However, due to the nature of the zoning data
utilized, 10% of the population was not assessed due to mixed
zoning classes that contained residences. More zoning data
would improve this.Further,the building size three should developed
for this study (70 square meters (750 square feet)) is Stillwater
and may need to be in creased or decreased depending on
the building characteristics of other cities. In terms of spatial dis-
tri bution, some areas of the city, specifically near the periphery
(west, southwest, and northeast), were identified as being less
likely tohear the sirens. These areas would be the best candidates
for new siren installations. Over the previous few years the city has
made consistent efforts to install new sirens in areas where pop-
ulation growth has occurred (especially in the southwest) and
likely planning is underway to continue to improve coverage in
these areas.
