I, (print) , a Colorado registered professional engineer, verify that construction
of all stormwater facilities and grading is complete and hereby submit this certification.
Please answer the following questions by initialing the appropriate response. For each question initialed “No,” attach an
explanation detailing how this will affect stormwater drainage for this lot and any adjacent lots.
1.Certification includes attached Stormwater-approved grading plan. (NOTE: City’s
Building Department does not approve grading plans).
2.Certification includes the attached as-built survey dated (must be within 60
days of the date the certification is submitted) accurately and truthfully depicting
elevations for:
Top of foundation/finished floor
Finished grade on each side of the structure
Quarter points along each lot line (not more than 50 feet apart)
Break points/high points
Swales
Berms
Retaining walls
Air conditioning pads
Window wells
Any other appurtenance(s) within an easement
3.All elevations are within a 0.2 foot tolerance of the approved grading plan.
4.The top of foundation is at least 6 inches above the highest grade surrounding the
structure.
5.There is a minimum grade of 5% away from the structure within the first 5 to 10 feet
adjacent to the residence.
6.All slopes meet or exceed the minimum requirement of 2% (1% is acceptable on single
family lots when the swale is draining the runoff from only two adjoining properties)
and are not steeper than 33% (3:1).
7.All flow lines of stormwater drainage swales are a minimum of 6 inches below the
elevation of ground adjacent to the structure and will direct drainage as shown on the
Stormwater-approved grading plan.
8.All downspout locations and discharge directions are shown on the as-built survey.
Runoff is directed into an appropriate drainage system or lot line swale, and it is not
directed onto neighboring properties.

THE APPROVED GRADING PLAN IS BASED ON LIDAR AVAILABLE DATA AND IS ON A DIFFERENT
DATUM, THE DIFFERENCES ARE CONSISTENT AND APPEAR TO BE WITHIN TOLERANCE

DUE TO CONFLICT OF SCHEDULE OF WHEN I RECEIVED THE SURVEY
TO WHEN THIS CERTIFICATION WAS PUT TOGETHER, IT WAS NOT
POSSIBLE FOR ME TO COMPLETE THE CERTIFICATION WITHIN THE 60
DAYS. I DID VISIT THE SITE, AND HAVE CONFIRMED THAT THE
SURVEY IS STILL ACCURATE AND DEPICTS THE CURRENT
CONDITIONS ON THE SITE. I VISITED THE SITE ON 09/05/2023, NOTED
THE LOCATIONS OF THE DOWNSPOUTS AND ADDED THOSE
LOCATIONS TO THE SURVEY.

14.Based on this information, I certify that (check one):
□The elevations and drainage patterns of the lot/site are in substantial conformance with the City
approved drainage and grading plan for the property (information attached).
□The elevations and drainage patterns of the lot/site as measured are in general conformance with the
City approved drainage plan with exceptions (information attached). In my professional judgment the
elevations and grading of the lot/site as constructed are functionally adequate and equivalent to the
specifically approved drainage plan, and will affect stormwater drainage on and off the lot/site in a
manner consistent with the approved drainage plan.
