RE: Drainage Certification for Lot 17, Swift Addition to Fossil Lake P.U.D., City of Fort
Collins, County of Larimer, State of Colorado (aka 5938 Snowy Plover Court).
Dear Sirs:
On May 25, 2005, we observed the site located at 5938 Snowy Plover Court. The site had been
final graded. In addition to our observation, Absolute Surveying obtained spot elevations at
numerous spots throughout the site. Please refer to the attached elevation sheet.
Based on our observation and the attached survey information, the site appeared to drain away
from the building. In general, the southwest side of the house drains westerly towards Snowy
Plover Court and the northeast side of the house drains easterly to a concrete channel northeast of
the lot. The southeast side of the house drains easterly to the small swale between the two lots.
The northwest side of the house drains westerly to the small swale between the two lots. For the
southwest side of the house, the high point elevation is near the southwest corner of the garage.
For the southeast side of the house, the high point is near the southeast corner of the house. At
the high points, there is a sharp change in grade, as the design contours show.
The finished floor elevation given by Absolute Surveying is 92.18 feet, which is approximately
0.07 feet higher than the design elevation (92.11 feet). Based on the southeast property corner,
all lot corners are within 0.1 feet of design elevation, assuming the southeast property corner has
a design elevation of 90.12 and assuming the northeast and northwest surveyed spot elevations
are similar to the designed property corners.
The house has a below grade patio from the walkout basement. There are three floor drains
located in the floor of the patio. We did not determined where the discharge point for the floor
drains was located. Also at the northeast corner of the house, there is a depressed flat area just
south of the gutter down spout. This area may create a puddle near the house; please refer to the
attached pictures.
The site generally appears to conform to the Final Grading Plan — Sheet 17 of 56 — of Swift
Addition to Fossil Lake P.U.D. — prepared by Northern Engineering Services, Inc., dated
1/10/03.
Our certifications were based on our observation on the date noted above. The geotechnical
report was not provided to us for this site. We therefore cannot determine if the site has been
graded according to the geotechnical report.
If you have any questions, please contact me at the above address or phone number.
Sincerely,
ZOO*" & vl"M atea, 909c.
