No subdivision plat shall be approved by either the Commission or by the Board of Supervisors unless it conforms to the following minimum standards and requirement, except those plats referred to in Section 65.04 as Auditor’s plats. 1. Large Lot Subdivision. Whenever the area is divided into lots of such size that there are indications that the lots will eventually be resubdivided into smaller building lots, consideration shall be given to the street and lot arrangement of the original subdivision so that additional minor streets can be opened which will permit logical arrangement of smaller lots. 2. Relation to Adjoining Street System. The arrangement of streets in new subdivisions shall made provisions for the continuation of the principal existing streets in adjoining subdivisions, or for a proper intersection where said streets in the new subdivision shall connect therewith, or their proper projection where adjoining property is not subdivided insofar as they may be necessary for public requirements. The width of such streets in new subdivision shall not be less than the minimum street widths established herein. The street arrangement shall also be such as to cause no hardship to owners of adjoining property when they plat their own land and seek to provide for convenient access to it. The platting of half streets shall be discouraged. Whenever there exists a dedicated or platted half street adjacent to the tract to be subdivided, the other half of the street shall be platted. 3. Street Width. A. The width for major thoroughfares shall conform to DALLAS COUNTY, IOWA CHAPTER 42 the widths designated on the Comprehensive Plan, or as adopted by the Board of Supervisors upon recommendation ---PAGE BREAK--- 9 of the County Engineer. When new subdivisions border present established roads, a 45-foot easement from centerline shall be given for road purposes. B. The minimum width for local residential streets shall be fifty (50) feet, except that in cases where the topography or special conditions make a street of less width more suitable, the Commission and Board may reduce the above requirements. C. Dead-end streets shall not be over six hundred (600) feet in length and shall have a minimum width of sixty (60) feet, unless, because of unusual conditions the Commission and Board shall approve a street of greater length and/or less width. All dead-end streets shall terminate in a circular right-of-way or cul-de-sac with a minimum diameter of one hundred (100) feet or other equally suitable provision for vehicular turning space. D. Easements of not less than five feet in width shall be provided on each side of all rear lot lines and side lines where necessary for poles, wires, conduits, storm and sanitary sewers gas, water, telephone and other utilities. Easements of greater width may be required along lines or across lots where necessary for the extensions of main sewers and similar utilities. 4. Blocks. No block shall be longer than one thousand three hundred twenty (1,320) feet. 5. Lots. A. All side lot lines shall be substantially at right angles or radial to street centerlines unless the Commission shall agree that a variation to this requirement will provide for better street and lot arrangement. Double frontage lots shall be avoided except where essential to provide separation of residential development from major traffic arteries or to overcome specific disadvantages of topography. B. The minimum dimensions for lots shall be in accordance with the bulk regulations of the Zoning Ordinance for the district within which the subdivision is located; provided, however, that the minimum depth for a lot shall be one hundred (100) feet. CHAPTER 42 DALLAS COUNTY, IOWA C. Corner lots shall be of such width as to permit the maintenance of all yard requirements as required by the ---PAGE BREAK--- 10 Zoning Ordinance. D. All lots at street intersections shall have a radius of not less than twenty-five (25) feet at the street corner. A greater radius shall be required for intersections involving one or more major streets. A cut-off or chord may be substituted for the circular arc. E. All lot corners shall be marked with an iron pin capped with the surveyor’s identification. 6. Street Names. Street names for streets which are extensions of existing streets or roads shall be the same. Street names shall be subject to Commission and Board approval. 7. Building Lines. Building lines shall be shown on all lots intended for residential, commercial or industrial use. Such building lines shall not be less than the minimum yard requirements of the Zoning Ordinance for the district within which the property is located. 8. Character of Development. The Commission shall have the right to agree with the subdivider regarding the type and character of development that will be permitted in the subdivision, and may require that certain minimum regulations regarding this matter be incorporated in deed restrictions. Such regulations shall be intended to protect the character and value of the surrounding development and shall also tend to secure the most appropriate development of the property being subdivided. 9. Easements Along Streams. Whenever any stream or major surface water course is located in an area that is being subdivided, the subdivider shall, at his or her own expense, make adequate provisions for straightening, widening or otherwise improving the channel so that it will properly carry the surface water. The subdivider shall also provide and dedicate to the County an easement along each side of the stream, which easement shall be for the purpose of widening, improving or protecting the streams. The width of such easement shall be adequate to provide for any necessary channel relocation and straightening but in no case shall such easement be less than thirty (30) feet. 42.10 IMPROVEMENTS. Before the final plat of any area shall be approved by the Board of Supervisors and recorded, the subdivider DALLAS COUNTY, IOWA CHAPTER 42 shall make and install the improvements described in this section. In lieu of final completion of the minimum improvements before the ---PAGE BREAK--- 11 plat is finally approved, the subdivider shall post a bond, approved by the County Attorney and County treasurer, with the Board of Supervisors, which bond will insure to the County that the improvements will be completed by the subdivider within one year after final approval of the plat. The amount of the bond shall not be less than the estimated cost of the improvements and the amount of the estimate must be approved by the County Engineer. If the improvements are not completed within the specified time, the County may use the bond or any portion thereof to complete same. For plats located in unincorporated areas within two miles of the corporate limits of cities and towns, the Commission and Board may waive the requirements of this section provided they are satisfied that the subdivision regulations of the cities and towns governing the areas within which the subdivision is located are sufficient to insure adequate conformance with these regulations. The minimum improvements installed or for which bond is posted, in any subdivision, before the plat can be finally approved shall be in accordance with the following subsections: 1. The subdivider shall grade and improve all new streets between the right-of-way lines within the subdivided area.

Minimum pavement widths shall be in accordance with the requirements of the County Engineer. 2. The subdivider shall, whenever necessary, grade any portion of the property subdivided into lots so that each lot will be usable and suitable for the erection of residences or other structures thereon. 3.
