3. Design Changes – Sanitary Sewer Main & Laterals
3WATERSHED PROJECTS IMPLEMENTATION BRANCH – SOUTH, STORMWATER PLANNING DIVISION
Hayfield Road Pipe Conveyance Project
 Existing sanitary main under the median strip & property service lateral
connections pose elevation conflicts with storm conduit elevation
• Known early on
• Original design included only 10 homes
• Shared in prior HFCA meeting presentations
 Approaching the 95% plan review, it became apparent that design did not
allow sufficient cover (i.e., distance or separation) between the necessary
pipe installation work & the remaining sanitary laterals
• Laterals are owned & maintained by individual property owners
• New sanitary laterals will be installed to just behind the side walk -
on the residence side of the side walk

4. 4
 CCTV inspection of the existing main & all the laterals (23 properties) on the west side of
Hayfield Road
• Complete on September 29
• Final report due to the County in November
• Condition report will be shared with each of the 23 property owners
 New laterals must be installed according to the VUSBC (Va. Uniform Statewide Building Code)
• Contractor will secure necessary Plumbing permit to complete the work
• Inspection & approval is required before the contractor can backfill the work &
continue
• Each property owner will be provided a copy of the permit & evidence of
inspection approval

Design Changes – Sanitary Sewer Main & Laterals
 Contractor will be required to provide a minimum 48-hours advance
notice prior to making the cross-over to the new lateral
 Extending the new/parallel sanitary main drives the new storm pipe &
box culvert toward the median strip
• Additional impacts on the median curb & gutter
• As always VDOT & design requirements have driven impacts to the
median
• We continue to seek ways to minimize landscape impacts
o During Bowman’s design efforts
o Even to the point of making field decisions during construction,
if possible

 Started relocation work on September 6, 2017
 Work scheduled to be complete in January 2018
 WGL reports:
o Main is a little more than 50% complete
o Challenge – only 3 individual service
connections completed of approximately
60 needed
 WGL has been very responsive to the
County’s requests. Not having heard
any news, presumably they have been
good neighbors in the community.

Continuing Communication
WATERSHED PROJECTS IMPLEMENTATION BRANCH – SOUTH, STORMWATER PLANNING DIVISION
Other thoughts:
 Offer suggestions on how best to communicate with
the community at-large
 When is next HCA meeting date?
 As soon as construction contract awarded, we will return to:
• Share their construction schedule
• Identify key contractor personnel
• Discuss continuing/on-going progress meetings with HCA
 What did I miss?
 Anything else?
