Dublin GIS database

Description:

Areas within the designated study bounds which have been confirmed as wetlands, or have the potential to be confirmed as wetlands and 100’ buffers around all wetland and potential wetland areas.

Intent:

To identify the areas throughout the study bounds which are, or have the potential of being wetlands and to add value to these areas for inclusion in the suitability model. In addition to the identification of wetland and potential wetland areas, the intent to protect these areas was forwarded by the creation of buffers around the wetland areas. These buffers are identified as a means of further protecting the wetland areas from possible development pressures and for increasing available habitat zones to be incorporporated into habitat corridors.

Analysis Summary:

The Wetlands summary was created to distinguish the areas within the study bounds which either are, or have the potential, to be wetland areas. The areas defined in this summary included hydric soils in the identification of potential wetland zones.

This process was started by examining the data made available from O.D.N.R. and comparing it with the data provided by Dublin. While there was overlap in the areas defined as wetlands, it was apparent that the data provided by the city of Dublin was created with a higher degree of precision than the data from O.D.N.R. For this reason, the wetland data layers were combined to create a wetland map containing wetlands defined by both O.D.N.R. and the City of Dublin.

After the wetland areas were defined by combining the data from Dublin and O.D.N.R., a 100’ buffer was added around each of the wetland zones. Relative to environmental importance, the areas defined as wetlands, or potential wetlands, were given the highest values. The associated buffers allowed for a transition of high values on the wetland side to lower values as the distance from the wetland area increased.
