H. The modification of street requirements for <br /> affordable housing. <br /> As adopted, the county's existing sidewalk and street requirements provide for minimum <br /> construction standards to ensure public safety. According to section 913.09(b)(1) <br /> (Subdivisions and Plats) of the LDRs, all subdivisions must comply with the minimum <br /> standards set forth in Chapter 952 (Traffic). While Chapter 952 sets the minimum right- <br /> of-way width for a local or residential street at 60 feet, the minimum right-of-way width <br /> may be reduced to 50 feet if the street is constructed with a curb and gutter drainage <br /> system. In both cases, however, minimum lane widths remain the same at 11 feet. <br /> Although there is a higher cost associated with curb and gutter construction than with <br /> swale drainage, the reduction in the amount of right-of-way can produce a higher yield <br /> for a project. These street right-of-way requirements can be modified through the <br /> Planned Development(PD) process. <br /> Following is the county's current minimum right-of-way requirement. <br /> 913.09(6)(1) <br /> Minimum street and rights-of-way widths. The minimum street and rights-of-way widths shall be as <br /> stated in Chapter 952, Traffic, of the LDRs. The board of county commissioners may require the <br /> increase of right-of-way and pavement widths if it finds that the modification in width is consistent with <br /> the projected traffic needs and good engineering practice. No variance will be granted on minimum <br /> right-of-way widths for public streets. Right-of-way widths for one-way streets may be reduced from the <br /> above standards as approved by the public works director. <br /> ANALYSIS: <br /> As structured, the county's minimum street right-of-way width requirements are based on <br /> the minimum area needed to accommodate the various improvements that must be <br /> located in the right-of-way. Besides travel lanes, sidewalks, and drainage facilities, these <br /> improvements include water and sewer lines, gas lines, phone lines, cable lines, and <br /> others. Since the referenced improvements must be provided for in the road right-of- <br /> way, the county has determined that the minimum right of way width generally must be <br /> 60 feet for swale drainage roads and 50 feet for curb and gutter roadways. Reductions in <br /> those widths, however, may be accommodated via special designs approved through the <br /> County's PD (Planned Development) process. <br /> Because the county's minimum local road right-of-way width requirement may be <br /> modified through a PD process, when warranted, the county accommodates the subject <br /> incentive. <br /> RECOMMENDATION: <br /> The county's current street right-of-way general requirements are appropriate to ensure <br /> public safety, and the County's current allowance for modifications through the PD <br /> approval process should be maintained. <br /> F:\Community Development\SHIP\AHAC-Affordable Housing Advisory Committee(AHAC)\AHAC 2017\AHAC 2017 19 <br /> report.doc <br />
