(on development agreement)
I, (print) Kevin E. Forbes 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 storm water 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 attached as-built survey dated 3/9/2016 (must be within 60
days of date of certification) accurately and truthfully depicting elevations for:
• Top offoundation/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.
S. There is a minimum grade of 5% away from the structure within the firstS 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 25% (4:1) .
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 not directed toward neighboring properties.
