Sec. 110-53. Minimum standards for street classifications, street geometrics and right-of-way widths, soil classifications and pavement sections.
The proposed street classifications, street geometrics and right-of-way widths, soils classifications and pavement sections shall equal the following minimum standards and requirements:
(1) Street classifications by traffic and 18-kip EALs*: These street classifications should not be confused with the functional classifications of the master street plan. Each street shall be classified by function and/or traffic in one of the following classes subject to approval by the planning and community development director or his/her designated representative:
a. Class I. Residential drives including short drives, short dead-end streets, or short cross streets.
1. 0--50 vehicles per day.
2. Maximum of five average 18-kip EALs per day.
3. Maximum of 36,500 total 18-kip EALs in 20-year design period.
b. Class II. Light residential, light commercial and minor residential collector streets including:
1. Residential subdivision streets with no through traffic.
2. Cross streets in the established street system.
3. Light commercial streets in a small commercial area.
i. 50--150 vehicles per day.
ii. Maximum of ten average 18-kip EALs per day.
iii. Maximum of 73,000 total 18-kip EALs in 20-year design period.
------------
Note--EALS fOR class I and II streets based on 100 percent of the one-way ADT times a load factor of 0.09 for single-unit trucks, plus five percent of the one-way ADT times a load factor of 1.00 for multiple-unit trucks. EALs for class III and IV streets based on 100 percent of the one-way ADT times a load factor of 0.09 for single-unit trucks, plus ten percent of the one-way ADT times a load factor of 1.00 for multiple-unit trucks.
------------
c. Class III. Residential collector and commercial streets including:
1. Major streets in a residential subdivision used for access to a through street or highway (collectors will have the right-of-way to class I and II streets above).
2. Commercial streets.
i. 150--400 vehicles per day.
ii. Maximum of 40 average 18-kip EALs per day.
iii. Maximum of 292,000 total 18-kip EALs in 20-year design period.
d. Class IV. Minor residential arterial, heavy commercial, and light industrial streets including:
1. Through streets in a residential subdivision; heavy commercial streets.
2. Light industrial streets in a small industrial area with little or no adjacent area for expansion.
i. 400--850 vehicles per day.
ii. Maximum of 80 average 18-kip EALs per day.
iii. Maximum of 584,000 total 18-kip EALs in 20-year design period.
e. Class V. All higher class streets (formal design procedures shall be used):
1. Minimum of 850 vehicles per day.
2. Maximum of 80 average 18-kip EALs per day.
3. Maximum of 584,000 total 18-kip EALs in 20-year design period.
(2) Street geometrics and right-of-way widths:
a. All proposed street widths and right-of-way widths shall meet or exceed the minimum widths shown on the adopted master street plan.
b. All intersection approaches shall have adequate horizontal and vertical sight distance as defined by the design speed outlined on the master street plan.
c. At intersections, the radius to the face of the curb shall meet the minimum outlined on the master street plan or as determined by the director of planning and community development or his/her designated representative based on anticipated traffic composition.
(3) Pavement sections:
a. For street classifications I--IV. Pavement section for city streets shall be designed as follows:
1. Determine the street classification as outlined previously in this section.
2. Classify the subgrade soil according to the AASHTO Soil Classification System.
3. Refer to "minimum pavement section by street and soil classification" on page "A8" of the City of Springdale, Arkansas Standard Details for Street and Drainage Construction to determine the required structural number and suggested pavement sections.
b. For street classification V, a formal design by a registered professional engineer in the State of Arkansas based on projected traffic loads for a 20-year design period shall be required.
