DOT 3 d 1985 Boa 62 wH 570 <br />BARRIER ISLAND TRANSPORTATION IMPACT STUDY <br />Mike Brown, Senior Planner, reviewed the following Executive <br />Summary dated September, 1985: <br />INDIAN RIVER COUNTY <br />BARRIER ISLAND TRANSPORTATION IMPACT STUDY <br />ENECUTIVE SUMMARY <br />I. Introduction - The study analyzes the existing year, 2005, and "Built - <br />out" development conditions of the Orchid Island to determine trans- <br />portation roadway needs. <br />II. Existing Conditions and Trends - Key points that the study identifies <br />include: <br />a. Population growth on the island is projected as follows: <br />1980 2005 Built Out <br />6753 17,943 51,186 <br />b. Economy - Relative low level of employment, especially in North <br />and south sections, can be attributed to the lack of major <br />commercial and retail facilities or. the island. This condition <br />creates a situation in which most residents travel to the main- <br />land for retail shopping needs. <br />C. Land Use - 4,266 acres developed <br />6,873 acres vacant <br />In the past, development has occurred in the proximity of the <br />bridges. <br />d. Neighboring Counties - St. Lucie and Brevard County are presently <br />Producing and attracting 3200 and 2700 trips per day across the <br />County line, respectively. A percentage of these intercounty <br />trips need to be considered on the County's three bridges. <br />III. Future Growth and Developnent <br />Population Growth <br />Projected growth in each sub -area for the Year 2005 and Built -Out <br />Conditions show that the North Beach, Indian River Shores, and South <br />Beach areas have the greatest potential for growth. <br />Impact frM Adjacent Counties <br />Brevard County to the North has taken a conservative growth approach <br />and as a result of that philosophy,.the two way daily traffic at the <br />Brevard and Indian River County line will grow from the existing 2,700 <br />cars a day to 7,500 by the year 2000. <br />Growth in St. Lucie County, however, will create a significant impact <br />on Indian River County's Transportation network. Two way traffic at <br />the St. Lucie and Indian River County line will grow from the existing <br />3,200 vehicles per day to 23,200 vehicles per day. The St. Lucie <br />County Transportation Plan shows A -1-A being expanded to five lanes <br />and the north bridge being expanded to four lanes. No new bridges are <br />shown between the Indian River/St. Lucie Count' line and the existing <br />North Bridge in St. Lucie County. <br />2 <br />
