The total site area is 11.73 acres of which 5.97 acres (50.9%)has been delineated as inland wetland soils. The site has been used for agricultural purposes for many of the preceding years. As a part of this application, the developer proposes to mitigate development impacts to the existing wetlands by restoring the remaining wetlands to a higher value and function than they currently serve under agricultural use. Further the plan proposes to enhance existing wetlands by planting a diverse mix of wetland plant species. And finally the plan proposes to create new wetland areas to further mitigate the impacts to existing wetlands. Wetland delineations and environmental assessments have been prepared by Rema Ecological Services, Inc. Types of fill to be used in the development of parking drives and building areas are bank run gravel, structural fill, processed aggregate road base and bituminous concrete and concrete pavements. The following table outlines the amount of site disturbance to inland wetlands, and the proposed mitigations described above: Total site area = 11.73 acres = 510,958 SF Area of Inland Wetlands = 5.97 acres = 260,053 SF -- -- Area of regulated buffers = 2.22 acres = 96,800 SF Site%wetlands = 50.9 % Area of Wetlands to be altered by development=2.06 acres= 89,733 SF Area of Wetlands to be altered by enhancement= 1.75 acres =76,000 SF Total area of wetlands altered = 3.81 acres= 165,733 SF Area of wetlands to be restored = 2.05 acres= 89,298 SF Area of wetlands to be created = 1.10 acres=48,160 SF Net Wetland loss = 0.96 acres=41,817 SF Net Wetland restored, enhanced and created= 5.01 acres =218,236 SF ceW" sty ' `� !' wys a,—/� .Ci • U 1540 SULLIVAN AVENUE • SOUTH WINDSOR, CT 06074 '~OSOR-Co TELEPHONE (860) 644-2511 To: Anchor Engineering 75 Nutmeg Lane Glastonbury, CT 06033 From: Jeffrey H. Folger—Environmental Planner/Conservation Officer Date: June 18, 2002 Re: App. #02-34P - Review of the proposed South Windsor Health Center- Plans dated 6/12/02. I have reviewed the proposed plan with the following initial comments: The plans are not certified A-2. A professional engineer and a surveyor should certify them. An anti-tracking pad should be shown on the plans. Perimeter erosion controls are missing from the northern portion of the site associated with the 19,000-sqft building. They should be shown on the plans. A swale is proposed to be constructed along the northern portion of the site. This structure should have erosion controls placed at intervals along the length to prevent erosive cutting of the Swale bottom. Planting details for the swale nee to be submitted for review. The erosion control narrative is obscuring site information on page 5 of the plans. A drainage report has not been submitted for review by the Town Engineer. The project description is incorrect. Please include all proposed buildings shown on the plans. No erosion controls are proposed for the excavation on the eastern portion of the site. Trap hoods should be installed in proposed catch basins to capture floatables entering the storm system. Item#6 on the erosion narrative calls for temporary sediment pools to be installed. None are shown on the plan. } MEMORANDUM To: Jeffrey Folger, Environmental Planner/Conservation Officer CC: Marcia Banach, Director.of Planning From: Jeffrey B. Doolittle, P.E., Town Engineer en Date: 6/26/02 RE: App 02-34P, South Windsor Health Care Center I have reviewed the site plan (dated 6/21/02) for the South Windsor Health Care Center on Buckland Road and I have the following comments. 1. There is not A-2 Certification by a Licensed Surveyor on these plans. ✓2 The number of parking spaces required is not included on the Title Sheet. 3. The following surrounding properties are not listed correctly: 3a. The small parcel on the south west comer of this site does not have the current owners, and this property needs to be incorporated into Lot 1 (the lot line between them removed). There is an abutting property on the south east corner that is not listed. ,3c. The abutting property listed as N/F Johnny&Anne M. Jacques is not current. 3d. The Messiah Evangelical Lutheran Church has two abutting lots on the northern side. The lot lines between all abutting lots should be shown for clarity. �! I do not think Lot 3 will be allowed as it has no street frontage and there is no access easement. 5. On the Landscape plan, many of the plant symbols shown are not listed in the key. -The- tour--elevations should be turned off-on-this-plan. d 6. The Utilities & Drainage Plan does not show any utilities going into this site. The water, sewer, gas, electrical, telephone, cable and any other utilities need to be shown from the street to the buildings. Any off site sewer or drainage work needs to be included. 7. The proposed drainage system does not appear to be complete. Flar6d ends and rip rap plunge pools need to be shown in the detention basins. Why are there two drainage pipes crossing the driveway? The contours in the detention basins are not all labeled: What is the purpose of the small northern most detention basin?\Sggral of the catch basins should be relocated slightly for optimum performance and ease of maintenance. Additional catch basins may be required. CB #4 and #8 look like larger sedimentations structures. What are these structures? Where are the Roo!/Leaders and Foundation Drains and where will they discharge? r r 8. 1 have not received a drainage report or any hydraulic analysis to review so I can not check the sizing of pipes, placement of catch basins or sizing of the detention basins. Why are SNET poles 24, 25, 26 and 27 being moved? What are Note No. 2 and the Area of Taking Map Ref No. 4.? 10.The grading plan needs some revisions such as show contour 157 on the east side of the northerly building andLshow spot grades to verify there are not flat spots to the east of the buildings and in corner's of the parking lot. I believe the maximum grade allowable in HC parking areas is 2% in any direction. 11.Were any test pits or soil borings made on this site. This information needs to be included. 1 . !'strongly recommend underdrains and/or curtain drains be installed on the east side of the parking areas to catch water coming off the hill to the east. These can be piped to the nearest catch basins. 13. 1 have questions about the site layout. Why does the driveway begin at 36 foot width and narrow to 24 foot width? This should be a uniform width. Are all paved areas curbed? There should be a buffer strip or wider walk where there are parking spaces up against walks. What is the rectangle with corner elevations of 158.2, in the pavement to the south of the building on Lot 1? Are the walks concrete or bituminous? Will the sidewalk be flush with the pavement by the HC parking spaces? Will curb stops be provided? All lanes should be at least 24 feet wide. Parking spaces are shown as 9' x 18' which does not meet town standards. 4nclude a note that all construction shall be in conformance with the Town of South Windsor Public Improvement Specifications.4 In general these plans do not appear to be complete. I am available to sit down the Engineer to review my comments on these plans. Please call me (x 245) if you have any-- questions.

Folger—Environmental Planner/Conservation Officer Date: June 27, 2002 Re: App. #02-34P - Review of the proposed South Windsor Health Center- Plans dated 6/12/02. I have reviewed the proposed plan with the following additional comments: To date, we have not received an environmental assessment of the wetlands present, or the proposed mitigation scheme. Details of the proposed planting plan should be provided. These should include seed and plant types and quantities, and planting bed details. The plan shows excavated areas at the toe of the slope on the eastern portion of the site. How will those areas be accessed? What measures will be proposed to minimize disturbance to wetland areas in between? Item #6 of the.Sediment control requirements mentions utilizing temporary sediment pool when de-watering excavations. Please provide a detail of the temporary sediment pool with the appropriate outlet. The soil types shown on the plans are incorrect. Enfield and Tisbury soils are not wetland soils. Temporary and permanent seeding types, rates, and dates need to be shown on the plan. The sequence of construction does not include the installation of the proposed detention basins. These should be installed and stabilized prior to stormwater being diverted into them. This should appear in the sequence narrative. CC. Dir. Of Planning Town Engineer Inland Wetland/Conservation Commission RECEIVED JUL 10 Z002 ' SOUTH WINDSOR PLANNING DEPT, Stormwater Management Report ' for South Windsor Healthcare Center 1 July 2002 1 1 ' Anchor Engineering Services, Inc. 75 Nutmeg Lane Glastonbury, Connecticut 06033 ' Tel: (860) 633-8770 Fax: (860) 633-5971 ' Table of Contents ' A. Project Description B. Existing Drainage System 1 C. Proposed Drainage System ' D. Erosion and Sedimentation Control Plan ' Appendices ' I. Drainage Area Map II. Drainage Computations III. Detention Basin Computations (Pond Pack Report) Project Description Sargis Construction is proposing the subdivision of an 11.73-acre parcel of land located to the East of Buckland Road in South Windsor, Connecticut. The existing ' parcel is in the Gateway Development Zone and will be subdivided to create three separate, conforming lots. Lot 1 is 5.07 acres and will be developed to create the ' South Windsor Healthcare Center. Lot 2 is 4.30 acres with the potential for future ' commercial or industrial development and Lot_3 is'736.acres and will be attached to the abutting property now or formerly of Johnny &Ann A Jacques to the east of the ' existing site. Existing Drainage On-Site drainage is indicative of the existing soil types, which have been determined through test pit observation and available soil type maps of Hartford County. The eastern third of the property consists of steep slopes and relatively ' well-drained soils. The middle third of the existing site is designated as wetland soils, which are poorly drained, and finally the western third of the property ' consists of well-drained soils. Stormwater is handled on site through sheet flow and channel flow to an existing outfall located along Buckland road on the ' western property line of the existing site. The existing outfall is a 24" reinforced concrete flared end which leads to an existing drainage system to the west of the ' property. ' Proposed Drainage The proposed drainage system has been designed in accordance with the Town of South Windsor Regulations, current engineering practices, and the need to meet a zero net increase in stormwater runoff from the site. Drainage structures and pipes have been designed to sufficiently pass a 25-year frequency storm without ' overtopping and the detention basins have been designed to store a 100-year storm event with zero net increase in runoff to the existing drainage system. Drainage has been designed and provided on the proposed site to accommodate ' runoff generated by undeveloped lands, developed areas, and groundwater flows. All stormwater runoff generated.from the undeveloped lands on the east side of Lots t1 and 2 will be diverted to the north by means of grass swales. The swales lead to a 15" reinforced concrete flared end located at the northwest corner of Lot 2. This ' water will then be directed to the existing outfall without the need for treatment, which eliminates extra costs and additional site work necessary with treatment. All ' developed areas such as buildings, sidewalks, paved areas, etc. will be directed through a system of drainage structures, treatment structures, and detention basins. ' Groundwater flows will be intercepted at the east side of the developed areas through underdrains. These underdrains will be connected to the existing drainage system. ' Sediment carried with the first inch of stormwater runoff will be handled in a multiple step process. The two main drainage systems proposed on the site will be ' routed through Vortechnics Stormwater Treatment Systems, which have been designed to accommodate all flows within the system during a 25-year storm event. Any sediment not removed by the Vortechnics System will be directed to a detention basin. Each on-site detention basin has been designed to store the first inch of ' stormwater generated by proposed impervious surfaces before it enters the existing outfall. Therefore, with proper maintenance of the Vortechnics stormwater ' treatment structures and detention basins, sediments generated by the proposed development should not enter the existing drainage system. ' Erosion & Sediment Control Plan The potential impact of the project on the surrounding areas is related to the temporary transport of soils and sediments associated with the construction phases of the project. The impact of the project on the surrounding areas will be controlled ' as follows: 1. All erosion and sediment control measures will be installed at the project site ' prior to construction. ' 2. An Anti-Tracking Apron will be installed at the entrance to the construction site in order to prevent the transport of sediments off the construction site by ' truck and construction equipment traffic. ' 3. An erosion control system will be installed around the construction area as detailed on the site plan. 4. All catch basins within the project area will be protected with hay bales ' throughout the construction period. These hay bales will remain in place until the areas disturbed during the construction phase are stabilized. 5. An erosion control system shall be installed around all on-site stockpiles of ' soil. 6. Dust control measures shall be applied throughout the construction period ' and until all disturbed areas have been stabilized. ...� 'C C d� � � � � � � � � � � � � � � � � � S � ' Appendix 11 1 1 1 1 1 1 PIPE FLOW ANALYSIS -25 YEAR Prepared for: South Windsor Medical Center Location: South Windsor,CT 5/28/02 Z n > C D C m C D -n -n < � m m C D p Z -n N m 0 Do m p r- c z p Z C D T m { N = m 0 _ < = 2 m r- Cn m p Z D z m m -n < D O 3 CO m m m G1 z m 0 n -� _> j z m CA o m m Z m N .- Ul m m D MIN.

Doolittle, P.E., Town Engineer Date: 7/18/02 RE: App 02-34P, South Windsor Health Care Center I have reviewed the revised site plan (dated 7/11/02) for the South Windsor Health Care Center on Buckland Road and I have the following comments. 1. There is still no A-2 Cerfification by a Licensed Surveyor on these plans. 2. The small parcel on the south west comer of this site does not have the current owners, and this property needs to be incorporated into Lot 1 (the lot line between them removed). 3. The Messiah Evangelical Lutheran Church has two abutting lots on the northern side. The lot lines between all abutting lots should be shown for clarity. 4. On the Landscape plan, many of the plant symbols shown are not listed in the key. 5. The Utilities & Drainage Plan needs to include the gas, electrical, telephone, cable and any other utilities from the street to the buildings. Where will the sewer line go from this site as there is not any existing sewers in this portion of Buckland Road? Any off site sewer or drainage work needs to be shown. 6. On the proposed drainage system: Can the two drainage pipes crossing the driveway be combined? What is the purpose of the small northern most detention basin? Several of the catch basins should be relocated slightly for optimum performance and ease of maintenance. Additional catch basins may be required. Where are the Foundation Drains and where will they discharge? 7. With regard to the Stormwater Management Report: The disposition of the eastern 2.36 acres as stated under the Project Description (last sentence) does not agree with a note on the Sheet 1 of these- plans. A more thorough description of the flow path for stormwater from the eastern portion of these lots is necessary. The description in the Proposed Drainage section and contours on the plan are not clear. Draining of additional stormwater to adjacent properties that are not part of this site plan will not be allowed without specific easements and provisions to handle these flows. Provide a table comparing existing flows and post development flows from this site for various storm events. The roof leader that drains to CB 4 appears to be undersized. No flows are included for the area of the large detention basin to the north of the driveway. Additional tables and descriptions are required to explain the design flows to and from the detention basins and the required storage volume for various storm events. The computer program printouts need further clarification and explanation. Will there be standing water in the proposed detention basins? How will these be maintained so they present an attractive frontage to this development? A gutter flow analysis should be done to determine if any of the catch basins (especially in the driveway) require double inlet grates. 8. The grading plan needs some spot grades to verify there are not flat spots to the east of the buildings and in corners of the parking lot. I believe the maximum grade allowable in HC parking areas is 2% in any direction. 9. Were any test pits or soil borings made on this site. This information needs to be included. 10. 1 have questions about the site layout. Why does the driveway begin at 36 foot width and narrow to 24 foot width? This should be a uniform width. Are all paved areas curbed? There should be a buffer strip or wider walk where there are parking spaces up against walks. What is the rectangle with corner elevations of 158.2, in the pavement to the south of the building on Lot 1? Are the walks concrete or bituminous? Will the sidewalk be flush with the pavement by the HC parking spaces? Will curb stops be provided? All lanes should be at least 24 feet wide. Parking spaces are shown as 9' x 18' which does not meet town standards. Please call me (x 245) if you have any questions. ,n 1 a I I! ✓ryFAQV4'�cc2 I O AT CH tOTAL D AINAGE AREA �'• ^:. 4,99300 SO.

I have reviewed the proposed plan with the following initial comments: Lk') The plans are not certified A-2. A professional engineer and a surveyor should certify them. anti-tracking pad should be shown on the plans. ,,Wrimeter erosion controls are missing from the northern portion of the site associated with the 19,000-sqft building. They should be shown on the plans. A swale is proposed to be constructed along the northern portion of the site. This structure NOD should have erosion controls placed at intervals along the length to prevent erosive cutting of the swale bottom. Planting details for the swale need to be submitted for review. /The erosion control narrative is obscuring site information on page 5 of the plans. A drainage report has not been submitted for review by the Town Engineer. ,,The project description is incorrect. Please include all proposed buildings shown on the plans. Ao erosion controls are proposed for the excavation on the eastern portion of the site. tP Trap hoods should be installed in proposed catch basins to capture floatables entering the storm system. y Item #6 on the erosion narrative calls for temporary sediment pools to be installed. None are �N shown on the plan. �f1?'D 1 Erosion controls should be installed east of the detention basins to prevent sediment migration into finished basins. Replace the proposed type II sediment structure with a more efficient structure (Baysaver, �Vortecs, etc). v Sediment foreba s need to be installed in the detention basin to capture and contain sediment. Y p An operations and maintenance schedule needs to be developed that will address periodic removal of sediments. The Upland Review Area shown on the plans is incorrect. The distance from wetlands should be Cls�° eighty (80) feet. This needs to be changed on the plans. The applicant is responsible to demonstrate that the proposed plan represents the most feasible and prudent alternative to disturbing the wetland.

There is not A-2 Cerfification by a Licensed Surveyor on these plans. 2. The number of parking spaces required is not included on the Title Sheet. 3. The following surrounding properties are not listed correctly: 3a. The small parcel on the south west corner of this site does not have the current owners, and this property needs to be incorporated into Lot 1 (the lot line between them removed). 3b. There is an abutting property on the south east corner that is not listed. 3c. The abutting property listed as N/F Johnny&Anne M. Jacques is not current. 3d. The Messiah Evangelical Lutheran Church has two abutting lots on the northern side. The lot lines between all abutting lots should be shown for clarity. 4. 1 do not think Lot.3 will be allowed as it has no street frontage and there is no access easement. 5. On the Landscape plan, many of the plant symbols shown are not listed in the key. The contour elevations should be turned off on this plan. 6. The Utilities & Drainage Plan does not show any utilities going into this site. The water, sewer, gas, electrical, telephone, cable and any other utilities need to be shown from the street to the buildings. Any off site sewer or drainage work needs to be included. 7. The proposed drainage system does not appear to be complete. Flared ends and rip rap plunge pools need to be shown in the detention basins. Why are there two drainage pipes crossing the driveway? The contours in the detention basins are not all labeled. What is the purpose of the small northern most detention basin? Several of the catch basins should be relocated slightly for optimum performance and ease of maintenance. Additional catch basins may be required. CB #4 and #8 look like larger sedimentation structures. What are these structures? Where are the Roof Leaders and Foundation Drains and where will they discharge? 4 8. 1 have not received a drainage report or any hydraulic analysis to review so I can not check the sizing of pipes, placement of catch basins or sizing of the detention basins. 9. Why are SNET poles 24, 25, 26 and 27 being moved? What are Note No. 2 and the Area of Taking Map Ref No. 4.? 10.The grading plan needs some revisions such as show contour 157 on the east side of the northerly building and show spot grades to verify there are not flat spots to the east of the buildings and in corners of the parking lot. I believe the maximum grade allowable in HC parking areas is 2% in any direction. 11.Were any test pits or soil borings made on this site. This information needs to be included. 12. 1 strongly recommend underdrains and/or curtain drains be installed on the east side of the parking areas to catch water coming off the hill to the east. These can be piped to the nearest catch basins. 1.3. 1 have questions about the site layout. Why does the driveway begin at 36 foot width and narrow to 24 foot width? This should be a uniform width. Are all paved areas curbed? There should be a buffer strip or wider walk where there are parking spaces up against walks. What is the rectangle with corner elevations of 158.2, in the pavement to the south of the building on Lot 1? Are the walks concrete or bituminous? Will the sidewalk be flush with the pavement by the HC parking spaces? Will curb stops be provided? All lanes should be at least 24 feet wide. Parking spaces are shown as 9' x 18' which does not meet town standards. Include a note that all construction shall be in conformance with the Town of South Windsor Public Improvement Specifications. In general these plans do not appear to be complete. I am available to sit down the Engineer to review my comments on these plans. Please call me (x 245) if you have any questions. MEMORANDUM To: South Windsor Inland Wetland/Conservation Commission. From: Jeffrey H.H Fol er Zoning/Wetland Enforcement Officer g - Date: June 27, 2000 Re: Review of the ro p posed South Windsor Health Care Center Site plan. Plans dated 06/12/02. The project is to create a three-lot subdivision and two office buildings and parking for 223 P J g P g spaces on approximately 11.75 acres. Proposed regulated activities include filling approximately 2.06 acres of wetland, approximately 2.22 acres.of regulated upland review area. Site: The site is located in the Podunk River watershed and Plum Gully Brook sub-watershed. The parcel is comprised of 11.75 acres. Drainage flows east to west to a culvert that goes under Buckland Road and discharges on the property to the west. Currently the site is a combination of early to mid successional forest on the eastern slope(1/4 of the site) and former cultivated fields extending to Buckland Road. Three linear hedgerows break up the fields perpendicular to the road. Historically, the site has been intensively farmed. Hydrology on the site appears to be the result of groundwater breaking out from the eastern ridge causing the center half of the property to be seasonally saturated. The hedgerows appear to be associated with historical drainage ditches. Currently the center hedgerow does contain a watercourse. Two areas containing wetland soils occur on the site. The central `/2 of the site is mapped as wetlands and there is a watercourse with associated wetlands located in the northeast corner of the site also. These wetlands are a part of a larger wetland band that extends north to south from Deming Road to the Manchester town line. The vegetation on the parcels in this band range from thick successional shrub to wet meadow. The second wetland area occurs in the northeast corner of the site and is in the form of a perennial brook that flows to the northwest toward Sele Drive. No development is proposed in this area, although it is shown as a lot on the plan. The central wetland would be categorized as a disturbed site due to past agriculture activities. The hedgerows exhibit shrub and some mature tree growth. The past-cultivated areas (4-5 years ago) are quickly reverting back to a wetland ecosystem. Sedges and rushes (early colonizers) are flourishing among remnant hay grass species. Major functions of this wetland would be stormwater conveyance, groundwater recharge, and wildlife habitat, with nutrient assimilation, and sediment retention as lesser values. Wildlife habitat values for this wetland area by itself would be considered moderate due to the diverse mixture of habitat types present on the property. Past agricultural use has retarded the succession of wetland plants in the open areas, however many wetland species are re-colonizing the area. The wetland area of the parcel to the north is comprised of a heavy stand of shrub growth, primarily dogwood and red maple. Although a virtual monoculture, the wildlife food and cover value would be considered moderate to high on these northern parcels. The proximity of these parcels to the subject parcel would tend to increase the value.of the subject parcel and any potential enhancement of the subject parcel's present flora. Impacts: Erosion and sedimentation: The soils onsite are identified by the Hartford County Soil Survey as Tisbury Silt Loam(TsA) 0- 3% slopes,Narragansett Silt Loam(NaB) 3-8% slopes, Tisbury Silt Loam(TsB) 3-8% slopes, and Walpole Loam(WcA) 0-3% slopes. The Narragansett soils are shown to occur on the eastern slopes. The current plan shows the soils on the site as being Enfield Silt Loam (EsA) 0-3% slopes, Enfield Silt Loam(EsB) 3-8% slopes, Tisbury Silt Loam(TsB) 3-8% slopes, and Enfield Silt Loam (EsQ 8-15% slopes. None of these soils are considered a wetland soil. I have asked the applicant to review this portion of the plan. Erosion potential of the Enfield soils is listed as high. The neighboring properties to the west and Plum Gully Brook are in a position to be impacted by migrating sediments. Perimeter controls and an anti-tracking pad have been proposed. With proper maintenance these controls will be effective in preventing the migration of most of the sediment generated by construction activities. However the silty material present in the soil will remain in suspension longer than the proposed structures are capable of retaining and will be discharged offsite. Additional temporary retention is necessary to minimize impacts to Plum Gully Brook during construction. The current plans need to be modified to address anticipated water flow onto the site from upslope during the initial phases of construction. Stormwater Management: Stormwater quantity and quality impacts are proposed to be managed by a catchbasin system draining to two wet bottom detention basins. Proper sizing of the basins has not been determined due to the lack of a submitted drainage report by the applicant. It is recommended that trap 4 hoods be installed in the catchbasins to intercept and contain floatables (including hydrocarbons). It has also been recommended that the gross particle separator(a type II sediment chamber) be replaced by a more efficient structure. Detailed plans have been requested pertaining the sizing and interior features of the basins. Wildlife habitat: The hedgerows presently offer favorable roosting and cover sites as well as limited food value. Numerous wildlife trails are present heading from hedgerow to hedgerow. It is also apparent that the wooded slope area on the eastern portion of the parcel is utilized by wildlife, and there are signs that wildlife travel from the wooded slope area to the wetland area. The wooded slope area is a part of a continuous wooded ridge that runs from this site south to Buckland Hills Drive. The wildlife value in the open areas has increased over the last few years due to the colonization of wet meadow plant species in former cultivated fields. A large quantity of"edge"habitat currently exists at the interface of the fields and the hedgerows and forest. Mitigation: The current plans show the proposed regulated area disturbances to be mitigated by altering and enhancing the wetland areas to the east of the rear parking areas. Four shallow marsh areas are proposed to be excavated on the site. Two immediately east of the proposed parking lots, and two in the eastern portion of the site at the toe of the slope and planted with wetland plants. The previously cultivated open areas are proposed to be enhanced by re-planting the areas with a more diverse wet meadow seed mix. Although the plans do not specify this, conversations with the applicant indicate that this will be done by plowing up the existing areas and re-seeding. This might have been appropriate five years ago when the fields were recently disturbed, but given the level of re-colonization by wet meadow plant species,this plan will unnecessarily disturb wetland areas that are well along in the successional process. An acceptable alternative that would minimize large-scale disturbance would be to mow strips in the fall and drill the seed in the fields. The installation of the marsh areas and enhancement plantings has the potential of increasing the habitat diversity and the opportunity for increasing the number species of wildlife to utilize the property. A plant type key is absent from the plans so I cannot determine what is proposed to be planted in the mitigation areas. The applicant has stated that wetland creation proposed equals 1.1 acres or 48,160 sqft. My estimation of the wetland proposed to be created that is not directly related to.the detention basins along Buckland Road is 7,000 sqft. The applicant's estimation of the net wetland loss after mitigation is .96 acres.

Several of the catch basins should be relocated slightly for optimum performance and ease of maintenance. Additional catch basins may be required. Where are the Foundation Drains and where will they discharge? 7. With regard to the Stormwater Management Report: The disposition of the eastern 2.36 acres as stated under the Project Description (last sentence) does not agree with a note on the Sheet 1 of these plans. A more thorough description of the flow path for stormwater from the eastern portion of these lots is necessary. The description in the Proposed Drainage section and contours on the plan are not clear. Draining of additional stormwater to adjacent properties that are not part of this site plan will not be allowed without specific easements and provisions to handle these flows. Provide a table comparing existing flows and post development flows from this site for various storm events. The roof leader that drains to CB 4 appears to be undersized. No flows are included for the area of the large detention basin to the north of the driveway. Additional tables and descriptions are required to explain the design flows to and from the detention basins and the required storage volume for various storm events. The computer program printouts need further clarification and explanation. Will there be standing water in the proposed detention basins? How will these be maintained so they present an attractive frontage to this development? A gutter flow analysis should be done to determine if any of the catch basins (especially in the driveway) require double inlet grates. 8. The grading plan needs some spot grades to verify there are not flat spots to the east of the buildings and in corners of the parking lot. I believe the maximum grade allowable in HC parking areas is 2% in any direction. 9. Were any test pits or soil borings made on this site.
