A. General Applicability.
In addition to where expressly allowed by conditional use permit (CUP), a PUD shall be a conditional use in the following zoning districts: Mixed Use Medium Density (MU-M) District, Mixed Use High Density (MU-H) District, Community Commercial (CC) District, General Commercial (GC) District, Highway Commercial (HC) District, General Business (GB) District, Light Industrial (LI) District, and Commercial/Industrial (C/I) District. PUDs are not allowed in shoreland areas pursuant to Chapter 7E of this code. The purpose of the PUD provisions is to encourage exceptional development design standards and alternative design opportunities. In general, the standards for development shall be determined by application of the underlying zoning district. In exchange for higher design standards, site preservation techniques, other unique development considerations, and other public benefit, conventional dimensional criteria may be modified or varied. Examples of variations to dimensional standards include reductions in minimum lot areas, lot widths, and setbacks. Except where expressly otherwise stated herein, the PUD provisions are not intended to modify minimum open space requirements, the density of residential dwellings, minimum design standards or requirements for the use or district, utility requirements, landscaping requirements, minimum structure separation, garage or parking requirements, or the quality of the appearance or construction of residential or commercial development. The following provisions apply to all PUD applications:
1. Procedure. A complete Conditional Use Permit application must be made to the City for PUD consideration. The application shall include a subdivision site plan, when applicable, and written narrative of the proposed development. The Planning Commission and City Council must evaluate the application and make a determination on the merits of the proposed project as a PUD, based upon the conditional use permit standards in the City Code. The PUD procedure may occur concurrently with the platting procedures prescribed in Chapter 8 of the City Code. If the PUD is approved by the City Council, the City shall issue a conditional use permit to the applicant, including conditions of approval, and record it with the Anoka County Recorder.
2. Application Materials; Procedure. An applicant shall make an application for a PUD as a conditional use permit subject to the required materials and procedure described in the City Code. In addition, all PUD applications shall be consistent with the following submittal requirements and procedures:
a. The application shall include a written narrative of the proposed development, including all city code provisions for which flexibility is requested. The application shall include a site plan depicting the proposed development and, where applicable, provide details regarding lighting, security, stormwater treatment, open storage locations and details, truck turning movements, refuse and waste disposal, and any other information deemed necessary by the Zoning Administrator.
b. The application shall include a written copy of the homeowners' association documents, if applicable. Such documents shall include provisions governing the maintenance of common areas, including, if applicable, private streets.
c. When necessary, the application shall be accompanied by a Preliminary Plat of the proposed development, consistent with the application requirements of the Subdivision Regulations (Chapter 8, Columbus City Code).
d. The application shall be presented at a City staff meeting to review preliminary PUD eligibility and consistency with City Code requirements and provide comments to the application.
e. The PUD application and Preliminary Plat shall be reviewed concurrently at a City Planning Commission hearing, consistent with the procedures for a review of a conditional use permit.
f. If the PUD is approved by the City Council, the City shall issue a conditional use permit to the applicant, including conditions of approval, and record it with the Anoka County Recorder.
g. When a plat is required, after approval of a Preliminary Plat and PUD, application shall be made for a Final Plat, consistent with the PUD, Preliminary Plat, and documentation required in the Subdivision Regulations.
h. Review and approval of the Final Plat does not require review and recommendation by the Planning Commission, unless the Final Plat is not consistent with the approved PUD and Preliminary Plat.
B. General PUD Standards. The following will apply to all PUD applications:
1. Uses. The uses allowed in a PUD in the Mixed Use Medium Density (MU-M) District, Mixed Use High Density (MU-H) District, Community (CC) District, General Commercial (GC) District, Highway Commercial (HC) District, Genera Business (GB) District, Light Industrial (LI) District, and Commercial/Industrial (C/I) District shall be limited to the permitted and conditional uses as described in the underlying zoning district except as limited by City Council action.
2. Private Streets. Whenever it does not contradict the provisions of this Ordinance as it relates to an adopted transportation plan or the protection of opportunities for reasonable development of surrounding land adjacent to a development proposed in the application, streets which are intended to be kept continuously closed to public travel or that are at all times posted as private streets may be retained as private streets and made a part of the PUD, provided a homeowner association agreement acceptable to the City contains provisions for street maintenance and replacement, and all private streets are constructed according to standards approved by the City.
3. Outlots or Common Open Space. No outlots or other remnants of land shall be included in any plat, except outlots with public access and future development potential.
4. Development Agreement. Any approved PUD shall require a development agreement between the applicant and the City to ensure the approved PUD is constructed and maintained as approved, including but not limited to installation, design, and maintenance of streets, utilities, amenities, or other aspects of the PUD. Any such development agreement shall be recorded against all parcels within the approved PUD.
