Special Review Standards
A Special Review from the stream margin review determination may be approved, approved
with conditions or denied based on conformance with the following review criteria:
1.An authorized survey from a Colorado professionally licensed surveyor shows a different
determination in regard to the Top of Slope and 100-year flood plain than the Stream Margin
Map located in the Community Development Department and filed in the City Engineering
Department.
Staff Finds this Criterion to be Met
2.The proposed development meets the Stream Margin review standard(s)
upon which the Community Development Director had based the finding of
denial.
Stream Margin Review Standards
There is no development other than approved native vegetation planting taking place below the
top of slope or within fifteen (15) feet 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
Staff Finds this Criterion to be Met
