(§ 1, Ord. 87-662, eff. June 4, 1987; as amended by § 1, Ord. 96-874, eff. December 5, 1996, § 3, Ord. 041014, adopted August 17, 2004; and §§ III—V, Ord. 06-1046, adopted May 2, 2006; § 1(Exh. A), Ord. 20181114, adopted October 9, 2018)

Sec. 9-4.607. - Improvements to existing roads.

(a)

All developments directly benefited by a precise planned road, other than a major thoroughfare, must:

(1)

Dedicate rights-of-way on-site as necessary to conform to the appropriate standard; and

(2)

Pay into the County Road Fund a sum of money equal to the prorated share of the benefit received by the road; or

(3)

Construct a portion or all of the road; or

(4)

A combination of subsections (2) and (3) of this subsection.

(b)

The prorated share of the benefit received by the road shall be calculated in one of the following ways:

(1)

The prorated share shall equal the predicted traffic volume on the road arising from the development, divided by the projected traffic volume for the road, and multiplied by the cost of the improvement of the road to the standards for its class, as set forth in Article 5 of this chapter.

(2)

The prorated share shall equal the predicted traffic volume on the road arising from the development, divided by the existing traffic volume for the road, and multiplied by the cost of the improvement of the road to the minimum standards for its class, as set forth in Article 5 of this chapter.

(3)

The prorated share for development in Commercial, Industrial, or Recreation Areas shall equal the acreage of the development, divided by the Commercial, Industrial, and Recreation Area acreage served by the road, multiplied by the cost of the improvement of the road to the minimum standards for its class, as set forth in Article 5 of this chapter, after the cost of improving the road to the minimum standards for the class it would be if it did not serve any Commercial, Industrial, or Recreation Area is subtracted from the cost of improving the road to the minimum standards for its class. This hypothetical classification shall be based upon the projected traffic volume for the road and the provisions of Article 4 of this chapter.

(4)

The prorated share shall equal the predicted traffic volume on the road arising from the development, divided by the projected traffic volume for the road, and multiplied by the cost of the improvement of the road to the minimum standards for its class, as set forth in Article 5 of this chapter, based upon a specific traffic analysis for the development and roads in the area.

(c)

The method used to calculate the prorated share of the benefit received by a road shall be determined by the person or body approving the development. The Director of Public Works shall recommend the method to be used to calculate the prorated share of the benefit received by a road and shall calculate that share.

(d)

The cost of improvement shall be based on a cost estimate prepared by the developer's engineer and mutually agreed upon the developer and the Director of Public Works. The cost estimate shall be provided with the project application.

(e)

Predicted traffic volume, projected traffic volume and the Commercial, Industrial and Recreation Area acreage served by a road shall be determined as set forth in Article 7 of this chapter.

(f)

In the event the developer's prorated share exceeds fifty (50%) percent of the total cost of improvement, the required improvements shall be completed for the subject portion of the road.

(g)

It shall be the County's prerogative that whenever any work on an existing County road is to be partially financed by the County, the County may elect to do the work with its own forces. Otherwise the improvement work within a development shall be done by the developer's contractor.

(h)

All developments directly benefited by a private road shall make whatever improvements are necessary to bring the road into conformance with the class necessary to serve such developments.

Article 7. - TRAFFIC VOLUME

Sec. 9-4.701. - Traffic volume.

Traffic volume shall be expressed in ADT (Average Daily Traffic).

(§ 1, Ord. 87-662, eff. June 4, 1987; § 1(Exh. A), Ord. 2018-1114, adopted October 9, 2018)

Sec. 9-4.702. - Existing traffic volume.

The existing traffic volume for a road shall be the higher of the actual summer ADT and the estimated winter ADT.

(§ 1, Ord. 87-662, eff. June 4, 1987; § 1(Exh. A), Ord. 2018-1114, adopted October 9, 2018)

Sec. 9-4.703. - Projected traffic volume.

The projected traffic volume for a road shall be:

(a)

Based on the maximum potential number of dwelling units served by that road based on the planned density of development of the areas to be served as determined by the General Plan designation of areas to be served. The projected traffic volume from areas to be served shall be calculated as follows:

(1)

The maximum potential number of dwelling units within two (2) road miles of a United States Post Office shall be multiplied by eight (8).

(2)

The maximum potential number of dwelling units between two (2) and four (4) road miles of a United States Post Office shall be multiplied by five (5).

(3)

The maximum potential number of dwelling units more than four (4) road miles from a United States Post Office shall be multiplied by two (2).

(4)

The figures resulting from the above procedure shall be added and shall be the projected traffic volume for the road in ADT.

(b)

The predicted traffic volume arising from a development shall be calculated as follows:

(1)

If any portion of development is within two (2) road miles of a United States Post Office, the traffic volume arising from the development equals the proposed number of lots or dwelling units times eight (8).

(2)

If all of the development is more than two (2) road miles from a United States Office and if any portion of the development is within four (4) road miles of a United States Post Office, the traffic volume arising from the development equals the proposed number of lots or dwelling units times five (5).

(3)

If all of the development is more than four (4) road miles from a United States Post Office, the traffic volume arising from the development equals the proposed number of lots or dwelling units times two (2).

(4)

The figures resulting from the above procedure shall be the predicted traffic volume arising from the development in ADT.

(c)

The projected traffic volumes calculated by the above methods may be adjusted in specific cases where actual traffic count or analyses or both of comparable traffic situations yield alternative values.
