Potential Sump Conditions

<div style='text-align:Left;'><div><div><p><span><span>The Potential Sump Conditions layer is the result of analysis performed on the 2018 Light Detection and Ranging (LiDAR) derived, Bare Earth Digital Elevation Model (DEM) and LAS Dataset. Please see the Data Capture Methodology section of this document for detailed information on how this dataset was created. This dataset is intended for internal use to aid in the following use cases:</span></span></p><ul><li><p><span><span>Tool to assess existing site conditions when responding to service requests for structural, yard and road flooding.</span></span></p></li></ul><ul><li><p><span><span>Tool to assess existing site conditions and potential impact of localized change in topography during redevelopment on adjacent properties if in sumps.</span></span></p></li></ul><ul><li><p><span><span>Tool to assess potential impact of overwhelmed stormwater inlets in sumps on adjacent structures due to ponding of stormwater runoff.</span></span></p></li></ul><ul><li><p><span><span>In concert with other spatial and field information, tool to prioritize sump conditions where structures may potentially be impacted based on depth of ponding, overland drainage area, and elevation of ground-level openings in structure.</span></span></p></li></ul><ul><li><p><span><span>Tool to determine topographic features of the sump area including inflows, outflow, and extents.</span></span></p></li></ul><ul><li><p><span><span>Ensure that proposed elevations of entry points into redeveloped structures (ie. areaways, walk-in basements, window wells) are adequately protected or situated away from the sumps if part of the redeveloped property is in a sump.</span></span></p></li></ul><p><span>Contact: Land Development Services</span></p><p><span><span>Data Accessibility: Publicly Available</span></span></p><p><span><span>Update Frequency: As Needed</span></span></p><p><span><span>Last Revision Date: </span></span><span><span>12/15/2020</span></span></p><p><span><span>Creation Date: </span></span><span><span>12/15/2020</span></span></p><p><span><span>Layer Name: LDSAMGR.POTENTIAL_SUMP_CONDITIONS</span></span></p><p><span /></p></div></div></div>
