98 Section 12.4.1 Curb Installation requirements

B.    Alternative curb systems, such as no-elevation curb, curb openings, flat curb, and other alternative systems, may be allowed in place of standard curb and gutter systems as described in Section 12.4.1, subject to: a. Stormwater control measures shown on the stormwater control master plan for a new development or expansion of existing development must control stormwater on a runoff volume basis in accordance with UDO Section 9.2.2.B.1.c.; and b. Approval by the Engineering Services Director or a designee after considering situation-specific factors including, but not necessarily limited to, pedestrian safety, vehicular safety, historic preservation, streetscape aesthetics, and management of stormwater collection and conveyance outside the Travelway without resulting in soil erosion or otherwise impacting the integrity of the drainage system. A.    The use of GSI practices for managing stormwater within the right-of-way is encouraged. GSI practices typically are installed behind the curb either outside of the Travelway or in a median or curb bump-out. Figure 5 shows example placement of GSI devices and additional information for several GSI practices that can be found in the City of Raleigh Standard Details .
