Re: Albemarle Place (aka Stonefield) WP02010 -00023
Dear Herb,
I have reviewed your resubmittal of March 18'' against the comments previously supplied by Phil Custer of
this office. Based on that review, I am approving the referenced plan subject to the following conditions:
1. Per comment #4 from March 18th, approval of this plan and the Erosion and Sediment Control
Plan associated with a final site plan shall require a determination that Minimum Standard 19 (per
Va. E &SC Regulations) has been satisfied. As noted in this comment, that analysis shall be
undertaken following a review by the City of the downstream channel analysis. I appreciate you
forwarding the inspections video of the 42" pipes under Route 29. While the video illustrates a
number of minor seeps affecting the long -term life of the structures, I saw no evidence of problems
that would suggest this project would create an immediate threat to the stability of the structures.
2. Prior to issues of approval for a final site plan utilizing this storm-water management plan, a
stomwater management agreement and bond that satisfies the County Engineer and County
Attorney must be accepted by the County. I have not calculated a bond amount at this time, but
will do so as part of the review of the final site plan. If you require a bond estimate in the near
term, please let me know.
Finally, while not a condition of approval, I do want to note several issues that I believe are important to
you and your client.
A. Please note that a large amount of the proposed storm sewer appears to be at depths that may
exceed the rating for Class III RCP. I assume either you or the construction manager will address
this depth to pipe classification prior to installing any of the structures.
B. Without a site plan showing the location of buildings in relationship to the storm sewer is possible
at this time. Related to "A." above, it is not possible to determine if the pipes are in the load plane
of any building foundations. Please be prepared to address this issue during review of the site
plans.
C. Given the development is largely commercial in nature, we anticipate all of the onsite stomrwater
management facilities and storm sewer will remain the responsibility of the property owner. The
stormwater management agreement(s) will provide the County the ability to enter the site for
inspections and/or repairs if the owner fails to provide those repairs, but the facilities shall remain
the responsibility of the property owner.
D. Finally, while I believe this plan can be constructed, it is a complicated plan and will require a lot
of careful coordination during construction. The County's focus in on assuring compliance with
the approved plan and public safety, not construction procedures. To this end, we encourage the
construction manager to work closely with the County inspector to assure no permit violations are
created during construction. We all understand that this project's proximity to Route 29 creates a
risk of serious impacts to public safety and welfare from a failure. Thus, the inspector will be
visiting this site more often than most and will expect the contractor to maintain site integrity at all
times.
Should you have any questions or concerns with this approval, I will be happy to address them with you.
Sincerely,
Mark B. Graham, P.E.
Director of Community Development
