SR - Suburban Residential — The SR Suburban Residential District encompasses an area primarily characterized as low-density single-family residential units with an average density of about one dwelling unit per acre. Also located here is one townhouse development with approximately four units per acre. Slightly more than one-third of the district is undeveloped land. The standards and development options applicable in this zoning district aim to make more efficient use of the Town's land resources and increase the supply of affordable housing by enabling its character to transition over time to that of the Urban Fringe and General Urban Transects discussed in the Comprehensive Plan. Base zoning standards protect existing neighborhoods from incompatible development and add two-family residential and accessory dwelling units by right. At the same time, development options provide an opportunity for context-appropriate infill and redevelopment of vacant and underutilized land and mixed-use development in planned communities. Along with residential development, the district also provides for siting public buildings, schools, churches, open spaces, public recreational facilities, accessory uses, and the like that are necessary or usually compatible with residential surroundings.

TR - Town Scale Residential — The TR Town Residential District encompasses an area primarily characterized as low to medium-density single-family residential units with an average density of slightly less than three dwelling units per acre. Approximately one-quarter of the district is unimproved, with parcels ranging from less than one-tenth of an acre to more than twenty-three acres. Consistent with the objectives of the Comprehensive Plan to make more efficient use of the Town's land resources and increase the supply of affordable housing, the district standards enable the district's character to transition over time to that of the General Urban and Urban Core Transects discussed in the Comprehensive Plan. Base zoning standards protect existing neighborhoods from incompatible development and add two-family residential and accessory dwelling units as a by-right use. At the same time, development options provide an opportunity for context-appropriate infill and redevelopment with missing middle housing unit types, accessory dwelling units, and mixed-use development in planned communities on larger parcels. District standards also provide for public buildings, schools, churches, open spaces, public recreational facilities, accessory uses, and the like that are necessary or usually compatible with residential surroundings.

MR - Mixed Residential — The objective of the MR Mixed Residential District is to facilitate the development of higher-density single-family and multiple-family residences within the Town core. Approximately half of the MR Mixed Residential District is comprised of improved properties featuring medium-density single-family homes, as well as higher-density townhouses and apartment units. This zone also encompasses certain commercial and mixed-use developments.

The objective for portions of the MR District that are adjacent to the Urban Core Transect and within a reasonable walking distance from the Town center is to promote the ongoing development of a diverse mix of higher-density residential options along with some commercial and mixed uses, like those found in the Urban Core Transect. In areas of the MR district that are more distant from the Town center, zoning regulations are implemented to safeguard existing neighborhoods from incompatible developments while permitting a variety of housing types in well-planned developments on larger parcels.

In addition, flexible development options allow context-appropriate infill and redevelopment projects within existing neighborhoods that enable the area to evolve to the adjacent urban center level of intensity but with discretion to ensure no neighborhood is overwhelmed by inappropriate development. The district standards also accommodate public buildings, schools, churches, open spaces, public recreational facilities, accessory uses, and other amenities that are essential or typically compatible with residential environments.

UR - Urban Residential — The UR Urban Residential District provides a framework for revitalizing underutilized areas east of MD 404, creating walkable, mixed-use communities that offer a range of housing choices and contribute to a more sustainable and vibrant urban fabric. The purpose of the MR-2 Mixed Residential District is to enable more compact, mixed-use nodes and encourage compact, sustainable, and vibrant urban form. The district is strategically applied to areas east of MD 404 currently characterized by scattered suburban development and vacant or underutilized parcels. By facilitating a range of housing types and densities, the district encourages a shift away from the typical low-density, single-family home-dominated suburban pattern, reducing sprawl and promoting more efficient land use.

The district allows a mix of single-family, multifamily, and townhomes to accommodate diverse needs and increase housing availability in vibrant, mixed residential neighborhoods that cater to a wider range of needs and demographics, attracting a more diverse population and a greater range of housing affordability. The district specifically permits the development of four-story townhomes as an innovative solution for increasing density while maintaining a compact footprint and providing functional living spaces. Permitting taller buildings is a key strategy for increasing density and making efficient use of land without significantly expanding a building's footprint. Allowing tall buildings promotes a more vertical development pattern, a hallmark of compact urban form.

District standards incorporate provisions to ensure new development complements the surrounding character, avoids abrupt transitions, and is compatible with adjacent land uses while allowing for a variety of housing types. The district's emphasis on compatibility with existing neighborhoods is crucial for successful integration in suburban areas.

GC - General Commercial — The purpose of the GC General Commercial District is to provide sufficient space in appropriate locations for a wide variety of business, commercial, and service activity, but which uses are not characterized by extensive warehousing, frequent heavy trucking activity, open storage of material, or the nuisance factors of dust, odor, and noise associated with manufacturing.

Commercial development in this district shall be in the form of well-planned commercial concentrations. Commercial development in this district shall be subject to standards for buffering and landscaping, access control, internal auto and pedestrian orientation, screening of loading/unloading and service areas, lot depth-to-width ratios which promote minimal road frontage, service roads, and reverse lot frontage concepts and other site design amenities which enhance aesthetic appeal.

I - Industrial - The purpose of the I Industrial District is to provide areas in the appropriate locations for light manufacturing, fabricating, warehousing, and wholesale distribution in low buildings with off-street loading and off-street parking for employees and with access to major thoroughfares or railroads. Development standards for this district shall control excessive heat, odor, noise, dust, and vibration nuisance impacts that could potentially occur. Extensive bufferyards and screening shall be required to screen industrial development from adjacent residential development. Waste removal businesses and similar uses are not permitted in this district. This primary zoning district further intends to allow the establishment of an adult-oriented business consistent with applicable laws or regulations.

MI - Mixed Industrial - The purpose of the MI Mixed Industrial District is to offer property located northeast of Lincoln Street and Gay Street and southwest of the old railroad spur the opportunity to transition over time, as directed by the market, to a more mixed residential use.
