Development should be directed to those areas of shoreline accretion, and avoided in areas of shoreline erosion. I don't know how to convert the points to lines. Faulting is a major reason for land subsidence. Development should occur outside a 100 meter fault buffer to avoid subsidence hazards. There are no national parks and preserves in the galveston island.
Faults are too far away from it to be considered.
Preserves Merge these land use quads and get one land use grid file. Wetland, Storm Surge, GOM Erosion, Galveston Island, and Tiff images. The selection part is Upland which is buildable. This model deals with data mainly by additive overlay. This causes those areas with no data have low constraints value and therefore seem suitable for development.
