WHEREAS, the Aspen City Council has reviewed and supports the proposed clarification;
and,
WHEREAS,the Aspen City Council finds that this Resolution furthers and is necessary for
the promotion of public health, safety, and welfare; and
NOW, THEREFORE BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF
ASPEN, COLORADO THAT:
Section 1: TIA Clarification Obiective
The objective of the proposed change to the Transportation Impact Analysis (TIA) Guidelines is to
clarify that projects that do not involve development of new lodge or residential units or new
commercial or essential public facility square footage are exempt from the TIA Guidelines as they
do not result in an increase of vehicle trips.
Section 2: The following sections of the TIA Guidelines (pages 8-9) are hereby amended as
follows:
Level of Study and Mitigation
Table 1 shall be used to determine the level of transportation impact study and mitigation required for the
proposed development. These thresholds are based on the City's Growth Management Quota System
(GMQS), and may be amended administratively over time to reflect applicable changes to GMQS. For
the purposes of this document, development is divided into three categories: Exempt Development, Minor,
Development, and Major Development.
• Exempt Development: All development currently exempt under Growth Management would be
exempt from any new transportation mitigation system. This includes adding 500 sq ft or less of

commercial space, adding a single residential unit, or adding 2 lodge units to a project. Projects
that do not involve development, for instance a lot split or lot merger, are exempt. Projects that
maintain or decrease the number or amount of development of units or square footage in a use
category are exempt. If a project falls under this category it is exempt from TIA requirements and
TDM and MMLOS mitigation. The project may proceed directly to land use review or building
permit as applicable.
• Minor Development All development exceeding the exempt thresholds above, and located
inside the roundabout, regardless of size, is considered minor development. In addition, any
development outside the roundabout (along Highway 82, or up Castle or Maroon Creek Roads),
is considered minor development if it meets the following thresholds under"Minor Development—
Outside the Roundabout" in Table 1. All minor developments are required to perform a Level
One TIA which includes mitigation using Aspen specific TDM and MMLOS mitigation tools.
• Maior Development refers to any significant development located outside the Roundabout (i.e.
along the Castle Creek, Maroon Creek, and Highway 82 corridors), and is required to perform a
Level Two TIA which includes Capacity Analysis and a Site Plan Review. .Additionally the
development will mitigate using Aspen specific TDM and MMLOS mitigation tools in addition to
mitigating its significant impacts.
If a project falls within multiple development categories, it will be subject to the highest requirement. For
instance, if a project located along Castle Creek Road proposed 100 lodge rooms, 8,000 sq ft of net
leasable space, and 10 residential units, the development would be required to meet the major
development requirements because the lodge and commercial components trigger that threshold. If a
project inside the roundabout decreased the amount of net leasable space by 500 sq ft, but increased the
number of lodging units by 10, the project is considered a minor development. Similarly, if a project
located inside the roundabout proposed 200 sq ft of new net leasable space, 2 new free market
residential units, and 3 new affordable housing units, the entire project would be reviewed under the
minor development requirements because the 5 new residential units trigger that threshold.
