I, (print) Megan L. Keefe 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 No_____Yes
Building Department does not approve grading plans).
2. Certification includes the attached as-built survey dated 11/16/23 (must be within 60 No__________________Yes
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.

9. A smooth transition with no vertical offset (step) in grade is provided at the lot line to all No
adjacent properties.

infrastructure.

responsible for completing landscaping:________________________________

13. I personally visited the site as part of the certification process, and in my professional No
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.

NOTES:
1.CONTRACTOR TO PROVIDE AND MAINTAIN ALL NECESSARY EROSION CONTROL MEASURES PRIOR TO AND THROUGHOUT
CONSTRUCTION. PLACE EROSION CONTROL PROTECTION AT ALL EXISTING INLETS DOWNSTREAM FROM THE CONSTRUCTION AREA.
EROSION CONTROL PROTECTION SHALL REMAIN IN PLACE UNTIL CONSTRUCTION IS COMPLETE AND ALL DISTURBED GROUND IS
ADEQUATELY VEGETATED WITH OWNER'S APPROVAL FOR REMOVAL.
2.THE EXTENT OF EROSION CONTROL PROTECTION SHALL BE OBSERVED AND ADJUSTED AS NEEDED DURING CONSTRUCTION BASED ON
SITE CONDITIONS AND THE PERFORMANCE OF THE EROSION CONTROL CONTROL MEASURES SHOWN, TO SUPPLY SUFFICIENT EROSION
CONTROL AND MINIMIZE DOWNSTREAM WATERWAY POLLUTION.
3.LIMIT DISTURBANCE TO AREAS WITHIN EROSION CONTROL BOUNDARIES. ADJUST EROSION CONTROL BOUNDARIES AS NECESSARY TO
ADEQUATELY COMPLETE PROPOSED WORK. ALL DISTURBED AREAS SHALL BE PREPARED (SEEDED & MULCHED, SURFACE ROUGHENING,
ETC.) TO MINIMIZE EROSION POTENTIAL AND SOIL MIGRATION.
4.SEE LANDSCAPE PLAN FOR REVEGETATION METHODS AND DETAILS. DURING CONSTRUCTION, ANY SOIL DISTURBED AND NOT UNDER
ACTIVE CONSTRUCTION SHALL BE SEEDED AND MULCHED PER LCUASS STANDARDS.
5.ANY DISTURBED LAND MUST RECEIVE SURFACE ROUGHENING, INCLUDING BUT NOT LIMITED TO SLOPED AREAS.
6.AREAS THAT EXPERIENCE EROSION ISSUES FROM STEEP SLOPES OR WATER EROSION RESULTING IN SEED NOT BEING ABLE TO ESTABLISH
DURING THE FIRST GROWING SEASON SHALL REQUIRE RESEEDING AND EROSION CONTROL BLANKETS TO STABILIZE THE SOIL.
7.NO DEBRIS OR SEDIMENT SHALL BE TRACKED ONTO ALLEY OR PUBLIC STREET. IN CASE ANY TRACKING DOES OCCUR, CONTRACTOR
SHALL SWEEP AND CLEAN IMMEDIATELY.
8.SEE SHEET 2 FOR SUPPORTING DETAILS AND CITY OF FORT COLLINS EROSION CONTROL NOTES.
