It is bounded by NW/SW 72nd Ave. (Milam Dairy Road) on the east, SW 8th St. (Tamiami Trail) on the south, the Homestead Extension of Florida's Turnpike (SR 821) on the west, and NW 74th St. on the north. This area of approximately 27 square miles has shown a rapid rate of low density growth since Hurricane Andrew struck southern Dade County in August of 1992. Many businesses that were once located in the southern portion ofthe County have decided to relocate to West Dade which is further inland from the coast line. The tremendous growth, especially in employment, has exacerbated the traffic congestion on the roadway network in the study area. Although there are three limited access highways that traverse the region, the internal grid network of arterials is incomplete and creates a funnel through which most traffic must travel. To add to the traffic woes, 24 new large developments have received vested rights to construct warehouses, offices, retail space, single family, and multi-family structures in the West Dade Area. The vestment allows these developments to bypass the level of service (LOS) standards required by the Dade County Comprehensive Development Master Plan (CDMP). These standards have been raised from LOS E to LO::,!) beginning in January 1, 1995. This means that many roadways in the study area, which were near the threshold of maximum acceptable capacity, are now considered to have unacceptable levels of congestion, even without the previously mentioned developments. It is also important to mention that many small developments and existing business expansions have already been approved for the West Dade area as well. These developments do not generate as many trips but the 133 different activities have at least some impact on the area's roadway network. Combined with the vested rights developments, there are expected to be more than 22,000 new PM peak hour trips generated over the next five years just from the approved sites. These trips would add to the existing 136,000 PM peak hour trips. (These numbers do not reflect the trips on the three expressways in the study area.) This analysis was structured to address only the needs of existing and other regulated or permitted new trips over the next five years. It is, of course, possible and likely that other new developments will be proposed and will make application for development approval. Such projects are not included in the analysis database for this project.
