Reserved strips controlling the access of public ways or which will not prove taxable for special improvements will not be approved unless such strips are necessary for the protection of the public welfare or of substantial property rights of the subdivider or both, and in no case except in which the control and disposal of the land comprising such strips is placed under a holding agreement or trust with a title company under terms and conditions approved by the Planning Commission. Such reserve strips will be approved where the City or other governing body requires a subdivider to make improvements that benefit an adjoining land owner and the City or other governing body may make arrangements for the adjoining land owner to pay a pro rata share of such improvement costs when the adjoining lands are subdivided, and the City or other governing body shall reimburse the original subdivider for their pro rata share of said costs or on the basis of some other program previously agreed upon.
