The Plan of subdivision shall be such as to meet the minimum requirements as detailed herein under Section B. A preliminary plat shall be submitted for examination; and to receive consideration at the next subsequent meeting of the Commission, shall be filed with the Secretary of the Commission not less than five days prior to such meeting. Previous to submission of a preliminary plat, subdividers are invited to discuss with tIe Planning Commission or its staff preliminary studies or sketches or problems. Tentative Approval After reference of the preliminary plat to the technical adviser of the Commission for review and report as to stre t and lot layout, aril other features of the plan, and as to compliance with these regulations, and after such negotiations with the applicant for changes in the plat as the Commission may deem advisable, the Commission shall, within a reasonable time, pass upon the preliminary plat as originally submitted or modified and, if approved, shall express its tentative approval, and if disapproved, shall express its disapproval and its reasons therefor. If such action be one of approval, such approval shall not constitute a final acceptance of the plat and shall not be noted on the plat, but shall be deemed merely an expression of approval of the layout submitted on the preliminary plat. The final approval of thefinal plat for record will be considered only after the requirements outlined herein under Section C shall have been fulfilled. Preliminary Plat Three copies of the preliminary plat shalllaccompany the l riwttenh the application submitted to the Commission. pccp y provisions, contain the information, and be accompanied by the material required under the provisions of Section D, and as may be required by the Commission is pursuance of such provisions. 00210 Final Plat The final or record subdivision plat shall be prepared and sub- mitted to the Commission in triplicate by the owner of the property or his authorized representative within one year after the approval of the pre- liminary plat; otherwise the approval of the preliminary plat shall become null and void unless an extension of time is applied for and the application is granted by the Commission. The final plat shall comply with and shall contain the complete data as required under Section E, and shall be accompained by suchother data or material as is described in Section E. Three reproductions of all final or record plats and of the index sheet, if any, shall be furnished. Endorsement All forms, such as endorsements, dedications and certificates, insofar as required to be entered on the plat, shall be in accordance with the standards of the Commission, as on file in the office of its Secretary and except where otherwise required or permitted, shall be signed by the owner of the property. The duplicate and triplicate of the final plat shall contain all signatures, endorsements, dedications and certificates and shall be left with the commission for its files or transmission to other departments. SECTION B GENERAL REQUIREMENTS AND MINIMUM STANDARDS OF DESIGN The following shall be considered as minimum requirements and will ordinarily be varied by the Commission only under the conditions and circum- stances set forth in these regulations. 1. Conformity to Official Plan or Map Subdivision shall be in harmony with the matter plan and or the official map of the City. 2. Relation toAdjoining Street System In so far as the master plan or official map does not indicate the sixe, location, direction and extent of a street, and subject to the regulations hereinafter specified regarding definite minimum widths, t}'e arrangement of streets in a. subdivision shall provide for the continuation of the principal streets existing in the adjoining subdivisions, or of their proper projection when adjoining property is not subdivided, and shall be of a width at least as great as that of such existing streets. A. Where, in the opinion of the Commission, topographical conditions make such continuance or donformity impracticable, or B. in cases where the Commission itself adopts a plan or plat of A neighborhood or area of which the sub- division is a part and this plan or plat provided coordinations with the 00211 street system of the city different from that of said continuations or projections of existing streets and the subdivider's plat conforms to such neighborhood or area plat or plan of the Commission, the Commission may approve the subdivider's plat. Where the plat submitted covers only a part fo the subidvider's tra.dt, a. sketch of the prospective future streets system of the unsubmitted part shall be furnished and the street system of the part submitted shall be considered in the light of adjustments and connections with the street system of the part not submitted. Where a tract is subdivided into lots of an acre or more, the commission may require an arrangement of lots and streets such as to permit e. later resubdivision in donformity with the street requirements specified in these regulations.. 3. Access There shall be no reserve strips controlling access to streets, except where the control of such strips is difinitely placed in the city under conditions approved br the Commission. The subdividing of the land shall be such as to provide each lot, by means of either a public street or way or permanent easement, with satisfactory access to an existing public highway or to an thoroughfare as shown on an official map or master plan. 4. Street Widths The minimum width for main thoroughfares shall be as shown on the city's master plan or official map and shall, hen not indicated on such master plan or offical map, be not less than sixty (60) feet; for minor streets, fifty (50) feet; and for local service streets not over four hundred (400) feet in lenght, forty (40) feet. These widths shall be measured from lot line to lot line. In cases where ;=he typography or other physical conditions make a street of the required mihimum width impracticable, the Commission may modify the above requirements. A half street along adjoining property may be approved. 5. Rounding Street Corners Wherever necessary to permit the construction of curbs having a minimum radius of 25 feet at street corners without curtainling the side- walk to less than normal width, the property line as such street corners shall be rounded or otherwise set back sufficiently to permit such construct- ion. Normally the radius on the property line shall be not less than ten (10) feet. Larger radii may be required b the Commission, when, in its opinion, such design in advisable. 6. Easements Except where alleys of not less than fifteen (15) feet are provided for the purpose, the Commission may require easements, not exceeding 00212 six (6) foot, on each side of all rear lot lines, and on side lot lines where necessary or, in the opinion of the Comm'ssion, advisable, for poles, wires, conduits, storm and sanitary sewers, gas, water and heat mains or other utility lines. Easements of the same or greater width may be required along the lines of or across lots where necessary for the extension of the existing or planned utilities. If in the opinion of the Commission the most suitable and reason- able locations for any of the utilities, such as sewers, storm drains, water and gas pipes and electric pole lines and conduits, which are likely to be required within a subdivision, either for the service thereof os' for service of areas in the surrounding territory, do not lie wholly within the streets, including alleys if any, shown upon the plat, the Commission may require, in so far as reasonable, provision to be made for the location of such utilities on routes elsewhere than within said streets, wither by the dedication of public easements for the same as part of the plat or by the filing of supplementary instruments which will.Ladequately protect the public int€rest in the proper location of said utilities. 7. Dead End Streets Streets designed to have one end permanently closed (Culs de sac) shall be provided at the closed end with a turn -around roadway having a minimum radius for the outside curb of at least thirty (30) feet. 8. Grade of Streets Street grades shall not exceed five per cent for main thorough- fares and five per cent for minor streets; nor be less than one half of one per cent at the gutter. Variation from these grades may, however, be permitted by the Commission where advisable to adjust to topographical conditions. 9. Intersection Angles As far as practicable, acute angles between streets at their inter- sections are to be avoided, and where a deflection angle of more than ten degrees in a street line occurs at any point between two intersecting streets a curve of reasonably long radius is to be introduced. 10. Block Lengths Intersecting streets shall be so laid out that blocks between street lines shall be not more than twelve hundred (1200) feet in length; except that where, in the opinion of the Commission, extraordinary conditions unquestionably justify a departure from this minimum, the Commission may require or permit greater distances between street lines. In blocks over six hundred (600) feet in length, the Commission may require, at or near the middle of the block, a public cross walk- not less than fifteen (15) feet in width for foot traffic. 00213 11, Block Widths The widths of blocks preferably shall be such as to allow two tiers of lots, unless exceptional conditions are, in the opinion of the Commission, such as to render this requirement undesirable. 12,E Lot Arrangement In all quadrangular lots, and so far as practicable all other lots, the side lines shall be at right angles to straight street lines or radial to curved street lines. An arrangement placing adjacent lots at right angles to one another shall be avoided where practicable. D. Lot Sizes The minimum dimensions for residence lots shall be such that in no case shall a residence lot contain less than five thousand square feet (5,000). Corner lots shall have such estra width as will permit the establishment of building lines in both streets. Where alleys are shown, the Commission may limit the depth of lot for the purpose of preventing future alley lots or buildings or may require the establishment of building lines along the alley adequate for the conversion of such alley into a minor street. 14. Building Restrictions If the subdivision does not lie within tl'ie force and effect of an existing zoning ordinance, the Commission may require provision for minimum front, side and rear yards. 15. Neighborhood Unit These regulations concerning minor and local street and court widths, dead-end streets, block lengths and widths, and the size of lots, may be modified by the Commission in the case of a plat for a new town or other large tract of land which provides a community plan with a building - development plan and recreational or other community open space adequate, in the opinion of the Commission, for the circulation, recreational, light and air needs of the tract when fully developed and populated and which provides for such legal restrictions or other legal status as will assure the carrying out of the plan in its entirety. 16. Tree Planting The planting of street trees is optional with the subdivider, but if done, planting plans in duplicate must be submitted to the Commission and receive its approval before planting of street trees is begun. 17. Public Open Spaces Where a small park or other neighborhood recreational open space shown on an official map or on a plan made and adopted by the Commission is located in whole or in part in the applicant's subdivision, the 00214 eta Commission may require the dedication or reservation of such open space within the subdivision for park, ployground or other recreational purposes in those cases in which the Commission deems such requirement to be reasonable.
