The private road plan for Newcomb Mountain Lane,received on 07 August 2007,has been reviewed. The
engineering review for current development recommends approval of the road plans when the following
items are adequately addressed:
A.Road plan and drainage computation comments:
1. The revision of the cul-de-sac to a hammerhead turn around is acceptable with the following
changes:
• Please revise the hammerhead design to the following standards:the radius of
pavement=30',the length of the hammerhead pavement= 50' as measured from
the centerline of Newcomb Mountain Lane.
• Please provide a temporary hammerhead turnaround at the end of proposed street
construction of Rosemont Subdivision. This is needed to provide a turnaround if
the remainder of Newcomb Mountain Lane is not bonded or built.
• Please revise the final subdivision plat that provides the 40' access easement to
include the new turnarounds for Newcomb Mountain Lane.
Rev. 7: The first two parts of this review comment have been adequately addressed
with this plan submittal. The applicant still needs to submit a revised plat for the access
easement and private street to accommodate the changes to the street plan. This comment
affects the final plat approval only. The private street plans can be recommended for approval.
2. The road bond amount is for HCM is$401,000.00. The road bond amount for The Rocks,
LLC is$83,000.00. Please contact Ms. Pam Shifflett at 434.296.5832 Ext. 3246 for more
information on the posting of this road bond.
3. The road bond needs to be posted and approved before Engineering will recommend approval
to the final subdivision plat.
