WOODLANDS AT ECHO FARMS TRACT 3A [TRC Plan Review #2]
NEW ROADS:
1. Please show the full centerline pavement markings for the proposed street.
2. A pedestrian crossing is shown connecting clubhouse and mail kiosk. Sight distance easements and the landscaping plan will be required to provide AASHTO safe stopping distance to the crosswalk.
3. A raised center median/pedestrian refuge with In-street Pedestrian Crossing Signs (R1-6) and Pedestrian Crossing (W11-2 and W16-7P) are recommended for this crosswalk as per MUTCD.
4. An enhanced advanced warning of the crossing for northbound traffic, in addition to the standard MUTCD signage will be required.
5. A handicap signage for a handicap space to the north of the clubhouse is shown within Midvale Dr ROW. Please relocate this sign outside the ROW.
6. In previous submittal, a mid-block crossing was proposed across Chastain Dr. If that crosswalk is planned to be installed along the future projects, all the relevant comments from previous review would be applicable.
ROUNDABOUT – Belfairs Dr Intersection:
7. Please show the approach sight distance, intersection sight distance and sight distance to crosswalk for this roundabout.
8. Dimension the stopping sight distances to crosswalk and show the design speed and sight distance relationship calculation.
9. A refuge island is shown at the Midvale Dr end of roundabout. 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.
10. If cut-through pedestrian refuge islands are less than 6 ft in length detectable warning domes are not required because detectable warning surfaces must extend 2 ft minimum on each side of the island and be separated by 2 ft minimum. Please verify these distances and provide the dimensions.
ROUNDABOUT – Midvale Dr and Chastain Dr:
11. Refuge islands are shown at this roundabout. 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.
12. If cut-through pedestrian refuge islands are less than 6 ft in length detectable warning domes are not required because detectable warning surfaces must extend 2 ft minimum on each side of the island and be separated by 2 ft minimum. Please verify these distances and provide the dimensions.
13. Dimension the stopping sight distances to crosswalk and show the design speed and sight distance relationship calculation.
14. If the central island is designed to be fully traversable, atleast one of the traffic sign shown within an island is in conflict with the left-turn movement of the designed vehicle (based on the Autoturn exhibit). Relocate the sign, if required.
15. Autoturn exhibit:
a) Please show the type of the fire truck and garbage truck used for the turning template.
b) Garbage truck is shown as acquiring more space while maneuvering over central mountable island, as compared to fire truck. Please verify and explain.
TECHNICAL STANDARDS – ACCESS (driveway, sidewalk, and sight distance):
16. Show and apply the City’s 20’x70’ sight distance triangle at the driveway off Chastian Dr roundabout.
TECHNICAL STANDARDS – Barrier Free Design:
17. Relocate the accessible parking sign in front of building #9, from accessible aisle to accessible space.
18. Handicap signs are shown at the incorrect place for the spaces in front of building #15. Please relocate in front of the handicap spaces.
STREET LIGHTING [City of Wilmington Street Lighting Policy]:
1. A layout for the Standard street lighting provided with the previous subdivision review is still applicable. Minimum of six street lights are required for this sub-division. Revise on the site plan as required. Although, developers may choose to provide any extra lights or ornamental. Any installations above the criteria of Standard street lighting, will be considered as non-standard and has to conform to the City’s non-standard street lighting procedure as per the policy.
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.
Engineering has reviewed the plans for the Woodlands Landing at Echo Farms-Tract 3A project submitted February 1, 2019 and offer the attached comments.
WOODLANDS AT ECHO TRACT 3A [TRC Plan Review #4]
Initial Review Note
All comments are based on adopted policy documents, specific City of Wilmington Land Development Code (CofW LDC) and City of Wilmington Technical Standards and Specifications Manual (CofWTSSM) requirements in effect at the time of this review. These have been noted after the comment as appropriate for your ease in further research.
The City Engineer may administratively approve dimensional variance requests per LDC Sec. 18-348. If the Applicant feels further interpretation is in order, please contact Transportation Planning directly to discuss in additional detail. Please apply for all administrative variances in writing, an email is acceptable or this may be included on the plan set. Please see Sec. 18-348 of the Land Development Code for the information required to process a variance request.
BASE INFORMATION:
• As previously stated, the project connects to the signalized intersection of Echo Farms Blvd and Carolina Beach Road. Show the signalized intersection and 250’ on each side of the signal.
TRAFFIC IMPACT:
The development will be required to implement the traffic improvements identified in the TIA for this development prior to COA.
TECHNICAL STANDARDS – NEW ROADS:
1. The position of the splitter islands hinder the width of the crosswalks. Crosswalks shall be a minimum of 6’, and 10’ is preferred. [Standard Detail 3-09 CofW Tech Stds]
2. The proposed Chastain Drive Typical cross-section detail does not meet city Technical Standards. Provide 5’ sidewalk and 6’ plaza sections on both sides of the street. [7-5 CofW Tech Stds] (Cond. # 16 and Cond. #22)
3. The site plans do not show the horizontal centerline radius for subdivision streets.
4. The subdivision streets do not appear to meet the minimum tangent length between reverse curves of 100’.
TECHNICAL STANDARDS – ACCESS (driveway, sidewalk, and sight distance):
5. Provide a sidewalk connection between the site and proposed parkland and active recreation areas.
6. Provide connections from the proposed sidewalk to the proposed 5’ wide asphalt pedestrian trails.
TECHNICAL STANDARDS – PARKING:
7. The proposed site has placed parking to the north of the emergency Turnaround Access on Webster Way. Please reposition the parking spaces.
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.
