Attachment 7- PUD Setbacks CITY OF ClIANIIASSEN z d w NS S Chanhassen is a Community for Life-Providing for Today and Planning for Tomorrow AA MEMORANDUM TO: Todd Gerhardt, City Manager FROM: MacKenzie Walters, Assistant Planner DATE: September 25, 2017 SUBJ: Planned Unit Development Districts Issue The city's Planned Unit Development districts have mandatory minimum project setbacks which can limit the districts intended flexibility. Summary Planned Unit Developments (PUD) are designed to allow the city the maximum amount of flexibility possible in order to create unique and environmentally sensitive developments that would not possible within the confines of the base zoning districts. The section of the city's zoning code which allows it to establish PUDs species standard minimum project setbacks for the different types of PUD districts. These minimum project setbacks can serve to reduce the flexibility of PUD districts and hamper their ability to preserve desirable site characteristics and efficiently use available land. It may make sense to remove these minimum setbacks, in favor of increased flexibility. Relevant City Code Chapter 20-Article VIII. - Planned Unit Development Districts: This article established the intent, standards, and guidelines for using PUD districts. Chapter 20-Article XXV. —Landscaping and Tree Removal: This article establish the minimum screening and buffer requirements for transitions between lower and higher intensity land uses. Analysis PUDs are a tool which allow the city and developers to establish the unique zoning districts that allow for developments that could not be accommodated by traditional zoning categories. Sec. 20-501 states that the intent of Planned Unit Developments (PUDs) is to "offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards"with the understanding that"the development plan will result in a significantly higher quality and PH 952.227.1100• www.ci.chanhassen.mn.us• FX 952.227.1110 7700 MARKET BOULEVARD • PO BOX 147 • CHANHASSEN • MINNESOTA 55317 1 Todd Gerhardt PUD Setbacks September 25,2017 Page 2 of 18 more sensitive proposal". This section goes on to elaborate that applicants seeking this zoning should demonstrate the development will facilitate preservation, sensitive transitions, and design compatibility with surrounding land uses, amongst other criteria. PUDs are best able to serve their intended function when both the city and developers have a high level of flexibility in creating the PUD district. As it is currently written, the PUD ordinance lists general standards for all PUDs. These standards indicate that industrial PUDs adjacent to single-family homes have minimum building and parking setbacks between 50 and 100 feet, depending on screening. All PUDs are required to meet the buffer requirements established by the city's Comprehensive Plan and Chapter 20, Article XXV of the City Code. This configuration establishes a range of setbacks for these types of PUDs and grants the city the flexibility to modify the setbacks based the development's unique features. Sec. 20-506 lists minimum lot sizes and setbacks for single-family detached residential PUDs. These lot sizes and setbacks establish a minimum threshold appropriate for PUDs seeking to create detached single family neighborhoods. Its base interior setbacks are those of the Residential Single Family District,with the option for the Council to reduce the front yard setback to 20 feet. This PUDs exterior setback is 30 feet. It is not clear why a low-density district would need additional setback and screening from other low-density districts. Removing this requirement would still allow the City Council to require a setback or screening if the situation warranted. Sec. 20-508 provides for a high degree of flexibility with no minimum lot sizes or stipulated interior setbacks beyond a 30-foot public right of way setback which the Council can reduce to 20 feet. This district also has a 50-foot exterior setback. The intent of this setback is to provide a transition area between high and medium density residential districts and adjacent low-density single-family districts;however,the screening and buffing requirements established by the comprehensive plan and Chapter 20,Article XXV are also designed to provide the screening and facilitate transitions between uses. While these buffer requirements do not establish minimum setback distances, they do establish a sliding scale requiring an increased density of landscaping as setback distances decrease. Inserting a provision to allow the city to increase or decrease this setback as part of the approval process would grant increased flexibility similar to what is allowed for PUDs creating regional/lifestyle or industrial centers. Sec. 20-509 which governs the creation of PUDs for regional/lifestyle centers has a 30-foot exterior setback,but allows the City Council to increase or decrease the setback as part of the approval process. A similar provision exists for the district's 50-foot setback from residential districts. This configuration provides a base line setback,but maintains the city's ability to customize the PUD's zoning characteristics based on an area's unique features. Variances can be granted from these exterior setback requirements;however, it is somewhat redundant as all PUD ordinances are already subject to public hearings and City Council approval. That being said,the threshold for receiving a variance is higher than that for having the City Council waive a setback requirement. Granting the city a higher level of discretion in the I Todd Gerhardt PUD Setbacks September 25, 2017 Page 3 of 18 relief it grants developers from PUD exterior setbacks will increase the flexibility of the ordinance and the ability to fulfill its intended function. Additionally, adding language allowing the City Council to waive setback requirements as part of the PUD approval process creates equal treatment between the different types of PUDs and eliminates a procedural hurdle. Alternatives 1) No change. The city can grant a variance in cases where these setbacks do not make sense. 2) Amend the PUD Ordinance to remove the required project setbacks. 3) Amend the PUD Ordinance to existing exterior setback from 20-506, and utilize the language from Sec. 20-509 to allow council to waive or increase setbacks for 20-508 appropriate. 4) Amend the PUD utilize the language from Sec. 20-509 to allow council to waive or increase setbacks for 20-508 and 20-506 as appropriate. Recommendation Option 3 would grant PUD districts a level of flexibility in line with their attended function, while establishing guidelines and criteria for altering the base standard. The potential ordinance change would read as follows: ARTICLE VIII. - PLANNED UNIT DEVELOPMENT DISTRICT fill Footnotes: --- (11) --- Editor's note— Section 1 of Ord. No. 149, adopted June 24, 1991, amended Art. VIII, Div. 1, to read as herein set out. Former Art. VIII, Div. 1, §§ 20-501-20-505,pertaining to similar subject matter and derived from Ord. No. 80, Art. V, § 18(5-18-1-5-18-5), adopted Dec. 15, 1986, and Ord. No. 136, § 1, adopted Jan. 28, 1991. DIVISION 1. - GENERALLY Sec. 20-501. - Intent. Planned unit developments offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards. The use of the PUD zoning also allows for a greater variety of uses, internal transfers of density, construction phasing and a potential for lower development costs. In exchange for this enhanced flexibility, the city has the expectation that the development plan will result in a significantly higher quality and more sensitive proposal than would have been the case with the use of other, more standard zoning districts. It will be the Todd Gerhardt PUD Setbacks September 25, 2017 Page 4 of 18 applicant's responsibility to demonstrate that the city's expectation is to be realized as evaluated against the following criteria. Planned unit developments are to encourage the following: (1) Preservation of desirable site characteristics and open space and protection of sensitive environmental features, including steep slopes, mature trees, creeks, wetlands, lakes and scenic views. (2) More efficient and effective use of land, open space and public facilities through mixing of land uses and assembly and development of land in larger parcels. (3) High quality of design and design compatible with surrounding land uses, including both existing and planned. Site planning, landscaping and building architecture should reflect higher quality design than is found elsewhere in the community. (4) Sensitive development in transitional areas located between different land uses and along significant corridors within the city. (5) Development which is consistent with the comprehensive plan. (6) Parks and open space. The creation of public open space may be required by the city. Such park and open space shall be consistent with the comprehensive park plan and overall trail plan. (7) Provision of housing affordable to all income groups if appropriate within the PUD. (8) Energy conservation through the use of more efficient building designs and sightings and the clustering of buildings and land uses. (9) Use of traffic management and design techniques including the provision of transit and pedestrian linkages to reduce the potential for traffic conflicts. Improvements to area roads and intersections may be required as appropriate. Where appropriate, the use of transportation demand management strategies may be required within a project. (Ord. No. 149, § 1, 6-24-91; Ord. No. 377, § 61, 5-24-04) Sec. 20-502. -Allowed uses. Specific uses and performance standards for each PUD shall be delineated in a development plan. (1) Each PUD shall only be used for the use or uses for which the site is designated in the comprehensive plan. Specific uses and performance standards for each PUD shall be delineated in a PUD development plan. (2) Where the site of a proposed PUD is designated for more than one land use in the comprehensive plan, the city may require that the PUD include all the land uses so designated or such combination of the designated uses as the city council shall deem appropriate to achieve the purposes of this article and the comprehensive plan. (3) Residential development in a regional/lifestyle center commercial PUD,may only occur in conjunction with a commercial or office development and may not encompass more than 20 percent of the proposed development. The residential component of a Todd Gerhardt PUD Setbacks September 25, 2017 Page 5 of 18 development may be constructed concurrent or after construction of the commercial or office component, but may not proceed such commercial or office development. The phasing of the residential component shall be reviewed and approved as part of the development plan. (Ord. No. 149, § 1, 6-24-91; Ord.No. 377, § 62, 5-24-04; Ord. No. 488, § 1, 11-23-09) Sec. 20-503. -District size and location. Each PUD shall have a minimum area of five acres except the regional/lifestyle center commercial PUD,which must be a minimum of 30 acres,unless the applicant can demonstrate the existence of one of the following: (1) Unusual physical features of the property itself or of the surrounding neighborhood such that development as a PUD will conserve a physical or topographic feature of importance to the neighborhood or community. (2) The property is directly adjacent to or across a right-of-way from property which has been developed previously as a PUD or planned unit residential development and will be perceived as and will function as an extension of that previously approved development. (3) The property is located in a transitional area between different land use categories or on a collector,minor or principal arterial as defined in the comprehensive plan. (Ord. No. 149, § 1, 6-24-91; Ord. No. 377, § 63, 5-24-04; Ord. No. 488, § 2, 11-23-09) Sec. 20-504. - Coordination with other zoning regulations. (a) Subdivision review under chapter 18 shall be carried out simultaneously with the review of a PUD. The plans required under this chapter shall be submitted in addition to or in a form which will satisfy the requirements of chapter 18 for the preliminary and final plat. (b) Site plan review under article II, division 6 of this chapter, shall be carried out for each nonsingle-family or duplex principal structure that is proposed. (c) PUD plans shall be coordinated with and in compliance with provisions of articles V, VI and VII of this chapter. (Ord. No. 149, § 1, 6-24-91; Ord. No. 377, § 64, 5-24-04) Sec. 20-505. - Required general standards. (a) The city shall consider the proposed PUD from the point of view of all standards and purposes of the comprehensive land use plan to coordinate between the proposed development and the surrounding use. The city shall consider the location of buildings,compatibility,parking areas and other features with response to the topography of the area and existing natural features, the efficiency, adequacy and safety of the proposed layout of streets; the adequacy and location of green areas; the adequacy, location and screening of noncompatible land uses and parking areas. I Todd Gerhardt PUD Setbacks September 25, 2017 Page 6 of 18 (b) The applicant shall demonstrate that the PUD plan offers the city higher quality architectural and site design,landscaping,protection of wetlands, creeks and mature trees and buffering for adjoining properties that represent improvements over normal ordinance standards. (c) Density. An increase/transfer for density may be allowed at the sole discretion of the city utilizing the following factors: (1) Density within a PUD shall be calculated on net acreage located within the property lines of the site in accordance with the land use plan. (2) The area where the density is transferred must be within the project area and owned by the proponent. (3) Density transfer in single-family detached area will be evaluated using the items listed in sections 20-506 or 20-508. Density transfer eligible for multiple-family areas are not permitted to be applied to single-family areas. (4) In no case shall the overall density of the development exceed the net density ranges identified in the comprehensive plan except as specified in policies supporting the city's affordable housing goals. (d) The city may utilize incentives to encourage the construction of projects which are consistent with the city's housing goals. Incentives may include modification of density and other standards for developments providing low and moderate cost housing. Incentives may be approved by the city contingent upon the developer and the city entering into an agreement ensuring that the housing will be available to low and moderate income persons for a specific period of time. (e) Hard surface coverage shall be limited as follows: Comprehensive Plan Designation Hard Surface Coverage (%) Low or medium density residential 30 High density residential 50 Office 70 Commercial (neighborhood or community) 70 Commercial (regional) 70 Industrial 70 Mixed use 70 Individual lots within the PUD may exceed these standards as long as the average meets these standards. (f) Building and parking setbacks from public streets shall be determined by the city based on characteristics of the specific PUD. Parking lots and driving lanes shall be set back at least 20 feet from all exterior lot lines of a PUD. Todd Gerhardt PUD Setbacks September 25, 2017 Page 7 of 18 Where industrial uses abut developed platted or planned single-family lots outside the PUD, greater exterior building and parking setbacks, between 50 and 100 feet, shall be required in order to provide effective screening. The city council shall make a determination regarding the adequacy of screening proposed by the applicant. Screening may include the use of natural topography or earth berming, existing and proposed plantings and other features such as roadways and wetlands which provide separation of uses. PUDs must be developed in compliance with buffer yard requirements established by the comprehensive plan and chapter 20, article XXV, of the Chanhassen City Code. (g) More than one building may be placed on one platted or recorded lot in a PUD. (h) At the time PUD approval is sought from the city, all property to be included within a PUD shall be under unified ownership or control or subject to such legal restrictions or covenants as may be necessary to ensure compliance with the approved master development plan and final site and building plan. After approval, parcels may be sold to other parties without restriction,however, all parcels will remain subject to the PUD development contract that will be recorded in each chain-of-title. (i) Signs shall be restricted to those which are permitted in the sign plan approved by the city and shall be regulated by permanent covenants or design standards established in the PUD development contract. (j) The requirements contained in articles XXIII and XXV of this chapter may be applied by the city as it deems appropriate. (k) The uniqueness of each PUD required that specifications and standards for streets, utilities, public facilities and subdivisions may be subject to modification from the city ordinances ordinarily governing them. The city council may therefore approve streets, utilities, public facilities and land subdivisions which are not in compliance with usual specifications or ordinance requirements if it finds that strict adherence to such standards or requirements is not required to meet the intent of this [article] or to protect the health, safety or welfare of the residents of the PUD, the surrounding area or the city as a whole. (1) No building or other permit shall be issued for any work on property included within a proposed or approved PUD,nor shall any work occur unless such work is in compliance with the proposed or approved PUD. (m) Buffer yards. (1) The city comprehensive plan establishes a requirement for buffer yards. Buffer yards are to be established in areas indicated on the plan where higher intensity uses interface with low density uses and shall comply with chapter 20, article XXV, of the Chanhassen City Code. (2) The buffer yard is not an additional setback requirement. The full obligation to provide the buffer yard shall be placed on the parcel containing the higher intensity use. (3) The buffer yard is intended to provide physical separation and screening for the higher intensity use. As such, they will be required to be provided with a combination of berming,landscaping and/or tree preservation to maximize the buffering potential.To the extent deemed feasible by the city, new plantings shall be designed to require the Todd Gerhardt PUD Setbacks September 25,2017 Page 8 of 18 minimum of maintenance, however, such maintenance as may be required to maintain consistency with the approved plan, shall be the obligation of the property owner. (Ord. No. 149, § 1, 6-24-91; Ord. No. 179, § 3, 11-23-92; Ord. No. 240, § 14, 7-24-95; Ord. No. 315, § 2, 3-26-01; Ord. No. 377, §§ 65-68, 5-24-04; Ord. No. 474, §§ 7, 8, 10-13-08; Ord. No. 522, § 7, 5-23-11) Sec. 20-506. - Standards and guidelines for single-family detached residential planned unit developments. (a) Intent. The use of planned unit developments for residential purposes should result in a reasonable and verifiable exchange between the city and the developer. The developer gains the potential for offering reduced lot sizes and flexibility in development standards which results in a combination of reduced development costs and improved marketing flexibility. At the same time, the city should be offered enhanced environmental sensitivity beyond normal ordinance requirements. Lot sizes should reflect the site's environmental limitations and opportunities and offer a range of housing pricing options. In addition,quality of development, as evidenced by landscaping, construction quality, provision of public/private open and recreational space, should also be enhanced. (b) Minimum lot size. The standard single-family residential PUD allows lot sizes down to a minimum of 11,000 square feet(excluding identified wetland areas from lot calculations).The applicant must demonstrate that there are a mix of lot sizes and proposed housing types consistent with the local terrain conditions, preservation of natural features and open space and that lot sizes are consistent with average building footprints that will be concurrently approved with the PUD. The applicant must demonstrate that each lot is able to accommodate a 60-foot by 60-foot building pad without intruding into any required setback area or protective easement. Each home must also have a minimum rear yard 30 feet deep. (c) Minimum lot width at building setback: 90 feet. (d) Minimum lot depth: 100 feet. (e) Minimum setbacks: (1) PUD exterior: 30 feet.* -- - . . •- -. - . . ' --- ' .. -- ' ' environmental protection will be enhanced. In these instances, a minimum front yard setback of 20 feet shall be maintained. Accessory buildings and structures: Located adjacent to or behind principal structure a minimum of ten feet from property line. (2) Front yard: 30 feet.* (3) Rear yard: 30 feet. (4) Side yard: Ten feet. Todd Gerhardt PUD Setbacks September 25, 2017 Page 9 of 18 *The 30-foot front yard setback may be waived by the city council when it is demonstrated that environmental protection will be enhanced. In these instances, a minimum front yard setback of 20 feet shall be maintained. (f) Protection and preservation of natural features. The applicant must demonstrate that the flexibility provided by the PUD is used to protect and preserve natural features such as tree stands, wetlands, ponds and scenic views. These areas are to be permanently protected as public or private tracts or protected by permanently recorded easements. (g) Landscaping plan. An overall landscaping plan is required. The plan shall contain the following: (1) Boulevard plantings. Located in front yard areas shall require a mix of over-story trees and other plantings consistent with the site. A minimum of one over-story tree must be provided in each front yard. In place of mass grading for building pads and roads, stone or decorative block retaining walls shall be employed as required to preserve mature trees and the site's natural topography. (2) Exterior landscaping and double fronted lots. Landscaped berms shall be provided to buffer the site and lots from major roadways,railroads, and more intensive uses. Similar measures shall be provided for double-fronted lots.Where necessary to accommodate this landscaping, additional lot depth may be required. (3) Rear yard. The rear yard shall contain at least two over-story trees. Preservation of existing trees having a diameter of at least six inches at four feet in height can be used to satisfy this requirement of the PUD and the plans should be developed to maximize tree preservation. (h) Architectural standards. The applicant should demonstrate that the PUD will provide for a high level of architectural design and building materials. While this requirement is not intended to minimize design flexibility, a set of architectural standards should be prepared for city approval. The primary purpose of this section is to assure the city that high quality design will be employed and that home construction can take place without variances or impact to adjoining lots. The PUD agreement should include the following: (1) Standards for exterior architectural treatments. (2) Prohibition against freestanding garages may be required by the city when it is felt that unattached garages will be difficult to accommodate due to small lot sizes. If an attached garage is to be converted to living space at some time in the future, the applicant will have to demonstrate that there is sufficient room to accommodate a two-car garage without variances to obtain a permit. (3) Guidelines regulating the placement of air conditioners, dog kennels, storage buildings, and other accessory uses that could potentially impact adjoining parcels due to small lot sizes. (Ord. No. 179, § 1, 11-23-92; Ord. No. 377, §§ 69, 70, 5-24-04; Ord. No. 542, § 1, 6-25-12) Sec. 20-507. - Controls during construction and following completion. Todd Gerhardt PUD Setbacks September 25, 2017 Page 10 of 18 (a) The use of the land, the construction,modification or alteration of any buildings or structures in a PUD shall be governed by the final development plan. (b) After the certificate of occupancy has been issued, no changes shall be made in the approved final development plan for a PUD except: (1) Any minor extensions,alterations or modifications of existing buildings or structures may be authorized by the city planner if they are consistent with the purposes and intent of the final plan. No change authorized by this section may increase the bulk of any building structure by more than ten percent. (2) Any building or structure that is totally or substantially destroyed may be reconstructed only in compliance with the final development plan unless an amendment to the final development plan is approved. (3) Changes in uses, any rearrangements of lots, blocks and building tracts, changes in the provisions of common open spaces, and all other changes to the approved final development plan may be made only after a public hearing conducted by the planning commission and upon final approval by the city council. Any changes shall be recorded as amendments to the final development plan. (c) Major amendments to an approved master development plan may be approved by the city council after review by the planning commission. The notification and public hearing procedure for such amendment shall be the same as for approval of the original PUD.A major amendment is any amendment which: (1) Substantially alters the location of buildings,parking areas or roads; (2) Increases or decreases the number of residential dwelling units by more than five percent; (3) Increases the gross floor area of nonresidential buildings by more than five percent or increases the gross floor area of any individual building by more than ten percent; (4) Deceases the amount of open space by more than five percent or alters it in such a way as to change its original design or intended use; or (5) Creates noncompliance with any special condition attached to the approval of the master development plan. (Ord. No. 149, § 1, 6-24-91) Sec. 20-508. - Standards and guidelines for single-family attached or cluster-home PUDs. (a) Generally. Single-family attached,cluster,zero lot line,townhouses and similar type dwelling types may be allowed on sites designed for low, medium or high density residential uses by the City of Chanhassen Comprehensive Plan. (b) Minimum lot sizes. There shall be no minimum lot size; however, in no case shall net density exceed guidelines established by the city comprehensive plan. (c) Setback standards/structures and parking: 1 Todd Gerhardt PUD Setbacks September 25, 2017 Page 11 of 18 (1) PUD exterior: 50 feet. The 50-foot PUD exterior setback may be changed, increased or decreased, by the city council as part of the approval process when it is demonstrated that environmental protection or development design will be enhanced. (2) Interior public right-of-way: 30 feet.* *The 30-foot front yard setback may be waived by the city council when it is demonstrated that environmental protection will be enhanced. In these instances, a minimum front yard setback of 20 feet shall be maintained. (3) Other setbacks: Established by PUD agreement. (d) Protection and preservation of natural features. The applicant must demonstrate that the flexibility provided by the PUD is used to protect and preserve natural features such as tree stands, wetlands, ponds and scenic views. These areas are to be permanently protected as public or private tracts or protected by permanently recorded easements. (e) Landscaping plan. An overall landscaping plan is required. The plan shall contain the following: (1) Boulevard plantings. Located in front yards shall require a mix of over-story trees and other plantings consistent with the site. Landscaped berms shall be provided to screen the site from major roadways, railroads and more intensive land uses. In place of mass grading for building pads and roads, stone or decorative blocks retaining walls shall be employed as required to preserve mature trees and the site's natural topography. (2) Exterior landscaping and double fronted lots. Landscaped berms shall be provided to buffer the site and lots from major roadways, railroads, and more intensive uses. Similar measures shall be provided for double-fronted lots.Where necessary to accommodate this landscaping, additional lot depth may be required. (3) Foundation and yard plantings. A minimum budget for foundation plants shall be established and approved by the city. As each parcel is developed in the PUD,the builder shall be required to install plant materials meeting or exceeding the required budget prior to issuance of certificate of occupancy or provide financial guarantees acceptable to the city. (4) Tree preservation. Tree preservation is a primary goal of the PUD. A detailed tree survey should be prepared during the design of the PUD and the plans should be developed to maximize tree preservation. (f) Architectural standards. The applicant should demonstrate that the PUD will provide for a high level of architectural design and building materials. While this requirement is not intended to minimize design flexibility, a set of architectural standards should be prepared for city approval. The primary purpose of this section is to assure the city that high quality design will be employed and that home construction can take place without variances or impact to adjoining lots. The PUD agreement should include the following: (1) Standards for exterior architectural treatments. Todd Gerhardt PUD Setbacks September 25,2017 Page 12of18 (2) Prohibition against freestanding garages may be required by the city when it is felt that unattached garages will be difficult to accommodate due to small lot sizes. If an attached garage is to be converted to living space at some time in the future, the applicant will have to demonstrate that there is sufficient room to accommodate a two-car garage without variances to obtain a permit. (3) Guidelines regulating the placement of air conditioners, dog kennels, storage buildings and other accessory uses that could potentially impact adjoining parcels due to small lot sizes. (Ord. No. 179, § 2, 11-23-92; Ord. No. 240, § 15, 7-24-95; Ord. No. 315, § 3, 3-26-01; Ord. No. 377, §§ 70, 71, 5-24-04) Sec. 20-509. - Standards and guidelines for regional/lifestyle center commercial planned unit developments. (a) Intent. (1) The use of planned unit developments for regional/lifestyle center commercial purposes should result in a reasonable and verifiable exchange between the city and the developer. This district is intended to provide for the development of regional and community scale integrated retail, office,business services, personal services and services to the traveling public near freeway interchanges. It shall strive to create a self-sustaining pattern of land uses with cultural, employment, entertainment, housing, shopping and social components. (2) The regional/lifestyle center commercial district is a mixed commercial district with retail and entertainment uses of a scale and function that serves a regional market. The physical environment emphasizes an attractive, comfortable walking experience for shoppers and visitors. It shall be designed to serve pedestrian and mass transit users as well as automobile traffic. Centers of this type, generally, have at least two major retail anchors and are characterized by the diversity of mixed retail and service uses. Uses within this district should complement existing retail users in the other commercial districts. (3) Development of these centers shall be planned as a group of organized uses and structures to accommodate a sensitive transition between commercial activities such as loading, parking of automobiles, lighting and trash collection and surrounding residential uses. Such centers shall be designed with one theme, with similar architectural style, similar exterior building materials, and a coordinated landscaping theme, but shall avoid monotony in design and visual appearance. Vehicle and pedestrian access is coordinated and logically linked to provide a comprehensive circulation system. (b) Minimum lot size: 10,000 square feet (c) Minimum lot width at building setback: 100 feet. (d) Minimum lot depth: 100 feet. (e) Minimum setbacks: Building setbacks are also a function of the building height. As a building's height increases above 35 feet, the front, rear and project perimeter setback shall Todd Gerhardt PUD Setbacks September 25, 2017 Page 13 of 18 increase on a one to one basis. The increased setback shall only apply to that portion of the building that exceeds 35 feet, e.g., a 40-foot tall building would be set back ten feet (front or rear) at that point where the building height equals 40 feet. A building height may step back, providing the setback/building height ratio is maintained. (1) PUD exterior: 30 feet. The 30-foot PUD exterior setback may be changed, increased or decreased, by the City Council as part of the approval process when it is demonstrated that environmental protection or development design will be enhanced.Building setbacks adjacent to exterior development lot lines abutting an area designated for residential use in the comprehensive plan shall be 50 feet,unless unique circumstances are found which would allow the city to reduce the setback requirement. (2) Front yard: 5 feet. (3) Rear yard: 5 feet. (4) Side yard: 0. (5) Parking: Setbacks (feet): Front: 10 Side: 10 Rear: 10 (6) Parking setback exemptions: a. There is no minimum parking setback when it abuts, without being separated by a street, another off-street parking area. b. Parking along public streets shall provide an appropriate transition, which shall incorporate such elements as landscaping, decorative fencing, public art, berming, etc. c. Parking setbacks adjacent to exterior development lot lines abutting an area designated for residential use in the comprehensive plan shall be 50 feet unless unique circumstances are found which would allow the city to reduce the setback requirement. Unique circumstances include site elevation, separation by natural features such as wetlands or stands of mature trees or substantial visual screening through berming and landscaping. (7) Parking standards shall comply with City Code for type and location.

The applicant must demonstrate that the flexibility provided by the PUD is used to protect and preserve natural features such as tree stands, wetlands, ponds and scenic views. These areas are to be permanently protected as public or private tracts or protected by permanently recorded easements. (h) Landscaping plan. An overall landscaping plan is required. The plan shall contain the following: (1) Boulevard plantings. Located in front yards shall require a mix of over-story trees and other plantings consistent with the site.
