Request for Proposals Engineering Services for the

Dredging of Center Springs Pond I. INTRODUCTION The Town of Manchester is soliciting proposals from qualified consulting engineering firms to provide engineering design services for the preparation of complete engineering drawings, specifications, cost estimates, environmental documents and related services outlined herein for a project to dredge approximately 15,000 cubic yards of sediment from Center Springs Pond.

II. BACKGROUND Bigelow Brook is a major east-west running watercourse in the Town of Manchester. The brook flows through Center Springs Park into Center Springs Pond where water is impounded by a vertical concrete wall at the western edge of the pond and released by a control valve to a series of culverts which flow beneath Edgerton Street and an abandoned railroad embankment before discharging to an open channel easterly of Broad Street. The watershed area to the pond is approximately 1,100 acres. Center Springs Pond is located within Center Springs Park, an urban recreation area in the midst of several rehabilitation projects. Part of the Town’s desire to enhance this park includes improving the water quality in the pond, which exhibits algae outbreaks during the summer months. The Town contracted with Dr. Ken Wagner of Water Resource Services Inc. in 2014 to assess various options to improve the water quality. Dr. Wagner’s assessment concluded that dredging the pond would be the most effective. Earlier this year, the Town contracted with Weston & Sampson to collect bathymetric data and perform soft sediment sampling to quantify the amount of material to be dredged and to identify the best approach. It was determined that approximately 15,000 cubic yards of material should be dredged from the pond. III. SCOPE OF WORK The general scope of this project includes the following: Preliminary Design 1. Attend kickoff meeting with Town staff to discuss project approach and schedule.

2. Assemble base mapping required for design of proposed improvements using existing GIS

mapping and bathymetric mapping provided by the Town supplemented with utility mapping provided by utility companies and regulatory limits as shown on FEMA mapping and the Town of Manchester Wetlands Map. Field survey location and wetlands delineation is not anticipated for this project.

3. Prepare preliminary design plans showing dredging method and limits, dewatering areas and erosion and sedimentation control devices.

Environmental Permitting 4. Contact regulatory agencies to identify and verify all required environmental permits needed

based on the scope of work. It is expected that the project will require a Section 404 Permit from the U.S. Army Corps of Engineers, a Section 401 Water Quality Certification and a General Permit for Water Resource Construction Activities from the Connecticut Department of Energy and Environmental Protection, and an Inland Wetland and Watercourses Permit, Floodplain Permit and Erosion and Sedimentation Control Permit from the Town of Manchester Planning and Zoning Commission.

3

5. Prepare necessary permit applications and supporting documentation for submittal to U.S.

Army Corps of Engineers, Connecticut Department of Energy and Environmental Protection and the Town of Manchester Planning and Zoning Commission. Provide draft applications to the Town for review and comment. Application fees will be paid directly by the Town.

6. Revise permit applications as required based on comments received during the permit review. 7. Attend one pre-application meeting with Town staff, one meeting with the Town’s

Conservation Commission, and up to two (2) meetings of the Town of Manchester Planning and Zoning Commission to present the project for approval.

Construction Documents 8. Prepare final contract plans, details, technical specifications and cost estimate. The Town will

furnish front end specifications for inclusion in bid package. 9. Prepare an estimated construction schedule for determination of contract time. 10. Deliverables include one final mylar, signed and sealed by the professional engineer in charge.

Introduction and Background

Center Springs Park is a recreational resource for the Town of Manchester, Connecticut, locatedbetween Main Street (Rt 83) and Broad Street, slightly north of Center Street (Figure 1). CenterSprings Pond is the focal point of the park, a 6.1 acre, manmade water body constructed from alow marshy area fed by Bigelow Brook. Spring through fall activities have included walking,picnicking and fishing, while winter activities include sledding. Until the late 1990s two skatingand ice hockey areas were maintained in small basins separate from the stream and pond, butthese have been made obsolete by indoor rinks. The Parks and Recreation Department mainoffice is located in the park, overlooking the pond.

The park and the pond were the subject of a 1991-1992 diagnostic/feasibility study by BaystateEnvironmental Consultants of East Longmeadow, Massachusetts. Much of what was learned inthat study (BEC 1993) remains valid today, over two decades later. In particular, Center SpringsPond receives runoff from a 1.5 square mile urban drainage area (cover photo), bringing with it arange of contaminants including sediment, bacteria, nutrients, metals, hydrocarbons and a varietyof trash items. Background flows are low at about 1.1 cfs, but storm flows can exceed 100 cfs,causing flooding in the park.

The current water level of the pond was set in the 1920s with the erection of an outlet structure,but infilling over the years was substantial. Both coarse and fine materials, both inorganic andorganic, filled the pond to a substantial degree. In 1993 the average depth of the pond was 4.7feet, with a maximum of 10 feet observed near the dam. The BEC study recommended dredgingand a variety of structural and maintenance activities in the watershed to reduce future sedimentand trash inputs, but it was acknowledged the water quality problems would be an ongoingproblem in light of watershed features. Dredging was completed in 1995 and a trash rack wasplaced slightly upstream of the pond within the park to catch debris. Dedicated personnel on theParks and Recreation staff cleaned the trash rack regularly at one time, but clogging and erosioneventually forced removal of the trash rack. A sediment trapping forebay was constructed at thepoint of entry of Bigelow Brook to Center Springs Pond, and has trapped coarse solids very wellfor almost 20 years; it is cleaned every few years as warranted.

A promenade was constructed on top of the berm that separates the sedimentation forebay fromthe pond, providing handicapped access and facilitating fishing and a more complete water view.Plantings in the park have increased sledding safety and the overall visual effect. The primaryissue has remained the unaesthetic appearance of the pond during summer. Algae, floatingplants, and rooted submerged plants have created unsightly and malodorous conditions at times,and interfere with fishing. A secondary issue has been access, as the park is bordered byresidential streets with limited parking and parking space in the park itself is also limited.

Manchester recently acquired a parcel along Broad Street that allows creation of a new parkaccess point, with more adequate parking and entry under a historic railway, coming from thewest and bringing park users to the outlet of Center Springs Pond. Issues with the outlet pipe,known from the time of the dredging in the mid-1990s, are being addressed as part of the newentryway construction. There is also renewed interest in improving the pond as a more usefulpark amenity. This investigation and management evaluation is intended to advance that effort.

Project Approach

Water Resource Services, Inc. was asked to assist Weston & Sampson with the pond andwatershed evaluation. Dr. Kenneth Wagner of WRS worked on the original pond study as part ofthe BEC organization and is familiar with the dredging project. Dr. Wagner met with ScottSprague, the long-serving Director of Parks and Recreation, who has been involved with parkoperation and improvements for over 25 years, including the most recent entryway development.They toured the park, discussed current issues, and viewed the plans for the new entryway. Dr.Wagner spent a day in the park, on the pond, and in the watershed, evaluating conditions andcomparing issues to those of 20 years ago.

In-lake activities included assessment of algae, plants and field water quality, along with probingthe pond bottom. Center Springs Pond was drawn down approximately 5 feet while the newoutlet pipe is being installed, so considerable peripheral area was exposed. Most usefulinformation was gathered by simple observation. Familiarity with past assessment of the pondand the dredging project aided investigative efficiency, and Mr. Sprague’s insights were mosthelpful.

Results

Watershed features are very similar to those encountered 20 years ago. Bigelow Brook drains anurbanized watershed of mostly residential area, but with a school, cemetery and somecommercial areas as well. Impervious surfaces represent a large portion of the watershed, suchthat runoff generation is high and storm flows are large relative to the size of the brook. Floodingis a very real threat to property, and the storm water drainage system is designed to get as muchwater into Bigelow Brook and out of the residential area as fast as possible. The result is elevatedflow with very little attenuation of volume or contaminants as it enters the park.

No water samples were collected during this investigation from storm water sources. Dryweather flows were observed and were low, as expected, but it is known from past experiencethat storm flows can be damaging. The stream is channelized, and in the park has steepembankments at least 3 feet high and very little meander. Water still overtops the stream banksin larger storms, as evidenced by debris and erosion outside the stream channel. The final stormbefore the trash rack was removed 3-4 years ago caused enough erosion after the rack clogged towarrant a restoration effort; the area has been filled and replanted.

Moving through the park from the eastern end where Bigelow Brook enters, the stream hasreinforced banks (concrete or rock) and a gravel/cobble bottom (Figure 2A). The former skatingareas run in parallel to the stream and are now unmanaged wetland areas (Figure 2B). BigelowBrook runs beside the former skating areas and passes under a bridge (Figure 2C) during low tomoderate flows; high flows have been known to exceed the height of the bridge decking. Thestream then traverses a long straight stretch with steep grassy banks bordered by grassy lawn(Figure 2D) until it reaches a buried culvert that leads to the sedimentation forebay (Figure 3A).The downstream side of the forebay is a berm upon which a wooden promenade has been placed,with a spillway at the southern (far) end (Figure 3B). The pond itself covers about 6 acres whenfull, but was lowered about 5 feet during the site visit (Figure 3C) for outlet construction. Theoutlet structure (Figure 3D) has both a subsurface drain and an overflow chamber.

The exposed periphery of the pond has some soft sediment (Figure 4A) and evidence offilamentous green algae mats (Figure 4B) that have dried upon exposure but are the source ofmany complaints when the pond is full. Aquatic smartweed (Polygonum amphibium) coveredmuch of the exposed area; this species is largely aquatic but can survive on pond banks as well.This plant has not been a dominant species in the pond when full in the past. Downed trees onthe wooded south side (Figures 4C and 4D) have been left as habitat, and are not visible with thepond full. Probing of the pond bottom revealed soft sediment averaging 1 foot deep in the upperthird of the pond, 2 feet deep in the middle area, and 3 feet deep at the outlet end. Coarsesediment is being trapped in the forebay, but finer sediments are moving into the pond andgradually refilling it.

Field water quality consisted of features that can be measured with instruments in the field,including temperature, dissolved oxygen, conductivity, pH, oxidation/reduction potential, andturbidity (Table 1). Values were elevated and similar to what was observed in the 1991-1992study, indicative of urban runoff impacts and elevated productivity in the pond itself. This doesnot preclude having an aesthetic pond that supports desirable fish and wildlife, but indicates thatthere will challenges to meet and obstacles to be overcome in order to meet use goals.

Table 1. Field Water Quality on October 7, 2014

Plants observed in Center Springs Pond were exactly as observed in 1991-1992, with floatingmats of duckweed (Lemna minor) and watermeal (Wolffia columbiana) and submergent growthsof waterweed (Elodea canadensis) (Figure 5). Filamentous green algae clouds and mats wereabundant and were identified as Spirogyra under the microscope. This alga gives off a foul odorupon death and decay. Microscopic algae were not abundant, with two diatoms (Gomphonemaand Fragilaria) and a flagellate (Cryptomonas) encountered.

With the water level down and limited flushing in the weeks prior to the site visit, it would belogical to think that cyanobacteria could be dominant in Center Springs Pond, but a longstandingelevated nitrate level tends to depress cyanobacteria in favor of green algae. This may be littlecomfort for those seeing or smelling large green algae mats, but the high nitrogen level doesappear to prevent what could be more odorous or even toxic conditions. The duckweed andwatermeal are also indicators of high nitrate levels. Elevated levels of phosphorus tend to controlthe amount of algae and floating plants present, while the ratio of nitrogen to phosphorus tends todetermine the types of algae and floating plants present. Center Springs Pond has had a high N:Pratios for many years, and that appears to still be the case, based on observation of plants andalgae.

Park personnel report few problems with algae or floating plants since the dredging until just afew years ago. The elevated nitrate was found in the water inputs to the pond, and was not likelyaltered by dredging. But the incoming phosphorus is often in an unavailable form, and mustsettle in the pond and be processed before becoming available. It seems likely that the build-upof soft sediment, expected to be rich in phosphorus, since the 1995 dredging is the primarysource of available phosphorus, and has accumulated to a degree that allows floating plant andgreen algae mats to become nuisances again.

Fish were observed during the site visit, and included white suckers and small minnows inBigelow Brook and largemouth bass and bluegill sunfish in Center Springs Pond. Thisassemblage is the same as 20 years ago.

Management Implications

Center Springs Pond is a manmade water body in an urbanized watershed. It was recognized inthe thorough study of over 20 years ago that managing the pond for acceptable conditions wouldbe a maintenance effort, and nothing has happened to change that situation. Adequate preventionis not really practical in an urban watershed, despite the federal government emphasis onwatershed management. Urban runoff tends to increase nutrient levels about tenfold, whilerestorative management methods tend to reduce nutrient levels by about half; the net increasecreates productivity problems in receiving ponds without at least periodic maintenance activities.

The environmental agencies of Connecticut have been more rational in their approach, seeking tolimit watershed inputs but acknowledging the near futility of trying to make urban runoff cleanenough to avoid problems in receiving lakes. Past management of Center Springs Pond has beenconducted with practical limitations in mind, but not enough maintenance has been conducted toretain desirable conditions indefinitely.

Page 9

Dredging was necessary to restore lost depth and remove sediment that was supporting denseplant growths and algae mats, and improved Center Springs Pond for about 15 years. Similarresults have been obtained in other urban park ponds. Removal of the soft sediment base greatlyminimizes mat forming algae and aquatic plants until the sediment is replaced. Formation of asedimentation forebay has limited infilling with coarse sediment, but fine sediment has passedthrough the forebay and settled in the pond. Enough of the capacity gained by dredging in 1995has been lost to warrant considering dredging again, but there are other options to be consideredas well.

Pond management can be divided into four general areas: prevention of problems, rapid responseto invasions or contamination, restoration from damage over time, and maintenance of conditionsin the face of continuing impact. Prevention is always desirable, but in an urban watershed thereare definite limits on what can be done short of buying property and converting it to uses thatcontribute fewer pollutants. The time for rapid response has long passed. Restoration wasattempted through dredging, and some success was achieved, but the continued input of sedimentand related contaminants has put Center Springs Pond back into a less desirable condition.Restoration could again be applied, but some form of maintenance activity is also needed.

There appears to be recognition of the need for maintenance in Manchester, and while morepermanent improvements are desirable, the cost and limited duration of benefits suggest thatmaintenance activities would be included in any major program this time. Further discussion ofneeds and options is advisable, but a technically feasible approach can be suggested here.

Management Options

Means for controlling algae and floating aquatic plants that get their nutrition from the watercolumn or surface of the sediment are plentiful, but not all will be applicable or feasible (Table2). Methods with high applicability include watershed management, dredging, and phosphorusinactivation. Approaches with moderate applicability include settling agents, algaecides,sonication and microbiological augmentation.

Watershed management of any kind would improve water quality in Center Springs Pond, andthere are undoubtedly things that could be done for low cost, including homeowner educationand routine catch basin cleaning. Phosphorus is being voluntarily removed from most lawnfertilizers by the manufacturers, so improved water quality should be evident over the nextdecade. However, no simple or affordable measures are available that will provide the level ofimprovement needed on a regular basis; the magnitude of loading from this watershed is simplytoo great.

Yet there is an opportunity to improve the quality of some of the water that enters the pond thatwould allow this improved water to be added after the flushing by the main body of the storm iscomplete. The former skating ponds (Figures 2B and 6), now almost empty and adjacent to thestream, could be used as detention areas for first flush storm water, usually of the poorest quality.Water detained or even treated in these basins could be discharged at the end of the storm toimprove water quality in the pond. The ponds would need some modification to function atmaximum effectiveness, but could be used as is with just the addition of a diversion point in thestream.

to pollutant trapping. Withe processed through theseond could be acceptable at

Page 22

A detention/treatment system involving the former skating ponds would be within the park andmore easily managed than diffuse efforts in the watershed. Such systems are fairly common inFlorida, where the difficulty of managing urban storm water has been recognized and alternativeapproaches to maintaining lake water quality have been sought. A capital cost approaching$200,000 is anticipated, including a dosing station for treating storm water, and the operatingcost will depend on the weather and storm water volume treated. Assuming that water equatingto about five pond volumes was treated each year, the annual operation cost would be on theorder of $10,000 to $15,000.

As an alternative, aluminum or another coagulant could be dosed into the forebay, probably intothe stream just upstream of the culvert, allowing mixing to occur in the culvert with particlesettling in the forebay. This would improve solids retention in the forebay and lower phosphoruslevels entering the pond. It may be necessary to alter the outlet arrangement from the forebayfrom submerged pipes with an overflow weir to the pipes having their intakes near the surface orthe weir becoming the primary exit point. Calculation of the detention time of the forebay overthe range of flows experienced should be performed, but under most circumstances most solidsshould be retained. Where coagulated solids do pass through the forebay, the associatedphosphorus should be largely inactivated and not fuel algal mats.

An inactivation system associated with the forebay would require less effort than one in theformer skating ponds, and could be made more secure in association with the park building nearthat site. A chemical tank and metering pump with controls could feed coagulant via anunderground line to the stream just upstream of the culvert leading to the forebay for about$50,000. Enhanced mixing with compressed air would raise the cost by about $30,000, but maybe unnecessary. Some baffling within or just upstream of the culvert in the stream should besufficient to mix the coagulant with the storm water at minimal cost. Operation costs would besimilar to those projected for the former skating ponds site ($10,000 - $15,000). One additionthat would be desirable would be an automated control system that would turn the system on inresponse to precipitation or increased flow; a cost of about $25,000 would be anticipated.

Treatment of the pond directly is also an option, with a dosing distribution system that includes amixing function. This would be turned on after storms to clear the water in the pond andinactivate phosphorus that has entered it. While accumulation of solids in the pond wouldincrease under such a scenario, it would not be much more than currently experienced. However,as the pond has experienced substantial infilling since dredging about 20 years ago, capturingmore solids in the forebay would seem preferable, especially if dredging is repeated. An in-pondtreatment system would be more expensive than the forebay option, mainly owing to moredistribution tubing and the need for an active mixing system (usually compressed air). A cost ofabout $150,000 is envisioned. Operational costs would be proportional to use; more chemicalwould probably be used and more power would be needed to run the mixing system, suggestingan annual operational cost of $20,000 to $25,000.

As an alternative to a dosing station to directly address the pond, periodic treatment by boat toinactivate phosphorus in the water and surficial sediment would limit growth of algae, but theduration of effectiveness is uncertain. The dose needed is also uncertain at this point, butassuming a dose of 50 g/m2 (about the average for such treatments in New England) over 5 acresof pond, a treatment would cost about $15,000. Unless storm water is also treated, the benefits

Page 23

may only last a short time, but algal mat formation might be prevented for the summer seasonwith a single late spring treatment. Rooted plant growth would be largely unaffected. If anything,clearer water may increase plant growth.

Dredging was performed in 1994 – 1995 and improved conditions to some extent for about 15years, despite continued urban runoff dominance. Repeated dredging would be expected toprovide similar benefits, although failure to address runoff inputs will limit success and durationof benefits. Soft sediment currently in Center Springs Pond is estimated at about 16,000 cubicyards. Removal would be expected to cost on the order of $500,000 at today’s rates. This is adesirable but expensive option.

Estimation of dredging cost is a highly site specific effort, and should be conducted by anexperienced engineering firm that considers sediment quantity and quality, physical removalmethods, disposal options, and restoration of peripheral sites and any containment area. We donot have recent sediment quality data and the estimation of sediment quantity is based on limitedprobing, but there is no reason to believe that the project would be appreciably different than theone conducted 20 years ago. Representatives of the Town of Manchester have suggested thatdisposal in an existing town landfill would be possible, limiting disposal costs. Costs have risenin 20 years, but the process would likely be the same, with water routed around the side of thepond in a channel and sediment removal conducted with conventional equipment under “dry”conditions.

The original cost estimate provided by BEC in 1992 was $403,450, but this included forebayconstruction and the fishing pier, among other improvements, and actual dredging cost wasestimated at about $300,000 for up to 21,500 cubic yards, or about $14/cy, exclusive of designand permitting costs. The range of costs encountered in recent dredging projects have rangedfrom $30 to $100 per cubic yard, all inclusive, with position along that range largely determinedby sediment quality and disposal requirements, which have assumed increased importance overthe last two decades. Assuming that the town landfill can accommodate the current sediment inCenter Springs Pond, a cost near the low end of the recent range would be expected. This leadsto a very rough estimate of $480,000, rounded up to $500,000 above. A cost in excess of $40/cywould not be expected, suggesting a cost of $640,000 as a maximum.

To further the dredging option, sediment quantity and quality need to be more preciselyevaluated. Mapping and calculation of sediment quantity will cost about $5000. Sediment qualityis now assessed with one sample per 1000 cy removed, so for the currently estimated 16,000 cywe would need to collect 16 samples at a cost of about $3000 and analyze them at a cost of about$16,000 ($1000 per sample), or $19,000. Adding consideration of dredging and disposal options,a dredging feasibility assessment that more precisely estimates costs and serves as the basis fordesign and permitting could be produced for $30,000.

Other options for pond improvement with more moderate applicability include settling agents,algaecides, sonication and microbiological treatments. Settling agents would include thealuminum treatments previously described, but could include alternative coagulants that wouldmostly settle solids and might be less effective at making phosphorus unavailable. At similar costto aluminum coagulants, settling agents would be much less favored.

Page 24

Algaecides include mainly copper and peroxide compounds, neither of which is very effectiveagainst filamentous green mats. A relatively new herbicide with the active ingredientflumioxazin has shown promise for control of algal mats and could be tried. If a single treatmentper year would suffice, this could be an affordable option at about $5000 per treatment.

Sonication is also a relatively new technique, but is based on laboratory procedures that break upalgal clumps for analysis and is applicable to field situations. Sound waves of a specificfrequency range have been found to damage algae cells, although not all algae are susceptible.The method requires direct exposure to the sound waves; rocks, plants or other obstructionsminimize impact. Consequently, multiple units may be necessary to cover an area like CenterSprings Pond and some form of plant control may be needed. Also, green algae mats are fairlyresistant once formed, so the units would need to operate all the time and be focused on most ofthe pond bottom. Units cost $3000 to $5000 each, and as many as 6 units might be needed inCenter Springs Pond, but once in place the only operational costs are power and maintenance(i.e, keeping units clean). It is not clear that sonication will solve the algae problem in CenterSprings Pond, but a unit might be tested in a target area as an experiment.

Microbiological treatments are difficult to evaluate, as there is virtually no peer reviewedliterature. The theory is that additives that help break down organic compounds or stimulatebacterial activity, possibly along with engineered bacteria, can digest organic sediment andminimize algae growths. The exact mechanisms are not well explained, but in most cases thetreatment is coupled with some form of oxygenation, as oxygen is needed for bacterialrespiration. Documented successes do exist, but there are also many failures and no publishedevaluation of this group of techniques. Some experimentation may be warranted, but it cannot beconsidered a front line technique at this time.

The above management options do not consider rooted plant issues in Center Springs Pond. Thefloating plants duckweed and watermeal behave more like algae, taking their nutrition from thewater column. The dominant rooted plant in Center Springs Pond is waterweed, which has notbeen mentioned as a problem, and may in fact not be an issue for management at this time. But ifthere are concerns over waterweed density, an entirely different list of rooted plant managementoptions would need to be considered. Dredging and herbicides are on that list, but no otheroptions discussed here would be applicable.

Summary

Center Springs Pond is a valued resource and the centerpiece of the associated park. It sufferswater quality impairment as a consequence of its largely urbanized watershed, and no reasonableamount of watershed management can be expected to improve pond condition to the desiredlevel. The condition of the pond will become even more important with park accessimprovements now underway, and the Town of Manchester is looking into best managementpractices for maintaining Center Springs Pond.

A short survey in October of 2014 found water quality influences similar to those encountered inthe early 1990s; storm water runoff is the main contributor of nutrients, sediment and othercontaminants to the pond, considerable soft sediment has built up in the pond since dredgingabout 20 years ago, and pond biology is nearly identical to that encountered two decades ago.Dredging improved conditions for about 15 years, and continued management of the forebay

Page 25

installed in association with the dredging has limited coarse sediment accumulation in the pond,but restoration and/or maintenance actions are again needed to enhance pond condition.

Review of options narrowed the preferred approach to repeated dredging with enhancedcoagulation of incoming storm water. If dredging is not conducted, direct treatment of thesediment to inactivate phosphorus that fuels algal mat development would be desirable, and mayneed to be repeated at least annually at a cost on the order of $15,000 per treatment. If dredgingis conducted, benefits can be prolonged by installation of a dosing station for coagulants thatfocuses on phosphorus but also removes many other contaminants. A system could be installedin association with the former skating ponds, the forebay, or in the pond itself. The leastexpensive but effective option, estimated at about $75,000 capital cost and $15,000 annualoperating cost, would involve automated metering of an aluminum compound into the streamjust upstream of the culvert leading to the forebay.

Proper evaluation of dredging options and costs would be part of a feasibility assessment focusedon sediment quantity and quality at an estimated cost of $30,000. However, based on thedredging conducted 20 years ago, indication of available landfill capacity by the town, and recentdredging projects, a total cost on the order of $500,000 to $640,000 for removal of 16,000 cubicyards is currently envisioned. The dredging feasibility assessment is critical to verifyingassumptions made in this preliminary estimate and refining it to the point where design andbidding can proceed.

Even if dredging and enhanced coagulation in the forebay are implemented, actions upstream ofthe pond are warranted to protect the investment. Watershed management is always appropriate,but will not be sufficient by itself to protect the pond; the urban nature of the watershed is notamenable to adequate water quality improvement through available best management practices.Conversion of the former skating ponds into detention basins to hold first flush water, with orwithout enhanced coagulation, has potential to greatly improve incoming water quality, althoughthe potential capacity of those ponds requires additional evaluation.

Re: Summary of Results - Center Springs Pond, Manchester, CT

Dear Mr. LaMalva:

This letter report serves to summarize fieldwork and results related to providing you with an initial costestimate for dredging Center Springs Pond. The work involved (1) measuring pond depth and sedimentthickness; (2) obtaining and analyzing three composite sediment samples; (3) estimating the thicknessof soft sediment and (4) developing an initial cost estimate.

WORK PERFORMED

An initial reconnaissance noted a continuous band of mature forest along the southern edge ofthe pond; the northern edge is partially grassed and sloping. Some algal mats were noted alongwith aquatic vegetation in the pond.

Actual field measurements and sampling was carried out by a two-person crew utilizing a Park& Recreation Department boat. Bathymetric data was measured utilizing a graduated staff. AGPS Trimble Unit (GeoXH) was used to locate each point. The staff was hand driven throughthe sediment layer until refusal with GPS recordings taken at the top of soft sediment and at thedepth of refusal.

Three (3) soft sediment samples were obtained by hand auger, then composited. The sampleswere transported to Con-Test Analytical Laboratory (East Longmeadow, MA) for analysis.

The Connecticut Department of Energy and Environmental Protection’s (CTDEEP) on-lineNatural Diversity Database (December 2014) map was reviewed for an initial screening of Stateand Federal Listed Species and Significant Natural Communities. Center Springs Pond is notwithin or near an area identified as potentially sensitive.

CTDEEP’s on-line Water Classification Map (August 2014) was reviewed. Center Springs Pondis assigned Class A Surface Water and Class GB for groundwater.

The Federal Emergency Management Agency’s on-line FIRM mapping was utilized to identifyfloodway areas and special flood hazard areas.

GPS data points and field data were inputted in AutoCad to depict bathymetric and softsediment measurements.

Measured soft sediment volume, as calculated using AutoCad, is 11,920 cubic yards.

The results of the sediment analyses were evaluated by Weston & Sampson LicensedEnvironmental Professionals and compared against the Connecticut Department of Energy andEnvironmental Protection’s Remediation Standard Regulations (RSRs) and the Town ofManchester’s Landfill Waste Characterization Parameters and Acceptance Limits. The resultsindicate elevated levels of certain semi-volatile organic compounds, with an exceedance ofCTDEEP’s Industrial/Commercial Direct Exposure Criteria and GB Pollution Mobility Criteria andthe Town’s landfill acceptance limits for Benzo(a)pyrene.

Several dredging/excavation contractors were contacted. Many requested that a site visit beconducted and inquired about whether the project would be bid or would the Town requestsimply cost estimates.

Natural Diversity Data Base

December 2014

Areas

NOTE: This map shows general locationsof State and Federal Listed Species and

Significant Natural Communities. Informationon listed species is collected and compiledby the Natural Diversity Data Base (NDDB)

from a number of data sources . Exact locations of species have been buffered to produce the general locations. Exact locations

of species and communities occur somewhere in the shaded areas, not necessarily in the center. A new mapping format is being employed

that more accurately models important riparian and aquatic areas and eliminates the need for the upstream/downstream searches required

in previous versions.

This map is intended for use as a

preliminary screening tool for conducting aNatural Diversity Data Base Review Request.To use the map, locate the project boundaries

and any additional affected areas. If theproject is within a shaded area there may be a potential conflict with a listed species. For

more information, complete a Request for Natural Diversity Data Base State Listed Species Review form (DEP-APP-007), and

submit it to the NDDB along with the required maps and information. More detailed instructions are provided with

the request form on our website.

www.ct.gov/deep/nddbrequest

Use the CTECO Interactive Map Viewersat www.cteco.uconn.edu to more precisely

search for and locate a site and to view aerial imagery with NDDB Areas.

SW-846 8270D

The LCS sample recoveries for required RCP 8270 compounds were all within control limits specified by the method, 40-140% for base/neutrals and 30-130% for acids except

for �difficult analytes� listed below and/or otherwise listed in this narrative: Difficult analytes for soil - limits between 10 and 180% depending on the compound (see QC

summary for limits): 3,3�-Dichlorobenzidine, Pyridine, Aniline, 4-Chloroaniline, 3-Nitroaniline, and n-Nitrosodiphenylamine.

All reporting limits specified on the chain-of-custody were met, except for Pyridine, 1,2,4,5-Tetrachlorobenzene and Pentachloronitrobenzene for the most protective criteria since

the laboratory cannot achieve the required RCP calibration criteria at these levels unless otherwise listed in this narrative .

The results of analyses reported only relate to samples submitted to the Con-Test Analytical Laboratory for testing.

I certify that the analyses listed above, unless specifically listed as subcontracted, if any, were performed under my direction according to the approved methodologies listed

in this document, and that based upon my inquiry of those individuals immediately responsible for obtaining the information, the material contained in this report is, to the

best of my knowledge and belief, accurate and complete.
