Land cover classification Casco Bay watershed. Source: National Land
Cover Database. In a continuation of recent trends, the total area of forested and agricul-
tural lands in the watershed declined by 3.35 square miles from 2011 to
2016. The total area of developed lands expanded by 1.13 square miles.

successes & challenges

▶ Individual towns and cities have been successful in applying Smart Growth approaches to balance economic growth
and development with agricultural, forestry, open space, and other community values, but home-rule decision making
results in irregular regional growth and development patterns.

▶ Many land use planning and conservation tools such as comprehensive planning, open space planning, conservation
subdivision design, and wetland and shoreland zoning are available to guide local development while protecting
water quality and habitat. Casco Bay communities can choose where and how to direct growth through planning and
land use ordinances.

▶ Within the region, ample opportunities exist for redevelopment in growth areas and for allowing increased density
to accommodate development that does not expand impervious surfaces. However, regulations aimed at restoring
impaired water bodies may create disincentives for doing so.

▶ Many challenges such as urban sprawl and traffic congestion are regional in nature, but towns handle solutions quite
differently. Better support and funding for regional planning is greatly needed to provide technical assistance on a
regional level for issues related to transportation and open space planning.
