e . e Reference Tables Used to Calculate Growth Projections * parks based on national standards for parks Growth Projections Both growth scenarios meet or exceed regional growth projections for the subregion. Reference tables were prepared for calculating growth pro- jections for each scenario (see above). Although densities for each devel- opment type remained constant between the two scenarios, there were dif- ferent formulae used for calculating net acreage-the Coalition growth sce- nario set aside more land for civic uses, parks, and open space. Calculating growth projections involved many detailed tasks, which, for purposes of this report, have been summarized into four steps. Step 1. Determine Net Buildable Acres Calculations began with estimating the number of buildable acres that exist in each (re)development area. GIS data bases, developed during the first study year, were the main information source for this calcula- tion. They were used to remove protected wetlands and slopes of 20 percent or more from the gross parcel acreage. Also, recent develop- ment projects on certain soil conditions in Blaine suggest that at least 30 percent of the site becomes open water because fill is needed to cre- ate building pads. In areas where similar soil conditions prevail 30% of the parcel was removed as unbuildable. Finally, 10 percent of all rede- velopment parcels was removed for storm water management pur- poses. 9
