Dear Mr. Van Neil:
At the request of Don Perrotti, I have reviewed the Florida DOT study entitled " Analysis of Anticipated Hutchinson Island Traffic Conditions" dated April 1982, for relevance to the licensee's evacuation time estimate study.
The Florida DOT study indicated that projected growth will adversely affect traffic access to the island. The impact of this growth will be noticeable delays on a regular basis.
As far as the impact of projected growth on the evacuation time estimate, it will be necessary to revise the evacuation time estimates when significant growth takes place. The current guidance of NUREG 0654 is to provide esti-mates based on current populations.
It should be noted that capacity as considered in the Florida 00T Study relates to providing a good level-of-service during the peak hour. The ADT
" capacities" shown on page 4 of the Florida DOT study are not really capa-cities, but 24-hour volumes associated with normal peak-hour volumes. During an evacuation, 24-hour " capacities" larger than those shown could easily be achieved.
In summary, the importance of the Florida DOT study is that projected growth will result in undesirable peak-hour traffic conditions. Although this growth will affect evacuation times (which will be adjusted periodically if required), the problem will be more significant on a day-to-day basis in the form of congestion.
If you have any questions, please let me know.
Sincerely,
{
