Re: Lot 52, Block 10, Fossil Lake P.U.D., First Filing
3282 Rock Park Drive; Fort Collins, Colorado
Dear Jay,
This letter serves as final certification for the above referenced address according to the
requirements of the Stormwater Utility in the Stormwater Building Permit Notice for this address
and dated 08/19/2002. Certifications include the items noted on the Stormwater Building Permit
Notice and are as follows:
• Grading certification
• Swale certification
• Finished floor elevation certification
• Property lot corner elevation certification
• Lowest building opening elevation certification
The original grading plan for this site was prepared by DSDA Residential of Denver, Colorado.
We have visited this site on several occasions. On our initial visit, it was noted that the structure
provided had a walk -out / walk-up condition. Rear foundation wall heights met garden level
conditions. Field shots were provided at the initial visit and it was determined that runoff from
the rear of the house could not simply sheet flow to the open space areas without lot specific
grading modifications. Note that the subdivision grading plan did not necessarily accommodate a
garden level condition.
Due to the above described constraints, Shear Engineering Corporation has developed a
modification to the site specific grading plan. The initial grading design modification was
presented to the Homeowner's Associated and denied due to two (2) points of discharge to the
open space area. The plan was further modified to allow a single discharge point from the lot to
the open space area. Given the size of the house, the proximity of the structure to the property
lines, the walk -out / walk-up condition of the basement, and the fixed elevations of the open
space tract that borders this lot on the southern and eastern sides, sheeting into the open space
tract could not be achieved.
Due to the constraints noted, the slope of the rear yard swale will be approximately 1.26%. The
swale will be incorporated into the landscape plan and will not be sodded.
