2. At the corner of the approaching vehicle lane for all intersections with arterial streets.
3. At two (2) opposing corners of a four-way intersection of two (2) collector streets; or at the corner of the approaching vehicle lane of a collector street intersecting another collector street at a T-intersection.
B. Type III Lighting Units: Type III lighting units shall be installed:
1. Every six hundred sixty feet (660') along both sides of urban collector streets offset such that there is one streetlight approximately every three hundred thirty feet (330') on alternating sides of the collector street.
2. At two (2) opposing corners of a four-way intersection of two (2) local streets or a local street with a collector street; or at the corner of the approaching vehicle lane of a local street at a T-intersection with another local or collector street.
3. At the terminus end of a cul-de-sac street.
4. At the point of deflection in the alignment of a single curved street where the interior angle is one hundred thirty five degrees (135°) or less. The lighting unit is to be located on the interior of the curve unless a sidewalk exists on the outside of the curve, and then the lighting unit shall be located adjacent to the sidewalk.
C. Residential Street Lighting: Within residential subdivisions developed within the Sanitary Sewer Service District defined by the Comprehensive Plan, one type III lighting unit shall be installed:
