the Miller Avenue corridor. While currently the area is mainly one-story commercial
buildings, this area provides for both neighborhood serving commercial uses on the ground
floors of buildings and mixed use with residential above (17 DU/acre to 29 DU/acre). New
development should meet the street and have a "main street" feel, with an emphasis on the
pedestrian environment. Buildings should be close-knit with two-story buildings
encouraged.

lot General Commercial (C-G) and Neighborhood (C-N) parcels at the transition from the
Miller Avenue "Main Street" down to the Miller Avenue "Marsh." This section will
continue its current development pattern and accommodate housing types with a density
