LECRENSKI, ) MEMORANDUM OF LAW IN SUPPORT OF Petitioner ) APPLICA nON FOR SITE PLAN APPROVAL ) ___________ -J) 384 Shoemaker Lane, Agawam, Mass. I. FACTS 1. The Petitioner, Theresa Lecrenski (the "Petitioner") is the owner of property known as 384 Shoemaker Lane and Lot 3 Moylan Avenue, Agawam, Massachusetts (the "Property"). The Property, which consists of two lots, was originally purchased by Frank Lecrenski, the Petitioner's late husband. The first lot was purchased on August 18, 1992, and the second lot was purchased on October 9, 1996. Subsequent to the purchase of the first lot, Frank Lecrenski submitted to, and received approval from, the Town of Agawam ("Agawam") of a site plan (the "1992 Site Plan") setting forth the intended use of the Property as a school bus parking lot and the existence of a parking area covered with compacted gravel. Since that time, the use of compacted gravel at the Property for parking areas has remained consistent with the terms of the 1992 Site Plan. 2. The Petitioner has contracted to sell the Property to the Lower Pioneer Valley Educational Corporation (the "LPVEC") for the continued use as a school bus parking lot. As part of this use, the LPVEC intends to maintain the current use of the Property with currently existing levels of service. This level of service has increased since 1992 and, as such, the Petitioner has submitted a new site plan (the ''2012 Site Plan") which describes the details of the modified use in compliance with Section 180-13 of the Agawam Zoning Ordinance (the "Ordinance"). 3. Consistent with the current conditions at the Property, the 2012 Site Plan details the continued use of compacted gravel for the parking area. The Agawam Planning Board bas requested that the Petitioner consider revising the 2012 Site Plan to ensure that the parking area be paved with asphalt. II. THE APPLICA nON AND USE OF SITE PLAN REVIEW A. THE USE OF SITE PLAN REVlEW IS GENERAlLY ALLoWED The Massachusetts Zoning act (G.L. c. 4OA) is silent as to the requirement and use of site plans by local zoning authorities. Nevertheless, Massachusetts courts have explicitly recognized and approved the use of the site plan review mechanism since the 1970 decision of the Supreme Iudicial Court in Y.D. Dugout, Inc. v. Bd. of Appeals of Canton, 357 Mass. 25. {24843.5.00175051.1XlC;2 } I • • B. WHERE USE Is As OF RIGHT. ONLY REASONABLE CONDmONS CAN BE IMPoSED If a use (or proposed use) of a property is allowed as a matter of right under the local zoning ordinance, the site plan review process cannot be used to result in the outright prohibition of such use but, instead, can only impose "reasonable terms and conditions" on the use. Dufault v. Millennium Power Partners, LP., 49 Mass.App.Ct. 137, 139 (2000); Prudential Insurance Company of America v. Board of Appeals of Westwood, 23 Mass.App.Ct. 278 (1986). C. JUSTIFICATION FOR SITE PLAN CONDmONS SHOULD BE SUFPORTED By PuRPOSES OF ZoNING ORDINANCE AND SITE PLAN REvmw A recent Appellate Court case shows that conditions imposed as part of the site plan review mechanism should be supported by the express purposes of the local zoning ordinance or of the site plan review process. In Castle Hill Apartments Ltd. Partnership v. Planning Bel. of Holyoke, 65 Mass.App.Ct. 840 (2006), the plaintiff was subject to a requirement, imposed by the planning board as part of the site plan review, for additional entrances into a development of multi-family dwellings. This requirement would result in a configuration of buildings with significantly less density than allowed under the applicable zoning ordinance. The Court detennined the planning board's justification (that "visual and environmental qualities of the site" required the condition) was too vague, and that the requirement was not otherwise allowed because reducing the density of a project was not part of the criteria for site plan review under the Holyoke zoning ordinance. ill. THE REOUIREMENT THAT THE PARKING AREA BE PA YED WITH ASPHALT IS NOT REASONABLE. IS NOT SUPPORTED BY THE ZONING ORDINANCE. AND IS CONTRARY TO THE GOALS OF THE AGAWAM ZONING ORDINANCE A. REQUIRING THE PARKING AREA To BE PAVED WITH ASPHALT WILL IMPoSE AN UNREASONABLE EXPENSE ON THE PETITIONER Pursuant to discussions with Mark Darnold of Berkshire Design Group, Inc. (the site engineer), the proposed condition that the parking area at the Property be paved with asphalt will require the Petitioner to expend between an additional $120,000 and $150,000, including additional grading, drainage, and materials. Further, the use of asphalt for the parking area will require significantly higher maintenance expenses in upcoming years, as the asphalt paving will be more likely to buckle, crumble, and disintegrate over time. In contrast, the use of compacted gravel for parking areas is generally accepted within the design, construction and building fields as an effective and efficient method of maintaining a clearly delineated parking area and preventing undue dust from accumulating. The use of the Property as a parking area for school buses exemplifies the unreasonableness of this condition. Typically, a bus will be driven out of the Property early in the morning, complete a route, be returned to the Property later in the morning, be driven out of the Property early in the afternoon, complete a route, and be returned to the Property later in the {24843.S.0017SOS1.DOC;2 ) 2 • • afternoon. In total, a bus will come in and out of its parking space twice per school day; in other words, each parking space will be used approximately only three-hundred and sixty times per year. This minimal use (and the corresponding mjnjmal wear and tear expected in the parking area) clearly shows that the significant expense being requested in unreasonable. B. THE ZONlNG ORDINANCE DOES NOT PROVIDE SUPPORT FOR THE REOUlREMENT THAT THE PARKING AREA BE PAVED Wrrn ASPHALT The purposes of the Ordinance include "promoting the health, safety, convenience, morals, and welfare of [Agawam's] inhabitants" and "to lessen congestion in the streets, to secure safety from fire, panic and other danger, to provide adequate light and air, to prevent the overcrowding of land, to avoid undue concentration of population, to facilitate the adequate provision of transportation, water, sewerage, schools, parks and other public requirements, and to increase the amenities of [Agawam]." Ordinance, § 180-1. While the site plan review process makes clear that a site plan is required to reflect changes in parking areas, and that such site plans should detail those changes, it does not set forth any criteria for approving site plans which relate directly to the use of any specific material for parking areas. Ordinance, § 180-13. Likewise, the section of the Ordinance addressing uses within an Industrial-B zone does not speak to this issue. Ordinance, § 180-61 -§ 180-66. Here, no portion of the Ordinance expresses justification for requiring the parking area at the Property be paved with asphalt instead of utilizing compacted gravel. In light of the unreasonable expense, the imposition of such a condition is unwarranted. C. THE REOUIREMENT THAT THE PARKING AREA BE PAVED Wrrn ASPHALT Is CON'IRARY To THE GoALS OF THE AGAWAM ZONlNG ORDINANCE Ironically, the condition being requested is actually contrary to the purposes described above. The use of asphalt, as compared to compacted gravel, will result in significant environmental impacts. Beyond the amount of crude oil and energy required to make the asphalt itself, using it to pave the parking area will sharply reduce the amount of rain water which can frod its way back into the underlying soil. In contrast, the use of compacted gravel would allow this water to drip through and be absorbed. Further, excessive use of asphalt pavement sharply increases the amount of Total Suspended Solids ("TSS") which can be found in such runoff, and, as a result of the heat which can be held by asphalt pavement, also often has the unintended effect of raising the temperature of such runoff. Both increased TSS and increased water temperature can have substantial negative impacts on local ground and sub-surface water supplies. (For further reference, see "Stormwater Management Policy," Mass. Dept. of Environmental Protection; "Changes to the Massachusetts Stormwater Management Standards," Mass. Dept. of Environmental Protection; and, ''For Municipal Boards: Halting Stormwater Runoff's Harmful Effects on Community Waters," Massachusetts Watershed Coalition.) {24843..'i.OO17~OSI.DOC;2 ) 3 • • Finally, it should be noted that school buses are inspected three times per year by state officials, and that the inspection includes ensuring that no oils or fluids are leaking from the vehicle. This regular (and strictly enforced) inspection will help address any concerns that such fluids may reach the soil. Ill. CONCLUSION Only reasonable conditions may be imposed as part of the site plan review process, and these conditions must be supported by the local zoning ordinance. Here, the requested condition is unreasonable considering both its cost and the lack of any pressing need. Further, not only is the condition not supported by the Ordinance, it would actually act contrary to the purposes set forth in the Ordinance by decreasing the amount of rain water that can be absorbed by the sub- surface soil, and increasing the amount of pollutants to be found in the resulting runoff. For these reasons, the Petitioner respectfully requests that the Planning Board accept and approve the site plan as submitted. Peter Dated: January 19,2012 (248435.0017SOS1.DOC;2 ) 4 WILLIAM F.

STRUHS Col'lllDiaioner Stormwater MlIII8geIIIent Policy The goal of the Stormwater Management Policy is to improve water quality and address water quantity problems by the implementation of performance standards for stormwater management. Urban runoff and discharges from stormwater outfalls are the single largest source responsible for water quality problems in the Commonwealth's rivers, lakes, ponds, and marine waters_ The Stormwater Management Standards establish clear and consistent guidelines for stormwater management in Massachusetts_ The Standards are designed for use under multiple statutory and regulatory authorities of the Department of Environmental Protection, including the Wetlands Protection Act, as amended by the Rivers Protection Act, and the Clean Water Act_ Stormwater discharges occur as rainfall and snow melt carries pollutants to surface and groundwater: New and existing development increases imperVious surfaces, which alters natural drainage features, increases peak discharge rates and volumes, andreduces recharge to mainiain wetlands and basefldws in streams. Development also results in corresponding increases in the concentration and types of pollutant loadings, including nutrients, solids, metals, salt, pathogens, pesticides, and hydrocarbons. Best Management Practices (BMPs) reduce or prevent pollutants from reaching water bodies and control the quantity of runoff from a site. The Stormwater Management Standards address both water quality (pollutants) and water quantity (flood control) problems by establishing the level of required controls through the use of BMPs. The Stormwater Management Standards are intended to be applied during routine project review by issuing authorities under the Wetlands Protection Act. Use of the standards should prevent or minimize adverse environmental impacts due to unmanaged stormwater while limiting undue costs and recognizing site constraints. Applicants should submit the stormwater form developed by DEP which presents in a simple and concise format how the Stormwater Management Standards have been met. The form will allow Commissions and the Department easy access to the stormwater management components of the project, and should simplify the review process for the applicant.

Staunch it at its source With cinder loads dumped down? The brook was thrown Deep in a sewer dungeon under stone In fetid darkness still to live and run - And all for nothing it had ever done" From "A Brook in the City" By Robert Frost Stormwater runoff results from rainfall and snow melt It represents the single largest source responsible for water quality impairments in the Commonwealth's rivers, lakes, ponds, and marine waters. New projects and redeveloped areas typically add impervious surfaces that, when not properly managed, alter natural drainage features, increase peak discharge rates and volumes, reduce recharge to wetlands and streams, and increase the discharge of pollutants to wetlands and water bodies. In 1996 the Massachusetts Department of Environmental Protection (MassDEP) issued a Stormwater Policy that established Stormwater Management Standards (Standards) aimed at encouraging recharge and preventing stormwater discharges from causing or contributing to the pollution of the surface waters and ground waters of the Commonwealth. By state action, these Standards are applied in areas subject to the jurisdiction under the Massachusetts Wetlands Protection Act. In addition, through local bylaws, some municipalities arc applying these Standards to upland areas. Applied to areas under the jurisdiction of local Conservation Commissions, the Stormwater Policy and the Stormwater Handbook, which was first published in 1997, provided guidance for how to address potential water quality (e.g., pollutants) and water quantity (e.g., flooding, low base flow, and recharge) problems by establishing standards that require the implementation of a wide variety of stormwater IIl8Iillgement strategies. What is MassDEP Trying To Accomplish? Since the mid-1990s, we have learned much more about stormwater in Massachusetts. The Massachusetts Water Resources Commission identified many Massachusetts water basins as "stressed" due to increased withdrawals of water. MassDEP publishes lists of "impaired waters" identifying those surface waters that are failing to meet minimum state standards for water quality. Nationally, the movement towards stormwater Best Management Practices (BMPs) that mimic natural hydrology (e.g., Low Impact Design) have successfully increased local recharge and significantly reduced pollutants flowing into nearby waters and streams. As published in the January 15,2008 AMWS Newsletter , • • BGY For Municipal Boards: Halting Stonnwater Runoffs Harmful Effects On Communit... Page 1 of 2 BGY For Municipal Boards: Halting Stormwater Runoff's Harmful Effects On Community Waters " ... virtually nothing has been written about the trout-fishing opportunities in eastem Massachusetts -not @ because there are well-kept secrets, but because there are no such opportunities worth mentioning. Some of the scummy streams that flow behind strip malls and through culverts support populations of stocked trout for a month or two in the spring, until the heat and drought and toxic runoff get them." William G. Tapply, Everv Day Was Special. 2010, p.S6 Cold water streams are badly impacted by runoff and native trout have vanished from many brooks in densely developed places. Recreational lakes are another problem, as pollutants carried by streams feed the growth of invasive weeds and raise bacteria levels. State assessments find that two-thirds of local lakes and ponds are impaired, largely due to stormwater. But healthy waters can be restored through the cleansing of storm runoff by community actions, Many low-cost and no-cost measures can reduce municipal expenses for water treatment and maintenance of storm sewers. These solutions also help communities to comply with state and federal mandates for eliminating stormwater discharges into streams. Municipal Boards Municipal boards work hard to protect community health, safety and welfare. Public opinion surveys find water pollution is a top environmental concem. Yet few people know that stormwater is the main source of pollution, and how inexpensive practices can halt its harmful impacts on community waters. Many municipal officials need information about stormwater for routine decisions on land development and redevelopment projects. Stormwater workshops sponsored by project partners during the past three years continue to be well-attended by municipal boards (see www.commonwaters.Orglevents). We have also prepared guidance that can assist towns to apply state and federal stormwater policies. Municipal boards are on front line for implementing these evolving stormwater policies and regulations. Communities with storm sewer systems are regulated by EPA permits for stormwater discharges to local waters, which require cities and towns to: Inform and involve community residents in preventing runoff problems Eliminate illegal discharges into storm drainage systems Contra! construction site runoff Examine local street and parking lot regulations to reduce runoff to streams Manage stormwater from new development and redevelopment Maintain good housekeeping and pollution prevention for municipal operations Municipal planning boards, conservation commissions and public works! highway departments are key officials because their activities can deter stormwater impacts. Conservation Commissions are the primary boards responsible for the MassDEP stormwater regulations under the state Wetlands Protection Act. The DEP Stonnwater Handbook includes detailed guidance for stormwater management standards (Vol. 1, Ch. 1) and technical specifications for best management practices (Val. 2, Ch. 2). This Stormwater Handbook is available for download from the DEP website and supplies a wealth of useful information. Additional guidance for Ten Ways Conservation Commissions Can Protect Cold Water Streams and The;r Inhabitants is available for download on this website [provide link & post guidance document]. Planning Boards are the primary boards for encoureging Low Impact Development (LID) practices that will protect and improve the health of local streams, lakes and water supplies.

MEMORANDUM JAN 0 4 2012 , P if~ M~'~ '. \ ,1 (3 BOAHU Michelle Chase, Rick Seidnitzer, Planning Board Members Eric Melle December 30, 20 II Project: Five Star -Bus Parking ShoemakerlMoylan Lane Please review the responses to comments raised during the Engineering review and subsequert Planning Board Meeting on December I SIb, 2011. Town of Agawam -Engineering 1. As per AASHTO design parameters regarding buses, driveway aisle widths should be at least 45,5 Ft. for bus turning movements. These movements are somewhat restricted on the proposed plan (see attached). Aisle widths have been increased to 45.5-ft. 2. The proposed site development is fairly flat. The plan should include spot elevations along the perimeter to indicate that the post development stormwater flows are being directed to the proposed infiltration basin. The pre-developed area (lot with existing building) is not to be part of the new stormwater design. Add grading information on this pre-developed area to indicate this. Existing contours and proposed spot grades have been added to the plan. 3. The existing flared end located to the south of Moylan Lane should be added to the plan, this will show where the proposed stormwaler runoff ties into the Town's existing drainage system. The existing flared end section has been added to the plan by the surveyor 4. Please clarify how the 50% impervious area credit for the Moylan Lane lot was applied to the stormwater calculations (if at all) The Moylan Lane lot did not consider the 25% impervious credit, because except for the driveway apron, there are no new impervious surfaces proposed. In addition, as shown on the pre and post drainage figures, the existing lot (Shoemaker Lane) was receiving a large portion of runoff from the undeveloped northerly lot (Moylan Lane). The proposed project includes 4 Allen Place' Northampton, Massachusetts 01060 • t 413.582.7000 • f 413.582.7005 • bdg@berkshiredesign.com • • redirecting the majority of runoff generated on the Moylan Lane lot, as well as a portion of runoff from the northern side of the existing building to the proposed infiltration basin. Once proposed construction activities have been completed, 4,035 square feet of asphalt from the northern side of the existing building will be directed to the proposed infiltration basin. This area of asphalt was originally a contributing area to the existing Shoemaker Lane lot drainage system. As a result of this reduction in impervious area contributing to the existing drainage system, the proposed project does not include the removal of 2,250 square feet of asphalt from the southern edge of the existing parking lot. This 2,250 square foot area of pavement was installed during the construction of the existing Shoemaker lot in excess of the approved site plan dated September 17, 1992. 5. Add sun>ey data (metes & bounds) to all lot lines on at least one sheet. Metes and bounds have been added to all lot lines by the surveyor. 6. It is recommended that the flat concrete weir in the infiltration basin be replaced with a geotextile anti-erosion grid. Please contact us if a detail is needed. The concrete weir has been replaced with a geotextitle anti-erosion grid and the detail has been revised. 7. All existing catch basins should have a silt sac installed during construction. Add a silt sac detail to the plan. Silt sacs are now proposed for every catch basin and the detail has been added to the detail sheet. 8. SpecifY what type of gravel is proposed. The gravel type is trap rock gravel gradation and has been added to the detail 9. At the new asphalt apron on Moylan Lane change the HMA radii to 25-ft. All areas of this apron located within the ROW should be at least 2% cross slope toward the roadfor drainage purposes. The asphalt apron should be extended to 50-ft instead of 20-ft as shown on the plan to reduce the amount of gravel that is tracked into Moylan Lane. Please also revise detail 4 on SP. 4 The radii of the asphalt apron on Moylan Lane have been changed to 2S-ft, specified to have a 2% cross slope and the detail has been revised 10. Add radii information for all grass locations in parking areas. All radii information has been added to the plans 11. Areas of available snow storage should be indicated on the plan. Snow storage information has been added to the plans 4 Allen Place' Northampton, Massachusetts OJ 060 • t 413.582.7000 • f 413.582.7005 • bdg@berkshiredesign.com • • • 12. The plans indicate that the existing catch basins are full of mud and the inverts were not located. These CBs and pipes should be cleaned out. Hoods should be installed in each in each CB. Also, a Construction and Post-Construction Operations and Maintenance plan for these CBs should be proposed to ensure that the drainage system operates as intended All applicable details and notes should be added to the plans. The Operations and Maintenance plan has been updated to include Catch Basin cleaning, restoration and hood installation. The post-construction Operations and Maintenance plan has been updated to include inspection and maintenance instructions. A hood installation detail and applicable notes have been added to Site plan package. 13. The proposed parking stalls on the compacted trap rock gravel will require repainting more often than if painted on HMA. This will be necessary to prevent encroachment of adjoining stalls because of loss of striping through wear and tear on the gravel surface. Repainting will also maintain the proposed number of stalls. A Maintenance Schedule should be proposedfor the gravel area and should include painting parking spaces and re-establishing the grassy areas as delineated on the plans. Winter snow removal operations will also add to this wear and tear condition. Although the interface between grassed and gravel surfaces will be delineated, the proponent is not anticipating painting the parking stalls on the trap rock gravel parking area surface. A maintenance schedule for the gravel parking lot and associated landscaped islands has been included in the Operations and Maintenance Plan within the stormwater management report. 14. Sheet SP.2 has comments regarding multiple vehicle use of the proposed parking stalls: "mini-bus spaces can be used as passenger spaces ", & "bus parking spaces can be usedfor passenger cars while drivers are working". Coordinating this will be extremely difficult; likely resulting in vehicles being parked in areas, which may impede the intended overall use of the site. The overall number of passenger car sized spaces has been increased significantly to alleviate the majority of this coordination 15. On Sheet AT. J the auto-turn movements show the busses going into adjacent parking spaces. These movements would not be possible if another bus is in one of those spaces. Lanes have been widened to 45 .5-ft where buses will make 180 degree turning movements 4 Alien Place' Northampton.

Include the attached accessible sign detail. Accessible spaces have been widened to 9-ft. However, the sidewalk in front of the existing building is flush with the parking lot and the sidewalk is flush with the front door. Planning Board Comments: 1. Demarcate edge of islands and edge of gravel The edge of grassed islands have been demarcated with 2"X6" recycled plastic edging. 2. Demarcate edge of infiltration basin The edge of the infiltration basin shall be delineated with 6"X6" pressure treated posts and PVC chains place \5.5-ft on center 3. 20' spaces in center row of parking to be reduced to 18' in order to widen the bus travel lanes Bus lanes have been increased to 45 .5' and the parking configuration has been modified. 4. Add lighting to satisfY zoning requirements There are no zoning requirements that address lighting in the Industrial B zone, however the project proponent is proposing wall pack lighting to be installed on the existing building 5.

The Petitioner, Theresa Lecrenski (the "Petitioner',) is the owner of property known as 384 Shoemaker Lane and Lot 3 Moylan A venue, Agawam, Massachusetts (the "Property"). The Property, which consists of two lots, was originally purchased by Frank Lecrenski, the Petitioner's late husband. The flrst lot was purchased on August 18, 1992, and the second lot was purchased on October 9, 1996. Subsequent to the purchase of the flrst lot, Frank Lecrenski submitted to, and received approval from, the Town of Agawam ("Agawam") of a site plan (the "1992 Site Plan") setting forth the intended use of the Property as a school bus parking lot and the existence of a parking area covered with compacted gravel. Since that time, the use of compacted gravel at the Property for parking areas has remained consistent with the terms of the 1992 Site Plan. 2. The Petitioner has contracted to sell the Property to the Lower Pioneer Valley Educational Corporation (the "LPVEC") for the continued use as a school bus parking lot. As part of this use, the LPVEC intends to maintain the current use of the Property with currently existing levels of service. This level of service has increased since 1992 and, as such, the Petitioner has submitted a new site plan (the "2012 Site Plan") which describes the details of the modifled use in compliance with Section 180-13 of the Agawam Zoning Ordinance (the "Ordinance") . 3. Consistent with the current conditions at the Property, the 2012 Site Plan details the continued use of compacted gravel for the parking area. The Agawam Planning Board has requested that the Petitioner consider revising the 2012 Site Plan to ensure that the parking area be paved with asphalt. IT. THE APPUCA TION AND USE OF SITE PLAN REVIEW A. THE USE OF SITE PLAN REVlEW IS GENERALLY ALLoWED The Massachusetts Zoning act (G.L. c. 4OA) is silent as to the requirement and use of site plans by local zoning authorities. Nevertheless, Massachusetts courts have explicitly recognized and approved the use of the site plan review mechanism since the 1970 decision of the Supreme Judicial Court in Y.D. Dugout, Inc. v. Bd. of Appeals of Canton, 357 Mass. 25. {24843.S.0017S051.DOC;2 I 1 B. WHERE USE Is As OF RIGHT. ONLY REASONABLE CONDmONS CAN BE IMPOSED If a use (or proposed use) of a property is allowed as a matter of right under the local zoning ordinance, the site plan review process cannot be used to result in the outright probibition of such use but, instead, can only impose "reasonable terms and conditions" on the use. Dufault v. Millennium Power Partners, LP., 49 Mass.App.Cl 137, 139 (2000); Prudential Insurance Company of America v. Board of Appeals of Westwood, 23 Mass.App.Ct. 278 (1986). C. JUSTIFICATION FOR SITE PLAN CONDmONS SHOUlD BE SUPPORTED By PuRPoSES OF ZoNING ORDINANCE AND SITE PLAN REVIEW A recent Appellate Court case shows that conditions imposed as part of the site plan review mechanism should be supported by the express purposes of the local zoning ordinance or of the site plan review process. In Castle Hill Apartments Ltd. Partnership v. Planning Bd. of Holyoke, 65 MassApp.Ct. 840 (2006), the plaintiff was subject to a requirement, imposed by the planning board as part of the site plan review, for additional entrances into a development of multi-family dwellings. This requirement would result in a configuration of buildings with significantly less density than allowed under the applicable zoning ordinance. The Court determined the planning board's justification (that "visual and environmental qualities of the site" required the condition) was too vague, and that the requirement was not otherwise allowed because reducing the density of a project was not part of the criteria for site plan review under the Holyoke zoning ordinance. m. THE REOUIREMENT THAT THE PARKING AREA BE PAVED WITH ASPHALT IS NOT REASONABLE. IS NOT SUPPORTED BY THE ZONING ORDINANCE. AND IS CONTRARY TO THE GOALS OF THE AGAWAM ZONING ORDINANCE A. REoUlRlNG THE PARKING AREA To BE PAVED Wrm AsPHALT WIlL IMPoSE AN UNREASONABLE EXPENSE ON THE PETITIONER Pursuant to discussions with Mark Darnold of Berkshire Design Group, Inc. (the site engineer), the proposed condition that the parking area at the Property be paved with asphalt will require the Petitioner to expend between an additional $120,000 and $150,000, including additional grading, drainage, and materials. Further, the use of asphalt for the parking area will require significant! y bigher maintenance expenses in upcoming years, as the asphalt paving will be more likely to buckle, crumble, and disintegrate over time. In contrast, the use of compacted gravel for parking areas is generally accepted within the design, construction and building fields as an effective and efficient method of maintaining a clearly delineated parking area and preventing undue dust from accumulating. The use of the Property as a parking area for school buses exemplifies the unreasonableness of this condition. Typically, a bus will be driven out of the Property early in the morning, complete a route, be returned to the Property later in the morning, be driven out of the Property early in the afternoon, complete a route, and be returned to the Property later in the (24843.S.0017SOS1.DOC;2 ) 2 afternoon. In total, a bus will come in and out of its parking space twice per school day; in other words, each parking space will be used approximately only three-hundred and sixty times per year. This minimal use (and the corresponding minima1 wear and tear expected in the parking area) clearly shows that the significant expense being requested in unreasonable. B. THE ZONlNG ORDlNANCE DOES NOT PROVIDE SUPPORT FOR mE REOUlREMENT THAT THE PARKING AREA BE PAVED WITH ASPHALT The purposes of the Ordinance include ''promoting the health, safety, convenience, morals, and welfare of [Agawam's] inhabitants" and "to lessen congestion in the streets, to secure safety from fire, panic and other danger, to provide adequate light and air, to prevent the overcrowding of land, to avoid undue concentration of population, to facilitate the adequate provision of transportation, water, sewerage, schools, parks and other public requirements, and to increase the amenities of [Agawam]." Ordinance, § 180-1. While the site plan review process makes clear that a site plan is required to reflect changes in parking areas, and that such site plans should detail those changes, it does not set forth any criteria for approving site plans which relate directly to the use of any specific material for parking areas. Ordinance, § 180-13. Likewise, the section of the Ordinance addressing uses within an Industrial-B zone does not speak to this issue. Ordinance, § 180-61 -§ 180-66. Here, no portion of the Ordinance expresses justification for requiring the parking area at the Property be paved with asphalt instead of utilizing compacted gravel. In light of the unreasonable expense, the imposition of such a condition is unwarranted. C. THE REOUlREMENT THAT THE PARKING AREA BE PAVED WITH ASPHALT Is CONTRARY To niB GoALS OF THE AGAWAM ZONlNG ORDlNANCE Ironically, the condition being requested is actually contrary to the purposes described above. The use of asphalt, as compared to compacted gravel, will result in significant environmental impacts. Beyond the amount of crude oil and energy required to make the asphalt itself, using it to pave the parking area will sharply reduce the amount of rain water which can fmd its way back into the underlying soil. In contrast, the use of compacted gravel would allow this water to drip through and be absorbed. Further, excessive use of asphalt pavement sharply increases the amount of Total Suspended Solids ("TSS") which can be found in such runoff, and, as a result of the heat which can be held by asphalt pavement, also often has the unintended effect of raising the temperature of such runoff. Both increased TSS and increased water temperature can have substantial negative impacts on local ground and sub-surface water supplies. (For further reference, see "Stormwater Management Policy," Mass. Dept. of Environmental Protection; "Changes to the Massachusetts Storrnwater Management Standards," Mass. Dept. of Environmental Protection; and, "For Municipal Boards: Halting Storrnwater Runoff's Harmful Effects on Community Waters," Massachusetts Watershed Coalition.) {24843.5.00171051.DOC;2 } 3 Finally, it should be noted that school buses are inspected three times per year by state officials, and that the inspection includes ensuring that no oils or fluids are leaking from the vehicle. This regular (and strictly enforced) inspection will help address any concerns that such fluids may reach the soil. Ill. CONCLUSION Only reasonable conditions may be imposed as part of the site plan review process, and these conditions must be supported by the local zoning ordinance. Here, the requested condition is unreasonable considering both its cost and the lack of any pressing need. Further, not only is the condition not supported by the Ordinance, it would actually act contrary to the purposes set forth in the Ordinance by decreasing the amount of rain water that can be absorbed by the sub- surface soil, and increasing the amount of pollutants to be found in the resulting runoff. For these reasons, the Petitioner respectfully requests that the Planning Board accept and approve the site plan as submitted.

STRUHB CommiseioDer The goal of the Stormwater Management Policy is to improve water quality and address water quantity problems by the implementation of performance standards for stormwater management. Urban runoff and discharges from stormwater outfalls are the single largest source responsible for water quality problems in the Commonwealth's rivers, lakes, ponds, and marine waters. The Stormwater Management Standards establish clear and consistent guidelines for stormwater management in Massachusetts. The Standards are designed for use under multiple statutory and regulatory authorities of the Department of Environmental Protection, including the Wetlands Protection Act, as amended by the Rivers Protection Act, and the Clean Water Act. Stormwater discharges occur as rainfall and snow melt carries pollutants to surface and groundwater. New and existing development increases impervious surfaces, which alters natural drainage features, increases peak discharge rates and volumes, and reduces recharge to maintain wetlands and baseflows in streams. Development also results in corresponding increases in the concentration and types of pollutant loadings, including nutrients, solids, metals, salt, pathogens, pesticides, and hydrocarbons. Best Management Practices (BMPs) reduce or prevent pollutants from reaching water bodies and control the quantity of runoff from a site. The Stormwater Management Standards address both water quality (pollutants) and water quantity (flood control) problems by establishing the level of required controls through the use of BMPs. The Stormwater Management Standards are intended to be applied during routine project review by issuing authorities under the Wetlands Protection Act. Use of the standards should prevent or minimize adverse environmental impacts due to unmanaged stormwater while limiting undue costs and recognizing site constraints. Applicants should submit the stormwater form developed by DEP which presents in a simple and concise format how the Stormwater Management Standards have been met. The form will allow Commissions and the Department easy access to the stormwater management components of the project, and should simplify the review process for the applicant. 1'1* iufonBadoD" avaUabieiDatte.raate ronut. caU Aprel McCabe, ADA CoordiDator at 1""17-556-1171.

Staunch it at its source With cinder loads dumped down? The brook was thrown Deep in a sewer dungeon under stone In fetid darkness still to live and run - And all for nothing it had ever done .. From "A Brook in the City" By Robert Frost Stormwater runoff results from rainfall and snow melt. It represents the single largest source responsible for water quality impairments in the Commonwealth's rivers, lakes, ponds, and marine waters. New projects and redeveloped areas typically add impervious surfaces that, when not properly managed, alter natural drainage features, increase peak discharge rates and volumes, reduce recharge to wetlands and streams, and increase the discharge of pollutants to wetlands and water bodies. In 1996 the Massachusetts Department of Environmental Protection (MassDEP) issued a Stormwater Policy that established Stormwater Management Standards (Standards) aimed at encouraging recharge and preventing stormwater discharges from causing or contributing to the pollution of the surface waters and ground waters of the Commonwealth. By state action, these Standards are applied in areas subject to the jurisdiction under the Massachusetts Wet1ands Protection Act. In addition, through local bylaws, some municipalities are applying these Standards to upland areas. Applied to areas under the jurisdiction of local Conservation Commissions, the Stormwater Policy and the Stormwater Handbook, which was first published in 1997, provided guidance for how to address potential water quality (e.g., pollutants) and water quantity (e.g., flooding, low base flow, and recharge) problems by establishing standards that require the implementation of a wide variety of stormwater management strategies. What is MassDEP Trying To Accomplish? Since the mid-1990s, we have learned much more about stormwater in Massachusetts. The Massachusetts Water Resources Commission identified many Massachusetts water basins as "stressed" due to increased withdrawals of water. MassDEP publishes lists of "impaired waters" identifying those surface waters that are failing to meet minimum state standards for water quality. Nationally, the movement towards stormwater Best Management Practices (BMPs) that mimic natural hydrology (e.g., Low Impact Design) have successfully increased local recharge and significantly reduced pollutants flowing into nearby waters and streams.

William G. Tapply, Every Day Was Special, 2010, p.S6 Cold water streams are badly impacted by runoff and native trout have vanished from many brooks in densely developed places. Recreational lakes are another problem, as pollutants carried by streams feed the growth of invasive weeds and raise bacteria leve ls. State assessments find that two-thirds of local lakes and ponds are impaired, largely due to stormwater. But healthy waters can be restored through the cleansing of storm runoff by community actions. Many low-cost and no-cost measures can reduce municipal expenses for water treatment and maintenance of storm sewers. These solutions also help communities to comply wnh state and federal mandates for eliminating stormwater discharges into streams. Municipal Boards Municipal boards work hard to protect community health, safety and weijare. Public opinion surveys find water pollution Is a top environrnentaJ concem. Yet few people know that stormwater is the main source of pollution, and how inexpensive practices can halt ns harmful impacts on commun ~y waters. Many municipal officials need information about stormwater for routine decisions on land development and redevelopment projects. Stormwater workshops sponsored by project partners during the past three years continue to be well-attended by municipal boards (see www.commonwaters.orglevents). We have also prepared guidance that can assist towns to apply state and federal stormwater policies. MuniCipal boards are on front line for implementing thasa evolving stormwater policies and regulations. Commun~ies w~h storm sewer systems are regulated by EPA parm~s for stormwater discharges to local waters, which require crties and towns to: Inform and involve community residents in preventing runoff problems • Eliminate illegel discharges into storm drainage systems • Control construction s~e runoff Examine local street and parking lot regulations to reduce runoff to streams Manage stormwater from new development and redevelopment Maintain good housekeeping and pollution prevention for muniCipal oparations Municipal planning boards, conservation commissions and public works! highway departments are key officials because their activities can deter stormwater impacts.

Page I 2 2 2 3 3 4 Five Star Transportation December 30,2011 Agawam, Massachusetts Stormwater Drainage Report I. Introduction The following report presents an analysis of the storm water management system for the proposed gravel parking area at the Five Star Transportation Facility located at 384 Shoemaker Lane in Agawam, Massachusetts. The proposed project includes a new gravel parking lot and stormwater management system. The existing site contains 2 parcels which will be combined as a part of this project. The north parcel (where the new gravel lot will be constructed) currently contains grass/dirt areas in which overflow parking from the southern parcel uses. The southerly parcel contains a building and parking area, which has been expanded upon from what the previously approved site plans show. In order to ensure that no negative storm water impacts occur as a result of the proposed project, the existing site will be returned to the previously approved plan during construction in addition to the construction of the new stormwater management system for the new gravel parking area. II. Site Terrain and Soils The new parking area project site generally consists of grass & dirt and generally drains toward the west edge of the site, which contains a low spot that connects to a culvert draining under Moylan Lane. The USDA Soil Survey of Hampden County, Massachusetts, Central Part report classifies the site soils as (see Figure 3 for Soil Map): • (254A) Merrimac Sandy Loam Hydrologic Group: A • (255B) Windsor Loamy Sand Hydrologic Group: A • (32A) Wareham Loamy Sand Hydrologic Group: C Note: Test Pits hcrve been conducted on site and generally represent similar conditions to those classified by the USDA Soil Survey. See Appendix B for Test Pit Logs. III. Existing Conditions The existing site contains I drainage area (E-I see Figure I) and a control point (E-CP see Figure I) which is a low area located at the northwest portion of the parcel, in which all runoff within the area of work currently drains to. The The Berkshire Design Group, Inc. Page 2 Five Star Transportation December 30, 20 II Agawam, Massachusetts Stonnwater Drainage Report drainage area and control point are shown on the Pre-Development Drainage Area Plan (see Figure I). The foHowing is a description of the existing drainage area. E-I E-I is approximately 1.13 acres and contains grass/dirt areas. The area sheet flows toward the low spot at the northwest comer of the property which is used as the control point for determining peak flows and volumes for both existing and proposed conditions (shown as E-CP on Figure I). The low spot drains to a culvert that conveys the runoff under Moylan Lan:, to a large depressed area on the north side of Moylan Lane. IV. Proposed Conditions The existing site contains I drainage area (P-I see Figure 2) and a control point (P-CP see Figure 2) which is a low area located at the northwest portion of the parcel, in which all runoff within the area of work currently drains to. The drainage area and control point are shown on the Post-Development Drainage Area Plan (see Figure 2). The following is a description of the proposed drainage area P-l P-I is approximately 1.752 acres and contains gravel parking, an infiltration basin, and grass areas. This area is directed to the infiltration basin, whlch has been designed over the sandiest portion of the site based on a test pit analysis conducted. The infiltration basin is designed with a weir overflow, which allows a secure conveyance route to the low depression (P-CP on Figure 2). The infiltration basin provides peak flow reduction, water quality treatment (see Appendix D for Water Quality Calculations), and recharge to groundwater for the new parking area stormwater runoff. V. Calculations and Design Drainage calculations were performed on Hydrocad Stormwater Modeling System version 10.0 using Soil Conservation Service (SCS) TR-20 methodology. The SCS method is based on rainfall observations, whlch were used to develop the Intensity-Duration-Frequency relationship, or IDF curve. The mass curve is a dimensionless distribution of rainfall over time, which indicates the fraction of the rainfall event that occurs at a given time withln a 24-hour precipitation event. This synthetic distribution develops peak rates for stonns of varying duration and intensities. The SCS distribution provides a cumulative rainfall at any point in time and allows volume dependent routing runoff calculations to occur. These calculations are included in the appendices. The Berkshire Design Group, Inc. Page 3 Five Star Transportalion December 30,2011 Agawam, Massachusetts Storrnwater Drainage Report The watershed boundaries for calculation purposes are divided according to the proposed site grading and the natural limits of the drainage areas. The curve numbers (eNs) and times of concentration for the existing and proposed subcatchment areas are based on the soil type and the existing and proposed cover conditions at the site. The soil hydrologic group assumed for the site is noted in Figure 3. Watershed subcatchment areas, runoff coefficients and watercourse slopes are based on survey information. Calculations were performed for the 2-, 10-, and 100-year frequency storms under existing and proposed conditions. The results of the calculations are presented in Table I below. Appendix A presents the Hydrocad calculations. Description Depression culvert under Moylan Lane VII. Summary Table 1 Peak Flow and Volume Summary Symbol 2 year 10 year 100 year The curve number on site from existing to proposed conditions will increase from 58 to 79, however, due to the addition of a new infiltration basins, the site has been designed to maintain or reduce the peak flow rates and volumes in proposed conditions for the 2-, 10-, and 100-year storm frequencies and provides recharge and water quality treatment for the new parking area.

Five Star Transportation December 30, 2011 Agawam, Massachusetts Stormwater Drainage Report Appendix C -Proposed Stormwater Management System Operation & Plan The Berkshire Design Group, Inc. Appendix Five Star Transportation Agawam. Massachusetts Proposed Stormwater Management Plan System Operation & Maintenance During Construction December 30. 2011 The Contractor shall be responsible for inspection and maintenance during construction. At all times, siltation fabric fencing. stakes and hay bales sufficient to construct a sedimentation control barrier a minimum of 50 feet long will be stockpiled on the site in order to repair established barriers which may have been damaged or breached. An inspection of all erosion control and stormwater management systems shall be conducted by the Contractor at least once a week and during all rain storms until the completion of construction. In case of any noted breach or failure. the Contractor shall immediately make appropriate repairs to any erosion control system and notify the engineer of any problems involving stormwater management systems. A rain storm shall be defined as all or one of the following: • Any storm in which rain is predicted to last for twelve consecutive hours or more. • Any storm for which a flash flood watch or warning is issued. • Any single storm predicted to have a cumulative rainfall of greater than one- half inch. • Any storm not meeting the previous three thresholds bu1 which would mark a third consecutive day of measurable rainfall. The Contractor shall also inspect the erosion control and stormwater management systems at times of significant increase in surface water runoff due to rapid thawing when the risk of failure of erosion control measures is significant. In such instances as remedial action is necessary. the Contractor shall repair any and all significant defiCiencies in erosion control systems within two days. The Agawam DPW shall be notified of any significant failure of stormwater management systems and erosion and sediment control measures and shall be notified of any release of pollutants to a water body (stream. brook. pond. etc.). The Contractor shall remove the sediment from behind the fence of the sedimentation control barrier when the accumulated sediment has reached one- half of the original installed height of the barrier. All existing catch basins and distribution pipes shall be thoroughly cleaned of all sediment. freed from blockages and hoods shall be installed. Please see the Five Star Transportation December 30, 2011 Agawam, Massachusetts hood detail on the included site plan package. The existing drainage system must be restored to a full functioning condition. This project requires a NPDES General Permit for Stormwater Discharges from Constriction Activities. Contractor and Owner are responsible for finalizing a Stormwater Pollution Prevention Plan (SWPPP) and filing for the NDPES permit prior to the start of construction. All clearing , grading, drainage, construction, and development shall be conducted in strict accordance with the SWPPP. Post-Construction Stormwater Management System Owner: Five Star Transportation 384 Shoemaker Lane Agawam, MA 01001 Party Responsible for Operation & Maintenance: Five Star Transportation 384 Shoemaker Lane Agawam, MA 01001 Inspection & Maintenance Schedule: 1) Infiltration Basin Inspections a. Initial six months of use. Examine for stabilization and function, including determination of the duration of water standing in the basin, any sediment erosion, excessive compaction of soils, or low spots. b. Twice per year. Examine basin for the following: differential settlement, cracking, erosion, leakage, or tree growth on embankments, condition of riprap, sediment accumulation, and health of turf where applicable. Any adverse conditions noted during any inspections shall be addressed by repair or reconsideration of design components. General maintenance should include regular inspections, especially after large rainfall events. Also, document and repair any erosion issues or low spots in the spreader. Problems and repairs 'should be documented in Operations and Maintenance Log 2 Five Star Transportation December 30, 2011 Agawam, Massachusetts 2) Catch Basins Inspections Existing catch basins should be inspected at least four times per year and cleaned annually or more often if required . Oil and sediments should be removed and disposed of in accordance with local, state and federal guidelines and regulations. In the case of an oil or bulk pollutant release, the system must be cleaned immediately following the spill and the proper authorities notified . 3) Gravel Parking and Grassed Island Inspections The proposed gravel lot and associated landscaped islands shall be inspected 2 times per year for low spots that impede the intended drainage patterns, bare spots in grassed areas and gravel deposited on grassed areas from snow removal activities. Low areas that develop in the gravel lot shall be filled with trap rock gravel and compacted to reinstate the intended consistent slopes. Bare spots shall be seeded and protected with straw until vegetation has been established and gravel deposited on lawn areas shall be removed offsite or used to fill in low spots with the gravel parking area. Mowing and General Maintenance Occasional mowing (2 times per year min.) shall be performed on the side slopes and basin bottom where turf is present. Accumulated grass clippings and/or organic matter and trash and debris shall be removed. Any clogged surface areas can be loosened by deep tilling; tilled areas must be immediately revegetated . Tilling may be used in this manner for no more than two consecutive maintenance periods.
