MOELLER SOUTHBURY, CONNECTICUT 06488 PHONE: (203) 264-6977 PEDOLOGiST (SOIL SCIENTIST) AND CONSULTANT - 'October 29, 1982 ON-SITE SOILS INVESTIGATION OF PROPERTY FOR PHILLIP IRELAND ON ELLINGTON ROAD I have conducted an on-site soils investigation of the property located on Ellington Road in South Windsor, Connecticut. The principal purpose of this soils investigation was to locate and identify the wetland soils and produce a high -inten- sity soil survey. The soils were mapped on the 1980- aerial photos through intensive field investigation and aerial photo interpretation. The general procedure was to use standard soil survey techniques but in greater detail than in the original Hartford County Soil Survey. In this soils investigation and soils report, the classification of the soils, soil textures, descriptive terms, and drainage classi- fications follow the guidelines and criteria of the National Cooperative Soil Survey. SUMMARY OF SOILS ON THE PROPERTY----- The property-consists basically of soils formed from till deposits on a nearly level to .gently sloping landscape. The upland soils range from moderately well drained to well drained soils. The wetlands are nearly level low areas in which the' surface of the soil is near or at the level of the water table. While the basic parent material of the soils consists of fine sandy loam and sand loam till., there are numerous inclusions of coaA6 sand and sand. and gravel deposits or soils formed over sand and gravel. In places there is a mixture of both materials. Therefore, the named soils on the property .are not within the normal range of characteristics for numerous areas within the mapping units. They are however properly mapped as far as drainage classification and basic textural family is concerned. Some of the soils also have a silt loam surface. 'The soils towards the southern end of the property were higher in silt loam textures than the soils at the northern end or northwestern end. The wetland soils range from poorly drained to very poorly drained. The variation is due to the elevation above the water table and to some influence of capillary action of'the soil material. At the northwestern end- the soils vary in elevation. The shallow muck is nearly level. Water flows very slowly to the north- west and eventually into a stream which cuts across a corner of the property. The Walpole soils are wet due primarily to capillary action and are mineral soils with a firm base. In places, they are underlain by till. The Walpole soils also have some slope .and an undulating topography with small hills and depressions. The Saco soils have inclusions of stony soils and there is a very poorly defined intermittent drainageway or stream flowing to the stream in the northwest corner of the property. There is also a slight slope in places in this mapping unit. The Scarboro soils in the same northwest end of the property have a very slight slope in places but generally form a gradual transition from the shallow muck to the moderately well drained soils. 159 HULLS HILL ROAD I I g SOUTHBURY, CONNECTICUT 06488 PHONE: (203) 264.6977 ON-SITE SOILS INVESTIGATION I SOIL MAPPING I "WETLAND" IDENTIFICATION I SOILS INFORMATION AND CONSULTATION I I SOILS INVESTIGATION OF IRELAND PROPERTY, SOUTH WINDSOR---2 HTM 10/29/82 The other wetland at the southeastern end of the property is nearly level with some transitional poorly drained Walpole soils. Part of the Scarboro soils and the Saco soils form a transition between the muck soils and the moderately well drained upland soils. The major portion of this wetland is nearly level except for the Walpole soils which are higher and have an undulating topography. Again, the Walpole soils are poorly drained due to capillary action on the water table below. The Saco soils also form a transition to the upland soils on and off the property at the southeastern end. Part of this area has drainage ditches which appears to have been done for agricultural purposes. UPLAND SOILS MAPPED----- LoA Ludlow fine sandy loam, 0 to 3 percent slopes. The Ludlow series is a member -of the coarse-loamy, mixed, mesic family of Typic Fragiochrepts. "The Ludlow series consists of deep, moderately well drained soils on uplands. They formed in glacial till.. Typically these soils have a dark brown silt loam surface layer 8 inches thick. The subsoil -from 8 to 20 inches is reddish brown silt loam and from 20 to 26 inches is mottled dark reddish brown silt loam. The mottled substratum from 26 to 48 inches is dark reddish brown gravelly loam." On the property this soil has inclusions of loamy sand and sandy loam in the substratum. The surface also consists of fine sandy loam. In thE'area of the. power line right-of-way, -the soils appear to have been disturbed in the clearing operation. The surface is stony in places. WeA Wapping silt loam, 0 to 3 percent slopes_.. . The Wapping series consists of 20 to 30 inches of silt loam over fine sandy loam and sandy loam till. The till may be friable or compact. The soil is moderately well drained. On the property this soil consists of 15 to 2S inches of silt loam over fine sandy loam grading into sandy loam till. There are numerous inclusions of sand and gravel in places and coarse sand in the underlying substratum. The soil profile is stony in the soil profile in most areas on the property. This soil is similar to the Ludlow soils described above, except the surface is silty. In most areas this soil has a friable substratum. In places near the wetland soils there are inclusions of silt and fine sand lenses in the subsoil and substratum. WkA - Wethersfield fine sandy loam, 0 to 3 percent slopes.. The Wethersfield series is a member of.the coarse-loamy, mixed, mesic family of Typic Fragiochrepts. "The Wethersfield series consists of deep,. well drained soils on uplands. They formed in glacial till. Typically these are. reddish colored well drained soils with a slowly to very slowly permeable fragipan at about 2 feet. The soils have developed in till derived from reddish colored rocks. The surface and subsoil layers are friable to very friable loam or silt Ioams with varying amounts of rock fragments. The fragipan restricts internal drainage. A temporary perched water table may be present above the pan in wet seasons and after heavy. rains in summer.. . ." On the property these soils differ from the above in several characteristics. The fragipan or hard compact till is generally at 35 to 40 inches or .may be below 40 inches. The surface is coarse textured consisting of fine sandy loam to sandy loam and grading to loamy sand in the subsoil to the substratum. The soil profile is also stony in places. Inclusions of sand are also present. Overall the upper 35 to more than 40 inches are moderately permeable on the property. SOILS INVESTIGATION OF IRELAND PROPERTY, SOUTH WINDSOR---3 HTM 10/29/82 WkB Wethersfield fine sandy loam, 3 to 8 percent slopes. These soils are as classifidd and described above, except the slopes are steeper. WETLAND SOILS MAPPED----- PmA Mucks and Peats, shallow, 0 to 1 percent slopes_ - On the property these soils consist of 16 to 40 inches of well decomposed organic material over sand or sand and gravel. Just under the muck there is a thin layer of silt loam that is approximately 5 to 10 inches thick. At the northwest end of the property this mapping unit is- stony in the underlying mineral soil material in places. At the southeast end of the property the mucks may be deeper than 40 inches at or off the property. These areas were not checked in detail because most activity will not be in this wetland on the east or southeast end. SbA Saco silt loam, 0 to 2 percent slopes. The Saco series is a member of the coarse silty, mixed, nonacid, mesic family of Fluvaquentic Humaquepts. "This is a very poorly drained silty soil on floodplai_ns. It has dark-colored surface horizons over mottled gray subsoils and substratum. The ground water table is at or near the surface from late fall through early spring. This soil is frequently flooded." On the property this soil -generally consists of lenses of silt loam and sandy loam over sand at 30 to 40 inches. At the northwest end of the property, there are stony areas and there is a poorly defined intermittent stream flowing through. In places this soil. also has a thin muck surface less than 15 inches thick. These soils on both ends of the property are subject. more to ponding due to the level surfaces rather than to any streams overflowing their banks. SeA Scarboro silt loam, 0 to 2 percent slopes. The Scarboro series' is a member of the sandy, mixed, mesic family of Histic Humaquepts. "These are very poorly drained, coarse textured,, soils. . . . ' The surface soils are dark colored and high in organic matter. The subsoils are grayish colored and sandy. Scarboro soils occupy low-lying, flat or depressed areas. The ground water table is normally at or near the surface from late fall through late spring, but -may drop below 3 feet in the summer months. These soils drain readily where suitable outlets are available and they are .rapid-ly permeable when the water table is lowered." On the property these soils have a thin layer. of silt loam at the surface or just below a thin muck surface. The upper portion of the soil profile including any muck and silts is less than 20 inches thick over a coarse sand. Lenses of coarse silt or fine- sand may be present in the substratum in places. WcA Walpole loam, 0 to 3 percent slopes. The Walpole series is a member of the sandy, mixed, mesic family of Aeric Haplaquepts. "This is somewhat poorly to poorly drained soil -over sand and gravel. It has relatively thin dark colored surface horizons over mottled subsoil. Surface and subsoil textures range from fine sandy loam to sandy loam. Depth' to sand' and gravel ranges from 18 to 30 inches. A seasonal water table is near the surface from 0 SOILS INVESTIGATION OF IRELAND PROPERTY, SOUTH WINDSOR---4 HTM 10/29/82 late fall through early spring. During dry parts of the year the water table may drop to 6 -feet or deeper. . . ." On the property this soil has a finer surface texture. It also has inclusions of stony sandy loam till in areas. In places the surface is also stony. It is' higher in elevation than the other wetland soils and is wet due to the capillary action of the soil pulling up the water table below. It does not contribute significantly to the flood storage capacity of the wetlands. Within the mapping units are small inclusions of moderately well drained soils. These soils also have anirregular topograVhy in places with small hills of moderately well drained soils and depressions of poorly drained soils.

MOELLER SOUTHBURY, CONNECTICUT 06488 PEDOLOOIST (SOIL SCIENTIST) AND CONSULTANT PHONE: (203) 264-6977 December 6, 1982 SUPPLEMENTARY SOILSIREPORT ON PROPERTY FOR PHILLIP IRELAND ON ELLINGTON ROAD The first soils report is entitled ON-SITE SOILS INVESTIGATION OF PROPERTY FOR PHILLIP IRELAND ON ELLINGTON ROAD, October 29, 1982. The first soils report describes in detail all soils mapped on the property and the general characteristics of the wetland soils on the property. The principal purpose of this soils report is to assess the impact of the property development to the wetlands on the property and downstream adjacent to the property. . The concerns are the water tables and surface water movements. The entire property is nearly level to gently sloping. The wetlands occupy the level depressions which essentially exposes the water table. The Wnderlying material consists of till and outwash deposits. Some of the material is slowly permeable. and, t other material is permeable throughout. Due to the nearly level slopes and the topo- graphy, the water from direct precipitation and runoff from adjoining properties is trapped and moves very slowly. The water moves downward to the water table either directly through the soil or as runoff from the soils at slightly higher elevations. Any excess surface water than moves very slowly through the wetlands downstream. At the northwest corner of the property. the water reaches a well defined stream channel which flows to another wetland north of the property. Part of this wetland is on:the east end of the property which is known 'as Parcel IIA":and consists of a shallow muck soil. The movement of ground water was not within the scope of this investigation. It is assumed that there is some ground water movement but it does not change the soil interpretations of basic wetland functions. The surface water basically flows from the south to the north -through the wetlands on the property. Due to. the nearly level surfaces, the restricted outlets, and the dense vegetation,' the wetlands function as water detention basins. They slow the runoff from the up- lands and pond the water during heavy rainfall. However, only the very poorly drained soils are subject to normal ponding or flooding. The poorly drained soils are at. a slightly higher elevation and are saturated due primarily to capillary action. The Walpole soils are poorly drained. In the proposed development the property will be developed in two stages. Parcel IIBII will be completed first. It is proposed to put a road through both parcels. The road goes southeast through as much upland as possible and then turns east into a wetland. The reason for this turn is to avoid a future intersection with the five corners. Homesites will be built along both sides of the road. In planning the property, the wetlands. were avoided as much as possible for the houses themselves and -" immediate yard area. The size of the lots were determined on the basis of'minimum impact to the wetlands for necessary filling. 159 HULLS HILL ROAD I I SOUTHBURY, CONNECTICUT 06488 PHONE: (203) 264.6977 ON SITE SOILS INVESTIGATION SOIL MAPPING I "WETLAND" IDENTIFICATION SOILS INFORMATION,AND CONSULTATION c3 SUPPLEMENTARY REPORT OF PROPERTY ON •ELLINGTON ROAD----2 HTM 12/6/82 Because sanitary sewers and water is available, there is no need for septic systems which are greatly dependant on the nature of the soils. Thus, -there is also no need to fill in large areas or use large areas for septic systems and reserve areas. Only the house itself and some yard area is all that is required for the homesite. With the construction of homes, driveways, and roads, there will be increase of runoff due to impervious surfaces. Lawns also have a higher runoff rate than forest land. The nearly level to gently sloping surfaces reduces the erosion hazard consi- derably. The distance to the wetlands is also relatively short. Thus, the water cannot accumulate high volumns along with high velocity before being dissipated by the wetlands. The impervious surfaces however will be less than 20 percent and .cannot affect the water table of either the wetlands or the uplands to any significant extent. The water table is maintained by a much larger watershed than the property itself.-, Water can still percolate down through more than 80 percent of the soils. During a storm the runoff will cause slightly higher water levels in the"wetlands due to the impervious surfaces. However, the amount of increase is insignificant to the normal fluctuations of the water table in the wetlands. Any increase will also be for very brief periods and thus, will not affect the vegetation nor basic soil moisture regime of the wetlands. Excess water will still be free to flow off the property as it presently does. Drainage has been provided to maintain the free flow of water off the property. The only change is a detention basin- to meter. the water into the stream that flows off the property. In the .existing corfd tion there is 'a poorly defined stream channel in the area of the proposed drain and detention basin. However the basic direction of surface water flow is maintained and the water levels will not be changed. Some wetland soils will. have to be filled for. either,a road crossing, homesite, or yard area. Most filling will take place on the Walpole soils which- are poorly drained and slightly;higher in elevation. 'These soils do not._contribute to the water storage capacity of the wetlands for most ,storms. . Any. displacement of water storage Capacity for a severe storm would be =spread over a large remaining wetland area. Any increase of water level due to the filling would not even be_measureable'. The water. storage capacity of the wetlands has not been significantly changed. The detention pond has also minimized the loss. The detention pond reduces the peak flow into the stream off the property and also helps to prevent erosion which presently occurs in the. Saco soils- near the detention basin. Overall the subdivision has left most of the large areas of very poorly drained soils intact. The direction of water movement has not changed. Due to the soils, topography, and slopes of the land, :the amount of increased runoff s minimal and will not change the moisture regime of the wetlands nor affect the vegetation.

A development is proposed on a 39.4 acre wooded parcel of .land. 2. A detailed on-site soils investigation has been conducted on this property by Henry T. Moeller, soil scientist. 3. The property is divided into parcel A and parcel B, separated by a 300 ft wide C L & P right of way. EVALUATION 1. The site plan as submitted for this area shows a proposed retention basin for storm water runoff from parcel "B". However, there is. not a retention basin planned for the runoff from parcel "A". Plans show the runoff being discharged directly into the adjacent wetland soils. Sediment from . construction activities, road sand and salt will be discharged into these wetland areas. The construction of a retention basin on parcel "A" is needed to collect these materials during construction and to store runoff waters during and after construction. 2. There is to be fill placed in the wetland soils for road construction and lot development. The site plan states that the total amount is 7,210 cubic yards and shows fill being placed precisely where- the houses are planned. However, there exists a question here, as to whether it is realistic to construct a house and walk 10 - 20 feet out the back door into a wetland. Therefore, any backyard is almost non-existent. Homeowners may want to "develop" their backyards by placing fill_ there in the future. Also, there will be activity in the wetlands just to fill and excavate for the houses. The site plan does -not appear to realistically show the activity and fill placement in the wetlands. Therefore, the potential to damage and/or fill in a much larger area of wetland exists. This combined with the absence of a retention basin on parcel "A" could have a detrimental effect on this wetland, . 3. There is an absence of an erosion and sediment control plan for this site. Proper temporary and permanent erosion and sediment controls should be shown on the site plan. The Connecticut Erosion and Sediment Control Handbook should be used to develop this plan.

It is the opinion.of the Hartford Soil and Water Conservation District that construction in specified areas of parcels A & B would be a detriment to the existing wetland. The Hartford County Conservation District therefore, recommends a decrease in the proposed number of dwellings to be built on these parcels. The present plan does not adequately provide for a soil. erosion and sedimentation plan to, reduce damage to the environment. Construction as proposed would: be a potential hazard to. the existing ecology of the wetland increase soil erosion and sedimentation into the wetland increase storm water runoff The District suggests that lots 1, 4, 8 & 9 be eliminated in parcel B as 50 percent or more of these lots are located in wetlands. Recommendations for Parcel.. A include combining the following lots into one dwelling instead of two for: lots 11 & 12; 13 & 14; 15 & 16; 19 & 20; 26 & 27; 28 & 29: It is also suggested that a retention basin be constructed on parcel A. These corrective procedures would allow for a decrease: in the encroachment into the wetland amount of fill needed erosion and sedimentation into wetland damage to wildlife habitat - property owners potential crater problems If there are any questions, please feel free to contact our office.

Several modifications to the site plan were discussed and they have been incorporated into a revised plan dated January 12, 1982. Some modifications were to decrease activity in the wetland soils on the site. Specifically they addressed paragraph #2 under evaluation of the December 28th report. The road has been relocated and several lot sizes and home locations have been -adjusted. Also, several lots have been eliminated. However, there is still planned construction on lots 6, 7 and 8 all of which are in wetland soils. The stormwater from half of parcel "A" is now planned to be routed into the retention area on parcel "B". However, the runoff from the other half of parcel "A." is still being discharged into the wetland soil on lot 14. Those comments in our December 28th report regarding erosion and sediment controls should still be addressed. This would include paragraphs 1, 3, 4 and 5. Paragraph 2 concerns have been answered and the planned modifications appear to realistically provide for a yard area around the homes. In summary, there still is some fill activity in wetlands and absence of an erosion and sediment control plan. If further assistance is needed, please call.
