The improvements to the schools will consist of adding parking lots, upgrading recreation fields and construction of ' utlities and additions to the buildings. The proposed drainage system will collect and route runoff from the site improvements with combination of roof leaders, yard drains and catch basins that discharge the storm water to Plum Gulley Brook. The hydraulic analysis for this system is based on a 10 year return frequency storm in ' accordance with the Town of South Windsor' s "General Storm Drainage Design Guidelines" distributed by the South Windsor Public Works Department to design engineers. A hydrologic ' Analysis of the Plum Gulley Brook watershed was also requested by the Town of South Windsor Engineering and Public Works Departments to insure that the increased development of the school 's site would not create any adverse impact due to an increase in flow rate or water surface elevations at the downstream road crossings at Sand Hill Road, Ellington Road (Conn. Rte. 74) , and Oakland Road (Conn. Rte. 30) . ' This report consists of a gutterflow, pipe capacity, and a headwater analysis for the school drainage system. The Plum ' Gulley Brook hydrologic analysis demonstrates pre and post development flow rates and water surface elevations at the school driveway and the above mentioned road crossings for multi-frequency storms ranging from the 1 to the 100 year ' return frequency rainfall events. �l SUMMARY The subject site of the South Windsor High School on ' Nevers Road in South Windsor, Connecticut is located in the 687 acre Plum Gully Brook Watershed. The proposed improvements to' the South Windsor High School will occur on ' approximately 29 . 7 acres of this watershed. The net increase of impervious area to the site will be 7 . 6 acres from the building additions and parking lot. This increase in ' development corresponds to an increase in rainfall runoff of approximately 20 cfs for the twenty five year return frequency storm. The site storm drainage is designed for a 25 yr capacity and discharges to Plum Gully Brook The overall effect of the increase in runoff on downstream structures is diminished substantially by the position of site in the lower third of the major contributing area of the Plum Gully Brook watershed. The effect of the High School development on the flow in the Plum Gully Brook is analyzed at four major road crossings; a 72" RCP culvert in the High School driveway, a 3 ' x 6 ' box culvert in Sand Hill Road, a 42" CMP culvert in Ellington Road (Conn. RTE 74) , and a 48" RCP culvert in Oakland Road (Conn. RTE 30) . The average peak increase at all the crossings for the 1, 2, 5, 10, 25, 50 and 100 year storm events is 1. 2 cfs. The largest peak increase is 2 . 7 cfs (1. 2%) for the 25 yr storm at the 48" RCP at Oakland Road. The peak discharge for the 100 year storm at the 72" RCP culvert is decreased by 2 .2 CFS. The average increase of water depth at all formerly mentioned storms and all routed design points is 0. 02 ft with the maximum increase of 0. 07 ft at the 42" CMP at Ellington Road for the 2 year storm and the 3 ' x 6 ' box culvert in Sand Hill Road for the 10 yr storm. The depth of flow during the 100 year storm at the ' 72" RCP culvert is decreased by 0. 02 ft. A summary of all calculated flows and elevations at routed structures is included in this report. The pre-development analysis indicates that each of the ' road crossings will flood during a given storm. The 72" RCP in the High School driveway floods for the 100 yr storm, the 3 ' x 6 ' box culvert floods for the 25 yr storm and the 42" CMP floods for the 5 year storm. The storm flows were not routed through 48" RCP in Ellington Road in this analysis. Would detention of the increased peak flow on the high school site improve the situation? An analysis of the hydrographs at the High School culvert indicates that the High School storm runoff peaks approximately 2 hrs before the larger watershed peak. The early runoff response of the ' site results with only the receding limb of the site hydrograph contributing to the peak discharge for the entire watershed. A detention facility functions by holding back the water and slowly releasing it. This serves to increase the runoff volume under the receding limb of the hydrograph. Detention would increase the overall watershed peak, because ' the receding limb of the hydrograph is the only contributing element of the High School runoff to the larger watershed peak. The pre and post development hydrographs for the 25 yr return frequency storm are included in this report. METHOD ' The SCS TR-20 and TR-55 computer programs were used to analyze the pre and post development storm water flows. The contributing portion of the site is approximately 30 acres in a 687 acre watershed. This watershed was divided into six subareas analyzed at five design points with the watershed characteristics listed as shown on the map on page 5 of this report. A watershed routing schematic is included in this report on page 6. The first design point is a detention facility for the Windshire-Abbe development.The watershed runoff is routed through the weir structure of the detention facility and through a channel reach to Nevers Road. The runoff is then routed through a second reach to the second design point, a 72" RCP in the High School driveway. At the second design point three hydrographs are added; the reach routed hydrograph, a portion of the High School runoff hydrograph and the remaining watershed hydrograph. These flows are then routed through the 72" RCP culvert. The outflow hydrograph from the 72" RCP is routed through a third channel reach to the third design point which is the 31x 6 ' box culvert in Sand Hill Road. The remaining portion of the High School runoff is contained in. the watershed contributing to the flow at the box culvert. This flow is added to the reach routed hydrograph from the 72" RCP. The hydrograph is then routed through the box culvert and a fourth reach to the ' fourth design point, a 42" CMP in Ellington Road. The routed hydrograph is added to the remaining watershed and routed through the 42" CMP to the fifth and last design point, a ' 48" RCP in Oakland Road. The discharge from the 42" CMP is added to the remaining watershed hydrograph to formulate the total watershed hydrograph. The watersheds were delineated from both a U.S.G.S 2000 ' scale map and the town topographic maps which were verified with field trips to the area. The soils groups were determined by using a S.C.S soils map for Hartford County. The channel discharge-area curves and flow line elevations ' were interpolated from 100 scale town topographic maps. Flow overtopping the roads was considered broad crested weir flow. Outlet discharge-stage curves were calculated for the structures downstream of the school site. ' The site storm drainage was designed using Conn. D.O.T. Drainage Manual procedures for the 10 yr return frequency storm. Modified rip rap channels were designed from the outlets of the onsite drainage facilities to the Plum Gully Brook channel. The U.S. Dept. of Transportation Hydraulic Design Series No. 3 and No. 11 were used as a guideline for this design. The combination of steep slopes and easily eroded silty loam soils necessitated the use of rip rap channels. /ram SUMMARY TABLE 3 - DISCHARGE (CFS) AND ELEVATIONS (FT) FOR STRUCTURES FOR ALL STORMS STRUCTURE STORM NUMBERS..........

The purpose of my visit was to identify the inland wetland boundaries. The fieldwork was done on July 21, 1989. The wetland boundaries are marked with blue flagging numbered WL-1 through WL-71. Please refer to the enclosed sketch for the approximate location of the inland wetland boundaries and key wetland flag numbers. The soil map and narrative are a refinement of data contained in the Soil Survey of Hartford County, Connecticut. The symbols on the map identify map units. Each map unit has a unique combination of soils. Areas with the same symbol have similar composition. The following map unit descriptions are based on the data collected at this particular site. For this reason, there may be some differences between these descriptions and those provided in the Soil Survey of Hartford County, Connecticut. The identification of the wetlands was based on my field observations of the soils on this site and the guidelines of the National Cooperative Soil Survey Program. The non-wetland soils were not studied in detail . Observations were made of these soils only in the process of identifying the wetland sites. The following descriptions do not constitute a detailed soil survey, but may be used as an aid in site planning. WETLAND SOILS Map Unit Am e m complex map unit consists primarily of poorly and very poorly drained, loamy alluvial soils and moderately well , and well drained loamy alluvial soils on 0 to 3 to percent slopes. These very deep soils formed in recent alluvial sediments on floodplains. Typically, they have silt loam, loam, fine 'sandy loam, or sandy loam textures. The poorly and-very poorly drained soils (FTuvaquents) have a seasonal watertable at a depth of 0 to 1.5 feet. The moderately well drained and well drained (Udifluvents) have a seasonal watertable at a depth greater than 1.5 feet. These soils are subject to frequent or very frequent flooding. They are inland wetland soils. Map Unit WcA The WcA map unit consists primarily of Raypol soils on 2 to 5 percent slopes. Raypol soils are very deep, poorly drained soils, formed in loamy over sandy and gravelly glacial outwash deposits. These soils have a watertable within 1.5 feet of the surface much of the year. Typically they have a silt loam, very fine sandy loam, or fine sandy loam surface layer and subsoil over a stratified sand and gravel substratum that extends to a depth of 60 inches or more. They are inland wetland soils. NON-WETLAND SOILS Map Unit EsA fiFe—Es map unit consists primarily of Haven soils on 2 to 8 percent slopes. These very deep well drained soils formed in loamy over sandy and gravelly glacial fluvial deposits. Typically they have a silt loam, loam or very fine sandy loam surface layer and subsoil over a stratified sand and gravel substratum. Map Unit NnA 7H_e_lTn7 map unit is composed of Ninigret soils on 0 to 3 percent slopes. These soils are very deep and modertely well drained. Ninigret soils formed in glacial outwash. Typically, they have a fine sandy loam surface and subsoil layer, overlying sand and gravel to a depth of 60 inches or more. Ninigret soils have low chroma mottles within a depth of 24 inches. These soils have a seasonally high watertable at 1.5 to 2.5 feet from late fall to early spring. Map Unit UDB 7Fe__M map unit consists primarily of man-made cut and/or fill areas. Slopes range from 0 to 8 percent. The fill is mostly earthy materials with minor amounts of non-earthy materials such as pieces of concrete, bricks, wood, metals and glass. In cut areas the natural soil has been excavated and the unconsolidated loamy glacial deposit is exposed. F' Map Unit UDC e UDC map unit consists primarily of man-made cut and/or fill areas. Slopes range from 8 to 15 percent. The fill is mostly earthy materials with minor amounts of non-earthy materials such as pieces of concrete, bricks, wood, metals and glass. In cut areas the natural soil has been excavated and the unconsolidated loamy glacial deposit is exposed. Map gnit UDD e UUD map unit consists primarily of man-made cut and/or fill areas. Slopes range from 15 to 25 percent. The fill is mostly earthy materials with minor amounts of non-earthy materials such as pieces of concrete, bricks, wood, metals and glass. In cut areas the natural soil has been excavated and the unconsolidated loamy glacial deposit is exposed. A narrow intermittent watercourse was flagged with red flagging numbered 1 through 4. It is shown on the sketch map. Please contact me if you have any questions or if I can be of further assistance. Respectfully ,,yours, Roy A.

Fitts, Chairman Public Building Commission 239 Oak Street South Windsor, CT 06074 Dear Mr. Fitts: Re: South Windsor High School Addition As clarification to meetings which Town staff have attended with the high school design consultants, I would like to offer the following comments and information. It is my understanding that the Public Building Commission is anticipating construction on the above-referenced project this spring. To that end, I would like the Public Building Commission to be aware of -the various regulatory agency schedules and procedures so this important project can be expedited through the system. As there are regulated wetlands on site, the application must be approved by the Inland Wetlands Agency/Conservation Commission prior to action by the Planning and Zoning Commission. (This is mandated by State Statute, therefore out of our control. ) The Inland Wetlands Agency/Conservation Commission meets twice monthly, on the second and third Mondays of the month. Applications must be submitted fourteen (14) working days in advance- of the first monthly meeting in order to be officially received by that Agency. The Planning and Zoning Commission meets generally every - Tuesday but officially receives applications on the fourth Tuesday of each month. Application should be submitted two weeks prior to the fourth Tuesday of the month in which the application is to be officially received. The application to the Planning and Zoning Commission is a Special Exception application,._and--therefore requires a public hearing (again, statutorily mandated) . Public hearings take about three weeks to schedule, due to legal notice advertising time frames . While the Planning and Zoning Commission cannot take action on your application until Inland Wetlands Agency/Conservation Mr. Howard E. Fitts Page Two March 23, 1990 Commission acts, Planning and Zoning can hold the public hearing while the Inland Wetlands Agency/Conservation Commission application is pending, thereby allowing the Planning and Zoning Commission to act expeditiously upon receipt of the Inland Wetlands Agency/Conservation Commission's decision. Upcoming application receipt dates and submission dates are: Inland Wetlands Commission April meeting: Application submission by March 23; officially received April 16; action subsequent to April 16 . May meeting: Application submission by April 24; officially received May 14 Planning and Zoning Commission April: Application submission by April 10: Officially received April 24; public hearing, action subsequent to April 24 May: Application submission by May 8; officially received May 22 You should also be aware that, in a public project as large as this one, a substantial amount of town staff review time- is required, with particular emphasis on p project engineering. our ability to perform timely reviews is controlled completely by the timing and content of plans submitted to us. To date, our involvement in the engineering aspects of the project has been very limited because of the general (rather than detailed) nature of the information submitted to us . A further complication is introduced via the arrangement whereby our main consultant contact is the project architect rather than the project engineer. Finally, our ability to expedite an application through the regulatory system is greatly increased when an application is complete in accordance with the zoning- and inland wetlands regulations. If sections of the regulations are not adhered to, particularly with respect to items required to be shown on plans or documents to be submitted with the application, staff review time may be interrupted while waiting for the necessary information to be submitted. Therefore we urge careful attention to the regulations when the regulatory applications are being prepared. Y- Mr. Howard E. Pitts Page Three March 23, 1990 Our objective for the high school addition is to work with you as closely as possible, And to give you our full cooperation to ensure that this project is able to be constructed in a timely manner.

Lombardi, Chairman, Inland Wetlands Agency/Conservation Commission FROM: John E. McCahill, Zoning/Wetlands Enforcement Officer RE: Application #90-24P, South Windsor High School DOCUMENTS REVIEWED: Application form, plans for Additions and Alterations to the South Windsor High School and Wapping Elementary School, and Storm Water Hydrologic and Hydraulic Analysis. COMMENTS: 1 . This review was started based on plans with the latest revision date 3/30/90. The plans as revised 4/11/90 were also reviewed and the following comments still apply. The revisions of 4/11/90 included adding riprapped plunge pools and reduced the size of topsoil storage area #2. Sheet L- 10 was not submitted as part of the revision. This should be included. 2. The wetlands have been field located by Roy A. Shook, Jr. , of Environmental Resource Associates . A report of his findings should be submitted and he should verify the limits as shown on the plans. The area is part of the Plum Gulley Brook. One of the wetlands soils is identified as WcA. They indicated that this is "Raypol" . This should be modified to read Walpole. 3. At the time of my review the application form did not indicate that abutters had been notified. I contacted the applicant and he stated it was done and a copy of the letter and proof of notification will be submitted. 4. The total percentage of impervious area should be identified on the plans. 5 . Sheet L-4 contains three portions of the total site. Match lines have been provided on the plans but they are difficult to interpret. James A. Lombardi Page Two April 11, 1990 Application #90-24P 6 . The plans submitted are not on standard size sheets. The final plans, once approved by Planning & Zoning, will have to be converted so they can be filed with the Town Clerk. This does not necessarily affect the review and approval by IWA/CC for the regulated activities requested on this application. 7 . The application form indicates the total project area is 46 .45 acres, 2.9% is wetlands. There is approximately 114 cubic yards of excavation within the wetlands and the 40 foot buffer and 466 cubic yards of fill within the 40 foot buffer. 8 . There are two areas near the northern end of the Plum Gully Brook where there is no siltation control shown at the toe of the proposed grades near the brook itself. There are also proposed grades along the westerly property line which need siltation control shown at the toe of the slope along the property line. 9 . Erosion and sedimentation control measures should be shown for the proposed riprapped plunge pools to protect the Plum Gulley Brook. 10. The permanent stabilization of the four outlets should be evaluated based on the discharge rates to ensure adequate protection from erosion. It is unclear whether or not the table for plunge pools on sheet L-8 discharge considers discharge rates . The outlet protection should be done based on Connecticut Guidelines for Erosion and Sedimentation Control. Considering that these outlet directly into wetlands they should be dimensioned and detailed clearly on the plans. 11 . There are proposed grades on sheet L-3, easterly of the northern end of Plum Gulley Brook, which. do not show up on the matching section on sheet L-4. 12. The definition of clean fill, as found in section 2.1t in the Regulations, should be included on the plans. The areas near the Plum Gulley Brook should be clearly labeled "clean fill only" . James A. Lombardi Page Three Application #90-24P April 11, 1990 13 . There are no temporary or permanent seeding schedules or seeding types identified on the plans . These should be established in accordance with Connecticut Guidelines for Erosion and Sedimentation Control, and should take into account the steep slopes and soil types . 14. The Schedule of Activities for Construction, item #4 addresses stockpiled topsoil. This note should be modified to include seeding of the stockpiles. The topsoil storage area #1, according to the plans, will be in place for a full year. Topsoil storage area #2, according to the plans, will be in place for over two years. Topsoil storage area #3 is to be in place for- only about four months . Topsoil storage area #2 is to be split with a driveway through the middle. I would recommend that this be consolidated and also moved further away from the road as it may cause visibility problems. 15. Hooded catch basins should be shown for the basins nearest the discharges . A detail for hooded basins should be included on the plans . 16 . An overall phasing plan should be developed to limit the amount of area disturbed at one time. 17 . These comments should be addressed prior to any approval by the Commission.

Lombardi, Chairman, Inland Wetlands Agency/Conservation Commission FROM: John E. McCahill, Zoning/Wetlands Enforcement Officer Y.r �If RE: Application #90-24P, South Windsor High School Please accept this as a follow-up to my letter dated April 12, 1990. Consideration has been given to documents, correspondence, and plans submitted up to this date. COMMENTS: 1 . There are proposed grades along the westerly property line which need siltation control shown at the toe of the slope along the property line. 2. The definition of clean fill, as found in section 2 . 1t of the Regulations, should be included on the plans . In the modified plans they included a definition of clean fill based on "State Construction Criteria" . The areas near the Plum Gulley Brook have been clearly labeled "clean fill only" . 3. I would still recommend that topsoil storage area #2 be consolidated into one area and also relocated further away from Ayers Road. 4. There were concerns expressed by the Commission during the presentation as to whether or not the hooded catch basins, as shown on modified plans, are adequate_ protection to filter out grease, oil, and siltation. These should be evaluated to determine if deeper sumps or perhaps siltation chamber(s) are necessary. 5. Comprehensive dust control measures should be added to the plans. 6• There is still a need to develop an overall phasing plan to limit the amount of area disturbed at time. If this is to be controlled by the "construction manager" perhaps that person, if already determined, should address the Commission. James A. Lombardi Page Two April 26, 1990 Application #90-24P 7 . If a temporary turning radius is going to be utilized near the southerly end of the building, near the existing brook crossing, this should be shown on the plans. If construction vehicles will utilize this area a construction entrance should be provided. 8. If there are plans to tie into proposed sewer lines along Nevers Road, this should be shown on the plans . 9. The plans should identify a temporary seeding schedule and seed type(s) for quick stabilization of disturbed areas. This should be established in accordance with Connecticut Guidelines for Erosion and Sedimentation control. 10. These comments ' should be addressed prior to any approval by the Commission.

The purpose of the structure is to minimize runoff from the project site onto my clients ' property. The runoff situation was created at the time that the Town developed the original school property. According to my clients, the site work included regrading of the track area which caused an increase in runoff in the direction of the Hill property. In an effort to try to correct the runoff, the Hills planted several rows of trees along the length of the property boundary. I recognize that the current proposal will redirect a portion of the previously created runoff away from the Hill property. However, considering that the town is in the process of redeveloping the entire site, the current application process is the appropriate time to adequately rectify the original runoff. If you have any questions, please do not hesitate to contact me. Thank you for your consideration.

DUST CONTROL (DC) z .. z I; 'DEFINITION The control of dust on construction sites and 'roads. 2. PURPOSE To prevent blowing and movement of dust from exposed soil surfaces, and reduce the presence of dust which may cause off-site damage, be a health hazard to humans, wildlife and plantlife, or reduce traffic safety hazard. 3. APPLICABILITY This measure is applicable to areas subject to dust blowing and soil movement where on- and off-site damage is likely to occur if preventive measures are not taken. - 4. PLANNING CONSIDERATIONS Use traffic control to restrict traffic to predetermined routes. Maintain as much natural vegetation as is practicable. Use phasing of construction to reduce the area of land disturbed at any one time. The use-of temporary mulching, permanent mulching, temporary V vegetative cover, permanent vegetative cover, or sodding will reduce" the need for dust control . ' Use mechanical sweepers on paved surfaces - where necessary to prevent dust build up. Stationary sources of - -' C dust, i.e. , rock crushers, should utilize fine water sprays to ' control dust. 5. INSTALLATION REQUIREMENTS a. Spray-On Adhesives G„Wdtkl,e c - ,� So, l Anionic or cationic asphalt emulsion, latex emulsion and resin in water are acceptable. For application rates and dilutions E2S►ti n c. on specific sites, refer to manufacturer's guidelines. - $��.,�. b. Water _ The exposed soil surface should be moistened periodically Adequate water to control dust. P ically with C. Calcium Chloride Shall be either loose dr - _ y granules or flakes fine enough to " —feed through a_.sp-rea_ d„ er_at a rate that will keep surface moist ti but not cause polluon o—"-j ant damage. To reduce potential for environmental degradation, use only when other methods are not practical. ----� d. Stone Cover surface with crushed stone or coarse gravel. In areas adjacent to waterways use chemically stable aggregate. 6. MAINTENANCE When temporary dust control measures are used, repetitive treatment l shall be applied as needed to accomplish control . �- ---�" D. TOPSOILING (TO) C � S" f I. DEFINITION C � The spreading of topsoil of a suitable quality over an area to be stabilized by establishing vegetation. 2. PURPOSE To provide a suitable growth medium for final site stabilization with vegetation. 3. APPLICABILITY a. Where the use of topsoil is determined to be the most effective method of providing a suitable growth medium. b. Where the subsoil or existing soil present the following problems: (1) The texture, pH, or nutrient balance of the available soil cannot be modified by reasonable means to provide an adequate growth medium (,ands, gravels, clays). (2) The soil material is too shallow to provide an adequate root zone and to supply necessary moisture and nutrients for plant growth. ( (3) The soil contains substances potentially toxic to plant growth. p t C. Where high quality- turf is desirable to withstand intensive use or meet aesthetic requirements. . d. Where ornamental plants will be established. e. To be used on slopes that are 2 to 1 (2 horizontally to l vertically) or flatter. 4. PLANNING CONSIDERATIONS Topsoil is the surface layer of they natural soil profile, generally characterized as being darker than the subsoil due to the presence of organic matter. It is the major zone of root development, containing much of the nutrients available to plants, and supplying a large amount of the water used by plants. Topsoil provides an excellent growth medium is high in organic matter content and has a fr1a-b+e-consistency, high water-holding capacity and nutrient content. Vegetative growth is more rapid on sites with at least 4 inches of topsoil , and health and quality of vegetation is better than on sites with little or no topsoil. However, stripping, stockpiling, and reapplying topsoil , or importing topsoil is expensive. The need to topsoil can delay 7-13 seeding or sodding operations, increasing the exposure time of critical areas. Most topsoil contains some weed seeds, and weeds may compete with desirable species. that of preparing a see In site planning, the option of topsoiling should be compared with dbed in subsoil (See measures for Permanent Vegetative Cover [page 6-5], Soddin Vines and Ground Cover 9 [page 6-131, and Trees, Shrubs, with proper seedbed preparationlma)� Limed and fertilized subsoils medium if moisture is not limitingY provide an adequate growth Topsoiling is strongly recommended where ornamental plants or high-maintenance turf will be grown. Topsoiling is a required procedure when establishing vegetation on shall containing potentially toxic materials, and soi ow soils, soils Is with a pH of 4 or below (high acid). If topsoiling is to be done, the following items should be considered: a. Determine whether or not an adequate volume of topsoil exists ' on the site. Topsoil will be spread at a minimum compacted depth of 4 inches. b. —Stockpile topsoil so that it meets specifications and does interfere with work on the site. not C. Allow sufficient time in scheduling for topsoil to be spread and bonded with the subsoil prior to seeding, sodding, or planting. d. Care must Gi be taken when a 1 in to soil to subsoil if the two soi s ave contrastin textures or stron contrastin ensit �•e• ar an opsoi over compacte su soi1 is a particu ar y poor combination, as water creeps along the junction between the soil layers and causes the topsoil to slough. The hardpan must be scarified prior to spreading topsoil to ensure adequate bonding. e. If topsoil and subsoil are not properly bonded, water will not infiltrate the soil profile evenly and it may be difficult to establish vegetation. 5. INSTALLATION REQUIREMENTS a. Materials Site investigations--sh-a4--T- -made to determine if there is sufficient topsoil of good quality to justify stripping. High quality topsoil shall be friable and loamy (loam, sandy loam, silt loam, sandy clay loam, clay loam). Other soil types with high organic content may be found suitable after testing. It shall be free of debris, trash, stumps, rocks, roots, and noxious weeds. It shall give evidence of being able to support healthy vegetation. It shall contain no substance that is i Potentially toxic to plant growth. 7-14 All topsoil shall be tested by a recognized laboratory for the following and shall meet the requirements given: / Organic matter content shall be not less tha n 1.5% by weig t. H ran a shall be 6.0-7.5. If pH is less than 6.0, lime shall be added in accordance with soil test results or in accordance with the recommendations of the vegetative establishment practice being used. Soluble salts shall not exceed 500 ppm. If additional off-site topsoil is needed, it must meet the standards stated above. b. Stripping Stripping shall be confined to the immediate construction area. A 4 to 6 inch stripping depth is common, but depth may vary depending on the particular soil . All perimeter dikes, basins, and other sediment controls shall be in place prior to stripping. C. Stockpiling Topsoil shall be stockpiled in such a manner that natural drainage is not obstructed and no off-site sediment damage shall result. d. Side Slopes Side slopes of the. stockpile shall not exceed 2 to 1 (2 horizontally to 1 vertically). e. Sediment Barrier A sediment barrier shall surround all topsoil stockpiles. f. Temporary Seeding Temporary seeding of stockpiles shall be completed within 15 days of the formation of the stockpile, in accordance with the Temporary Vegetative Cover measure (page 6-1). g. Site Preparation Before topsoiling, establish needed erosion and sediment control measures such as diversions, grade stabilization structures, waterways,—sediment_basins, etc. These measures must be maintained during topsoiling. h. Grading Previously established grades on the areas to be topsoiled shall be maintained according to the approved plan. 7-15 i mig O-P saa� vzn� 1540 SULLIVAN AVENUE SOUTH WINDSOR, CONN. 06074 AREA CODE 203/644-25n -1990 �. _August .91 4 a 0 & G-Industries; Inc 112.Wall Street -- -- - - --- -- - a >P.O:°--Box 907 Torrington, CT 06790-0902. - Attention Brad Gardiner Dear Mr. Gardiner Re:, South Windsor High School Additions and -Renovations At the August 9, 1990 Coordination Meeting you briefly discussed item 3.02, Dust.

Fitts 239 Oak Street South Windsor, CT 06074 Dear Mr. Fitts: Re: Application #90-24P, South Windsor High School As you recall on April 18, 1991 I attended the biweekly coordination meeting and questioned when seeding of the disturbed areas would take place and indicated a concern with future potential dust problems (item #18-5 ) . Mr. Gardiner responded by stating that ADC was not expected back on site for another few weeks, the date was very uncertain. It did not sound as though seeding of the disturbed areas was even being considered. I would like to bring your attention to sheet L-10 of the approved plans . Item #2 of the Erosion and Sediment Control Measures states, "Land disturbance will be kept to a minimum, restabilization will be scheduled immediately after disturbance" . The optimum seeding date, in a general sense, is mid April through mid June. Taking advantage of the optimum growing season can reduce costs and prevent ongoing routine maintenance associated with soil erosion and sediment control . In addition, this project is tentatively scheduled on the May 13, 1991 Inland Wetlands Agency/Conservation Commission agenda for an extension of the permit. It would seem that seeding of the site should be resolved prior to that meeting. I would also recommend that someone familiar with the overall site work be present at the May 13th meeting to answer any questions that may arise from either the Agency or the public. If you have questions, feel free to call me at 644-2511 . Very truly yours, <Y. rmCC" J�ofin E. McCahill, Zoning/Wetlands Enforcement Officer JEM/pmm cc: Brad Gardiner, 0 & G Industries Sylvia M.

McCahill, Zoning/Wetlands Enforcement Officerf/fl DATE: May 1, 1991 RE: Letter dated April 25, 1991 regarding "Land Disturbance. . . " As you requested, Edd Wilcox and I walked the site today. I indicated to Edd during our walk that there were a few areas where - -'-- temporary vegetative cover should be established. This would include: 1) the area southerly of the existing school (along Plum Gully Brook) , 2) the area northerly of the existing Nevers Road exit (where waterlines were installed) and, 3) the entire area northerly of the existing school (where the future addition will be built in the fall) . Establishing temporary vegetation will help reduce maintenance associated with soil erosion and sedimentation control and aid in controlling dust problems . During our walk there were also areas at the southerly end of the school where the silt fence was washed over and catch basins were unprotected. The roadway in that area should also have some cross- slope protection (i.e. , staked haybales) and the plunge pool should be cleaned out. I have attached information from the approved plans and the "Guidelines for Soil Erosion and Sediment Control" to justify the request for temporary vegetative cover.

TEMPORARY VEGETATIVE COVER (TV) 1. DEFINITION Establishment of temporary vegetative cover on soils exposed for periods of up to 12 months. 2. PURPOSE To temporarily stabilize the soil and reduce damage from wind and/or water erosion and sediment deposits until permanent stabilization is accomplished. 3. APPLICABILITY On exposed soils that have the potential for producing sediment and causing on- or off-site damages. 4. INSTALLATION REQUIREMENTS a. Site Preparation (1) Grade as needed and feasible to permit the use of equipment for seedbed preparation, seeding, mulch application, and mulch anchoring. All grading should be done in accordance with the measure for Land Grading (page 7-17). (2) Install needed erosion control measures such as diversions, grade stabilization structures, sediment basins and grassed waterways. b. Seedbed Preparation Apply limestone and fertilizer according to soil test recommendations such as those offered by the University of Connecticut Soil Testing Laboratory. Soil sample mailers are available from the local Cooperative Extension Service office. If soil testing is not feasible on small or variable sites, or where timing is critical , fertilizer may be applied at the rate of 300 pounds per acre or 7.5 pounds per 1,000 square feet of 10-10-10 or equivalent. Apply limestone (equivalent to 50 percent calcium plus magnesium oxide) as follows: Soil Texture Tons/Ac. Lbs/1000 sq. ft.

(2) Where the soil has been compacted by construction opera- tions, loosen soil to a depth of 2 inches before applying fertilizer lime and seed. (3) Apply seed uniformly by hand, cyclone seeder, drill , cultipacker type seeder or hydroseeder (slurry including seed and fertilizer). Hydroseedings, which include mulch, may be left on soil surface. Seeding rates must be increased 10 percent when hydroseeding. d.

PERMANENT VEGETATIVE COVER (PV) 1. DEFINITION Establishment of permanent vegetative cover on exposed soils where perennial vegetation is needed for long term protection. 2. PURPOSE To permanently stabilize the soil , to reduce damages from sediment and runoff and to enhance the environment. 3. APPLICABILITY On exposed soils that have a potential for producing sediment and causing on or off-site damages. 4. PLANNING CONSIDERATIONS Provisions shall be made for surface and subsurface drainage, as needed, and for disposal of runoff without causing erosion. . Facili- ties may include diversions, grade stabilization structures, stream- bank stabilization or waterways. Consider establishing permanent seeding in stages. For example, establish vegetation on cut or fill slopes every 15 feet vertically or 30 feet horizontally. 5. INSTALLATION REQUIREMENTS a. Site Preparation Grade as needed and feasible to permit the use of conventional equipment for seedbed preparation, seeding, mulch application and anchoring, and maintenance. All grading should be done in accordance with the measure for Land Grading (page 7-17). b. Seedbed Preparation (1) Apply limestone and fertilizer according to soil tests such as those offered by the University of Connecticut Soil Testing Laboratory. Soil sample mailers are available from the local Cooperative Extension Service Office. If soil testing is not feasible on small or variable sites, or where timing is critical , fertilizer may be applied at the rate of 300 pounds per acre or 7.5 pounds per 1,000 square feet using 10-10-10 or equivalent. In addition, 300 pounds of 38-0-0 per acre or equivalent of slow release nitrogen may be used for topdressing. Apply ground limestone (equivalent to 50 percent calcium plus magnesium oxide) as follows: Soil Texture Tons/Ac. Lbs/1000 sq. ft. Clay, clay loam and high 4 180 organic soil Sandy loam, loam, silt loam 3 135 Loamy sand, sand 2 90 6-5 a- r Refer to county soil survey report for soil textures at the site. (2) Work lime and fertilizer into the soil as nearly as practical to a depth of 4 inches with a disc, spring tooth harrow or other suitable equipment. The final harrowing or discing operation should be on the general contour. Continue tillage until a reasonably uniform, fine seedbed is prepared. All but clay or silty soils and coarse sands should be rolled to firm the seedbed wherever feasible. (3) Remove from the surface all stones two inches or larger in any dimension. Remove all other debris, such as wire, cable, tree roots, pieces of concrete, clods, lumps or other unsuitable material. (4) Inspect seedbed just before seeding. If traffic has left the soil compacted, the area must be retilled and firmed as above. C. Seeding Dates Spring seedings usually give the best results. Spring seedings of all seed mixes with legumes is recommended, however late summer seedings prior to September l can be made. When crown vetch is seeded in late summer at least 35 percent of the seed should be hard seed (unscarified). The recommended seeding dates are: April 1 through June 1 * August 15 through September 1 With the exception of crown vetch, the final seeding date may be extended 15 days in the coastal towns of New London, Middlesex, New Haven and Fairfield counties. d. Seeding (1) Select a mixture from Figures 6-2 or 6-3 or use mixture recommended by the Soil Conservation Service. Inoculate all legume seed with the correct type and amount of inoculant. (2) Apply seed uniformly by hand, cyclone seeder, drill , cultipacker type seeder or hydroseeder (slurry including seed and fertilizer). Normal seeding depth is from 1/4 to 1/2 inch. Hydroseedings which are mulched may be left on soil surface. (3) Where feasible, except where either a cultipacker type seeder or hydroseeder is used, the seedbed should be firmed following seeding operations with a roller, or light drag. Seeding operations should be on the contour. 6-6 �l '1OwN 8 4 c �� • ° w� 1540 SULLIVAN AVENUE . SOUTH WINDSOR, CONN. �dsoe•coN� 06074 AREA CODE 203/644-2511 Howard E.

Complaint—(Please be clear, but brief) We are concerned about damage to our house foundation, plaster walls , inground pool and to our well.The extreme ground vibrations during the earth compaction process for the installation of t'ie high school field track, which abutts our property, is .the cause of our concern. Since this work began we have had a drop in our well level on 3 separate occasions causing us to be without water. Additionally our well water now contains a fine grit that is evident by the stains to our plumbing fixtures. Route To Final Action Date ;`ji - r✓ 1540 SULLIVAN AVENUE SOUTH WINDSOR.
