A. Sidewalks. Public sidewalks shall be constructed along any and all of the property frontages adjacent to a public roadway. The design and location of the sidewalk shall be approved by the City as part of Public Improvement Plans or Site Plan, whichever is deemed applicable by the City Engineer, prior to installation. If deemed necessary, in conjunction with sidewalk improvement plans, a Stormwater Management Plan detailing and addressing the impacts of additional impervious surfacing shall be prepared at the developer's expense, by a professional engineer licensed in the state of Iowa. Any deviations in design or location from standard sidewalk improvements will require the approval of the City Council. All required sidewalks shall be installed within one (1) year of the adoption of this ordinance unless the City Council requires or approves an alternate time line.
B. Open Space. 19.4% (23,656 square feet) of the site shall be maintained as open space. Open Space shall be considered those areas unencumbered by structures, off-street parking, outdoor storage areas, and vehicle use drives, loading and other areas. A minimum of two (2) trees and three (3) shrubs shall be provided for every 3,000 sf of open space based on 20% of the site. Minimum vegetation requirements for one category or landscaping purpose are in addition to another (i.e. open space vegetation is in addition to vegetation implemented for screening of parking or outdoor storage).
C. Parking and Circulation Drives.
1. A minimum of five (5) patron parking spaces shall be provided within the site. If additional parking is determined to be needed by evidence of patron vehicles parking on grass areas or adjacent to storage units beyond the time necessary to load and unload, additional parking, up to a maximum of eighteen (18) stalls will be required to be implemented. A portion of the allowed outdoor storage areas will need to be converted to provide the additional parking so as to not further decrease the percentage of open space provided within the site. Said converted parking areas will need to comply with all of the provisions stated within this section, including being paved.
2. Off-street parking areas shall be setback a minimum of ten feet (10') from property boundaries.
3. Patron parking shall occur on paved surfaces only. No curbing shall be required along the perimeter of off-street parking areas.
4. Vehicle circulation pathways within the site shall be paved in accordance with City Code, except no curbing shall be required.
5. Views of patron parking areas from adjoining public roadways shall be screened to a height of three feet (3') through the use of topography, maximum three-foot (3') fencing or wall or vegetation of a coniferous variety.
6. Patron parking areas shall be marked in accordance with the Manual on Uniform Traffic Control Devices (MUTCD, Federal Highway Administration) standards.
7. Patron parking shall not be used for storage of vehicles or other items and materials.
8. To ensure the ability of emergency response vehicles to circulate within the site, patron vehicles shall not be parked adjacent to storage units longer than the time necessary to load or unload items to/from the storage unit.
D. Dumpster Enclosure. At such time that the existing dumpster enclosure warrants rebuilding due to deterioration of materials, the dumpster shall be relocated to the northwest corner or within the western outdoor storage area.
The dumpster enclosure will need to comply with current City Code regulations regarding materials and access.
E. Outdoor Storage. Outdoor storage areas shall not be expanded beyond what exist at the time of adoption of this ordinance. The outdoor storage of vehicles and materials shall be allowed along the western boundary of the site and the western 240 feet of the northern boundary under the following conditions:
1. An eight-foot (8') tall, opaque fence is erected adjacent to all outdoor storage areas at a minimum ten-foot (10') setback from all property boundaries.
2. No vehicles, including recreational vehicles or materials stored along the northern boundary shall be visible above the fence.
3. Views of the western storage area from the adjoining property to the south shall be mitigated through topography and/or implementation of vegetation. Any existing vegetation currently located along the southern boundary (indicated on the 2020 site plan on file with the City) removed that results in views of the western storage area shall be replaced with equal caliper inches of diameter at breast height (dbh) (i.e. a 4" tree removed shall be replaced with the equivalent of 4" of trees, that is, four 1" trees, two 2" trees, etc.).
4. Screening of views of the western outdoor storage area from the Grand Avenue frontage shall not be required.
5. Gravel surfacing shall be allowed when bounded by either a solid fence or a minimum six inch (6") wide curb to contain the gravel and prevent migration of the gravel material into grass areas. Said curb shall be comprised of a material capable of withstanding the weight of maintenance equipment without crumbling such as, wood, asphalt, concrete, or other suitable material approved by the City. Asphalt or concrete pavement shall be required when the above fence and curbing parameters are not provided.
6. No outdoor storage shall be allowed within drive aisles associated with the covered storage units or at the terminus ends of the buildings. (Ord. 2440, 9-21-2020)
