As a first step in the process, the City contracted with Municipal Code Corporation, MCC, who proposed changes as well as pointing out conflicts and issues within the code. Secondly, city staff has been reviewing areas of the code with which they work to determine if any changes should be made due to problems in the code, overlapping code requirements, need for clarification, or procedural or process problems. The City Council has previously completed an initial review of Chapters 1 - 17. Chapters 18 and 19 were provided to City Council, but not reviewed. After we have completed the initial review, we will prepare the amendments for hearing and adoption. Please review the draft changes to Chapters 18 and 19 in the binders we have prepared for you. (Please contact me if you require a copy of the draft amendments.) RECOMMENDED ACTION Staff is requesting the City Council review the proposed changes to Chapters 18 - 19 and provide comments and direction on these changes. SUMMARY Following are summaries of the changes being proposed in each chapter: Chapter 18. Subdivisions This chapter deals with the subdivision of land within the city. The majority of the proposed changes deal with procedural issues. The substantive changes include changes to the landscaping and tree protection section of the ordinance and the requirement that sidewalks be required in all new developments. The Planning Commission recommended that the city adopt the largest street width standards for minor arterial and local streets. Staff has proposed that we adopt The City of Chanhassen · A growing ,5orrx¥: mit'¢ ',,vtl ,:;lea Ja~es quiiity 5ci'3ols ,Lsr/anrirl( ls,',rfl(,'~s ~ !h i,, ~:( hLISii}t iS ',z, indin'd ?als arc1 bt;aJlih,!' , [}ark z ,ir'i[ ;; i,: ~ t ,,':; ', Todd Gerhardt September 8, 2003 Page 2 our standard detail plate dimensions. Staff has proposed language to clarify that the 60 x 60 foot building pad was for tree removal calculations. Chapter 19.Water, Sewer and Sewage Disposal This chapter deals with municipal water and sewer service and individual septic treatment systems (ISTS). Many of these requirements are covered by state codes and may be deleted. The proposed changes implement state requirements. Following are additional revisions that have not been provided previously: Sec. 18-40. Same--Data required. (2) f. Topographic data within the property to be subdivided and one hundred (100) feet beyond the property boundary, showing contours as follows: two foot intervals where slope is ten (10) percent or less; five foot intervals where slope is ten (10) to fifteen (15) percent; ten-foot intervals where slope is greater than fifteen (15) percent. All areas of the subdivision to be platted with a slope greater than twenty-five percent must be clearly indicated. However, on undevelopable sections or larger acre lots topographic data may be reduced to significant physical characteristics, such as top and toe of slope, if in the opinion of the city the area is viewed as unsuitable for future subdivision. Location and elevations of on-site and abutting water courses, lakes, wetlands, rivers, streams, and marshes at date of survey and their ordinary high water mark plus approximate high and !ow normal water elevations shall also be shown. A wetland delineation report and surveyed wetland line for all jurisdictional wetlands on or within one hundred (100) feet of the property boundary. The delineation shall be no more than three (3) years old, unless accompanied by documentation demonstrating the delineation has been reviewed in the past three (3) years and is accurate or revised to reflect changes on- site. Where the subdivision borders a lake, river or stream, a meander line shall be established at an elevation two (2) feet above the recorded high water elevation of the lake, river or stream. Flood plain areas, location of wooded areas, rocky outcrops, power transmission poles and lines and other significant physical features shall also be shown. Inclusion of the wetland delineation is for clarification purposes, since these reports are required of subdivisions. The requirement .for a meander line two feet above the recorded hi~,h water elevation is unnecessary.(7~8~03) (4) c. A drainage plan for the area indicating the direction and rate of natural storm water runoff and those unaltered areas where storm water collects and percolates into the ground. A proposed drainage plan for the developed site indicating the direction and rate of runoff, the path of all storm water discharge to the public storm water infrastructure and those areas where storm water will collect and percolate into the ground shall also be included. Storm water management shall be consistent with the city's storm surface water management plan. Todd Gerhardt September 8, 2003 Page 3 *The first change will ensure that staff is able to evaluate any inconsistencies in data or problems that may occur as a result of a subdivision's discharge through adjacent properties. The second change will make the language consistent with the language used throughout the rest of the city code.(7/9/03) Sec. 18-61. Landscaping and tree preservation requirements. (a) Required landscaping/residential subdivision. (1) Each lot shall be provided with a minimum of one (1) deciduous tree to be placed in the front yard. The type of tree shall be subject to city approval. (The city will provide a list of species). Coniferous trees must be at least six (6) feet high and deciduous trees must be at least two and one-half (21/2) inches in diameter at the time of installation. This requirement may be waived by the city where the applicant can demonstrate that a suitable tree having a minimum diameter of two and one-half (21/2) inches for deciduous and six-foot height for evergreen and four (4) feet above the groumt is located in an appropriate location on the lot. The following trees may be used to meet planting requirements: *This distinction is confusing and unnecessary. Deciduous added for clarification purposes. The landscaping is provided as part of the landscaping plan for the project prepared by a landscape professional. The ordinance contains the list of species. (7/15/03) Eliminate primary and secondary specimen since they are all deciduous trees.

Deletions include redundant mentions and poor selections. Sec. 19-28. Water use restriction. Use of the city water supply system for lawn and garden sprinkling, irrigation, car washing or other nonpotable uses shall be limited to an odd-even schedule corresponding to property address effective each year from May I to September 30. Whenever the city council or, on a temporary basis, the public works director and/or the city manager or city manager's designee, shall determine that a shortage of the water supply threatens the city, they may, by resolution, further limit the use, times days and hours during which water may be used from the city water supply system. Special permit consideration will be given for those property owners with new seed or sod if in the opinion of the public works director sufficient water for such permits is available. Property owners installing an automatic or underground irrigation system are required to install a rain sensor device. Existing irrigation systems are required to retrofit to install a rain sensor device at such time as improvement or extension of the system valued at or above $1,000.00 or requiring a plumbing permit are done. The first violation of the provisions of this ordinance in any calendar year shall result in a written warning from the city. Subsequent violations will result in a penalty fee schedule approved by City Council. The penalty will be added to the next water bill for the premises. *Recommended by the public works director.
