Section 47-6.01A. Use if optional proprietary earth retaining systems are allowed for any of the following:

1. Mechanically stabilized embankment (MSE) system

2. Type 1–5 retaining walls

3. Crib walls

Add to section 47-6.01A:

1. If there are different options at more than one location within a project, list each location separately. If both of the tables below are used, replace “table” with “tables.”

The alternative earth retaining system must be one of the systems shown in the following table:

2. Listed in the table below are the earth retaining systems with contact information for companies for which standard plans have been pre-approved. Design must specify which system is applicable for each job based on the criteria below and differential settlement requirements for each wall location in the project. Delete the systems that are not allowed from the table below. Design service life is 50 years.

The following are instructions for when each system listed in the table is allowed:

Reinforced Earth (5 ft cruciform concrete face panel) is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture .

Reinforced Earth (5 ft square concrete face panel) is an alternative to an MSE regardless of architectural treatment.

Retained Earth (5 ft square concrete face panel) is an alternative to an MSE regardless of architectural treatment.

MSE Plus (5 ft square concrete face panel) is an alternative to an MSE regardless of architectural treatment.

MSE Plus (5 ft high by 6 ft wide concrete face panel) is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture.

Welded Wire Wall is an alternative to a wire faced MSE.

Criblock is an alternative to a Standard Plan Crib Retaining Wall.

Port-O-Wall is an alternative to a Standard Plan Type 1 Retaining Wall when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture.

Tensar ARES system is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture, the anticipated total settlement is less than 8", and the anticipated differential settlement at any location along the wall length is less than 0.5 percent.

Landmark (modular block faced) is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture, and there is space to accommodate a 4 degree face batter.

KeySystem (modular block faced) is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture.

Verdura Segmental Retaining Wall System is an alternative to a Standard Plan Crib Retaining Wall or an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture, and there is space to accommodate a 14 degree face batter.

Mesa Retaining Wall System is an alternative to an MSE when there is no architectural treatment or the architectural treatment is a nonpictorial concrete surface texture.

Note: A pictorial is a formed relief texture depicting birds, flowers, county seals, etc.
