12.08.040 Road base and blacktop.
The base of all roads shall be constructed in the center of all rights-of-way. Such base shall be composed of such material and of such thickness as shall be recommended by an engineering analysis of the character of the soil and contemplated traffic, and said base shall be covered with a penetrating coat of oil and surfaced by a coat of blacktop at least two inches in thickness unless written permission for a modification of these specifications is obtained from the board upon the recommendation of the county road commissioner. All materials used in such construction shall be approved in writing by the road commissioner prior to their use. (Ord. 303 §1(2), 1959).
12.08.050 Mains and pipes--Intersections.
All water mains, sewer pipes, drainage systems and pipes employed for any other purposes shall be buried at least eighteen inches below the surface and shall be located a reasonable distance from the paved or traveled portion of all rights-of-way, and all road intersections shall be at right angles, or as nearly so as practicable. (Ord. 303 §1(3), 1959).
12.08.060 Gutters and drains.
All gutters and drains, including head walls, drop inlets and covers shall be constructed and installed according to the size and specifications required by the county road commissioner. (Ord. 303 §1(4), 1959).
12.08.070 Removal of obstructions.
No structures or buildings shall be constructed within twenty-five feet of the nearest right-of-way line, and all trees, shrubbery or other obstructions interfering with vision or with the construction or maintenance of any right-of-way shall be removed prior to the submission of any road for acceptance. (Ord. 303 §1(5), 1959).
12.08.082 Requirement that new county roads be maintained
through a county service area.
A. Prior to any road’s being accepted by the board of supervisors into the county road system as a county highway, the road and parcels benefitted thereby may be included in a county service area providing annual maintenance revenue from charges imposed on each parcel therein in accordance with the provisions of Government Code 25210.77a, so that the costs of maintaining said road are borne by the parcels included in the county service area.
B. The charges may be determined by apportioning the total cost of the maintenance of said road to each parcel in said county service area in proportion to the estimated benefit from said road to be received by each parcel. However, said annual charges shall result in no less than five thousand dollars per mile of said road with said amount inflated or deflated annually in accordance with the Consumer Price Index with 1989 being the base year. The revenue from said charges, less auditing and other administration costs incurred for said county service area, shall be used only for the maintenance of said road. If in any fiscal year revenue from charges raised in the county service area for said road exceeds the cost of maintaining said road, the excess funds shall be retained and used only for the future maintenance of said roads in said county service area.
C. The board shall annually fix and collect the charges as set forth in this chapter. (Ord. 1612 §2 (part), 2005; Ord. 1194 §6, 1989).
12.08.084 Drainage improvements, driveway approaches, postal
service encroachments, and other appurtenances required.
As a condition to any road’s being accepted by the board of supervisors into the county road system as a county highway,.said board shall make a finding that said road has adequate drainage improvements, driveway approaches, postal service encroachments, and other appurtenances necessary to protect said road. Compliance with said requirements shall be determined by the board of supervisors or its designee. (Ord. 1194 §7, 1989).
12.08.086 Procedure for establishing and collecting charges
for roads in county service areas.
A. Once a year the board of supervisors shall cause to be prepared a written report which shall contain a description of each parcel of real property receiving county highway maintenance in the county service area and the amount of the charge for each parcel for such year computed in conformity with the procedure set forth in this chapter. Such report shall be filed with the clerk of the board of supervisors.
B. Upon the filing of such report, the clerk shall fix a time, date, and place for hearing thereon and for filing objections or protests thereto. The clerk shall publish notice of such hearing as provided in Government Code 6066 prior to the date set for hearing.
C. At the time, date, and place stated in the notice, the board of supervisors shall hear and consider all objections or protests, if any, to the report and may continue the hearing from time to time. Upon conclusion of the hearing, the board of supervisors may adopt, revise, change, reduce, or modify any charge and shall make its determination upon each charge as described in the report and thereafter, by resolution, shall confirm the report.
D. The charges set forth in the report, as confirmed, shall appear as a separate item on the tax bill. The charge shall be collected at the same time and in the same manner as ordinary county ad valorem property taxes are collected and shall be subject to the same penalties and the same procedure and sale in case of delinquency as provided for such taxes. All laws applicable to the levy, collection, and enforcement of county ad valorem property taxes shall be applicable to such charge; except that, if for the first year such charge is levied the real property to which such charge relates has been transferred or conveyed to a bona fide purchaser for value, or if a lien of a bona fide encumbrancer for value has been created and attaches thereon, prior to the date on which the first installment of such taxes would become delinquent, the charge confirmed pursuant to this section shall not result in a lien against such real property but instead shall be transferred to the unsecured roll for collection.
E. Whenever a railroad, gas, water or electric utility right-of-way or electric line right-of-way is included within such service area, or zone thereof, the railroad, gas, water or electric utility right-of-way or electric line right-of-way shall be subject to the charges authorized only if, and to the extent that, it is found that it will benefit from the particular extended service, and the railroad, gas, water or electric utility right-of-way or electric line right-of-way shall be subject to the same penalties, and the same procedure and sale, in case of delinquency as other properties in such service area or zone. In determining whether or not the railroad, gas, water or electric utility right-of-way or electric line right-of-way benefits from the extended service, its use as a right-of-way for a railroad, gas, water or electric utility shall be presumed to be permanent. (Ord. 1194 §8, 1989).
For statutory provisions relating to the acceptance by counties of roads into the county highway system, see Strs. & Hys. Code §941.
