BOX 1167 21 JEFFREY DRIVE SOUTH WINDSOR, CT 06074 PHONE: 860.291.8755 FAX: 860.291.8757 www.designprofessionalsinc.com CIVIL & TRAFFIC ENGINEERS / PLANNERS / SURVEYORS / GIS ANALYSTS / LANDSCAPE ARCHITECTS Serving Connecticu t, Massachusetts, & Rhode Island Narrative Statement Site Plan/Special Exception Application New Pleasant Valley Elementary School 591 Ellington Road South Windsor, Connecticut DPI Proj. No. 4022.D March 16, 2021 The Town of South Windsor is proposing to build a new 102,150 square feet elementary school for approximately 806 students and 130 staff members at its roughly 25-acre campus easterly of Ellington Road and westerly of Long Hill Road. The “New Pleasant Valley Elementary School”, approved in a recent referendum, will be situated northerly of the existing Pleasant Valley Elementary School and is expected to open for the start of the Fall of 2023 school year. The existing school will remain open and operational during the construction of the new school, at which time the existing school will be razed to make room for future sports fields. The site design team consists of Drummey Rosane Anderson, Incorporated (DRA), architects; Design Professionals,Inc (DPI), civil engineers & land surveyors; SLR Consulting (SLR), landscape architects, environmental consultants, and traffic engineers; Consulting Engineering Services (CES), site lighting and MEP consultants; and Welti Geotechnical, P.C. (Welti), geotechnical engineers. The site plan includes a new 30 feet wide access drive, which will connect the school with Ellington Road and Long Hill Road. The Ellington Road entrance has a boulevard-style entrance and will align with the existing Parkview Drive. The access drive will have a companion concrete sidewalk, ranging from 6 to 8 feet wide. A circumferential loop on the western side of the new building will afford access to one of the three parking lots and the parent drop-off area. The other accessways will provide entry to the second and third parking lots as well as the primary bus drop- off area, terminating at a cul-de-sac for buses and emergency vehicles. The future multi-purpose and sports fields will be accessible by a fourth parking lot off Ellington Road, in the southwest corner of the site where the current school sits. A water quality basin for stormwater management will be located to the north of the access drive in the northwest corner of the site along with a wetland creation area. Various play areas are proposed both north and south of the school and adjacent to the multi-purpose sports field, with connectivity between the two areas by walkways. There is also an outdoor classroom proposed south of the school. The school will be served by all public utilities, including public water, sewer, telecommunications, electrical and natural gas. The new school site is a forested area. The landscape plan includes buffer plantings to compliment the remaining forested area around the site perimeter, and existing trees will remain to the east of the school as a buffer between the school’s Long Hill Road neighbors. Residential areas are to the west and east of the school. The school building is situated over 300 feet from Ellington Road and G:\jobs\4022\4022.D\Applications\PZC\PZC Submission 1 (2021-03-16)\4022.D PZC Narrative Statement.docx from Long Hill Road. The closest residence to the west (west side of Ellington Road) is well over 400 feet from the proposed school building, and the closest residence to the east (west side of Long Hill Road) is approximately 200 feet from the school building beyond the remaining forested buffer. As stated in the traffic report by SLR, traffic impacts are expected to be minimal. Indeed, the new site drive will serve to alleviate some existing traffic conditions on the school campus, by further distributing traffic rather than concentrating it. All parent drop-off and pick-up traffic will enter and leave the site via the Ellington Road entrance. All bus and staff traffic will utilize the Long Hill Road entrance. In speaking with the transportation coordinator, it was indicated that all bus traffic will enter and leave the site from and to the north towards Pleasant Valley Road. This portion of Long Hill Road was widened and improved in recent years. A total of 241 parking spaces are proposed for the new school, 181 in the immediate vicinity of the new school and approximately 60 spaces to remain near the existing school at the southwest corner of the site along Ellington Road. These 60 spaces can be increased to 75 spaces at the time the parking lot is moved and reconstructed to accommodate the future sports fields. Of the 181 parking spaces near the new school, 118 are contained east of the school for staff use. 40 are west of the school to be used for visitors and additional staff members. 23 spaces are located north of the school to be utilized for parent pick-up from the pre-kindergarten program. As a part of this application, a request is being made for a modification to the parking requirements from the 409 required per the Zoning Regulations to the 241 provided on the initial site plan, a reduction of 168 spaces. The design team has worked closely with the school administrators to ensure the 181 spaces provided in the vicinity of the school are sufficient to support the daily operations given the projected student and staff levels. This request is similar to the modification that was previously granted for the new Orchard Hill Elementary School. The applicant is requesting a Special Exception to allow for an educational institution in a residential zone. Per the South Windsor Zoning Regulations, the proposed land use is subject to the Special Exception Review Criteria outlined in Section 8.4 B of the Zoning Regulations. We believe the proposed elementary schools building and associated site improvements meet the review criteria, namely: 1. The proposal is consistent with the goals and objectives of the Plan of Conservation and Development. The POCD supports the redevelopment of town facilities “that improve the quality of life for South Windsor residents”, which aligns with the goals of this proposal. 2. The application has met the requirements of the zoning regulations. The application meets the requirements of the regulations for an educational facility in a residential zone. 3. The land is physically suited to the proposed use. The land is currently used as an elementary school and will continue to be suitable for the proposed development with the expansion of the existing property to include additional town-owned lots. This property is served by all public utilities. 4. Minimal, if any, adverse environmental impacts are created. This development will have minimal environmental impact as demonstrated by the submitted plans and reports. G:\jobs\4022\4022.D\Applications\PZC\PZC Submission 1 (2021-03-16)\4022.D PZC Narrative Statement.docx 5. No traffic or other hazards will be created. A detailed traffic report prepared by SLR has been submitted with the application indicating the proposed school with have little impact on the surrounding roadway network. 6. The impacts on the capacity of the present and proposed utilities, street, drainage systems, sidewalks, and other elements of the infrastructure will be minimal. The proposed building will utilize current public water, sewer, and natural gas facilities available along the property frontage in Ellington Road. Drainage systems will collect and treat stormwater runoff and discharge at or below peak volumes for the evaluated storm events. 7. There will be minimal or no adverse effects on existing uses in the area. Proper buffer plantings will be installed to screen the new school from surrounding residential and non- residential uses alike. Given the majority of the site’s existing use as an elementary school, the new building and site improvements will not have any adverse effects on other uses in the area. 8. Surrounding property values will be conserved. It is expected that existing property values will not be adversely impacted due to the enhancement of this public facility. 9. The character of the neighborhood will be maintained or minimally disrupted. The new school building will be minimally disruptive to the neighborhood by preservation of vegetation along residential uses and the inclusion of additional plantings in and around the proposed development. The building will compliment other public facilities in town and provide an enhanced sense of community. 10. The general welfare of the community will be served. The general welfare of the community will be served and improved through the redevelopment of the school with a modern educational facility that greatly improves capacity and accessibility. 11. There is a balance between neighborhood acceptance and community needs. This lot currently serves as an educational institution and the proposed development will allow for growth of the town’s resources and provide visual and environmental enhancements to the property. As stated earlier, the proposed school is approximately 200 feet from the nearest house with a dense buffer in between. Attention has been paid to the surrounding neighbors to protect their privacy and character of their homes on both Ellington Road and Long Hill Road. Therefore, the neighborhood acceptance is balanced with the community needs. 12. Historic factors are adequately protected; or due consideration to preservation of historic factors has been demonstrated. There are no known historic factors that will be impacted on the site as established during preliminary correspondence with the State Historic Preservation Office. 13. The overall physical appearance of the proposed development is compatible with surrounding development and the Commission’s goals for the neighborhood/corridor. The character of the existing school building will be improved with the architectural design and exterior finishes of the new building. The look of the new school will also be complimented by associated landscaping, lighting, and material selections throughout the site. G:\jobs\4022\4022.D\Applications\PZC\PZC Submission 1 (2021-03-16)\4022.D PZC Narrative Statement.docx 14. The architectural design is aesthetically pleasing and blends well into the surrounding area. The character of the existing school building will be improved with the proposed architectural design and finishes of the new building. As such, the design team has reviewed the 14 criteria for Special Exception approval in Section 8.4.B., and we believe this project meets all of the criteria, therefore warranting approval to provide necessary growth for the Town of South Windsor. We look forward to reviewing this application with Town Staff and the Commission and are available should you have any questions or comments.

The properties are referenced on the South Windsor Tax Assessors map as GIS No. 30300591, 30300623, & 30300647, respectively. The proposed development will include the construction of a 102,150+ sf elementary school and associated site improvements to include but not be limited to new access driveways, parking areas for vehicles, sidewalks, landscaping, lighting, utilities, common access drive, and stormwater management BMP’s. The total combined tract area is 24.91 acres. 19.149 acres of the parcel is proposed to be disturbed during construction. For more information, please refer to the plans entitled “Pleasant Valley Elementary School ~ Site Plan Modification / Special Exception ~ 591 Ellington Road ~ South Windsor, CT” prepared by Design Professionals, Inc., and dated March 16, 2021, as amended. Pre-Development Site Conditions The existing surficial characteristics of the area to be developed can be primarily classified as undisturbed woodland areas in the north region of the tract and developed school areas to the south. Review of the topography in the area indicated that stormwater runoff from the site would flow to one of three design points: • Design Point 1: Existing CB in Ellington Road, ultimately conveying flows to the Podunk River (EXCB-8) • Design Point 2: Sheet flow across the northern and eastern watershed boundaries • Design Point 3: Sheet Flow across the southern property boundary An existing ridge line spans from the north west corner of the tract to the south east corner of the tract, creating the major watershed divide for areas draining to DP1 and DP2. A small area to remain undisturbed drains to DP3. Existing conditions watershed delineations are identified in the Existing Conditions Drainage Map located in Appendix F. Based on Natural Resources Conservation Service (NRCS) Hydrologic Soil Group (HSG) mapping, soils types A, B, C are located on site. See Appendix C for The NRCS Soil Map & Data. An evaluation was performed to quantify the peak rate of stormwater discharge offsite to the design point. The Natural Resources Conservation Service’s TR-55 Manual was followed in predicting the peak rates of runoff and volumes. HydroCAD computer modeling software was utilized. Peak rates of stormwater runoff were evaluated for the 2-, 10-, 25-, 50- and 100-year storm events. For more information, please refer to the enclosed Pre-Development Drainage HydroCAD Report located in Appendix A. Page 3 Post-Development Site Conditions A conventional stormwater collection system consisting of catchbasins, manholes, and underground culverts is proposed to convey storm runoff to a proposed water quality basin. The basin was designed to attenuate peak discharges and provide treatment of stormwater onsite. The proposed basin will have a bottom elevation of 85.50 and a top elevation of 96.00 (Emergency spillway at 95.50). The basin will be constructed with an underdrain system to ensure complete drainage between storm events, and retention of the determined water quality volume for the site. The underdrain system will be a 6-inch perforated PVC for the conveyance of infiltrated runoff. The PVC will have an invert / flow line set one foot below the bottom of the pond at elevation 84.50. A 6- and 10-inch orifice will be installed in the outlet structure at elevations 88.6 and 89.0, respectively. The orifice size and locations have been designed to attenuate peak discharges for 2-, 10-, 25-, and 100-year storm events. The outlet structure will discharge to a 15-inch RCP. The outlet structure’s top of frame will be set at elevation 94.90 and will serve as an additional emergency stormwater flow release measure. The 100-year storm maximum water elevation is expected to reach 92.82+ so the outlet structure’s top of frame should never receive runoff under any of the evaluated storm conditions. See Appendix B for the Post Development Condition and Pond summary HydroCAD reports. The Proposed Conditions Drainage Map for the site can be found in Appendix F. Analysis of Results The pre-development and post-development conditions were analyzed using HydroCAD consistent with National Resource Conservation Service (NRCS) hydrology methods. The discharge location (Design Point #1) was identified as a point of interest for assessing downstream effects. The following table contains the data generated from the HydroCAD software: Reach 2 year 10 year 25 year 50 year 100 year DP#1 – Existing CB in Ellington Road (EXCB-8) Pre 1.79 11.37 19.97 26.94 35.32 Post 1.17 11.05 18.05 23.41 29.63 DP#2 – Sheet Flow across NE Watershed boundary Pre 0.03 0.59 1.32 1.98 2.90 Post 0.03 0.59 1.32 2.01 2.97 DP#3 – Sheet Flow across Southern Property Boundary Pre 0.00 0.00 0.00 0.01 0.03 Post 0.00 0.00 0.00 0.01 0.03 As seen in the table above, the subject project will result in peak runoff rates in the proposed condition that are less than the peak runoff rates of the existing condition for 2-, 10-, 25- and 100-year design storms for design points 1 & 3. Peak discharges at the design point 3 will match existing conditions following 2-, 10-, and 25-year storm events. Analysis results did however indicate that there will be a slight increase in the peak rate of discharge during 50- and 100-year Page 4 storm events. It is our opinion that the observed increases at this location will have negligible impact to downgradient offsite areas. Storm Sewer Collection System The proposed subsurface stormwater collection and conveyance system was designed to adequately convey proposed runoff under 10- year storm event conditions. The design of the storm sewers followed the guidelines set forth in the Connecticut Department of Transportation’s Drainage Manual. It is estimated that during a 10-year storm event, all proposed subsurface culverts will convey storm runoff without resulting in any unacceptable flooding conditions. The computations are included as Appendix D. Water Quality The proposed Forebay and Water Quality Depression (PP1), were sized in accordance with the 2004 Connecticut Stormwater Quality Manual, to provide 10% and 100% of the determined water quality volume, respectively. See Appendix E for calculations. The proposed temporary sediment basin was sized in accordance with the 2002 Connecticut Guidelines for Soil Erosion and Sediment Control. Conclusion The proposed stormwater management system as discussed herein and shown on the referenced plans is appropriate for the proposed development on the subject site, is consistent with Town and State requirements, and should not pose any detrimental impacts to the environment.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor Custom Soil Resource Report 8 components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

Custom Soil Resource Report 21 Soil Information for All Uses Soil Properties and Qualities The Soil Properties and Qualities section includes various soil properties and qualities displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 22 Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Figure 1 displays the site location map. The new Pleasant Valley School will be constructed on land owned by the Town, which consists of the existing school parcel along with four recently acquired parcels to the north of the existing site. All three new parcels front Ellington Road (Route 30) and one parcel also fronts Long Hill Road to the east. The existing school will remain in place and operational until the new buildings are constructed. At that time, the existing school will be demolished. The new Pleasant Valley School will include part‐time prekindergarten and full‐time elementary school (kindergarten through 5th grade). The proposed site plan is shown in Figure 2. As shown in Figure 2, site access for the new school is proposed at the intersection of Ellington Road (Route 30) at Parkview Drive and off Long Hill Road near the St. Francis of Assisi Church parking lot. The work comprising the study consisted of several tasks including field reconnaissance, data collection, review of roadway and traffic conditions, estimation of site‐development‐generated traffic volumes, and assessment of future traffic operations. For this study, the following intersections were evaluated: 1. Ellington Road (Route 30) at Pleasant Valley Road 2. Ellington Road (Route 30) at Chapel Road 3. Ellington Road (Route 30) at Parkview Drive and the proposed driveway 4. Long Hill Road at the proposed driveway Figure 3 depicts the study area. March 15, 2021 Mr. Jim Barrett Page 2 SLR International Corporation slrconsulting.com EXISTING CONDITIONS The existing information involving the vehicle volumes, vehicle speeds, and accident history was collected to determine the existing conditions of the area around the elementary school. Site Environs and Existing Traffic Ellington Road (Route 30) is classified as a two‐way urban principal arterial roadway that runs northeast/southwest with one lane in each direction. The posted speed limit is 40 miles per hour (mph). Sidewalks are not present within vicinity of the new school site. The existing Pleasant Valley School takes access via Ellington Road (Route 30) and as mentioned previously, the new school is proposed to have access via the intersection of Ellington Road (Route 30) and Parkview Drive. Long Hill Road is classified as a two‐way urban local roadway that runs north/south with one lane in each direction. The posted speed limit is 35 mph. Sidewalks are not present within vicinity of the new school site. As mentioned previously, the new school is proposed to have secondary access via Long Hill Road near the St. Francis of Assisi Church parking lot. Pleasant Valley Road is classified as a two‐way urban minor arterial roadway that runs east/west with one lane in each direction. The posted speed limit is 30 mph. A sidewalk is present on the south side of the roadway from Ellington Road (Route 30) to Long Hill Road. Chapel Road is classified as a two‐way urban collector roadway that runs east/west with one lane in each direction. The posted speed limit is 35 mph. Sidewalks are present on the north side of the roadway. Crash Data Summary Information on traffic accident statistics for Ellington Road (Route 30) and Long Hill Road were obtained from the Connecticut Crash Data Repository for the approximately 3‐year period of January 1, 2017, to October 9, 2020. The accident data collected for this period is shown in Table 1, summarized by location. A total of 32 crashes were reported on Ellington Road (Route 30) between Pleasant Valley Road and Chapel Road and a total of 7 crashes were reported on Long Hill Road between Pleasant Valley Road and Chapel Road during the 3‐year period. More than 50% of the crashes resulted in property damage only. One suspected serious injury was reported, and no fatalities were reported. On Ellington Road (Route 30), the most common collision type was angle collisions, comprising 44% of reported crashes, followed by rear‐ end collisions at 34%, and then hit‐fixed‐object collisions at 13%. The most crashes occurred at the intersection of Ellington Road (Route 30) and Pleasant Valley Road. One bicycle collision occurred on Ellington Road (Route 30) between Parkview Drive and Chapel Road. On Long Hill Road, the most common collision type was hit‐fixed‐object collisions, comprising 57% of reported crashes. Two of the reported collisions on Long Hill Road involved hitting a tree and two involved hitting a pole or other support. It is March 15, 2021 Mr. Jim Barrett Page 3 SLR International Corporation slrconsulting.com important to note that one of the collisions reported on Ellington Road (Route 30) occurred during the COVID‐19 pandemic (after the stay‐at‐home order issued for Connecticut on March 23, 2020).

March 15, 2021 Mr. Jim Barrett Page 4 SLR International Corporation slrconsulting.com Existing Traffic Volumes Traffic monitoring data from March 2019 for Ellington Road (Route 30) northeast of Chapel Road was obtained from the Connecticut Department of Transportation (CTDOT). The annualized average daily traffic (AADT) at this location was 6,600 vehicles. To supplement the State traffic monitoring data, SLR International Corporation (SLR) conducted Average Daily Traffic (ADT) counts on Ellington Road (Route 30) in front of the existing Pleasant Valley School on Thursday, August 20, 2020, and on Long Hill Road in front of the St. Francis of Assisi Church parking lot on Tuesday, August 25, 2020. The ADT on Ellington Road (Route 30) was 6,167 vehicles and the ADT on Long Hill Road was 793 vehicles. It is important to note that these ADT counts were conducted during Phase 2 of Connecticut's Reopen Plan due to the COVID‐19 pandemic and when South Windsor Public Schools were not open. The ADT count data is included in the Appendix. Due to the COVID‐19 pandemic and its overall effect on reducing current travel and traffic patterns, new intersection turning movement traffic counts would not be indicative of normal traffic operations, as shown in the ADT counts. Intersection peak‐hour volumes were assembled from the Traffic Study for the Proposed Education Playcare at 742 Ellington Road (Route 30) prepared by DLS Traffic Engineering dated February 5, 2019, and from the Traffic Assessment for 360 Ellington Road (Route 30) prepared by Langan dated June 3, 2019. The volume data is included in the Appendix. Existing Traffic Speeds As stated previously, SLR conducted Automatic Traffic Recorder (ATR) counts on Ellington Road (Route 30) and Long Hill Road. The 85th percentile speed on Ellington Road (Route 30) was found to be 48.5 mph, which is 8.5 miles over the posted speed limit. Thea 85th percentile speed on Long Hill Road was found to be 42.1 mph, which is 7.1 miles over the posted speed limit. The speed data is included in the Appendix. PROPOSED DEVELOPMENT As stated previously, the new Pleasant Valley School will replace the existing Pleasant Valley Elementary School. The new school will include part‐time prekindergarten and full‐time elementary grades (kindergarten through 5th grade). Access for the new school is proposed at the intersection of Ellington Road (Route 30) at Parkview Drive and off Long Hill Road near the St. Francis of Assisi Church parking lot. Proposed Development Trip Generation The proposed site‐generated peak‐hour trips were estimated based on the existing Pleasant Valley Elementary School operations (based on conversations with school staff) and projected enrollment and staff numbers. Table 2 summarizes the site‐generated traffic estimates for the existing Pleasant Valley Elementary School and the proposed new Pleasant Valley School during the study peak hours. March 15, 2021 Mr. Jim Barrett Page 5 SLR International Corporation slrconsulting.com As shown in Table 2, the existing Pleasant Valley Elementary School has approximately 600 students and 87 staff members. It is estimated that the existing school generates 258 vehicle trips (151 vehicles entering and 107 exiting) during the morning peak hour and 194 vehicle trips (75 vehicles entering and 119 exiting) during the afternoon peak hour. The new Pleasant Valley School is anticipated to have approximately 693 elementary students, 110 pre‐kindergarten students, and 120 staff members. The new school is estimated to generate 490 new vehicle trips (275 vehicles entering and 215 vehicles exiting) during the morning peak hour and 420 total new vehicle trips (180 vehicles entering and 240 vehicles exiting) during the afternoon peak hour. The estimated trip generation is within the range for what an elementary school is estimated to generate using statistical data published by the Institute of Transportation Engineers (ITE)1 and was approved by CTDOT Bureau of Policy and Planning.

Figure 4 illustrates the distribution for the site‐generated traffic through the study area. It is important to note that it is assumed that all buses and staff will use the Long Hill Road access, while all student pick‐up/drop‐off vehicles will use the Ellington Road access. 1 Trip Generation, 10th Edition, Institute of Transportation Engineers, 2017 March 15, 2021 Mr. Jim Barrett Page 6 SLR International Corporation slrconsulting.com Based on the existing Pleasant Valley Elementary School trip generation and trip distribution, the existing Pleasant Valley Elementary School trips were assigned to the study area intersections. Figure 5 displays the resulting existing Pleasant Valley Elementary School trip assignment. Based on the new Pleasant Valley School trip generation and trip distribution, the new Pleasant Valley School trips were assigned to the study area intersections. Figure 6 displays the resulting new Pleasant Valley School trip assignment. FUTURE (2023) CONDITIONS The new Pleasant Valley School is anticipated to be built and occupied by fall 2023. Future (2023) conditions were evaluated both with and without the new school to determine possible traffic impacts. Background Traffic Volumes The background traffic scenario is reflective of future (2023) conditions if the new school was not built. Background (2023) Conditions include traffic associated with other nearby expected upcoming developments as well as general traffic growth. Based on correspondence with the Town of South Windsor and CTDOT, at the intersection of Ellington Road (Route 30) and Pleasant Valley, the 2021 Combined Volumes from the Proposed Education Playcare Traffic Study were used as the baseline peak‐hour volumes. At the intersection of Ellington Road (Route 30) and Chapel Road, the 2020 Build Volumes from the 360 Ellington Road Traffic Study were used as the baseline peak‐hour volumes. At the intersection of Ellington Road (Route 30) and Parkview Drive, through volumes were balanced from the two other study intersections and the volumes in and out of Parkview Drive were estimated using the ITE Trip Generation Manual. On Long Hill Road, morning and afternoon peak‐hour volumes were extracted from the ADT counts conducted in August 2020 and factored up by 25% (to account for the reduction of traffic patterns due to the COVID‐19 pandemic) to develop the baseline peak‐hour through volumes at the proposed driveway location. Based on the methodology used in the Proposed Education Playcare Traffic Study and the 360 Ellington Road Traffic Study, the 2021 and 2020 baseline traffic volumes were projected to future (2023) conditions using an annual growth rate of 1% per year. Background (2023) Conditions peak‐hour traffic volumes were estimated by applying the annual growth rate and adding the Parkview Drive trip assignment (shown in Figure 7) to the baseline peak‐hour volumes. The resultant Background (2023) Conditions peak‐hour traffic volumes are shown in Figure 7. The Background (2023) Conditions peak‐hour traffic volumes were approved by CTDOT Bureau of Policy and Planning. Combined Traffic Volumes The combined traffic scenario is reflective of future (2023) conditions once the new Pleasant Valley School is built and occupied. Combined (2023) Conditions peak‐hour traffic volumes were estimated by subtracting the existing Pleasant Valley Elementary School trips (shown in Figure 5) from the Background March 15, 2021 Mr. Jim Barrett Page 7 SLR International Corporation slrconsulting.com (2023) Conditions traffic volumes (shown in Figure 7) and adding the new Pleasant Valley School trips (shown in Figure 6). The resultant Combined (2023) Conditions peak‐hour traffic volumes are shown in Figure 8. The Combined (2023) Conditions peak‐hour traffic volumes were approved by CTDOT Bureau of Policy and Planning. It is important to note, as part of the school project it is recommended to widen Ellington Road (Route 30) southwest of Parkview Drive and restripe Ellington Road (Route 30) to install northbound and southbound left‐turn lanes at the intersection of Ellington Road (Route 30) at Parkview Drive and the proposed driveway. The addition of the left‐turn lanes is included under Combined (2023) Conditions. INTERSECTION ANALYSIS Intersection capacity analysis and queue analysis were performed at the study intersections under Background (2023) and Combined (2023) Conditions to evaluate each intersection's ability to process traffic volumes. These evaluations were used to determine possible traffic impacts from the new elementary school, based on the comparison of background and combined traffic operations. Intersection Capacity Analysis Intersection operation results are expressed as a level of service (LOS). LOS is used to provide a qualitative evaluation of the efficiency of operations of an intersection in terms of delay and inconvenience based on certain quantitative calculations. A description of the various LOS designations, A through F, is given in the Appendix. LOS A describes operations with very low average control delay per vehicle while LOS F describes operations with long average delays. The study intersections were evaluated using Synchro 10 (Trafficware) traffic analysis software package. Table 3 summarizes the capacity analysis findings under Background (2023) and Combined (2023) Conditions. The Synchro analysis worksheets are included in the Appendix. It is important to note LOS A to LOS D are generally considered acceptable conditions. However, in some areas, LOS E during peak hours is often deemed acceptable for short periods of time and can indicate an efficient tradeoff between traffic flow and the amount of land devoted to the movement of motor vehicles. As shown in Table 3, all movements at the study intersections are expected to operate at acceptable LOS (LOS A to LOS E) under Background and Combined Conditions during both peak periods. Furthermore, at the two signalized intersections, the new school is not expected to change the overall LOS.

Intersection Site Distance Analysis Intersection sight distances were measured at the intersection of Ellington Road (Route 30) at the proposed driveway and Long Hill Road at the proposed driveway. Intersection sight distance is determined through the creation of clear sight triangles. Each quadrant of the intersection should contain a triangular area free of obstructions. For vehicles approaching an intersection, the length of the legs of the triangle should be long enough such that the driver can see any potentially conflicting vehicles in sufficient time to slow or stop before colliding. For vehicles departing from an intersection, the length of the legs of the triangle should be sufficient for a stopped driver to depart from the intersection and turn onto the main road safely. Intersection sight distances were measured in accordance with criteria set forth in the 2003 CTDOT Highway Design Manual. The 85th percentile speed was measured on Long Hill Road north of the proposed driveway location. The Long Hill Road count determined the 85th percentile speed to be 38.9 mph northbound and 42.3 mph southbound. The posted speed limit is 35 mph. There is adequate sight distance based on CTDOT minimum requirements at the proposed driveway for both the posted and 85th percentile speeds on Long Hill Road. March 15, 2021 Mr. Jim Barrett Page 11 SLR International Corporation slrconsulting.com On Ellington Road (Route 30), the proposed driveway is located on a hill. The apex of the hill is located approximately 100 feet northeast of the proposed driveway. The 85th percentile speed on Ellington Road (Route 30) was measured southwest of the proposed driveway on the downhill section of the road. The Ellington Road (Route 30) speed counter provided a good estimate of the speed of the traffic approaching from the southwest, which was 48.1 mph. The posted speed limit is 40 mph. For a design speed of 50 mph, approximately 555 feet of sight distance is required for a passenger car turning right onto Ellington Road (Route 30). The sight distance for vehicles approaching from the southwest exceeds the CTDOT guideline for both the posted and 85th percentile speeds. Because of the location of the speed counter, an estimate for the speed of the traffic approaching from the northeast could not be ascertained. There is a signalized intersection approximately 800 feet to the northeast of the proposed driveway. In addition to traveling uphill, the vehicles approaching the proposed driveway from the northeast are likely approaching from a stop in many cases. As a result, the 85th percentile speed of the traffic approaching from the northeast is very likely closer to the posted speed limit. The posted speed limit on Ellington Road (Route 30) is 40 mph. For a design speed of 40 mph, 445 feet of sight distance is required for a passenger car turning left onto Ellington Road (Route 30). The available sight distance is just slightly over the guideline for the posted speed limit. It is important to note that vegetation within the clear sight triangles must be kept trimmed, especially during the spring and summer, to ensure that sufficient intersection sight distance is provided throughout the year. School Zone While the sightlines are adequate for the posted speed limit on both driveways and the 85th percentile speed for three of the four sightlines, it is important to understand that some of the most vulnerable road users, children, exist in school areas. Higher vehicular speeds directly correlate with increased rates of pedestrian fatalities. With a vehicle speed of 40 mph there is approximately an 80% chance of fatality, if the vehicle speed is reduced to 25 mph, the chance of fatality reduces to approximately 20%.2 Consequently, to improve the roadway safety near the Pleasant Valley School, it is recommended to designate the portion of Ellington Road (Route 30) and Long Hill Road near the new Pleasant Valley School driveways as school zones, to reduce vehicle speeds during arrival and dismissal times. Under Connecticut General Statue, the Office of the State Traffic Administration (OSTA) can designate any part of a road next to or close to school property as a school zone. By designating a portion of Ellington Road (Route 30) and Long Hill Road as a school zones, the speed limit would be reduced to 25 mph during school pick‐up and drop‐off times. The school zones can be defined with the installation of traffic control devices, including signs and pavement markings. Well‐placed traffic control devices can provide the critical information to drivers and students to alert and educate. The Manual on Uniform Traffic Control Devices (MUTCD) includes uniform 2 National Highway Traffic Safety Administration March 15, 2021 Mr. Jim Barrett Page 12 SLR International Corporation slrconsulting.com standards for school zone signage and markings. Figure 9 displays the proposed school zone traffic control devices on Ellington Road (Route 30) and Figure 10 displays the same for Long Hill Road. SUMMARY This study was conducted to assess the transportation implications of the proposed new Pleasant Valley School development that will replace the existing Pleasant Valley Elementary School in South Windsor, Connecticut. To determine a profile of existing conditions, detailed field reconnaissance and data assembly efforts were undertaken. Estimates of traffic that will be generated by the proposed development were developed based on the existing Pleasant Valley Elementary School operations and projected enrollment. Intersection capacity and queue analyses were performed at the study intersections. Intersection sight distance analysis was also performed at the two proposed driveways. With the construction of the new Pleasant Valley School, all study intersections are expected to operate at adequate LOS during both peak periods. Furthermore, at the two signalized intersections, the new school is not expected to change the overall LOS. Additionally, all approach lanes are expected to provide adequate storage length under Combined (2023) Conditions during both peak periods. At the two proposed driveways, the 95th percentile queues are not expected to exceed approximately nine vehicles. Lastly, there is adequate sight distance at both driveway locations based on CTDOT minimum requirements and the posted speed limits on Ellington Road and Long Hill Road. However, to enhance school safety, we recommend that school zones be established on both Ellington Road and Long Hill Road. We hope this report is useful to you.
