Screening and landscaping requirements in a P-1 Vehicular Parking District are as follows.
(1) The parking area shall be provided with a continuous and completely obscuring wood or masonry wall or fence 4 feet 6 inches in height measured from the surface of the parking area. This wall or fence shall be provided on all sides where the next zoning district is designated as a residential district except in the instance where such residential district is across a street such wall or fence may be provided as a landscaped screening planting area. Whenever such wall is required, all land between the wall and boundaries of the P-1 District shall be kept free from refuse and debris and shall be landscaped with deciduous shrubs, evergreen material and ornamental trees. Ornamental trees shall be planted at 30-foot intervals, 6 feet from the wall. The ground area shall be planted and kept in lawn. All such landscaping and planting shall be maintained in a healthy, growing condition, neat and orderly in appearance.
(2) All planting plans shall be in accordance with the provisions of subsection (1) of this section and in accordance with § 82-460.
(1993 Code, § 82-403) (Ord. passed 10-12-1992)
The entire parking area, including parking spaces and maneuvering lanes, required under this section, shall have portland cement or asphaltic concrete surfacing in accordance with specifications approved by the Director of Public Works or his designee. Such facilities shall be drained so as to dispose of all surface water accumulated in the parking area. The parking area shall be surfaced within 1 year of the date of rezoning for P-1 vehicular parking use if the parking area is to serve an existing use.
(1993 Code, § 82-404) (Ord. passed 10-12-1992)
(A) The Planning Commission, upon application by the property owner of the parking area, may modify the yard and wall requirements where, in unusual circumstances, no good purpose would be served by compliance with the requirements of this article.
(B) In all cases where a wall extends to an alley which is a means of ingress and egress to a parking area, it shall be permissible to end the wall not more than 10 feet from such alley line in order to permit a wider means of access to the parking area.
(C) In addition to the requirements in this article, such parking area shall comply with such further requirements or conditions as may be prescribed by the Planning Commission for the protection of the residential district abutting such parcel in which the parking area is to be located.
(1993 Code, § 82-406) (Ord. passed 10-12-1992)
(A) Intent.
(1) The intent of this section is to establish roadway access standards inclusive of driveways, shared drives, frontage and rear access and road related roadway geometric improvements and access control features.
(2) The compliance standards of this section are intended to minimize potentially hazardous traffic movements and related traffic conflicts, provide effective spacing standards between driveways and between driveways and intersections and to ensure reasonable access to properties within desired public safety standards. The provisions of this section shall apply during the site plan review process before Planning Commission approval.
(B) Driveway spacing.
(1) Definitions. For the purposes of this section, a COMMERCIAL DRIVEWAY is defined as any vehicular access, except those serving single family or two family residences or serving an essential public service structure.
(2) Minimum spacing (commercial). Minimum spacing between 2 commercial driveways on the same side of the roadway shall be determined based upon the posted speed limit along the parcel frontage. The minimum spacings indicated below are measured from centerline to centerline.
Posted Speed Limit (MPH)
|
Minimum Driveway Spacing (Feet)
|
25 | 130 |
30 | 185 |
35 | 245 |
40 | 300 |
45 | 350 |
50 | 455 |
(3) Left-turn conflicts. To reduce left turn conflicts, new commercial driveways shall be aligned with existing driveways across the roadway where possible. If alignment is not possible, driveways should be offset a minimum of 150 feet from existing driveways, measured centerline to centerline, on the opposite side of the roadway.
(4) Minimum spacing. Minimum spacing between proposed driveways and street intersections shall be subject to the following requirements. The following measurements are from the nearest edge of the driveway throat to the nearest edge of the intersection.
Location of Driveway | Minimum Spacing for Full Movement Driveway (Feet) | Minimum Spacing for a Channelized Right-Turn-In, Right-Turn-Out Driveway (Feet) |
On a major thoroughfare, intersecting street is a major thoroughfare | 250 | 125 |
On a major thoroughfare, intersecting street is not a major thoroughfare | 200 | 125 |
On a secondary thoroughfare | 125 | 75 |
On a collector street | 75 | 75 |
(5) Number of commercial driveways.
(a) The number of commercial driveways serving a property shall be the minimum number necessary to provide reasonable access and access for emergency vehicles, while preserving traffic operations and safety along the public roadway.
(b) Access shall be provided for each separately owned parcel. This access may be an individual driveway, shared driveway, or via a service drive. Additional driveways may be permitted for the property only as follows: 1 additional driveway may be allowed for properties with continuous frontage over 300 feet, and 1 additional driveway for each additional 300 feet of frontage, if the Planning Commission determines additional access is justified without compromising traffic operations along the public street. The applicant shall submit a traffic impact study if additional access is sought. All driveways shall comply with the spacing requirements set forth in this section.
(c) In making its determination on whether additional access is justified, the Planning Commission may refer to the following list of developments, that generate enough traffic to warrant consideration of additional access. Where possible, additional access points should be located on a side street, shared with adjacent uses, or designed for right-turn-in, right-turn-out only movements.
1. Multiple family developments with over 500 units.
2. Grocery store of over 30,000 square feet (GFA).
3. Shopping center with over 40,000 square feet (GFA).
4. Hotel or motel with over 400 rooms.
5. Industrial developments with over 300,000 square feet (GFA) or 350 employees, although a secondary entrance for trucks should be allowed.
6. Warehouses of over 750,000 square feet (GFA) or 350 employees.
7. Mobile home park with over 600 units.
8. General office building of 150,000 square feet (GFA) or 500 employees.
9. Medical office building of 60,000 square feet (GFA) or 200 employees.
10. Fast food restaurant of over 6,000 square feet (GFA).
11. Sit down restaurant of over 20,000 square feet (GFA).
(6) Shared driveways and service roads.
(a) Where the Planning Commission determines that reducing the number of access points may have a beneficial impact on traffic operations and safety while preserving the property owner's right to reasonable access, a shared driveway or service drive connecting 2 or more properties or uses may be required. In particular, service drives may be required where recommended in the Master Plan or corridor plan, near existing traffic signals or near locations having traffic volumes and along segments of roadway with a relatively high number of accidents or limited sight distance.
(b) Shared driveways and service drives shall be within a recorded access easement.
(c) The Planning Commission may allow temporary access where the service road is not completed if a performance bond or other financial guarantee is provided which assures the elimination of the temporary access upon completion of the service road. Occupancy permits shall not be issued until such financial guarantee has been submitted to the city.
(7) Driveway Width. The following standards shall apply unless engineering judgement determines that another dimension is more suitable for a particular site.
(a) The standard two-way commercial driveway design shall include 1 ingress lane and 1 egress lane with a combined width of 30 feet, measured from face of curb to face of curb.
(b) Where exit volumes are expected to exceed 1,000 vehicles per day, 100 during peak hours, or in areas where it is determined that undesirable motorist delays will occur, 2 egress lanes may be required. Such driveways shall include 1 15-foot wide ingress lane and 2 11.5-foot wide egress lanes (1 marked exclusively for left turns). In areas where significant pedestrian/bicycle travel is expected, the egress and ingress lanes shall be separated by a 6 to 10 foot wide median with a pedestrian refuge area.
(c) Where driveways are to be located on a road segment having a high accident rate or significant traffic congestion/delays, or where left run access is available through alternative means of access, the Planning Commission may require driveway design and signing which prohibits certain turning movements.
(d) For access arrangements which include 2 one-way driveways, such as a right-turn-in and right-turn-out only arrangements, each driveway shall be 16 feet wide, measured perpendicular to the curb, and angled to minimize the disruption of traffic flow.
(8) Engineering judgement. Engineering judgement shall be utilized to determine the necessary throat length, but in no case shall it be less than 25 feet.
(9) Angle of commercial driveways. Commercial driveways shall be on a 90 degree angle with roadway unless physical modification and/or directional signs are used to enforce intended one-way operations or restricted movements.
(10) Deceleration and acceleration lanes and tapers. Deceleration and acceleration lanes and tapers where warranted by either through traffic conditions or expected high driveway volumes shall be used to avoid the disruption in the flow of traffic.
(1993 Code, § 82-407) (Ord. passed 2-12-2001; Ord. passed 9-10-2001(3))
Editor's note:
Ord. of Feb. 12, 2001, § 82-474, set out provisions intended for use as § 82-471. At the City Clerk's request, these provisions have been included as § 82-407.
Marginal service roads may be required by the Planning Commission, after consultation with the traffic engineer, when it is determined by the Commission that an excessive number of ingress and egress roads may occur with relation to a major or secondary thoroughfare and that reducing the number of points of access to the thoroughfare is in the best interest of the city. Unless the property owner demonstrates that an alternative design would be in the public interest, as determined by the Planning Commission, marginal service roads may be required.
(1993 Code, § 82-408) (Ord. passed 2-25-1991; Ord. passed 5-14-2001; Ord. passed 3-11-2002(1))
