The sign on the coefficient estimates for the distance to the
primary employer or Gate One of the Naval Air Station is
negative and not significantly different from zero. The signs
on the coefficient estimates for the distance to the county
landfill variables in both equations, were opposite of our initial
expectations. The county landfill, which is found in the
northeastern part of the watershed, is located along the
same road as one of the largest and most desirable planned
communities in this part of the county. Typically, living near a
landfill is deemed undesirable because of potential environmental
quality issues as well as truck traffic. However, this
study's regression results indicate that proximity to the landfill has an overall desirable effect. Median income was
significant in each model; however, the negative sign of its
coefficient was the opposite our expectations.
