The ptupose of this report is to document compliance with the Massachusetts Department of Environmental Protection's Stormwater Policy in support of a Notice of Intent being filed with fhe Salem Conservation Commission. l.l CurrenY Conditions The overall project site consists of the parcels located at 265 Canal Street(Mackey), 285 Canal Street(Weir) and a portion of the parcel located at 70 Loring Avenue (Stanley). There is a City-owned bicycle path constructed along on the former Boston and Maine Railroad right-of-way which runs through the overall property separating the Weir parcel to the southwest from the Mackey and Stanley parcels to the nor[heast. The Mackey and Stanley parcels are contiguous except there is a paper street right-of-way, designated as Clover Street,which runs southwest from Broadway,northeast of the site,to the bike path right-of-way. Pre-redevelopment conditions and drainage subcatchments are shown on the enclosed Sheet DR-], Pre-Redevelopment Watershed Plan. 1.1.1 Weir Site � The Weir site is an approximately 1.5-acre parcel curcently occupied by a two-story industrial building. The building footprint is approximately 35,300 square feet(s� covering ' approximately 54% of the lot area. Designated paved parking areas on the Weir site consist of a 17-space lot located ❑orthwest of the building, an 8-space lot located adjacent to the Canal Street entrance along the southwest face of the building, and an 8-space lot adjacent to Loring Avenue along the southeast face of the building yieldmg a total of 33 parking spaces. Other areas in the southwestern portion of the site are occupied by gravel surfaces and used informally for parking although no marked spaces are provided. Stormwater from the northern portion of the Weir site (Subcatchment 11) flows northerly as surface runoff to catch basins connected to the 36-inch storm drain located beneath the bike path. This runoff includes roof drain discharges to the ground surface from a series of downspouts on the existing building. Site coverage is primarily impervious surfaces including portions of the existing building and paved parking. Ground slopes are moderately flat. Stormwater from the southeastern portion of the site(Subcatchment 12) flows to on-site catch basins. Record plans indicate that these structures discharge to the sanitary sewer system in Loring Avenue. Site coverage is primarily impervious surfaces including portions of the existing building and paved parking. Ground slopes are moderately flat. Stormwater from the southwestern portion of the site (Subcatchment 13) flows to on-site catch basins locafed in the paved and gravel parking areas. Record plans provided by the City of Salem indicate that these struc[ures discharge to a sanitary sewer main which runs across the site connecting the sanitary sewer in Canal Street to the sanitary sewer in Loring Avenue. Site coverage is primarily impervious surfaces including portions of the existing building and paved parking. Ground slopes are moderately flat. OCG Project 13037 Page 1 November 21,2013 , 11.2 Mackey/Stanley Site ' The Mackey site located at 265 Canal Street is an approximately 0.7-acre parcel occupied ' by a two-story building formerly known as The Salem Tron Foundry. This site is developed contiguously with the northwestern portion of the Stanley site forming a paved parking lot with access from Canal Street. The poRion of the Mackey site located northeast of the building is a grass area with frontage on Broadway. Collectively,the Mackey and Stanley sites along with a developed portion of the Clover Street right-of-way provide a total of 52 designated paved parking spaces. Site observations indicate That additional parking capacity is provided by informa] parking on striped pavement in the northeast portion of the Stanley site near the wooded area. Stormwater from the southwestern portion of the site(SubcaYchmenY 21) flows southwesterly to catch basins connected to the 36-inch storm drain in the bike path. Site coverage is primarily impervious surfaces including portions of the existing building and paved parking. Ground slopes are moderately flat. Stormwater from the northeastem portion of the Mackey/Stanley site flows south as surface runoff to a low-lying wooded area beyond the paved parking on the northeast side of the Stanley lot. This area also receives runoff from the Clover Street right-of-way,Broadway and abutting properties to the northeast. Site coverage is mostly impervious surfaces including portions of the existing building and paved parking with some wooded vegetated area. Ground slopes are moderately flat. Site topography indicates that the wooded area serves as a natural detention/retention basin. However, stormwater calculations indicate that the storage capacity of the wooded area is exceeded during significant rainfall events resulting in overflow onto thc existing parking lot and ultimately combining with the runoff from the southwestem portion of the sife flowing to the bike path drainage system. 1.2 Site Geology and Hydrogeology Site soil information was obtained from a Phase II Comprehensive Site Investigation report for 285 Canal Street perforcned by Rizzo Associates, Inc. (Rizzo) dated December 3, 1992. According to soil borings performed by Rizzo during that investigation, subsurface materials at the site consist of poorly- drained sandy silt and gravel fill materials over marine silts and clay. Bedrock was not encountered. According to Rizzo's soil borings, ground water depths at the site are generally shallow and estimated to be approximately three feet below�ound surface in the area of the parking lot northwest of the Stanley Building. According to the U.S. Department of Agricul[ure Natural Resources Conservation Service (NRCS) Soil Map for Essex County, site soils are classified as Urban Land. No NRCS hydrologic soil group is provided for Urban Land. Based on the soil information provided in Rizzo's Phase II report , compared to soils types shown on the RawPs Table, site soils are interpreted to be hydrologic soil group C. l3 Proposed lmprovements The Project consists of razing the existing Weir and Mackey Buildings and constructing temporary paved parking lots. A site plan showing the proposed pazking lot construction is shown on OCG Project 13037 Page 2 November 21, 2013 f Sheet C-2.0. The specific elements of the Project for the Weir and Mackey/Stanley sites are described below. Post-redevelopment conditions and drainage subcatchments are shown on the enclosed Sheet DR- 2,Post-Redevelopment Watershed Plan. 1.3.1 Weir Site The demolition plan for the Weir Building is to terminate existing utility services, raze the existing structure,remove the floor slab, and cut off footings/frost walls approximately two feet below proposed finish ground surface. The proposed parking lot layout will provide a total of 156 parking spaces, of which six will be accessible in accordance with Americans with Disabilities Act(ADA) requirements. A bus stop shelter will also be provided. Site work will be limited to the Weir site itself and existing paved parking in the northeastern portion of the site that extends onto the bike path right-of-way will remain in place. At the request of the City of Salem,two existing catcb basins locaYed in the southwestern portion of the site near Canal Street will be closed and abandoned. The third catch basin in this area of the site, which is constructed over the sewer main connecting systems in Canal Street to Loring Avenue,will be converted to a sewer manhole. The site will be regraded to direct runoff either to the storm drain system in the bike pafh to the north or to the remaining on-site catch basins in the southeastern portion of the site near Loring Avenue. In addition, the project may include sewer separation work consisting of a new storm drain pipe from this catch basin system to an existing drain manhole in Loring Avenue. This work is identified as Alternate work on Sheet C-2.0. Changes in ground surfaces for work on the Weir site are summarized in the table below. Sudace Exisring (s� Proposed(s� Change(s� Buildings 35,356 — (35,356) Pavement 24,163 62,689 38,526 Gravel 7,739 -- (7,739) Grass 4,986 9,555 4,569 Constructing the temporary parking lot on the Weir site will result in a decrease in impervious surfaces(buildings, rooftops and compacted gravel) of approximately 4,569 sf. Based on the temporary nature of the project, the grading and drainage strategy will be to maintain existing conditions to the greatest extent practicable. Stormwater from the northern portion of the site (Subcatchment 11) will continue to flow to the north as sheet runoff to the storm drain system in the bike path. The ground coverage will be primarily impervious pavement with flat slopes. Stormwater from the southem portion of the site (Subcatchment 12)will continue to flow into existing catch basins located in the southeastem portion of the site. These catch basins currently connect to the sanitary sewer in Loring Avenue. The inlet grate elevations of these structures will be reset to match proposed grades of the site and cleaning or other measures will be required to restore functionaliry. The project may also indude connecting these structures to an existing drain manhole in Loring Avenue. The ground coverage will be primarily impervious pavemenY with flat slopes. OCG Project 13037 Page 3 November 21, 2013 132 Mackey/Stanley Site The demolition plan for the Mackey building will be similar to the plan for the Weir building and consist of terminating utili[y services, removing floor slabs and cutting footings/frost walls approximately two feet below the proposed ground surface. Portions of the paved parking and driveways north of the Canal Street curb cut will be removed but the majority of the Stanley i building parking lot will remain. As shown on Sheet G2.0, the existing Stanley parking area will be expanded onto the portions of the Mackey site currently occupied by the building and grass area. The existing parking area will also be widened to provide an additional row of parking along the wooded area to the northeast. The overall parking lot layout will provide a total of 128 spaces for a net increase of 76 new spaces. A total of five handicap spaces are required for parking lots of this size. Stormwater from the southwestem portion of the site (Subcatchment 21)will continue to flow to catch basins connected to the 36-inch storm drain in the bike path. Site coverage will continue to be primarily impervious surfaces with rooftop areas and areas of compacted gravel being replaced with paved parking but no increase in impervious area is proposed. Ground slopes are moderately flat. Changes in ground surfaces for the southwestern portion of the Mackey/Stanley site are summarized in the table below.

Portions of the wooded area will be regraded to provide enhanced treatment and detention of this additional runof£ Changes in ground surfaces for the northeastern portions of the Mackey/Stanley site, including offsite areas, are summarized in the tables below: OCG Project 13037 Page 4 November 2l, 2013 Mackey/Stanley Northeast—To Wooded Area(Subcatchment 22) Surface Existing (s� Proposed(s� Change(s� Btildings 6,512 4,�56 (1,756) Pavement 29,281 38,937 9,656 Gravel 4,345 976 (3,369) Grass/7'rees 31,609 28,529 (3,080) ' Tota1 71,747 73,198 1,451 Due to the temporary nature of the project,the grading and drainage strategy will be to maintain existing conditions to the greatest exYent practicable. No new impervious areas will be created in the southwestemern portion of the Mackey/Stanley site so no new stormwater Best Management Practices(BMPs)are proposed. Changes in site runoff from this area are attributable to minor changes in the contributing watershed area due to razing the Mackey building and the resulting site grading. BMPs to accommodate groundwater recharge and water quality requirements associated with the increase in impervious area in the northern portion of the Mackey/Stanley site consist of an infiltration trench with a vegetated filter strip for pretreahnent. OCG Project 13037 Page 5 November 21, 2013 2.0 STORMWATER MANAGEMENT STANDARDS CONFORMANCE The measures taken to address each of the performance standards of the Massachusetts Department of Environmental Protection Stormwater Policy are presented below. 2.1 Untreated Stormwater(Standard 1) The proposed project will not result in new discharges or outfalls. Existing stormwater runoff patterns will be maintained. 2.2 Post-Expansion Peak Discharge Rates (Standard 2) Pre- and Post-redevelopment runoff rates were calculated using HydroCAD. As shown in the table below,peak discharge rates from the overall project will not inerease in the Post-redevelopment condition. The increase in impervious area contributing runoff to the wooded area will be mitigated by constructing an infiltration trench and increasing storage capacity with the surrounding grading. The HydroCAD calculations can be found in Appendix C. Storm Event E�cisting Proposed Change (cis) (cfs) (cfs/%) 2-Year 7.51 633 -1.18(-16%) (31 Inches) 10-Year I 1.09 9.49 -1.60(-14%) (4.5 Inches) 25-Year 16.55 13.48 -3.07 (-19%) (5.4 Inches) 100-Yeaz 21.84 2023 -1.61 (-7%) (6.7 Inches) 2.3 Recharge to Groundwater(Standard 3) An infiltration trench will be constructed in the wooded area in the northeast portion of the Stanley site. The required rechazge volume is based on the new impervious area(4,531 s� in the northeastem portion of the Mackey/Stanley site using a recharge rate of 0.25 inches for Type C soils. Recharge volume calculations are provided below. (4,531 ft�)x (0.25 in)x (�/iz ft/in)=94 cubic feet(c� Infiltration to groundwater was modeled sTaYically by calculating the storage provided in the infiltration trench as summarized below. Stone filled trench (40%voids): 0.40 x (125 ft x 8 ft x OSft)=200 cf OCG Project 13037 Page 6 November 21, 2013 2.4 Water Quality(Standard 4) The Massachusetts Stormwater Handbook requires 80 percent Total Suspended Solids (TSS) removal. This objective is met for the northern poRion of the Mackey/Stanley site by the proposed infiltration trench BMP with pretreatmen[by a vegetated filter strip and pea stone diaphragm. The water quality volume for the trench is based on the new impervious area for the contributing subcatchment as follows: (4,531 f[�)x (0.50 in) x ('/�z ft/in)= 189 cubic feet(c� The water quality volume provided by the infilh-ation trench is 200 cf in accordance with the volume calculations provided for Standard 3. 2S Lar�d Uses with Higher Potential Pollutant Loads (Standard 5) SSU is a College/University. This use does not meet the definition of a Land Use with Higher Potential Pollutant Loads (Li7IiPPL) as defined by the MA DEP. 2.6 Protection of Critical Areas (Standard 6) The site does not contain critical environmental resource areas. 2.7 RedevelopmentProjecY(Standard 7) The project is a mix of redevelopment and new development. The Weir site and southwestern portion of the Mackey/Stanley site are considered a redevelopment since no increase in impervious area is proposed. The Stormwater Management Standards for this portion of the project have been met to the greatest extent practicable. Standards ], 8, 9 and ]0 have been met in full. The northeastem portion of the Mackey/Stanley site is considered�ew development since an increase in impervious area is proposed. All standards have been met in full for this portion of tUe project. 2.8 Construction Period Erosion/Sediment Control (Standard 8) Erosion and sediment control barriers are proposed along both side of the bike path as shown on Sheet C-2.0. In addition,iolet protection will be provided for catch basins receiving runoff from the project site. These measures will be installed prior to the start of work and maintained by the Contractor for the duration of project construction. Additional Erosion control notes and required measures are provided on Sheet G4.0. The project will disturb more than one acre and require a Stormwater Pollution Prevention Plan (SWPPP)under the National Pollution Discharge Elimination System (NPDES) Construction General Permit(CGP). The SWPPP will be prepared prior to filing the NOI for coverage under the CGP and the start of construction. 2.9 Oparation and Maintenance Plan(Standard 9) SSU maintains an Operation and Maintenance (O&M)Plan for campus parking lots. A copy of the plan is enclosed as Appendix B. OCG Project 13037 Page 7 November 21, 2013 � 210 Prohibition of Illicit Discharges(Standard 10) , The project consists of a temporary paved parking lot and does not include any illicit discharges.

The procedures presented below have been developed to be practical to implement and sufficiently protective of nearby resource areas and the environment in general. 2.1 Vehicle Parking The Canal Street Parking lot consists of two separate paved parking lots located at 265 and 285 Canal Street in Salem,Massachusetts. These lots provide a tota1284 parking spaces. The lots are used exclusively for vehic1e parking by Salem State University students, faculty and sYaf£ The Canal Street pazking lot is also accessed by a campus shuttle bus to transport passengers from the lot to other areas of the Salem State University campus. 2.2 Housekeeping Cleanup to remove accumulated trash and debris shall be performed on both an as-needed and scheduled basis. Routine cleanup activities include the following: 2.2.1 Trash and Debris Pickup Trash and debris pickup shall be performed continuously as part of campus-wide trash and debris pickup program. Personnel shall be respo�sible for removing litter as well as other natural debris, such as fallen branches. Students, faculty and staff are prohibited from lirtering and are encouraged to pickup miscellaneous debris which they may encounter. 22.2 Sweeping Street sweeping of parking areas shall be performed twice a year during the spring and fall. Recovered sweepings shall be disposed in accordance with the Salem Conservation Commission requirements. OCG Project 13037 Page 1 November 21, 2013 23 Snow Plowing/Deicing Snow and ice removal operations shall be performed on an as-needed basis. Snow from parking areas and wallcways shall be plowed to the sides of the paved surfaces in accordance with customary snow plowing procedures. Snow shall be plowed away from wetlands resource areas. Snow stockpiles shall be located beyond wetlands buffer zones to the greatest extent practicable. Snow banks or piles may be removed from parking lots or other critical areas as needed. Deici�g operations consist of applying sand or salt to walkways and other paved swfaces as needed for staff and pedestrian safety. 3.0 OPERATION AND MAINTENANCE Faeility personnel shall inspect the stormwater management systems on a routioe basis. Inspection and maintenance shall be performed as follows: 3.1 Catch Basins and Manholes Catch basins and manholes shall be inspected for accumulation of silt, sediment, or debris on a semi-annual basis. Cleaning will be performed at least once per year or more frequently if the sediment level rises 2 feet above the bottom of the sump. Removed sediment will be disposed off site by a qualified waste disposal contractor in accordance with state and federal regulations. 3.2 Infiltration Systems � Infiltration systems consisting of infiltration trenches shall be inspected for accumulation of silt, sediment, or debris on an annual basis. Cleaning will be performed at least once every two years or more frequently if sediment or debris is observed in the system. Removed sediment will be disposed off site by a qualified waste disposal contractor in accordance with state and federal regulations. 3.3 Record Keeping The Owner shall complete the Stormwater System inspection Report(Appendix A) as part of routine inspections. Copies of completed reports shall be kept for a period of at least 5 years.

("Epsilon") is pleased to submit this Notice of Intent ("NOI") to the Salem Conservation Commission (the "Commission"). The NOI has been � prepared in accordance with the Massachusetts Wetland Protection Act (MGL c.131 s.40) and implementing Regulations (310 CMR 10.00) (the "Act"). Because the Applicant is an agency of the Commonwealth of Massachusetts the Salem Wetlands Protection Ordinance � does not apply. The activities described in the enclosed NOI include the demolition and removal of existing , buildings and the construction of a parking lot on 3 parcels of land located at 265 & 285 Canal Street and 70 Loring Avenue in Salem; MA (the "ProjecY'). Other proposed work includes modifications to the existing stormwater management system, site lighting, ' emergency phones and a shuttle bus stop shelter. The majority of the work will occur within land subject to coastal storm flowage ("LSCSF") (elevation 11.3 feet NGVD29) and , therefore requires review and approval from the Commission under the Act. Please refer to the sections below for a more detailed discussion of the project and activities proposed in LSCSF. ' 2.0 Description of Existing Site Conditions & Wetland Resource Areas ' The Project site consists of 3 parcels of land owned by Salem State Universiry Assistance Corporation located at 265 & 285 Canal Street and 70 Loring Ave (see Attachment B, Figures t and 2). The surrounding area .consists of dense residential and commercial � development and Salem State University's ("SSU") Central Campus situated to the south. 265 Canal Street, referred to as the "Mackey Property", is an approximately 0.7-acre parcel located at the north extent of the Project area occupied by a high-bay one story building � ' formerly known as The Salem Iron Foundry. East of the existing building is a grassed area with frontage on Broadway. 70 Loring Avenue, referred to as the "Stanley Property" is an il , adjacent approximately 1.32-acre parcel that contains an existing two story building (to be retained) and associated parking and landscaping. The Mackey and Stanley parcels are contiguous except there is a paper street right-of-way, designated as Clover Street, which 'I ' runs west from Broadway, which is east of the Project site, to a municipal bike path right-of- way outside of the Project area. Collectively, the Mackey and Stanley sites, along with a developed portion of the Clover Street right-of-way, contain a total of 52 designated paved � parking spaces. 285 Canal Street, referred to as the "Weir Properry", is an approximately 1.5-acre parcel located at the south extent of the Project area and is currently occupied by an industrial building and associated paved parking, walkways, landscaping, and other , miscellaneous site improvements. The aforementioned municipal bicycle path, constructed on the former Boston and Maine Railroad right-of-way, roughly bisects the Project area and , separates the Weir parcel to the southwest from the Mackey and Stanley parcels to the NOl/SalemStateUniveisityCanalStreetParkingLot 1 AKachmentA-Narrative Epsilon Associates, Inc. ' ' northeast. The parcel containing the bike bath, located at 267 Canal Street, is owned by the ' City of Salem. No work is proposed on the City-owned bike path parcel. LSCSF is defined at 310 CMR 10.04. MassDEP uses the 100 year coastal flooding event, as t defined and mapped by the Federal Emergency Management Agency ("FEMA") per the National Flood Insurance Rate Program, as the maximum flood elevation associated with ' LSCSF, unless recorded storm data reveal a higher flood elevation (which is the "storm of record"). The "preliminary" 2013 FEMA Flood Insurance Rate Map ("FIRM") depicts the ' Forest River Estuary, including portions of the Project site and the Salem State University central campus, as being within FEMA's Coastal Flood Zone AE. This is a special flood hazard area subject to inundation by the 1% annual chance (or 100 year) flood. The Base � Flood Elevation ("BFE") shown on the map for this particular AE Zone is 11 feet relative to the North American Vertical Datum of 1988 (NAVD88), which is equivalent to 11.8 feet (NGVD29). See Attachment B, Figure 3, Preliminary FEMA Flood Hazard Data. However, ' as noted on the FIRM, the BFEs shown on the FIRM represent rounded whole-foot elevations. For more detailed information in areas where BFEs have been determined, users are referred to the tables within the FIS. Based on data listed in Tables 10 and 11 of the FIS , and as confirmed with staff from FEMA to clarify some labeling errors in the tables, the revised 1 % stillwater elevation for the Forest River estuary (Transect 27) is 10 feet ' (NAVD88), and the unrounded Base Flood Elevation (1% Annual Chance Total Water Elevation) is 10.5 feet (NAVD88). The Base Flood Elevation of 10.5 feet (NAVD88) (or 11.3 feet NGVD29) is considered the extent of LSCSF under the Wetlands Protection Act for the ' Project site. Based on the preliminary data developed by FEMA the majority of the proposed building demolition work and temporary parking construction will occur in LSCSF. See Attachment E, NOI Permit Drawings. ' The Project is not located within areas Mapped as Priority Habitat of Rare Species and/or Estimated Habitat of Rare Wildlife by the Natural Heritage and Endangered Species Program , under the Massachusetts Endangered Species Act and the Massachusetts Wetlands Protection Act, respectively (Natural Heritage Atlas, 2008). There are also no mapped t potential vernal pools or certified vernal pools in the vicinity of the project area. 3.0 Description of Proposed Work ' The Project consists of razing the existing Weir "Blue" Building and Mackey Building and constructing a parking lot on three properties. Additional site work will include , modifications to the existing stormwater management system, site lighting, emergency phones and a shuttle bus stop shelter. The total estimated limit of work area occupies approximately 237 acres. It is anticipated that the Project will be completed in 2014 over � an approximately 7 month period, beginning in January 2014. Approximately 31,000 s.f. of LSCSF will be temporarily altered by the proposed Project. ' While there are no performance standards for LSCSF identified in the Act, this resource area may be presumed significant to flood control and storm damage prevention (see 310 CMR NOl/SalemStateUniversityCanalStreetParkingCot 1 AttachmentA-Nairative ' Epsilon Associates, Inc. , ' ' 10.24(1)). As the final proposed site grades will remain similar to existing conditions, 2 buildings are being removed from the site, and no fill is proposed, no adverse effects on 1 LSCSF or its ability to provide storm damage prevention and flood control are anticipated. 3.1 Bui/ding Demolition & Removal 1 The demolition plan for the Weir and Mackey Buildings is to terminate existing utility services, raze and remove the existing structures, remove the floor slab, and cut off ' footings/frost walls approximately two feet below the existing ground surface. The majority of existing paved parking and driveways on all 3 lots will also be reclaimed or removed ' with the exception of the existing Stanley Building parking lot which will be retained and expanded upon. Demolition will consist of a controlled take down of the existing structures by means of hydraulic equipment. Both the Weir and Mackey Buildings are stand-alone , structures located far enough away from adjacent properties so as not to require special protection measures for adjacent structures. Demolition of the Mackey Building will require noise and dust control given its proximity to residential properties along Broadway. ' Existing trees will be protected as demarcated on the NOI Permit Drawings (See Sheet C-1.0 — Existing Conditions/Site Preparation Plan). Site preparation and demolition is anticipated to commence during winter 2014. ' The anticipated demolition/construction sequence is as follows: ' • Establish site access and means of cordoning off work areas and protection measures including erection of site construction fencing, installation of , proposed erosion controls and catch basin inlet protection, installation of dust control requirements and temporary water sources. Anticipated start date:January 2014. , • Implement a Demolition Waste Management Plan (e.g., material inventory and characterization, identifying recyclable components, etc). � • Commence demolition activities consisting of a controlled take down by means of hydraulic equipment and removal of all generated waste material ' from the Project site according to Waste Management Plan. The selected Contractor shall dispose of all materials off-site in accordance with applicable federal, state, and local regulations, ordinances, and codes. ' Demolition of the building interiors will be accomplished mostly by hand, possibly some bobcat work, and materials will be loaded into dumpsters at 1 the existing loading docks. Structure demolition will be conducted by excavators. Materials (i.e. concrete, block, metals, wood) will 6e sorted and stockpiled on site within the limits of work and then loaded out, with dust ' control to be utilized as necessary. � NOl/Salem State Unive�sity Canal Street Parking Lot 3 Attachment A-Nar�ative Epsilon Associates, Inc. ' , • Remove building foundations to two feet below proposed grade and ' coordinate any additional removal work (i.e. vegetation; pavement) that may be required to accommodate proposed parking areas. ' • Conduct utility service relocation review and relocate site utility connections (i.e. gas, water, electric, communication) as necessary. There is no ' anticipated need for relocation of existing gas or water connections. • Conduct existing utility disconnect requirements (i.e. cut, cap and make safe ' in accordance with the City's requirements (or utility company). • Conduct parking lot construction, paving, and site stabilization measures. ' Estimated Project completion date: July 2014. See Sheet C-1.0, Existing Conditions/Site Preparation Plan for additional information ' regarding proposed demolition activities. 3.2 Parking Lot Construdion ' The proposed parking lot layout will provide a total of 284 parking spaces on the 3 lots ' collectively; of which 11 will be accessible in accordance with Americans with Disabilities Act ("ADA") requirements (see Sheet C-2.0, Site Plan in NOI Permit Drawings). The proposed additional parking is temporary (for approximately two — three years) and is being ', constructed to mitigate the loss of a 157 space parking inventory on Central Campus at the site of the proposed new student Residence Hall. SSU and MSCBA have initiated a study for a parking garage at SSU that would accommodate up to 800 vehicles on either Central, � North or O'Keefe campuses. When the new parking garage opens the Salem State University Assistance Corporation and SSU intend to develop the Project property for mixed university and private uses as outlined in the December 2008 Sasaki Study' of the Weir ' Property. Project activities proposed in this NOI include the following. The existing Stanley Building , parking area will be expanded onto portions of the Mackey site currently occupied by the building and grassed areas. The existing Stanley Building parking area will be widened to � provide an additional row of parking along a wooded area to the east and the existing pavement will be restriped to provide additional spaces. No expansion of use within the Clover Street right-of-way is proposed beyond those areas of parking and driveways , currently developed for the Mackey and Stanley Building uses. The proposed parking lots will continue to use the existin access oints via the curb cuts on Lorin Avenue and Canal S p B ' Street. A current southern curb cut on Canal Street, which accesses the parking lot near the � Salem State College Loring-Canal Corridor Vision & Weir Property Development Study, Sasaki Associates, ' Inc., December 2008. NOl/SalemStateUniversityCanalStreetParkingCot 4 AttachmentA-Na�rative � Epsilon Associates, Inc. � 1 i 1 existing Weir building entrance, will be discontinued. The existing municipally-owned bike path outside the Project limits will not be disturbed. The existing 9 parking spaces that ' currently extend onto the municipal property that contains the bike path will remain in their present configuration and be incorporated into the proposed parking layout. These 9 ' parking spaces will remain in their current paved condition and are not included in the proposed limits of new pavement. As previously mentioned, utility work for the Project will consist of cutting and capping existing services to the Weir and Mackey Buildings and ', , providing service conduits to the proposed new site lighting, shuttle bus shelter and emergency phones. Proposed site grading will result in minimal changes to site topography. Timber guard rails will be installed as shown on the NOI Permit Drawings. ' Bituminous paving is anticipated to be scheduled as a spring 2014 activity. 33 StormwaterManagementSystem ' The majority of the Project site currently consists of impervious surfaces (i.e. existing pavement and buildings) associated with industrial development. The existing stormwater , management system on the Project site currently consists of surface runoff from existing paved areas, building rooftops and landscaped areas to a network of onsite and offsite catch basins and/or adjacent vegetated areas. The onsite and offsite catch basins are presumed to ' connect to municipal storm drains and the municipal sanitary sewer system. The proposed stormwater management system has been designed to comply to the ; ' maximum extent practicable with MassDEP's stormwater management standards relative to previously developed areas. The grading and drainage approach for this Project is to I ' maintain existing conditions and existing stormwater flow pattems to the greatest extent practicable. Proposed BMPs to accommodate minor changes to groundwater recharge and runoff consist of an infiltration trench with a vegetated filter strip for pretreatment located at the east boundary of the Mackey/Stanley site. In addition, no new outfalls are proposed as � � part of this Project The layout of the proposed system is depicted on the attached NOI Permit Drawings (see Sheet C-2.0, Site Plan). For a more comprehensive discussion of II ' stormwater management refer to the attached stormwater management report prepared by Oak Consulting Group that is provided in Attachment F of this NOI (under separate cover). I ' The report includes supporting drainage calculations prepared by a Registered Professional Civil Engineer of the Commonwealth, a MassDEP Stormwater Management Form Checklist, and a long term operations and maintenance plan. ' ' 4.0 Mitigation Measures ' As described above, proposed Project activities are confined to upland locations comprised primarily of impervious surfaces within a developed, urban environment. With the exception of LSCSF, no work will occur in a wetland resource area or the 100 foot Buffer ' Zone. As such, limited mitigation measures and erosion control devices are proposed. Sedimentation barriers are proposed as shown on the Permit Drawings to protect the municipal bike path from any potential erosion or sedimentation during construction. Catch � , NOl/Salem State University Canal Street Parking Lot � 5 A#achment A-Narrative � Epsilon Associates, Inc. _ . 1 basin inlet protection barriers will be utilized during Project activities. Stabilized ' construction entrances will be establish and maintained during demolition and temporary parking lot construction. An adequate stockpile of erosion control materials will be onsite t at all times for emergency or routine replacement. Stormwater discharges during construction will be managed in accordance with the SWPPP prepared in accordance with the U.S. Environmental Protection Agency NPDES Stormwater Construction General Permit ' for Massachusetts. A copy of the SWPPP is included in Oak Consulting Group's stormwater report. Implementation of the SWPPP will incorporate the sedimentation and erosion ' control measures and other BMPs as shown on Sheet C-3.0 of the NOI Permit Drawings. All barriers will remain in place until disturbed areas are stabilized. 5.0 Conclusions ' The information contained in this NOI sufficiently describes the site, proposed work and the � effect of said work on the interests identified in the Act for LSCSF (flood control, storm damage prevention). No work is proposed within any other wetland resource areas. The Applicant therefore respectFully requests that the Salem Conservation Commission issue an � Order of Conditions approving the project with appropriate conditions to protecl the interests identified in M.G.L. c. 131 §40.
