CHAPTER 64 - SITE DESIGN POLICIES

64.230 DETERMINATION OF RIGHT-OF-WAY WIDTHS:

The requirements of Sections 64.231 and 64.232 are intended to provide flexibility in the determination of right-of-way widths through the use of a formula in which all required elements will be identified and their needs assessed, rather than specifying a certain width for each type of street. In certain instances where major impacts are anticipated on the existing transportation network, a Traffic Impact Study (TIS) will be required for the purpose of identifying what improvements will be needed in order to handle the expected traffic volumes.

64.231

Determining Right-of-Way Width: The minimum right-of-way width shall not be less than required in the Official Map and Thoroughfare Plan.  The formula in this section shall be used to identify additional right-of-way needs for public and private roadways and may, subject to the recommendation of the Planning Commission and approval of the Council, be used to reduce dedication requirements.  To determine the right-of-way width for any proposed street or alley the developer or subdivider shall complete the following equation:  W = M+T+A+S+B+F, where: 

W  =    Right-of-way width     


M  =     Median width (needed for left turn lanes, traffic separation, and future widening)  


T  =      Width of Through Lanes (depends on number of lanes needed and the width of each lane, given the design speed and character of traffic.)    


A  =     Width of Auxiliary Lanes (includes such items as parking lanes, bike lanes, additional width for bus stop bays, additional width for curb and gutter.) 


S  =     Sidewalk Width 


B  =     Boulevard Width (includes area for snow storage, street hardware, utilities, and boulevard trees)        


F  =       Future Needs (includes anticipated or planned widening, and frontage roads)      

For guidance in the general requirements expected for each street type, the subdivider or developer shall consult the Currently Held Valid Thoroughfare Plan. 

64.232

Exceptions Approved by Council: Where a proposed right-of-way differs substantially from the Official Map or Thoroughfare Plan,  the applicant shall submit, along with the permit application, the justification or reasons for the changes requested, which will be acted upon as a design modification (see Section 60.440 and particularly Section 60.424 subd. 1(A) by the City Council during the site planning or land subdivision review.
