Standards design for residential subdivisions shall utilize gray fiberglass poles anchored in underground sleeves and gray cobra head LED luminaires producing an IES Type 11 or Type III cutoff pattern. 3. The Design Engineer shall consult with the City to determine which lighting design is appropriate for the roadway under design. 4. Standard design for arterial and collector streets shall include the following: a. Arms and LED luminaires installed on existing utility company poles; or b. Gray fiberglass poles anchored in underground sleeves and gray cobra head LED luminaires producing and IES Type II of Type III cutoff pattern; or c. Steel Hot Dipped galvanized poles with concrete foundations and gray cobra head LED luminaires producing an IES Type II or Type III cutoff pattern. 5.

The design may include a mixture of pedestrian scale lighting and standard street lighting. 6. The lighting design analysis for arterial, collector, commercial and industrial streets shall be in the form of computerized output from an industry -accepted lighting package that includes calculated IES luminance levels, maximum -to -minimum uniformity ratio, average -to -minimum uniformity ration, design fixture, input wattage, light mounting height, light spacing, along with a plan view of the isocandela lighting distribution. Minimum maintained average luminance levels, maximum -to - minimum uniformity ratio, and average -to -minimum uniformity ratio shall be per the following maintained luminance table.
