The text of the ordinance indicates that there will be a public hearing before the City Planning Commission on July 6 on Ordinance 2009-135 (PDF), the official act of rezoning Union Hill that has been in the works for so long (though it is not on the published agenda for that meeting…).
The text also says that there will be a public hearing before City Council on July 27 at 6PM.
The move to set the zoning in Union Hill as R-63 was explained by UHCA President Matt Conrad in April:
… the Union Hill Civic Association unanimously endorsed R-63 for the entire interior of the neighborhood because we believe it is the best means of reestablishing a walkable, sustainable community with access to housing for persons at every stage of life, as well as access to goods and services.
R-63 is primarily a residential zoning tool that allows for single family and row houses. R-63 also permits multi-family housing on any lot larger than 4,000 square feet at a rate of 1 unit per 1,000 square feet of the underlying parcel. It has a maximum set back of 15 feet and a minimum height requirement of 24 feet. Fenestration must be toward the street. Commercial uses are permitted by right in 2,500 square feet of the first floor of each corner lot. The commercial activity is limited to neighborhood uses such as restaurants, art galleries, dry cleaners, etc. and there are NO parking requirements.
