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.

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.. No Yes No Yes No Yes No Yes 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.

All elevations are within a 0.2 foot tolerance of the approved grading plan. There are several as built elevations that exceed the 0.2 foot tolerance. The high point in the side-yard swale was shifted by approx. 20 feet. There is still adequate fall away from the building and the minor shift in the high point location will not impact downstream drainage facilities. I consider the grading to be in general conformance of the approved grading plan. 4. The top of foundation is at least 6 inches above the highest grade surrounding the structure. There are several locations where the finish grade is only 4” below the top of foundation. However, the grades away from the structure adjacent to these locations are over 10% which will ensure water is not ponding near the foundation. All roof drains are directed away from the structure to the invert of the swales along the property lines which will also keep water away from the foundation. roof drain downspout location Lot 38 2051 Lot 37 2049 CD N # 3 0 1 6 A 0 2 2 06 3 0 1 6 CD N # 3 0 1 6 A 0 2 2 06 3 0 1 6
