PLANNED UNIT DEVELOPMENT. An area of land, zoned under § 153.056, in which a variety of housing types and/or related commercial and industrial facilities are clustered in an imaginative preplanned fashion to permit the development of the land in an orderly, coordinated and comprehensive manner by preserving the natural quality and beauty of the land and providing a more livable housing environment. To foster creative planning, more flexible standards for streets, drainage, setbacks, lot sizes, etc. are provided within these subdivision regulations that are designed to meet the kinds of design conditions that exist within PUD's and which are examined and reviewed with §§ 153.050 through 153.058. The planned unit development is for the purpose of conserving land through more efficient allocation of private lots, multi-family dwelling units, common grounds and nonresidential uses, promoting greater efficiency in providing public and utility services, and securing the benefits of new techniques of community development and renewal. Within a planned unit residential development district or zone, the Zoning Ordinance regulations need not be uniform, but may vary in order to promote the public health, safety and morals, and the other purposes, as specifically identified in the Neighborhood Design Guidelines and other related documents. Adopted regulations may require developers to obtain conditional or final certification of compliance with the zoning ordinance at specified stages of development. As used herein, PLANNED UNIT DEVELOPMENT means a development which is planned to integrate residential use with collateral uses, and in which lot size, set-back lines, yard areas and dwelling types may be varied and modified to achieve particular design objectives and make provision for open spaces, common areas, utilities, public improvements and collateral nonresidential uses.
PLAT. A map of a tract or parcel of land made by a licensed land surveyor.

(2) PEAK RATE OF RUNOFF. The maximum rate of runoff for any storm.
(3) RUNOFF VOLUME. The total quantity or volume of runoff during a specified time period. It may be expressed in acre-feet, in inches-depth of the drainage area, or in other units of volume.
SIDEWALK. A paved area intended principally for use of pedestrians.
STORAGE. The control, retention or detention of runoff.
(1) DETENTION STORAGE. Storm runoff collected and stored for a short period of time and then released at a controlled rate (dry pond).
(2) RETENTION STORAGE. Storm runoff collected and stored for a short period of time and which is released at a controlled rate leaving in the facility a minimum pool of water. This facility is often associated with water-related recreational or aesthetic uses (wet pond).
STORAGE FACILITY. Any facility used to store, retain or detain storm runoff, which shall include but not be limited to retention and detention storage facilities, rooftop or parking lot ponds, basins, depressions and pools.
STORM DRAINAGE SYSTEM. The surface and subsurface system for the removal of water from the land, including both the natural elements of streams, gullies, ravines, marshes, swales and ponds, whether of an intermittent or continuous nature, and man-made elements which include conduits, and appurtenant features, culverts, ditches, channels, storage facilities, streets and the storm sewer system.
(1) INITIAL DRAINAGE SYSTEM. That part of the storm drainage system which is used regularly for collecting, transporting and disposing of storm runoff, snow melt, and miscellaneous minor flows. The capacity of the initial drainage system should be equal to the maximum rate of runoff to be expected from a designated storm which may have a frequency of occurrence of once in five years. The initial system is also termed the “convenience system,” “minor system” or the “storm sewer system,” and may include features ranging from curbs and gutters to storm sewer pipes and open drainage ways.
(2) MAJOR DRAINAGE SYSTEM. That storm drainage system which carries the runoff from a storm having a frequency of occurrence of once in 100 years. The major system will function whether or not improvements are situated wisely in respect to it. The major system is also termed the “emergency flow way.” The major system usually includes many features such as streets, ravines and major drainage channels. Storm sewer systems may reduce the flow in many parts of the major system by storing and transporting water underground.

(7) PRIVATE STREET. A strip of privately owned land providing access to abutting properties. Private streets shall be so indicated on the plat. Improvements of private streets shall conform to the minimum street standards and street sections as contained herein. In PUD zoned areas, private driveways and parking areas within commercial, industrial and multi-family areas shall not be construed to mean private streets.
(8) SERVICE ROAD. A street parallel with a limited access highway to afford abutting property owners access to such highway at permitted points, the use of which is subject to Planning and Zoning Commission approval.
SUBDIVISION. The division of any parcel of land shown as a unit or as contiguous units on the last preceding tax roll, into two or more parcels, sites or lots, any one of which is less than five acres for the purpose, whether immediate or future of transfer of ownership, provided, however, that the division or partition of land into parcels of more than five acres not involving any new streets or easements of access, and the sale or exchange of parcels between adjoining lot owners, where such sale or exchange does not create additional building sites and where the lots resulting are not reduced below minimum sizes required by law, shall be exempted; or the improvement of one or more parcels of land for residential, commercial or industrial structures or groups of structures involving the division or allocation of land for the opening, widening or extension of any street or streets, except private streets serving industrial structures; the division or allocation of land as open spaces for common use by owners, occupants or leaseholders or as easements for the extension and maintenance of public sewer, water, storm drainage or other public facilities.
