1 This is the minimum front required for a lot abutting a local street. Where a front or side yard of a lot abuts a major thoroughfare or frontage road to a major thoroughfare, based on the Thoroughfare Plan, an additional 10 feet shall be required for the adjacent front and side yard. This requirement does not apply to nonresidential land uses. In the R-1 and R-2 districts, where existing dwellings have a front yard of more than 20 feet, all new development shall be required to have a minimum front yard that is equal to or greater than the front yards of abutting lots that have front yards abutting the same street. 2 In the R-2 and R-3 districts, where all dwellings located along the side street have a front yard less than the required 20 feet, the side street side yard shall be permitted to be reduced to the front yard but in no case shall the side street side yard be less than 10 feet. 3 Any building in the R-1 district greater than 30 feet in height shall be set back from all lot lines 1 foot for each foot the building is greater than 30 feet. Any building in the R-2 or R-3 districts greater than 35 feet in height shall be set back from all lot lines 1 foot for each foot the building is greater than 35 feet. 4 All buffering and screening requirements as identified in § 152.085 Buffering and Screening shall be complied with under these provisions of this chapter. 5 The historic downtown area shall be determined as identified on the Byron Comprehensive Plan Neighborhood Districts Map. 6 The minimum rear yard may be reduced to zero where a commercial establishment has a part of its business located on an abutting lot which is located only within the commercial or industrial districts. 7 Where the use abuts a residential zoning district or a federal, state or county highway, a 45 foot setback shall be required. 8 Where an industrial establishment abuts a railroad right-of-way, the abutting side or rear yard may be reduced to zero. The minimum side or rear yard may be reduced to zero where an industrial establishment has a part of its business located on an abutting lot which is located only within the Commercial or Industrial District. 9 This percentage refers to 100% of the area available for building. This area is the area remaining after providing the minimum area or more for yard requirements, buffer and screen requirements, parking area and loading/unloading requirements where required.
