1193.03 LAND NOT SUITED FOR DEVELOPMENT.
(a) General Provisions. If the Planning Commission, upon recommendation of the City Engineer, finds that land proposed for subdivision development is unsuitable due to flooding, poor drainage, topography, landslip potential, inadequate public facilities, or other condition that may be detrimental to the general health, safety or welfare of the public, and if it is determined that the land should not be developed for the purpose proposed, the Planning Commission shall not approve such subdivision unless adequate methods are proposed by the Owner/Developer for alleviating the problems that would be created by development of the land, subject to the approval of the City Engineer.
(b) Land Subject to Flooding. The subdivision of lands within areas subject to flooding shall be subject to the standards and regulations of Chapter 1329 of the Codified Ordinances, and shall, in addition, be subject to the following requirements:
(1) No subdivision or part thereof shall be approved if the proposed subdivision development will, individually or collectively, significantly increase flood flows, heights or damages.
(2) No subdivision, or part thereof, shall be approved which would substantially affect the storage capacity of the flood plain.
(3) Buildings or structures shall not be permitted in floodway areas. Sites for these uses may be permitted outside the floodway if the sites or structures are elevated to such height that the lowest floor of the structure is least one (1) foot above the 100-year base flood elevation, as established by the Federal Emergency Management Agency (FEMA), and/or other authorized agency, in a flood study or report approved by the City. Required fill areas must extend a minimum of fifteen (15) feet beyond the limits of the structure(s) or required improvement(s).
(4) When the Planning Commission determines that only part of a proposed plat can be developed in compliance with these requirements, it shall limit development to only that portion.

Generally, such a plan shall be required for, but not limited to, major subdivisions where the total area of the subdivision is more than one (1) acre in size, or if the subdivision is located where average slope exceeds five percent (5%). In addition, the City Engineer may require the Owner/ Developer to submit erosion and sedimentation plans for any established lot where development is proposed to occur.
Erosion and sedimentation plans for subdivisions shall be prepared by a Professional Engineer, and indicate the techniques and location of devices to be used to control erosion both during construction and permanently, and include a schedule for installing those devices. Erosion control plans shall be based on the control of erosion on-site, with the objective of eliminating or minimizing erosion and sedimentation impacts off-site. Techniques, devices or measures used shall be reviewed and approved by the City Engineer.
All erosion and sedimentation control devices shall be in place at the start of construction activity.
(Ord. 27-11. Passed 3-14-11.)

(b) Construction Site Runoff Control. The Owner/Developer shall use adequate measures to minimize erosion and other negative water quality impacts as a result of construction and development activity. The Planning Commission shall have the authority to require a Storm Water Pollution Prevention Plan in those cases where the scope and scale of the development warrants, as recommended by the City Engineer. The Plan shall be prepared by a Professional Engineer or other certified professional and shall be developed utilizing current industry standards and effective Best Management Practices (BMPs). As part of the plan, the Owner/Developer shall install, inspect and keep records of inspection, and maintain BMPs throughout the duration of the permit. The City Engineer may inspect the construction site for compliance with the Storm Water Pollution Prevention Plan and, if found lacking, may issue a permit violation, stop work order, fine or other measure to ensure compliance.
(c) Post Construction Runoff Control. Post construction storm water runoff control shall be addressed in the design phase of proposed subdivisions. Both structural and nonstructural post construction BMPs will be considered. Use of riparian setbacks, green space preservation, porous pavements, water quality swales and grass filter strips are a few methods to be considered. Specific sites within the proposed subdivision may be inspected for compliance and, if found lacking, the City Engineer may issue a permit violation, stop work order, or fine to ensure compliance. Fines as defined by separate ordinance may be levied by the City as soon as one (1) week after notification of violation.
(d) Storm Water Drainage.
(1) General. No subdivision plan or plat shall be approved that does not make adequate provision for storm water runoff and flood waters. The Planning Commission shall have the authority to deny subdivision approval for areas of extremely poor drainage, including subdivisions in areas dominated by hydric soils. In any subdivision, the storm drainage system shall be separate and independent of any sanitary sewer system.
(2) Preservation of Natural Drainage Courses. Generally, the natural flow of all existing drainage courses, including underground drainage systems, shall be accommodated. Such underground systems, including farm field tile systems, shall be identified and mapped as part of the preliminary plan.
No natural drainage course shall be altered and no fill, buildings or structures shall be located unless provision is made for the flow of storm runoff and/or surface water. The City Engineer may require an easement to be provided on both sides of the existing surface drainage course adequate for the purpose of future widening, deepening, enclosing or otherwise improving said drainage course. If such drainage course crosses private property, easements must be obtained by the Owner/Developer for construction and future maintenance. These easements must be shown on the Construction Plans, including the volume and page number of the recorded easement.
(3) Outlets. No subdivision plan or plat shall be approved by the Planning Commission unless an adequate outlet for storm water, as shown on the plan or plat, is approved by the City Engineer. The Owner/Developer shall pay all costs associated with an analysis performed and submitted by a Professional Engineer demonstrating that an adequate outlet for storm water runoff exists. Generally it will be necessary to pipe storm water to an adequate watercourse, stream or existing storm system which has the capacity to accommodate the flow, or to utilize acceptable on-site water retention methods adequate to minimize excessive off-site storm water flows.
(4) Submittal Data. Culverts and other components of storm water conveyance systems that cross streets or roadways shall be designed so as to adequately address the ten (10) year storm under residential streets and the fifty (50) year storm under collector and arterial streets. The City Engineer may require the Owner/Developer to pay for an analysis of the existing storm water system by a Professional Engineer to determine how best to connect the proposed development to the existing system or any required improvements downstream so as not to overload the system. The post development runoff rate may not exceed the predevelopment runoff rate as determined by the 100 year storm event.
(e) Culverts. All culverts utilized in subdivisions shall have the appropriate headwalls and/or other structures and improvements to protect the facility.
(f) Open Drainage Channels. The determination as to whether a specific drainage course shall be enclosed shall be made by the City Engineer. In those cases where an open channel is determined to be acceptable, the cross section and profile of the open channel and its banks shall be approved by the City Engineer.
(Ord. 27-11. Passed 3-14-11.)

(b) Classification, Street Widths and Street Grades. The arrangement and classification of all streets in newly developed areas shall conform to the Thoroughfare Plan. For streets not indicated on the Thoroughfare Plan, the arrangement shall provide for appropriate extensions of existing streets. The Planning Commission shall make the final determination as to the classification of any new street, based on the potential development of the site, and its potential traffic volume as expressed in ADT (Average Daily Traffic), the character of the surrounding area, the Thoroughfare Plan and the recommendation of the City Engineer. Rights-of-way, pavement widths and street grades shall be as specified in Appendix A, which is hereby made a part of this Ordinance.
(c) Alignment.
(1) In order to provide for efficient and effective access by emergency vehicles, the street pattern shall make provision for the continuance of streets and for the connection to existing rights-of-way in adjacent areas.
(2) If a subdivision adjoins or contains an existing or proposed arterial or major collector street, direct access points to such street shall be minimized. The Planning Commission may require marginal access streets or reverse frontage with a planting strip of a minimum width of twenty (20) feet on the rear of those lots abutting the said arterial or collector street, and no vehicular access across the strip.
(3) If a subdivision adjoins an existing or proposed arterial or major collector street, the Planning Commission may require drainage improvements and the construction of separate turn lanes and/or traffic signals on such streets into the proposed subdivision.
(4) Local streets shall be laid out so as to discourage use by through traffic.
(5) Streets shall intersect one another at ninety (90) degrees, or as near to ninety (90) degrees as possible, but in no case less than seventy-five (75) degrees.
