| Abstract: Represents Intensely Developed Areas, established by the Chesapeake Bay Preservation Act. | |||
| Purpose: Intensely Developed Areas contains linear feature types which are only used for GIS mapping. | |||
| Supplemental Information: Definition: The Intensely Developed Area (IDA) is a designated redevelopment area of the city which incorporates portions of the RPA and RMA. The IDA as displayed on the IDA Map includes areas in which development was concentrated as of 2004, so that little of the natural environment remains, and where at least one of the three conditions as described in Section 26-516.E of the Chesapeake City Code existed as of that date. 2004 Update: (adopted by City Council on 12/13/04: Ordinance 2004-331-321.) In the 2004 update of the Chesapeake Bay Areas additional streams, National Wetlands Inventory data, and soils information were used to delineate the limits of the City's RPA and RMA in accordance with the criteria specified in the Chesapeake Bay Preservation Act. The Commonwealth of Virginia adopted new regulations in 2000 and this update brings our maps into compliance with the new regulations. RPA Additional streams were included that could be 1) identified in USGS quadrangles, 2) interpreted into the GIS from existing orthophotos, and 3) observed from field investigation. These streams were digitized and conformed to the GIS contours, which were derived from the City's digital terrain model. Using the buffering criteria of 100 feet for RPA these additional streams were buffered. Additionally, any of the non-tidal wetlands connected by surface flow or tributary (perennial) streams identified from the National Wetlands Inventory layer, were also buffered by 100 feet and added to the RPA polygons. RMA The RMA was updated by buffering 1) these newly added perennial streams, 2) wetlands not included in the RPA, and 3) contributing upstream intermittent creeks that could be confirmed by at least two different sources (as the rule of thumb), by 500 ft. The RMA areas also include the limits of any soil polygons that were identified as "highly erodable," "steep slopes," or "highly permeable" soils and which intersected the edge of any RPA features. IDA Intensely Developed Areas are a subset of the RPA. They include areas of RPA that have no natural vegetation and have been served by sewer and water priort to 1991. 2007-2008 Update: The City’s Chesapeake Bay Areas were adopted by City Council on 12-13-04. They were amended by Ordinance # 2007-278-233. This ordinance was introduced on 10-08-07 and was unanimously adopted on 10-22-07. The purpose of this ordinance was to remove part of the property at 6903 Midlothian Turnpike from the Resource Protection Area. From the map titled “Gresham Woods RPA” that was attached to the ordinance, the upper extent of the RPA is approximately where the power line cuts through the property. The existing RPA was cut along the power line, as shown in the 2002 aerial photos. As part of the research done by the Timmons Group to determine the extent of the RPA, a new wetland that intersects the existing RMA was discovered on the property. This new wetland was digitized after a drawing showing the wetland was georeferenced to the parcel layer. A 100 foot buffer was created around the wetlands and merged with the edited RPA to create the new RPA. A 500 foot buffer was created around the new RPA to create the new RMA.
