South County Integrated Mobility Study

2.3.3 Additional Analysis: Environmental Constraints Developable and re-developable parcels were further evaluated in terms of the presence environmental constraints. Parcels with 75 percent or more land area covered by water, wetlands, and FEMA regulatory floodways were withdrawn from consideration. This process resulted in the removal of 1,624 parcels (6,640 acres) from consideration as developable and 588 parcels (3,785 acres) from consideration as re-developable sites (Table 12). Parcels with less than 75 percent of land area constrained by water, wetland, and flood hazard areas were labeled partially constrained. Unconstrained acreage for partially constrained parcels was then calculated and added to the total acreage of developable and re-developable parcels. The total number of parcels, total acreage, and unconstrained acreage for the developable and re-developable parcels are provided in Table 12. A total of 10,396 parcels (31,364 acres) were identified as having development and redevelopment potential, but only 8,184 of those parcels (20,939 acres) were determined to be unconstrained (including partially and unconstrained sites). Next, the parcels with development and redevelopment potential were sorted by the size of unconstrained acreage to identify clusters of small parcels that could be assembled for development. Most of the unconstrained parcels (7,462 parcels) with development and redevelopment potential are less than five (5) acres. A total of 722 sites greater than five (5) acres were considered as developable or re-developable, with 152 of these parcels having more than 20 acres. Figure 27 identifies the sites with development and redevelopment potential, as well as public land and environment constraints. Table 12.
