Comprehensive P l a n z o z z <br /> (DRAFT 03/1.8/22) <br /> Mashpee is classified by FEMA as a High-Risk Coastal Area (VE), a Regulatory Floodway(AE), or a 0.2% <br /> annual chance flood areas(X)within the town (MassGIS, 2017). <br /> Article XI in the Zoning Bylaw covers the Floodplain District, which includes all Special Flood Hazard <br /> Areas (SFHAs)within the town designated as Zone EA or VE on the Barnstable County Flood Insurance <br /> Rate Map (FIRM) issued by the Federal Emergency Management Agency(FEMA)for the administration <br /> of the National Flood Insurance Program(Town of Mashpee, 2021).These are locations where the NFIP's <br /> floodplain management regulations must be enforced because they are within the land area covered by <br /> the floodwaters of the base or too-year flood (Federal Emergency Management Agency). <br /> Flood Map is needed in this section.We will map this information through MassGIS Data: FEMA National <br /> Flood Hazard Layer. <br /> Parcels and buildings vulnerable to flooding were identified in the 2017 Hazard Mitigation Plan Draft.The <br /> plan identified 19% of the parcels in the A zone and 4.6% of the parcels in the V zone (Cape Cod <br /> Commission, 2017). Infrastructure that is vulnerable to the impacts of flooding was also identified in the <br /> 2017 Hazard Mitigation Plan. These areas include several culverts, parts of Great Neck Road South and <br /> Great Oak Road, Route 28 east of the rotary,and the School Street Bridge(Cape Cod Commission, 2017). <br /> Additionally, the Municipal Vulnerability Preparedness (MVP) Planning process identified existing <br /> development in vulnerable floodplains,as well as coastal and stormwater flooding of low-lying roads and <br /> culverts, including Brook Road crossing Red Brook and Great Oak Road adjacent to Jehu Pond (Woods <br /> Hole Group, 2020). <br /> 4.2.4 Surficial Geology <br /> The landscape of Barnstable County consists of glacial landforms from the last ice age. The moving ice <br /> scraped bedrock from southern New England and deposited it as glacial sediment in Cape Cod (General <br /> Geology of Barnstable County, Massachusetts). Kettle holes were formed from blocks of ice left behind <br /> by retreating glaciers (Town of Mashpee, 2008).As a result, steep slopes began to collapse around their <br /> edges and formed a more gentle grade (Town of Mashpee, 2008). Sea level rise, resulting from the ice <br /> gradually melting, resulted in freshwater reaching the ground into porous outwash sediments (Town of <br /> Mashpee, 2008). Mashpee consists of gravelly pebble to cobble-sized gravel typical of outwash plain <br /> (Town of Mashpee, 2008). In addition to sand and gravel,the New Seabury and Popponesset Beach areas <br /> consist of boulders and larger stones. (Town of Mashpee, 2008). <br /> 4.2.5 Soils and Vegetation <br /> The town is surrounded by pines and oaks indigenous to the area. In addition to the pine trees and scrub <br /> oak, the Mashpee Pine Barrens,the Mashpee River Woodlands, and the Besse Bog consist of rare plant <br /> species. These areas are further detailed in the Open Space and Recreation chapter of this <br /> Comprehensive Plan.The Mashpee Pine Barrens have pockets of Atlantic white cedar swamps that grow <br /> in sandy glacial deposits with standing water (Town of Mashpee, n.d.). The Mashpee River Woodlands <br /> include pine and oak forest, an understory of huckleberry, inkberry, and sheep laurel (Town of Mashpee, <br /> n.d.).The eastern white pines are the most common trees found in this conservation area (Town of <br /> Mashpee, n.d.).The Besse Bog is home to the rare pink lady's slipper,which is found on acidic soils, and <br /> made up of mixed forest and freshwater wetlands.
