ST MARK MAYFAIRE ENTRANCE [TRC Plan Rev #3]
ROUNDABOUT DESIGN:
• At cut-through pedestrian refuge islands, detectable warning surfaces shall begin at the curb line and extend into the cut-through area. It must not protrude into the gutter section.
• Based on dimensions, it seems that cut-through pedestrian refuge islands are less than 6 ft in length. If it is so, than detectable warning domes are not required and shall not be installed. Thus allowing pedestrians to cross the street in one stage.
• Please include the details for ‘UM’ (for yield lines) in the Pavement marking schedule.
• End of roadway object markers/signage must be installed at the end of ‘Road D’ stub [MUTCD].
• Reconcile the central island diameter on the geometric plan, summary table and cross section details.
STREET LIGHTING [City of Wilmington Street Lighting Policy]:
1. Please verify the minimum number of standard street lights required for this sub-division on the site plan (Street lighting notes on sheet C-2.2). The standard street lights required and plotted on the plan are five but seven is populated in the notes (Plan is provided with the previous review).
Please let me know if you have any questions or if I can be of further assistance as this development moves through the review process.
ST MARK MAYFAIRE ENTRANCE [TRC Plan Review# 5]
TECHNICAL STANDARDS – NEW ROADS:
1. Please provide standard street names for the proposed project. Additionally, please verify with City of Wilmington GIS Addressing, whether the Roundabout section, Road B, requires a separate street name.
TECHNICAL STANDARDS – ACCESS (driveway, sidewalk, and sight distance):
2. The sidewalk beside Road C and adjacent to CI-16 has an exit ramp, however, it does not have a receiving ramp on the opposite side of the landscape island.
TECHNICAL STANDARDS – Barrier Free Design:
3. The proposed connections from the Roundabout to the multi-use path must meet slope and cross slope for a pedestrian route.
4. If the elevation of the crosswalk and proposed multi-use path have less than the 5% slope and 2% cross slope, it may be possible to maintained an at grade connection with a curb cut.
Please let me know if you have any questions or if I can be of further assistance as this development moves through the review process.
