A public hearing is required to make changes in these chapters. We are requesting that the Planning Commission review the proposed revisions to Chapter 20 and recommend an ordinance amendment incorporating the changes. Staff has prepared a strike-through (delete) and bold (add) format to review the proposed changes. ISSUE: Currently patios and driveway expansions are not specifically required to obtain a zoning permit. We have been discovering that without prior review, many of these structures are encroaching into drainage and utility easements or leading to site coverage exceeding code. The intent of the zoning permit is to permit review of a project, prior to its installation, to assure compliance with City Code and ultimately elimination of after-the-fact variance requests. Sec. 20-91. Zoning Permit. (a) A Zoning Permit shall be required for the construction of structures which do not require building permit to determine compliance with zoning requirements such as setback, site coverage, structure height, etc.: Agricultural buildings. Decks less than 30 inches above the ground and not attached to the principal structure. Driveway Expansions. One-story detached accessory structures, used as tool or storage sheds, playhouses, and similar uses, less than 120 square feet in building area. Patios. Permanent fences less than six feet in height. Sport courts. CCAtltlED The City of Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play. Planning Commission June 19,2007 Page 2 of 6 (b) A zoning permit application that fails to meet zoning ordinance requirements shall be denied by the community development director. PROPOSED CHANGE: Add Driveway Expansions and Patios to the list of required improvements to obtain a zoning permit. ISSUE: As part of the expansion of existing buildings and with the construction of office warehouse buildings, the city has encountered difficulties and granted variances from the fac;ade transparency requirements of section 20-1068. Staff has prepared exceptions for structures built prior to adoption of the design standards, where the building's use or function precludes the use of windows in certain areas or on properties with multiple street frontages. For buildings that were built prior to adoption of the ordinance, the city will encourage the use of transparent windows or doors, but would permit a relaxation of the requirement if they are at a minimum maintaining the existing patterns and details of the existing building architecture. For buildings with a use or function that does not readily allow windows, e.g., cooler or freezer areas in stores or warehouse or manufacturing space in industrial buildings, we could relax the standards by not requiring the windows at the lower level, permitting the use of spandrel glass or architectural detailing which provides patterning and shadowing that provides aesthetic interest. Arcades - a series of arches supported on piers or columns. Bosses - a projecting masonry or rock feature or ornament in a wall. Buttresses - a projecting support built into or against the outside of a masonry wall. Clerestories - a portion of the wall rising above the adjacent rooftops and having windows. Colonnades - a series of regularly spaced columns usually supporting one side of a roof structure. Corbeling - an overlapping arrangement of bricks or stones in which each course steps upward and outward from the vertical face of a wall. Embrasures - a small or narrow opening in a wall. Fenestration - the design, proportioning and disposition of windows and other exterior openings of a building. Loggias - a colonnaded or arcaded space within the body of a building but open on one side, often at an upper story. Lunettes - an area in a plane of a wall framed by an arch or vault which may contain a window. Pilasters - a shallow rectangular feature projecting from a wall, having a capital and base and architecturally treated as a column. Portals - a doorway, gate or entrance, emphasized by size and architectural treatment. Quoins - an exterior angle of a masonry wall, or one of the stones or bricks forming such an angle, usually differentiated from adjoining surfaces by material, texture, color, size or projection. Sec. 20-1068. Facade transparency. Fifty percent of the first floor facade 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 facade area. Planning Commission June 19,2007 Page 3 of6 The remaining 50 percent of the first floor 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. , ,;. For buildings with a use or function that does not readily allow windows, e.g., cooler or freezer areas, mechanical rooms, security areas, storage areas or warehouse or manufacturing space in commercial or industrial buildings, the fenestration standards may be reduced. However, the architecture detailing must be provided by the use of upper level windows, the use of spandrel glass or architectural detailing which provides arches, patterning, recesses and shadowing that provide aesthetic interest. Architectural detailing may include such things as change in materials, change in color, and other significant visual relief provided in a manner or at intervals in keeping with the size, mass, and scale of the wall. Architectural detailing may include arcades, arches, bosses, buttresses, clerestories, colonnades, columns, corbeling, loggias, pilasters, portals, quoins, silos, tiling and towers. Additional architectural elements may include the use of awnings, canopies, embrasures, lunettes, plant boxes, recesses and shutters. For buildings that were built prior to September 24, 2001, the city will encourage the use of transparent windows or doors as part of any building expansion. However provided the expansion, at a minimum, maintains the existing patterns and details of the existing building architecture, the proposed expansion would not be required to meet the 50 percent transparency requirement. PROPOSED CHANGE: Amend section 20-1068 to incorporate exceptions to the fayade transparency requirement. Planning Commission June 19,2007 Page 4 of 6 ISSUE: City code requires storage of boats, all-terrain vehicles, snowmobiles and trailers, in the side or rear yard. City code states a required maximum driveway width of 36 feet. The width of a three-car garage could reach 36 feet. This would eliminate the possibility of an addition of bituminous accessory parking within the side yard for recreational vehicle storage. City code does not prohibit four-car garages; however, a variance from the 36-foot width would be required. Staff believes the hard surface requirement would limit the width of driveways. In addition, hard surface expansion into drainage and utility easements can cause drainage problems on the property as well as to adjacent properties. Staff believes drainage should be addressed by the property owner to eliminate drainage issues. Sec. 20-1122. Access and driveways. The purpose of this section is to provide minimum design criteria, setback and slope standards for vehicular use. The intent is to reduce interference with drainage and utility easements by providing setback standards; reduce erosion by requiring a hard surface for all driveways; to limit the number of driveway access points to public streets and to direct drainage toward the street via establishment of minimum driveway slope standards. Parking and loading spaces shall have proper access from a public right-of-way. The number and width of access drives shall be located to minimize traffic congestion and abnormal traffic hazard.

Encroachment in to a side yard drainage and utility easement must be reviewed and approved by the city and may require an encroachment agreement. b. Driveway grades shall be a minimum of one-half of one percent and a maximum grade of ten percent at any point in the driveway. c. Within the right-of-way driveways should access city streets at 90 degrees. d.6. In areas located within the Metropolitan Urban Services Area (MUS A) as identified on the comprehensive plan, driveways shall be surfaced with bituminous, concrete or other hard surface material, as approved by the city engineer. In areas outside the MUSA, driveways shall be surfaced from the intersection of the road through the right-of-way portion of the driveway with bituminous, concrete or other hard surface material, as approved by the city engineer. e.4- On comer lots, the minimum comer clearance from the roadway right-of-way line shall be at least 30 feet to the edge of the driveway. f. &.- For A-2, PUD-R for single-family detached houses, RR, RSF, aflEl R-4 and RLM for single-family detached residential uses, the width of the driveway access shall not exceed 24 feet at the right-of-way line.

Planning Commission June 19,2007 Page 6 of 6 ISSUE: Clarification of ground low profile sign display area within the lOP district. Subsection (1) has a different display area than subsection (2) for the same type of sign. Pylon signs, which are only permitted within the Highway 5 corridor, are allowed 80 square feet of display area and up to 20 feet height. Ground low profile signs within the lOP district have a maximum display area of 64 square feet. The lOP district allows pylon signs on parcels that abut the Highway 5 corridor only; staff would like to expand the lOP pylon to all State Highway corridors, consistent with the commercial districts. Pylon signs are permitted on parcels that abut State Highway corridors within commercial districts. Sec. 20-1304. Industrial Office Park Signs. (1) Pylon or ground 1m'; profile business signs.
