Section 42-507 Subdivision Exceptions.

[Ord. No. 4762, 10-2-2023]
1. 
The Commission may approve a subdivision exception from the provisions of this Section where it finds that an undue hardship or practical difficulty may result from requiring strict compliance with this Section. A subdivision exception may be approved so that substantial justice may be achieved and the public interest secured, provided that any such variance shall not have the effect of nullifying the expressed purpose of this Zoning and Subdivision Code.
2. 
No application for preliminary plat which would create conditions requiring a variance or exception from zoning regulations by the Board of Adjustment, shall be submitted to the Commission unless and until the applicant's petition for variance or exception shall have been first approved by the Board of Adjustment.
3. 
No subdivision exception shall be granted by the Commission unless it is found that:
a. 
The granting of the subdivision exception would not be detrimental to the public safety, health, or welfare or be injurious to other property or improvements in the vicinity of the subject property; and
b. 
The conditions upon which the request for subdivision exception is based are unique to the property for which the subdivision exception is sought, are generally not applicable to other properties, and are not self-imposed; and
c. 
Because of the particular physical surroundings, shape or topographical feature of the specific property involved, a particular hardship to the owner would result, as distinguished from a mere inconvenience, depriving the owner of the reasonable use of his/her land should the strict interpretation of these regulations be enforced; and
d. 
The subdivision exception will not in any manner abrogate the goals, objectives, or policies of the Rolla Comprehensive Plan.
4. 
The Commission shall be empowered to grant subdivision exceptions with respect to the improvements and the design standards relative to and arrangement, street location, alignment, the location and alignment of easements, and similar standards. The Commission may establish certain conditions on subdivision exception approval that will, in the judgment of the Commission, substantially secure the purpose of this Zoning and Subdivision Code.
5. 
If denied by the Commission, the City Council shall review the denial for a variance upon a written appeal by an applicant.
6. 
Requests for subdivision exceptions may be submitted concurrently with the review of the preliminary plat; or final plat if it is a minor subdivision. The written subdivision exception request shall state precisely the provisions from which a subdivision exception is needed along with the reasons for the subdivision exception, particularly as the request relates to the conditions of subdivision exception approval.
7. 
Requests for subdivision exceptions may be submitted independent of plat review if the applicant can show good cause why such request was not made when the plat was filed. Such requests must be approved by both the Commission and the City Council.
8. 
The City Council may elect to disapprove a preliminary or final plat based on the approval of a subdivision exception by the Commission.

Section 42-515 Design Requirements - Parks Dedication.

[Ord. No. 4762, 10-2-2023]
1. 
Purpose. A parks dedication is required in order to provide an adequate level of public park facilities and services to new development based on the open space needs generated by the development and to ensure that such development occurs in a manner that is consistent with the components of the City's Comprehensive Plan. This Section should encourage the placement of parks within new residential developments or near or within a walkable distance of such developments, or will provide for the development of neighborhood or community parks by considering cash payment in lieu of parkland dedication.
2. 
Applicability. This provision shall apply to all residentially zoned subdivisions or re-subdivisions for residential uses that have not been previously subject to parkland dedication or fee in lieu of which create additional developable lots. This provision does not apply to boundary line adjustments or lot consolidations. The requirement for a fee-in-lieu payment also applies when a lot is rezoned from a non-residential district to a residential district, to be due prior to issuance of a building permit for development/redevelopment of the lot.
3. 
Prior To Recording The Final Plat. The applicant shall, as part of the final plat process, provide a warranty deed to the City in a form that is acceptable to the City or provide an equivalent fee-in-lieu payment, prior to recording the final plat.
4. 
Dedication Requirements. The area to be dedicated shall be clearly labeled and delineated on the subdivision plat and shall meet the following requirements:
a. 
Topography. At least fifty percent (50%) of the tract shall have a grade of less than four percent (4%). The balance may be covered with slope, streams, ponds, or other natural features. Retention areas or detention basins which are required by the City's stormwater regulations, drainage easements, or water detention areas will not qualify for the parkland requirement.
b. 
Public Use. This requirement shall be in addition to any private open space or recreation facilities designated for the sole benefit of the subdivision residents.
c. 
Location. The parkland shall have access on a public street with a minimum frontage of sixty (60) feet. Consideration shall be given to placing parks where they can be added to by future subdivisions or as an addition to an existing park. Consideration may be given to the existing and planned park facilities in the vicinity.
d. 
Size And Shape. The tract size shall not be less than one (1) acre in size, unless, in the opinion of the Parks and Recreation Director and the Parks Advisory Commission, this land can be added to an adjacent existing park or future park.
e. 
Approval. The Parks Advisory Commission and the Parks and Recreation Director shall recommend the tract as suitable for use as a public park if the requirements listed above have been deemed satisfied before the plat can be approved by the City Council. The area of the tract shall be based upon a calculation using the following schedule:
i. 
R-1, R-2, U-R Districts: five percent (5%) of total residential area subdivided.
ii. 
R-3, R-4 Districts: seven percent (7%) of total residential area subdivided.
5. 
Computation. The percentage of land deeded shall be based upon the total area of the development or subdivision used for residential uses (lots), excluding any non-residential uses. Non-residential uses shall include such areas as right-of-way, dedicated conservation areas, or private amenities; provided, there are no residences on these areas. If, during the subdivision process, a rezoning is proposed for the same property, this provision will apply at the rate that is consistent with the newly proposed zoning district.
6. 
Parks Director. The required dedication or fee is calculated by the Parks Director. The Parks Director will provide a report to the appropriate City departments, the Commission, and the City Council for final determination that describes the suitability of the proposed land to be dedicated and the way in which the parkland dedication requirement was calculated and, if applicable, the way in which the fee-in-lieu of was calculated and the amount due by the applicant.
7. 
Encumbrances. The deeded land shall be free of liens, special assessments, and other encumbrances and shall have all taxes paid to the date of deeding.
8. 
Use Of Dedications. Nothing herein shall prevent the City from using such deeded park property as allowed by Section 77.140, RSMo.
9. 
Fee-In-Lieu Of Park Dedication. If the land available within the subject subdivision proposal does not meet the requirements and stipulations of this Section, a fee-in-lieu of parkland dedication shall apply. The payment shall be calculated at a rate of fifteen thousand dollars ($15,000.00) per acre of the parkland acreage requirements as calculated above. Any fractional parts of an acre shall be prorated. This rate will apply unless the developer can demonstrate to the satisfaction of the Parks Director and the Parks Advisory Commission that the current fair market value should be used.
10. 
Payment Of Fee-In-Lieu. All fee-in-lieu payments shall be deposited into the Parks and Recreation Land Escrow Account. The applicant shall deposit the required amount into this account without recourse or the right of recovery. Such cash deposit shall be made prior to the recording of the final plat.
11. 
Use Of Fee-In-Lieu Payments. These cash payments shall be used for the following purposes in priority as determined by the City Council with the advice and recommendation of the Parks Director and the Parks Advisory Commission:
a. 
Acquisition of neighborhood or community parks within one-half (1.5) mile of the applicable subdivision.
b. 
Improvements to existing parks within one (1) mile of the applicable subdivision.
c. 
Acquisition or improvement of larger regional or community-wide parks.
