HomeMy WebLinkAboutCommunication regarding high water table C 116 Edgewood Drive S. Windsor, CT 06074 C, December S, 1965 South Windsor Town Manager -Town Hall , S"ulivan Avenue South Windsor, CT 06074 Drar Mr. Sartor : This letter is mainly to thank you for your attention to the water table problem that I first wrote to you about on October 11 . To begin with, I was glad to have the opportunity to meet with you a few weeks ago and discuss various aspects of this situation in person. It was obvious that you were informed on the subject. Secondly, I received a copy of the 1582 ground water study from the Town Engineer. Thirdly, I was told by Phil Braender that you had inquired about the map I mentioned which shows an underground stream passing through my property. He also mentioned, as did Mr. Martel's letter, that the possibility of connecting my footing drains to the nearby storm sewers is being investigated. I have a few comments concerning the study entitled "Groundwater Conditions of the Parkcentre Development, South Windsor, Connecticut" . It referred to an "accompanying map" which was not included with the copy I received. The study seemed to me to be somewhat vague and undefinitive. (Five pages were devoted to the study itself, and ten pages were devoted to Environmental Management Counselors and the three consultants. ) Perhaps the most interesting item in the report were two references to ditches that substantially lowered the water table in their immediate vicinities. Can future earth-moving activity in Parkcentre include such ditches near our neighborhood, especially near my property? I have continued to think about the "randomness" of the water table height over the years, and I must say this: The level of the water table, as observed in my sump hole, has been reasonably commensurate with the time of year and magnitude of precipitation throughout the twenty years I have lived in this house. . . .until this summer! I still believe that the likeliest explanation for this unprecedented water level is that earth moving activities in Parkcentre have affected drainage, quite possibly altering the flow of my infamous underground stream. I hope to explore this theory further, and I certainly wouldn't mind if the Town did the same. I look forward to hearing from you when further information has been developed. I very much hope that the efforts being expended to explore this problem will lead to concrete steps to alleviate it. Thanks again, and have a happy holiday. \ Sincerely yours, J Stan ey Greenberg r � a / n TB./X `78.0 / d-/X E.190,744.29 E.190,395.55 00 l/ -7.,5I ✓.�N/F A +V 8 TRUDYJ6 0 /F LF UZ ETH d 78.6 v, 1 \ 79. ro / L =27' 7..

Windsor, CT 06074 October 29, 1965 South Windsor Town Manager Town Hall, Sullivan Avenue South Windsor, CT 06074 Oear Mr. Sartor: Thank you for your October 23 reply to my letter of October 11 . I appreciate the fact that you consulted the Town Engineer and gave consideration to my problem. However, I must concur with your closing comment to the effect that "this is not the response you would have preferred" . The purpose of this letter is to respond to some of your statements and to emphasize some points that do not seem to have made a sufficient impression. First, I cannot accept the suggestion of the Town Engineer that because rainfall this summer was "significantly above normal" , the presence of water in my sump hole is reasonable. I have lived in this house for 20 years, and we have certainly had wetter summers (following wetter winters, in fact) , but my sump hole has never before had several inches of water from midsummer through October! Something is different now. Secondly, I suggested that the only factor that I know of that may have altered the hydrogeology of this erea is the activity in parkCenter . I think this is a pretty good theory, but you ignored it in your reply. Thirdly, you mentioned the possibility of negative effects on wells and/or the use of land for agricultural purposes if the water table were lowered. This possibility simply does not exist because: (1) Almost everyone around here has city water. (2) The water table seems to be within four or five feet of the surface (at least on my property) now. Lowering it to ten feet beneath the surface will hardly hurt anyone who counts on the availability of underground water. Fourthly, I said that the water table in this area has risen to the point where it probably fits the definition of "inland wetland" . I would think that this alone bears looking into on the part of the Town. Your letter of October 23 made no mention of this point. Fifthly, I indicated that the Tolisanos, who live across the street, have also observed water in their sump hole which is even more unusual than in my case. I must reiterate that they are very concerned and are as anxious as I am to press this matter. Ate Therefore I am again requesting, on behalf of myself and Mr. Don Tolisano, that the Town pursue this matter without delay and take concrete steps to lower the water table in this area by several feet. I must repeat my October 11 statement that citizens of this Town should not be victimized by events that should not have been allowed to occur in the first place. I look forward to hearing from you soon. Thank you.

SARTOR Town Manager October 23 , 1985 Mr . Stanley Greenberg 116 Edgewood Drive South Windsor , Connecticut - Dear Mr . Greenberg : Thank you for your letter of October 11 , 1985 , in which you express concern with regard to the water table in the area of your home . As you noted in your letter , for many years you have periodically been required to pump groundwater that gathers in the sump that was designed and intended to protect against water in your basement . A sump pump is , of course , a standard feature in many homes in South Windsor--because of the necessity for this type of protection . In your letter , you specifically refer to the fact that your sump has , in past years , generally been dry throughout the Summer and Fall months ; and that you are concerned because , this Summer , groundwater seeping into your sump has required pumping . I have discussed this matter with our Town Engineer , and he has indicated that--although it is correct that drought conditions existed from last Winter through the Spring months of 1985--we have found that , during the Summer months , rainfall has been significantly above normal . Therefore , it is to be expected that the groundwater level would rise . The Town Engineer has , therfore , indicated to me that sufficient cause does not exist to consider a hydrogeological study , of the scope that would be required , based upon the information you have provided . There is , additionally , a concern on the Town ° s part that , should steps be taken to attain the goal you desire (i . e . , lowering of the water table) , there could be a significantly negative effect on wells and/or the use of land for agricultural purposes . I realize this is not the response you would have preferred ; however , I believe it would be misleading to indicate otherwise . Very truly yours , T.o n Mana 19 r RJS :prb 116 Edgewood Drive S.

It has to do with the level of the water table. My family and I have lived in this house for twenty years. Almost every year, the water table rises in the late winter and spring to where my sump pump is all that stands between us and a flooded basement. (The basement is fully finished, by the way. ) ' This has been a rather nerve-wracking situation, and I often wondered if I should try to enlist the Town's aid, 'but I did not. Throughout the years, my sump hole has always been bone dry during the summer and fall, which was at least a bit of a relief. However, since mid-summer, my sump hole has had several inches of water, the exact level varying with the rainfall situation. Furthermore, my across-the-street neighbors (the Tolisanos) also have some water in their sump hole which is slower to have water than mine. I would have found this suddenly higher water table worrisome under any circumstances; but when you consider that this is supposed to be a drought situation, it's downright alarming. I have also learned that several trees that were uprooted by hurricane Gloria showed signs of "root rot" due to wetness. There seems to be no question that the water table in this area has risen to the point where it probably fits the definition of "inland wetland", if it did not already qualify as such. The only "theory" I can offer to explain this scary development is that activities in ParkCenter (as it was once called) have impeded the drainage for this area. Indeed, Nutmeg Road now connects with Newberry Road, and perhaps it is cutting off the flow of underground water towards the river. 4t40 i2 tom ! R In any event, something is different than it was before, and there must be a reason for it. We have very good cause for concern. A number of homes in this neighborhood have had ground water problems over the years. And I personally shudder to think of what may happen during the upcoming "pumping season Therefore I am requesting, on behalf of myself and Mr. Lion Tolisano, that the Town pursue this matter without delay and take concrete steps to lower the water table in this area by at least two feet. (Five feet would be better! ) I realize that this is not a trivial request, but citizens of this Town should certainly not be victimized by events that should not have been allowed to occur in the first place.

To the east is a residential development i called Pleasant Valley Estates. Both the industrial park and the residential development have a history of high groundwater problems. jl EMC, Inc.- was asked to investigate the groundwater situation in and I i near the industrial park and to determine what effect, if any, the activities in the park, past and future, might have cn the ground- , water in the adjacent residential area. This report was prepared by Dr. Charles Wm. Di=ick, a Certified Professional Geologist, whose background and credentials are attached �l to this report for informational P purposes. Materials used in prepar- ing this report include boring data obtained by Engineering Services, Inc. , Glastonbury, Connecticut (Clarence Welti) in September of 1967 �l and by Geotechnical Consultants, Inc. (on contract to Purcell Asso- ciates, Glastonbury) in June, 1976 . Pertinent data from the boring a logs is included in Table I and test hole locations are shown on the I accompanying map entitled, "Groundwater Study of the Parkcentre Development. " Y Geology and -Soils The entire .area is underlain by old lake bed silts and varved :a clays on top of which are 12 to 20 feet of alluvial and glacial i 2. outwash sands. The top. of the varved clays is remarkably flat (about 3 ft. variation In elevation) and the variation of sand thickness is mainly a reflection of surface topography. The soils which have developed are a reflection of topography and depth to groundwater. All of the soils show. presence of a seasonal high water table. Where this seasonal high water table is more than a foot below the surface, Sudbury and Ninigrit fine sandy loams have developed. Where the seasonal high water table was historically at i or almost at the surface, Walpole fine sandy loams developed; and where the water table stayed high y g year-round, the very poorly drained Scarb,oro• loams developed. Long use of the land for agricultural pur- poses included partial drainage of the wetter areas, but this has not changed the basic soil characteristics. Recent construction activi- ties have involved massive redistribution of the surficial materials over much of the site, making it difficult to determine in the field what the original soil conditions were. Thus, for this report, we have depended on the February 1962 Soil Survey of Hartford County, Connecticut and the "South Windsor Inland Wetlands and Watercourses" map of March 1974 for pre-construction conditions. Groundwater Conditions Inspection of soil and topographic maps reveals that ground- water would have been very near the surface, nredevelopment, on both the industrial site and the adjacent residential site during the wet seasons. Much of both areas are underlain by poorly drained and very i Poorly drained wetland soils. Groundwater would be at its highest 3 Mr- 3. elevation -(about 78 ft. ) just north of the playground N.W. of Edgewood Drive, with the water table sloping to the south, east, and west. Within the residential development, the groundwater i would be highest (75-76 ft. ) just west of the north-west section of Judy Lane sloping to both east and west. The water table mounds under Barbara Road, sloping away in all- directions, and slopes both north and south from the lots lying on the south side of Judy Lane. Originally, the slope of the water table to the west was more to the southwest and was very gentle, about one foot vertical for every 300 foot horizontal, or a slope of 0. 34%. Two man-made constructions have changed the picture. The first was the digging of the old farm ditch which lies on the border between the industrial park and the residential area. This lowered the wet season water table as much as three feet in the I j vicinity of the ditch and Newberry Road. Except for those homes i within 200 feet of the ditch, it would not have had a significant effect on water levels within the residential area. The second change was the excavation of the area between .the old ditch and Newberry Road and the construction of a new ditch. This has dramatically lowered the wet season water table on the industrial site, in some places by as much as six feet; but the effects would probably not be noticed in the residential area except for a slightlowering of water levels in the backyards of the two homes just south of the playground. In summary, I ' none of the activities on the industrial site have i raised the water table on the adjacent residential area, nor have i 4. they cont=i=-uted t® a sicni_,icant lowering of the water table more than 200 =ee= =ram actual construction.

A consortium of biologists , ecologists , geologists , soil scientists , and hydrol- ogists applied their various skills to facilitate and coordinate environmental decision-making at the community level . The task was accomplished by advising the various community conservation and wet- land agencies involved . At the end of the 12-month funding period , requests for assistance continued and resulted in the formation of a private firm - Environmental Management Counselors . EMC provides comprehensive services in the development of a complete site analysis including mapping of site characteristics , engineering evaluation , special feature delineation geological analysis and aquatic studies , each of which are appropriately documented as a matter of procedure for each site investigation . The following is a sample list of applicable projects that have been undertaken by EMC staff consultants in recent years : 1 .
