This Order is issued under the Massachusetts Wetlands Protection Act,M.G.L. Chapter 131, Section 40 and the City of Salem Wetlands Protection Ordinance, Salem Code Chapter 34, Section 34-1 —34-13. This Order permits the construction of a go-cart track, as well as the expansion of the existing parking lot at Castle Creek Adventure Land. The expansion of the parking lot requires culverting an existing stream. According to the USGS map the stream is perennial, however, based on evidence provided by the applicant's Wetland Scientist documenting dry conditions over a period of four consecutive days, the Commission is in agreement that the stream is intermittent. Please see attached letter from Bill Manuel, Wetlands Scientist, of Wetlands and Land Management, Inc. The permitted culvert is an open box culvert, details provided on the approved plan, extending approximately 220 feet from the wooded area west of the foot bridge towards Swampscott Road, discharging into an existing culvert which flows under Swampscott Road. Two proposed man holes and catch basins have been approved and shall be maintained annually or on an as needed basis. The construction plan for installing the culvert shall be provided to the Conservation Agent at the preconstruction meeting prior to the start of construction. The plan shall outline the time frame and the order of events that will occur when installing the culvert. Specifically, the applicant shall detail how the existing and abutting resource areas will be protected throughout the duration of the project. The proposed parking lot shall be crushed stone and shall not contain additional stormwater structures. The applicant agreed to keep the existing Willow Tree located along the edge of the existing parking lot and install landscaping along the perimeter of the parking area and throughout the property where appropriate. This order permits the filling of 850 square feet of boarding vegetated wetlands to build a storage building 70' X 20'. The filling and construction is permitted so long as 1,250 square feet of wetlands is replicated on site as noted on the approved plan. Specific conditions relating to the replication are provided below and must be met prior to receiving a Certificate of Compliance. The applicant shall also obtain all necessary building permits required for development on the site. GENERAL CONDITIONS 1. This Order of Conditions must be recorded in its entirety (all 7 pages) at the Essex County Registry of Deeds or the Land Court for the district in which the land is located, after the expiration of the 10-day appeal period and within 30 days of the issuance.

Duques Conservation Agent/Staff Planner Department of Planning and Community Development 120 Washington Street Salem, MA 01970 RE: Notice of Intent for D &D Realty Trust—Castle Creek Adventure Land DEP #64-0472 Dear Ms. Duques and Conservation Commission Members: The applicant has submitted photographic evidence of the intermittent stream on site in a dry or no flow condition. This information was submitted to substantiate the intermittent status of the stream and further establish that no riverfront area is associated with this stream. As stated in the meeting and the Notice of Intent,the stream channel ceases to flow annually beginning in early summer. From summer to fall, the stream flows in response to precipitation for a short time and then ceases to flow. The applicant has provided photographic evidence of the stream on site in a dry condition for four consecutive days covering July 18, 19,20 and 21, 2008. These photographs were taken during a time when there was not a DEP drought advisory in effect. Further, these pictures were taken during the time the region was experiencing wetter than normal precipitation conditions and periodic intense afternoon rain events approaching several inches of rain. Recall as well that those Commission members in attendance at the site walk on August 26, 2008 site walk also observed the stream in a no flow condition. The applicant reports that the stream has ceased to flow on a continual basis since early June this year. 100 Conifer Hill Drive, #516, Danvers, Massachusetts 01923 Tel 978-777-0004 • Fax 978-539-0005 The regulations at 310 CMR 10.58 (2)(d)provide that: d Notwithstanding 310 CMR 10.58(2)(a)l.a. through e., the issuing authority shall fund that any stream is intermittent based upon a documented field observation that the stream is not flowing. A documented field observation shall be made by a competent source and shall be based upon an observation made at least once per day, over four days in any consecutive 12 month period, during a non-drought period on a stream not significantly affected by drawdown fom withdrawals of water supply wells, direct withdrawals, impoundments, or other man-made flow reductions or diversions. The dated photographic evidence as well as subsequent observation by the Commission requires that the Commission determine the stream to be intermittent and that no riverfront area occurs on this site.

This Order is issued under the Massachusetts Wetlands Protection Act,M.G.L. Chapter 131, Section 40 and the City of Salem Wetlands Protection Ordinance, Salem Code Chapter 34, Section 34-1 —34-13. This Order permits the construction of a go-cart track, as well as the expansion of the existing parking lot at Castle Creek Adventure Land. The expansion of the parking lot requires culverting an existing stream. According to the USGS map the stream is perennial, however, based on evidence provided by the applicant's Wetland Scientist documenting dry conditions over a period of four consecutive days,the Commission is in agreement that the stream is intermittent. Please see attached letter from Bill Manuel,Wetlands Scientist, of Wetlands and Land Management, Inc. The permitted culvert is an open box culvert, details provided on the approved plan, extending approximately 220 feet from the wooded area west of the foot bridge towards Swampscott Road, discharging into an existing culvert which flows under Swampscott Road. Two proposed man holes and catch basins have been approved and shall be maintained annually or on an as needed basis. The construction plan for installing the culvert shall be provided to the Conservation Agent at the preconstmction meeting prior to the start of construction. The plan shall outline the time frame and the order of events that will occur when installing the culvert. Specifically, the applicant shall detail how the existing and abutting resource areas will be protected throughout the duration of the project. The proposed parking lot shall be crushed stone and shall not contain additional stonnwater structures. The applicant agreed to keep the existing Willow Tree located along the edge of the existing parking lot and install landscaping along the perimeter of the parking area and throughout the property where appropriate. This order permits the filling of 850 square feet of boarding vegetated wetlands to build a storage building 70' X 20'. The filling and construction is permitted so long as 1,250 square feet of wetlands is replicated on site as noted on the approved plan. Specific conditions relating to the replication are provided below and must be met prior to receiving a Certificate of Compliance. The applicant shall also obtain all necessary building permits required for development on the site. GENERAL CONDITIONS l.

Duques Conservation Agent/StaffPlanner Department of Planning and Community Development 120 Washington Street Salem, MA 01970 RE: Notice of Intent for D&D Realty Trust—Castle Creek Adventure Land DEP 464-0472 Dear Ms. Duq ues and Conservation Commission Members: The applicant has submitted photographic evidence of the intermittent stream on site in a dry or no flow condition. This information was submitted to substantiate the intermittent status of the stream and further establish that no riverfront area is associated with this stream. As stated in the meetingh and the Notice of Intent, the stream channel ceases to flow annually beginning in early summer. From summer to fall,the stream flows in response to precipitation for a short time and then ceases to flow. The applicant has provided photographic evidence of the stream on site in a dry condition for four consecutive days covering July 18, 19, 20 and 21, 2008. These photographs were taken during a time when there was not a DEP drought advisory in effect. Further,these pictures were taken during the time the region was experiencing wetter than normal precipitation conditions and periodic intense afternoon rain events approaching several inches of rain. Recall as well that those Commission members in attendance at the site walk on August 26, 2008 site walk also observed the stream in a no flow condition. The applicant reports that the stream has ceased to flow on a continual basis since early June this year. 100 Conifer Hill Drive, #516, Danvers, Massachusetts 01923 Tel 978-777-0004 • Fax 978-539-0005 The regulations at 310 CMR 10.58 (2)(d)provide that: d. Notwithstanding 310 CUR 10.58(2)(a)L a. through c., the issuing authority shall find that any stream is intermittent based upon a documented field observation that the stream is not flowing. A documented field observation shall be made by a competent source and shall be based upon an observation made at least once per day, over four days in any consecutive 12 month period, during a non-drought period on a stream not significantly affected by drawdown from withdrawals of water supply wells, direct withdrawals, impoundments, or other man-made flow reductions or diversions. The dated photographic evidence as well as subsequent observation by the Commission requires that the Commission determine the stream to be intermittent and that no river&ont area occurs on this site.

The site is developed with a miniature golf course, parking area, and a small single story building to support the miniature golf and to sell ice cream. The site is bounded by a fitness club to the north, Swampscott Road to the east, and a wetland in the western most portion of the site. The existing gravel parking area is on the northerly side of the lot and the miniature golf area is in the southerly side of the lot. An intermittent stream bisects the site separating the existing parking area from the miniature golf portion of the site. The intermittent stream is within a steep sided gully, the sides of which appear to have been created during the initial development of the property. The two areas are connected by a foot bridge across the intermittent stream gully. The vegetated wetlands on the site were reportedly created in the past by the removal of gravel material from a portion of the site. Indeed, the vegetation within the wetland area is dominated by uniform size willow and red maple saplings. The area also exhibits typical historic disturbance in the form of random fill piles within or along the wetlands, steep side slopes approaching the wetlands, general lack of topsoil in the buffer zone and the usual accumulation of urban debris. Because of the proximity to the road and the gully shape of the intermittent stream, this particular resource area tends to accumulate a significant amount of blowing or thrown trash, and is impacted with phragmites and purple loosestrife vegetation—both indicators of a disturbed or distressed site. Wetland Resources at the Site Bordering and Isolated Vegetated Wetlands The limits of wetlands on the project site were delineated by Wetlands & Land Management Inc. Wetlands were delineated in accordance with local, Federal.and State criteria for delineating jurisdictional wetlands using methodology established in the 1987 Army Corps of Engineers Wetland Delineation Manual, and methodology outlined in the Mass. DEP manual "Delineating Bordering Vegetated Wetlands" (1995). These methods incorporate the evaluation of hydric soils, predominance of wetland vegetation and evidence of wetland hydrology. The wetlands on this site were delineated in the field using alphanumeric blue surveyors flagging. Bordering Vegetated Wetlands—A and B Series(AI to A24, BI to BII d The A and B series wetlands is a bordering wetland area separated from the remaining wetlands on the site by a distinct linear filled area. Given the age of the trees and shrubs growing on the fill, we surmised in the field that the ground disturbance likely predated current regulations and flagged the area separately. Flag Al begins at the bottom slope of the fill near the foot bridge and trends along the northerly side of the existing fill. The flags continue around additional piles of fill near flags Al to Flag A24. The B series is the opposing wetland boundary of this system and is located at the bottom of a historically filled slope, most likely during the adjacent tennis club construction Isolated Vegetated Wetlands-C Series(Cl to C42) The C series is an isolated wetland area separated from the remaining wetlands on the site by a distinct linear filled area. Given the age of the trees and shrubs growing on the fill, we surmised in the field that the ground disturbance likely predated current regulations and flagged the area separately. Flag C 1 begins at the bottom slope of the fill. The flags continue clockwise around the circular depression, following a distinct bottom of slope of the surrounding topography. Flag C42 connects to flag C 1 completing the wetland boundary. The C series was characterized as an isolated vegetated wetland, and would be not be jurisdictional under the Wetlands Protection Act, because it does not border on a stream or pond. Notwithstanding, the applicant has opted to mitigate for the loss of any wetland and will provide equal or greater wetland replication for any impacts. Inland Bank(Bank Flags 100 to117, 200 to 215) A bank is defined as the portion of the land surface, which normally abuts and confines a water body. It will occur between a water body and a vegetated bordering wetland and adjacent flood plain, or in absence of these, it occurs between a water body and an upland. On this site, the bank is associated with a drainage ditch, which bisects the property from west to east. The drainage ditch is approximately fifteen feet wide and ten feet deep however; the actual stream channel is only four feet wide and very shallow, reflecting the intermittent nature of the flow path. Other portions of bank were apparently 2 f created by the historic disturbance at the site by the placement of fill in the vicinity of the C series wetland. In the field the limits of bank resource area were delineated using blue surveyors flagging labeled 100 to 117, and 200 to 215 down gradient of the foot bridge. These flags represent each side of the drainage channel. Flags 100 and 200 begin at a culvert which facilitates water flow under Swampscott Road. The line then continues on each side of the drainage channel west across the site following a break in slope. Throughout most of the drainage channel the banks are lined with large boulders that were apparently placed there for landscaping purposes. No Riverfront Area The intermittent stream on this site is depicted on the USGS map to originate about a half mile westerly from the site. The portion of the stream relevant to this site is approximately 220 feet in length and conveys surface water from the west across the site to the east and exits the site via a culvert under Swampscott Road. Wetlands and Land Management Inc. evaluated the watercourse using the USGS StrewnStats software and determined that the watershed contributing to the intermittent stream ug gradient of the site is less than one half square mile. The predicted flow rate in the 99 percentile is less than 0.01 feet per second. Accordingly, from a regulatory presumption this steam would be considered intermittent. The property owner reports that this steam dries seasonally. According to the information presented above there is no riverfront area present on this site. Rare Species According to the October 2006 edition of the Massachusetts Natural Heritage Atlas of Estimated Habitats of Rare Wetlands Wildlife and Certified Vernal Pools, no estimated habitat of rare wetlands wildlife or certified vernal pools are shown to exist on or near the subject parcel. 3 Attachment A Project Description f Proposed Work Discussion of Proposed Work Property Located at: 100 to 114 Swampscott Road, Salem Introduction The proposed work associated with this application involves the construction of a paved go-cart track, construction of a small building to store the carts, and the expansion of the existing crushed stone parking lot. Portions of the proposed work will result in alteration of vegetated wetlands, as well as bank resource area. A wetland replication plan is included with this application. Discussion of Proposed Work The proposed work will consist of three components: construction of the go-cart track, construction of the storage building, and parking lot expansion. Each component will be discussed in detail below. Go-Cart Track The proposed track will be located in the southernmost portion of the site. This area is currently overgrown with various opportunistic shrubs and grasses. Installation of the proposed erosion controls will be the first step in the construction process. The erosion control barrier will not only limit the migration of sediment into adjacent resource areas, but also provide a visual reminder of the limit of work. The location of the erosion controls is indicated on the site plan. The_Commission-may_.also want to-stipulate the use of plastic orange construction-fencing as a secondary demarcation of the'allowed`work areas-The orange fencing will not only serve as an easily identifiable limit of work,;but,also will further minimize the potential for construction debris to blow from the work area. Once the erosion controls are installed the next-.step in the construction process will be to clear and grub the area. Vegetation and other debris will be cleared and lo#ded into dumpsters for dispos,il off site. A portion of the track construction will require filling in approximately 850 square feet of the adjacent wetland resource area in order to construct a retaining wall and bring the surrounding area to a uniform grade. (A replication plan has been included in this application). Once the site has been cleared, underground utilities will be installed and the area will be rough graded. A layer of crushed stone and gravel will then be placed as a base for the track prior to paving. All equipment will be parked outside of the buffer zone overnight. The next step in track construction will be to apply a layer of bituminous concrete over the base layer followed by a top coat of pavement. Following construction, any disturbed areas will be loamed and seeded or landscaped. Storage Building The storage building will be constructed in the location depicted on the site plan. This g g P structure will be used to store the go-carts when not in use. Excavating equipment is used for construction of the new building. During the initial excavation, soil will be carefully excavated to pour foundation walls and associated footings. Soil will be side cast into the interior of the foundation area instead of along the outer perimeter of the trench. In this manner, the foundation trenches function as sediment traps between the wetlands and the excavated soils. Careful excavation and oversight is intended to avoid any unintended discharge or fall back of material into the adjacent resource area. Any excess or additional soil that cannot be stockpiled within the interior of the foundation walls will be stored away from the excavation, away from the buffer zone slope above the wetlands, and returned as necessary to backfill. This building will be constructed on a slab on grade instead of a typical foundation. The goal of utilizing a slab on grade for this project was to minimize the amount of material that was to be excavated. Forms are set up and the footings and walls are poured with concrete. After a short period to allow the concrete to cure, the forms are stripped off and the walls are backfilled. Material for the building construction will be dropped in the existing crushed stone drive. A small bobcat type machine may be used to deliver building materials to the immediate work site. Dumpsters should be on site for rubbish control during construction. Once the construction is complete, final site landscaping will occur. Disturbed areas will be loamed and seeded or landscaped. Parking Lot/Drainage Pipe Installation The proposed parking lot expansion will take place over an area that is currently a drainage ditch. The ditch is approximately fifteen feet deep and twenty feet wide. There 2 is an intermittent steam located at the bottom of the ditch with seasonal surface water flow. The first step prior to parking lot construction will be to install a concrete pipe which will provide an uninterrupted flow path for the intermittent stream. Th�ipe will extend ip--p—roximately 220 feet from the wooded area west of the foot bridge across the site, and discharge into an existing culvert which flows under Swampscott Road. Installation of— e amage pipe will require either work in the dry condition or a temporary pump- around of the intermittent stream. Sand bag dams will prevent the stream from flowing into the work zone. The work will commence in the lowest portion of the site and progress up slope. In this manner,the sand bag dams can be removed at the end of each work day and the stream can continue to flow through the newly installed pipe until the next work day. Following construction, the stream will be redirected back into the newly installed drainage pipe Following installation of the pipe,the site will be graded to match the existing grades on the site and gravel parking area will be constructed as shown on the site plan. After the area has been brought to a uniform grade, a layer of crushed stone will be spread over the proposed parking area. Following all construction any disturbed areas will be loamed and seeded or landscaped. Stormwater Management This project is subject to the DEP Stormwater Management Policy. The stormwater management on this site will attenuate the difference between the predevelopment and post development stormwater flow rates using an exfiltration system. (See attached Stormwater Management Report by Scott Patrowicz P.E.) 3 Evaluation of Wetland Resource Area Impacts Evaluation of Wetland Resource Area Impacts Discussion of Wetland Resource Areas and Potential Impacts Property Located at: 100 to 114 Swampscott Road, Salem Introduction The following is intended to address the planned as well as potential impacts to the wetland resource areas associated with the proposed work at Castle Creek Adventure Land. Isolated Vegetated Wetlands Portions of the proposed work on this site will result in a loss of approximately 850 square feet of vegetated wetlands. The majority of the work will be in buffer zone only. For the work which will be in buffer zone only the appropriate erosion controls will be installed as indicated on the permit plan. The erosion controls shall serve to arrest overland travel of sediment during rain events, and also serve as a visual barrier and physical determination of the limit of work. The siltation barriers will remain in place until the proposed lawn and landscaping is well established. The following will address the proposed work that will directly affect the vegetated wetlands on the site. For the purpose of this evaluation, the performance standards of bordering vegetated wetlands at 310 CMR 10.55 are applied to this project to evaluate the• potential.work in relation to Wetlands Protection Act performance standards. Performance Standards Regarding Bordering Vegetated Wetlands Alteration According to 310 CMR 10:55,section 4(b), the issuing authority may issue an Order of ;Conditions permitting work which results in a loss of up to 5000 square feet of Bordering �pgetated Wetland when said area is replaced with the following general conditions and any additional,specific conditions the issuing authority deems necessary to ensure that the replacement area will function in a manner similar to the area that will be lost. This project has been designed to reduce the impact to the wetland resource areas to the greatest extent possible; however the scope of the proposed work requires minor wetland alteration to be performed 10:55 (4)(b)(1) Per regulations, the surface of the replacement area to be created shall be equal to that of the area that will be lost. The proposed work will result in 850 square feet of wetland loss. The proposed replication area will be approximately 1,250 square feet. The replication will result in an increase of approximately 400 square feet of surface area. 10:55 (4)(b)(2) Per regulations, the groundwater and surface elevation of the replacement area shall be equivalent to that of the lost area. The proposed replication area will be located approximately 150 feet from the altered area; however the replication area will be at the same general elevation as the lost area. 10:55 (4)(b)(3) Per regulations, the overall horizontal configuration and location of the replacement area with respect to the bank will be similar to that of the lost area. The configuration and location of the replacement area will be located on the same body of water, as well as the same relative position in the landscape. Both areas are located on the edge of the wetland boundary; as such they will remain similar with respect to horizontal configuration. 10:55 (4)(b)(4) Per regulations, the replacement area shall have an unrestricted hydraulic connection to the same water body or waterway associated with the lost area. The replication area will provide an unrestricted hydraulic connection to the surrounding wetland area. 10:55 (4)(b)(5) Per regulations, the replacement area shall be located within the same general area of the water body or reach of the water body as the lost area. 2 The permanent wetland replication area is approximately 150 feet from the potential permanent impact area. The location of the proposed replication area will be within the same reach of lost area. 10:55 (4)(b)(6) Per regulations at least 75% of the surface of the replacement areas shall be reestablished with indigenous wetland plant species within two growing seasons, and prior to said vegetation reestablishment any exposed soil in the replacement area shall be stabilized to prevent erosion in accordance with standard U.S. Conservation Service methods. The Wetland Replication Plan attached to this application states that all vegetation will be replaced with indigenous vegetation. The permanent replication area will also provide 75%coverage within the second growing season. The foregoing is intended to address the Regulatory Performance Standards and the expressed interests of the Wetlands Protection Act by mitigating impacted wetland resource area followed by active re-vegetation in the same location, thereby providing a function similar to the lost area. Inland Bank The bank resource area on this site consists of the sides of a man-made drainage ditch. The ditch carries seasonal surface water flow through the site to a larger wetland system on the opposite side of Swampscott Road. The proposed work will involve replacing the existing drainage channel with a concrete pipe, and installing fill over the pipe. The proposed work will result in a loss of approximately 180 linear feet of bank resource area. The proposed work is part of a larger site maintenance project. Because the site is located in an urbanized area, trash annually accumulates in the drainage ditch and flows into a larger wetland on the opposite side of Swampscott Road. One of the project's objectives was to eliminate the accumulation of trash in the ditch which will result in an overall cleaner site, as well as improve the water quality in the down gradient wetland. Below is a discussion of the performance standards relevant to the proposed work and bank resource area. Performance Standards Regarding Work On or In Close Proximity to a Bank According to 310 CMR 10:54 section(4), any proposed work on a bank shall not impair the following: 3 10:54(4)(a)(1)Physical Stability of the Bank The bank on this site will be replaced by a reinforced concrete pipe; as such the stability of the bank will not be adversely affected. 10:54 (4)(a)(2) The Water Carrying Capacity of the Existing Channel Within the Bank The current pipe size under Swampscott Road will be extended upgradient. As such the water carrying capacity of the channel will remain the same. 10:54 (4)(a)(3) Ground Water and Surface Water Quality The ground water and surface water quality could be construed to be an improvement over the present conditions. By constructing a "closed pipe system" there is less chance for contaminants such as trash and other debris to enter the channel and eventually enter the wetland down gradient of the site. 10:54 (4)(a)(4) The Capacity of the Bank to Provide Breeding Habitat, Escape, Cover and Food for Fisheries The present bank provides little wildlife habitat value (See the attached Bank Wildlife Habitat Evaluation) 10:54 (4)(a)(5) The Capacity of the Bank to Provide Important Wildlife Functions Per regulations a project or projects on a single lot, for which Notice(s) of Intent is filed on or after November 1, 1987,that (cumulatively) alter(s) up to 10%or 50 feet (whichever is less) of the length of the bank found to be significant to the protection of wildlife habitat, shall not be deemed to impair its capacity to provide important wildlife functions. The proposed work exceeds the threshold of wildlife habitat value, however an evaluation of the impacted banks reveals that portions of these banks are armored, or are poorly defined or non-existent. Wetlands and Land Management Inc has performed a wildlife habitat evaluation for the bank resource area on this site(included in this report). The study determined that the bank resource area on this site does not provide the above mentioned functions as discussed in the attached wildlife habitat evaluation. As this bank is associated with an intermittent drainage ditch, fisheries habitat does not apply. 4 Wetland Replication Methodology Wetland Replication Plan Castle Creek Adventure Land 100 to 114 Swampscott Road Salem, Massachusetts November 2007 Wetlands & Land Management, Inc. 100 Conifer Hill Drive-Suite 516 Danvers, MA 01923 Wetland Replication Plan 100 Swampscott Road, Salem Introduction and Site Description The proposed work associated with this application involves the construction of a paved go-cart track, construction of a small building to store the carts, and the expansion of the existing crushed stone parking lot. The intent of the replication plan will be to create 1,250 square feet of shrub swamp wetland to mitigate for the loss of 850+/- square feet of wetland affected by proposed construction at the Swampscott Road property. The performance standards at 310 (CMR 10.55(4)) are applied to this project despite the fact that the impacted wetland area is isolated and non jurisdictional pursuant to the above regulations. Notwithstanding, other regulatory agencies would require replication of isolated wetlands in order to comply with the terms and conditions of appropriate general permits such as the ACOE Programmatic General Permit. The following methodology is proposed to fulfill wetland replication requirements for the proposed wetland impact area at the 100 to 114 Swampscott Road property. The limits of vegetated wetlands on the project site were delineated by Wetlands&Land Management Inc. Wetlands were delineated in accordance with local, Federal and State criteria for delineating jurisdictional wetlands using methodology established in the 1987 Army Corps of Engineers Wetland Delineation Manual, and methodology outlined in the Mass. DEP manual "Delineating Bordering Vegetated Wetlands" (1995). These methods incorporate the evaluation of hydric soils, predominance of wetland vegetation and evidence of wetland hydrology. Proposed Construction, Wetland Impacts and Replication Construction of the retaining wall and go-cart track will impact wetlands at flags C23 to C29. Replication was selected in the vicinity of flags C8 to C15. Wetland replication will provide approximately 1,250 square feet of replication to mitigate of the loss of approximately 850 square feat. The replication area was selected to provide a single suitable wetland restoration site for the entire impacted area. The selected site meets the performance standards established under 310 CMR 10.54. Specifically, the surface of the replacement area will be at least equal (and exceeds) the lost area; the groundwater or surface water of the replacement area shall be approximately / equal to the lost area; the overall configuration and location of the replacement area with respect I to the wetlands is similar to the lost area; the replacement area will have an unrestricted 1 connection to the same waterway as the lost area;the replacement area will be located in the �Y same general area as the lost area and the planting schedule will provide for 75% coverage with wetland vegetation within two growing seasons or less. «j The replication area should be constructed and monitored in accordance with the following. • The areas to be disturbed shall be isolated from adjacent wetlands by a staked erosion control barrier. When installing erosion controls, cut interfering vegetation at grade, leaving the root system intact. Upon removal of the erosion controls, this type of cutting encourages prolific shoots from the pruned vegetation and should provide for rapid restoration of the temporarily disturbed area. Further, existing herbaceous seed and rootstock should regenerate the herbaceous cover within a growing season or less. • Stake the limits of the grading and the wetland replication grading. Clear and grub the area for wetland replication first. The wetland replication area subgrade should be prepared and ready to receive organic soils and plants from the impacted area prior to disturbance of the existing wetland areas. Material shall be grubbed from the replication area to a depth twelve inches below proposed finish grade and stockpiled. The subgrade of the replication area should be inspected wetland scientist for proper interface with the seasonal groundwater table prior to installing any topsoil or vegetation. • To the extent possible, organic soils and plant stock shall be removed from the resource areas to be filled and transferred directly to the replication area. To transplant woody shrubs, the preferred method is to excavate the shrub, roots and surrounding soil with an excavator and move the entire mass to the replication area in one large segment. • Fill gaps in the replication area first with salvaged stockpiled topsoil and organic material and secondly with quality topsoil either from on site or brought from off site sources. Imported topsoil should be augmented with leaf compost so the final content is 50% leaf mulch and 50% mineral soil. • The final surface of the replication area should be augmented with 2-5% coverage of coarse woody debris such as logs in various states of decomposition. Monitoring Monitoring the progress of the replication area is integral to the success of the replication effort. CPO following construction oversight and monitoring schedule is recommended. A wetland professional should oversee the construction and future inspections. Schedule Object ve Pre-Construction: Meet with contractor-to establish timing, objective and methods. Re-establish wetland flags as necessary. During Construction: Oversee replication area preparation including establishment of the sub-grade elevation, preparation of suitable depth of subsoil, transfer of soils and vegetation from the impacted area to the restoration area, creation of micro topography, installation of nursery stock and final grading, mulching and site clean-up. Post Construction: One month after installation to assess transplant and nursery stock plant survivability. Provide written report to the Conservation Commission. Establish photo stations to be used during future evaluations. On-Going monitoring End of the first growing season. Report on progress of the re-vegetation, area coverage of wetland species, apparent hydrology, provide photos, assess plant volunteering from the adjacent wetland, assess invasive species within replication area. Provide assessment of the likelihood of achieving 75% wetland plant coverage within one additional growing season. Institute a contingency plan that could include additional nursery stock installation to achieve regulatory compliance. September of the second growing season to provide similar assessment as in the first growing season. Assess the likelihood of obtaining a Certificate of Compliance; institute a contingency plan to achieve regulatory compliance by the end of the second growing season. Siltation Control and Final Cleanup The siltation barrier between the replication area and the adjacent wetland shall remain in place only until new growth is sufficient to stabilize the surface. The barrier between wetland and replication area shall then be remove in order to allow free passage of surface water between the newly graded and the adjacent wetland. The siltation barrier between the replicated wetland and the adjacent upland shall remain in place until the cessation of construction and the approval of the Conservation Commission. The foregoing is intended to address the Regulatory Performance Standards and the expressed interests of the Wetlands Protection Act by direct transfer of impacted resource area soils to a replication area followed by active re-vegetation in a replication area with similar topography and hydrology, within the same wetlands reach and providing a function similar to the lost area. Wetland Restoration Methodology for Unintended Temporary Wedand Impacts The project does not intend to intentionally alter more wetland resources than accounted for above, however; the work is in close proximity to the resource area near flags C19 to C21. During excavation, some unintended excavated material fall back may occur, or a grubbed root mass may disturb soil under the silt fence. During the construction process, construction personnel will need to stage ladders on the westerly side of the building. As foot traffic and/or inadvertent spilling of material would be considered"alteration"the application includes a wetland restoration plan to address any potential alteration. The project anticipates the extent of alteration could be approximately 160 square feet+/- in this area. To prevent or immediately mitigate for any impacted wetland resource area,the application proposes the following work protocol. The following protocol provides for an on-site monitor during the excavation portion of the project and periodic visits during construction. The protocol stipulates a procedure to immediately restore any wetlands, and provides reporting and follow-up requirements to ensure any unintended wetland impacts are immediately mitigated. The application provides for 160 square feet of wetland replication in place near flags C 19 to C21. The applicant is confident that the project can be completed with zero additional impacts or minor temporary wetland impacts however if the Commission should warrant, a methodology is included for restoration of any unintended wetland impacts in this limited area. Consider the following: 1. Provide an On Site Monitor During Excavation During clearing and excavation, an erosion control monitor will be on site. The site monitor will oversee the excavation process and direct repairs of erosion controls as necessary. 2. Immediately Remove Any Material That falls into the Resource Area Any material inadvertently spilled into the resource area will be removed immediately by hand tools. 3. Notify Conservation Agent In the event that the resource area is adversely affected,the Conservation Commission agent will be notified immediately to consult, and/or coordinate restoration efforts. 4. Initiate Contingency Plan If resource area alteration occurs,the applicant shall replace any vegetation that has been damaged, and/or removed during the construction process. Any damaged species will be replaced with the same plant species in a 1:1 ratio. 5. Monitor Replication Area for Two Growing Seasons All of the species that have been replaced will be monitored for two growing seasons. To ensure success of the replaced vegetation, qualified personnel will visit the site at regular intervals to monitor the progress of the replication area. f Appendix A— Planting Schedule Wetland Replication Summary and Plantinla Schedule 100 Swampscott Road Wetland Impacts Wetland Impact I Arid ation 850+1- square feet of permanent wetland impact from road Create 1,250 square feet of new forested wetland(in excess of construction 1:1 ratio of the impacted area Area Square Feet Plants Size Spacing Replication Area— Provide 1,250 square 15 each of red maple 2-3 feet Evenly throughout the Final grade of feet (Acer rubrum), grey replication area replication area will be birch (Betula determined in the field. populifolia) and willow Roughly elevation 53 (Salix sp) 2-3 feet Evenly throughout the 15 each of arrowwood replication area (Viburnam dentatum), and high bush blueberry (Vaccinium co mbosum Per suppliers New England WetMix specifications (or approved equal)** ** -New England Wetlands Plants, Amherst, MA 413-548-8000 Wildlife Habitat Evaluation Wildlife Habitat Evaluation Prepared for: D & D Realty Trust For Property at 100 to 114 Swampscott Road, Salem November 2007 Wetlands & Land Management, Inc. 100 Conifer Hill Drive — Suite 516 Danvers, MA 01923 Wildlife Habitat Evaluation 100 to 114 Swampscott Road, Salem, MA D& D Realty Trust has filed a Notice of Intent to construct a new parking area over an area that contains intermittent stream bank resource area. The proposed road work impacts approximately 180 linear feet of intermittent stream bank. Wetlands& Land Management, Inc. has prepared a wildlife habitat evaluation in accordance with 310 CMR 10.60. The wildlife habitat evaluation will evaluate the impacts to the site bank habitat and evaluate whether the exceedence of thresholds established at 310 CMR 10.54 (4)(a)(5) substantially reduce the site capacity to provide important wildlife habitat functions listed in 310 CMR 10.60(2)(a). Introduction The subject property is located at 100 to 114 Swampscott Road,the Castle Creek Adventure Land in Salem. The site is developed with a miniature golf course, parking area, and a small single story building to support the miniature golf and to sell ice cream. The site is bounded by a fitness club to the north, Swampscott Road to the east, and a wetland in the western most portion of the site. The existing gravel parking area is on the northerly side of the lot and the miniature golf area is in the southerly side of the lot. An intermittent stream bisects the site separating the existing parking area from the miniature golf portion of the site. The intermittent stream is within a steep sided gully, the sides of which appear to have been created during the initial development of the property. The two areas are connected by a foot bridge across the intermittent stream gully. Wetlands&Land Management, Inc. has previously visited the site and performed a delineation of the vegetated wetland and bank resource areas at the site. Five series of wetland flags were placed on the ground to delineate wetland resource areas including intermittent stream bank systems at or adjacent to the property. The vegetated wetlands on the site can be generally described as an isolated depression wetland system that were apparently created by historic gravel removal or earth moving activity on the site. Gullies on the site within which the intermittent stream flows has also been reportedly created or enhanced through the development of the site. A complete description of the existing wetland and intermittent stream systems are included in the Wetland Resource Inventory section of this application. 2 f Site vegetation Most of the site is developed with the miniature golf course and parking area for the business. An upland buffer zone area is found on the southerly extreme of the site. This is the area of the proposed go-cart track and support building. The vegetated wetlands are located on the westerly extreme of the site in a depression area. The vegetated wetlands on the site were reportedly created in the past by the removal of gravel material from a portion of the site. Wetland vegetation was primarily scrub/shrub wetlands dominated by uniform size willow and red maple saplings, willow and glossy buckthorn shrubs and common herbaceous wetland plants including various fems and sedges. The area also exhibits typical historic disturbance in the form of random fill piles within or along the wetlands, steep side slopes approaching the wetlands, general lack of topsoil in the buffer zone and the usual accumulation of urban debris. Vegetation within the steep gully bisecting the property is primarily planted juniper bushes along the buffer area side slopes. Closer to Swampscott Road, we noted the growth of phragmites and purple loosestrife, both indicators of degraded water quality, most likely from the proximity to the road. Topography and Soils Topography across the site is variable owing to past and recent site development. The parking area to the north is level or sloping towards Swampscott Road. The southerly side of the site is the highest areas on the site and is variable due to the presence of the multi-level playing surface of the miniature golf course. The intermittent stream gully is approximately 10 to 15 feet lower than the adjacent parking area and miniature golf course. The Natural Resource Conservation Service has mapped the soils on the site and the general region as Chatfield-Hollis Rock Outcrop Complex in the upland areas. These soils are derived from glacial till over granitic bedrock. The till layers can be thick in places throughout this unit, but bedrock outcrops are common. The soils are generally sandy texture with moderate permeability. The on-site evaluations concur with NRCS mapping. The smaller interior wetland systems are inclusions in the Chatfield—Hollis system that were too small to be mapped as a separate unit. (Typically, the smallest mapping unit is five acres for NRCS mapping.) Intermittent Stream Bank and Vegetated Wetlands Intermittent stream bank is found essentially bisecting the site. Stream bank is located within the A and B wetlands and at the down gradient end of the A and B wetland systems, identified in the field with flags 100 to 117 and 200 to 215. The area of intermittent stream impact is associated with the 100 and 200 series intermittent stream flags down gradient of the foot bridge over the stream. 3 r The total length of bank resource area on the property is determined to be 340 linear feet. The proposed parking lot improvements will impact approximately 180 linear feet of bank. The alteration of 180 linear feet of bank resource area exceeds the 10% or 50 linear feet (which ever is less) impact threshold established under 310 CMR 10.54. Accordingly this wildlife habitat evaluation is prepared to determine if the project as proposed has an impact on the ability of the site to provide important bank wildlife habitat functions. Wildlife Habitat Assessment With respect to potential bank wildlife habitat functions, I conclude the portion of lost bank provides limited, if any, important wildlife habitat functions. I conclude this based on my original characterization and delineation of this resource area, subsequent visits to the site, observations and measurements of the bank characteristics and professional judgment. Description of Bank Conditions The area of study begins at the topographic low point of the bank system at flags 100 and 200. The entire length of this intermittent stream is found within an excavated gully. At this point,the intermittent stream enters a culvert under Swampscott Road. Here,the intermittent stream appears to be a historically excavated channel or at least enhanced. The channel has a variable flow path over most of the length the intermittent stream in this area. The flow path at any instance is apparently dependant on any debris or accumulated vegetation within the channel. The flow path appears to "meander" across the bottom of the gully in several locations and the delineation reflects the widest extent of historical flow observed based on scouring, debris and leaf dams, etc. The entire northerly side of the flow path was armored with large boulders. The southerly side of the bank had occasional boulders. Where not reinforced with boulders, the actual banks were poorly formed, very shallow features perhaps only a few inches high. Vegetation within the flow path of the intermittent stream consisted primarily of phragmites and purple loosestrife, with a few opportunistic shrubs along the length of the study area. Adjacent buffer zone vegetation was almost entirely planted landscaping junipers. The intermittent stream system begins on the upgradient side at flag 117/215 at approximately elevation 51. The terminus of the system at flag 100 is at approximately 41.6. The gradient of the stream is steepest between flags 112 and 117, dropping nearly six feet in elevation over roughly 55 linear feet or a roughly 11% slope. The stream gradient flattens along the remaining portion of the resource area, with stream gradient flattening to roughly 2% slope. The change in gradient is proportional to the width of the flow path. The steeper gradient has the most narrow flow path. The lower gradient has the widest flow path, but poorly formed or non-existent banks. 4 f Soils observed directly within the channel consisted or a friable to firm fine sandy loam with a stony substrate. I noted a lack of accumulation of organic material within the stream channel, likely owing to the relatively steep gradient in the initial reach of the stream. The portion of bank area to be lost is 180 linear feet, extending from flag 1 to roughly flag 114 (flags 200 to 211 on the opposite side of the stream. This area would include the area impacted by phragmites and loosestrife growth, the lowest gradient and area of poorly formed bank and the area that accumulates the most trash due to the proximity to the adjacent road. Approximately 160 linear feet of bank in this system remains undisturbed. Assessment of Bank Characteristics 310 CMR 10.54(1) establishes that banks because of their topography, plant community composition, soil composition and structure may provide wildlife habitat functions. After evaluation of the nature and physical features of this bank resource area, I conclude the area of bank impact does not adversely affect any of these wildlife habitat functions because of the poorly formed or non-existent bank structure. Much of the bank resource area is a shallow channel, only a few inches deep, lacking any distinct topographic features. No portions of the bank provide entrenched vertical sides that may offer burrowing or hibernation opportunities. The soil profile in the bank resource area lacked significant accumulation of detritus and organic material, which is necessary to provide a food source, shelter, or over wintering habitat for amphibians and invertebrates. The lack of sustained hydrology in the bank resource area does not provide the sustained aquatic habitat, cover and nesting areas required by water dependant amphibians, mammals and reptiles. Accordingly, it is reasonable to conclude the lost bank does not provide any significant food, cover or breeding functions for wetlands wildlife. Summary of the Bank Habitat Evaluation The project involves construction of a new parking area that will impact 180linear feet of intermittent stream bank. The project exceeded the threshold for which a habitat evaluation was required. This evaluation concludes that the impacted area does not provide important bank wildlife habitat functions such as shelter, over wintering, burrowing and breeding and nesting in a significant manner. 5 I CITY OF SALEM CONSE RVATION COMMISSION March 11,2011 David and Dana Dilisio D & D Realty Trust 100 Swampscott Rd.

One pole is located outside buffer zone area ad would not require any additional oversight from the DEP or the Conservation Commission. The second pole is located directly adjacent to the travels way at the intersection of Swampscott Road the the adjacent Robinson Road. This pole location is within buffer zone to wetlands on the opposite side of Swampscott Road. We didn't look at this are specifically, but you might remember a phragmites wetland on the opposite side of Swampscott Road. Typical pole installation involves the utility truck staging at the pole location. The truck will most likely operate four the pavement as in this case the pole location is directly adjacent to the roadway. The utility truck has a large boring auger attached to the truck and a pole installation hole is augured into the ground. The new pole is placed in the augered hole and the hole is backfilled with spoils that were augured out of the hole. The work is down gradient of the wetlands on the site, and separated by the width of Swampscott Road from the phragmites wetlands on the other side of Swampscott Road. I would suggest that the one pole installation in buffer zone could be allowed as a minor amendment to the approved plan as the new impact area is limited to a bored hole about 18 inches in diameter. The applicant is anxious to proceed and avoid delays in opening the grounds for the summer season. Would you please concur that this one pole installation can proceed without further permitting?

MassDEP shall assume jurisdiction over this project and will make a determination as to whether the area on which the proposed work is to be done is significant to the statutory interests identified in the Act. It is MassDEP's opinion that the project and the OOC do not contribute to the protection of the interests identified in the Act, and that the OOC is inconsistent with the Act's regulations, 310 CMR 10.00. MassDEP's specific concerns regarding the project proposal and the OOC are based upon the plan, information submitted in the Notice of Intent (NOI) and the subsequent OOC issued by the Conservation Commission and include but are not limited to: the inability of the project to comply with the Performance Standards for 310 CMR 10.54 (4), specifically in the location of the existing daylighted stream that is proposed to be routed through an underground culvert. In preparation of a Superseding Order of Conditions (SOC), MassDEP will conduct a site visit with you and all concerned parties. The purpose of this visit will be to confirm that the area is significant to the interests of the Act, and to informally discuss those issues relevant to this appeal.

MassDEP has made the following findings and has determined that,based on information presently in the record,the permit will either be denied or conditions imposed that would significantly modify or restrict operation of the project or activity as proposed. As a result of observations made at the November 13, 2008 site inspection, MassDEP has determined that the proposal to culvert approximately 180 linear feet of the intermittent stream running through the site does not meet the performance standards in the Wetlands Protection Act Regulations (the Regulations) at 310 CMR 10.54, because it would impair the following interests associated with Bank: 1) The water carrying capacity of the existing channel within the Bank: The proposed 180 linear foot box culvert contains a concrete top and sides and an open crushed stone bottom. This design varies significantly from the current natural stream channel that contains a mixed substrate with dense vegetation. It is our opinion that the water carrying capacity of the stream will be changed from the existing capacity once the stream flow is directed into the concrete surface and crushed stone base of the culvert compared with the more diverse elements of the existing natural channel. 2) The capacity of the Bank to provide important wildlife habitat functions: The topography, soil structure, and plant community composition and structure of the Bank, even areas that maybe classified as poorly formed, can provide food, shelter and migratory and breeding areas for wildlife of far greater quality than that of the proposed closed culvert. In addition, the 5 large trees that are proposed to be removed in the 100- This information is available in alternate format Call Donald M.Games,ADA Coordinator at 617-556-1057.Too#866-539-7622 or 617-574-6868. http://"w .mass.gov/dep•Fax(978)694-3499 Printed on Recycled Paper foot buffer zone associated with the Bank provide, at a minimum, shade and breeding habitat. Please note that, as proposed, this project requires submission of a Detailed Wildlife Habitat Evaluation. Under the Massachusetts Wildlife Habitat Protection Guidance for Inland Wetlands, March 2006, at Appendix A, regarding Simplified Wildlife Habitat Evaluation, activities in Bank, when proposed alterations are more than twice the size of thresholds (as is the case with the proposed project), applicants should complete a Detailed Wildlife Habitat Evaluation (Appendix B). Given that MassDEP is requesting an alternative design to the 180 linear foot closed culvert, submission of a Detailed Wildlife Habitat Evaluation (Appendix B) is not requested at this time. The following additional information described below is necessary for MassDEP to complete its review: 1. Revised plans prepared and stamped by a registered engineer, showing an alternative design that does not alter the stream and streambank. 2. An evaluation as to whether the area shown as Wetland Area C qualifies as Isolated Land Subject to Flooding (ILSF) [SEE:310 CMR 10.57 (2) (b)]. Further guidance regarding the definition of ILSF is found in Wetlands Program Policy 85-2 as revised March 1, 1995. The submission should include an opinion certified by a registered professional engineer, supported by engineering calculations, regarding the extent of the ILSF boundary, as specified in the Regulations and Guidance. In accordance with the Regulations, at 310 CMR 10.05(7)(f) 2, additional information must be submitted within 70 days of this.request. Copies of all information submitted to DEP must at the same time be sent to all concerned parties.

This information was submitted to substantiate the intermittent status of the stream and further establish that no riverfront area is associated with this stream. As stated in the meeting and the Notice of Intent,the stream channel ceases to flow annually beginning in early summer. From summer to fall,the stream flows in response to precipitation for a short time and then ceases to flow. The applicant has provided photographic evidence of the stream on site in a dry condition for four consecutive days covering July 18, 19, 20 and 21, 2008. These photographs were taken during a time when there was not a DEP drought advisory in effect. Further, these pictures were taken during the time the region was experiencing wetter than normal precipitation conditions and periodic intense afternoon rain events approaching several inches of rain. Recall as well that those Commission members in attendance at the site walk on August 26, 2008 site walk also observed the stream in a no flow condition. The applicant reports that the stream has ceased to flow on a continual basis since early June this year. 100 Conifer Hill Drive, #516, Danvers, Massachusetts 01923 Tel 978-777-0004 •Fax 978-539-0005 The regulations at 310 CMR 10.58 (2)(d)provide that: d. Notwithstanding 310 CMR 10.58(2)(a)La. through c., the issuing authority shall find that any stream is intermittent based upon a documented field observation that the stream is not flowing. A documented field observation shall be made by a competent source and shall be based upon an observation made at least once per day, over four days in any consecutive 12 month period, during a non-drought period on a stream not significantly affected by drawdown from withdrawals of water supply wells, direct withdrawals, impoundments, or other man-made flow reductions or diversions. The dated photographic evidence as well as subsequent observation by the Commission requires that the Commission determine the stream to be intermittent and that no riverfront area occurs on this site.

INTRODUCTION Locus is at#100 to#114 Swampscott Road, Salem, MA (assessor's map 7, lot 61 and formally lot 85). The site is currently used as a miniature golf course with associated parking and buildings (as shown on the attached photographs). The existing parking is crushed stone. The existing conditions, topography, property line and wetland flags have been field surveyed by Mr. Chuck Faia (Parsons and Faia, Inc.). The wetland resource areas on the site have been identified by Mr. Bill Manual (Wetlands and Land Management, Inc.). The proposed development of the site includes the culverting of the existing intermittent stream, replicating wetlands (discussed.by Bill Manual under separate cover submitted with the Notice of Intent application), construction of a storage building, an expanded crushed stone parking lot and a new paved go-cart track. The proposed Site Plan has been prepared by Parsons and Faia, Inc. (attached under separate cover submitted with the Notice of Intent application). The purpose of this report is to specifically engineer a stormwater management system that will mitigate impacts of the new parking lot expansion and the newly paved go-cart track proposed on the site with the use of BMP's so that runoff is controlled on-site, thus minimizing off-site impacts. The stormwater management plan, including the use of multiple and sequential "Best Management Practices" (BMP's)for controlling water quality and quantity of runoff, was engineered to meet those standards set forth in DEP's Stormwater Management Handbooks (Volumes One and Two, issued by DEP/CZM, March, 1997). 2. EXISTING (PRE-DEVELOPMENT) CONDITIONS a. SOILS The soils of the site were mapped by SCS (Soil Conservation Service) as shown in the Essex County Soil Survey(refer to Appendix#1 for the map and soil descriptions). The site's soils are characterized as Charlton series (CrC). These soils are classified by SCS (Table 16) as Hydrologic Soil Group "B"with a high water table greater than 6-feet deep and are suitable for an on-site exfiltration system. Additionally, the soils were tested by Parsons and Faia, Inc. on 10/30/07. Soil logs are shown on the survey plan. The soils found are generally described as boney-gravel, gravel and silty gravel with no groundwater and no ledge found to 96" (DH#1 thru DH#3). A Percolation test was also performed with a 3 MPI percolation rate. This soil testing is consistent with the permeability rate given by SCS (Table 15)for 0.6 to 6.0 inches per hour. b. VEGETATION Presently on-site, in the area of the proposed go-cart track(located to the south of the existing mini-golf course), there is an existing maintained lawn and some scrubby vegetation (as shown on the existing conditions plan and site photos). In the area of the proposed parking lot expansion (located to the north of the existing mini-golf course) is a swale depression and intermittent stream. The vegetation in this area is described by Wetlands and Land Management, Inc. (under separate cover submitted with the Notice of Intent application). c. TOPOGRAPHY Existing conditions and topography are shown on the survey plan prepared by Parsons and Faia, Inc. Generally, the site of the proposed go-cart slopes to the east towards Robinson Road and Swampscott Road. In the area of the proposed parking lot expansion, the site is a swale depression (sloping towards the existing 24-inch culvert crossing Swampscott Road). d. BOUNDARIES OF WETLAND RESOURCE AREAS There are wetland resource areas at the project site. The project site is also within the 100-foot wetlands buffer zone. e.

PROPOSED (POST-DEVELOPMENT) CONDITIONS a. GENERAL DESCRIPTION OF THE PROPOSED SITE PLAN The scope of work for the proposed development consists of an area of approximately 1.2 acres that includes the following: (1) culverting (approximately 220 LF) an existing intermittent stream, (2) replicating the associated wetlands (discussed by others under separate cover submitted with the Notice of Intent application), (3) construction of a new storage building (approximately 2,050 SF) shown on the Site Plan prepared by Parsons and Faia, (4) construction of an expanded crushed stone parking lot (approximately 12,400 SF) shown on the Site Plan prepared by Parsons and Faia, and (5) construction of a new paved go-cart track (approximately 24,000 SF) shown on the Site Plan prepared by Parsons and Faia,. The entire disturbed area shall be stabilized with lawn and landscaping. Some work (namely the proposed go-cart track and storage building) is to be located inside the 100-foot buffer zone and inside an isolated wetland resource area as identified by Bill Manual. Other work (namely the proposed parking lot expansion) is to be located partially within the inland bank wetland (intermittent stream) resource area and partially within the 100-foot buffer zone. The stormwater management system (proposed to mitigate for the runoff impacts from new impervious areas) is conservatively designed to fully comply with the Massachusetts Stormwater Policy. The proposed on-site closed drainage system is designed to collect and retain the runoff generated from the newly paved areas (new building and go-cart track) into an on-site proposed exfiltration system, and thereby minimize flowage off-site towards Robinson Road. The proposed on-site stormwater management system is designed to exfiltrate treated stormwater runoff through water quality structures including deep-sump catch basins and grassed swales. The proposed engineered combination of Best Management Practices (BMP's) for the stormwater design will provide: • Control of stormwater runoff quality and quantity, • Flood control minimizing the impact to the abutting Robinson Road by retaining (on-site)the first flush and retaining the 100-year 24-hour design storm (generated from the proposed pavement), • A decrease in the amount of pollutants that are discharged from the project site by providing (TSS) removal (based on Massachusetts Stormwater Policy and Guidelines), • A controlled watershed area in post-development conditions for the proposed parking lot (using crushed stone, on-site infiltration and additional landscaping), • Reducing the watershed area which discharges into Robinson Road, • An increase of treated water being infiltrated on the project site using a series of pre- �� 0http:)hnaps.live.caN*JnE9aXAuMfE0K3N3YWIwC[NvdHQrcm9h2CUyYytzYWx165UyYyttY5U3Z%NzdC4w7TdlcGcuM5LVl00M1900TQxOTA4NDMyMTkz]TdILTcwLjkxWMOMzYaT9T;; I IX� Google He Edit 'hew Favorites Tools Help Links F Uve Search Maps I I 1_°J Home ®Feeds(3) - F®7 Print - Pape - ( Tools " 114 swam scoff road,Salem, ma P eO rP Welcome I®Directions IICollections—IL;� Businesses People Collections Locations' � S � y, Af i Ai it "L y Y ,a s= J;y k;e y. t4 v e '�v .s 4 .c•,.l�ij., ^�. a"< �43 rL Fr ' f• a ' `�-'� •,.�+5{xFy i �� ���t-�' Rf 1p'w n�,�'^ ,��'.: � � J� `a yu � 'f�A �Mtj � .. � n^� � "aa�� l'+ •tui,. !, Y t � � � • , n Tom.. „ ':Y'13+yt,r,'d�`•i��+ ,ifA' � 6 Y 1�V `6 a% r� i �_ � �. ,•�• � �: -��. a ��* � � � � • � +. � ,; tom. � �~<�' d , 4-6-14 9' S4, •s a .�� ti c,ti e a.

All disturbed areas shall be properly stabilized with loam and permanent grass seed. Landscaping is proposed to further stabilize areas. Any fill will be clean sand fill (MHD M1.04.0) and loam (MHD M1.05.0). 4. HYDROLOGIC ANALYSIS & PURPOSE The purpose of the following hydrologic analysis is to determine the watershed characteristics and to determine stormwater runoff quantities based on accepted engineering methods. The analysis is used to compare the stormwater runoff flows of the existing conditions (pre- development) to those of the proposed "built-out" site (post-development conditions) stormwater runoff flows in order to conservatively design a drainage system and also to access down- gradient impacts to abutting properties (Robinson Road). b. PROPOSED DESIGN OBJECTIVES The design objective of the stormwater management system is to attenuate the difference between existing and proposed stormwater runoff flows (for the 2-year, 24-hour and the 10-year, 24-hour and the 100-year, 24-hour design storm events), so that there is no net increase of runoff to adjacent properties from the subject site. A second objective is to control, treat and manage water quality by removing TSS (total suspended solids) through structural and non-structural means (that require strict implementation of an Operation and Maintenance plan-attached in this report). These design objectives will mitigate for the impacts of the proposed project consistent with those standards set forth DEP's Stormwater Management Handbooks (Volumes One and Two, issued by DEP/CZM, March, 1997). c. DESIGN METHODOLOGY USED: SCS TR-55 AND SCS TR-20 The SCS TR-55 stormwater runoff modeling method was used to determine the watershed characteristics. SCS TR-20 stormwater routing method was used to model stormwater flow to calculate flows and runoff volumes. The computer program used is HydroCAD version 7.1 by Applied Microcomputer Systems, Inc., (a commonly used program by engineering companies with excellent technical support). Each watershed area is defined as a function of topography(ridgelinestwatershed divides) and the outlet points of discharge. Actual field survey data was used. On-site field reconnaissance was performed in order to confirm assumptions regarding watershed characteristics. The watershed areas are shown on the attached plans entitled: Watershed Analysis, Post(and Pre-) Development Conditions. Each watershed area has its own unique topography; cover type, runoff curve number and time of concentration as specified in the SCS TR-55 calculations. For the purposes of the watershed analysis, pre-development conditions are those conditions that exist today. The post-development conditions are those conditions that will exist when the site is"built out" as shown on the Site Plan. For this hydrologic analysis, PLDE assumed that the land uses off-site remained constant and was not changed between pre- and post development flows. Specifically, SCS TR-55 methods (using HydroCAD software)were used to determine Runoff Curve Numbers (CN)for each unique watershed area. The CN value is determined as a function of soil type and land use cover type. Land use cover type is based on site inspection and field survey. Soil types are based on SCS mapping (attached in Appendix#1) and actual soil testing performed by Parsons and Faia, Inc(see Site Plan). SCS TR-55 methods (using HydroCAD software)were used to determine Time of Concentration (TOC)which is the time that if takes for runoff to reach the outlet point of discharge measured based on land use cover type, slope of the land and drainage flow patterns (per SCS guidelines). SCS TR-20 stormwater modeling methods (using HydroCAD software)were used to determine runoff hydrographs for each watershed, then used to combine and route each hydrograph through stormwater controls at nodal points of discharge. Each control structure has an associated reservoir(leaching basin or some other form of runoff containment) called "pond" in the program. Stage-Storage-Discharge calculations for each reservoir are tabulated. Discharge calculations are based on the type of weir control structure and the amount of exfiltration (which is a function of the type of soil). The outlet points of discharge were selected to be the same point for each of the pre- and post-development scenarios, so that a comparison could be made at equal points. The following criteria was used for stormwater modeling purposes: a. Time increment for hydrograph coordinates: 1.0 hour= dt b. Rain table#7 corresponding to SCS Type III rainfall (recommended for Mass. by SCS) c. Antecedent Moisture Condition#2 (also recommended by SCS) d. Duration of storm: 24 hours (per Mass. Wetlands Protection Act regulations), Hydrograph time span = 0,00 to 30.0 hours e. Rainfall amount (P) for Framingham per a published report by the Northeast Regional Climate Center, Cornell University dated September, 1993: 100-year 24-hour storm: P = 7.4 inches 10-year 24-hour storm: P =4.25 inches 2-year 24-hour storm: P = 2.85 inches f. No tailwater condition g. Permeability rates: Hydrologic soil group "B" = 0.6 to 6.0 inches/hour (use 6"/hr based on the 3MPI perc rate) b d. DESCRIPTION OF HYDRAULIC PROFILES AND ASSOCIATED WATERSHEDS Existing hydraulic profiles and their associated watersheds are analyzed. In order to achieve the stormwater management design objectives, proposed hydraulic profiles are engineered with drainage controls in order to: (1) Maximize pre-treatment, thereby improving water quality through various treatment devices (structural and non-structural), by the removal of TSS (meeting the DEP's Standards for Stormwater Management for re-developed sites), (2) Segment (divide-up) the post-development watersheds into smaller(more- manageable) sub-watersheds (and then treat the stormwater in each sub-watershed using a variety of devices in-line(in an ordered sequence), (3) Take advantage of the Charlton series (as mapped by SCS) in-situ soils by installing a exfiltration device designed to infiltrate treated runoff on-site thereby minimizing stormwater from running off-site to Robinson Road and Swampscott Road, (4) Attenuate on-site (within the proposed hydraulic profile)the difference between pre- and post-development runoff flows. Each hydraulic profile is influenced by an associated watershed and its characteristics including (a) surface materials, (b) slopes (grading), and (c) design of drainage controls. The post- development hydraulic profile is an engineered sequence of structural BMP's (stormwater treatment devices: grassed swales and deep-sump catch basins) designed to achieve the objectives listed above for the proposed site development. PLDE performed a detailed hydrologic analysis (drainage calculations) using each of the following engineered hydraulic profiles (with the SCS stormwater routing modeling methodologies as described above). PRE-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#1-PRE): Runoff from the existing grassed and scrub area located south of the existing mini-golf course. The flow is overland (no catch basins exist) and is presently directed to Robinson Road (outfall point). The watershed area is approximately 30,000 SF (not considering runoff generated from the existing up-gradient mini-golf course). PRE-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#2-PRE): Runoff from the area adjacent to the existing depression located north of the existing mini-golf course (which includes the existing commercial building). Presently there is a 24-inch culvert receiving this flow (outpoint point at inlet). The existing culvert crosses Swampscott Road and discharges into a wetland on the eastside of Swampscott Road. This watershed area is approximately 12,600 SF (not considering runoff generated from the existing up-gradient mini-golf course, which also flows towards Swampscott Road culvert). PRE-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#3-PRE): Runoff from a portion of the existing crushed stone parking lot. The flow is overland (no catch basins exist) and is presently directed into the grassed swale along side Swampscott Road (outfall point), which then flows into the existing 24-inch culvert. This watershed area is approximately 12,000 SF. PRE-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#4-PREI: Runoff from the remainder of the existing crushed stone parking lot. Presently there is one catch basin (outfall point)within this watershed (located on the north end of the existing gravel parking area), which jhttp:((maps.live.comf#JnE9eXAUMTAwK3N3YWlwc2NYdHQrcmghZCLIyYytzYW)lb5UyYyttYSMZXNzdC4wJTdlcGcuMSZiY)02W~TgyODUzNzAn,z&y]TdLTMZLiEZNDc2NTYyf—m ;if-HE Google +Ile Edlt view Favorites Tools Help Links 1° 4 44 IJ Live Search Maps I I Home - ®Feeds(3) - (07 Print '- L4 Page - Tools - 100 swam scoff road,Salem, ma , T .... _ p ONfelcome J(DDirections I Collections Iu. � ECj ®usinesses Peaple.

The existing flow is overland, then into the existing catch basin. POST-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#1-POST): Runoff from the proposed go-cart track directed into a proposed on-site exfiltration system conservatively designed to retain the 10-year 24-hour storm event. The go-cart track is super-elevated sloping inward, therefore forming a detention basin shape (with the exfiltration system at the bottom). This watershed area is approximately 30,000 SF (not considering runoff generated from the existing up-gradient mini-golf course). The outfall point for this post-development watershed is Robinson Road (after the lag of the exfiltration system and detention area) after the go-cart track is flooded in an extreme storm event, there is over-flow onto Robinson Road (adjacent to the proposed wall (topples at top of wall = 61.0). For small storm events, the go-cart track is submerged for a very short time (less than 24-hours) and there is no over-flow onto Robinson Road. POST-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#2-POST): Runoff from the proposed crushed stone parking lot expansion project is directed towards and treated in a deep- sump catch basin and then discharged into a terminal-leaching basin (6-foot diameter, 6-feet tall concrete structure surrounded by 2-feet of crushed stone). The leaching basin in constructed in sand fill material (used for filling the existing depression). The deep-sump catch basin serves to remove approximately 25% of the total suspended solids (assuming the CB's are properly maintained). The crushed stone parking lot is to be graded with a gentle slope (4%). The on-site leaching basin exfiltration system is conservatively designed to retain the first flush and the entire 10-year 24-hour design storm. Any overflow from the proposed drainage system (which has been significantly lagged through the leaching basin exfiltration system) is directed towards the grass swale area between the new parking lot expansion and the Swampscott Road. This watershed area is approximately 12,600 SF (not considering runoff generated from the existing up-gradient mini-golf course, which also flows towards Swampscott Road culvert). The ouffall point is a new deep-sump catch basin connected to a leaching basin. POST-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#3-POST): Runoff from the proposed crushed stone parking lot expansion project is treated (via a water quality grassed swale that discharges into a deep-sump catch basin and then directed to the 24"culvert). This watershed area is approximately 12,000 SF. The outfall point is a deep-sump catch basin and connection to the 24-inch culvert. POST-DEVELOPMENT HYDRAULIC PROFILE (WATERSHED#4-POST): Runoff from the remainder of the existing crushed stone parking lot will remain substantially unchanged. The existing catch basin will be cleaned and maintained. Therefore, for the purposes of this hydrologic analysis, this watershed was treated similar to that of off-site existing conditions. e. CALCULATIONS: EXFILTRATION RATES The following are calculations to determine the exfiltration rates of each stormwater device designed to infiltrate (recharge)the pre-treated runoff water. The DEP (stormwater management standard#3) encourages recharge of the groundwater with pre-treated stormwater. The proposed stormwater management plan takes advantage of the-in-situ soils with moderate permeability rates(that allow for exhItration and groundwater recharge). Using properly designed exfiftration devices, excess runoff waters flowing off-site can be reduced (which typically would impact abutting properties). In this project design, the proposed stormwater management plan actually eliminates runoff generated from the new impervious surfaces (new go-cart track and new building)from flowing off-site through the use of the perforated drains surrounded by stone (leaching trenches). Exfiltration rate is a function of soil permeability and soil texture. The in-situ soils have been identified by on-site soil evaluation (testing using a backhoe) as follows: Hydrologic soil group "B" = 0.6 to 6.0 inches/hour (use 6"/hr based on a perc rate of 3 MPI performed in the field by Parsons and Faia, Inc.) RATE CALCULATION FOR THE LEACHING TRENCHES (GO-CART TRACK): Located inside Hydrologic Soil Group"B" SCS Permeability rate =6 inches/hour=0.00014 ft/sec 6 inches = 0.00014 ft/sec 12 in/ft x 3600 sec/hr Leaching bed bottom area =40'wide x 50' long = 2,000 SF Leaching bed sidewall area = (two sidewalls x 2' deep x 40') +2 sidewalls x 2' deep x 50') = 360 SF Total surface area of the crushed stone outer edge= 2,000 SF (bottom) + 360 SF (sidewalls) _ 2,360 SF Exfiltration Rate =0.00014 ft/sec x 2,360 SF = 0.33 CFS (cubic feet per sec) The invert for exfiftration is the bottom elevation of the trench, which is designed to be at least 2- feet above the estimated seasonal high groundwater(per test pits). Note: EAltration actually occurs within the adjacent in-situ soils on the sides and bottom of the trench, however, to be conservative, PLDE assumed no additional exfiltration rate for these adjacent in-situ soils (that lie adjacent to the leaching bed), since they are the soils actually receiving the flow from the leaching bed exflltration system. RATE CALCULATION FOR THE LEACHING BASIN (AREA OF PARKING LOT EXPANSION): Located inside Hydrologic Soil Group "B" SCS Permeability rate = 6 inches/hour= 0.00014 ft/sec 6 inches = 0.00014 ft/sec 12 in/ft x 3600 sec/hr The leaching basin system is composed of the concrete chamber(6-foot diameter chamber, 6- feet tall) +the surrounding crushed stone (2-feet around the basin on the sides, and 6-inches of stone on the bottom of the chamber, refer to detail sheet) The surface area of the leaching basin system (chamber and stone) bottom area = 3.14 (pie) x 5' x 5' (radius squared) = 78.5 SF The surface area of the leaching basin system sides (stone sides) = 2 x 3.14 (pie) x 5' (radius) x 6.5' (height of cylinder) = 204.10 SF Total surface area of outer edge of the crushed stone = 78.5 SF +204.10 SF = 282.60 SF Exfitration Rate= 0.00014 fttsec x 282.60 SF = 0.03956 CFS (cubic feet per sec) The invert for the crushed stone (exfiltration surface) is the same as the bottom of the crushed stone. Note: Exfltration actually occurs within the adjacent in-situ sandy/gravelly soils on the sides and bottom of the leaching basin, however, to be conservative, PLDE assumed no additional exfiltration rate for these adjacent in-situ soils (that lie next to the crushed stone), since they are the soils actually receiving the flow from the leaching basin exfiltration system). f. CALCULATIONS: STORAGE VOLUMES STORAGE VOLUME CALCULATION FOR THE LEACHING BED(GO-CART TRACK): The total available storage volume is calculated using the open-air volume of the pipe itself+the underground storage available in the underground storage available in the void spaces of the crushed stone (2"clean crushed stone, no stone smaller than 1.5" and no larger than 3"). Void spaces for crushed stone is 35% = void ratio. There shall be twelve 4" perforated pipes 4'O.C. each 50-feet long. Perforated Pipe open-air volume (4"diameter pipe) = 3.14 (pie)x 0.33' x 0.33' (radius squared) x 600 LF (length of pipe) =205 CF Leaching bed volume= 2000 SF x 2' deep =4,000 CF (cubic feet) Available storage volume =4,000 CF x 0.35 (void ratio) = 1,400 CF Total available storage volume for the leaching bed system (pipe and stone) = 205 CF (pipe) + 1,400 CF (stone) = 1,605 CF Note:Additional storage volume actually occurs within the adjacent soils on the sides and bottom of the leaching bed, however, to be conservative, PLDE assumed no additional storage volume for these adjacent in-situ soils (that lie next to the crushed stone), since they are the soils actually receiving the flow from the leaching bed exfitration system. STORAGE VOLUME CALCULATION FOR THE LEACHING BASIN (AREA OF PARKING LOT EXPANSION): The total available storage volume is the sum of the volume (air-space) in the basin chamber(concrete structure) and the calculated underground storage available in the void spaces of the crushed stone (2" clean crushed stone, no stone smaller than 1.5"and no larger than 3"). Void spaces for crushed stone is 35% =void ratio. Storage volume available in the concrete leaching basin structure: 6' tall basin x 3.14 (pie) x 3' x 3' (radius squared) = 169.5 CF The invert for the concrete structure is the same as the bottom of that structure. Storage volume available in the crushed stone: Volume of leaching basin with crushed stone =6' tall basin x 3.14 (pie) x 5' x 5' (overall radius squared) =471 CF Volume of stone (on sides) =471 CF (overall)— 169.5 CF (concrete structure) = 301.5 CF The invert of the crushed stone on the side is the same as the bottom of the concrete structure. Volume of stone below basin = 0.5' high x 3.14 (pie) x 5' x 5' (radius squared) = 39.25 CF The invert for the crushed stone on the bottom of the concrete structure is the same as the bottom of the stone. Total volume of stone = 301.5 CF (sides) + 39.25 CF (below basin) =340.75 CF Available storage volume for stone= 340.75 CF x 0.35 (void ratio) = 119.26 CF Note: Additional storage volume actually occurs within the adjacent soils on the sides and bottom of the leaching basin, however, to be conservative, PLDE assumed no additional storage volume for these adjacent in-situ soils (that lie next to the crushed stone), since they are the soils actually receiving the flow from the leaching bed exfiltration system. g. CALCULATIONS: TSS REMOVAL TSS is removed with each incremental (sequential) pre-treatment device. Calculations for TSS removal are based on the methodology established in DEP's Stormwater Management Standards. By removing total suspended solids (TSS)from the stormwater(and those oils/greases that adhere to those sediment solids), the runoff water quality can be greatly improved of the treated discharge. The TSS removal rates are per a table in DEP's Stormwater Management Standards, Volume 1, page 1-7(attached herein). Calculations for TSS removal for the proposed hydraulic profiles are as follows: PROPOSED HYDRAULIC PROFILE (WATERSHED#1-POST): BMP#1: Pavement Sweeping (go-cart track)= 10% BMP#2: Water quality grassed swale = 70% BMP#3: Deep-Sump Catch Basin = 25% BMP#4: Exfiltration system (leaching bed) = 80% TSS Removal Calculation: BMP#1: 10% (removal rate) x 1.0 (initial TSS) = 10% (TSS removed by BMP#1) Amount of TSS remaining after BMP#1 = 100% - 10% = 90% Convert: 90% divided by 100 = 0.90 BMP#2: 70% (removal rate) x 0.9 (remaining TSS) =63% (TSS removed by BMP#2) Amount of TSS remaining after BMP#2 = 90% -63% = 27% Convert: 27% divided by 100 =0.27 f BMP#3: 25% (removal rate) x 0.27 (remaining TSS) =6.75% (TSS removed by BMP#3) Amount of TSS remaining after BMP#3 = 27% -6.75% =20.25% Convert: 20.25% divided by 100 = 0.2025 BMP#4: 80% (removal rate) x 0.2025 (remaining TSS) = 16.20% (TSS removed by BMP#3) Amount of TSS remaining after BMP#4 =20.25% - 16.20% =4.05% Total TSS removed by BMP#1, BMP#2, BMP#3 and BMP#4 = 100% (initial TSS)—4.05% (TSS remaining after BMP#4) = 95.95% > 80% (COMPLIES) Therefore, the stormwater water quality devices proposed in sequence will exceed DEP's Stormwater Management Standard#4 of 80% TSS removal. PROPOSED HYDRAULIC PROFILE (WATERSHED#2-POST): BMP#1: Crushed stone parking lot(retains sediment in between void spaces) = 10% BMP#2: Deep-Sump Catch Basin =25% BMP#3: Exfiltration system (leaching basin) = 80% TSS Removal Calculation: BMP#1: 10% (removal rate) x 1.0 (initial TSS) = 10% (TSS removed by BMP#1) Amount of TSS remaining after BMP#1 = 100% - 10% = 90% Convert: 90% divided by 100= 0.90 BMP#2: 25% (removal rate)x 0.9 (remaining TSS) =22.5% (TSS removed by BMP#2) Amount of TSS remaining after BMP#2 = 90% -22.5% = 67.5% Convert: 67.5%divided by 100 =0.675 BMP#3: 80% (removal rate) x 0.675 (remaining TSS) = 54% (TSS removed by BMP#3) Amount of TSS remaining after BMP#3 =67.5% - 54% = 13.5% Total TSS removed by BMP#1, BMP#2, and BMP#3 = 100% (initial TSS) - 13.5% (TSS remaining after BMP#3) = 86.5% > 80% (COMPLIES) Therefore, the stormwater water quality devices proposed in sequence will exceed DEP's Stormwater Management Standard#4 of 80% TSS removal. PROPOSED HYDRAULIC PROFILE (WATERSHED#3-POST): BMP#1: Crushed stone parking lot(retains sediment in between void spaces) = 10% BMP#2: Water quality grassed swale =70% BMP#3: Stone filter check dams =25% BMP#4: Deep-Sump Catch Basin =25% TSS Removal Calculation: BMP#1: 10% (removal rate) x 1.0 (initial TSS) = 10% (TSS removed by BMP#1) Amount of TSS remaining after BMP#1 = 100% - 10% =90% Convert: 90% divided by 100 = 0.90 BMP#2: 70% (removal rate) x 0.9 (remaining TSS) =63% (TSS removed by BMP#2) Amount of TSS remaining after BMP#2 = 90% -63% =27% Convert: 27% divided by 100 =`0.27 BMP#3: 25% (removal rate) x 0.27 (remaining TSS) = 6.75% (TSS removed by BMP#3) Amount of TSS remaining after BMP#3 = 27% -6.75% = 20.25% Convert: 20.25% divided by 100 = 0.2025 BMP#4: 25% (removal rate) x 0.2025 (remaining TSS) = 5.06% (TSS removed by BMP#3) Amount of TSS remaining after BMP#3= 20.25% -5.06% = 15.19% Total TSS removed by BMP#1, BMP#2, BMP#3 and BMP#4 = 100% (initial TSS)— 15.19% 0 (TSS remaining after BMP#4) = 84.81 0� > 80% (COMPLIES) Therefore, the stormwater water quality devices proposed in sequence meets DEP's Stormwater Management Standard #4 of 80% TSS removal. 5. COMPARATIVE ANALYSIS at WATERSHED OUTFALL POINT of DISCHARGE The proposed development will alter the drainage watersheds that exist on-site today. In order to compare pre-development runoff rates to post-development runoff rates, an outfall point of discharge was determined for each watershed. The outfall point of discharge (shown on the attached watershed photograph) is the same for both pre- and post development conditions in order to compare the pre-and post-development flows (CFS) cubic-feet per second. The following are the results of the computer-run model using the methodologies as described above. The following is a table showing the comparison of runoff rates for the existing (pre- development)watersheds verses the runoff rates that will result with the proposed stormwater management plan at the specific outfall point. COMPARISON BETWEEN PRE-and POST-DEVELOPMENT FLOW RATES (CFS). FOR THE OUTFALL POINT OF DISCHARGE FOR THE 2-YEAR, 24-HOUR MAXIMUM DESIGN STORM OUTFALL POINT PRE-DEVELOPMENT POST-DEVELOPMENT #1 0.12 CFS 0.00 CFS #2 0.13 CFS 0.00 CFS TOTAL FLOW OFF-SITE 0.25 CFS 0.00 CFS COMPARISON BETWEEN PRE-and POST-DEVELOPMENT FLOW RATES (CFS).

In the built-out scenario(post development), the pre- treated runoff generated from the watersheds has been captured in the proposed stormwater management system and is retained on-site recharging the groundwater and eliminating stormwaters from flowing off-site. I 6. OPERATION & MAINTENANCE PLAN FOR THE PROPOSED WATER QUALITY CONTROLS (BMP's) Stormwater quality at the project site will be controlled with the implementation of the BMP's described below. Proper maintenance is required in order to insure that each structural and non- structural method of pre-treatment is functioning as designed and will continue to be effective in the removal of total suspended solids from the runoff water. The project proposed utilizes a closed drainage system designed to maximize long-term protection of surface and groundwater resources by reducing the contribution of sediments and adsorbed contaminants to the storm drainage system. The proposed site maintenance measures include: (1) routine trash, debris and litter removal, (2) regular sweeping of all paved surfaces, (3) routine cleaning of catch basin sumps, and infiltration basins by removal of any silt that may accumulate, (4) regular mowing and grass clippings/leaf removal. The proposed stormwater management design relies heavily upon the following Operation & Maintenance Plan. This plan requires the identification of a person who will be responsible for the operation and maintenance of the stormwater management systems. Maintenance schedules are specified. This Operation and Maintenance plan is prepared in accordance with DEP/CZM Performance Standard#9.

NON-STRUCTURAL METHODS 1. Site Layout Planted buffers along the perimeter of the site are proposed (designed by others) where possible. The site design focused on providing graded areas for the runoff to be directed to, so that runoff could be retained on-site, thus recharging the groundwater and reducing the overland runoff flow to adjacent properties. Following construction a comprehensive landscaping program is required in order to cover the ground with landscape materials, thus eliminating exposed soils. Stabilize Newly Graded (and/or disturbed)Areas: Use an erosion control seed mixture. Hay mulch shall be applied to these newly graded and/or disturbed areas. Hay mulch is applied by breaking apart a haybale and spreading a light mesh layer on the exposed newly graded and/or disturbed earth. 2. Source Control During and after construction, a comprehensive source control program is required to be implemented at the site, to include (1) regular(quarterly) pavement sweeping, (2)trash detail (picking up and proper disposal of trash and debris that may accumulate), and (3) catch basin cleaning (quarterly), (4)exfiltrabon system cleaning (semi-annually). Regular pavement sweeping will reduce sediment loading from paved areas to the catch basins. Regular pavement sweeping is an effective source reduction management measure to reduce the overall loading of total suspended solids before they can be washed off paved areas into the sumps of the catch basins. An effective sweeping program reduces contaminant loading by collecting and removing particulate matter and the adsorbed contaminants at the source, before these contaminants become components of the stormwater. Site inspections during construction shall be performed once per week. Remove any trash as required. Debris shall be hauled away from the site and properly disposed of in accordance with municipal requirements. Protect Earth Piles: The number and height of earth piles shall be minimized. Piles of earth shall be covered with haymulch and seeded. A row of haybales shall be staked in place on the down-gradient side of the earth pile to prevent erosion of the earth pile from rainwater and/or wind erosion. b. STRUCTURAL METHODS Several structural BMP's (pre-treatment devices) are proposed for the project site to maintain water quality and reduce the amount of total suspended solids (TSS) in the runoff. The DEP/CZM Stormwater Management Policy requires stormwater management systems to remove a minimum of 80% of the average annual load of TSS. The proposed stormwater management system is composed of multiple BMP's and will remove more than 80% TSS (refer to the above TSS removal calculations). Each structural method is discussed below. 1. Catch Basins The proposed catch basins at the site are to be constructed with deep four(4)foot sumps. Catch basins shall be cleaned at least four (4) times per year. A series of catch basins and sediment sumps will be installed to (a)facilitate in the collection of runoff from the proposed paved surfaces, (b) reduce the transport of sediment, thus removing TSS, and (c) pre-treat the discharging runoff. The operating capacity of the sumps shall be maintained by cleaning them quarterly; focusing on the late fall prior to winter sanding season (to thoroughly remove leaves), and another focused cleaning early spring, after the majority of the snow has melted to remove accumulated sediments and floatable contaminants. A site maintenance contractor will clean each catch basin sump with a clamshell device (mounted on the back of a dump truck) or a vacuum pump-truck. The silt and sediments accumulated in the sumps will be removed and properly disposed of off-site in accordance with municipal regulations. During construction, each catch basin shall be protected from silt and debris by the installation of silt fabric (under each CB grate). During construction, haybales shall be staked in place around each catch basin. 2. Subsurface Exfiltration Systems Two exfiltration systems (leaching trenches and leaching basin) are proposed for the go- cart area and the parking lot(respectively). They are designed to receive runoff and allow percolation through the crushed stone and mirafi fabric that surrounds the system, thus exfiltrating treated stormwater into adjacent gravelly in-situ soils. Semi-Annual cleaning (by removal of silt and debris) is required. i • Atlas of Precipitation (prepared by Cornell University) Rainfall amounts for design storms • SCS soil map and soil descriptions, tables I Appendix #1 Tables and Figures for Reference OR�'HEAST REfiIONAL LfMAfif CENTER- -, Alas of pr6cipita#ion Extremes for the Northeastern United States "and .

Stormwater runoff to be treated for water quality is based on the following calculations: �I�U a. ❑ 1 inch of runoff x total impervious area of post-development site for discharge to critical areas (Outstanding Resource Waters, recharge areas of public water supplies, shellfish growing areas, swimming beaches, cold water fisheries). Note: b. ® 0.5 inches of runoff x total impervious area of post-development site for other resource areas. This November 2000 version of the Stormwater Management B. Stormwater Management Standards Form supersedes earlier versions including those DEP's Stormwater Management Policy(March 1997) includes nine standards that are listed on the contained in following pages. Check the appropriate boxes for each standard and provide documentation and DEP's additional information when applicable. Stormwater Handbooks. Standard#1: Untreated stormwater a. ® The project is designed so that new stormwater point discharges do not discharge untreated stormwater into, or cause erosion to, wetlands and waters. Standard#2: Post-development peak discharges rates a. ❑ Not applicable—project site contains waters subject to tidal action. Post-development peak discharge does not exceed pre-development rates on the site at the point of discharge or downgradient property boundary for the 2-yr, 10-yr, and 100-yr, 24-hr storm. b. ❑ Without stormwater controls c. ® With stormwater controls designed for the 2-yr, and 10-yr storm, 24-hr storm. d. ® The project as designed will not increase off-site flooding impacts from the 100-yr, 24-hr storm.
