County Engineer Leonazd Odom, Jr. Road Administrator Truby Hardin, Coordinator Kerr County Road & Bridge 4010 San Antonio Hwy Kerrville, Texas 78028 MEMO TO: FROM: DATE: COMMISSIONERS COURT FRANKLIN JOI-iN5TON, P.E., KERB COUNTY ENGINEER May 20, 2003 Telephone: 830-257-2993 FAX: 830-896-8481 Email: kcroads@ktc.com RE: Consider clarifying the definition of "road" as discussed in Section 1.02.C, same as "road" in Section II and Section VII. In some cases, the definition of "road" (street, alley, etc.) in Section 1.02. C. determines whether a tract of land is subject to Kerr County Subdivision Rules. Roads are defined in Kerr County Subdivision Rules in Section II and Section VII. Detailed definitions of different types of roads are shown in Section 7.06.14, Page 36-38. Many definitions have been used in the past concerning Section 1.02.C. but I think we can all agree that when a person purchases a subdivided tract of land, or a lot, that the intent of Section 7.06.14 is to provide them an adequate road for access to their lot; provided access for police, fire trucks and ambulances; and a road the County will not have to build to subsidize the developer. In light of the above, I would suggest that Section 1.02.C. means: 1) a state highway, 2) a county maintained road, or 3) a public or private road built to the standards of Section 7.06.14 of the Kerr County Subdivision Rules 7.06. I 1 Curbed Streets: Where streets or roads are proposed to be provided with curbs or curbs and gutters, design and construction details shall be in conformity with the specifications in 7.06.14. (See Appendix K) 7.06.12 Shoulders: Untreated shoulders shall be bladed and dragged for uniformity after placement of the surface and shall be smooth, stable and well compacted for the entire width. The thickness of base shall not vary from the prescribed thickness by more than one-half ('/z} inch at any point tested. 7.06.13 Cattle Guards: The Commissioners Court will authorize the installation of cattle guards when considered appropriate for public safety. When permitted, a cattle guard shall be not less than six (6) feet in width, measured along the center of the road and of a length not less than one (1) foot greater than the width of the pavement or twenty (20) feet, whichever is greater. (a) Deck Members: Deck members shall be either weldable upset carbon steel tubing two and three eighths (2-3/8) inches outside diameter or relayed rails weighing not less than seventy (70) pounds per yard. (b} Support Members: Support members shall be structural steel shapes of size and section adequate for H-15 loading with twenty-five (25) percent impact allowance. Support sections shall be spaced not more than thirty- one (31) inches for tubing decks or forty-eight (48) inches for rail decks. - Units may be prefabricated or welded in place, provided fastenings to masonry foundation are arranged for ready removal for clean out. Supporting masonry shall extend to firm foundation or shall be designed as an open flume with ends closed except where structure serves as a drainage structure. Pit drainage shall be provided for closed end structures. 7.06.14 Typical Road Sections: The design parameters for the classifications of the roads herein as well as the ultimate design, pursuant to the road definitions contained herein, will be determined by the County Engineer and approved by the Commissioners Court. (a) Minimum Requirements: (1} Arterial Road: An "arterial road" serves a large area. It is a heavily traveled route connecting urban areas, and major traffic generators. Arterials are often divided into major and minor categories. (2) Collector Road: A "collector road" is a principal thoroughfare within a subdivision. It collects traffic from local roads and channels the traffic into the arterial system.
