l bureaus, planning agencies, and s variety of other sources. The general consensus of these sources was that any increase in the number of overhight l accommodations, campgrounds, seasonal dwellings, or use of tha beach f acilities between 1985 and 2030  ; would be very modest. This is due'primarily to the existing highly-saturated state of the summer taurism and vacation trade in the study area, along

To account for any expansion by existing facilities and/or constructidn of new f acilities that might occur during the planning period, a projection rate of 14 growth per year for the first 5 years, 0.54-l                                   growth per year for the next 15 years, and 0.254 1

growth per year for the final 30 years was used. Differant criteria were applied to the model regarding vehicle-occupancy rates and mobilization time for transients under the dif ferent scenarios. These occupancy rates ranged from 2.4 par, sons / vehicle for overnight ,accommodatioes to 4.0 1 D e v e loped from discussions with the Merrimack Valley Planning Commission, the New England Innkeepers Association, the Campground Owners
