(A) It is found that increased vehicular traffic results from construction of new buildings and extensive reconstruction, remodeling and enlarging of existing buildings. The following street dedications and standard improvements are determined to be necessary to prevent vehicular congestion and the other hazards related to the intensified use of the land, and for the preservation of the public health, safety and general welfare.
(B) The following requirements shall be met or complied with before a building permit is issued for any complex or building or, in the alternative, before the complex or building is accepted for use and occupancy:
(1) All required streets, highways and alleys which abut the subject property shall be dedicated to the full width designated by the “Ultimate Street Right-of-Way Widths Map” or other official plans or standards adopted by the City Council.
(2) All street, highways and alley improve-ments shall have been installed and in good repair or street improvement plans shall be prepared to city standards and said improvements constructed. Such improvements shall consist of, but not necessarily be limited to, excavation, concrete curbs and gutters, concrete sidewalks, pavement, drainage facilities or any other engineering requirement.
(3) Whenever reconstruction, remodeling, enlarging or modifications to existing structures are involved, the street dedication and improvements described under this section shall be required at the time of issuance of a building permit when the value of such reconstruction, remodeling, enlarging or modification exceeds 50% of the market value of the existing structure. The market value as used in this section shall be that value as based on the official assessed valuation of the current County Assessor roll. In addition, whenever there has been a cumulative value of improvements made during the preceding five years, with or without the addition of proposed new construction, amounting to a value which exceeds 50% of the market value of the existing building structure or improvements, the required street dedication and improvements shall also be required.
