a. All streets shall include curbs on both sides except in the situations of interim width improvements. The minimum tangent curb gradients shall be as outlined under Section 2.16, 'Vertical Alignment'.
b. The standard curb for City Streets shall be Type A curb and gutter for all road classifications.
1) Use of Type C curbs requires written approval by the City Engineer for each location proposed, and is typically limited to replacement of short lengths of existing Type C curbs (other than at new driveway approaches), use at raised pedestrian crossing islands, or where required by County or ODOT standards.
2) Where Type A curb and gutter is installed along the edge of existing paved streets the pavement shall be saw cut at the edge of the gutter pan and the new curb & gutter placed against the saw cut, in order to minimize the need for street patching and repaving.
c. The ends of all curbs shall be tapered downward to prevent damage to vehicle tires.
d. A six (6) inch curb exposure is normally required on residential streets and streets with curb and gutter. A eight (8) inch exposure may be required by the City Engineer on streets where Type C curbs are allowed. Greater curb exposure shall also be provided where required by ODOT standards.
e. Alternate curb sections will be considered per section 1.11 variances to Design Standards.
f. A stamp shall be placed to mark where each water, sanitary sewer, or storm drain service lateral crosses the curbline when new curbing is being placed. The curbs shall be marked on the top of the curbs with an imprinting stamp a minimum of 2-inches high. The impression for a water service shall be the letter "W". The impression for a sanitary sewer service shall be the letter "S". The impression for a storm drain service shall be the letter "D".
