The project includes work on Tax Map 60, Block 33, Lot 7 located in the Town of South Windsor. The property is 1.38 acres with 0.26 acres of wetlands located at the southeastern side of the property. The wetlands were flagged by Ian Cole, LLC. The proposed project is seeking a Wetland permit from the Inland Wetland Commission; as well as a Site Plan and Special Exception permit from the Planning and Zoning Commission. The proposed facility is to be 5,132 square feet with a large fenced in outdoor play area for the dog-daycare. The building is to be located near the central point of the property with the parking lot to the east and fenced in play area to the west. The proposed parking lot will be constructed for 12 parking spaces, including 2 ADA-accessible space near the front entrance. A dumpster is to be located at the rear of the parking lot and is to be a fenced in encloser to provide a screening from the street. The parking lot is to drain to the south into a stone trench and sediment forebay before being routed to an infiltration basin. The basin will also receive runoff from the play area as well as the roof leaders of the building will be routed into the basin. The building will have utilities services from the public utilities located within Nutmeg Road South. Floor drains are proposed within the building and will be discharged into a 1,000-gallon oil/water separator. Approval and permitting will be coordinated with the South Windsor WPCA and the CT DEEP. The project will be built out in 2 phases. Phase 1 will consist of the front section of the building, parking lot and stormwater features. The outdoor play area will also be fenced in and will be expanded to encompass the rear building section. Phase 2 will be the construction of the rear building section.

The Developer/Contractor shall also be responsible for installing and maintaining all erosion control facilities shown herein. 3.All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition by ripping or disking along land contours until mulch, vegetation, or other permanent erosion control BMPs are installed. No soils in areas outside project street rights-of-way and future pavement shall remain exposed by land disturbing activity for more than thirty (30) days before required temporary or permanent erosion control (e.g. watering, seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the Town Engineer. 4.All inlets shall be cleaned prior to occupancy. 5.All slopes greater than 3:1 shall be protected with Erosion Control Blankets (S150 by North American Green or approved equal) or Hydroseeded with Tackifier 6.All erosion control measures shall remain intact and operational until the site has been stabilized and vegetation is thoroughly established. This may occur after completion of construction, therefore it is critical for the Developer, Contractor and\or Owner to understand the erosion control responsibilities and maintain the erosion control measures. 7.To minimize erosion of the sandy soils, vegetation shall be established immediately following completion of grading within each area. Vegetation may consist of temporary seeding or final loam and seed. 8.If areas of work are not addressed by this plan or sediment and erosion issues arise in areas not covered by this plan, then the plan shall be augmented in the field. Contractor shall be responsible to insure no sediment or erosion problems encroach upon abutting property. This may require additional barriers, swales and bales. 9.All erosion and sediment control measures shall conform to the 2024 Connecticut Guidelines for Soil Erosion and Sediment Control manual.

B.EROSION CONTROL NOTES 1.The purpose of this plan is to depict the required onsite temporary construction erosion control measures. 2.All measures in the plan shall meet as a minimum the best management practices set forth in 2024 Connecticut Guidelines for Soil Erosion & Sediment Control. 3.Whenever practical, natural vegetation shall be retained, protected or supplemented. The stripping of vegetation shall be done in a manner that minimizes soil erosion. 4.Appropriate erosion and sediment control measures shall be installed prior to land disturbance. 5.The area of disturbance shall be kept to a minimum. Disturbed areas remaining idle for more than 30 days shall be stabilized. 6.Measures shall be taken to control erosion within the project area. Sediment in runoff water shall be trapped and retained within the project area using approved measures. 7.All temporary erosion and sediment control measures shall be maintained in functioning condition until final site stabilization is accomplished. 8.All temporary erosion and sediment control measures shall be removed after final site stabilization. Trapped sediment and other disturbed soil areas resulting from the removal of temporary measures shall be permanently stabilized within 30 days unless conditions dictate otherwise. 9.The Town of South Windsor shall reserve the right to require further erosion control practices during construction should they find it necessary. 10.The responsible party shall install, inspect, report, operate, and maintain all stormwater management and erosion control measures required by these plans. 11.Temporary erosion control measures shall be installed in strict accordance with project plans. In addition, similar measures shall be installed where and when the field condition, or field operation of the individual site contractor, may warrant. 12.All disturbed areas designated to be turf, shall receive a minimum application of 4 inches of loam (compacted thickness), prior to final seeding and mulching. 13.In the event that, during construction of any portion of this project, a winter shutdown is necessary, the contractor shall stabilize all incomplete work and provide for suitable methods of diverting runoff in order to eliminate sheet flow across frozen surfaces. 14.Dust shall be controlled by the use of water as necessary throughout the construction period, in accordance with 2024 Connecticut Guidelines for Soil Erosion & Sediment Control. 15.In no way are those temporary erosion control measures indicated on these plans to be considered all inclusive. The contractor shall use judgement in installing supplementary erosion control measures where and when specific site conditions and/or construction methodologies may warrant. 16.Graded areas shall be vegetated to insure erosion control by seeding, mulching, and fertilizing. Disturbed areas shall be planted with suitable plant materials. 17.Grading shall not exceed a ration of 3 horizontal to 1 vertical without special erosion control measures. netting or similar material shall be provided on slopes with a ration greater than 3:1 while ground cover is being established. C.RESPONSIBILITY 1.The responsibility for implementing and maintaining the Soil Erosion and Sedimentation Control Plan rests with the OWNER OF RECORD where any development of the parcel gives cause to erosion and sedimentation. It is also to be said that the OWNER OF RECORD shall be held responsible for informing all concerned regarding responsibility of the SE&SC plan and seeing that the plan becomes a part of the deed in the event the title of the property is transferred. The costs of all drainage erosion and sedimentation control measures will therefore rest with the OWNER OF RECORD. 2.Contact Person: David Turkington Contact Phone: (860) 841-3779 222.2 225.37 200 200 PROP.

Project Description The applicant is seeking to develop the vacant parcel into a Dog Daycare and Grooming facility. The property will be developed with a single driveway curb cut, parking spaces, and outdoor fenced in area for the dog daycare. B. Existing Site Conditions The parcel has been vacant since the construction of Nutmeg Road South. The land surrounding the property has developed and been zoned Industrial I. The property is located on the eastern side of Nutmeg Road South, at the eastern portion of the ‘S’ turn in the roadway. C. Proposed Site Conditions The proposed development will have a commercial building constructed for the use of a dog daycare and grooming facility. The building will be located at the center of the site with parking to the east of the building and a fenced in outdoor yard for the dog daycare on the west side. The development with have a single driveway at the northside of the property with parking spaces on either side of the driveway. The building will be served by public water from Nutmeg Road South and public sanitary sewer runs within the property along Nutmeg Road South. Storm drainage analysis & design A. Methodology The primary method of predicting the surface water runoff rates utilized in this report is a computer program entitled Hydraflow Hydrographs Extension for Autodesk Civil 3D. The Hydraflow program forecasts the rate of surface water runoff based upon several factors, including information on land use, vegetation, watershed areas, soil types, time of concentration, rainfall data, storage volumes and hydraulic capacities of structures. The program predicts the amount of runoff as a function of time. The NOAA National Weather Service was used to determine the rainoff from the specific project location. This website supply information of the rainfall on an intensity (in/hr) and depth (inch) for the known precipitation. Rainfall events with recurrence frequencies of 2, 10, 25, and 100-yr Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report October 23, 2024 ~ 2 ~ during a 24-hr duration were used a data in the Hydraflow analysis. This information can be found in Appendix B. Soil types in the watershed were determined from the Natural Resources Conservation Service of Web Soil Survey, prepared by the United States Department of Agriculture, Soil Conservation Service. The soils over the property are show as Udorthents-Urban Land, and typically has a moderate rate of exfiltration. The soils map can be found in Appendix A. The time of concentration was calculated for the analysis using the TR-55 method. Deep test pits were performed on the property within at the northeast and southern corner of the property. Along with the deep test pits, permeability test was completed to determine the exfiltration rate from the detention systems. For the permeability rates, a safety factor of 50% was taken into consideration for the exfiltration rate. The soil test results can be found in the Infiltration Feasibility Report found in Appendix E. B. Pre-Development Drainage Conditions In order to evaluate the impact of the proposed development, one (1) Point of Analysis (POA) was analyzed to demonstrate that the peak rates of runoff would not increase from the site improvements. The primary POA, Design Point A, is located at the southern boundary line of the project area as the existing property slopes north to south and west to east, away from Nutmeg Road South. The site flows towards the wetlands and watercourse along the southern property boundary with slopes ranging from 2.0% to 10%. Flows from the site flow towards the wetlands along the eastern property boundary as well as the swale along the southern property boundary. The wetlands and swale are interconnected and the swale discharges to the north through a culvert under the abutting property’s driveway. The existing conditions model was used to determine existing flow conditions. The existing conditions flow can be found in Appendix C. C. Post-Development Drainage Conditions The same POA from the Pre-Development scenario was used in the Post-Development analysis. Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report October 23, 2024 ~ 3 ~ The overall drainage patterns remain the same as minimal areas from the site flow into Nutmeg Road South and the remaining areas continue the flow to the east and south. Runoff from the development area’s impervious is captured within the infiltration basin with the pavement area directed to a sediment forebay. The grass areas and roof drainage will be directed directly into the basin. D. Stormwater Water Quality Treatment The stormwater management plan is designed have the pavement area drain into a sediment forebay for pretreatment and then flow into the infiltration basin. The proposed roof and grass areas will either overland flow and be collected and directed into the infiltration basin via pipe networks. The WQV is the initial flush of stormwater that contains most of the sediment and pollutants as defined in the CT DEP 2024 Stormwater Quality Manual. The WQV will be retained by a sediment forebay prior to entering the infiltration basin. The primary treatment of the stormwater runoff for water quality is infiltration through the infiltration basin bottom. CT DEEP requires treatment practices to store and/or infiltrate the the Water Quality Volume through incorporated Best Management Practices. The WQV is based upon the impervious area and the required depth of runoff, depending on location and proximity to a wetland or other critical area. The Water Quality Volume calculations are included in Appendix F. Overall, the stormwater management plan has been designed in accordance with concepts and recommendations found in the CT 2024 Stormwater Quality Manual. E. Stormwater Conveyance System The project site is designed with a Low Impact Design and allows the parking lot and majority of the grass area to be diverted overland sheet flow into swales or a stone infiltration system. The only conveyance system would be for the roof leaders to be collected and discharged directly into the infiltration basin. The roof leader system has been analyzed using the Rational Method to Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report October 23, 2024 ~ 4 ~ convey the 100‐year design storm. The pipe sizing calculations are included in Appendix G of this report. F. Summary The goal of the stormwater management system is two-fold, to ensure peak rates of runoff do not have a negative impact on down gradient properties or storm drainage systems and to maintain water quality by promoting infiltration and renovation of the stormwater on site by utilizing concepts and recommendations from the CT DEEP 2024 Stormwater Quality Manual. Peak rates of runoff flow and volume from this site have been mitigated by installing a stormwater systems to detain and treat the proposed stormwater runoff from the site. The subject site complies with the Town of South Windsor’s Stormwater Management and Erosion Control Regulations and CT DEEP 2024 Stormwater Quality Manual in regards to stormwater treatment and runoff reduction. Proposed stormwater best management practices (BMP) are designed in accordance with the 2024 CT Stormwater Quality Chapter 13 – Structure Stormwater BMP Design Guidance. In addition, stormwater discharges, in terms of peak rate of runoff and total volume, are consistent with the Town of Farmington and 2024 CT Stormwater Quality Manual Standard 1. The results are reported below in Table 1 and 2.

Temporary Erosion Control Measures Temporary erosion and sediment control measures are indicated on the design plans, construction details, general notes and within the drainage report. Although not integral to this stormwater report, due to the size of the proposed development both temporary and permanent erosion control measures will also be specified within the project’s Stormwater Pollution Prevention Plan (SWPPP). All erosion control measures specified are designed to reduce or eliminate potential soil migration and water quality degradation, both during and after the construction period. The following temporary erosion control measures will be implemented; • Silt Fence and/or Silt Logs • Catch Basin Filters – Silt Sock or Dandy Bags • Erosion Control Blankets on slopes 3:1 and steeper • Riprap Aprons & Spillway Stabilization • Turf Establishment - Hydroseeding with mulch and tackifiers These temporary erosion control measures are also discussed in the project’s Operation and Maintenance plan contained in the appendices of this report. In addition to the above-listed erosion control measures, references are made throughout the project documents to the 2024 Connecticut Guidelines for Soil Erosion and Sediment Control for additional measures, as necessary. B. Construction Sequence A site-specific construction sequence sensitive to limiting soil loss due to erosion and associated water quality degradation was prepared specifically for this project and is shown on the project plans. As pointed out in the erosion control notes, it is important for the contractor to recognize that proper judgment in the implementation of work will be essential if erosion is to be limited and protection of completed work is to be realized. Moreover, any specific changes in sequence and/or field conditions affecting the ability of specific erosion control measures to adequately serve their intended purpose should be reported to this office by the contractor. Furthermore, Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report October 23, 2024 ~ 7 ~ the contractor is encouraged to supplement specified erosion control measures during the construction period where and when in his/ her best judgment, additional protection is warranted.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Hydrologic Soil Group—State of Connecticut, Western Part (260 Nutmeg Road South) Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 9/17/2024 Page 2 of 4 Hydrologic Soil Group Map unit symbol Map unit name Rating Acres in AOI Percent of AOI 306 Udorthents-Urban land complex B 2.8 35.7% 308 Udorthents, smoothed B 5.0 64.3% Totals for Area of Interest 7.7 100.0% Description 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. 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.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Proposed Peak flows at Design Point A are a summation of the detention pond release (P2) and drainage basin P1 2. Per 2024 CT Stormwater Quality Manual Standard 2 - Peak Runoff Attenuation during the 2-yr, 24-hr post-development peak flow rate is to be 50% of the 2-yr, 24-hr pre-development peak flow. Due to the small drainage area, all the proposed development is captured and the surrounding area is unable to be contained and decrease the peak flow even further. The infiltration basin is self-containing during the 2-yr storm. A waiver is being requested.

The system is identified on the plans as Infiltration Basin #1 1. Location of Infiltration practices Filtration is proposed in the following areas: • The infiltration basin, Infiltration Basin #1, is proposed in the southern portion of the property. 2. Existing Topography Existing topography in the proximity of Infiltration Basin #1 is approximately 2-3% slope. 3. Test Pit Location Three test pits were dug on the property, with one being in the vicinity of the Infiltration Basin. One field permeability test was completed in the vicinity of the Infiltration Basin. See grading and drainage plans as well as details. Proposed Dog Daycare and Grooming 260 Nutmeg Road South, South Windsor, Connecticut Infiltration Feasbility Report September 27, 2024 4. Season High Water Table Elevation Infiltration Basin #1: Bottom of Filtration Section Elevation = 67.33 High Contour Elevation (Existing) = 69.6 Groundwater Elevation = 64.93 Bedrock = None Found Bottom of Test Pit = 64.02 Separation to Bottom of Test Pit = 2.40’ 5. Infiltration Rate Study Infiltration rates for the Infiltration Basin were calculated by from field testing using a double ring infiltrometer. Testing was done in conformance with the 2024 Stormwater Quality Manual, Chapter 10, subsection Soil Evaluation Guidance. From the deep test pits, it was noticed the soil had a Sandy characteristics. The test came back with a 10.58 in/hr. Using a safety factor of 2 from the slower of the field tests, the infiltration rate utilized in the drainage analysis is as follows: • Infiltration Basin #1 = 5.288 in/hr 6.

Compliance with Stormwater Facility Maintenance Requirements The owner of the subject property is responsible for ensuring that stormwater facilities installed on the property are properly maintained and that they function as designed. In some cases, this maintenance responsibility may be assigned to others through special agreements. Any transfer of responsibility for inspection and maintenance activities or transfer of ownership shall be documented in writing. The contract documents will require the contractor to designate a person responsible for maintenance of the sedimentation control features during construction. Long- term operation and maintenance for the stormwater management facilities are presented below. II. Inspection & Maintenance – Annual Reporting Requirements for the inspection and maintenance of stormwater facilities, as well as reporting requirements, are included in this Stormwater Management Operation and Maintenance (O&M) Manual. Verification that the Stormwater facilities have been properly inspected and maintained; copies of the annual report should be documented on site for future reporting upon request. Copies of the Inspection and Maintenance forms for each of the stormwater facilities are located in Appendix B and C. A standard annual reporting form is provided in Appendix A. III. Preventative Measures to Reduce Maintenance Costs The most effective way to maintain your water quality facility is to prevent the pollutants from entering the facility in the first place. Common pollutants include sediment, trash & debris, chemicals, dog wastes, runoff from stored materials, illicit discharges into the storm drainage system and many others. A thoughtful maintenance program will include measures to address these potential contaminants and will save money and time in the long run. Key points to consider in your maintenance program include: • Educate property owners/residents to be aware of how their actions affect water quality, and how they can help reduce maintenance costs • Keep properties, streets and gutters, and parking lots free of trash, debris, and lawn clippings • Ensure the proper disposal of hazardous wastes and chemicals • Plan lawn care to minimize the use of chemicals and pesticides • Sweep paved surfaces and put the sweepings back on the lawn • Be aware of automobiles leaking fluids. Use absorbents such as cat litter to soak up drippings – dispose of properly O&M Manual ~ 2 ~ • Re-vegetate disturbed and bare areas to maintain vegetative stabilization. • Clean out the upstream components of the storm drainage system, including inlets, storm sewers, and outfalls • Do not store materials outdoors (including landscaping materials) unless properly protected from runoff IV. Access All stormwater management facilities located on the site have a designated access location. Refer to the Site Plan – Grading & Drainage Plan for access locations. V. Safety Keep safety considerations at the forefront of inspection procedures at all times. Likely hazards should be anticipated and avoided. Never enter confined space (outlet structure, manhole, etc) without proper training or equipment. A confined space should never be entered without at least one additional person present. If a toxic or flammable substance is discovered, leave the immediate area and contact the local authority at 911. Potentially dangerous (e.g., fuel, chemicals, hazardous materials) substances found in the areas must be referred to the local authority immediately for response. The emergency contact number is 911. Vertical drops may be encountered in areas located within and around the facility. Avoid walking on top of retaining walls or other structures that have a significant vertical drop. If a vertical drop is identified within the pond that is greater than 48” in height, make the appropriate note/comment on the maintenance inspection form. If any hazard is found within the facility area that poses an immediate threat to public safety, contact the local authority immediately. VI. Field Inspection Equipment It is imperative that the appropriate equipment is taken to the field with the inspector(s). This is to ensure the safety of the inspector and allow the inspections to be performed as efficiently as possible. Below is a list of the equipment that may be necessary to perform the inspections of all Stormwater Management Facilities: • Protective clothing and boots • Safety equipment (vest, hard hat, confined space entry equipment • Communication equipment O&M Manual ~ 3 ~ • Operation and Maintenance Manual for the site including stormwater management facility location maps • Clipboard • Stormwater Facility Maintenance Inspection Forms (See Appendix B) • Manhole Lid Remover • Shovel Some of the items identified above need not be carried by the inspector (manhole lid remover, shovel, and confined space entry equipment). However, this equipment should be available in the vehicle driven to the site. VII. Inspecting Stormwater Management Facilities The quality of stormwater relies heavily on the proper operation and maintenance of permanent best management practices. Stormwater management facilities must be periodically inspected to ensure that they function as designed. The inspection will determine the appropriate maintenance that is required for the facility. A. Inspection Procedures All stormwater management facilities are required to be inspected by a qualified individual. Inspections should follow the inspection guidance found in Appendix B of this manual. B. Inspection Report The person(s) conducting the inspection activities shall complete the appropriate inspection report for the specific facility. Inspection reports are located in Appendix B. VIII. Maintenance Requirements Stormwater management facilities must be properly maintained to ensure that they operate correctly and provide the water quality treatment for which they were designed. Routine maintenance performed on a frequently scheduled basis can help avoid more costly rehabilitative maintenance that results when facilities are not adequately maintained. The Long-Term Inspection and Maintenance Log provides a record of maintenance activities. Maintenance Logs for each facility type are provided in Appendix C. Catch Basins • Catch basins may require frequent maintenance. Depending on the location, this may require several cleanings of the sumps each year. At a minimum, it is recommended that catch basins be inspected at least twice annually, once following snowmelt and once following leafdrop. And cleaned as indicated by inspection. • Sediment should be removed when it approaches half the sump depth. O&M Manual ~ 4 ~ • If floating hydrocarbons are observed during an inspection, the material should be removed immediately by skimming, absorbent materials, or other method, and disposed in conformance with applicable state and federal regulations. • Cleaning may require vacuum-truck instead of “clam shell” to avoid damage to hood. • Damaged hoods should be replaced when noted by inspection. IX. Control of Invasive Species During maintenance activities, check for the presence of invasive plants and remove in a safe manner as described on the following pages. They should be controlled as described in Appendix D. Invasive plants are introduced, alien, or non-native plants, which have been moved by people from their native habitat to a new area. Some exotic plants are imported for human use such as landscaping, erosion control, or food crops. They also can arrive as "hitchhikers" among shipments of other plants, seeds, packing materials, or fresh produce. Some exotic plants become invasive and cause harm by: • becoming weedy and overgrown; • killing established shade trees; • obstructing pipes and drainage systems; • forming dense beds in water; • lowering water levels in lakes, streams, and wetlands; • destroying natural communities; • promoting erosion on stream banks and hillsides; and • resisting control except by hazardous chemicals.

The project includes work on Tax Map 60, Block 33, Lot 7 located in the Town of South Windsor. The property is 1.38 acres with 0.26 acres of wetlands located at the southeastern side of the property. The wetlands were flagged by Ian Cole, LLC. The proposed project is seeking a Wetland permit from the Inland Wetland Commission; as well as a Site Plan and Special Exception permit from the Planning and Zoning Commission. The proposed facility is to be 5,132 square feet with a large fenced in outdoor play area for the dog-daycare. The building is to be located near the central point of the property with the parking lot to the east and fenced in play area to the west. The proposed parking lot will be constructed for 12 parking spaces, including 1 ADA-accessible space near the front entrance. A dumpster is to be located at the rear of the parking lot and is to be a fenced in encloser to provide a screening from the street. The parking lot is to drain to the south into a stone trench and sediment forebay before being routed to an infiltration basin. The basin will also receive runoff from the play area as well as the roof leaders of the building will be routed into the basin. The building will have utilities services from the public utilities located within Nutmeg Road South. Floor drains are proposed within the building and will be discharged into a 1,000-gallon oil/water separator. Approval and permitting will be coordinated with the South Windsor WPCA and the CT DEEP. The project will be built out in 2 phases. Phase 1 will consist of the front section of the building, parking lot and stormwater features. The outdoor play area will also be fenced in and will be expanded to encompass the rear building section. Phase 2 will be the construction of the rear building section.

Russo, PLA, Assistant Planner Date: 11/19/24 Re: Appl #24-44P, 260 Nutmeg Road South LLC Dog Daycare & Grooming Planning Review Comments The following are the Planning Department comments. Building Department comments are attached. Engineering comments will be sent separately. Please make the necessary revisions and submit three COMPLETE sets of full-size revised plans and 10 sets of 11”x17” plans by 12/4/24 to be sent out with the agenda (tentatively scheduled for 12/10/24). Narrative Comments a. Special Exception review criteria, found in Section 8.4(B) of our Zoning Regulations, should be addressed in the narrative. There is particular concern related to the proposed traffic impact, as well as the environmental impact to water, soils, wildlife, and people from dog waste. Additionally, the applicant should address how muddy conditions in the outdoor play area will be mitigated to prevent increased sediment deposition in the infiltration basin. b. The narrative should address the days and hours of operation, the number of employees, and the number of dogs anticipated. There appears to be conflict between the use in the narrative and the use on Drawing C1. Is there an overnight boarding component proposed and how many dogs can be accommodated? c. The construction phasing must be more detailed and should be shown on the plans. A critical aspect of phasing is whether the individual phases can function on their own if one phase is never completed. More information regarding how the front and rear sections of the buildings work should be submitted, ideally in the form of architectural floor plans. Site Plan Comments 2. Drawing S1 (survey) a. The survey must bear the stamp and signature of a licensed professional surveyor. 3. Drawing C1 (layout & landscaping plan) a. The actual lot depth should be provided in the Zoning Information Table on Drawing C1. b. The zoning notes on Drawing C1 must be updated to show that the variance granted by ZBA for application #2680-06 was to allow for a 10’ rear yard setback. Thus, the rear yard setback in the Zoning Information Table must be changed to 10’ required and 57.8’ provided. c. The side yard setback in the Zoning Information Table must be changed to 86.8’. d. The grantee of the sewer easement in the Existing Easements Table must be updated to Town of South Windsor. South Windsor Planning Department Appl #24-44P, 260 Nutmeg Road South LLC Dog Daycare & Grooming Special Exception 1540 Sullivan Avenue, South Windsor, CT 06074 phone 860-644-2511, ext. 2229 e-mail justin.russo@southwindsor-ct.gov e. Parking requirements are calculated based on Table 6.4.3B of our Zoning Regulations. To accurately calculate the required parking for this use, the applicant should use the formula for both Industrial and Manufacturing, and Business Offices <50,000 sq ft of GFA. f. The Landscaping Information Table on Drawing C1 shows that 8 street trees are provided, but that is not indicated anywhere on the plan. Please show the locations of the street trees on the plan and clearly indicate the species and size. Due to close proximity to sensitive natural areas, the applicant must propose trees native to the northeastern US. Suggested species include: Quercus alba, Gleditsia triacanthos var. inermis, Acer rubrum. g. The Landscaping Information Table on Drawing C1 shows that 180 square feet of landscaping will be provided in the parking area, but species, size and quantities are not specified. Due to close proximity to sensitive natural areas, the applicant must propose perennials and groundcovers native to the northeastern US, and clearly indicate the sizes and quantity to be planted. Some suggested species include: Arctostaphylos uva-ursi, Phlox subulata, Echinacea purpurea, Rudbeckia fulgida. h. The Plant List on Drawing C1 shows three tree species but only two to be planted. Furthermore, the plan does not specify where each species will be planted. Please provide clarification. i. Will there be any foundation plantings around the building? The applicant should consider a mix of shrubs, perennials, and groundcovers native to the northeastern US that will provide aesthetic quality and environmental benefits to the site. Some suggested shrub species include: Viburnum dentatum ‘Blue Muffin’, Aronia arbutifolia, Ilex glabra ‘Densa’. j. There is an existing Sycamore tree within the Town right-of-way beyond the northwest corner of the property line. Efforts must be made to preserve this tree and protect it from construction damage and soil compaction. 4. Drawing C2 (grading & drainage plan) a. It appears that the proposed 70 and 71 contours are crossing in several areas around the proposed infiltration basin. Please revise the proposed contours to tie into existing grade. b. The proposed 72 and 70 contours at the midpoint of the channel between the sediment forebay and the infiltration basin are too close, showing a very steep slope. Please revise. c. Top of curb and bottom of curb spot elevations should be distinguished so staff can understand curb heights and accurately calculate proposed slopes. 5. Drawing C3 (utility plan) a. The linear foot label of the sanitary pipe runs should be updated to be accurate. Namely the 11 LF, 7 LF, and 21 LF 6” lines. 6. Drawing L1 (photometric plan) a. Provide cut sheets showing the proposed light fixture. Per Section 6.3.3(C) of our Zoning Regulations, lights must be top downward, full cutoff, or fully shielded or recessed. b. Due to close proximity to sensitive natural areas, the applicant must modify the distribution of A5 to eliminate or substantially reduce light spill into the woodland and wetland. c. Please consider changing the color temperature of the light from 4000K to 3000K. A warmer color temperature has less impact on our native flora and fauna and helps to maintain a darker sky.

Drawing ES1 (soil erosion & sediment control plan) a. Please clearly indicate the individual tree symbols that will be removed. b. The symbol for erosion control blanket/hydroseeding with tackifier should be shown on all 3:1 slopes or greater. c. The Project Information under the Soil Erosion and Sediment Control Narrative identifies this lot as being 4.15 acres. Please revise to show the actual size of 1.38 acres. d. The estimated construction schedule should be clarified to show the approximate start and finishing times of phase 1 and 2. e. Notes on this drawing frequently reference the incidental removal of invasive plant species. It is important to properly dispose of invasive plants and a separate note on the drawing should reflect this. Any invasive plants removed prior to flowering should be left out to dry and then disposed after death. Any invasive plants removed during and after flowering should be bagged and disposed off site through means of lawful incineration. 8. Drawing ES2 (erosion control notes and details) a. The loam & seed detail must be updated to reference the 2024 Connecticut Guidelines for Soil Erosion & Sediment Control. 9. Drawing D1 (construction details) a. Staking/guying of newly planted trees is generally discouraged and should be limited to areas exposed to high winds (such as coastal regions). The tree planting detail should be revised to eliminate staking/guying. b. It is a better practice to remove at least 2/3 of the burlap on a newly planted tree or shrub, if not to remove it completely. Both tree and shrub planting details should be revised to reflect this. 10. Drawing DB1 a. Please provide the manufacturer of the seed mixes shown in the Seed Mix & Fabric Legend. If you have any questions, please do not hesitate to contact me. Respectfully, Justin F. Russo, PLA, Assistant Planner MEMORANDUM To: Michele Lipe, Director of Planning From: Jeff Doolittle, P.E., Town Engineer Date: November 25, 2024 Re: App 24-44P – Proposed Dog Daycare and Grooming – 260 Nutmeg Road I have reviewed the above Plans and have the following comments: 1. There is an existing Type “C” catch basin in middle of the proposed driveway entrance. The catch basin appears to be located at a low point in the roadway, and it has two inlet pipes and one outlet pipe. The piping along the roadway changes direction at this catch basin. The catch basin cannot be relocated. Also, changing the existing catch basin to a Type “C-L” is not acceptable because it would be exposed to unnecessarily high volumes of traffic traveling over the top, which would result in severe levels of drainage structure deterioration. Shift the driveway so it is not over this catch basin. 2. Revise Site Plan Note No. 8 on Sheet C1 to “Wetlands are present per the Town of South Windsor.” Note that the Town of South Windsor does not have an official wetland map, so remove any reference to such a map. 3. Call out an ADA sidewalk ramp on Sheet C1 and include a detail for the ramp in the Construction Details. 4. Call out curbing for parking lot in plans. Is the curbing along the sidewalk integral with the sidewalk? Include a detail showing curbing along sidewalk. 5. Call out the cross hatched area along front edge of parking lot (facing the roadway) or include the cross hatching in the Legend. 6. Revise all references of CTDOT FORM 818 dated 2020 to CTDOT FORM 819 dated 2024. 7. Call out CTDOT HMA S0.375 for both the wearing course and the binder course in the Standard Duty Asphalt Paving Detail on Sheet D1. 8. Call out 6 inches of CTDOT Processed Aggregate Base for the base course shown in the Standard Duty Asphalt Pavement Detail. 9. Call out 5½ inches of CTDOT Subbase for the subbase course shown in the Standard Duty Asphalt Pavement Detail. 10. Call out CTDOT Class PCC04460 concrete in the Concrete Sidewalk detail on Sheet D1. Remove reference to the compressive strength and percent air entrainment shown in the detail, as these properties are included in CTDOT FORM 819. 11. Call out service wye connection to sanitary sewer main from building’s sanitary service on the Utility Plan (Sheet C3), as shown on the Sanitary Service Detail on Sheet D2. 12. Call out the type of proposed surface for the fenced in yard on Sheet C1, as well as other surfaces within the proposed lot clearing limits. 13. Clearly show the sewer easement. Eight (8) trees located every 40 feet are shown in the Landscaping Information table on Sheet C1. There shall not be any large trees within the sewer easement. 14. Sheet ES1 provides project information that refers to phases of development, where Phase 1 is for the front building and parking lot construction and phase 2 is for the rear building. Clearly call these phases out on Sheet C1. 15. Show all proposed grading on Sheet C1, particularly north of the fenced in area because the sheet flow arrows don’t match up with existing contour lines. 16. Provide larger outlet pipe from proposed infiltration basin, as a 4-inch HDPE will likely clog up. A 10 or 12-inch pipe might be more suitable. Call this out on Sheet C2. 17. Show elevation of emergency overflow spillway within the proposed infiltration basin on Sheet C2. Please let me know if there are any questions.

The project includes work on Tax Map 60, Block 33, Lot 7 located in the Town of South Windsor. The property is 1.38 acres with 0.26 acres of wetlands located at the southeastern side of the property. The wetlands were flagged by Ian Cole, LLC. The proposed project is seeking a Wetland permit from the Inland Wetland Commission; as well as a Site Plan and Special Exception permit from the Planning and Zoning Commission. Julie’s Barks and Bubbles will be relocating from their current location on Ellington Road to this development. The hours of operation will match the existing business with Monday to Friday, 7:00am to 5:00pm. The company is run and operated by the owner with no other employees. Throughout the day, there anticipates to be on average 15-20 dogs in the daycare program and 8-10 dogs for the grooming services. The traffic generated from the operation is minimal, anticipated 25-30 trips entering and exiting the site throughout the morning and similar trips through the afternoon. For the daycare program, the dogs are dropped off and picked up at a later date. For the grooming services, it is a mixture of drop off and pick up later on in the day; or the customers have the option to self-wash their dogs at the facility. For the building, there will be an open floorplan and a mixture between grooming and daycare services. Floor drains are proposed to allow maintenance of the floors to be easier. The floor drains will be connected to an oil/water separator to allow any dog hair/fur and other materials to be captured before discharge into the public sewers. The proposed facility is to be 5,132 square feet with a large fenced in outdoor play area for the dog-daycare. The building is to be located near the central point of the property with the parking lot to the east and fenced in play area to the west. The proposed parking lot will be constructed for 12 parking spaces, including 1 ADA-accessible space near the front entrance. A dumpster is to be located at the rear of the parking lot and is to be a fenced in enclosure to provide a screening from the street. For the outdoor dog area will be a fenced in yard will be a black-coated vinyl fence with either privacy slates or fabric wind screen. The surface area is to be pea stone gravel / wood mulch. This material is the same material used at their current location and has minimal issues with muddy conditions. There is no anticipation for an increase of sediment washing from the play area into the swale and infiltration basin. Any dog waste/fecal matter that occurs will be picked up either immediately or as soon as the dogs reenter the facility. The employee does a walkthrough of the area to ensure all waste is picked up and disposed of properly. The parking lot is to drain to the south into a stone trench and sediment forebay before being routed to an infiltration basin. The basin will also receive runoff from the play area as well as the roof leaders of the building will be routed into the basin. Through the development of the proposed project, the wetlands will be protected and undisturbed. The area of development is designed to be collected and directed to an infiltration basin. The basin is designed to collect the runoff and infiltrate into the ground during lower storm events. The bottom of basin is designed to be 2-ft above Lambert Civil Design, LLC 34 Misty Lane Monroe, CT 06468 the seasonal high-water table. The basin is also designed to provide a 100% TSS removal, 98% Phosphorus removal, and 100% Nitrogen removal. The building will have utilities services from the public utilities located within Nutmeg Road South. Floor drains are proposed within the building and will be discharged into a 1,000-gallon oil/water separator. Approval and permitting will be coordinated with the South Windsor WPCA and the CT DEEP. The project will be built out in 2 phases. Phase 1 will consist of the front section of the building, parking lot and stormwater features. The outdoor play area will also be fenced in and will be expanded to encompass the rear building section. Phase 2 will be the construction of the rear building section. A Phase 1 Site Plan has been added to the Site Plan set for visual aid on what will be completed during Phase 1. Overall, the location is best suited for this project. The site development plans meet all the zoning requirements. The proposed facility is over 900 feet from the closest residential structure and should have no disturbance to the industrial/commercial uses along Nutmeg Road South. The building, parking area and fenced-in dog yard are centrally located on the property to the best of our ability and have limited disturbance to the abutting properties. The building will have a similar industrial look to the exterior of the building to match the surrounding properties. The fencing will also have a privacy aspect incorporated into it so as to not cause any disturbance between the dogs and vehicles/pedestrians. There are anticipated to be minimal environmental impacts as the proposed development does not encroach into the wetlands and has the proposed development drain into a stormwater detention system for treatment and infiltration per the 2024 CT Stormwater Quality Manual. The dog waste will be picked up in a timely fashion to minimize any potential for waste entering the infiltration basin and wetlands. The company also requires a license from the Connecticut Department of Agriculture and must meet their safety and health requirements. From this use, the added traffic on Nutmeg Road South will be minimal to negligible. The use of the project also entails no additional tractor-trailers driving on the roadway and idling on the property so noise levels from the vehicles will be minimal.

The Developer/Contractor shall also be responsible for installing and maintaining all erosion control facilities shown herein. 3.All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition by ripping or disking along land contours until mulch, vegetation, or other permanent erosion control BMPs are installed. No soils in areas outside project street rights-of-way and future pavement shall remain exposed by land disturbing activity for more than thirty (30) days before required temporary or permanent erosion control (e.g. watering, seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the Town Engineer. 4.All inlets shall be cleaned prior to occupancy. 5.All slopes greater than 3:1 shall be protected with Erosion Control Blankets (S150 by North American Green or approved equal) or Hydroseeded with Tackifier 6.All erosion control measures shall remain intact and operational until the site has been stabilized and vegetation is thoroughly established. This may occur after completion of construction, therefore it is critical for the Developer, Contractor and\or Owner to understand the erosion control responsibilities and maintain the erosion control measures. 7.To minimize erosion of the sandy soils, vegetation shall be established immediately following completion of grading within each area. Vegetation may consist of temporary seeding or final loam and seed. 8.If areas of work are not addressed by this plan or sediment and erosion issues arise in areas not covered by this plan, then the plan shall be augmented in the field. Contractor shall be responsible to insure no sediment or erosion problems encroach upon abutting property. This may require additional barriers, swales and bales. 9.All erosion and sediment control measures shall conform to the 2024 Connecticut Guidelines for Soil Erosion and Sediment Control manual.

B.EROSION CONTROL NOTES 1.The purpose of this plan is to depict the required onsite temporary construction erosion control measures. 2.All measures in the plan shall meet as a minimum the best management practices set forth in 2024 Connecticut Guidelines for Soil Erosion & Sediment Control. 3.Whenever practical, natural vegetation shall be retained, protected or supplemented. The stripping of vegetation shall be done in a manner that minimizes soil erosion. 4.Appropriate erosion and sediment control measures shall be installed prior to land disturbance. 5.The area of disturbance shall be kept to a minimum. Disturbed areas remaining idle for more than 30 days shall be stabilized. 6.Measures shall be taken to control erosion within the project area. Sediment in runoff water shall be trapped and retained within the project area using approved measures. 7.All temporary erosion and sediment control measures shall be maintained in functioning condition until final site stabilization is accomplished. 8.All temporary erosion and sediment control measures shall be removed after final site stabilization. Trapped sediment and other disturbed soil areas resulting from the removal of temporary measures shall be permanently stabilized within 30 days unless conditions dictate otherwise. 9.The Town of South Windsor shall reserve the right to require further erosion control practices during construction should they find it necessary. 10.The responsible party shall install, inspect, report, operate, and maintain all stormwater management and erosion control measures required by these plans. 11.Temporary erosion control measures shall be installed in strict accordance with project plans. In addition, similar measures shall be installed where and when the field condition, or field operation of the individual site contractor, may warrant. 12.All disturbed areas designated to be turf, shall receive a minimum application of 4 inches of loam (compacted thickness), prior to final seeding and mulching. 13.In the event that, during construction of any portion of this project, a winter shutdown is necessary, the contractor shall stabilize all incomplete work and provide for suitable methods of diverting runoff in order to eliminate sheet flow across frozen surfaces. 14.Dust shall be controlled by the use of water as necessary throughout the construction period, in accordance with 2024 Connecticut Guidelines for Soil Erosion & Sediment Control. 15.In no way are those temporary erosion control measures indicated on these plans to be considered all inclusive. The contractor shall use judgement in installing supplementary erosion control measures where and when specific site conditions and/or construction methodologies may warrant. 16.Graded areas shall be vegetated to insure erosion control by seeding, mulching, and fertilizing. Disturbed areas shall be planted with suitable plant materials. 17.Grading shall not exceed a ration of 3 horizontal to 1 vertical without special erosion control measures. netting or similar material shall be provided on slopes with a ration greater than 3:1 while ground cover is being established. C.RESPONSIBILITY 1.The responsibility for implementing and maintaining the Soil Erosion and Sedimentation Control Plan rests with the OWNER OF RECORD where any development of the parcel gives cause to erosion and sedimentation. It is also to be said that the OWNER OF RECORD shall be held responsible for informing all concerned regarding responsibility of the SE&SC plan and seeing that the plan becomes a part of the deed in the event the title of the property is transferred. The costs of all drainage erosion and sedimentation control measures will therefore rest with the OWNER OF RECORD. 2.Contact Person: David Turkington Contact Phone: (860) 841-3779 222.2 225.37 200 200 PROP.

Project Description The applicant is seeking to develop the vacant parcel into a Dog Daycare and Grooming facility. The property will be developed with a single driveway curb cut, parking spaces, and outdoor fenced in area for the dog daycare. B. Existing Site Conditions The parcel has been vacant since the construction of Nutmeg Road South. The land surrounding the property has developed and been zoned Industrial I. The property is located on the eastern side of Nutmeg Road South, at the eastern portion of the ‘S’ turn in the roadway. C. Proposed Site Conditions The proposed development will have a commercial building constructed for the use of a dog daycare and grooming facility. The building will be located at the center of the site with parking to the east of the building and a fenced in outdoor yard for the dog daycare on the west side. The development with have a single driveway at the northside of the property with parking spaces on either side of the driveway. The building will be served by public water from Nutmeg Road South and public sanitary sewer runs within the property along Nutmeg Road South. Storm drainage analysis & design A. Methodology The primary method of predicting the surface water runoff rates utilized in this report is a computer program entitled Hydraflow Hydrographs Extension for Autodesk Civil 3D. The Hydraflow program forecasts the rate of surface water runoff based upon several factors, including information on land use, vegetation, watershed areas, soil types, time of concentration, rainfall data, storage volumes and hydraulic capacities of structures. The program predicts the amount of runoff as a function of time. The NOAA National Weather Service was used to determine the rainoff from the specific project location. This website supply information of the rainfall on an intensity (in/hr) and depth (inch) for the known precipitation. Rainfall events with recurrence frequencies of 2, 10, 25, and 100-yr Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report December 2, 2024 ~ 2 ~ during a 24-hr duration were used a data in the Hydraflow analysis. This information can be found in Appendix B. Soil types in the watershed were determined from the Natural Resources Conservation Service of Web Soil Survey, prepared by the United States Department of Agriculture, Soil Conservation Service. The soils over the property are show as Udorthents-Urban Land, and typically has a moderate rate of exfiltration. The soils map can be found in Appendix A. The time of concentration was calculated for the analysis using the TR-55 method. Deep test pits were performed on the property within at the northeast and southern corner of the property. Along with the deep test pits, permeability test was completed to determine the exfiltration rate from the detention systems. For the permeability rates, a safety factor of 50% was taken into consideration for the exfiltration rate. The soil test results can be found in the Infiltration Feasibility Report found in Appendix E. B. Pre-Development Drainage Conditions In order to evaluate the impact of the proposed development, one (1) Point of Analysis (POA) was analyzed to demonstrate that the peak rates of runoff would not increase from the site improvements. The primary POA, Design Point A, is located at the southern boundary line of the project area as the existing property slopes north to south and west to east, away from Nutmeg Road South. The site flows towards the wetlands and watercourse along the southern property boundary with slopes ranging from 2.0% to 10%. Flows from the site flow towards the wetlands along the eastern property boundary as well as the swale along the southern property boundary. The wetlands and swale are interconnected and the swale discharges to the north through a culvert under the abutting property’s driveway. The existing conditions model was used to determine existing flow conditions. The existing conditions flow can be found in Appendix C. C. Post-Development Drainage Conditions The same POA from the Pre-Development scenario was used in the Post-Development analysis. Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report December 2, 2024 ~ 3 ~ The overall drainage patterns remain the same as minimal areas from the site flow into Nutmeg Road South and the remaining areas continue the flow to the east and south. Runoff from the development area’s impervious is captured within the infiltration basin with the pavement area directed to a sediment forebay. The grass areas and roof drainage will be directed directly into the basin. D. Stormwater Water Quality Treatment The stormwater management plan is designed have the pavement area drain into a sediment forebay for pretreatment and then flow into the infiltration basin. The proposed roof and grass areas will either overland flow and be collected and directed into the infiltration basin via pipe networks. The WQV is the initial flush of stormwater that contains most of the sediment and pollutants as defined in the CT DEP 2024 Stormwater Quality Manual. The WQV will be retained by a sediment forebay prior to entering the infiltration basin. The primary treatment of the stormwater runoff for water quality is infiltration through the infiltration basin bottom. CT DEEP requires treatment practices to store and/or infiltrate the the Water Quality Volume through incorporated Best Management Practices. The WQV is based upon the impervious area and the required depth of runoff, depending on location and proximity to a wetland or other critical area. The Water Quality Volume calculations are included in Appendix F. Overall, the stormwater management plan has been designed in accordance with concepts and recommendations found in the CT 2024 Stormwater Quality Manual. E. Stormwater Conveyance System The project site is designed with a Low Impact Design and allows the parking lot and majority of the grass area to be diverted overland sheet flow into swales or a stone infiltration system. The only conveyance system would be for the roof leaders to be collected and discharged directly into the infiltration basin. The roof leader system has been analyzed using the Rational Method to Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report December 2, 2024 ~ 4 ~ convey the 100‐year design storm. The pipe sizing calculations are included in Appendix G of this report. F. Summary The goal of the stormwater management system is two-fold, to ensure peak rates of runoff do not have a negative impact on down gradient properties or storm drainage systems and to maintain water quality by promoting infiltration and renovation of the stormwater on site by utilizing concepts and recommendations from the CT DEEP 2024 Stormwater Quality Manual. Peak rates of runoff flow and volume from this site have been mitigated by installing a stormwater systems to detain and treat the proposed stormwater runoff from the site. The subject site complies with the Town of South Windsor’s Stormwater Management and Erosion Control Regulations and CT DEEP 2024 Stormwater Quality Manual in regards to stormwater treatment and runoff reduction. Proposed stormwater best management practices (BMP) are designed in accordance with the 2024 CT Stormwater Quality Chapter 13 – Structure Stormwater BMP Design Guidance. In addition, stormwater discharges, in terms of peak rate of runoff and total volume, are consistent with the Town of Farmington and 2024 CT Stormwater Quality Manual Standard 1. The results are reported below in Table 1 and 2.

Temporary Erosion Control Measures Temporary erosion and sediment control measures are indicated on the design plans, construction details, general notes and within the drainage report. Although not integral to this stormwater report, due to the size of the proposed development both temporary and permanent erosion control measures will also be specified within the project’s Stormwater Pollution Prevention Plan (SWPPP). All erosion control measures specified are designed to reduce or eliminate potential soil migration and water quality degradation, both during and after the construction period. The following temporary erosion control measures will be implemented; • Silt Fence and/or Silt Logs • Catch Basin Filters – Silt Sock or Dandy Bags • Erosion Control Blankets on slopes 3:1 and steeper • Riprap Aprons & Spillway Stabilization • Turf Establishment - Hydroseeding with mulch and tackifiers These temporary erosion control measures are also discussed in the project’s Operation and Maintenance plan contained in the appendices of this report. In addition to the above-listed erosion control measures, references are made throughout the project documents to the 2024 Connecticut Guidelines for Soil Erosion and Sediment Control for additional measures, as necessary. B. Construction Sequence A site-specific construction sequence sensitive to limiting soil loss due to erosion and associated water quality degradation was prepared specifically for this project and is shown on the project plans. As pointed out in the erosion control notes, it is important for the contractor to recognize that proper judgment in the implementation of work will be essential if erosion is to be limited and protection of completed work is to be realized. Moreover, any specific changes in sequence and/or field conditions affecting the ability of specific erosion control measures to adequately serve their intended purpose should be reported to this office by the contractor. Furthermore, Proposed Dog Daycare and Groom 260 Nutmeg Road South, South Windsor, Connecticut Stormwater Management Report December 2, 2024 ~ 7 ~ the contractor is encouraged to supplement specified erosion control measures during the construction period where and when in his/ her best judgment, additional protection is warranted. C. Permanent Erosion Control Measures Similar to temporary erosion control measures, all permanent erosion control measures are indicated on the design plans, construction details, general notes, drainage report, SWPPP and O & M project documents. The following permanent erosion control measures will be implemented; • Bituminous Paved Roadway and parking lots • Closed drainage system (catch basins & piping) • Erosion Control Blankets • Inlet & Outlet Protection - Riprap Stabilization • Stormwater Basins with multi-stage outlets • Spillway Stabilization • Turf Establishment - Hydroseeding with mulch and tackifiers Each of the above-mentioned permanent erosion control measures are designed in a project- specific manner within both state and local regulatory compliance standards.

Hydrologic Soil Group—State of Connecticut, Western Part (260 Nutmeg Road South) Natural Resources Conservation Service Web Soil Survey National Cooperative Soil Survey 9/17/2024 Page 2 of 4 Hydrologic Soil Group Map unit symbol Map unit name Rating Acres in AOI Percent of AOI 306 Udorthents-Urban land complex B 2.8 35.7% 308 Udorthents, smoothed B 5.0 64.3% Totals for Area of Interest 7.7 100.0% Description 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. 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.

The system is identified on the plans as Infiltration Basin #1 1. Location of Infiltration practices Filtration is proposed in the following areas: • The infiltration basin, Infiltration Basin #1, is proposed in the southern portion of the property. 2. Existing Topography Existing topography in the proximity of Infiltration Basin #1 is approximately 2-3% slope. 3. Test Pit Location Three test pits were dug on the property, with one being in the vicinity of the Infiltration Basin. One field permeability test was completed in the vicinity of the Infiltration Basin. See grading and drainage plans as well as details. Proposed Dog Daycare and Grooming 260 Nutmeg Road South, South Windsor, Connecticut Infiltration Feasbility Report September 27, 2024 4. Season High Water Table Elevation Infiltration Basin #1: Bottom of Filtration Section Elevation = 67.33 High Contour Elevation (Existing) = 69.6 Groundwater Elevation = 64.93 Bedrock = None Found Bottom of Test Pit = 64.02 Separation to Bottom of Test Pit = 2.40’ 5. Infiltration Rate Study Infiltration rates for the Infiltration Basin were calculated by from field testing using a double ring infiltrometer. Testing was done in conformance with the 2024 Stormwater Quality Manual, Chapter 10, subsection Soil Evaluation Guidance. From the deep test pits, it was noticed the soil had a Sandy characteristics. The test came back with a 10.58 in/hr. Using a safety factor of 2 from the slower of the field tests, the infiltration rate utilized in the drainage analysis is as follows: • Infiltration Basin #1 = 5.288 in/hr 6.

Compliance with Stormwater Facility Maintenance Requirements The owner of the subject property is responsible for ensuring that stormwater facilities installed on the property are properly maintained and that they function as designed. In some cases, this maintenance responsibility may be assigned to others through special agreements. Any transfer of responsibility for inspection and maintenance activities or transfer of ownership shall be documented in writing. The contract documents will require the contractor to designate a person responsible for maintenance of the sedimentation control features during construction. Long- term operation and maintenance for the stormwater management facilities are presented below. II. Inspection & Maintenance – Annual Reporting Requirements for the inspection and maintenance of stormwater facilities, as well as reporting requirements, are included in this Stormwater Management Operation and Maintenance (O&M) Manual. Verification that the Stormwater facilities have been properly inspected and maintained; copies of the annual report should be documented on site for future reporting upon request. Copies of the Inspection and Maintenance forms for each of the stormwater facilities are located in Appendix B and C. A standard annual reporting form is provided in Appendix A. III. Preventative Measures to Reduce Maintenance Costs The most effective way to maintain your water quality facility is to prevent the pollutants from entering the facility in the first place. Common pollutants include sediment, trash & debris, chemicals, dog wastes, runoff from stored materials, illicit discharges into the storm drainage system and many others. A thoughtful maintenance program will include measures to address these potential contaminants and will save money and time in the long run. Key points to consider in your maintenance program include: • Educate property owners/residents to be aware of how their actions affect water quality, and how they can help reduce maintenance costs • Keep properties, streets and gutters, and parking lots free of trash, debris, and lawn clippings • Ensure the proper disposal of hazardous wastes and chemicals • Plan lawn care to minimize the use of chemicals and pesticides • Sweep paved surfaces and put the sweepings back on the lawn • Be aware of automobiles leaking fluids. Use absorbents such as cat litter to soak up drippings – dispose of properly O&M Manual ~ 2 ~ • Re-vegetate disturbed and bare areas to maintain vegetative stabilization. • Clean out the upstream components of the storm drainage system, including inlets, storm sewers, and outfalls • Do not store materials outdoors (including landscaping materials) unless properly protected from runoff IV. Access All stormwater management facilities located on the site have a designated access location. Refer to the Site Plan – Grading & Drainage Plan for access locations. V. Safety Keep safety considerations at the forefront of inspection procedures at all times. Likely hazards should be anticipated and avoided. Never enter confined space (outlet structure, manhole, etc) without proper training or equipment. A confined space should never be entered without at least one additional person present. If a toxic or flammable substance is discovered, leave the immediate area and contact the local authority at 911. Potentially dangerous (e.g., fuel, chemicals, hazardous materials) substances found in the areas must be referred to the local authority immediately for response. The emergency contact number is 911. Vertical drops may be encountered in areas located within and around the facility. Avoid walking on top of retaining walls or other structures that have a significant vertical drop. If a vertical drop is identified within the pond that is greater than 48” in height, make the appropriate note/comment on the maintenance inspection form. If any hazard is found within the facility area that poses an immediate threat to public safety, contact the local authority immediately. VI. Field Inspection Equipment It is imperative that the appropriate equipment is taken to the field with the inspector(s). This is to ensure the safety of the inspector and allow the inspections to be performed as efficiently as possible. Below is a list of the equipment that may be necessary to perform the inspections of all Stormwater Management Facilities: • Protective clothing and boots • Safety equipment (vest, hard hat, confined space entry equipment • Communication equipment O&M Manual ~ 3 ~ • Operation and Maintenance Manual for the site including stormwater management facility location maps • Clipboard • Stormwater Facility Maintenance Inspection Forms (See Appendix B) • Manhole Lid Remover • Shovel Some of the items identified above need not be carried by the inspector (manhole lid remover, shovel, and confined space entry equipment). However, this equipment should be available in the vehicle driven to the site. VII. Inspecting Stormwater Management Facilities The quality of stormwater relies heavily on the proper operation and maintenance of permanent best management practices. Stormwater management facilities must be periodically inspected to ensure that they function as designed. The inspection will determine the appropriate maintenance that is required for the facility. A. Inspection Procedures All stormwater management facilities are required to be inspected by a qualified individual. Inspections should follow the inspection guidance found in Appendix B of this manual. B. Inspection Report The person(s) conducting the inspection activities shall complete the appropriate inspection report for the specific facility. Inspection reports are located in Appendix B. VIII. Maintenance Requirements Stormwater management facilities must be properly maintained to ensure that they operate correctly and provide the water quality treatment for which they were designed. Routine maintenance performed on a frequently scheduled basis can help avoid more costly rehabilitative maintenance that results when facilities are not adequately maintained. The Long-Term Inspection and Maintenance Log provides a record of maintenance activities. Maintenance Logs for each facility type are provided in Appendix C. Catch Basins • Catch basins may require frequent maintenance. Depending on the location, this may require several cleanings of the sumps each year. At a minimum, it is recommended that catch basins be inspected at least twice annually, once following snowmelt and once following leafdrop. And cleaned as indicated by inspection. • Sediment should be removed when it approaches half the sump depth. O&M Manual ~ 4 ~ • If floating hydrocarbons are observed during an inspection, the material should be removed immediately by skimming, absorbent materials, or other method, and disposed in conformance with applicable state and federal regulations. • Cleaning may require vacuum-truck instead of “clam shell” to avoid damage to hood. • Damaged hoods should be replaced when noted by inspection. IX. Control of Invasive Species During maintenance activities, check for the presence of invasive plants and remove in a safe manner as described on the following pages. They should be controlled as described in Appendix D. Invasive plants are introduced, alien, or non-native plants, which have been moved by people from their native habitat to a new area. Some exotic plants are imported for human use such as landscaping, erosion control, or food crops. They also can arrive as "hitchhikers" among shipments of other plants, seeds, packing materials, or fresh produce. Some exotic plants become invasive and cause harm by: • becoming weedy and overgrown; • killing established shade trees; • obstructing pipes and drainage systems; • forming dense beds in water; • lowering water levels in lakes, streams, and wetlands; • destroying natural communities; • promoting erosion on stream banks and hillsides; and • resisting control except by hazardous chemicals.

Sheet ES1 provides project information that refers to phases of development, where Phase 1 is for the front building and parking lot construction and phase 2 is for the rear building. Clearly call these phases out on Sheet C1. 2. The 4-inch HDPE pipe from proposed infiltration basin is too small and will likely get clogged. Provide a larger outlet pipe, such as a 10 or 12-inch pipe with a 4” diameter orifice plate on the inlet end. Call this out on Sheet C2. 3. Show a spot elevation for the emergency overflow spillway from the proposed infiltration basin on Sheet C2. Please let me know if there are any questions. 1 Appl #24-44P, 260 Nutmeg Road South LLC Dog Daycare and Grooming – 260 Nutmeg Road South Public Hearing 12/10/24 Planning Department Report 1. This is a request for a special exception to 4.1.1A and site plan of development for a 5,183 sf facility for dog daycare and grooming, on property located at 260 Nutmeg Road South, I zone. 2. This application is subject to the review criteria of Section 8.4(B) which in clude that: • The proposal is consistent with the goals and objectives of the Plan of Conservation and Development; • The application has met the requirements of the zoning regulations; • The land is physically suited to the proposed use; • Minimal, if any, adverse environmental impacts are created; • No traffic or other hazards will be created; • The impacts on the capacity of the present and proposed utilities, street, drainage systems, sidewalks, and other elements of the infrastructure will be minimal ; • There will be minimal or no adverse effects on existing uses in the area; • Surrounding property values will be conserved; • The character of the neighborhood will be maintained or minimally disrupted ; • The general welfare of the community will be served; • There is a balance between neighborhood acceptance and community needs; • Historic factors are adequately protected; or due consideration to preservation of historic factors has been demonstrated; • The overall physical appearance of the proposed development is compatible with surrounding development and the Commission’s goals for the neighborhood/corridor ; • The architectural design is aesthetically pleasing and blends well into the surrounding area. 3. The specific criteria for Dog Grooming Facilities in Section 7.23 include: • Existing building must be free-standing; • Current building not suited for manufacturing; • Site location should not be disruptive to surrounding areas; 2 • Outdoor activities with animals must be within enclosed fenced areas. 4. The applicant’s narrative addresses our Special Exception criteria. It also provides a detailed description of how the business operates, how the site will be developed, and the anticipated impacts to traffic and the environment. 5. The narrative mentions that the business will be run and operated by the owner with no other employees, and that at one time there may be up to 30 dogs on the premises. I raise concern about the timely removal of dog waste if there is only one person to manage 30 dogs. 6. In 2006 this property was granted a 15’ variance to allow a 10’ rear yard setback (where 25’ is required) for new construction. The southwest property line is being designated as the rear yard. All building setbacks appear to comply. 7. Zoning requirements appear to have been met in the zoning information table on Drawing C1. Impervious surface is proposed to be 21%; 65% allowed. Proposed parking counts are shown as meeting our requirements, but without architectural floor plans it is difficult to verify how building square footage is being allocated. 8. The applicant has shown that the project will be broken out into 2 phases. A critical aspect of construction phasing is whether the individual phases can function on their own if one phase is never completed. Phase 1 will be constructed, and all operations will commence in the smaller building footprint. As demand of the services increase and expansion of the business becomes necessary, Phase 2 will be constructed. 9. Light levels in areas immediate to the proposed wall mounted fixtures appear to exceed the recommendations provided in Section 11.3 Appendix C of our Zoning Regulations. The applicant has made a good effort to keep light levels from spilling out to the wetland but should modify the intensity of the fixtures to provide an average light level of 0.8 footcandles. 10. The Inland Wetlands Agency and Conservation Commission approved this application at their 11/20 meeting with standard approval conditions including requiring the submission of a maintenance plan for the outdoor play area addressing how waste will be handled and kept out of the adjacent wetland area, and recommendation of $5,000 for erosion and sedimentation control and $7,500 for the establishment of stormwater structures. 11. A meeting with the Architectural Design and Review Committee is scheduled for 12/5. Staff will report back with updates. 12. WPCA approval is required. Engineering comments are as follows (read comments by Town Engineer). If this site plan modification is approved, Planning Staff has incorporated comments into the approval conditions.
