(A) Road specifications must meet the standards of the public road jurisdiction. Approach permits must be obtained by the subdivider from the public road jurisdiction. The public road jurisdiction may require additional road work be done by the subdivider upon adjoining roads that are impacted by a large scale development (e.g., requiring a left hand turn lane) if required for traffic safety and the reasonable maintenance of the road.
(B) If the public road jurisdiction is the county’s Road and Bridge Department, the following road standards must be met: Idaho Local Highway Technical Assistance Council (LHTAC) standards shall be used in the design and construction, except:
(1) Plant mix pavement is not required by this chapter. Two inches of top course of one inch minus crushed rock material may be substituted for the plant mix pavement, and this in addition to the four inches of base material, where the owner, developer, and engineer have assumed liability for quality control and assurance of the final product;
(2) Gradation and compaction of sub-base or ballast may be modified where the owner, developer, and engineer have assumed liability for quality control and assurance of the final product; and
(3) Compaction of subgrade may be modified where the owner, developer, and engineer have assumed liability for quality control and assurance of the final product.
