APPENDIX 4. The area of habitat expected to be impacted for each of the 18 projects in the Pleasant Grove study area.


This table shows the sometimes minute habitat areas that will be impacted by the programmed road construction in the Pleasant Grove study area. If the environmental review and mitigation obligation assessment, and the subsequent purchase of land for all these projects is done on a project-by-project basis, the whole process will take a considerable time, and each project’s environmental review will typically start near the end of that project’s lifecycle. Incorporation of regional planning offers the possibility of speeding the process through early assessment of projected habitat impacts and identification of associated mitigation needs; earlier acquisition of lands to fulfill mitigation obligations, which may be less expensive; and selection of mitigation sites that fit within a regional greenprint design.
