a. Where the proposed subdivision is a re-subdivision or concerns an area presently having any or all required improvements as previously set out, and where such improvements meet the requirements of this Article and are in good condition as determined by the City Engineer or County Engineer no further provision need be made by the subdividers to duplicate such improvements. However, where such existing improvements do not meet said requirements, the subdivider shall provide for the repair, correction, or replacement of such improvements so that all final improvements will then meet said requirements.
b. Where the proposed subdivision is a re-subdivision or concerns an area presently abutting or containing any existing public street of less than the minimum required right-of-way width or roadway width, land shall be dedicated so as to provide a minimum street right-of-way width established by these regulations and/or Planning Commission policy, and the subdivider of such proposed subdivision shall provide an additional roadway pavement meeting the minimum standards set by these regulations and the City Engineer or the County Engineer, as applicable. The Engineer shall determine what adjustment to make where the aforesaid widenings merge with existing streets which are of smaller width at the boundary of such proposed subdivision. The Engineer may reduce the minimum roadway required by these regulations to match an existing roadway system if the extension of such roadway is already improved at each end of the roadway in the subdivision and the roadway in the subdivision to be reduced is two (2) blocks or less in length. The Engineer may also require lanes to be painted on such widened streets designating driving and parking areas. The foregoing provisions requiring the widening of pavement may be waived by the Planning Commission when the length of such pavement is less than one (1) block.
