SURVEYORS ENGINEERS - LANDSCAPE ARCHITECTS INTRODUCTION The Stop & Shop Companies are the owners of a shopping center on the westerly side of King Street, Northampton, Mass., known as "Kingsgate Plaza". Anchor stores are a Stop & Shop supermarket, a Bradlees Department Store, and a Serve-U store, along with several satelite stores. To provide the latest in public convenience in shopping, Stop & Shop Companies have developed what is called a "Super Stop & Shop". These new super Stop & Shop stores not only offer basic foot items, grocery, meat, produce, self service deli, and dairy, but also specialty departments, such as service, cheese, salad bars, melon bar, fresh pasta, service fish, service bakery, soup to go, flowers, service delicatesson and bulk foods. They also include wide assortments of general merchandise. The site that Stop & Shop wishes to construct their new store lies immediately to the North of the present Kingsgate Plaza and contains a total of 15.907 Acres. The site comprises of two parcels of land; 13.946 Acres owned by the Graves Realty Company and 1.961 Acres owned by the 246 King Street Realty Trust: Stop & Shop Companies have a purchase option on each of the properties, providing they can be developed as proposed. The location of the proposed project is shown on Exhibit 1. The existing Kingsgate complex is shown as "A" and the proposed project is denoted as "B". Access to the proposed complex will be through the existing Kingsgate complex and by an access road running northerly to Barrett.Street, as shown on Exhibit 1. Stop & Shop Companies filed a Notice of Intent with the Northampton Conservation Commission and a public hearing was held on January 30, 1984. A second public hearing to further discuss the project was held on March 19, 1984. See Exhibit 10. After discussions at that public hearing, Stop & Shop Companies requested a continuance of that hearing, so that further information relating to the wetlands issues could be presented to the Commission. Almer Huntley, Jr., & Associates, Inc. has been retained by Stop & Shop Companies to prepare a report on the wetlands issues of the site and to present the report on July 9, 1984, to the Commission. Almer Huntley, Jr., & Associates, Inc. believes that the wetlands issues can be addressed in a sensible manner and that the project can be constructed without adverse effects on the environment. ALMER HUNTLEY, JR., & ASSOCIATES, INC. j SURVEYORS -ENGINEERS= LANDSCAPE KRCH1TECTS°-~ I Pg. 2 Portions of the proposed site and adjacent land contain growth commonly found in wetland areas necessitating a determination of applicability as an Inland Wetland, by definitions in the Wetlands Protection Act Regulations, effective April 1, 1983, adopted under MGL Chapter 131, Section 40. These j areas are delineated on Exhibit 2. There are no brooks or streams within the proposed site. Topographical surveys have been made of the proposed site and adjacent land bordering on the south owned by Stop & Shop Companies; on the west owned by the City of Northampton; and along the route of the King Street Brook from the box culvert under the old railroad. bed (formerly NY, NH, & H Railroad, Williamsburg Branch), hereinafter referred to as the "upper culvert", northerly to the box i culvert under the old railroad bed (formerly NY, NH, & H Railroad, Shelburne j Branch), hereinafter referred to as the lower culvert adjacent the Hampton Gardens Housing Complex. Topography of the proposed site ranges in elevation from E1. 141.3 MSL to E1. 152 MSL. The lower elevations tend to be located at the southerly and westerly sides of the property and the higher elevations at the easterly and northerly portions. The areas containing growth commonly found in wetland areas tend to be located below E1. 143 MSL. Refer to Exhibit 2 and Exhibit 9. - i The adjacent area to the south is the Kingsgate Plaza shopping center; the E i various abuttors to the east are automobile dealerships, an auto parts supplier, a heavy equipment sales and repair shop, and a home heating fuel oil storage and office. In part, land to the west is owned by the City of I Northampton and in part by private ownerships, and not developed. Two single family homes abut the project land at its northwest west corner on Barrett Street. The topographical surveys, examination of drainage piping, storm water culverts, records at the Hampshire County Registry of Deeds and at the City of Northampton Department of Public Works, and construction plans of the Kingsgate Plaza prove beyond any reason of doubt, that the areas containing growth commonly found in wetland areas on the project parcel have been man-made within the past twenty years. The site parcel has been used as farm land, growing hay~ and. agricultural crops over its entirety. Presently, due to the artificially I created wetlands, this cannot be accomplished. ALMER HUNTLEY, JR., & ASSOCIATES, INC. crTnvnvlwc _ FN(:TNFFRC _ i.ANTIR(`APF AR(`NTTF.('.TC Pg. 3 The mitigating factors which cause this problem are: 1. Lack of maintenance of the channel of King Street Brook and associated culverts. 2. The inadequately sized culvert that carries King Street Brook under Barrett Street. 3. The obstruction in the culvert under Barrett Street which reduces the available culvert flow capacity by almost fifty percent (50°x). 4. The lack of maintenance of the drainage outlet from the Stop & Shop parking lot into the King Street Brook. These items are inter-related and the resolution of one of the items will not solve the whole problem. They must be dealt with collectively to provide a solution to this problem. The balance of this report discusses the problems in depth and offers solutions to them that are reasonable. ALMER HUNTLEY, JR., & ASSOCIATES, INC. r KING STREET BROOK The King Street Brook, sometimes called Barrett Street Brook, is the collection point for a large drainage area of the City. The area of the watershed is approximately 425 acres, mostly residential with some commercial and industrial contribution. The watershed is shown on Exhibit 3. Until 1905, the King Street brook flowed easterly and parallel to the NYNH&H Railroad tracks and entered culverts on or near King Street. It has been claimed that this brook was used as a feeder stream for the New Haven - Northampton Canal. In 1905, because of the flooding problems caused by this brook, the City of Northampton entered into an agreement with the NYNH&H Railroad to install a culvert under the Williamsburg Branch of the railroad, the upper culvert. See Tl, M M r 7u At the same time, the City took in fee, a strip of land of varying width to construct a channel to convey the waters of the King Street Brook, northerly to the Connecticut River. See Exhibit 7A&7C. The intent of this action was to divert the King Street Brook so that it flowed northerly via the new culvert under the railroad and along the newly created channel to the Connecticut River. The brook is now enclosed until it flows into an open channel at a point a few hundred feet southwesterly of the upper culvert. The brook then flows under the old railroad bed through a 4'x4' concrete culvert. The flow continues in a northerly direction through land of the City (the westerly abuttor to the project site) to Barrett Street, where it flows under Barrett Street through a 24" culvert. The flow continues northerly to the lower culvert, where it enters a 4' wide by 5' high stone arch box culvert. After the brook passes under the old railroad bed via this lower culvert it immediately enters a 5' diameter RCP reinforced concrete pipe which flows under the Coca Cola Bottling Plant yard and building to join a 3 1/2' high x 4' wide reinforced concrete box culvert, which was constructed under the King Street - Bridge Road - Damon Road intersection. This culvert discharges a short distance northerly of the intersection of King Street and Damon-Road and flows via an open ditch and culverts under the B & M Railroad and Interstate 91 to its discharge at the Connecticut River approximately a thousand feet northerly of Damon Road. The routing is shown on Exhibit 4. ALMER HUNTLEY, JR., & ASSOCIATES, INC. Pg. 5 The topographical survey and field investigation of King Street Brook and its culverts have revealed that the gradient of the brook between the upper railroad culvert at the rear of the Kingsgate Plaza and the lower railroad culvert near the Hampton Gardens project is extremely flat. The overall horizontal distance between the two culverts is 2,675 feet, with a one foot drop in elevation, which creates a theoretical gradient of .000374. From the lower culvert under the old railroad bed at Hampton Gardens, the line drops 4.2 feet in approximtely 900 feet where it discharges into the ditch leading to the Connecticut River. There does not seem to be a problem in the drainage flow from the lower culvert to the Connecticut River. Exhibit 5 depicts the horizontal and vertical plan of the Brook between the two railroad culverts. The invert of the upper railroad culvert is E1. 139.8 MSL. The depth of the sediment in the culvert is 1.6 feet deep, making the elevation of the Brook channel El. 141.4 as it leaves the culvert. The sediment is the accumulation of many years of material settling out after being transported from upstream locations. Much of this material is sand from winter sanding of streets in the watershed. Approximately 1,700 feet downstream from the upper railroad culvert, the Brook reaches Barrett Street. As noted before, the culvert under Barrett Street is 24" in diameter, which is inadequate to take care of the King Street Brook flows. The invert of the upstream end of this culvert is E1. 139.8 MSL, while the theoretical Brook gradient at this point is 139.17, making the culvert invert .63 feet (7 3/4") higher than the stream gradient. Passing through the culvert is a 10" cast iron sanitary sewer pipe. The elevation at the top of this sewer pipe is E1. 140.70. The bottom of the sewer pipe is approximately elevation 139.7. This condition effectively places a barrier within the culvert and reduces the capacity of the culvert by almost 50%. The above described conditions are shown on Exhibit 6. At the lower railroad culvert invert, the Brook channel coincides with the invert of stone arch culvert. This condition is due to the flushing action of' the storm drainage discharge from the Hampton Gardens project and the improved gradient through the culvert to its point of discharge north of Damon Road. ALMER HUNTLEY, JR., & ASSOCIATES, INC. QTTnvFVnnc - RN(1TNFRRC - T.ANTIC(`.APR ARC'.HTTF.C'.TC Pg. 6 The channel of the brook between the three culverts is silted up to elevations as much as two feet above the theoretical gradient. The channel meanders to some degree and, in some places, can be difficult to find due to the growth of alders, willows, weeds and grasses. In many locations the channel is clogged with logs and rubbish. The entrance to the culvert at Barrett Street is clogged with wood, rubbish and shopping carts. As a result of the above described conditions, Barrett Street acts as a dam across the Brook and has caused a large area upstream to become a swamp or wet meadow. As noted hereinbefore, depending on the location under consideration, this has caused areas up to EL. 143 to become wetlands. The City of Northampton has maintained the channel of the Brook for many years. A portion of the Brook passes through land of the City, which was a part of the so-called "Poor Farm". This land was used for hay and crops. There was a "cattle pass" culvert under the Williamsburg branch of the old railroad bed to provide access to the fields from the farm buildings, which were located near where the B'Nai Israel Synagogue now is located. The Northampton Department of Public Works has attempted to secure funds for many years to dredge or otherwise improve the King Street Brook channel. However, funding constraints have not allowed the dredging and other improve- meets to be accomplished. In 1961, Stop & Shop Companies constructed the Kingsgate Plaza. The drainage from the parking lot and from roof drains was picked up by a drainage system and discharged into the King Street Brook. Exhibit 8 shows that drainage scheme in detail. We have field checked the drainage system and found that it was constructed closely in conformance with the plans. The parking lot drainage in front of the Bradlees store sheet flows to the north side of the lot and is picked up by a concrete channel with an iron grillwork covering it. The water flows along the channel and enters two 18" reinforced concrete culverts which run in a westerly direction under the northerly side of the parking area and beneath the driveway area between the Bradlees store and the property line. The culverts discharge into a second concrete channel covered by an iron grill. This covered channel picks up some drainage water from the parking area in the rear of the Bradlee store and discharges at a point about 30 feet easterly of the King Street Brook. The discharge is then supposed to flow via a ditch to the Brook. ALMER HUNTLEY, JR., & ASSOCIATES, INC SURVEYORS =ENGINEERS---LANDSCAPE-ARCHITECTS- Pg. 7 As the 18" RCP drainage lines pass through the area between the Bradlee store and the property line, two 10" drainage pipes were extended northerly to intercept and carry surface drainage from the abutting property on the north into this new drainage system. These connections were made because the construction of the Ringsgate Plaza required grading of the site in such a manner as to block the natural drainage of the abutting land to the north. The R.ingsgate Plaza plans show that the elevation of the Barrett Street Brook at the point of intersection with the ditch leading from the concrete channel was E1. 140.9. The invert of the concrete channel design grade was to be El. 141.2. Our investigation shows that the invert of the end of the concrete channel as it was constructed is El. 140.6.. The water elevation in the Brook where the channel is supposed to discharge is E1. 142.6. Invert of Channel - Design E1., 141.2 Invert of Channel - As-Built E1. 140.6 Water Elevation in Brook - 1961 E1. 140.9 Water Elevation in Brook - 7/2/84 El. 142.6 Ground Elevation between end of Concrete Channel and Brook 7/2/84 El. 143.0 Standing Water Elevation in Concrete Channel 7/2/84 El. 142.9 The drainage water cannot exit the concrete channel due to: a. the high ground elevation between the channel exit and the Brook; b. the elevation of the Brook has risen by 1.7 feet since 1961. The standing water in the channel is E1. 142.9. This water elevation is higher than the invert of the drains which were to carry the surface water from the property to the north. The inverts of these drains are 141.88 and 141.3 respectively. With the standing water in the drain at elevation 142.9, these lines are surcharged. Land to the north, cannot drain and remains flooded. During storms and other times of high runoff, it is our opinion that the storm water is discharged onto the land to the north, as it cannot exit through its designed outlet to the Brook. With the property to the north being continually flooded at or near E1. 143.0, certain areas that were formerly crop land now support a growth of willow, alder and wetland grasses.

ALMER HUNTLEY, JR., & ASSOCIATES, INC. PROPOSED SOLUTIONS After studying the drainage problem in the area, and the conclusions, the Stop & Shop Companies wish to propose the following solution so that they can proceed with their project. 1. Dredge King Street Brook: The King Street Brook would be dredged from the upstream end of the upper railroad culvert, including removal of the sediment in the culvert down to its invert, to the lower railroad culvert. The ditch would be constructed to a proper cross section and brought to its theoretical grade. 2. Barrett Street Culvert: A culvert of proper size would be constructed at Barrett Street. Because of the centerline elevation of Barrett Street, this culvert would be low head reinforced concrete design. 3. Relocate Sewer Line at Barrett Street: The sanitary sewer which crosses through the Barrett Street culvert and effectively blocks up the culvert will have to be replaced with a sanitary sewer siphon arrangement to pass the sewage under the proposed culvert. A preliminary review of the siphons criteria indicate this is a viable solution. 4. Create a Drainage Retention Area: The Stop & Shop Companies will create a drainage detention area on a portion of the land they wish to construct the new facility. The drainage from the parking and roof drains of the new facility will drain into this area, which will lie northwesterly of the proposed store and parking lot. Its. size and elevation will be designed to provide a detention for storm flows from the King Street Brook watershed as well. The Stop & Shop Companies are willing to fund the engineering design and the construction of the above items if they are allowed to proceed with their project. The City of Northampton would greatly benefit. The drainage problem on the King Street Brook would be taken care of, a new culvert and sewage line would be constructed at Barrett Street, and a storm water detention area would help ALMER HUNTLEY, JR., & ASSOCIATES, INC. ~`----"-'__----SURVEYORS"=-ENGINEERS= LAN-DSCAPE°ARCHITECTS - i Pg. 10 • 1. i i regulate the storm flows on King Street Brook, and there would be a large increase to the City's tax base and the providing of a large number of jobs to I City residents. The proposed stores and parking area that Stop & Shop wishes to construct are shown on Exhibit 9 as a plan and cross-section. The area will be cleared and grubbed and top soil removed. Gravel fill will i be brought in and compacted until the design grades are reached. In some areas, only 18" to 24" of fill will be brought in, while other areas, especially beneath the proposed stores, up to seven feet of fill will be needed. I The total area of filling will be approximately 7.5 acres. Of that total, 1.1 acres are "wetland" (El. 143 and lower), which has been artificially created. The proposed detention site would have an area of 1.95 Acres, and would more than compensate for the artifically created "wetlands" that would be filled by the project construction. .11 ALMER HUNTLEY, JR., & ASSOCIATES, INC. o Vl%~ vL Iva~ ~.r i IM ~ 1 J~ EXHIBIT 3 l r ~ i V 4"TT fto IT~•~ {f ` Y r 0 4VF.... 1 aT ARO~c ciim s" 4 r t a "CMaY4w alt \ ZD.

Gentlemen: AREA CODE 413 TEL. 584,0368 I represent Mr. Norman Graves who owns the land on which the Wetland petition has been filed by Stop & Shop. Mr. Graves has an agreement with Stop & Shop to sell this land at a substantial price assuming all necessary permits are granted. I was not able to be at the meeting on July 9th as I had a prior commitment in Boston. However, I have reviewed the plans and the facts which Almer Huntley developed. These facts appear to me to establish beyond much reasonable doubt, that at one point prior to 1905, the stream which presently flows behind Mr. Graves' land instead of running in a northerly direction at the rear of the present Stop & Shop complex ran east and southerly. By a taking recorded on July 12, 1905 in the Hampshire Registry of Deeds, Book 596, Page 375, the Sewer Commissioners of Northampton made a taking which read in part: "Whereas public health and convenience require the taking and diversion of the stream known as the King.Street Brook beginning on said stream about 654 feet above the mouth of the sewer on State Street, and in the rear of home lot of Mary Fitzpatrick, so that said stream as diverted shall empty into the Connecticut.River at a point near the northeasterly corner of land of Minnie E. Mason * * and said stream is hearby taken in order to be diverted in accordance with the following layout". TO: Northampton Conservation Commission Page 2 A copy of the taking and plan are recorded in the Hampshire Registry of Deeds, Book 596, Page 170 and 171. Thereafter, the stream was diverted to run in back of what is now Mr. Graves' land, under Barrett Street, under King Street and out to the Connecticut River, and this stream is therefor owned and controlled by the City of Northampton. I believe Mr. Huntley explained to you how this stream now drains some 425 acres or-more of the Prospect Street, Elm Street, Childs Park, Jackson Street area and how the bed of this stream has risen in height and overflowed onto the Graves' property, flooding it. This has occurred because of the failure to dredge and maintain the stream and to clear it of obstructions as a trip to the Barrett Street culvert will readily show. Mass.General Laws,Ch.83,§l relative to the con- struction and maintenance of sewers and drains provides in part: "Drains and sewers so laid out shall be built, repaired, maintained and owned by the town." This requirement that a city or town maintain its sewers and drains is not merely a idle requirement that can be ignored. As I understand, the City Engineers Office has, on occasion, requested money to dredge and clean this brook so as to fulfill the city's responsibility as set forth in Ch.83,§l but the money has not been provided. As far back as 1890 in the case of Bates v. The Inhabitants of Westborough, a town was held liable in tort for flooding the plaintiff's land with backwater from a drain. This drain had become choked up and obstructed. The jury awarded damages to the landowner on the basis of a complaint which said in part: "that it was the duty of the defendant (Town) to keep said drain clear and unobstructed but the defendants carelessly and negligently allowed the drain to become obstructed." as a result of which Plaintiff's land was flooded. T0: Northampton Conservation Commission Page 3 The Supreme Court, back in 1890, said in part: "The town has no prerogative to flood the lands or to stop the drains of'other land- owners without paying for it and if it does so without authority of law, is liable to an action of tort." At Page 82 "Thus, in the instance of sewers, it is settled that if the plaintiff can prove that the injury was caused by the negli- gence of the City, either in the original con- struction of the sewer or in not keeping it free from obstructions, he may maintain an action against the city * * * * so if by a system of drains, a City artificially diverts surface water from its natural course and accumulates it on the plaintiff's land in such quantities as to create a private nuisance, it may be liable to an action. * * * * So, if it negligently fails to keep a culvert under a highway in such condition as not to obstruct a natural stream." This case has been cited on numerous occasions and, in fact, the law is now even more stringent as far as the duty of landowners to abutters not to overflow or divert water onto their neighbors' land. In the case of Lobster Pot of Lowell v. Lowell, 333 Mass. 31, the Supreme Court held: "A municipality is not responsible for damages which accrue to individuals through any defect or inadequacy in the plan of its system of sewers but is responsible for damages which accrue to individuals in the contruction, maintenance or operation of its system of sewers. This principle also applies equally to drains or sewers. In the case of the plaintiff was entitled Brockton for damage to his the city to keep a highway to interrupt the flow of a Belkus v. Brockton, 282 Mass. 285,~ to recover damages from the city of property from negligent failure of culvert in such condition so as not natural water course which as a TO: Northampton Conservation Commission Page 4 flooded result,/his premises. The Court, in effect held that: "Where, however., damage is not a necessary result, but occurs because of conduct.of the municipality in performing or maintaining the authorized under- taking, there is no legitimate taking of property by legislative mandate; there is tortious action which entitles the injured person to redress from the wrongdoer. * * * * If the injury is permanent and unchanged by a cessation of the injurious action, the damage is the difference in the fair market value of the injured premises before and after the injury." It used to be that a landowner could with impunity grade and improve his land even though he thereby diverted surface water onto his neighbor's land and he was not liable. However, this principal of law called the "Common Enemy" approach to surface water problems has now been changed in Massachusetts by the decision of.Tucker v. Badoian, 376 Mass. 907 and the rule now is that one has an obligation to use reasonable care in the use of his property called the "Reasonable Use Standard". This standard was applied in a recent case where the Department of Public Works tried to claim they had the right to empty water through their drainage system onto the land of the plaintiff, Triangle Center. In the case of Triangle Center v. Dept. of Public Works, 386 Mass. 858, decided in 1982, the Massachusetts Supreme Court indicated towns and cities have no greater common law rights than the Gommonweaith and that the old rule which permitted land owners to divert surface water onto neighboring property was rigid and anarchic. They said: "The Government's right, expressed in Holleran, supra, and Turner, supra, to divert surface water from public ways onto neighboring property, is also rigid and anarchic." The court went on to say that the Department of Public Works had no right to discharge water onto the plaintiff's TO: Northampton Conservation Commission Page 5 land, that it created a private nuisance and at Page 865 said: "Other courts applying reasonable use analysis have held landowners suffering substantial damage from increased drainage to be entitled to relief against the public body without considering the cost of altering the drainage". Therefore, it is my opinion, clearly, that Mr. Graves has a substantial action of tort against the City of Northampton and that the damage to his property is far in excess of $125,000.00 at this point. It would, therefore, seem extremely prudent to me to permit Stop & Shop to rectify the harm which the City has done over the years by failing to maintain a stream and to open up the brook so the property can be drained and used. This would not only save the City very substan- tial costs of dredging the brook and repairing and replacing the culverts and also, hopefully, eliminate a very substantial tort claim which the City will have if the Conservation Commission does not look in a reasonable and fair manner at'the request of Stop & Shop. It seems to me not only is there a legal require- ment that the City fulfill its obligations but there certainly should be a moral obligation. If the City expects its citizens to obey laws and keep their property in good condition, the least that the City can do is set an example by doing likewise. The only reason why this property has become wet, based on Mr. Huntley's surveying and engineering logic, is the fact that the brook which is over 100 feet from the Graves property was allowed to backup, flood and saturate the Graves property thus threatening to make it nonusable if the Conservation Commission refuses to permit the City's errors to be remedied.

Introduction This report analyzes storm water runoff for the King Street Brook watershed (see figure 1), with the point of termination being the end of the Barrett Street-culvert. F` The purpose of this analysis is to determine the 10 and 100 year flood elevations of the King Street Brook between the railroad crossing and the Barrett Street culvert, for existing conditions and conditions after the proposed King Street fire station has been constructed. II. Calculations The attached calculations were performed on Hydrocad version 3.20 using SCS TR-20 methodology. The watershed area was broken into individual projects (as required by the computer program), containing subcatchment areas, reaches and ponds, which were then linked together. The project flow diagrams for each individual project, as well as a master flow diagram are attached. Watershed subcatchment areas, their runoff coefficients, pipe slopes and pipe diameters were provided by the City of Northampton Department of Public Works on a typewritten document titled "King Street Brook". The subcatchment area runoff coefficients were translated into SCS Curve Numbers. This was accomplished by correlating SCS Runoff Curve Numbers for ~r- soil type B with runoff coefficients for areas with similar types of coverage. This created a conversion chart to estimate the curve number (see figure 2). Subcatchment area time of concentrations were determined as follows: areas between 0 and 5 acres and between 5 and 10 acres were given time of concentrations equal to 5 and 10 minutes respectively. These values are based on an average calculated time of concentration for typical subcatchment areas in each size group. Areas greater than 10 acres in size have calculated time of concentrations, based on the SCS Curve Number Lag method. This was done due to the fact that small areas were not major contributors to runoff volume in comparison to large areas located directly adjacent to the King Street Brook. For calculated time of concentrations, the subcatchment area slopes were taken from the City of Northampton Topographic. Maps dated April of 1965, sheet numbers 23, 24 and 31. Reaches that subcatchment areas flow through were either underground drainage lines or open channels. Information for the drainage lines was obtained from the typewritten document provided by the City of Northampton Department of Public Works. Information for open channels and culverts was obtained from the City of Northampton Topographic Maps, site inspection and Northampton Bikeway Storm System plans dated 1987. The more conservative pipe diameters and pipe 1 King Street Broo._ Jrainage Analysis May 9,1997 slopes were taken from the King Street Brook document provide by the City of Northampton for any values in question. Manning's coefficients for the drain lines were assumed to be 0.013 and values for the open channels were based on site inspection and the attached table of Manning Roughness Coefficient taken from the Massachusetts Highway Manual. The King Street Brook from the railroad crossing to the Barrett Street culvert was modeled as a pond to determine the flood storage elevation. The pond size is based on site inspection and on the City of Northampton Topographic Maps. The outlet structure, the Barrett Street weir and culvert, was modeled using the as-built information provided by the City of Northampton Department of Public Works. The calculations assume that the King Street Brook, downstream of the Barrett Street Culvert, has been dredged. Calculations for the watershed area, for the 10 and 100 year storm frequencies, are attached for existing conditions as well as the proposed conditions after the proposed King Street fire station has been built. Information for the proposed King Street fire station, including hydrograph information and areas, were provided by Almer Huntley Jr. & Associates of Northampton, Massachusetts on May 9, 1997. 1 N. Summary The results of the calculations are shown in the following table: King Street Brook (Railroad to Barrett Street) 11 10 Year Storm Existing Proposed 100 Year Storm Existing Proposed Peak Elevation (ft) 144.0 144.0 144.7 144.8 Peak Flow Rate In (cfs) 184.3 179.3 328.0 317.9 Peak Flow Rate Out (cfs) . 53.3 53.4 80.3 81.4 Volume In (acre-ft) 37.9 38.2 64.2 64.6 Volume Out (acre-ft) 35.4 35.5 49.2 49.5 The values listed above are for the King Street Brook from the railroad through the Barrett Street culverts. The storm water runoff which enters into the center of the Barrett Street culvert is not reflected in these values. It is assumed that the peak runoff will enter and exit the Barrett Street culvert prior to the peak time for the watershed area. 2 i K r 3 Street Broo". Drainage Analysis May 9,1997 II As shown in the above chart, the peak flood elevation for the area between the railroad and Barrett Street did not change for the 10 year storm and increased for the 100 year storm by one tenth of a foot. The peak flow rates into the pond decreased due to the proposed detention basin for the fire station which attenuated the peak flow rate. The volume of runoff in and out of the brook have increased slightly, due to the proposed fire station.
