Introduction Cape and Islands Engineering, Inc. submit this Notice of Intent (NOI) Application, on behalf of the applicant and owner, Zach Barber of Harbour Haven Association, Inc., who proposes to construct drainage improvements and provide approximately 270 cubic yard (cy) of sand nourishment including the creation of a berm to address the flooding and erosion concerns at 26 Grandview Drive. The property is located along the western shores Bass River and the proposed work will fall within of Land Subject to Coastal Storm Flowage (LSCSF), Coastal Beach, Riverfront Area, and within 100-feet of jurisdictional wetland resource areas. 1.2 Applicable Regulations This application has been filed in accordance with the Massachusetts Wetlands Protection Act, (MWPA, M.G.L. Chapter 131, Section 40) and its implementing regulations (310 CMR 10.00), the Yarmouth Wetlands Protection Bylaw (Chapter 143) and implementing regulations. 2.0 BACKGROUND 2.1 Existing Conditions The project site at 26 Grandview Drive Yarmouth, is a private residentially zoned undeveloped beach lot with frontage of Bass River to the east. The 11,034 square foot (sf) lot contains a small paved parking lot with a sewer drain, maintained beach, and small areas of natural vegetation. The site is generally flat to slightly sloping towards the shoreline. The site experiences flooding and poor drainage along the western portion of the lot that flood the road along Grandview Drive. The existing installed drainage system handles most rainfall events however if the capacity of that system get overwhelmed, ponding of stormwater eventually overflows onto and washes out the existing beach lot. Developed residential properties border the site to the north, west, and south. 2.2 Property History The lot has been on record with the Town Assessors since 1966 and registered at the Barnstable Registry of Deeds under Document #107951. No known environmental permits have been issued for the property. 2.3 Site Resources Jurisdictional resources areas were delineated and located by an on the ground instrument survey and shown on the project plans. The resource areas identified on or within 100-feet of the property include Coastal Beach, Land Under the Ocean, Land Containing Shellfish, Banks of or Land under the Rivers that Underlie Anadromous/Catadromous ("Fish Run"), Land Subject to Tidal Action, Land Subject to Coastal Storm Flowage (LSCSF), and Riverfront Area. Refer to Section 5.0 for the analysis of performance standards associated with directly impacted resource area. According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Community Panel #25001C0591J, effective date of July 16, 2014, the property is located within the 100-year floodplain defined by FEMA Flood Zone AE (EL. 11) and AE (EL. 12). NOTICE OF INTENT APPLICATION 26 GRANDVIEW DR., YARMOUTH Project Narrative Page 3 The Massachusetts Natural Heritage and Endangered Species Program (NHESP) Atlas (15th edition, August 1, 2021) and MassGIS online were consulted, and the project site is not located within the Pleasant Bay Area of Critical Environmental Concern (ACEC) nor within NHESP mapped habitats. There are no vernal pools within 100 feet of the site. 3.0 PROPOSED PROJECT 3.1 Scope of Work The applicant has designed a re-nourishment and berm with overflow conveyance plan to protect the area from flooding, erosion, and other damage associated with major storm events. This work will be carried out across about 7,300 square feet (sf) of the beach lot that has repeatedly eroded over the years. The design proposes to re-nourish this area with approximately 270 cy of compatible sand including the construction of a six-foot wide earthen and vegetated berm along the parking lot with a four-foot high sand fence. The berm and nourishment will be considered as a first phase for the project and will be monitored and inspected after storm events. A concrete weir overflow structure is to be installed at the south-easterly edge of the parking lot. The weir structure will allow a certain level of ponding to occur in the parking lot, then when needed will safely outlet additional runoff into a six-foot wide vegetated conveyance swale. The swale will allow excess runoff to infiltrate and convey away from the parking area and ultimately toward Bass River. 3.2 Construction Methodology Prior to the start of construction, the Order of Conditions (OOC) and MA Department of Environmental Protection (MA DEP) / Falmouth Conservation Commission File Number will be posted at the site, and the area will be staged for construction. The project has been designed to incorporate construction methodologies and measures that will result in an overall benefit to the resource areas. Access to the work areas will be from Grandview Drive and equipment will be stored away from resource areas to the greatest possible extent. Similar to previous beach nourishment work, sand will be acquired from an upland source and delivered to the site parking lot via 10 or 20 yard dump trucks. The beach nourishment sand will be loaded into a front-end loader in the parking lot, and spread to the elevations as shown on the design plan. Common borrow fill will be imported to create the earthen berm along the parking lot edge. The berm will be shaped and graded per the site plan and will be loamed, seeded and planted. All work will be carried out above mean high water and within the limit-of-work as delineated on the planting plan. The Coastal Beach is not significant to the interest under the WPA and the project aims to enhance the area ability to redirect flood waters and prevent damage associated with storm surges. The proposed project will enhance the beach and provide sediment to the existing beach system. The swale will allow for improved drainage flow if the existing underground infiltration system gets overwhelmed and the sand nourishment and berm will further protect against flooding and prevent the erosion of the beach. The work was designed to protect the interests of the Wetlands Protection Act. 3.3 Anticipated Impacts Work will take place within Coastal Beach, LSCSF, and within 100 feet of jurisdictional wetland resources. No adverse impacts to resource areas will occur as a part of the project. Rather, the project serves to restore eroded portions of the bank and enhance resource areas to better protect against tidal action and storm surges. All impacts will be temporary within previously maintained and legally altered areas. NOTICE OF INTENT APPLICATION 26 GRANDVIEW DR., YARMOUTH Project Narrative Page 4 4.0 MINIMIZATION AND MITIGATING MEASURES 4.1 Minimization Measures Best Management Practices have been included in the plan notes in order to avoid and minimize impacts to resource areas. Prior to the commencement of any project activities, the work limits and the mean high-water line will be identified to avoid placement of material or equipment below the mean high tide line. During the work, the site will be kept clean and disturbance to adjacent areas will be avoided or minimized to the maximum extent practicable. All ground disturbances will be kept to the minimum necessary to complete the construction and installation(s). Disturbed areas will be stabilized to prevent erosion. Equipment will not be allowed to work in the water or below the mean high tide line. Any temporary disturbances will be restored to preconstruction conditions after work is complete. Upon completion of construction and site stabilization, the sediment and erosion controls will be removed and properly disposed. 4.2 Mitigating Measures No mitigation is proposed as a part of this project, however native coastal plantings are proposed to stabilize the swale outfall. Native plantings and details can be found on the attached plans. This proposal includes improvements to the residential property related to storm damage prevention, flood control, and erosion control. 5.0 APPLICABLE PERFORMANCE STANDARDS The following is a discussion of how the proposed project meets the MA WPA and Town of Yarmouth Wetland Protection Regulations (YWPR) performance standards for each resource area impacted as a result of the project activities. 5.1 Buffer Zone & Buffer Strip Definitions and performance standards for buffer zones are defined locally in YWPR Part 6. The area referred to as “Buffer Zone” extends 100-feet landward of the Coastal Beach resource boundary. All of the proposed work falls directly within resource areas and no adverse effects are expected to the buffer zone or adjacent properties. Construction equipment and crews will traverse the buffer zone along existing paved road and parking lot to perform the work. The 50-foot Buffer Zone will be preserved under current conditions. There will be no increase in impervious surfaces and therefore no mitigation is required. The swale will be constructed of loam, seed and plantings and is intended to be semi-permeable with native plantings to direct flood waters back towards Bass River. There will be no cutting of vegetation and all the trees on the site will be preserved. The proposed project activities will not have an adverse effect on the resource area buffer zone or buffer strip. 5.2 Coastal Beach Definitions and performance standards for Coastal Beach are set forth in 310 CMR 10.27 and YWPR 4.02. The majority of the lot is considered Coastal Beach and generally not significant to the interests protected under the WPA and local regulations. The small, maintained beach lot is located within a developed neighborhood and serves as beach access for private local association residents and is not significant wildlife or bird nesting habitat. Current flooding issues suggest the area is not significant to storm damage prevention or flood control, rather contributing to it. The Coastal Beach does not supply sediment to dunes or other beaches and the area sees a greater loss of sand than replenishment. The NOTICE OF INTENT APPLICATION 26 GRANDVIEW DR., YARMOUTH Project Narrative Page 5 lot is not significant shellfish habitat above MHW according to Shellfish Suitability Areas on MassMapper. Work within Coastal Beach includes adding 270 cy of sand nourishment that will be used to re-nourish the beach and create the sacrificial berm. The nourishment, of compatible grain size, will be imported from an approved off-site local source. Nourishment material grain size shall be reviewed by the Engineer and Conservation department prior to plavement. Best management practices will be implemented to avoid adverse impacts, and no work will be done below mean high water. The implementation of sand nourishment and swales will avoid the existing patches of natural vegetation and the tree near the parking lot will be preserved. The proposed work will not remove substrate, rather replenish it for increased storm damage prevention and flood resilience in congruence with the interests of the WPA. The work will not interfere with the natural movement of the beach of downward drift of sediment. The proposed work will not adversely impact water circulation, distribution of sediment, or water quality. Any temporary disturbances to Coastal Beach will be restored by raking the beach and removing any rutting caused by equipment. The proposed project activities will not induce any impairment of the Coast Beach functional characteristics of Coastal Beach. 5.3 Land Subject to Coastal Storm Flowage (LSCSF) Definitions and performance standards for work within LSCSF is defined locally in YWPR 4.10. The entire property is located within LSCSF as mapped by FEMA Flood Zones AE (E.L. 11) and AE (EL. 12). All of the proposed work will occur within LSCSF. All of the proposed work falls within LSCSF across approximately 8,378 square feet. The work does not fall within the FEMA Flood Zone V. The project area is not located along the eroding shoreline, according to the Massachusetts CZM Shoreline Change Analysis Project mapping tool. The proposed work within the LSCSF area has been designed not to: reduce the ability of the land to absorb and contain waters, reduce the ability of the land to buffer against flooding and wave damage, damage other structures, pollute waters, reduce the area’s ability to provider for wildlife, increase the elevation of velocity of flood waters, or prevent the migration of resource areas due to sea level rise beyond existing conditions. Rather, the addition of beach nourishment is meant to restore the area to conditions prior to over wash and erosion and improve overall flood resilience. The area is prone to flooding along the western portion of the lot near the parking lot as well as surrounding properties and there is no effective drainage. The proposed overflow swale would divert flood waters AWAY from buildings and protected areas and back towards Bass River. The work would provide storm damage protection for the parcel and abutting developed properties while also installing native plantings. The small, maintained beach lot is not a significant wildlife habitat or migration corridor within the fully developed neighborhood. The work shall generally preserve and enhance natural conditions. The proposed work will not otherwise impair the function of the resource areas or result in interruptions to the flow characteristics of flood waters. 5.4 Riverfront Area Performance standards for work related within 200-feet of a river or stream is defined in 310 CMR 10.58. The proposed sand nourishment and swale construction work is significant to the storm damage prevention and flood control for this lot and surrounding developed properties. The maintenance is critical to the safety of the property and protection to nearby wetland resources. The area is experiencing flooding, poor drainage, and a continuous loss of sediment without replacement. The proposed scope has been assessed as the preferred alternative to address the issues at hand while protection the interested of the WPA. NOTICE OF INTENT APPLICATION 26 GRANDVIEW DR., YARMOUTH Project Narrative Page 6 The following alternatives were assessed: • No Action: A No Action alternative would leave existing conditions unchanged and avoid short-term construction disturbance; however, it does not address ongoing stormwater management deficiencies or active beach erosion. Uncontrolled surface runoff would continue during storm events, contributing to flooding issues and sediment loss, ultimately allowing erosive conditions to persist along the shoreline. This alternative provides no improvement in flood resiliency and increases the likelihood of future stabilization efforts that could result in greater impacts to coastal resource areas. Over time, continued erosion and unmanaged runoff may adversely affect sediment distribution and exacerbate flood-related damage, making this alternative inconsistent with the project purpose and less protective of Riverfront Area functions. • Additional Subsurface Drainage Infrastructure: The site has an existing subsurface drainage system that appears to function well. Water does drain down during storm events however the system can be overwhelmed in flash flooding scenarios. This type of system is also prone to clogging and or failure in areas where sand and silt may be able to get into the system. This coastal area subject to wind blown sand a silt, is one of those difficult to manage areas. Proposing additional subsurface structures is a very costly option that could be prone to failure, and still may not be able to handle a flash flood type event. This alternative does not offer the same sediment management or erosion control benefits as the preferred surface- based approach. • Nourishment & Improved Drainage (Preferred Alternative): The proposed design is the preferred option as it provides an effective and economical solution to improve stormwater management while enhancing beach stability. Targeted beach nourishment increases sediment volume within the active coastal system, while the rip rap–lined surface drainage system safely conveys stormwater during peak events, reducing runoff and erosion/sedimentation events. This alternative improves flood resiliency by providing a practical emergency overflow pathway that remains functional in a sandy coastal environment. Construction impacts are limited in extent and duration, minimizing disturbance on the small lot. The project maintains existing hydrology, supports natural sediment distribution, and avoids channelization, resulting in no significant adverse impact to Riverfront Area functions and values. 6.0 SUMMARY 6.1 Performance Standard Metrics The existing wetland resources and anticipated project impacts have been fully documented within this Notice of Intent application. Based on the information provided in this application it is asserted that the following project features would result in a benefit to the associated resource area and will not have an adverse effect on the subject resource area(s) values and functional characteristics. The project should be approved for the following reasons: • The beach nourishment and overflow conveyance project will enhance the area’s ability to protect against flood and erosion events affecting the neighboring properties. • Sand nourishment will be of compatible grain size as currently found within the existing adjacent beach areas and the implementation of coastal plantings will serve as a net improvement to resource conditions. NOTICE OF INTENT APPLICATION 26 GRANDVIEW DR., YARMOUTH Project Narrative Page 7 • Alternative solutions were reviewed and the preferred options is believed to be the best solution that offers the greatest flood protection to the area while having minimal adverse impacts to resource areas. The project conforms to the Massachusetts Wetlands Protection Act, (MWPA, M.G.L. Chapter 131, Section 40) and its implementing regulations (310 CMR 10.00) as well as both the Town of Yarmouth and Town of Yarmouth Wetlands Protection Bylaw and implementing regulations and will not cause unacceptable significant or cumulative effect upon the resource area values. 6.2 Request for Order of Conditions The Applicant has demonstrated and documented evidence that this project meets or exceeds all the relevant performance standards set forth in the governing regulations and respectfully request this project be approved and that an Order of Conditions be issued to the applicant through its representative. 6.3 Contact Information In an effort to reduce the amount of paper required for filings, the entire application can be emailed upon request to regulatory staff and commission members.
