Lot: Block:
Subdivision:
Permit Application #:
Larimer County Parcel #:
Larimer County Reception #:
(on development agreement)
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.

M.R.
Drainage, in some locations, designed to flow onto sidewalks or sidewalk chases closer than 5' from building. The northeast corner is less than minimum
slope due to conflicts with conduits and electric meters. There is minimal stormwater runoff at that location and downspouts have been routed directly to
the sidewalk chase. No adverse effects are foreseen.
Concrete pans used in this area adjacent to structure
1% swale slope utilized along west side of building. Swale conveys minimal stormwater runoff and no runoff from downspouts. No adverse effects forseen
and drainage will be directed per the approved grading plan. Concrete pans used for grades < 1%

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.

No Yes
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.

5.LOT GRADING IS DESIGNED FOR TYPICAL RECTANGULAR FOOTPRINT WITH
DIMENSIONS AS SHOWN HEREON. SHOULD BUILDING FOOTPRINT CHANGE, GRADING
SHALL BE ADJUSTED BY PLOT PLAN FOR THE SPECIFIC FOOTPRINT. ALL MINIMUM
OPENINGS SHALL BE A MINIMUM OF 18" ABOVE FRONT LOT ELEVATIONS AND PLOT
PLAN DESIGN SHALL MEET FHA GRADING GUIDELINES AND BUILDING CODE
REQUIREMENTS.
6.THE DEVELOPER SHALL OBTAIN A FLOODPLAIN USE PERMIT FROM THE CITY OF FORT
COLLINS AND PAY ALL APPLICABLE FLOODPLAIN USE PERMIT FEES PRIOR TO
COMMENCING ANY CONSTRUCTION ACTIVITY (BUILDING OF STRUCTURES, GRADING,
FILL, DETENTION, PONDS, BIKE PATHS, PARKING LOTS, UTILITIES, LANDSCAPED AREAS,
FLOOD CONTROL CHANNELS, ETC.) WITHIN THE CANAL IMPORTATION FLOODPLAIN AND
FLOODWAY. ALL ACTIVITIES WITHIN THE FLOODPLAIN ARE SUBJECT TO THE
REQUIREMENTS OF CHAPTER 10 OF THE FORT COLLINS MUNICIPAL CODE.
7.CONSTRUCTION OF NEW STRUCTURES, HARD SURFACE PATHS, WALKWAYS,
DRIVEWAYS, WALLS, AND PARKING AREAS IS PROHIBITED IN THE FLOODWAY UNLESS
NO-RISE CONDITIONS ARE MET, PER SECTION 10-45 OF CITY CODE. ANY
CONSTRUCTION ACTIVITIES IN THE REGULATORY FLOODWAY MUST ALSO INCLUDE A
NO-RISE CERTIFICATION PREPARED BY A PROFESSIONAL ENGINEER LICENSED IN

1.ALL EXISTING TREES WITHIN THE LIMITS OF THE DEVELOPMENT AND WITHIN ANY NATURAL AREA BUFFER ZONES SHALL
REMAIN AND BE PROTECTED UNLESS NOTED ON THESE PLANS FOR REMOVAL.
2.WITHIN THE DRIP LINE OF ANY PROTECTED EXISTING TREE, THERE SHALL BE NO CUT OR FILL OVER A FOUR-INCH DEPTH
UNLESS A QUALIFIED ARBORIST OR FORESTER HAS EVALUATED AND APPROVED THE DISTURBANCE.
3.ALL PROTECTED EXISTING TREES SHALL BE PRUNED TO THE CITY OF FORT COLLINS FORESTRY STANDARDS. TREE
PRUNING AND REMOVAL SHALL BE PERFORMED BY A BUSINESS THAT HOLDS A CURRENT CITY OF FORT COLLINS
ARBORIST LICENSE WHERE REQUIRED BY CODE.
4.PRIOR TO AND DURING CONSTRUCTION, BARRIERS SHALL BE ERECTED AROUND ALL PROTECTED EXISTING TREES WITH
SUCH BARRIERS TO BE OF ORANGE FENCING A MINIMUM OF FOUR (4) FEET IN HEIGHT, SECURED WITH METAL T-POSTS,
NO CLOSER THAN SIX (6) FEET FROM THE TRUNK OR ONE-HALF (½) OF THE DRIP LINE, WHICHEVER IS GREATER. THERE
SHALL BE NO STORAGE OR MOVEMENT OF EQUIPMENT, MATERIAL, DEBRIS OR FILL WITHIN THE FENCED TREE
PROTECTION ZONE.
5.DURING THE CONSTRUCTION STAGE OF DEVELOPMENT, THE APPLICANT SHALL PREVENT THE CLEANING OF EQUIPMENT
OR MATERIAL OR THE STORAGE AND DISPOSAL OF WASTE MATERIAL SUCH AS PAINTS, OILS, SOLVENTS, ASPHALT,
CONCRETE, MOTOR OIL OR ANY OTHER MATERIAL HARMFUL TO THE LIFE OF A TREE WITHIN THE DRIP LINE OF ANY
PROTECTED TREE OR GROUP OF TREES.
6.NO DAMAGING ATTACHMENT, WIRES, SIGNS OR PERMITS MAY BE FASTENED TO ANY PROTECTED TREE.
7.LARGE PROPERTY AREAS CONTAINING PROTECTED TREES AND SEPARATED FROM CONSTRUCTION OR LAND CLEARING
AREAS, ROAD RIGHTS-OF-WAY AND UTILITY EASEMENTS MAY BE "RIBBONED OFF," RATHER THAN ERECTING PROTECTIVE
FENCING AROUND EACH TREE AS REQUIRED IN SUBSECTION (G)(3) ABOVE. THIS MAY BE ACCOMPLISHED BY PLACING
METAL T-POST STAKES A MAXIMUM OF FIFTY (50) FEET APART AND TYING RIBBON OR ROPE FROM STAKE-TO-STAKE
ALONG THE OUTSIDE PERIMETERS OF SUCH AREAS BEING CLEARED.
8.THE INSTALLATION OF UTILITIES, IRRIGATION LINES OR ANY UNDERGROUND FIXTURE REQUIRING EXCAVATION DEEPER
THAN SIX (6) INCHES SHALL BE ACCOMPLISHED BY BORING UNDER THE ROOT SYSTEM OF PROTECTED EXISTING TREES
AT A MINIMUM DEPTH OF TWENTY-FOUR (24) INCHES. THE AUGER DISTANCE IS ESTABLISHED FROM THE FACE OF THE
TREE (OUTER BARK) AND IS SCALED FROM TREE DIAMETER AT BREAST HEIGHT AS DESCRIBED IN THE CHART BELOW:
9.NO TREES SHALL BE REMOVED DURING THE SONGBIRD NESTING SEASON (FEBRUARY 1 TO JULY 31) WITHOUT FIRST
HAVING A PROFESSIONAL ECOLOGIST OR WILDLIFE BIOLOGIST COMPLETE A NESTING SURVEY TO IDENTIFY ANY ACTIVE
NESTS EXISTING ON THE PROJECT SITE. IF ACTIVE NESTS ARE FOUND, THE CITY ENVIRONMENTAL PLANNER WILL
DETERMINE WHETHER ADDITIONAL RESTRICTIONS ON TREE REMOVAL AND CONSTRUCTION APPLY.
10.PRIOR TO ANY ONSITE DISTURBANCE PLEASE CONTACT CITY FORESTRY AT CTOMLINSON@FCGOV.COM FOR
COORDINATION OF TREE PROTECTION REQUIREMENTS.
11.HYDRO-EXCAVATION OR AIR SPADING SHALL BE DONE AT THE FURTHEST EDGE OF THE DISTURBANCE AREA WITHIN THE
CRITICAL ROOT ZONE OF THE TREE DEFINED AS 1 FT. RADIUS FROM THE TRUNK FOR EACH INCH OF DIAMETER
MEASURED AT 4.5 FT FROM THE GROUND (DBH). AT THE EDGE OF DISTURBANCE, A 2 FT DEEP AND 6 IN WIDE TRENCH
WILL BE MADE TO EXPOSE ANY EXISTING ROOTS USING A PRESSURE SETTING OF LESS THAN 1800 PSI. ALL ROOTS OVER
3 INCHES IN DIAMETER WILL BE INSPECTED BY THE FORESTRY DIVISION PRIOR TO CUTTING OR DISTURBING. ANY ROOT
UNDER THIS DIAMETER WILL BE CUT CLEANLY AT THE FURTHEST POSSIBLE POINT AWAY FROM THE TREE WITH A SHARP
HAND SAW (NO ROTARY BLADE OR CHAINSAW). THE TREE WILL BE KEPT WELL-WATERED DURING THIS WORK MAKING
SURE THE SOIL STAYS MOIST TO A DEPTH OF 12 IN UNTIL PERMANENT IRRIGATION IS INSTALLED. ALL TREE PROTECTION
TO STAY IN PLACE UNTIL THIS PROCESS IS COMPLETED. PRIOR TO PERFORMING THIS ACTIVITY PLEASE CONTACT THE
FORESTRY DEPARTMENT TO ENSURE THAT ALL HYDRO-EXCAVATION IS APPROVED PRIOR TO START.
12.SEE LANDSCAPE PLANS FOR TREE PROTECTION DETAIL.
13.IN AREAS WHERE THE CRITICAL ROOT ZONE WILL BE IMPACTED, CONTRACTOR SHALL HAND-EXCAVATE TO THE EXTENT
POSSIBLE. IF ROOTS LARGER THAN 2" IN DIAMETER ARE ENCOUNTERED, NOTIFY THE LANDSCAPE ARCHITECT
IMMEDIATELY.
