Roadway Design and Right of Way Standards DRAFT Dec14-17 for review only A system of design guidelines is an effective tool to help provide safe, efficient, and consistent roadway networks. Some situations may require additional analysis due to unusual or unforeseen conditions, but established baseline standards will minimize design uncertainties in most circumstances. This is not a purely technical issue, and individual communities may have different preferences for design standards. Table 8-12 represents recommended typical roadway cross-sections based upon each functional class. This table represents a range of traffic levels for each roadway functional class and the corresponding design requirements. Right of way standards for the various roadway categories are also presented in Table 8-12. It may be noted that the City prefers and supports an integrated transportation network, with good circulation properties and limited cul-de-sacs. The City also prefers efficient connectivity with neighboring communities.

(3) Cross-section and right-of-way width are not inclusive of intersection locations, when additional right-of-way and cross-section width may be necessary. TRANSPORTATION 188
