RE: Proposed Clarification of the Grades by Road Type Table in LUR CH 6.18 Date: December 21, 2022
There has been some confusion when reading the existing table found in Section 6.18 of the Land
Use Regulations. The County Engineer is proposing a clarification to the table. The table refers to grades and the related correct curve radius and shoulder requirements (see County Engineer Letter dated December 16, 2022 attached). The intent of the table is the following:
• Grades up to 6% will have a 20-foot travel way with 0 shoulders and a minimum curve
radius of 250 feet.
• Grades between 6% to 8% will have a 20-foot travel way with 1-foot shoulders and a minimum curve radius of 250 feet.
• Grades between 8% to 10% will have a 20-foot travel way with 2-foot shoulders with a
footnote at the bottom for grades up to 10%.
• The Maximum Length for 8-10% grade is no more than 500 feet straightaway with a 20 ft travel way with 2 ft. shoulders. This section should have a horizontal radius of 1,500 feet or greater, grades shall not exceed 6% for 500 feet on either end of the section, curves with a radius of less than 600 feet shall not be within 500 feet on either end of the
section. The revised table is shown below:

The revised table will clarify what is found in the existing table shown below:
The revised table provides for a clearer requirement for the Minimum Curve Radii, grades and
shoulder requirements for Road Types A, B and C. The revised table format has not changed the
content of the table. Because this change to the LUR is deemed as correcting a clerical error and is not contrary to the public interests, the BCC does not require a public hearing to make this correction.
Thank you.
