26.435.040 Stream Margin Review.
A. Applicability. The provisions of the Stream Margin Review shall apply to all
development within one hundred (100) feet, measured horizontally, from the high water
line of the Roaring Fork River and its tributary streams, and to all development within the
100-year flood plain.
B. Exemptions. The Community Development Director may exempt the following
types of development within the Stream Margin Review area:
1. Construction of pedestrian or automobile bridges, public trails, or
structures for irrigation, drainage, flood control or water diversion, bank
stabilization, provided plans and specifications are submitted to the City
Engineer demonstrating that the structure is engineered to prevent
blockage of drainage channels during peak flows and the Community
Development Director determines the proposed structure complies, to the
extent practical, with the Stream Margin Review Standards.
2. Construction of improvements essential for public health and safety which
cannot be reasonably accommodated outside of the "no development area"
prescribed by this Section including, but not limited to, potable water
systems, sanitary sewer, utilities, and fire suppression systems provided
the Community Development Director determines the development
complies, to the extent practical, with the Stream Margin Review
Standards.
3. The expansion, remodeling, or reconstruction of an existing development
provided the following standards are met:
a. The development does not add more than ten (10) percent to the
floor area of the existing structure or increase the amount of
building area exempt from floor area calculations by more than
twenty-five (25) percent. All stream margin exemptions are
cumulative. Once a development reaches these totals, a Stream

Page 3 of 8
Margin Review by the Community Development Director or
Planning and Zoning Commission is reqttired; and,
b. The development does not require the removal of any tree for
which a permit would be required pursuant to Chapter 13.20 of the
Municipal Code.
c. The development is located such that no portion of the expansion,
remodeling or reconstruction will be any closer to the high water
line than is the existing development;
i. The development does not fall outside of an approved
building envelope if one has been designated through a
prior review; and
ii. The expansion, remodeling or reconstruction will cause no
increase to the amount of ground coverage of structures
within the 100 year flood plain.
C. Stream Margin Review Standards. No development shall be permitted within the
Stream Margin of the Roaring Fork River unless the Community Development Director
makes a determination that the proposed development complies with all requirements set
forth below. No Development shall be permitted within the Stream Margin of the
tributaries of the Roaring Fork River unless the Planning and Zoning Commission make a
determination that the proposed development complies with all requirements set forth
below.
1. It can be demonstrated that any proposed development which is in the Special
Flood Hazard Area will not increase the base flood elevation on the parcel
proposed for development. This shall be demonstrated by an engineering
study prepared by a professional engineer registered to practice in the State of
Colorado which shows that the base flood elevation will not be raised,
including, but not limited to, proposing mitigation techniques on or off-site
which compensate for any base flood elevation increase caused by the
development; and
2. The recommendations of the Aspen Area Community Plan:
Parks/Recreation/Open Space/Trails Plan and the Roaring Fork River
Crreenway Plan are implemented in the proposed plan for development, to the
greatest extent practicable. Areas of historic public use or access shall be
dedicated via a recorded easement for public use. A fisherman's easement
granting public fishing access within the high water boundaries of the river
course shall be granted to the greatest extent possible via a recorded
"Fisherman's Easement;" and,
Ordinance No.45, Series of 2001

3. There is no vegetation removed or damaged or slope grade changes (cut or
fill) made outside of a specifically defined building envelope. A building
envelope shall be designated by this review and said envelope shall be
recorded on a plat pursuant to Section 26.435.040(F)(1).
4. The proposed development does not pollute or interfere with the natural
changes of the river, stream or other tributary, including erosion and/or
sedimentation during construction. Increased on-site drainage shall be
accommodated within the parcel to prevent entry into the river or onto its
banks. Pools or hot tubs cannot be drained outside of the designated building
envelope; and
5. Written notice is given to the Colorado Water Conservation Board prior to any
alteration or relocation of a water course, and a copy of said notice is
submitted to the Federal Emergency Management Agency; and
6. A guarantee is provided in the event a water course is altered or relocated, that
applies to the developer and his heirs, successors and assigns that ensures that
the flood carrying capacity on the parcel is not diminished; and
7. Copies are provided of all necessary federal and state permits relating to work
within the one-hundred-year floodplain; and
8. There is no development other than approved native vegetation planting
within fifteen (15) feet back of the top of slope or the high waterline,
whichever is most restrictive. This is an effort to protect the existing riparian
vegetation and bank stability. New plantings (including trees, shrubs, flowers,
and grasses) outside of the designated building envelope on the river side shall
be native riparian vegetation as approved by the City. A landscape plan will
be submitted with all development applications. The top of slope and 100
year flood plain elevation of the Roaring Fork River shall be determined by
the Stream Margin Map located in the Community Development Department
and filed at the City Engineering Department.
9. All development outside the fifteen (15) foot setback from the top of slope
does not exceed a height delineated by a line drown at a forty-five (45) degree
angle from ground level at the top of slope. Height shall be measured and
determined by the Community Development Director using the definition for
height set forth at Section 26.04.100 and method of calculating height set forth
at Section 26.575.020, as shown in Figure "A'.
