site will be equipped with four- foot sumps to provide storage for road sand used in the winter. The detail on the plans shows a two-foot sump. Please change the detail on the plans to correspond with the engineers report. 2. Show the 80-foot upland review area associated with the flagged wetland on all sheets that show the wetland. 3. The proposed retention basin bottoms must be comprised of topsoil with a high organic content. An amendment of compost to bring the percentage of organics to 30%is required. This will provide a medium to facilitate vigorous plant growth, retail soil moisture, while also enhancing the basin's ability to adsorb metals present in runoff. 4. The E&S narrative states that the project will be accomplished in three phases. Tasks required in each phase are listed. Will each phase be cleared and grubbed separately? 5. Please show proposed locations of topsoil stockpiles on the plans. 6. The planting of the bottoms of the retention basins are proposed to be accomplished using a seed mix from Ernst seed farms,number 126. This mix contains a large percentage of grass species. I would recommend using seed mix number 131. This mix contains a greater diversity of emergent vegetation suitable for a wet environment. 7. The E&S narrative describes the use of diversion dikes and swales to protect the respective phases from on site runoff. The proposed locations of these structures must be shown on the plans. They can be altered in the field,but showing them on the plans will enable a prospective grading contractor to more accurately bid the job by knowing what is expected of them. 8. What are the anticipated velocities of stormwater flows exiting the proposed level spreaders? Cc. IWA/CC,Town Engineer, Dir.
