To help avoid urban sprawl and reduce automobile use, Nassau created and adopted the East Nassau Community Planning Area (ENCPA) for future land use. The county has certain goals for development within the ENCPA, including: facilitating multi-modal transportation and creating communities that discourage urban sprawl. The goals of development within the ENCPA directly promote public health through encouraging walking and biking, making sure they are safe by planning for them to exist in the future, and decreasing the amount of pollution created by vehicles.
