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 only instances where 5% is not achieved is adjacent to building
entries, walkways, and where existing constraints restricted slopes
(ie, protection of an existing tree, etc)
The downspout locations and directions are not shown on
the asbuilt grading though were confirmed in the field.

9.A smooth transition with no vertical offset (step) in grade is provided at the lot line to all
adjacent properties.
10.The grading of this lot does not adversely affect neighboring properties or City
infrastructure.
11.Landscaping has been completed prior to survey. If not, please indicate who will be
responsible for completing landscaping:
12.Final site cleanup has been completed.
13.I personally visited the site as part of the certification process, and in my professional
opinion, the as-built survey is an accurate representation of the site conditions..

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.

A concrete curb and pan was installed per plan along the east property line. This does
create a step but maintains site runoff from entering the adjacent property.
It should be noted that this is project is redevelopment of a lot that previously had inadequate
drainage due to grade limitations. The improvements constructed improved the drainage
performance while working with existing constraints and protecting the new structures.
The site is generally clean though some activity was still
occurring on site, such as installation of the fence.
