CME Associates, Inc. was commissioned to analyze portions of two watersheds, Podunk River and Avery Brook, for the impacts that would occur due to the replacement of the undersized culvert. The analysis was undertaken with the recognition that the replacement of the undersized culvert may worsen flood conditions downstream. Some homes downstream already experience periodic basement flooding. The study also addresses the issue of whether or not there is a split in the flow of the Podunk River tributary about 900 feet downstream of Miller Road that would cause part of the flow to be directed into the Avery Brook watershed. Also addressed is the impact that such a split in flow would have on Avery Brook down to Beelzebub Road. CUE examined maps and aerial photographs of the area of the split from a variety of sources going back about 50 years. Based on this examination, field survey and hydrologic and hydraulic computations, it appears that normal flows on this tributary are entirely directed toward Podunk River. The evidence suggests strongly that this drainage pattern has not been altered in the recent past. The study focusses on conditions caused by a storm having a probability of occurrence of two percent in any year. In engineering parlance, this storm is called a 50-year storm because, on average, a storm of this intensity should occur every 50 years. The calculations assume fully developed, residential conditions in both watersheds. Any culvert replacements can be expected to serve for a number of decades before their replacement and, as such,will need to be adequately sized for the rapid development that is occurring in the study area. 1 The drainage area of Podunk River and its tributary, from their headwaters down to Abbe Road, contains three small dams and crosses streets in five locations and encompasses about 755 acres. The drainage area of Avery Brook,from its headwater just above Ellington Road down to Beelzebub Road contains two small dams, a driveway crossing, and two road crossings. The drainage area is about 106 acres. The existing drainage structures in both watersheds were analyzed for adequacy in a 50-year storm. From this analysis it can be concluded: • Culverts at Ellington Road,Beelzebub Road,Foster Street,and the three crossings of Miller Road are undersized and warrant replacement. Flood waters will overtop the road in all of these locations. • The culvert at Abbe Road is adequately sized. • All of the dams in the study area would be overtopped by the 50-year storm. An analysis of the ability of the dams to withstand the design storm is beyond the scope of this study and was not performed. • A split in flow of the Podunk River tributary just south of Miller Road could happen if certain conditions change over time. Occurrences such as siltation of the channel,vegetation growth,or partial blockage of the channel caused by a fallen tree or ice could cause a portion of the flow to be diverted into the Avery Brook watershed. • A potential diversion should be taken into account in analyzing potential designs. To be conservative,the Podunk River system should be analyzed assuming no diversion and Avery Brook should have a portion of the flow at the split included in its watershed. A number of alternatives for upgrading the existing culverts were examined. These alternatives can be grouped into the following categories: • Alternatives to examine the impacts of upgrading the culvert at Miller Road near Ellington Road only, assuming no split in flow. 2 • Alternatives for replacing all the undersized culverts in the Podunk River system in order to meet design criteria, assuming no split in flow. • Scenarios for replacing undersized culverts in both watersheds, assuming a split in flow. As a result of the alternative analysis,the following actions are recommended: Podunk River and Tributary: 1. Raise the grade of Abbe Road to a minimum elevation of 230.4 in the area of the existing culvert. The existing 6' x 3' box culvert is adequate if the grade of Abbe Road is raised as recommended. It appears that the street can be raised in this area without impact on adjacent property. Estimated cost: $15,000. 2. Replace the two 36" pipes on Miller Road just east of Abbe Road with a 8' x 3' box culvert,or equivalent,and raise the grade of Miller Road in this area to a minimum elevation of 256.4. Estimated cost: $110,000. 3. Replace the two 36" pipes at Foster Street with a 10' x 3' box culvert, or equivalent. Estimated cost: $120,000. 4. Replace the two 24" pipes at Miller Road just east of Foster Street with a 6' x 3' box culvert, or equivalent. Estimated cost: $80,000. 5. Replace the 24" pipe at Miller Road just west of Ellington Road with two 48" reinforced concrete pipes, or equivalent. Estimated cost: $30,000. Avery Brook: 1. Replace the 15" pipe at Ellington Road with a 4' x T box culvert, or equivalent. Estimated cost: $100,000. 2. Replace the 24" pipe at the driveway just downstream from Ellington Road with a 4' x 2' box culvert, or equivalent. Estimated cost: $60,000. 3. Replace the 30"/36" pipe at Beelzebub Road with a 10' x 3' box culvert, or equivalent. Estimated cost: $460,000. 3 PROBLEM STATEMENT The Town of South Windsor has identified the culvert under Miller Road near the intersection with Ellington Road as being undersized and in need of upgrading for the quantity of stormwater reaching it. The chief concern about doing this is the potential change in downstream flows and impacts on associated downstream structures. This situation is further complicated by the characteristics of the watershed downstream of Miller Road. A wetland area has been identified where a split in the watershed for the Avery Brook and Podunk River may occur. Figure 1 shows the study area and identifies the points used in the analysis. This study addresses the issue of the potential split in flow at this location and presents recommendations for improving culverts in the study area. SOURCES OF INFORMATION The following studies were reviewed for use in comparison with this study being performed on the watersheds of the Avery Brook and Podunk River. • A stud performed b Purcell Associates which was completed in the earl 1970's. YP Y p Y Due to the significant changes that have occurred since this study was completed, it was only useful to compare with information used in the current study. • The Flood insurance studies were also only useful to compare with information used in the current study. • A more recent study by Luchs Associates which looked at the affect of a new development on the crossing at Miller Road near Ellington Road was reviewed. Topographic mapping with 2'contours at 1"=100' scale was provided by the Town of South Windsor for the entire watershed. This mapping is based on aerial photogrammetry dated 1986. The Town also provided MDC mapping which is based on aerial photogrammetry dated 1970. Recent aerial photographs and an old(date unknown) aerial photograph were also examined for evidence of a change in the course of the brook in the area of the"split'. 4 z '`��' ����• y"r��hx�s'"'b'r ;�n �cz�+���Yx ",°` 3 .r ' ✓'^°Y z� r�^'�atz z z r�r zM' x z z^"?a >r `�rr z- " t MR, " w z F�z"zz ,r /a c^.a zt� zr �z zz,.2 �'� �Y z� .�" 1' • Y � z � z r. z xY '�,gz '�°°""' Z" zr a+ ✓' an r,Rz s r asp z# z✓4 J ^" ,r z, f,"zn" n�9z" RN 84' PON x "�m�yzr ad W z" + " ,tGziz ." p a,/' .✓''?" ^d i r,Xw r�wr� n1l H,2 � � ^{.'�✓' ` II, ,CX ,x-i4 4 `�'"��,�G 'C� "�"Y�L fi,2,a� �,u, 4U ��I� .v�M",Zr._S..y,�i�• f a��1�' f✓" a� Y�1�� Y@SaZm^.�'+cGaao�"' .,yy�ixdrrF «;,, ."S�y,7rn$�.a+r' + �. `�",�!,'—�"' ,z. y x R ".1� z zry+ r izrz % b !"., �.,�,�lr�,��f* �"'wa r a. �+r',� �,tivti�Cz�,✓,X y,c., f �aa�l�y rrt ,,zswt.�.wtA�^rr����,of r 4.QZ,'7�+ X ��XX J' /44"LiLY�L'b���$7>"rFw�.^ �n yb"X.� +� z'k.,^�'X/,✓ iJ.�j�kb"d�nn���Y S�,�k�``' f ,^�'�z�k� � �� fit.✓.�� ,P f'���'N.•, z ddzh v2 '� ?�,�', a?r kY �r"� xz,n sv � rvu"v��n�zxX ,,�� z t a+�S izY7 b,rx+r +a s� � �r k �""���,�����m�' �.• ,� : x°,�r � �,��.�".�� � � w'� sa�b �F i z zia;.""F✓'�r � � � e"z x� roe.. �'� "� •g'— H? x z zrx„�� `y"o dwd r"z ,tza,'z w�X�z rc ��7`/z F� �� z � 8�r�� z"w �a� ,r-,...z �'ky'2 -',tk z"�z�' �z�"°nzi�� rS� ✓' �ji �i 4 �2� r� X� rsw e;�� �KX".+ f� ra,�gi° "f` r7vL dti..a',T'= " f !"z fiz ?{gzzby, zxz .,f EGz, Y • �^� ,' Y�f^,+ +', z? �za S z',' �!' ro a a ✓a r #+ `�+fig�� P ,3 °�zx �: rcz HX , ,z ,'z�y'z yy'Syt i� t Z, 1 �'� c+sm' """"z,di ,b. ,�✓F zz � 't ;/`; fXrcz"2z�r.

This is the area identified by the Town as where a split in the Avery Brook and Poduck River watersheds may occur. The areas identified on the map were all surveyed to provide input data for the hydraulic model. In addition to the survey information gathered,information was provided by the USDA Natural Resources Conservation Service on the flood elevations for Avery Brook Flood Retention Dam Site 1. PODUNK RIVER AND TRIBUTARY The area and structures studied for the Podunk River include those structures on the map, as well as the pond and associated structures located downstream of the Miller Road crossing between Foster Street and Abbe Road. This pond has a spillway structure and a bridge that require modeling to provide accurate information on the hydraulics of the river. There is also a pond and structure upstream of the pond located near the Miller Road crossing between Foster Street and Abbe Road. This structure was also analyzed to provide the appropriate input for the hydraulic model. Based on an inspection of the site,the water from the Miller Road crossing near Ellington Road is directed toward the Podunk River watershed. WATERSHED Spur Statements have been made to Town Staff by residents that the Town adjusted the flow patterns in the area of the"split"in the early 1970's. There were no significant rainfall events between the initiation of the study and completion of the hydraulic modeling. Therefore, other historical information, along with more detailed field survey, assisted in assessing the amount of watershed split that occurs. 6 KIM ng Mill ama INN` gg S - ,�` g i � �m, 54 S y(�a 'aa'. ���f ivm- MN 711 5 f MT,- ON Me a U S S S Y ..

Mr. Iazetta provided insight into the problems that have recently been experienced in the watershed and identified areas of special concern based on his experience and complaints received from residents. He also provided CME Associates, Inc. with copies of the Town's 100-scale topographic mapping of the watershed along with recent subdivision plans and drainage calculations recently performed for selected projects in the study area. CME engineers walked the two brooks and the tributary to the Podunk River paying particular attention to the area identified by Town staff as the break between the Avery Brook and Podunk River watersheds (Point B) as well as natural and manmade features not identified in the Town's request for proposals. Mr.Iazetta indicated that the tributary to Podunk River may have changed course a number of years ago, having formerly flowed to Avery Brook. A field investigation revealed no obvious signs of a diversion of this stream. The area around Point B is a broad flat area however, and it appears that there may be some potential for high flows to be directed partially toward Avery Brook. Field survey was performed around each culvert crossing, dam,and bridge identified in the Town's request for proposals and all additional structures found in the field. This provided accurate data for the hydraulic modeling of the streams. Y g All elevations are based on the 1988 North American Vertical Datum(NAVD 88). Cross sections were surveyed using GPS and standard electronic equipment. Hydrologic calculations were performed for the watersheds and sub-watersheds using the methods of the Soil Conservation Service's Technical Release No. 55. HydroCAD, a stormwater modeling program for the personal computer,was used to perform the hydrologic calculations. Information on land use was derived from the Town's 1997 Zoning Map. Soils 8 information for use in the hydrologic model was obtained from the Soil Survey of Hartford County, Connecticut. Topographic data were derived from the USGS Manchester Quadrangle,the Town's 100-scale mapping and field survey. The calculations assume fully developed,residential conditions in both watersheds. Lot sizes were assumed to average one acre throughout. The 50-year storm was chosen as the basis of design based on the Town's design criteria for watersheds of 200 to 1,000 acres in size. For validation purposes, the flows calculated for the Podunk River were compared to the flows used in the Flood Insurance Study. As expected,the flows exceed those used in the Flood Insurance Study by about twenty percent. This can be mostly attributed to the assumption of fully developed conditions in this study. The 50-year flow calculated at Point A on the tributary to Podunk River compared favorably to that used by Luchs Associates in a recent study of the effects of a proposed subdivision on Niederwerfer Road. The Luchs flow rate was adopted for use in this study. The hydrologic calculations were based on the watershed characteristics shown below: Podunk River Time of Pond Drainage Area Concentration Curve Factor (Sq. Miles) (Hr.) Number (%) Point A 0.34 1.25 59 5.0 Point D 0.29 1.15 63 1.5 Point F 1.12 2.62 61 5.0 Avery Brook Point H 0.06 0.43 64 5.0 Point K 0.17 0.84 67 2.8 9 The HydroCAD program was then used to model the effects of storage at each street cross culvert, bridge, and dam in the study area. In effect, these hydraulic structures act as detention ponds. As expected,these hydraulic structures had a significant impact on flows conveyed downstream due to very substantial detention of flood flows behind roadway embankments and dams. The calculated flows were input into the U.S. Army Corps of Engineers Hydrologic Engineering Center's River Analysis System software (HEC-RAS) for personal computer using the Windows 95 operating system. The software computes one-dimensional, steady flow,water surface profiles. It is intended for calculating water surface profiles for steady, gradually varied flow and is capable of modeling subcritical, supercritical,and mixed flow regime water surface profiles. HEC-RAS can handle a full network of channels. The effects of various obstructions such as bridges,culverts,weirs, and other structures in the flood plain are taken into account. The current release of the program does not adequately account for storage,however. Therefore, HydroCAD was used to account for storage and determine the flows input to the HEC-RAS model. In addition,the results of the HEC-RAS runs are used to make sure that the assumed tailwater elevations used in the detention pond calculations were reasonable. Data required includes flows, geometric data accurately describing the structures, culverts, and topography of the flood plain and roughness coefficients (Manning's' ). The geometric data was provided for this study primarily through field survey of both cross sections and structures. Where additional topographic data was needed it was taken from the Town's 100-scale topographic mapping. Estimates of roughness coefficients were made primarily based on personal observation supplemented by viewing USGS orthophotoquads. 10 The first model run for each brook was based on existing geometric conditions. Subsequent runs were performed on the Podunk River and its tributary and Avery Brook to simulate the effects of replacing various culverts. The iterative process of deriving a workable solution for both watersheds involved making about 50 model runs in HEC-RAS and fifteen model runs in HydroCAD. . A control elevation was established at each street crossing,bridge,and dam in the study area. This control elevation was generally set to be one foot below the elevation that flooding of the road or dwellings would begin to occur,whichever is lower. The goal of the modeling was to find the smallest series of culverts in each watershed that would limit the elevation of the 50-year flood to the control elevations. The possibility of altering(raising)the grade of the street at each culvert crossing was also considered as a way of limiting the number and size of culverts to be replaced. Dams in both watersheds would overtop under design conditions and analysis of dam stability is not part of this study. Special attention was given to analyzing the results of the calculations in the area of Point B. The modeling indicates that the 50-year flood elevation in this area is just below the elevation at which some diversion of flow toward Avery brook would occur. Hydraulic and hydrologic models are not sufficiently accurate to conclude that such a diversion would not occur,however, and future siltation of the stream channel,vegetation growth or partial blockage caused by fallen trees or ice, could change the course of the stream temporarily or permanently. Therefore,this study took a conservation approach. The computations in the Podunk River watershed assume that no diversion of waters to Avery Brook occur. The calculations in the Avery Brook watershed assume that 25 percent of the flow from the Poduck river tributary at Point B is diverted to Avery Brook. For comparison purposes, data is also presented for existing conditions assuming no diversion. 11 RESULTS Selected results of the HEC-RAS modeling are presented in Tables 1 through 7. Each table presents the design flows, control elevations, culvert sizes and types and computed flood elevations for one of seven trial runs. Two of the trials are for existing conditions(with and without split) and the others, designated 1 through 4 and A, are for various culvert replacement strategies. The culvert replacements shown in Trials 4 and A for the Podunk River and Avery Brook, respectively, are those recommended. It should be noted that there are any number of workable alternatives to the culvert types and sizes shown. Determination of the locations of underground utilities that may affect the design of the culvert replacements was beyond the scope of the study. Detailed design of each project should consider hydraulically equivalent designs that may be more suitable. Calculations,plotted cross sections, and flood profiles are presented in a separate volume. RECOMMENDATIONS The following recommendations should be implemented in each watershed,beginning at the downstream end of the watershed and proceeding upstream. Careful consideration should be given before implementing projects out of that sequence due to the likelihood of increasing flood elevations downstream. The costs presented below are rough estimates for design and construction. A summary of the recommendations is shown in Table 8. MILLER ROAD (POINT A) The existing 24" reinforced concrete pipe (RCP) at Point A is undersized. It should be replaced with two 48" RCP's or equivalent. Even with the improvements recommended in this study,the homeowner at 590 Miller Road will continue to have a problem with the pipe discharging to the brook from his foundation/ roof drains. The homeowner should give consideration to previous recommendations of the Town Engineer to alleviate his problem. Estimated cost: $30,000. 12 Table 1 TRIAL: EXISTING CONDITIONS; NO SPLIT DESIRED MIN. MIN. OTHER DESIGN MAX. 50-YR. 50-YR. COMPUTED ROAD STRUCT.

It has partially collapsed under the road. The existing 36" RCP is in good condition. This pipe combination is undersized and recommended to be replaced with a 10' by 3' box culvert or equivalent. This replacement, in conjunction with the other recommendations in this report,will alleviate the periodic flooding upstream of Foster Street. Estimated cost: $120,000 MILLER ROAD (POINT D) Although they are in good condition,the existing twin 24"RCP's at Point D are undersized. They should be replaced with a 10'by 3'box culvert or equivalent. Estimated cost: $80,000 MILLER ROAD(POINT E) A 8'by 3'box culvert is required to replace the existing twin 36"RCP's at this location. It will be necessary to raise the grade of Miller Road about two feet to keep the 50-year flood from overtopping the road. Estimated cost: $110,000 ABBE ROAD (POINT F) The existing 6'by 3'box culvert at Abbe Road is in good condition. It is recommended that the minimum elevation of Abbe Road be raised about two feet in this area. With the raising of the road, the existing culvert will provide adequate capacity and one foot of freeboard. It appears the road can be raised without adversely impacting abutting properties. Estimated cost: $15,000 20 ELLINGTON ROAD (POINT G) The existing 15" CNT is in fair condition with the asphalt coating mostly gone. Assuming a 25 percent diversion of flows at Point B, this structure should be a 4' by 2' box culvert or equivalent. Assuming no split,the road would only be overtopped by about 0.2 feet in a 50- year storm with the existing pipe. Estimated cost: $100,000 PRIVATE DRIVEWAY(POINT IT) Currently there is a 15" CMP under the driveway at Point H. It is more than half plugged with debris and its structural condition is unknown. With a 25%diversion of flows from the Podunk River watershed, this structure should be a 4' by 2' box culvert or equivalent. Assuming no split,the road would not be overtopped in a 50-year storm with the existing pipe. Estimated cost: $60,000 BEELZEBUB ROAD (POINT K) Avery Brook enters a 30" RCP north of Beelzebub Road. The 30" pipe enters an inlet structure. A 36" RCP exits the inlet structure and discharges south of the road.

There are a number of reasons why this is the wrong use for that site, but we will deal solely with the aMcts on the inland wetlands and nearby groundwater. The site is just 400 yards away from the Podunk River on two sides, to the north and the west. There was testimony at the December 19,2001 hearing that the site was over an area with considerable clay, and that groundwater would flow over that clay. Presumably, any solvents or other pollutants from the site would flow toward the Podunk River, and also through the groundwater toward the Chapel Road neighborhood, where the homes have individual wells. From comments at the hearing, it also appears that homes on Park View Drive also have individual wells. In addition, sediment from crushed materials flowing away from the site would likely silt the Podunk River. As you are probably aware, the Connecticut River Watershed Council and the Department of Environmental Protection are working on building a fish ladder at the Mill on the River. It would be unfortunate if their efforts were undermined by pollution and siltation of the Podunk River. We are concerned about some comments at the December 19 hearing that seemed to take a crimped view of your agency's authority. In fact, your agency has broad powers to protect the wetlands within the town Inland Wetland/Watercourse and Conservation Regulations, and the Connecticut Supreme Court has repeatedly found that the state Inland Wetlands and Watercourses Act gives municipal wetlands agencies wide discretion to exercise similarly broad powers over activities affecting the wetlands and water courses, whether or not those activities are actually in the wetlands. wetlands. has also been upheld by the Connecticut Supreme Court in Mario v. Town of Fairfield-' and CiotToletti v. Planning &&niRg Commission ofthe Town of Ridgefield It is apparent that the captioned application will involve activities taking place in the designated buffer area -- as well as in a nonwetland area--that will have a very serious affect on adjacent wetlands, on the Podunk River and on neighboring ground waters. The river is likely to be affected by silt and pollutants, and the groundwater is likely to be affected by spilled pollutants flowing through the groundwater over the impermeable underiving layer of clay, and into neighboring wells. The agency clearly has the authority to prevent this impact by denying the application. We hope the agency accepts the responsibility that goes with that authority.

The Project area is located within the Town of Town of South Windsor and is comprised of culverts, and their immediate surroundings,located on Miller Road, Route 74,Beelzebub Road,and Foster Street. The approximate site location is shown on Figure 1. The purposes of the investigation were to: delineate on-site wetlands in the vicinity of the proposed roadway crossing so that design work could be_considerate of this regulated resource,and;to provide an overall description of the natural resources that the wetlands provide that could also be used in site planning and determination of methods to minimize impacts due to culvert replacement. Wetlands were delineated according to the State of Connecticut statutory definition as described in Section 22a of the State Statutes and cited in the South Windsor Inland Wetland Regulations. Wetlands were delineated with sequentially numbered blue and pink flagging tape and the wetland boundary is shown on plans titled"Miller Road Drainage Design, Town of South Windsor Department of Public Works, Weston and Sampson Engineers,Inc. September 2001 Miller Road Drainage Design,Town of South Windsor Department of Public Works,Weston and Sampson Engineers,Inc. September 2001". The wetland functional values are described in further detail in this report. This report begins with the broad-brush view of the site.A description of the various natural resources including sections on the geology and soils,vegetation,and wildlife is used to provide information necessary for planning purposes. This information is then synthesized in summary section. Site Setting The site is located in Hartford County in the Town of South Windsor Connecticut,on Miller Road,Route 74,Beelzebub Road, and Foster Street. The local ecological context of this area,termed the North—Central Lowlands eco-region,has been described in Dowhan and Craig(1976). "A broad interior lowland, lying from 25 miles to more than 50 miles from the coast, characterized by extensive floodplains and lowland areas adjacent to the major rivers and interspersed with prominent north-trending ridge systems. Elevations are generally 50-250 feet above sea level,reaching a maximum of almost 950 feet on several of the rock ridges. On the west-facing scarps of the ridges is the maximum topographic relief,nearly 700 feet. The bedrock is sedimentary and igneous(red-brown sandstones and dark basalts)of Triassic age, in layers tilted to the east. The trap rock ridges, erosion resistant basalt layers, form an almost continuous belt of north-trending upland through the central and 1 z t ea � .ii• -3 � � ' �� J � � � t t �r�� J � tt i y y �X3 8 t ..« ` n, PA � 1 Scale: 1N=2000' N Figure 1 EP&SS LLC Site Locus Map 49 Lynn Road E Miller Road Drainage Design fvoryton CT Town of South Windsor Source: CTDEP S South Windsor, CT western parts of the region. Soils are developed on the red,clayey glacial till in the upland areas,and in the valleys and river-bottom areas,on extensive deposits of stratified sand, gravel,and local deposits of clay." The Miller Road site is within the limits of North—Central Lowlands eco-region and is true to the characteristics described above. The project locale lacks the trap rock ridges typical to the region and is instead located in one of the valley-river bottom areas that have soils formed mostly in stratified deposits. The surrounding land use is a mosaic of residential development,farmland,and forests. While recent development has converted much land to residential use,significant forested areas remain. Surficial Geology and Sons Southern New England was overlain by glacial ice as recently as 12,000-15,000 years ago. The materials that the glaciers deposited over top the local bedrock determine the surficial geology of the region and of the Miller Road site. Glacial deposits are generally divided into three categories:glacial till(un stratified sand,silt and rock),glaciofluvial (water sorted, stratified sand and gravel),and glaciolacustrine(stratified sand, silt and clay that settled out in lakebeds). The types of glacial deposits present on the site are glacial outwash,.glacial till. Alluvium-recent,.stream-deposited material-is also present as well as organic soils formed in decayed plant matter. Figure 2 shows the various types of soils,as defined by NRCS,which are present in the project area. Also present on the project site,and found most frequently in the areas of the culverts to be replaced,are Udorthents. These are areas of altered soils that,within the project area,were previously disturbed during road construction. Appendix A, Soil Scientists Report,goes into greater detail regarding project area soils Vegetation and Cove,r Types As mentioned in the Site Setting section above,the Miller road site is within the Southeast Hills eco-region. Dowhan and Craig(1976)provide a description of typical vegetation found in this eco-region. "Major regional forest vegetation on`typical'well drained soils is the Central Hardwoods-Hemlock-White Pine. Characteristic tree dominants include Red, Black and White oaks(Quercus rubra, Q. velutina,and Q. alba),and Shagbark,Pignut and Bittemut hickories(Carya ovata, C. glabra and C cordiformis)" The upland forests on the site are typical to what Dowhan and Craig described.

This list reflects-the diversity of habitats(cover types)present on the site. The presence of extensive,mature woods including both deciduous and conifer-dominant types,along with different wetland habitat types, and edge habitat created by roads and trans,causes this site to provide excellent wildlife habitat for a diversity of species. Despite development pressures and dwindling open space, Connecticut has thriving populations of mammalian wildlife species. The reversion of fi mland back to forest has been the most common land use change in the state. This has created sufficient habitat for many species,such as white-tailed deer and wild turkey,to prosper on a statewide level. While the area surrounding the Miller Road site has been subject to residential development the mixture of cover types provide good wildlife habitat as indicated by the diversity of species listed. Wetland Assessment and Impacts A wetland functional assessment was conducted for the six areas of proposed impact due to culvert replacement. The assessment was conducted using the United States Army Corps of Engineers(USACOE)Highway Methodology. The assessment data forms are presented in Appendix C. This method was originated by the USACOE and is particularly appropriate to roadway planning. For clarity,in the following table is presented to summarize the findings of the functional assessment.

As can be seen on Figures 1 and 2,the wetland system contains broad areas of wetland soils, streams that flow into and out of ponds,and broad forested wetlands upstream and downstream of the project area. Numerous habitat types are present including open water, emergent marsh, scrub/shrub swamp, stream,and wooded swamp.As shown in Appendix D,this wetland complex was found to provide numerous functions including: groundwater recharge/discharge,fish habitat, flood flow alteration, sediment/toxicant reduction,nutrient removal,production export, sediment/shoreline stabilization,wildlife habitat, recreation, educational/scientific value,uniqueness/heritage and visual/quality aesthetics. Based on the functional assessment preformed,this wetland provides many important wetland fiunctions. Proposed Impacts As shown on the project plans submitted as part of the application,approximately 8135 square feet of wetland will be filled to meet the project purpose. The impacts (temporary and permanent) are discussed below- in light of the functional values provided by the wetland. Impacts that might be expected from a culvert replacement project are listed and discussed sequentially below and include: • Direct loss of wetland functions and habitat due to elimination of wetland through Ming • Loss of bank stabilization due to loss of vegetation and sedimentation and erosion during construction • Loss of wildlife habitat due to loss of vegetation and wetland area 4 • Alteration of wetland hydrology and flood storage capacity • Alteration of the groundwater recharge discharge function due to alteration of wetland surface soils. This project has been design to have minimal direct loss of wetland. Note(Refer to the project plans) that while approximately 8135 sf of wetland will have fill placed within it, the vast majority of this area will remain as stream habitat,similar to what currently exists. As a result, minimal direct loss will occur. Construction will require temporary loss of vegetation in and around the wetland. Disturbed areas are shown on the project plans (Attachment B). Project plans also document semen and erosion control measures to be in place at each location, and show a dewatering plan for each site that will handle the peak flows from a two-year recurrence interval storm While the potential for erosion exists, timing of construction (during dry months)will further reduce the hlkeh'hood of it becoming a problem The wildlife habitat value of the wetland systems within the project areas is high. The wildlife habitat available within the proposed areas of impact is lower than that of the overall system due to the proximity roads, culverts, and houses. The primary impact to wildlife habitat is expected to be temporary displacement of wildlife during conshvction. Auer construction, wildlife will be able to re-occupy the same habitat that was previously available. No significant hydrologic alterations or loss of flood storage capacity is proposed. The sites of the. culvert replacements will maintain existing invert elevations at inlets and outfits and generally be made to quickly match into existing grades upstream and downstream of the construction areas. Thus there will be no significant change in flood storage or water surface elevations at any of the culvert replacement sites. Groundwater dise1mgetrecharge is typically a fiuuction of wetland/stream bank surface area, porosity of souls, and the size of the area feeding the interface. The changes in surface area and characteristics of the soil material cover a very small area and no changes in the re- chargeldischarge function are anticipated. Alternatives Two alternatives were considered for this project: the no-build alternative and the preferred alternative as presented in this letter and on the project plans. The no-build alterative would consist of doing no drainage improvements and leaving the culverts and associated wetlands and watercourses unaltered The preferred alternative has been outlined above and would result in the filling of 8135 s.f. of wetland with 609 c.y. of fill and would alleviate flooding problems throughout the project area The no-build alternative would not accomplish project goals and would do nothing to alleviate existing flooding problems. The flooding problems would continue and potentially worsen due to future development of land within the local watersheds. The potential safety concerns, e.g. limitation of emergency vehicle access during flooding, and flooding threats to residents, 5 would remain. The no-build alternative is considered unacceptable due to its lack of ability to protect the public safety. The preferred alternative is proposed as a means to accomplish the project goals with minimal short and long tern affect on environmental resources. The areas to be disturbed.due to culvert replacement are primarily beneath exiting roads or in areas impacted by installation of the existing culverts. The impacts have been rnnanized so that the only alterations to wetlands and watercourses are those necessary to provide culverts of adequate size to carry the flows and provide for inlet and outlet protection for the new culverts. The areas where nprap protection will be placed are typically occupied by pools with sand and or rip rap already As documented in the drainage study and memos, the proposed action will significantly reduce the potential for flooding at the project site, assisting the residents in protection their safety and property.. The drainage improvements proposed will also help to maintain emergency access within the project area. Based on this information,the preferred alternative was chosen as a means to accomplish the project purpose and need with minimal impacts and is therefore the most feasible and prudent alternative. Summary Approximately 8135 square feet of wetland will be filled to provide necessary culverts and inlet/outlet protection. There will be no significant loss of wetland area or fiuiction as a result of this project. In fact,the total area of wetland will remain generally unchanged because the area of proposed fill(i.e.riprap)will still be within the stream channel and continue to maintain wetland hydrology. The project design presents the most feasible alternative to accomplishing the goals of protecting infrastructure and public safety. If construction is properly performed, there should be no significant impact to the wetlands. 6 References Dowhan,I D. and R.3 Craig. Raze and Endangered Species of Connecticut and Their Habitats.

At your request, I have conducted on-site ins to determine if State of Connecticut wetlands or waterroourses regulated under CGS See. 22a-36 et. seq. are preserit on a site curren*being considered under the South Windsor Dq=tnxwt of Public Works Miller Road Drainage Design Project. The investigations were completed in the fall of 2001 using a hand- held auger and revealed regulated wetlands and at each of the proposed activity sites shown on the project plans. Wetlands ad watercourses were Bagged using Pink and bh w flagging tape, and my review indicates that the locations of these flags, as shown on the project Plans,are representative of what I delineated in the field. The types of glacial sedime2ts present on the site are glacial outwash and glacial till. Anuvium-recent, stream dspositad material- is also present as well as organic soils formed in decayed plant matte. The attached map shows the various types of soils, as defined by NRCS,which are present in the project area. Also present on the project site,and wand most f vquen* in the areas of the cuhuU to be replaced, are Udordzm ts. These are areas of altered soils that,witbin the project area,were previously disturbed during road construction.

These soils are predominantly located along the lower reaches of Podunk River and Avery's Brook and are regulated as wetland soils. Glacial outwash soils are located next to, and above the alluvial soils within the project area. Glacial till soils are typically above the outwash soils within the project area The organic soils(e.g. Carlisle) are found in the lowest area in the middle of the broadest wetlands. The soils around the proposed work sites invariable had profiles indicative of disturbance. This was expected due to the proxinuty of the roads existing doss culverts. Based on the locations of the proposed work, I antleipate that relatively small areas of natural soils will be disturbed. Due to the need to work in and around stream channels that already have sediment deposits,I recommend that the work be done during dry times of year and that site specific do. watering and sedimentation and erosion plans be prepared.

Engineering Reports Prepared by WSE Inc. and CME Associates Inc. PERMITTING REQUIREMENTS Impacts to wetlands and/or watercourses at each culvert replacement location were estimated and cumulative impacts were analyzed to determine the permits that may be needed to satisfy local, state, and/or federal regulations. This analysis was performed using preliminary data that will need to be refined when final design decisions are made. Table 9 illustrates preliminary estimates of wetlands and watercourse impacts at each location. An overview of the pertinent local, state and federal permits is included to allow for a better understanding of the separate jurisdictions held by each agency. SOUTH WINDSOR INLAND WETLANDS AND WATERCOURSES AGENCY Inland Wetlands and Watercourses Permit-The Town of South Windsor regulates any activity that is within 40 feet of a wetland or within 80 feet of a watercourse. Local approval needs to be obtained before state or federal approval will be given. The limits of wetlands and/or watercourses at each replacement location should be field-delineated and located to accurately define the resource area limits. A single application should be submitted to the Inland Wetlands and Watercourses Commission for all culvert replacement locations for review and approval of cumulative impacts. There are no fees assessed by the local agency for Town of South Windsor projects. STATE OF CONNECTICUT DEPARTMENT OF ENviRoNMENTAL PROTECTION Water Diversion Permit-The Bureau of Water Management's Inland Water Resources Division(IWRD)regulates activities which cause,allow or result in the withdrawal from or the alteration, modification or diminution of the instantaneous flow of the waters of the State.Replacing existing culverts at the specified locations with larger structures will 23 relieve backwater flooding. It is unclear at this point whether this constitutes a "diminution of the instantaneous flow"of the streams being conveyed. The project hydraulic analysis of each culvert replacement location should be submitted to the IWRD for preliminary review to determine if a water diversion permit would be required. If a water diversion permit is required,the application fees are dependent on watershed size. Therefore,two Water Diversion Permit applications would be submitted for this project; one for the Podunk River drainage basin and one for the Avery Brook drainage basin. The watershed size of the Podunk River to Point F is approximately 1.12 Square Mile. The initial fee for this application would be $1,250. The watershed size of the Avery Brook to Point K is approximately 0.17 Square Mile. The initial fee for this application would be $600.These are initial fees. CT DEP may assess further fees during the review process. 401 Water Quality Certificate—Any applicant for a federal license or permit, including a dredge and fill permit from the U.S. Army Corps of Engineers, must obtain a permit in accordance with Section 401 of the Clean Water Act. This federal permit approval process is administered through the state. Water Quality Certification from the DEP is required if the proposed activity may include discharges to navigable waters. DEP's Bureau of Water Management Inland Water Resources Division regulates any activity that may result in a discharge into the navigable waters, including all wetlands, watercourses,and natural and man-made ponds.There are no initial fees assessed for this application package. Projects having less than 5,000 square feet of cumulative impact to federally regulated inland wetland and watercourses fall under Programmatic General Permit (PGP) Category I activities. These activities are non-reporting due to their minimal impacts and no application needs to be submitted to CT DEP for approval. 24 Projects that disturb between 5,000 square feet up to one acre of federally regulated inland wetlands and watercourses are eligible as PGP Category II activities. Category II activities are reviewed by the Corps and CT DEP at a joint screening meeting. If the application receives unanimous approval from these agencies, written notification will be granted by the Corps of Engineers. A separate application for a 401 Water Quality Certificate does not have to be submitted to CT DEP. Projects that disturb over one acre of federally regulated inland wetlands and watercourses are required to submit an application for a 401 Water Quality Certificate to-CT DEP as well as an application for an individual permit from the U.S. Army Corps of Engineers. Preliminary cumulative impact estimates for the project are noted in Table 9. U.S.ARMY CORPS OF ENGINEERS . Any applicant proposing dredge or fill activities within "waters of the United States, including wetlands" must obtain a permit in accordance with Section 404 of the Clean Water Act from the U.S Army Corps of Engineers. Corps regulations apply to both permanent and temporary impacts. A description of the impact review thresholds is provided below. Category I Activity-Category I activities are any temporary or permanent impacts of up to 5,000 square feet of federally regulated inland wetlands and watercourses without applying for a permit. These activities are regulated by the local inland wetlands and watercourses agency. Category II Activities- Category II activities are from 5,000 square feet to one acre of impacts to inland wetlands and watercourses. These activities require review at a screening meeting between the U.S. Army Corps of Engineers and CT DEP. A 401 Water Quality Certificate is issued to validate the federal permit. Local IWWC approval needs to be obtained before these activities can be approved. 25 Individual Permits - Activities that affect more than one acre of federally regulated wetlands and watercourses require that an application for an individual permit be submitted to the U.S. Army Corps of Engineers. This also requires a separate application to CT DEP for a 401 Water Quality Certificate. Table 9 indicates that the total project impacts will require Category H screening for approval. One application should be submitted to the Corps for all project impacts to allow for a complete review of the project and save time and effort in permitting. 26 TABLE 9: WETLAND IMPACTS ESTIMATED LOCATION IMPROVEMENT WETLAND DISTURBANCE (square feet) A 2-48" RCP's <2,000 B none --- C 10'x 3'box culvert <2,000 D 6'x 3'box culvert <2,000 E 8" x 3" box culvert <2,000 F Raise road, maximum of 2' <1,000 G 4'x 2'box culvert <1,500 H 4'x 2 ` box culvert <1,500 I none ---- none ---- K 8'x 3' box culvert <2,000 27 MEMORANDUM TO: JEFF DOOLITLE, TOWN ENGINEER FROM: JEFF FOLGER, ENVIRONMENTAL PLANNER DATE: 4/12/02 RE: PLANTING RECOMMENDATIONS FOR DISTURBED AREAS ASSOCIATED WITH THE CLARK/PLEASANT VALLEY, AND MILLER ROAD APPLICATIONS GROUND COVER: 10% RED CLOVER; 40% TALL FESCUE, 50% LITTLE BLUESTEM SEED RATE 120#/ACRE SHRUBS: 20-FOOT CIRCLES; WITHIN THE CIRCLES IN WETLAND AREAS AND WITHIN 25 FEET OF THE WATERCOURSE: WINTERBERRY SILKY DOGWOOD (COMBINED GROUPS OF TEN EACH 2 FEET ON CENTER) IN UPLAND AREAS FARTHER THAN 25 FEET FROM THE WATERCOURSE: SERVICE BERRY AMERICAN CRANBERRY BUSH (COMBINED GROUPS OF FIVE EACH 2 FEET ON CENTER) 4pwM af� t� a u 1540 SULLIVAN AVENUE • SOUTH WINDSOR, CT 06074 soR•co��� TELEPHONE (860) 644-2511 May 3,2002 Town of South Windsor Attn: Jeffrey Doolittle 1540 Sullivan Avenue South Windsor, CT 06074 RE: Appl. #02-05W—Town of South Windsor,Beelzebub Road, Foster Street Extension and Miller Road Dear Mr. Doolittle: At the May 1, 2002 regular meeting,the Inland Wetlands Agency/Conservation Commission approved application#02-05W—Town of South Windsor—Inland Wetland/Conservation Commission application for drainage improvements to replace road culverts at stream crossings on Beelzebub Road,Foster Road Extension, south of Miller Road,and Miller Road, east of Abbe Road.
