Proposed street improvements within the City shall conform to the pattern as established in the Major Street Plan as adopted by the City of Gardner. This states, on a general basis, that the thoroughfare classification of streets shall be constructed on section line roads at one-mile intervals and collector classification of streets shall be spaced at approximate midway locations between thoroughfares. Street improvements and public infrastructure shall be designed to conform to applicable codes, regulations, ordinances, and the “Technical Specifications for Public Improvement Projects, City of Gardner, Kansas” (Technical Specifications), as established by the City of Gardner.

1. Local Streets. A “local street” shall mean a street that is primarily used to provide access to abutting residential property.
2. Collector/Service Streets. A “collector street” shall mean a street which in addition to serving abutting residential property, intercepts residential streets, carries neighborhood traffic to major arterial street system, and connects with community facilities. The number of lots fronting collector streets should be held to a minimum.
3. Arterial Thoroughfare Streets. An “arterial thoroughfare street” shall mean a street of considerable continuity which serves or is intended to serve as the principal traffic way between separated areas or districts.
C. Street Design Standards. All streets shall conform to the requirements of the Technical Specifications, latest edition. All variances must be approved by the City Engineer.

D. Maximum Gradient. The maximum gradient for streets as noted in subsection (C) of this section may be exceeded only upon written approval of the City Administrator after recommendation by the City Engineer. Such approval will only be granted in unusual cases where grades within the acceptable limits cannot be obtained.
E. Off-Center Street Intersections. Off-center street intersections shall be separated by a minimum centerline dimension of 150 feet.

All storm drainage works shall be designed in accordance with American Public Works Association Section 5600 Storm Drainage Systems and Facilities (APWA), which was approved by the Kansas City Metropolitan Chapter of APWA in December 2005 and formally adopted by the Executive Board on February 15, 2006.
1. The City Engineer is authorized to adopt any revisions to APWA Section 5600 approved by the Kansas City Metropolitan Chapter of APWA and its Board or may adopt additional revisions to APWA Section 5600 that are based on sound engineering principles. The City Engineer shall file any revisions so adopted with the City Clerk.

3. The following paragraph is added to the end of APWA 5601.5 A 4:
If there are no existing flooding problems and flooding problems will not occur as a result of the proposed development as documented by a stormwater management plan approved by the City Engineer, runoff from the development shall be controlled by limiting the stormwater release rate for the ten percent (10%) and one hundred percent (100%) storm to the predevelopment peak flow rates for the ten percent (10%) and one hundred percent (100%) storms, respectively.
4. A stormwater management plan must be submitted for each development. A preliminary stormwater management plan must be provided with submittal of the preliminary plat, site plan, or the preliminary or final development plan for a planned zoning district, and a final stormwater management plan must be submitted to and approved by the City Engineer prior to issuance of building permits. The stormwater management plan shall be prepared by a licensed professional engineer in the State of Kansas and shall contain such information including, but not limited to, maps and diagrams, design data and calculations, plans and detailed drawings, and specifications prepared in accordance with APWA 5600 and applicable local, state, and federal regulations.
G. Cul-de-Sacs. At locations where streets are to be terminated and a vehicular connection between adjacent streets is not required, a cul-de-sac may be permitted. Such a cul-de-sac shall be constructed with a minimum radius of 39 feet to the back of the curb and shall not exceed 800 feet in length.
H. Temporary Turnarounds. At locations where streets are to be temporarily terminated which will be extended at a later date, and said street extends beyond the intersection of an adjacent street more than three lots, a temporary cul-de-sac shall be constructed with a minimum radius of 35 feet.
