As used in this title, the following land use designations shall be considered overlay districts:
(underlying zone)-PBD
(Parking and Buffer District)
(underlying zone)-RD
(Recreational District)
(underlying zone)-HPD
(Historical Preservation District)
(underlying zone)-RPDD
(Residential Planned Development District)
(underlying zone)-IPDD
(Industrial Planned Development District)
(underlying zone)-EBOD
(Electronic Billboard Overlay District)
(underlying zone)-CCOD
(Civic Center Overlay District)
(Ord. 806 § 1, 2007; Ord. 886 § 3, 2018; Ord. 929 § 9, 2023)
The overlay districts are intended to create an umbrella of additional standards over and above the existing underlying zones in order to meet the special needs of landmarks, distinct neighborhoods, and busy shopping centers and corridors within the city. The specific intent and purpose of each overlay district is identified below:
A. 
PBD (Parking and Buffer District). Established to designate areas that may be used for motor vehicle parking with open space in order to serve as a means of reducing conflicts between incompatible uses along zone boundaries and provide additional public parking and open space opportunities.
B. 
RD (Recreational District). Established to designate areas where public and private recreational facilities may be established, including but not limited to amusement parks, miniature golf courses, outdoor entertainment, and other facilities developed for leisure time activities. Provisions are included to permit incidental uses and necessary public and community services.
C. 
HPD (Historical Preservation District). Established to protect those existing elements in the environment which complement or are essential to the physical setting of a declared historical or cultural monument or site, and to ensure that adjacent public and private development is harmonious and consistent with the character, style and spirit of the monument or site.
D. 
RPDD (Residential Planned Development District). Established to provide a means of achieving greater flexibility in residential development on relatively large tracts of land by encouraging designs that are more self-sustaining with their own private streets, common space, recreational opportunities, and property maintenance. Among the objectives of planned development is the encouragement of more efficient use of open space, separation of pedestrian and vehicular traffic, where possible, and increased environmental amenities. Adequate safeguards to ensure that such projects will be an asset to the surrounding neighborhood area are provided through the requirement of a conditional use permit prior to development of a planned residential development in the zone.
E. 
IPDD (Industrial Planned Development District). Zone IPDD is established to provide a means of achieving unified industrial development in the proximity of other types of uses. Adequate safeguards to ensure that such projects will be an asset to the surrounding community are provided through the requirement of a conditional use permit prior to development of a planned industrial development in the zone.
F. 
EBOD (Electronic Billboard Overlay District). The EBOD is established to create an overlay district that provides for the development and construction of electronic billboards in a planned manner by allowing for the construction of electronic billboards within the EBOD and to allow the voluntary relocation and replacement of conforming and nonconforming billboards from other areas of the city to the EBOD subject to reasonable controls.
(Ord. 806 § 1, 2007; Ord. 886 § 4, 2018)
Land uses permitted within the overlay districts shall be based on the underlying districts. However, any use the director feels complements and meets the intent of the overlay district may be permitted subject to the approval of a conditional use permit.
(Ord. 806 § 1, 2007)
This section establishes the development standards of the overlay districts. These standards are in addition to the standards of the underlying zones as well as the supplemental development standards found in Division 4 of this title, which establishes development standards such as parking, landscaping, signs and other standards not prescribed within this chapter.
A. 
Parking and Buffer District Standards.
1. 
Parking Standards. Twenty-five percent additional parking shall be provided over and above the requirements of the underlying zone. In addition, all site vehicular entries/exits shall be treated with colored, stamped concrete or pavers to the satisfaction of the community development director. Said parking requirements shall only apply to new development or cumulative additions within a 10-year period greater than 50 percent of the existing building area.
2. 
Landscaping Standards. Ten percent additional landscaping shall be provided over and above the requirements of the underlying zone. Said landscaping shall be concentrated along the street frontages. Any addition greater than 50 percent of existing floor area shall be required to upgrade landscaping to meet the requirements of this district. Landscape and irrigation plans prepared by a licensed and certified landscape architect shall be submitted for all proposed landscaping.
B. 
Recreational District Standards.
1. 
Lot Standards. Minimum lot area required shall be 20,000 square feet. Minimum lot width and depth shall be 100 and 150 feet, respectively.
2. 
Parking Standards. Unless identified in Chapter 9.38 BGMC, Parking and Loading (Off-street) by land use, parking numbers shall be determined by the planning commission and shall be based on the results of a parking demand study prepared by an independent traffic engineer.
C. 
Historical Preservation District Standards.
1. 
Process for Modifications to Property.
a. 
Prior to obtaining a building permit to construct, repair, demolish, relocate, or modify in any way any structure, landscape feature, or overall physical setting of a property located in the historical preservation district overlay, site plan review approval shall be obtained from the cultural heritage commission and the planning commission.
b. 
Required plan submittals for approval shall include, but not be limited to:
i. 
Complete project description/scope of work.
