Section 11.2.4 Sidewalk Access Ramps Sidewalk access ramps shall be provided at all intersections where curb and gutter are provided and where sidewalks and/or greenway trails intersect any street. Sidewalk access ramps shall be constructed per City of Raleigh Standard Details (See transportation Details T-20.01.1 through 20.04.5) and/or current Public Right of Way Advisory Group (PROWAG) standards. Section 11.2.5 Planting Area The following can be found in Articles 7.2 , 8.4 , and 8.5 of the UDO. Tree Planting A.

Unless otherwise noted below, all trees planted in accordance with Article 8.2 of the UDO must be shade trees. C. Where overhead utilities exist, 1 understory tree shall be planted every 20 feet on center, on average. Required understory trees may be installed within GSI practices. Up to 20% of required understory trees may be offset by installing vegetated GSI practices, such as stormwater planter boxes. A maintenance plan must be approved for the GSI practice according to Section 9.2.2.D. D. All required street trees must meet the design and installation requirements of Section 7.2.7 of the UDO . If a GSI practice is part of an approved stormwater management plan for the site, required street trees may be installed within the GSI practice. A maintenance plan must be approved for the GSI practice according to Section 9.2.2.D. Planting for Development Abutting NCDOT Streets A. Where development abuts a street controlled by the North Carolina Department of Transportation as shown on the Raleigh Powell Bill Map , street trees may not be required in the right-of-way, at the discretion of the North Carolina Department of Transportation. In this instance, a Type C2 street protective yard is required in accordance with Section 7.2.4 of the UDO . See the Guidelines for Planting within Highway Right-of-Way on NCDOT maintained roads for guidance. B. Unless otherwise noted below, all trees planted in accordance with this Article must be shade trees. C. In accordance with Section 7.2.4.B.4. of the UDO, GSI practices shall be allowed in Street Protective Yard Type C2. In order to accommodate GSI practices, the number of shrubs may be reduced in these protective yards by ten (10) percent. D. In accordance with UDO Section 7.2.7.C.4.a., in protective yards, 50% of required trees shall be locally-adaptive evergreen species, except where an approved GSI practice is in a protective yard. E. In accordance with UDO Section 7.2.7.C.5.b.vi., to accommodate multi-functional GSI practices as part of an approved stormwater management plan, the number of shrubs may be reduced in Protective Yards by 10%, non-evergreen species may be used in lieu of up to 35% evergreen shrubs, and all shrubs may be 24 inches when planted.
