The preliminary plat shall be drawn to a scale on standard twenty four inch by thirty six inch (24" x 36") tracing vellum or Mylar. The accuracy of location of alignments, boundaries and monuments shall be certified by a registered land surveyor licensed to do such work in the state. A workmanlike execution of the plat shall be made in every detail. A poorly drawn or illegible plat is sufficient cause for rejection. The following data shall be submitted as part of the preliminary plat submission:
A. Subdivision Name: The proposed name of the subdivision.
B. Partial Tract Development: Where the plat submitted covers only a part of the subdivider's tract, or is part of a larger vacant area, the plat shall show the location of the subdivision as it forms part of a larger tract or parcel. In such case, a sketch of the prospective future street system of the unplanned parts shall be submitted and the street system of the part submitted shall be considered in the light of adjustments and connections with the future street system of the larger area.
C. Property Location: Sufficient information to locate accurately the property shown on the plat.
D. Boundary Traverse Map: A boundary traverse map of the perimeter of the proposed subdivision. The surveying shall have an error of closure of not greater than one part in ten thousand (10,000). The boundary survey and traverse shall be certified by a land surveyor, registered to practice in the state.
E. Vicinity Map: A vicinity map showing perimeter outline of the plan, accesses, abutting subdivision outlines and names, and other relevant information within one-half (1/2) mile distance of the perimeter of the proposed plat. Scale not less than one inch equals two thousand feet (1" = 2,000').
F. Names And Addresses: The names and addresses of the subdivider, the engineer or surveyor of the subdivision, and the owners of the land immediately adjoining the land to be subdivided.
G. Zoning Changes: Proposed changes to existing zoning district boundaries or zoning classifications, if any.
H. Existing Conditions:
1. Existing sanitary sewers, storm drains, water supply mains and culverts within the tract or within five hundred feet (500') thereof.
2. The location, widths and other dimensions of proposed lots, streets, alleys, easements, parks and other open spaces with proper labeling of spaces to be dedicated to the public.
3. The location, principal dimension and names of all existing or recorded streets, alleys and easements, both within the proposed subdivision and within six hundred feet (600') of the boundary thereof, showing whether recorded or claimed by usage; the location and principal dimensions for all watercourses, including ditches, canals and natural drainage channels, public utilities and other important features and existing structures within the land and adjacent to the tract to be subdivided, including railroads, exceptional topography, airports and approaches to the airport.
4. The location of existing bridges, culverts, surface or subsurface drainageways, areas subject to occasional flooding, marshy areas, swamps, utilities, buildings, pumping stations or appurtenances within the subdivision or within three hundred feet (300') thereof.
5. The location of the nearest elevation bench mark and survey control monument.
6. The owners of the land immediately adjoining the land to be subdivided and the boundary lines of adjacent tracts of unsubdivided land, showing ownership and property monuments.
7. The existing contours at two foot (2') intervals for predominant ground slopes within the tract between level and five percent (5%) grade and five foot (5') contours for predominant ground slopes within the tract over five percent (5%) grade. Elevations shall be based on national geodetic survey sea level data. In cases of level topography through a subdivision, one foot (1') contours may be required.
8. A soils report prepared by a registered civil engineer, soil engineer or engineering geologist, that certifies to the types of soils, the geologic hazards, development restrictions and suitability of the area for subdivision development.
9. Copies of any agreements with adjacent property owners relevant to the proposed subdivision and the substance of all other covenants, grants of easements or restrictions to be imposed upon the use of the land, buildings and structures.
I. Proposed Development:
1. Lot and street layout.
2. Dimension of all lots to nearest foot (which may be scaled values).
3. Total acreage of entire proposed subdivision.
4. Lots and blocks numbered consecutively.
5. Locations and identification of all existing and proposed public and private easements.
6. Existing and proposed street names.
7. Street plans to show proposed grades, curb-gutter and sidewalks.
8. Typical street cross sections.
9. Proposed water facilities, including pipe diameters, valve locations, fire hydrant locations, water sources, water rights, reservoirs, pumps and design calculations.
10. Excavation or grading of areas requiring in excess of three foot (3') cuts or fills.
11. Proposed sanitary and storm sewer systems, indicating pipe diameters, location of detention ponds, manholes, inlets and other pertinent appurtenances with the design calculations.
12. Approximate boundaries of areas subject to inundation or storm water overflows of an intensity estimated to occur with a return frequency of once every one hundred (100) years.
13. The plat shall be drawn to a scale not less than one inch equals one hundred feet (1" = 100'), and shall indicate the basis of bearings, true north point, name of subdivision, name of city, township, range, section and quarter section, block and lot number of the property under consideration.
14. An affidavit that the applicant is the owner, the equitable owner or authorized by the owner, in writing, to make application for the proposed subdivision.
15. Sites, if any, to be reserved or dedicated for parks, playgrounds, schools or other public uses.
16. Sites, if any, for multi-family dwelling, shopping center, community facilities, industry or other uses, exclusive of single-family dwellings.
17. Proposed phases of development. All development and improvements to be continuous and contiguous to abutting developments.
J. Plat Format: The preliminary plat and drawings shall be prepared in the same format as the final plat and shall include the following instruments signed or to be signed and dated:
1. Subdivider's engineer and/or surveyor's signature and seal.
2. Owner's approval.
3. Planning and zoning commission approval.
4. City engineer's approval.
5. District sanitarian's approval. (Ord., 2-29-1996)
