(A) A two foot concrete curb and gutter shall be required for all residential subdivision streets. Streets with a design speed of 45 mph or less shall have the option of using either a mountable or barrier curb. Streets with a design sped greater than 45 mph should be designed without curbs. However, if necessary, a four inch mountable curb may be used.
(B) Materials, concrete specifications and construction procedure shall comply with Section 605 of the Standard Specifications.
(C) To prevent undermining by water, curbs shall be promptly and carefully backfilled after application of curing protection, which shall take place immediately after slipforming or removal of forms. Backfill shall be compacted as soon as practical and maintained at an elevation slightly below the curb. As the backfill settles, it shall be regraded as often as necessary to keep it slightly below the curbs.
(D) Valley gutters which connect gutter drains across street intersections are strictly prohibited.
