Subject: Lake Frederick Water Tank setback/site plan narrative
Mark,
Per our discussion, I have drafted the below narrative which addresses the setback requirement for the Lake Frederick
elevated water tank. The proposed elevated water tank, possibly a composite elevated storage tank (CET), will be
approximately 160 -ft tall, and have a concrete pedestal base with an approximate 40 -ft diameter. CETs are concrete
structures designed to withstand natural events such as wind storms and earthquakes. CETs are designed to meet or
exceed AWWA D107 &D102 standards. And most importantly, CETs are permanent structures akin to masonry buildings
and are not designed for intention collapses like cellular towers. A good resource for CET information is at
http://caldwellwatertanks.com/tank-composite-overview.htmi (this is not an endorsement of Caldwell, but I found their
website to be informative).
As background, the existing elevated water tank located at 315 Tasker Road (Frederick Water Administration Building) is
190 feet tall and has a 60 foot setback from the northern property line (closest property boundary). The proposed Lake
Frederick elevated water tank will be approximately 30 -ft shorter, yet have greater setbacks when compared to the
existing elevated water tank at 315 Tasker Road.
With your approval, the following narrative will be placed on the Lake Frederick Elevated Water Tank's site plan.
"Setbacks applicable to the proposed elevated water storage tank: The base of the elevated water storage tank will be a
minimum of 70 -ft from Route 277 (Fairfax Pike), 100 -ft from the Madison Farms, LLC property to the west, and 250 -ft
from the southern property line. These setbacks result in an elevated water storage tank location that accommodates
the dedication of 20 -ft for future Fairfax Pike expansion, and avoids placing the tank within the planned South Frederick
Parkway alignment. The Zoning Administrator, per Frederick County Code 165-204.26.A. Public Utilities, and reflective
of the approval of the site plan, has determined that these are appropriate setbacks applicable for the elevated water
storage tank on this site."
Taken from County Code....
165-204.26 Public utilities. Lot requirements for lots used by political subdivisions, municipal corporations, the
Virginia Department of Transportation, the Frederick -Winchester Service Authority, or the Frederick County
Sanitation Authority for public utility purposes shall be as follows:
/&M
In all zoning districts, the Zoning Administrator shall have the authority to determine the minimum lot size
necessary for such public utilities and the appropriate setbacks for such lots used for pub is utility purposes.
B.
Such lots shall be exempt from the individual on-site sewage disposal system requirements.
C.
Such lots may be accessed by private access easernents; any such easement shall be a minimum of 15 feet in
width.
Please let me know if you have questions, and if you are agreeable to accepting this narrative as part of the site plan.
Thank you.
