(d) Camping. * Camping to be provided by the city attorney. *MCC recommendation (a) (3). Sec. 20-905. Single-family dwellings. All single-family detached homes shall: (1) Be constructed upon a continuous perimeter foundation that meets the requirements of the state building code. (2) Conform to the following standards for living areas: a. If a one-story rambler design, have an area of nine hundred sixty (960) square feet. b.

A two-car garage must be provided with the single-family structure. (3) Have an earth covered, composition, shingled or tiled roof or other materials approved by the Un'~f~m~ Minnesota State Building Code as adopted and amended by the city. (4) Receive a building permit. The application for a building permit in addition to other information required shall indicate the height, size, design and the appearance of all elevations of the proposed building and a description of the construction materials proposed to be used. (5) Meet the requirements of the Unlf.~:':n Minnesota State Building Code as adopted and amended by the city or the applicable manufactured housing code. *Minnesota State Building Code applies. Sec. 20-908. Yard Regulations. The following requirements qualify or supplement district regulations. Yard measurements shall be taken from the nearest point of the wall of a building to the lot line in question, subject to the following qualifications: (1) Every part of a required yard or court shall be open and unobstructed. 2 (2) A yard, court, or other open space of one (1) building used to comply with the provisions of this chapter shall not again be used as a yard, court, or other open space for another building. (3) Except as provided in the business, industrial, and office districts, the front yard setback requirements shall be observed on each street side of a comer lot; provided, however, that the remaining two (2) yards will meet the side yard setbacks. (4) On double frontage lots, the required front yard shall be provided on both streets. Whenever possible, structures should face the existing street. (5) The following shall not be considered to be obstructions (variances granted from a required setback are not entitled to the following additional encroachments): Into any required front yard, or required side yard adjoining a side street lot line, cornices, canopies, eaves, or other architectural features may project a distance not exceeding two (2) feet, six (6) inches; fire escapes may project a distance not exceeding four (4) feet, six (6) inches; an uncovered stair and necessary landings may project a distance not to exceed six (6) feet, provided such stair and landing shall not extend above the entrance floor of the building; bay windows, balconies, open porches and chimneys may project a distance not exceeding three (3) feet; unenclosed decks and patios may project a distance not exceeding five (5) feet and shall not be located in a drainage and utility easement. Other canopies may be permitted by conditional use permit. b. The above-named features may project into any required yard adjoining an interior lot line, subject to the limitations cited above. Porches that encroach into the required front yard and which were in existence on February 19, 1987 may be enclosed or completely rebuilt in the same location provided that any porch that is to be completely rebuilt must have at least a ten-foot minimum front yard. Subject to the setback requirements in section 20-904, the following are permitted in the rear yard: enclosed or open off-street parking spaces; accessory structures, toolrooms, and similar buildings or structures for domestic storage. Balconies, breezeways and open porches, unenclosed decks and patios, and one-story bay windows may project into the rear yard a distance not to exceed five (5) feet. e. Into any required front, rear, or side yard: driveways, sidewalks, stand wire ag~c::!txr~ fences and retaining walls. The intent of this section is to allow homes built prior to February 19, 1987 to add an open porch as an architectural feature to define the entrance into a residence or update a front elevation. Homes built prior to February 19, 1987 may have open porches and/or balconies that encroach into the required front yard a distance not exceeding ten (10) feet, provided they maintain a minimum front yard setback of twenty (20) feet. The ten (10) feet shall include the roofline, support columns, and steps. This area shall not be enclosed nor screened with mesh, glass, or other similar material. Homes that are on the National Register listing or have been considered eligible for listing on the National Register shall be excluded from this ordinance unless approved by the National Historical Registrar's Office. (6) The placement of any structure within easements is prohibited. Structures may be allowed within an easement with an encroachment agreement if they do not alter the intended use of the easement. A driveway or sidewalk from the street to the house crossing drainage and utility easements at the front of the property are exempt from this requirement. *Currently, staff does not allow the placement of any permanent structures (i.e., decks, retaining walls, sheds, etc. ) within easements. Fences and other items may be allowed through the use of an encroachment agreement. Staff will review the placement of each proposed structure and, if they do not alter the intended use of the easement, will allow the structure with an encroachment agreement. Sec. 20-909. Outdoor storage. As otherwise regulated, all outdoor storage is prohibited except: (1) Clothes line poles and wires. (2) Construction and landscaping material currently being used on the premises. (3) Swings, slides and other play equipment. (4) Outdoor furniture and lawn and garden equipment. (5) Wood for burning in a fireplace, stove or furnace provided it is stored as follows: a. In a neat and secure stack, not exceeding four (4) feet. b. The wood stack is not infested with rodents. c. The wood is not kept in a front yard. (6) Continued storage of a property owner's or property lessee's, who resides on the property, boats, all-terrain vehicles, and snowmobiles and trailers may be stored in the side or rear yard behind the required front setback. 4 (7) Outside storage of tires is prohibited. (8) PODS (personal on demand storage) and roll-off dumpsters may be located a property a minimum of six feet (6') away from the house for fire protection and at least ten feet (10') from any property line. Such containers may be kept on site for a maximum of 30 days per year. An extension of the 30 days may be granted by the city if the container is used in conjunction with a valid and ongoing building permit. *The city has had problems with individuals using there yards for the storage of other peoples property. This can create unsightly conditions. Additionally, this may become a commercial operation which should be located in commercial or industrial districts, rather than in residential neighborhoods. PODS and roll-offs are not currently regulated. Occasionally, they can be a problem for neighbors. The city does have a permit process for locating such structures within the public right-of-way. Sec. 20-913. Lighting. (New subsections (d) and (e)) (a) Glare, whether direct or reflected, as differentiated from general illumination shall not be visible beyond the limits of the site from which it originates. (b) No light which is flashing, revolving or otherwise resembles a traffic-control signal shall be allowed in any area where it could create a hazard for passing vehicular traffic. State law references: Similar provisions, M.S. § 169.073. (c) Lighting fixtures on poles shall comply with the following: (1) All fixtures must be shielded, high pressure sodium with a total cutoff angle equal to or less than ninety (90) degrees. (2) Fixture height shall not exceed thirty (30) feet. Recreational facility fixtures shall not exceed sixty-five (65) feet in height. (3) Photometrics shall incorporate existing light fixtures, public or private, that may impact the site. (4) All outdoor light fixtures existing and legally installed prior to February 22, 1999, are exempt from the requirements of this article, unless work is proposed in any one (1) year period so as to replace fifty (50) percent or more of the existing outdoor light fixtures, or to increase to the extent of fifty (50) percent or more the number of outdoor light fixtures on the premises. (d)Wall mounted lighting shall comply with the following: (1) All fixtures shall be shielded with a total cutoff angle equal to or less than 90 degrees. (e) Lighting shall not be directed skyward except for lighting designed for illuminating the United States of America Flag. *It was the intent of the lighting ordinance to reduce or eliminate general lighting of the night sky. However, as written, the ordinance would perrnit wall mounted lighting to be directed skyward or spotlights located on the ground to shine skyward. While section (a) implies this prohibition, staff recommends that we clarify the issue. Sec. 20-919. Telephone equipment buildings. Telephone equipment buildings are allowed in all zoning districts as an cen~:~ona] ancillary use subject to the following standards: (1) The site must provide landscaping as required in article XXV. (2) The driveway surface shall be surfaced with a hard, all-weather, dust free and durable surfacing material. (3) The applicant shall receive an access permit from the regulating agency. (4) The building shall meet the required setbacks of the district in which it is located. (5) The equipment building shall be architecturally consistent with surrounding structures. (Ord. No. 80, Art. VI, § 26, 12-15-86; Ord. No. 80-B, § 1, 6-15-87) *Utility services are a permitted use in all districts. If the city has these standards that must be followed, it does not make sense to say that they must also go through a conditional use permit process. The city regulates communication towers as a conditional use; the equipment buildings are usually ancillary to those, lf it is truly felt that these structures require a conditional use permit, we should revise the district regulations to state as such and add these criteria to Chapter 20, Article IV, Conditional Uses, rather than leaving it in the supplemental regulations.. Sec. 20-920. Privately Owned Underground Amenities Privately owned underground amenities such as but not limited to irrigation systems and invisible dog fences shall not be allowed in the public right-of-way. Neither shall these items be allowed in any City easement without an encroachment agreement. The City shall not be responsible for the repair or replacement of any such amenity unless such responsibility is agreed to by the City. *The city currently does not regulate the installation of these amenities. As these items have become more common, the city is running into more and more issues with them as part of the city's operations. Sec. 20-978. Occupations prohibited. (-t-) Contractors' yards/landscaping businesses are prohibited. *MCC recommendation. If we develop a list, then we will number them. Fences Sec. 20-1017. Permit. A bu~!~ing permit shall be obtained for any permanent fence installed for any purpose, including underground (invisible) fencing, other than an agricultural purpose prior to installation of same. The installation of temporary or seasonal fencing, e. g., snow fencing, garden fencing, etc., without permanent posts is exempt from this requirement. A site plan showing the location of the fence shall be submitted with the permit application. The bu~!~ng zffic~al city may require a fe~-e permit applicationt to provide a registered land survey establishing property lines. A building permit, in lieu of a zoning permit, shall be required for fences in excess of six (6) feet in height and retaining walls in excess of four (4) feet in height. *To clari[y that temporary fencing does not require a permit. Building permits are not required for fences less than 6 feet tall by the state building code. This relates to the changes proposed in Article 11, Division 5 for goning permits. Sec. 20-1019. Loc~ion. (a) Generally. All fences and retaining walls shall be located entirely upon the property of the fence or retaining wall owner unless the owner of the adjoining property agrees, in writing, that said fence or retaining wall may be erected on the property line of the respective properties. Such agreement shall be submitted at the time of building permit application. Encroachment into a City easement shall require an encroachment agreement between the property owner and the city. Fences shall not be placed within the public right-of-way. (b) Wetlands. No fences shall be permitted below the ordinary high water mark of a wetland or within the required wetland buffer area. 7 (c) {Buffers.I- No fences shall be permitted between a required landscape buffer and a collector or arterial street. (d) Temporary fences. Temporary fencing, such as fencing installed to enclose a seasonal garden or snow fencing in winter, may not be located within the front yard setback. Snow fencing shall not be located within any drainage or utility easement. *The city has treated retaining walls as a type offence. This amendment clarifies that policy. The city does not currently issue building permits for temporary fencing. It is felt that providing location standards will address concerns that people have. Sec. 20-1025. Retaining Walls Retaining walls exceeding four (4) feet in height, including stage walls which cumulatively exceed four (4) feet in height, must be constructed in accordance with plans prepared by a registered engineer or landscape architect and shall be constructed of brick, concrete or natural stone. Artfficial material may be approved if appropriate. A permit is required for the construction of retaining walls. *Retaining walls are mentioned in sections 20-118, site plans, and 20-1183, landscaping. They should be located in the fences and walls section of the supplemental regulations. Staff is recommending that those sections be deleted. Sec. 20-1048. Compliance with technical code. (a) Standard drawings of the structural components of the wind energy conversion system and support structures, including base and footings shall be provided along with engineering data and calculations to demonstrate compliance with the structural design provisions of the Unifz:-m Minnesota State Building Code as adopted and amended by the city. Drawings and engineering calculations shall be certified by a registered engineer. *State Building code prevails. Sec. 20-1055 WECS shall not have affixed or attached any lights, reflectors, flashers or any other illumination, except for illumination devices required by FAA Regulations part 77 Objects Affecting Navigable Air Space" and FAA Advisory Circular ....... 70/7460 1K CHG1 Ap il 15 200~ e ..... ;.~. ,h'm -c,. ...... ;^~ ~; g a d *MCC and city attorney recommendation. 8 Sec. 20-1065. Material and detail. All manmade architectural, landscape, and paving materials shall reflect the highest quality possible and should be used in a manner suitable to the nature of the material, its role in the design, general durability, expected level of use or abuse, weathering characteristics, and ease and frequency of maintenance. The following materials or equivalent materials are acceptable: * Brick * Stone * Glass * Textured masonry units * Wood, consisting of lap siding with an exposure no greater than seven (7) inches or wood shakes; surfaces must be painted; * Stucco * Tilt up concrete panels that are grid or brick like in appearance Accent material may occupy up to fifteen (15) percent of the building's facade. These may include metal, glass block, spandrel glass or similar materials approved by the city. GRAPHIC LINK: Material and Detail The following may not be used in any visible exterior application except when specifically permitted by the city in areas with limited public view or accent areas: * Plain/painted poured concrete panels "cast in place" * Painted brick * Painted concrete panels * Painted rock faced block *Unadorned plain or painted concrete block * Tilt-up concrete panel that are ribbed or corduroy in appearance * Prefabricated steel or sheet metal panels * Reflective glass * Aluminum, vinyl, fiberglass, asphalt or fiberboard siding * EFIS (exterior finish and insulating fin]:~ system) may be used as an accent but not a primary material *Besides being exterior finish insulating system, there have been a series of variances regarding the limitation of EFIS. Variances have been approved for the use o[more than 15 percent EFIS on the Chanhassen Community Bank Building and the Northcott Inn & Suites, 16 and 26 percent, respectively. Additionally, we have other buildings in the community that exceed these percentages, e.g., Bokoo Bikes (56 percent), Bell Mortgage building (33 percent), Perkins, and Americana Bank to name a few. 9 From an aesthetic standpoint, EFIS is no different than stucco, which is permitted. So the question becomes is it a maintenance issue, e.g., poor drainage or easily damaged, or is there another issue that needs to be addressed? Sec. 20-1068. Facade transparency. Fifty (50) percent of the first floor ~ fagade that is viewed by the public shall be designed to include transparent windows and/or doors to minimize expanses of blank walls. (Reflective glass is not permitted). If the building is a one-story design and the first floor elevation exceeds 12 feet, then only the first 12 feet in building height shall be included in calculating the faqade area. The remaining fifty (50) percent of the first floor etevatio~ facade that is viewed by the public, shall be designed to include any or all of the following: * Landscape materials (plant material, vertical trellis with vines, planter boxes, etc.) * Architectural detailing and articulation that provides texture on the facade and/or parking structure openings. *Faqade is defined as the area of the building wall from grade to the top of the parapet or eves and the entire width of the building elevation. This should clari[y that windows and doors should represent 50 percent of the wall area for the first floor. Additionall¥, we want to limit the height of the building used to calculate the faqade area for building which may be one-story, but have a height of 20 - 24 feet or more, e.g., Tires Plus or most industrial office buildings which need the higher building height to accommodate warehouse spaces. 10 PODS and Roll offs Survey Page 1 of 3 Generous, Bob From: Angela Auseth Sent: Thursday, January 15, 2004 2:17 PM To: Generous, Bob Subject: PODS and Roll offs Survey PODS and Roll offs Survey Burnsville: · All outdoor storage requires a conditional use permit · Parking and Storage of certain vehicles: Automotive vehicles or trailers of any kind or type without current license plates shall not be parked or stored on any residentially zoned property other than in completely enclosed buildings.

Sec. 20-1118. (a) Design of parking stalls and drive aisles. (a) Parking spaces shall be designed in conformance with the following: parking stalls shall have a minimum paved dimension of eight and one-half feet by eighteen (18) feet. Stall and aisle dimensions shall be as noted below for the given angle: Angle Curb Length Stall length Aisle 45 degree 12.0' 18.0' 13.5' * 60 degree 10.0' 18.0' 18.5' * 90 degree 8.5' 18.0' 26' Parallel 20.0' 8.0' 22' *One-way aisles only. *** Dead end aisles must be provided with a twenty-six (26) feet by ten (10) feet unencumbered area at the end to facilitate vehicle turning movement. *This requirement applies to all dead-end aisles and therefore should not be a note (***) Sec. 20-1122 (a) Access and driveways For the first 20 feet from the front property line, driveways shall have a minimum of 10 foot setback from the side property line. Beginning at 20 feet from the front property line, driveways may have a minimum 5 foot side yard setback unless an encroachment agreement is received from the city in which case the side yard setback may be reduced. *The language is confusing. Can you be up to the property line from the front of the lot to 20 feet back and then must maintain a 5 foot side setback, unless you get an encroachment agreement. Staff has drafted a revision, which we believe, more clearly defines the intent of this criteria ? Sec. 20-1124 (2) f. Required number of on-site parking spaces. f. Dwelling: 1. Single-family--Two (2) parking spaces, both of which must be completely enclosed.
