Re: Drainage Certification for PVHS Medical Center Third Filing (Primary Care Plaza)
Dear Mr. -Harridan:
The purpose of this report is to complete the drainage certification for the PVHS Medical Center
Third Filing (Primary Care Plaza).
King Surveyors visited the site on June 5, 2005, to confirm the installation of the storm pipe,
structures,_ grading, and erosion control measures.
Grading around the building provides positive drainage away -from the building and meets the
intent of the proposed grading plan.
The two swales east of the private drives have been installed and drain east and into the swale
running along the east property line of the PVH Site. Riprap has been installed at the east ends of
the private drives; in accordance with the proposed plans. It is important to note that sediment
build-up has occurred in the swales during construction (see sheet CS26O).. The contractor is
cleaning/regrading these areas in accordance with the erosion control plan for the site.
Silt fence is not required along the east side of the Primary Care Plaza because grass is not yet
established in the swale running south along the east property line, and erosion control is being
provided by straw bales throughout the Swale (see sheet CS220 for details). Furthermore, silt
fence was not installed along the south side of the Primary Cara Plaza site to allow construction
equipment in and out of the site during construction of the parking lot. The contractor does not
intend to put up the 473' of silt fence along the south boundary and 313' along the east boundary
unless required. Therefore, if required, please have Bob Zakely contact Steve Cosgriff (Neenan
Company) at 303-710-1902. to discuss if the fence is necessary and when the fence canbe
removed.

_ 5 . Stan$ec
The two area inlets and corresponding storm drain system has been installed in the parking lot per
the approved plans..It is important to note that the slope of the storm drain (Storm Q) from the 5'
Type R inlet into storm manhole P-1 is 0.13%, rather than the approved 0.40%. Though this
slope is sub -standard, the hydraulic gradeline for this storm line remains 4.0'+ below finished
grade. Therefore, this slope should not pose any problems from a conveyance standpoint.
Overall, the majority of elevations observed for storm drainage features.were within construction
tolerances, except for Storm Q, as noted above. Therefore, the storm drain features and erosion
control methods constructed and provided appear to be in compliance with approved plans for
both the PVHS Third Filing (Primary Care Plaza), and also that of the PVHS Master
Infrastructure Second Filing.
This certification is signed and stamped. By signing this letter, I attest that to the best of my
knowledge, the conditions of the site are as shown on the attached redlined photocopy. Failure to
properly disclose all known information could result in the rejection of this certification and
prevent the release of any storm water utility holds on the Building Permit or Certificates of
Occupancy.
Thank you for your time and consideration of this submittal.
