How is Lewiston zoned?
Lewiston regulates land through 17 zoning districts, and the largest is Rural Agricultural at roughly 7,531 acres, more than twice the next largest classification. That marks how much of the city remains undeveloped.
The Neighborhood Conservation districts, lettered A and B and covering roughly 3,158 acres between them, are the primary framework for established residential areas. Naming them conservation rather than by density states an intent to maintain rather than to intensify, and the A district alone is the third largest classification in the city.
Three districts address the city's industrial heritage and centre. The Mill District at roughly 105 acres covers the historic textile mill complex, an explicit classification for buildings that would otherwise sit awkwardly in a general industrial or commercial district. Center Ville covers roughly 160 acres and a River Front district about 61.
An Urban Enterprise district covers roughly 623 acres, and a Downtown Residential district about 161, together providing the framework for the older core.
The conventional residential ladder runs low density at roughly 3,037 acres, suburban at about 1,312 and medium density at roughly 826. A Resource Conservation district covers about 1,109 acres. Business runs neighborhood, community and highway, with highway business the fourth largest classification at roughly 1,912 acres.
