Subsec. 10-4-3.2.F Neighborhood Conservation

Purpose. The purpose of this Subsection is to establish standards that enable new investment and reinvestment in existing neighborhoods without disrupting their character. The longest-standing neighborhoods in Littleton have been well-maintained and are regarded for their quality, integrity, and livability. These neighborhoods warrant standards to preserve their unique neighborhood characteristics and offer alternative opportunities to invest in existing neighborhoods other than through redevelopment.

Applicability.

1.
Generally. This Subsection applies to all neighborhoods with single-family detached dwelling units within the Corridor Mixed (CM), Medium Lot Residential (MLR) and Small Lot Residential (SLR) districts. Improvements that conform to the standards of this Subsection and are consistent and compatible with neighborhood character may be approved by the Director.
2.
Existing Dwelling Addition or Expansion. These standards may be applied if a proposed addition to or expansion of an existing dwelling meets the following:
1. a.
  Allows construction on adjoining lots to be built to the same standard along the same setback line;
2. b.
  Does not result in non-compliance with applicable building codes on the subject lot or on abutting lots;
3. c.
  Does not materially alter drainage conditions from those existing prior to building improvements; and
4. d.
  Does not encroach in an easement or public right-of-way.

Conforming Lots and Buildings. Refer to Section 10-10-1.1, Generally.

Existing Nonconformities. A large number of residential lots do not conform with the lot area standards of the former zoning districts. This Code reflects adjustments to the minimum required lot areas to mitigate the extent of nonconforming lots to the greatest extent practicable. The adjusted lot areas are set out in Table 10-4-2.2, NB Lot and Building Standards.

Alternative Standards.

1.
Approval Required. Modifications to buildings that include alternative standards shall submit building plans for review and approval by the Director.
2.

3.
Easements, Rights-of-Way, and Environmental Features. These alternative standards shall not be construed to authorize construction of buildings or portions of buildings, located in utility or drainage easements, public rights-of-way, or to encroach upon or cause unnecessary damage to or destruction of environmental resources (e.g., trees, steep slopes, wetlands, floodplains, rivers, streams or their riparian areas, and greenways).
4.
Alternative Front Setback.
1. a.
  Average Setback. As displayed in Figure 10-4-3.2.F, Front Setback Averaging, the front setback for a building addition or expansion proposed on the subject lot may be reduced to the average front setback along the same side of the same street in the same zoning district, provided that:
  1. 1.
    The accessway is at least 25 feet long if used to directly access the lot from a public right-of-way. The required length of the access is measured from the property line to a building wall or garage door; and
  2. 2.
    The setback of the subject lot proposed for addition or expansion is not counted in the calculation.
