Groundwater levels are also provided to monitor local aquifers. Lastly, these stations will be used as PWD's long-term wet-weather monitoring stations, building upon the extensive period of flow and continuous water-chemistry records. In addition, the "color coding" (red, yellow, green) of various water-quality parameters will allow scientists at a glance to monitor the aquatic health of our riverine systems on a daily basis and provide a yearly aquatic health report card to PWD, state, federal, and local watershed groups/agencies. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in the City in support of watershed restoration initiatives occurring within the City. Gaging stations were placed at/near the county border and at the furthest downstream location with no tidal influence. Two gaging stations in each watershed were strategically positioned to monitor water quantity and quality entering and exiting the City's watersheds. This monitoring network is equipped with both water-quantity (water discharge and stage) and water-quality (pH, specific conductance, dissolved oxygen (DO), temperature, and in some cases, turbidity) measurement equipment that report data in near real time (within hours). The work entailed the creation of new streamgaging stations, resurrection of historical gaging stations and/or upgrades of existing gaging stations. Groundwater Monitoring Web App (Opens in new window) OOS will be letting residents in Eastwick know about these changes through letters in the mail and door-to-door outreach as part of ongoing efforts to improve communication and transparency between Eastwick residents and governmental partners.Water Quality W eb App (Opens in new window) The changes are expected to go into effect Summer 2023. If the cost for a project is 50,000 or more, you must attend a flood protection scoping meeting before. There are two primary flood hazard zones within a coastal SFHA. Properties within the SFHA are at a high risk of flooding, with at least a 26 chance of flooding over the course of a 30-year mortgage.
#PHILADELPHIA FLOOD MAP CODE#
Refer to the code bulletin for development in special flood hazard areas and L&I guide for development in the floodplain. Flood maps show the Special Flood Hazard Area (SFHA) the area that would be affected by a 1-annual-chance flood (or base flood).
Community in the next three years (2019-2021). You must submit flood protection documents with all zoning or building permit applications for construction in the SFHA. This information can help residents decide how high to elevate their utilities or more important items on the ground floor to prevent damage in a flood.įEMA has also developed an interactive story map to observe these new mapping changes. Task Force Strategic Plan outlines a strategy to position the City to become a CRS.
#PHILADELPHIA FLOOD MAP UPDATE#
The major update in this map is that more residents will have information about their “base flood elevation”, or the estimated depth of flooding in a 1% chance flood event. As one of the lowest lying neighborhoods in the city, Eastwick has been at the forefront of a variety of major flooding events over the years, including Hurricane Floyd in 1999, and more recently Tropical Storm Isais in 2020. Philadelphia, US Flood Map may help to provide flood alert/flood warning if flood water level at certain point is rising. FEMA has recently produced an updated floodplain map of the Eastwick section of Philadelphia. Philadelphia, US Flood Map may be useful to some extent for flood risk assessment or in flood management, flood control etc.
