Home My WebLink AboutA001 - Council Action Form dated October 28, 1986 ITEM #: DATE: 10728786 COUNCIL ACTION FORM SUBJECT: Resolution Approving the Conceptual Development Plan of Willow Creek Estate - Fourth Addition BACKGROUND: The Mortensen I Partnership is requesting approval of the Conceptual Develop- ment Plan (CDP) for the Fourth Addition of Willow Creek Estates . The area in question contains approximately 35.8 acres and is generally located east of South Dakota and north of Mortensen Road. This conceptual development plan contains two large lots , with lot 1 being zoned R-2 (PUD) containing 20.7 acres and lot 2 being zoned R-1 containing 15.1 acres. In 1974, the City Council approved a PUD plan for lot 1 of this CDP and now the developer is wanting to proceed with completing this part of the project. Section 23.1 and Section 29.9(5) of the Municipal Code requires that this prop- erty be platted. Therefore the developer is requesting approval of this CDP which is the first step in the platting process. At present, lot 1 is being used for agricultural purposes and lot 2 is being used as a large lot single family residence. The PUD proposal for lot 1 is to include the construction of two 24 unit apartment structures and fifteen 6 unit apartment structures. At this time, the proposal for lot 2 is that it would remain as a large lot single family residence. Water mains, proposed to serve lot 1 are located in Mortensen Road and within the private road in the Willow Creek Second Addition . This CDP proposes to create a looped water system in this area by extending the 8" water main in the Second Addition and connecting it to the 16" water main in Mortensen Road. The developer will be required to install the water mains with fire hydrants for fire protection prior to framing construction on any structure proposed for construction on lot 1. No water main extensions are proposed for lot 2. The sanitary sewer main is currently located in Willow Creek First Addition. This CDP proposes to extend the existing 10" sanitary sewer to the southeast so as to provide sewer service to lot 1. In addition, the sanitary sewer main is proposed to be extended to the north and the south so as to provide sewer service for all of the proposed development in lot 1, plus extend to the south so as to enable further extension for future development. Both the water main and sewer main are proposed to be dedicated to the City as public utilities. The developer is proposing to install a number of private plat or site improve- ments as part of the original PUD plan. These improvements include an inter- nal sidewalk system, a tennis court facility, street lights and a private drive. These private improvements are to be installed prior to the occupancy • 2 • , of any structure on lot 1 or the approval of the Final Plat of this subdivi- sion which ever is first. In the event these site improvements are not installed at the time(s ) specified, the developer must provide a bond to the City as an alternative to installing these private improvements. Street access for lot 1 and lot 2 is provided by South Dakota Avenue and Mortensen Road respectively. A private drive is proposed to be constructed in a northly direction into lot 1 with a loop turn around facility at the north end. This private drive is proposed to accommodate Cy-Ride Bus traffic thus requiring a 7 112" pavement thickness. The developer must submit for City approval as part of the Administrative Plat an agreement which stipulates that maintenance of this private drive will be the responsibility of the owner of lot 1 and that the City will be held harmless from damages that may be caused by Cy-Ride Bus traffic. This agreement must be recorded in the Chain of Title of lot 1. The CDP proposes to provide a green belt access easement to the City which creates an extension of the linear green belt already started in the College Creek area immediately west of South Dakota. This green belt easement is con- sistent with the City's Parks Master Plan and continues the parkway linkage system already started in College Creek. A stipulation to the approval of the Administrative and Final Plat of this addition is that the plat document must contain a note which indicates that this green belt area is to be a no mow, no maintenance area and that no adjacent land owner be permitted to encroach on this area. Encroachment is to include such activities as mowing, dumping or disturbing the area in anyway. Noxious weeds may be controlled by the owners of this green belt. This green belt proposal has been found to be acceptable to the Parks and Recreation Commission. The Development Review Committee and the Planning and Zoning Commission have reviewed this CDP and have recommended that the plan be approved with the following stipulations: 1. The Administrative and Final Plat documents must contain a note that the green belt easement area provided to the City will be a no maintenance area and that no encroachment should occur from adjacent landowners. 2. The developer must submit to the City for approval , as part of the Adminis- trative Plat, an Agreement for maintenance of the private improvements to be constructed on lot 1 . These private improvements are to include the private drive and street lighting. This agreement must hold the City harm- less from damages caused by Cy-Ride Buses and must be recorded in the Chain of Title of lot 1. 3. All private and public improvements must be constructed or a bond provided to the City for completion of these site improvements prior to occupancy of any structure or as part of the Final Plat approval whichever is sooner. 4. The developer must construct the water mains, including fire hydrants, plus the construction of the private drive to an all weather surface prior to framing construction on any structure in lot 1. Further, the developer must maintain the private drive at an all weather surface condition until all construction of the drive is completed. i M • A copy of the Conceptual Development Plan for this addition is attached for your review.
