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.

Downspout locations were observed and photographed during my site visit on December 11, 2019.
The as-built condition is adequate. Refer to the ILC for the downspout locations.
Air Conditioning (AC) pads were observed and photographed during my site visit on December 11, 2019.
The AC pads (and downspout locations) are shown on the Improvement Location Certificate (ILC).

This inlet grate elevation can be adjusted with
the plot plan for 302 Skyraider Way. Galloway
& Company, Inc. (Galloway) will be preparing
this plot plan. The approved drainage design
proposed no inlet in this area. Basin M5 was
designed to drain into Timberline Road and
then back into the project site via Crusader
Street. In the interim runoff from this southwest
corner of 314 Skyraider Way draining south/
southwest should have a negligible impact.

This inlet was not constructed. It was neces-
sary with the proposed sidewalk because the
sidewalk would have been a local high point.
Without the sidewalk, runoff can drain to the
existing inlet - further north. This drainage pat-
tern more closely matches the approved
drainage design. The northerly inlet grate is a
Nyloplast 18” Pedestrian Grate (the approved
design called for a Nyloplast 15” Pedestrian
Grate). It should have adequate capacity with
a 50 percent clogging factor applied. If it
clogs, water will overtop the walk to the west
and drain into Timberline Road.
