Dunphy Drive/ Maple Ridge Drainage Report/Complaint 1986 A REPORT FROM THOMAS E. RICE 1CONSULTING GEOLOGIST Prepared for: Date: July 13, 1986 Charles & Kathleen Pysz, Jr. 95 Dunphy Drive Northampton, MA. 01060 and Linda & Robert Wheeler 75 Dunphy Drive and Gary & Kathleen Houle 103 Dunphy Drive In response to your concern about the possible impact of a proposed subdivision on drainage conditions at your homes and in your yards, as well as those of your neighbors on Dunphy Drive, I have prepared the following 3—part report. Past and Present Drainage Problems and Cause: In the past each of your homes on the north side of Dunphy Drive has experienced problems caused by excessive runoff and groundwater flow from the north. Presumeably other homes along Dunphy Drive have had some degree of problem with runoff and groundwater flow, depending upon their location. Excessive groundwater flow and surface runoff nave led to inoperable and flooded leach systems and basements, and has caused each of you to expend thousands of dollars to partially correct the problem with subsurface drains. My observations on Thursday evening indicated to me that the water table near your homes is, and has been, close to the surface. The depth at which the house foundations are set is less than standard depth, indicating that the original builder encountered a shallow water table. The lack of footing drains around each foundation aggravated the flooding problems following every period of heavy precipitation or snow melt. The installation of footing drains when the houses were built would have 2 prevented most of the oellar flooding, but might not have stopped the flooding of leach fields �(nd septic tanks. The placement of the septic systems on the uphill sidd of the foundations is contrary to good practice, especially when the sub—surface stratification sloped toward the foundation. The excavation for a swimming pool beside the Wheeler's home shows the sloping beds of sediment, and also encountered the water table at a depth of about 7.5 ft. on July 10, 1986. The workmen had been pumping water from the excavation during the afternoon while they were working, so the water table may actually be closer to the surface that it was when I observed it. 1986 precipitation through June was 21.5 inches, which is almost exactly one half of our average annual precipitation. however, 13.1 inches of that total fell before April, and the total for the past 3 months was only 8.4 inches. The drier 2nd quarter has depressed all water tables, especially since it coincides with the beginning of the growing season when vegetation draws water from the water table. In a wetter 2nd quarter the water table would be even closer to the surface. Iron staining in the beds of sediment suggest that it normally is only about 4.5 feet below the surface. Uphill from your homes there is abundant evidence of surface runoff coming from farther uphill as well as from the uphill portions of your backyards. It was difficult to determine the uphill limit of that surface runoff, but it seemed to coincide with the downhill edge of the coarser sand and pebble gravel that occurs a short way uphill from your property lines. It is probable the runoff from the large hill north of your homes enters the coarse sand and pebble gravel at the base of the hill and then emerges from it just uphill from your property to flow downhill across your yards. Map 1 which accompanies this report shows the location of Profile Line AA' . The southern end of the line at A' is approximately tue location of Dunphy Drive, and the line passes through the area of your homes to the top of the large hill: Figure 1, which also accompanies this report, is the topographic profile along the line AA' across Dunphy Drive and down to the 260 ft. contour line. Vertical dimensions are exagerated by a factor of 10:1: Horizontal dimensions are at map scale. The vertical exageration makes the hill look like a mountain, but it makes it possible to put into 3 perspective a smaller landform upon which your homes and Dunphy Drive are located. Beginning just I elow the 300 ft. elevation there is a elope break in the profile: from the ill slope to a nearly horizontal surface. This is followed by a second slope break at the south edge of the horizontal surface to a gentler, concave upward, elope that leads down to elevation 260 ft. I have projected the continuity of the hill slope below the topographic profile to complete a cross—section of the smaller landform. I have shaded that cross—section in red to emphasize it. This smaller landform is a small glacial outwash delta that was built into Glacial Lake Hitchcock and against the base of the large hill. Figure 2 is also a topographic profile along the line AA' . I have redrawn it to expand the horizontal dimension and to remove the vertical exageration. It shows the slopes as they are, though reduced in scale. I have included it to illustrate that the presence of the small glacial delta would be un—noticed, except by someone trained to recognize its surviving features. Again I have shaded the deltaic feature to emphasize it. Figure 3 is a generalized blow—up of the portion of Profile AA' that contains the small glacial delta. I have indicated three parts of the delta with the letters A, B, & C. The delta was built (deposited) from A toward C. The sediments in the vicinity of A are the coarsest sediments in the delta. They were deposited there because they were too heavy to be transported farther into the lake by currents from the stream that built the delta. The sediment sizes here are mostly coarse sand (1/16 in. ), grannules (1/8 in. ), and pebbles (1/4 — 3/4 in. ). The buried beds slope toward Dunphy Drive, but the upper beds which were spread over tne lower beds are very near horizontal. These upper near—horizontal beds are called tne topset beds of the delta. Along the base of the large hill there is a sharp slope break that shows where tnese beds were washed in against the base of the hill. These topset beds were above the level of the lake, and the meltwater streams that built tae delta added to them as they shifted course over the top of the delta. These beds are veiy permeable, and at present, runoff from the large hill enters these beds at the base of the hill. The water that enters the topset beds is then distributed to the buried beds that slope downhill toward Dunphy Drive. There is no evidence of any surface runoff crossing the area under- lain by these beds of coarse sediment. In Figure 3 the letter B indicates a broad area from the left of the . development boundary to Dfpby Drive. The land surface in this area is the eroded former face of the delta. This surface was originally beneath the surface of Glacial Lake Hitchcock. The beds of sediment beneath the soil cover slope downward toward Dunphy Drive at an angle parallel to the original slope of the face of the delta. I have indicated these beds with diagnal sloping beds that lines in the cross—section of Figure 3. These are revealed in the sloping are the excavation for the 'Wheeler' s swimming pool. They are called the foreset beds of the delta. The slope angle these beds is steepest near area A and diminishes under area C. Near Dunphy Drive the beds are sloping at about 30^ below the horizontal. Within the foreset beds of the delta the sediments are coarser toward This fining of sediments toward C foreset bed in areas A & B cannot of area A and become finer toward area C. means that water that easily flows into a flow easily at C. The result is that water is stored within these beds and there is a high water table near Dunphy Drive. Another aspect of these foreset beds is the alternating sediment sizes found in them. The excavation for the swimming pool at Wheeler' s home reveals that thick beds of fine sand The coarse and silt alternate with thinner beds ofcoarse sand and grannules. grained beds act as confined aquifer beds. They are capable of transfering water rapidly from the vicinity of A toward Dunphy Drive, but without an outlet they only hold water and release it slowly through area C. When excavations intercept those coarse beds the water in them can flow out rapidly. This was undoubtedly the reason for basement flooding before corrective drains were installed. South of Dunphy Drive in the area marked C the foreset beds have lower slope angles and contain much finer sediments: mostly silt with increased amounts of clay sized sediment. These are the conditions that impede drainage from these beds and contribute to the high water table uphill from Dunphy Drive. Map 2 gives the approximate location of Dunphy Drive. I have drawn in(blue lines) The outline of the various the proposed subdivision is shown. drainageways indicated by the contouring and know from our walkover that they are intermittent streams, and small perennial of tae U.S.G.S. topographic map, These include rills, I have outlined the there. streams. 5 part of the delta that I have observed, and have used red shading to indicate the upper part were the sediments are coarse and red lines for the finer grained foresetlbed area. The drainageways that lead to the brook that drains under Route 66 have eroded deeply into the original delta, altering its original shape until the deposit no longer resembles the , initial delta. Effect of Proposed Development: Runoff from the south and southeast sides of the large hill that is proposed for development has supplied the groundwater that has caused flooded basements, leach fields, septic tanks, and yard erosion along the northern side of Dunphy Drive toward the western end. About 37-42 % of the precipitation that falls on that hill at present flows downhill as surface runoff, 55-57% is consumed by evapotranspiration in the mixed hardwood/ evergreen forest and by groundcover and understory plants beneath the forest canopy, and about 1p' enters the water table on the hill. The hill is composed of compact glacial till over bedrock, and is a glacial landform known as a drumlin. Water infiltrates the compact till at very low rates, which facilitates increased surface runoff. Groundwater flow within the till is correspondingly very slow: published flow rates of 87-94 ft./yr. are usual. Baker Hill in the Bay State section of the city is a similar drumlin, and Bay State residents could tell you about their problems with runoff on that partially developed hill. Runoff from a forested drumlin is at a minimum. Development of drumlins increases the surface runoff because development reduces the water retaining characteristics of the ground cover within the forest. A substantial part of the hill involved in this development will be converted from areas covered with forest duff to areas of roofs, lawns, driveways and walks, and sub- division roads and sidewalks. Runoff from those new surface covers will be very high: 85-1004. In addition, new residents will further increase the surface runoff as they remove brush, leaves, and undesireable plant growth from the remaining forested area. The outlook can only be for faster and more runoff. Some of the increased runoff will be intercepted by the storm sewers and curbs of the subdivision roads. But Nap 2 shows that in the area _ 6 imediately north of Dunphy Drive the increased runoff will encounter the coarse—grained topset beds of the glacial delta. That water will infiltrate rapidly and increase the amount of groundwater in the sediments of the delta. .The foreset beds of the delta will conduct that graundwater under the subdivision road that will be constructed there, and lead it downhill toward the homes on Dunphy Drive. As a consequence of the changes in runoff and groundwater conditions, it can be expected that the water table will become shallower in the delta sediments. Some of the intermittent streams will flow for longer periods of the year. Some of the present rills will become intermittent streams. The flow in the present perennial stream will become less regular and subject to peaking. How this evevation of the water table will effect the existing homes along Dunphy Drive is hard to predict because some subsurface drainage has been installed by the homeowners. I think it is safe to predict that existing subsurface drains will carry larger volumes of water for longer periods of time. I don' t think it is possible to predict whether those - drains will have sufficient capacity to prevent a recurrence of the original problems. I would recommend that you devise aplan for monitoring flow from those drains so' that you will be able to document any increased flow after construction of the subdivision begins. Possible Solutions: You presently have a high water table, high groundwater flow rates, and surface flooding and runoff problems. The proposed subdivision threatens to increase all of those problems. The options available to you seem to be: 1. do nothing now and problem worsens, or 2. make city officials aware of past and present problems and of the threat of future problems, and to try to enlist their support for taking corrective steps at the time that this subdivision is constructed. prevent the worsening of install your own private drainage if the There are some tnings that can be done to your drainage problems, and possibly to reduce them. However, those steps which are beyond the requirements of the subdivision law would mean increased costs for the developer and are unlikely to happen unless the city picks up part of the cost. The first and most important corrective measure would be to out off groundwater flowing south from the north and northeast parts of the glacial delta. This could be done by installing a deep curtain drain beneath the subdivision road where it) crosses the delta. The small delta is not very thick where the roads will be built and it should be possible to trench through the delta into the glacial till. The curtain drain should be back filled with material that will allow the curtain of fill to intercept groundwater flowing in the aquifer beds and conduct it down to the perfor- ated drain pipe. The grades along the subdivision roads are favorable for draining the curtain drain to the small perennial stream. Such a curtain drain, bottomed-out in the glacial till would out off nearly all runoff from the hill. That would prevent worsening of your drainage problems, and probably would reduce them. It won' t entirely eliminate them because water south of would still infiltrate to the foreset beds of the delta in the area the subdivision road. However, that area is only a small part of the drainage area north of Dunphy Drive that now dumps water into the delta. I would encourage you to try to convince city officials of the benefits of such a drain. There are other steps for reducing surface runoff that could be used, but they probably would not be necessary if These additional steps would include tying all footing drains to the storm drain in the street, guttering all roofs and draining the gutters underground to the storm drain in the street, and installing curbs on driveways that are graded to drain into the storm sewers in the street. Lawns and yard areas are the remaining sources of increased runoff, and tney are the most diffi- cult to deal with, although numerous landscaping and drainage techniques exist for collecting that runoff and putting it into the storm drains. Whatever is done to deal with the increased runoff, everyone involved, including city officials, should be aware that after development is completed the rate of runoff is going to be much faster that it is at present. That increased rate of runoff will make the small perennial stream that picks up all of that drainage susceptible to flash flooding. The use of a curtain on the delta would dry out much of the a curtain drain is installed. dra n beneath the subdivision roads top part of the delta. That would allow some of trate the upper part of the delta, and introduce the water reached the curtain drain. This would the rapid runoff to infil- a runoff delay time before be beneficial in that it 8 would reduce the peaks of runoff and spread them out over a period of days. That would reduce stream. the possibility of flash flooding in the small perennial Submitted July 14, 1986 Thomas E.

July 11, 1986 Toi Mayor David Musante Planning Board, City of Northampton As a 10-yeas resident of Dunphy Drive and abutter to the proposed Maple Ridge project, we have some serious concerns that need to be addressed prior to any development. Mainly, the impact of thirty-one septic tanks and homes on our already overburned area. We suffer greatly with flooded basements, malfunctioning septic systems, high water tables and poorly draining surface water. After walking the area with Professor Tom Rice, hydrogeologist, we now know the cause -- glacial till that encourages horizontal flow of water on a down- grade slope (see enclosed letter). Since Dunphy Drive is approximately 260-280 £t. above sea level and Maple Ridge ranges from 280-410 ft. , gravity will prevail. The enclosed bill reflects only partial cost of flooding repairs. Dave Hawthorne, Pres. Misterka, Inc. , stopped billing us and routinely pumped our septic system, daily, during April and May of 1983. In the spring of 1984, an additional curtain drain was installed (free of charge) because the Oct. 1983 drain was insufficient (see enclosed photo). Landscaping and regrading fees sent another $1600.00 to Twin Cedars Nursery in Williamsburg. The regrading was not completed until summer 1985. At that same time, Crolle and Balise Plumbing installed a basement sump pump for approximately $400.00 because of ankle-deep water, AGAIN. There must be protection and guarantees for existing homes before further construction can be considered. As for traffic concerns, the addition of 30 new homes, 30 new children (minimum), at least 30 more cars traveling over Dunphy Drive to reach the proposed access road (Spruce Hill) will further endanger our area. Presently, we lack sidewalks and a stop sign at the junction of Dunphy Drive and Route 66. We have a blind corner mid-way up Dunphy Drive, an extremely hazardous intersection at Florence Road and Route 66, not to men- tion the nightmare of Jeremy Connors' accident. As a personal note, I (Kathleen) sat with him and my neighbor in the middle of Rt. 66 waiting for the ambulance. I never want to go through that again. Safety pro- visions for our children have to be made, especially, concerning school buses. The pick-up and drop-off spots, now, are Dunphy Drive and Rt. 66 (Jr. High and Smith), corner of Dunphy Drive and Spruce Hill for grade school (K-6). See enclosed editorial as to the traffic conditions on Rt. 66. The aforementioned were just some of our concerns. We hope that you folks on the Planning Board will take these into consideration while review- ing any requests for variances or special permits that would lower the minimum standards. Common sense and common decency should protect the homes and properties already in existence before consi»ring new housing. 9Cy , Kathleen and Charles Pysz OC n,...ru... nr,..e unr+h„mn+rn , 0 :e.,...,)0:-"`„;,'s •;:,44,1v.rit,Il‘f-0; r. 0+44 ' a „,t,rss'a • /II .V.41, f la its- , - ' , "r Aft& i s -,, „ r.:1,* tr.,s• arri:I5L; I, i . irili r ' sf‘ f Ff‘I' .v•r- „tin-- ' , ••"41 - •":„rr:, , .

Even careful drivers know that an unseen pedestrian or a passing bi- cyclist can be killed or have the rest of their life changed by a disabling injury, all within a few moments of inattention or carelessness by either party. We tend to keep that fear sup- pressed. but when we read of yet another accident, yet another vic- tim, the concern returns. Who has not been shaken by the realization that had we not braked fast enough or turned the wheel soon enough we, too, would be finding our names in the newspaper and then spending the rest of our own lives living with the reality that we have permanent- ly injured or killed someone? Sometimes, however, we as a society do not do enough to prevent the possibility of such tragedies, a fact reaffirmed by the report of yet another serious accident on the Westhampton Road stretch of Route 66 on Friday'evening. An II-year-old bicyclist is under intensive hospital care as a result, and as he suffers, his family and the motorist and her family suffer, too. One cannot be omniscient and say that more signs or traffic signals or police patrols or road redesign work would have prevented this latest tragedy. But surely anyone who knows anything about either the Westhampton or Rocky Hill road segments of Route 66 knows there are too many places along that road that are not engineered or marked to fully protect drivers,bicyclists or pedestrians. The accident logs have document- ed the tale There are several inter- sections there where those who know the road well travel it with extreme caution. Surely, many of those who are unfamiliar with the road are lulled into believing that it remains a country lane when, in fact, it has become the main road for the hundreds who have now built or bought homes along its many twists and turns and its occasional straightaways. The mayor and the City Council's police committee ought to give Route 66 some special attention; the people who live along it and those who only travel it to get somewhere else deserve some additional safety measures.
