26.710.010 General purpose.
In order to ensure that all development is consistent with the goals and objectives of the
Aspen Area Community Plan and this Title, it is necessary and proper to establish a series of zone
districts to ensure that each permitted and conditional use is compatible with surrounding land uses, is
served by adequate public facilities, and is consistent with the environmental sensitivity of the City
and its surrounding area's natural resources. All development within each zone district shall be
consistent with the purposes stated for that zone district in this Chapter. Any use which is not
specifically listed in this Chapter as a permitted or conditional use in a zone district shall be
considered prohibited, unless otherwise interpreted by the Community Development Director
pursuant to Chapter 26.306.
26.710.020 Zone districts established.
The City of Aspen is hereby divided in several zones, known and designated as detailed in this
Chapter, to serve the purposes stated above and in each Section of this Chapter describing the
individual zone districts.
26.710.022 Zoning of lands containing more than one underlying zone district.
Whenever any parcel of land shall contain more than one underlying zone district, the
following rules shall apply:
A. Proposed use not allowed in all zone districts. When a parcel of land contains more than
one underlying zone district and the proposed use is not allowed in all of the respective
zone districts, then:
1. The use can only be developed on land in which it is a permitted or a conditional use.
2. The external floor area and density which shall apply to the use shall be calculated based
only on the land area of the zone district in which the use is a permitted or conditional
use. The off-street parking requirements and other dimensional requirements which
shall apply to the use shall be those of the zone district in which the use is a permitted or
conditional use, but shall be calculated on the basis of the land area and development of
the entire parcel.
B. Proposed use allowed in all zone districts. When a parcel of land contains more than one
underlying zone district and the proposed use is allowed in all of the respective zone
districts, then:
1. The use shall be developed by comparing each dimensional and parking requirement of
the respective zone districts and applying the more restrictive of each requirement.
These requirements shall, however, be calculated based on the land area and
development of the entire parcel.
2. The only exception shall be when the area of the parcel which is designated with the
zone district which permits the higher density constitutes more than seventy-five (75)
percent of the entire land area of the parcel. In this case, the use shall be. developed
City of Aspen Land Use Code Page - 301 Revised 01/01/99
Part 700 — Zoning Districts
Section 26.710.020
using the dimensional requirements and off-street parking requirements of the zone district
permitting the higher density, which shall be calculated on the basis of the land area and
development of the entire parcel.
26.710.024 Zoning of vacated areas.
Whenever any street, alley or other public way within the City of Aspen is vacated by the City
Council, the land on which the street, alley, or public way is located shall become a part of the zone
district of the lands adjoining such street, alley or public way. Those lands shall then become subject
to the regulations that apply to that zone district. In determining land available for development,
however, vacated lands shall be excluded from the calculation of allowable floor area, density or
required open space.
26.710.030 Official zone district map.
A. Establishment of zone district map. The location and boundaries of the zone districts
established in this Title shall be set forth on the Official Zone District Map of the City of
Aspen which is incorporated herein by reference into this Title as if fully described and set
forth herein. A copy of the official zone district map shall be located in the office of the
Community Development Department at all times for inspection by the general public
during regular business hours. The official zone district map shall be the final authority as
to the current zoning of land in the City of Aspen.
B. Amendment to zone district map. If pursuant to the terms of this Title, amendments are
made to the boundaries of the official zone district map, such amendments shall be entered
on the official zone district map promptly after amendment.
