The residential districts of the City of Lockport are listed in the following table. When this chapter refers to residential zoning districts it is referring to one of the following:

Low Density Residential
LDR

MDR
Mixed Residential
MR
A. 
Low Density Residential (LDR). The purpose of the LDR District is to recognize and protect the lowest density neighborhoods within the City of Lockport. These properties are generally characterized by owner-occupied, single-family detached homes with large, unobstructed front yards situated on lots of at least 1/4 acre in size. Future investment within the LDR District should be consistent with the existing low density development pattern of these neighborhoods while also continuing pedestrian connectivity to the City's denser neighborhoods and urban center.
B. 
Medium Density Residential (MDR). The purpose of the MDR District is to preserve and enhance the City's traditional neighborhood blocks consisting of single- and two-family homes. The MDR District provides a natural transition from the City's central high-density neighborhoods to its low-density fringe developments. Each block maintains a relatively uniform character, with unobstructed front yards, garages located in the rear yard, and home entrances fronting the street with connections to public sidewalks. Investment in the MDR District should continue to preserve the historic settlement pattern of these neighborhoods while providing for a moderate increase in residential density.
C. 
Mixed Residential (MR). The purpose of the MR District is to identify and provide for the highest density and variation in residential living opportunities within the City. MR District neighborhoods located nearest to the City center include some of Lockport's oldest, most diverse housing stock, comprised of single-, two-, and multifamily dwellings. While the composition of dwelling types may vary, these neighborhoods exhibit similar characteristics to the traditional block development pattern of the MDR District. Mixed residential neighborhoods also include existing apartment complexes and properties where the development of or transition to a mix of residential densities may be desirable. Where considered, future development and/or redevelopment proposals shall achieve the following:
(1) 
Establish neighborhoods with a variety of housing options in a pedestrian-scale environment;
(2) 
Locate residential types and densities in a manner that provides a natural transition from existing single- and two-family neighborhoods to higher density developments, community resources, and commercial centers;
(3) 
Provide for the preservation and rehabilitation of historic structures and sites;
(4) 
Develop on- and off-site connections to nearby amenities, roadways, sidewalks, parks and trails; and
(5) 
Create a cohesive and interconnected traditional neighborhood development pattern throughout the entirety of the district area, regardless of the sequence of proposals or project phasing.
A.
