General Description: The Town of Yarmouth is proposing to create a public park at the 23-acre vacant town-owned property at 669 Route 28 utilizing Zoning Bylaw Section 414 – Village Centers Overlay District (VCOD). The entire property is located in VCOD Village Center 1 (VC1). The proposed public park will include walking trails, native landscaping, children’s play area, kayak launch, space for artist shanties and public art, parking, restrooms, and a large open area for periodic special events, along with associated landscaping, utilities, and site improvements. Although being funded and constructed separately, the permit application includes the future municipal wastewater Pump Station #3 located near Route 28. The existing shellfish upweller on the property will remain. All the proposed uses for the Park including the Pump Station and periodic Special Events are allowed by-right uses within the VCOD VC1. These include N9 – Municipal Recreation Use; N3 – Theatrical Productions, including bands, orchestras and entertainers; N11 – Other miscellaneous amusement & recreation services; and P10 – Municipal use (for the pump station). Although the overall project also includes an elevated boardwalk on the property to the south, this is not part of the VCOD SPR and will require a Special Permit from the ZBA for a Municipal Recreation Use in a residential zone. Please see the attached application materials for additional information. B. Process - VCOD Site Plan Review: VCOD Design Standards per Section 414.8 and the Architectural & Site Design Standards are mandatory for VCOD projects. The Planning Board reviews the project for compliance with these standards, however the VCOD SPR is not a Special Permit Decision and does not grant any zoning relief or make any zoning determinations. Applicants have the right to appeal the decision of the Planning Board to the Zoning Board of Appeals. Any zoning relief required would be done through the Zoning Board of Appeals (ZBA), although none is anticipated. C. Comments from Other Committees: 1. Site Plan Review (SPR): Please refer to the November 22, 2022 SPR Comment Sheet. Many comments from the SPR involve other regulations or codes that the Applicant must adhere to and are not under the purview of the VCOD SPR. Also, as a Town initiative, the project has been reviewed thoroughly by various Town Staff throughout design development and modified accordingly. Separate meetings prior to SPR were held with Police, Fire, Engineering, Water, Planning Division Planning Board 669 Route 28 – Riverwalk Park January 26, 2023 Page 2 of 2 Parks, Public Works, Health, Building, Natural Resources and Conservation. The following outlines the status of various outstanding SPR comments. a. Planning: The miscellaneous design comments from the Town Planner have generally been addressed in the VCOD SPR packet except that the existing hydrant near the Courtland Way emergency access needs to be replaced; and footcandles at the Route 28 driveway entrance cannot exceed 0.5 footcandles per Section 414.8.10.7. The main sign has been modified to include a nautical theme, although the actual name of the park is still to be determined and a sign permit will be required. b. Building: The application materials include a Parking Lot Canopy Calculation on Sheet L1.1 showing the required tree canopy of 30%. Additional review of the VCOD SPR documents was solicited from the Building Commission and he had no further comments beyond the need to reduce the footcandles at the entrance as noted above. c. Conservation: Two Notice of Intents for the project (Riverwalk Park and Boardwalk/ Kayak Launch) have been approved by the Conservation Commission which addressed the comments from the Conservation Administrator. The Stormwater Management Permit Application has undergone peer review and BETA is developing responses. The Chapter 91 License has been submitted to the state. d. Engineering: Ultimately the project will be led by Engineering during the bidding and construction phase of the project and we continue to coordinate with them. e. Fire: Turning templates for fire vehicles have been accommodated. f. Police: The Police Dept was unable to attend SPR but did send an e-mail inquiring about the median island at the entrance and cameras (see attached 11/22/22 e-mail between Lt. Mike Bryant and Town Planner). The center island curbing is fixed and will require traffic management measures during larger periodic events if all three lanes are to be used for exiting the site. BETA is coordinating with Natural Resources/Police and LAN-TEL Communications regarding installation of some cameras on the property. 2. Design Review Committee (DRC): The Design Review Committee reviews VCOD projects for mandatory compliance as it relates to the Architectural and Site Design Standards. Please find attached the January 24, 2023 Design Review Comment Sheet. The DR Comments denote that the DRC felt the project either meets the standards or they are not applicable to the project. They did recommend using one type of siding per building, for example all clapboards for the restroom and all shingles for the Pump Station, rather than varying the materials. 3. Planner Comments: The following is suggested language for consideration by the Planning Board. Motion that the Riverwalk Park project at 669 Route 28 as presented at the Planning Board meeting of February 1, 2023 and in accordance with the plans and materials submitted is in compliance with the VCOD Design Standards, and subject to the following conditions: 1. Install a new fire hydrant near the Courtland Way emergency access. 2. Reduce the footcandles at the property line along Route 28 at the main entrance to 0.5 footcandles in accordance with Section 414.8.10.7. 3. Modify the siding on the Restrooms to be all clapboard style and modify the siding on the Pump Station to be all shingles as recommended by the Design Review Committee. Attachments: 1.

Prepared for: VCOD VC-1 Site Plan Review, Town of Yarmouth January 2023 Yarmouth Riverwalk Park and Event Space Project Narrative Yarmouth, Massachusetts 2 PROJECT OVERVIEW The Riverwalk Park depicted in this plan set is the culmination of over a decade of community outreach and planning work, and the filing of the permitting plans re presents a significant milestone on the path to construction of the project. The Town is proposing to redevelop the Town-owned former Drive-In Theater site located at 669 Route 28 and a portion of the adjacent un-numbered lot to the south into a Riverwalk Park and Event Space for use by residents and visitors (the Project). The Project seeks to improve the existing property through restorative plantings and providing diverse and immersive passive and active recreation opportunities, with public amenities, organized around a large, open grass Event Space. A critical, non-recreational element of the park is Wastewater Pump Station #3, located near route 28, east of the park drive. The collection network and pump station will serve to improve water quality and pump the collected wastewater from a large are a of the community to the treatment plant. The over-arching purpose of this Project is to provide accessible outdoor recreation opportunities to the public, create a new event space for the Town and to restore the degraded waterfront. The Town seeks to embrace and expand the natural beauty of Cape Cod by restoring the underutilized and degraded property to provide new habitat and a scenic, park space with visual and physical access to the water, for both residents and tourists alike. The Project will provide facilities tha t are ADA-accessible, in an area of town that is connected to public transit, with pedestrian and bicycle infrastructure. The Project seeks to expand outdoor recreation for the public, and help the community realize the physical and mental health benefits derived from green space. The project is also intended to be help ignite private sector interest, visitation, and foster revitalization of the Rte. 28 Village Center District. The “Site” subject to this review is the 23-acre former Drive-In property, # 669 Main St., pa rcel 32/122. This site in Zoned B-2, within Village Center Overlay Zone, VC-1, with a minimum lot size of 20,000 sf. The existing parcel 32/122 is 1,015,820 sf . in size and is entirely within the Floodplain: Zone AE BFE 12.00/13.00. The proposed Land Use codes that apply to this site consist of N -3, N-9, N-11 and P-10. It is important to note improvements proposed to this lot support improvements proposed on the adjacent Town-owned un-numbered lot to the south, which is zoned R-25. The proposed improvements on the southern lot consist of a 1,300 lf. elevated boardwalk which may be permitted thru a Special U se Permit thru the Zoning Board of Appeals (Use Code N-9). This application will be filed with the ZBA in February 2023. A Notice of Intent for the Boardwalk has been submitted and the project was issued an Order of Conditions from the Conservation Commission on 01.05.2023. The subject of this application, parcel 32/122 involves the rehabilitation of the currently vacant property and conversion into a public park, featuring a central four -acre open grass multi-use field (Event Space) for periodic outdoor events. The space is framed by open field and woodland walking paths. Near the Parkers River, a nature-based play area for children is planned with play structures and lawn games, along with related site amenities, shade sails, and space for public art including groupings of artist shanties displaying work from artists or vendors. Other improvements proposed include a porous paving parking lot with 88 new parking spaces, site lighting and a seasonal restroom building (1,130 sf), with a small office space and mechanical room. The design of the park on the former Drive-In site also features a boardwalk leading to a zero -entry float for launching canoes, kayaks and paddleboards on the Parkers River . Key project o bjectives include: • Creation of a park access drive to accommodate daily park users (automobiles, vans, busses) as well as increased volume of vehicles entering/existing during per iodic special events. • Creation of emergency vehicle and pedestrian access to/from Courtland Way • Config uring the park drive to allow vehicles with (roof-top) non-motorized personal watercraft to access a proposed kayak/paddleboard launch, for ease of drop-off/pick up. • Providing vehicular parking areas that support visitors that wish to utilize the park walking trails, nature- based play area, kayak launch and visit the artist shanties. • Creation of accessible, interconnected walking paths throughout the park and specifically for access to the elevated boardwalk loop over the salt marsh to the south. • Establishing for the public both visual and physical access to the Parkers River, • Creation of a grassed multi-use open area, w/ supporting utilities, for periodic special events. EXISTING CONDITIONS The Yarmouth Drive-In formerly operated at the site with a footprint of approximately 7-acres of paved parking, connected with a wide paved driveway to Route 28. The majority of the paved surface s have become degraded, broken and crumbled, or are covered with layers of fine sand, with only limited, sparse vegetation. Since the Drive-In Theater closure, the property has been used by the Town for the temporary storage of storm debris, as a staging a rea for construction materials related to the nearby Parkers River Bridge project on Route 28, and for occasional special public events or festivals. Throughout the former Drive-In property, there are areas of previous disturbance with debris consisting of wood piles, steel, tires, household rubbish, and marine materials located near the bank of the Parkers River and in wooded areas around the open area that was the Drive-In Theater Site. Metal, plastic, glass, wire and asphalt can be found across the open area of the Site, and the foundation of the former Drive-In Theater projector house is visible. Overgrown-jeep and footpaths are present throughout the woods to the south of the open area . Limited and undersized utilities exist on site, however there is no wastewater or stormwater management infrastructure present. Extant infrastructure elements that should be noted are as follows: • The Town owned Shellfish Upweller facility is near the Parkers River. It consists of a small 5’x8’ wood shingled shed and adjacent stockade fenced area enclosing several wide, shallow tanks and pumps. The facility has water and electrical power presently which will be disrupted by the planned park construction. The services will be upgrade and the connections restored as part of this project. • Electrical service to the site exists via a series of utility poles and overhead wires , conveying power to the site from Courtland Way. The electric service is inadequate and will not suppo rt the needs of the Event Space. A new underground electric service and transformer will be installed as part of the proposed improvements • Water service is conveyed to the site via Courtland Way, with existing valves, meter pit, fire hydrants and waterlines on site. The service will be reconfigured as part of the proposed improvements. Portions of the Project will occur within the 100-foot Buffer Zone to resource areas as well as the 35-foot and 50-foot Buffer Zones regulated by Federal, State, and local regulations. The existing conditions within large portions of buffer zones generally consists of previously paved/disturbed areas. Portions of the proposed walking trails are located within the Bylaw 50-foot and 35-foot buffer of salt marsh along the Parkers River and the Lewis Pond Marsh area to the south. Restoration areas are proposed within these buffer zones as well as activities associated with upgrading access to the Town-owned upweller facility, and construction of walking trails. Yarmouth Riverwalk Park and Event Space Project Narrative Yarmouth, Massachusetts 4 PROPOSED IMPROVEMENTS The proposed Yarmouth Riverwalk Park and Event Space has been designed to provide both active and passive outdoor recreational opportunities to residents and visitors alike. Improvements include pedestrian, bicycle and vehicular access with parking facilities, recreational areas / features, public amenities, an event space, and landscape restoration. Detailed descriptions of the key project components follow below. VEHICULAR ACCESS AND PARKING F ACILITIES A 1,270+ linear foot paved park access driveway will be provided from the edge of pavement on Route 28 to the proposed southern cul-de-sac. The driveway will be a minimum of 22 feet wide and will expand to three lanes at the entrance at Route 28. This three-lane configuration will allow for both daily convenience by separating left and right turning vehicles, and for flexibility during special events (Lanes could be configured as two entering, one exiting or one entering and two exiting ). The intersection with Main St. is divided by a landscaped media n. The driveway will include two cul-de-sacs; the first, a northern cul-de- sac is centered at Station 6+50 and the second, southern cul-de-sac is proposed at the end of the road at Station 13+00. The driveway design also includes a reinforced turf lane along the eastern limit of the access driveway from Station 3+00 to Station 6+00 for use as a n expanded ‘flex’ lane during periodic special events to assist in efficient traffic management. The proposed drive aisle within the parking area will also be outfitted with five raised crosswalks to ensure safe pedestrian access and circulation within the park. The plan proposes eighty-eight (88) 10’-0” wide parking spaces, surfaced with porous pavement, which are proposed be on either side of the 24’ wide parking lot drive between Stations 7+00 and 12+50. The number of parking spaces was determined based on a use assessment and park pro gram review, discussed in more detail in the Project Traffic Assessment and Technical Memorandum. For additional parking, the western portion of the open grassed area can be configured to accommodate up to 270 vehicles for special events. Reinf orced turf grass areas approximately 6 feet in width are proposed on either side of the 8-foot shared use path loop around the Event Space. The combined width of reinforced turf will provide a nearly 22-foot-wide hardened drive surface for use during the periodic special events and will allow for emergency vehicles to circulate around the site. The public will not be allowed to drive on this loop on a typical day as access will be restricted through installation of removeable bollards along the first cul-de-sac A reinforced turf lane will also be provided in the north-western corner of the Site, connecting to Courtland Way for use by emergency vehicles. This access way will be outfitted with a locked barrier gate to prevent vehicular access the Site from Courtland Way. A 10-foot-wide stabilized aggregate access path is proposed from the parking area to the existing upweller This driveway will improve the existing rutted and unstable condition of the current upweller driveway and will create a turn around and 2-parking space area for operations staff at a greater distance from the Parkers River than exists today. BICYCLE AND PEDESTRIAN FACILITIES Walking Paths - Looping Walkways are proposed throughout the park, including: • An 8-foot-wide hot-mixed asphalt (HMA) shared use path (SUP) brings both bicycles and pedestrians into the site from Route 28, along the western side of the park access driveway, then continue around the grassed/open space area to provide a looped trail, tying back to itself just south of the restroom building. • A 6-foot-wide stabilized aggregate walking path is proposed to extend from the northern cul -de- sac to the kayak launch, ultimately connecting to the 8-foot-wide SUP. This path will travel along the eastern limit of the Site near the Parkers River and provide access to the artist shanties, natural play area, and Riverwalk Spur trail. • Another 6-foot-wide stabilized aggregate walking path is proposed to the south of the 8-foot-wide SUP into the woods to the south of the event space, eventually branching into two trails that extend to meet the proposed boardwalk. These trails generally follow the overgrown existing walking trails within the woods. • Finally, a 3-foot-wide stabilized aggregate walking path is proposed as a nature path that will travel along the Parkers River from the natural play area to the kayak launch. STRUCTURES Wastewater Pump Station No. 3 - This structure is proposed as part of the larger, phased Town-wide wastewater project. The design of the Riverwalk Park has been developed in coordination with the development of the proposed pump station (PS#3). The design of the park’s stormwater management system accommodates all the anticipated runoff from the pump station building, utility area and driveway. The pump station is a purpose-built building housing large electrical motors, pumps, switching equipment, valves, filters and ventilation systems with generators and odor control equipment in the fenced service yard immediately outside the structure. The pump house is located at the entrance of the park, east of the entrance drive. The structure is positioned in this location based on design parameters such as the planned sewer network, wastewater pumping distances and system-wide low-points, which are all factors that dictate the optimum location for the necessary pumping facilities. The proposed building is approximately 28 feet high, 42 feet wide and 49 feet wide. The facility will not be open to the public but will provide a critically important benefit to community water quality and overall environmental health. A sanitary sewer force main will be installed as part of the planned park improvements, connecting the proposed restroom to the proposed pump station, eliminating the need for onsite septic treatment. The pump station building will be built on a deep concrete foundation. The shell is clad in cement fiber resin trim and gray cement fiber resin clapboard siding, or gray cement fiber shingles as indicated on the plans. The windows will be aluminum clad wood white, with insulating glass. The roofing will be dark gray asphalt shingles. Public Restroom - An ADA-compliant, restroom building with a small office is proposed near the center of the site. The restroom will be approximately 25 feet wide, 44 feet long, approximately 15 feet high with a cupola. The building shown in the plan set was designed jointly with Romtec* a company that designs, engineers, manufactures and supplies prefabricated buildings for an array of applications. The building for Riverwalk Park project is a standard Romtec building type, then modified to meet the Project needs. During final design the plans will have additional details added to them and will be finalized and sealed by the Romtec team architect. This will be required in order for a building permit to be obtained. *More information is available at https://romtech.com. Yarmouth Riverwalk Park and Event Space Project Narrative Yarmouth, Massachusetts 6 Public Restroom (continued) The foundation will be constructed on structural fill, with cast-in-place concrete frost walls. The restroom structure will be constructed of concrete masonry units (CMU) with wood trusses and exposed T&G wood roof planks, overlaid on the exterior with architectural asphalt roofing shingles. Siding will be light gray fiber cement board clapboard siding and trim, with stained na tural wood cedar shingles accents in the gable ends. Downlights will be installed within the overhangs, with minimal sconce lighting. The building will have a small o ffice/storage area , an electrical/mechanical room, men’s restroom (two toilets and three urinals), and woman’s restroom (five toilets). The restroom will be for seasonal use, without heating or cooling, but will have an active ventilation system. A new water service will be brought to the building. Water will be heated with electric tankless w ater heaters. The structure as proposed is sited upon a built-up, gently shaped landform, with two sets of concrete stairs and a ADA compliant sloped walk providing access to the building from the surrounding park. The finish floor is set at Elevation 12.00. Even at this elevated height, the structure will be within the 100-year floodplain (Elevation 13.00). As such the building will be dry-flood-proofed with stop-log weir flood protection at each exterior doorway . This manually installed flood protection will extend at a minimum to Elevation 15.00 (two feet above the Base Flood Elevation). All windows are set above Elevation 15.00. The sanitary sewer service for this building will be provided in phases. Initially, while the PS#3 is under construction (separate construction contract) a subsurface 5,000 gallon “tight -tank’ will be installed east of the restroom which will be pumped on a regular schedule by a contracted sanitary sewer service vendor until a point in time when the pump station is on-line. In the final condition, wastewater from the restrooms will be pumped from the ‘tight-tank’ to the new Wastewater Pump Station #3 proposed just east of the Site entrance drive on Route 28. The Riverwalk Park Project includes the instal lation of the 5,000 gallon ‘tight tank’ and the force main sewer line connection to a termination point just outside the future pump station. The connection will be finalized upon completion of PS#3. Artist Shanties – The Project also includes the installation of ten (10) concrete pads, for up to nine 120 sf temporary artist shanties, so local artisans, craftsmen, vendors can sell their wares. These shanties are proposed east of the parking area and west of the upweller. The light-weight wood frame structures will be anchored to the concrete slabs, and will be constructed of approved flood resistant materials, approved for use in this location. In addition to the shanties, the tenth concrete pad location is provided for the installation of a kayak launch kiosk of generally the same size and appearance. RECREATION /AMENITIES Kayak Launch – East of the southern cul-de-sac is the proposed boardwalk approach to the kayak/paddleboard float /zero -entry launch. As noted above, the Project proposes installation of a kiosk for the support of water-based activities, and or kayak and paddleboard rentals. There are nearby grassed areas for staging outings, flanked with nearby town owned storage racks. Play Area - A nature-based play area is proposed to the east of the parking area. This play area includes a over-size swing, two colorful embankment slides, a climbing slope, a pirate ship play structure, 3-foot- diameter play tunnel, two ADA-Accessible picnic tables and sloped walkways, interesting landforms, and extensive planting beds. Site Lighting – Lighting will also be provided primarily through installation of approximately 3 6 ‘Type A’ lights, utilizing the same luminaire as found on the reconstructed Parker’s River Bridge. These are fixtures associated with the roadway and paths . The plans include 12 ‘Type B’ light fixtures configured with cut - off optics (dark sky friendly, eliminates light trespass) placed as perimeter lights located at the edge of the event space. Type B lights will be illuminated only during periodic special events. The ‘Type A’ fixtures will be installed along the entrance drive and shared-use-path adjacent to the restrooms, and along the parking area. All fixtures will be LED and operate at 3000k, which emits a warm color light. The lights will have adjustable power to allow for a (programmable) reduction of output late at night to reduce un- necessary light. Related Improvements - The park design features interconnected ADA compliant looping trails, and walkways, a series of large open areas for flexible use and a series of outdoor “rooms” with space for public art installations, displays, and exhibits. The Project has also incorporated educational and interpretive graphic panels for visitors . Additional amenities at the park will include woven fabric shade structures, seventeen (17) benches scattered throughout the park, five (5) trash receptacles, two multi - bike racks accommodating six bikes per rack, and three double bike racks. EVENT SPACE The proposed large multi-use grass open space will be available to the public for general recreation however, this area may be used periodically for special events. Vehicular access and egress during these events were described on the proceeding pages. The location and orientation of a specified “Stage” area was evaluated and determined based on potential noise impacts to neighbors. Based on this evaluation, any temporary performance stage will be located near the entrance to the woodland trail, and noise will be projected toward Route 28. The stage area will be oriented generally to face a 200’ by 200’ primary audience seating / lawn area. The Event Space has also been designed with electrical panel boards/load centers to service events, electric receptacles that can be used by food trucks or other vendors, and water service connections. The overall design leaves space for portable restrooms to be arranged for the periodic special event spac e. SITE UTILITIES The site is presently serviced with electricity and Town water. Water - The water service connection will be maintained at Courtland Way. However, all new water lines will be installed, with the main extended to both the proposed restroom mechanical room as well as two new hydrants. Water service to yard hydrants located on the site will be distributed from the mechanical room. New water lines will be brought to the existing Upweller. Electric /Cable/Data - Electric Service will be completely upgraded from the service that exists presently. Three phase electrical power will be brought into the site from the north side of Main St. It will be routed thru electrical manholes and carried in several conduits underground to a n above ground transformer located on the Northwest side of the proposed restroom building. Power will be brought into mechanical room within the restroom and then redistributed to areas of the site , including two load centers at the edges of the event space. A new electric feed will be brought to the existing Upweller. Cable/Data wiring will be brought into the site in a similar manner, following the same route as the electrical service. Sanitary Sewer - The project proposes a 5,000-gallon sanitary sewer tank with a force -main line installed underground connecting the restroom to the proposed Wastewater Pump Station No. 3 (PS#3). The tank will function as a ‘tight-tank’ in the short term until PS#3 is constructed and the treatment plant is on -line, anticipated to be in 2026-2027. When available the ‘tight tank’ will be equipped with the required macerator and pump equipment converting it to the Restroom Pump Chamber. Once connected, regular pumping of the ‘tight tank’ will no longer be required Stormwater - A comprehensive, low impact Stormwater Management System has been designed for the Riverwalk Park. The entire site has been graded to direct runoff from impervious surfaces towards the Yarmouth Riverwalk Park and Event Space Project Narrative Yarmouth, Massachusetts 8 proposed infiltration basins, following Best Management Practices (BMPs). The design meets all the requirements of the Massachusetts Stormwater Standards . Once built, there will be a significant reduction Stormwater (continued) in stormwater peak flow rates and runoff volumes directed towards the river than presently occurs under the existing , degraded conditions. No runoff from any impervious surfaces as defined by the Standards will flow untreated towards the Parkers River. The following Stormwater BMPs have been incorporated into the Project Design: • The proposed grassed field/open space has been graded to include two low points that will function as infiltration basins that will collect and treat runoff from the perimeter walkway around the Site. Pretreatment for these “basins” will be provided by the surrounding grass which will act as a vegetated filter strip. • The parking areas surfaced with porous pavement will treat driveway runoff. A collection trench will be provided at the outside edge to collect excess runoff and direct it into the pavement base. • An infiltration basin with two forebays is proposed at the southern limit of the southern cul -de- sac, near Sta. 13+00 to treat runoff from the cul-de-sac, kayak storage area, and rental kiosk. • A vegetated swale is proposed along the southern limit of access driveway from Sta. 2+50 to 6+00 that will collect stormwater and provide pretreatment prior to discharge into a subs urface infiltration chamber system that will be located beneath the entrance driveway to treat runoff from this area. • A second sub-surface infiltration system is proposed south of the proposed restroom. This system will treat runoff from the roof of the building and surrounding walkways. LANDSCAPE The approach to the Landscape Design of Riverwalk Park was developed with an emphasis on restoring degraded areas of the site and utilizing native plant materials to re -establish habitat and create a naturalized park.

All RA Restoration is proposed within existing degraded RA in accordance with the requirements at 310 CMR 10.58(5). Restoration of these areas includes planting of native species appropriate for the ecological conditions at the Site. Previous inspections of the Site revealed e xtensive invasive vegetation growing along the Parkers River, in previously degraded areas. The Project proposes removing invasive species, including Autumn olive, (Elaeagnus umbellate ), Bush honeysuckle (Lonicera spp.), Multiflora rose (Rosa multiflora) and Japanese knotweed (Fallopia japonica) along with others. The construction contractor will be responsible for providing a detailed Invasive Species Control Plan. It is anticipated that the methods of control will include mechanical removal, and use of herbicides. Following removal of the invasive species, these areas will be stabilized with native vegetation, as detailed on the Project plans. Salt Marsh Approximately 1,575 sf of salt marsh will be restored along the Parkers River where pavement will be removed, and the area will be reestablished with salt meadow grass (Spartina patens) and high tide bush (Iva frutescens). Landscape Maintenance - The overall design approach to the Riverwalk Park has been to minimize hardscape improvements along with any c oncentrated rainwater runoff, restore areas previously modified and degraded by human activity, and augment the restored areas with predominantly native plant materials throughout the site. After successful plant establishment the majority of the native grass, perennial, shrub and tree plant material proposed for use on site will not require extensive maintenance. Certain areas of grass may be cut annually to improve the seed bank and facilitate the identification and management of any potential invasive plants. Certain grass species may benefit from cutting back by hand on a yearly basis during the dormant season to improve appearance and re-invigorate growth and spring ‘green-up’. Areas of maintained grass, such as the Event Space will require regular mow ing as the space is programmed for events. For maintained grass areas, a cutting height of 3” is recommended. It may be possible to ‘relax’ a traditional weekly mowing operations during periods of time if special events are not scheduled. This practice would serve to conserve rainfall and promote more robust turf -grass root development. Subsequent mowing operations then would be scheduled well in advance of any event and grass clippings removed. Mulching clippings would be preferred practice with regular mo wing operations. Under concentrated use as associated with special events, both spike and core aeration operations will be required to promote root zone health for all maintained grass areas. The application of well-aged compost thru top-dressing operatio ns in conjunction with aeration is recommended. It may be necessary to supplement the above listed practices with fertilization. A carefully balanced grass care program that includes spring and fall season work as well as planned incremental applications will help ensure no adverse impacts from supplemental nutrients to water quality, groundwater and tidal areas. Any fertilizer or lime applications will be conducted as needed and in accordance with manufacturers recommendations. It is suggeste d that all work related to the health of the grassed areas occur between mid-April and the end of October in any given year. Proper measures to be implemented will seek to limit the adverse impact of insecticides and pesticides. The presence of these chemicals in stormwater runoff has a direct impact on the health of aquatic organisms and can present a threat to human health through groundwater contamination. The major source of these chemicals in stormwater runoff is the application of products designed to kill insects and weeds in the lawn area. The use of herbicides will be limited to invasive species control as part of the Invasive Plant management operations and will be by direct application only rather than broadcast applications. Insecticides will not be used on site. CONSTRUCTION PHASE Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan has been provided as part of the stormwater report and a Draft Stormwater Pollution Prevention Plan (SWPPP) has been prepared. Erosion and sedimentation controls will be installed and maintained where activities are proposed adjacent to BVW, IVW, Coastal Beach, Riverfront Area, Salt Marsh, and/or LSCSF. Fencing and the specified erosion controls will provide a distinct limit of work barrier while preventing silt and sediments from migrating into or towards the coastal resource areas. These measures include installation of compost filter tubes and silt sacks (catch basin inlet protection measures). During construction, the contractor will also be required to minimize airborne particulate matter through dust control to prevent impacts to public health. SUMMARY The proposed Yarmouth Riverwalk Park will create a new waterfront accessible destination for active and passive outdoor recreation for the public in the Town of Yarmouth. The park will provide a space to hold periodic special events and contribute to the town’s goal of improving the Village Center and degraded Riverfront Areas. The Project has been designed to protect resource areas during and following construction and has avoided and minimized impacts to the greatest extent practical, while still meeting the Town’s coastal redevelopment goals. The Project design meets performance standards for all resource areas present within the limit of work, as set forth in the Wetlands Protection Act and its Regulations at 310 CMR 10.00. Separate permit applications that have been filed include local Stormwater Management Application, Site Plan Review, Water quality certification, Notice of Intent filings, USACE Preconstruction Notification and DEP Chapter 91 License. The project has been thru Site Plan Review and comments ha ve been issued. Two NOIs have been filed, one for the work over resource areas and a separate one for the park. On 01.05.23 the Conservation Commission issued the Order of conditions for the Boardwalk and the Park site NOI review is nearing completion and it is anticipated that the issuance of the Order of Conditions for the Riverwalk Park improvements will occur by the end of February, 2023. The stormwater management permit was filed in November 2022, along with the extensive supporting documentation required. It includes information on stormwater flow, discharge volume, design storm frequencies, soil percolation rates and Hydro CAD runoff calculations. Permanent alteration of Riverfront Area (RA) and LSCSF be mitigated through restoration of degraded Riverfront Area within the 100 -foot inner riparian zone with native vegetation, removal of invasive species, and installation of stormwater management Best Management Practices (BMPs). Mitigation has also been included to offset the Project’s impacts on wildlife habitat, air quality, water quality, public infrastructure, noise and visual impacts, and the heat island effect.
