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 attached as-built survey dated (must be within 60 days of date of certification) accurately and truthfully depicting elevations for: z Top of foundation/finished floor z Finished grade on each side of the structure z Quarter points along each lot line (not more than 50 feet apart) z Break points/high points z Swales z Berms z Retaining walls z Air conditioning pads z Window wells z 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 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.

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): Ƒ 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). Ƒ 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.

An earth drainage swale is indicated in Common Area A, Kechter Crossing Planned Land Division, as shown on the Final Grading Plan – 30 Scale (sheet 21 of 55), in order to convey runoff from the rear yards of Lots 5, 6, 7 and 8, Block 12, Kechter Crossing Planned Land Division and the side yard and portions of the rear yard of Lot 1, Block 12, Kechter Crossing Planned Land Division and Lots 1 and 8, Block 11, Kechter Crossing Planned Land Division to a public storm sewer system in Crossview Drive. At the time the Grading Certification for Lot 8, Block 12, was prepared, it appears that the earth drainage swale on the north side of Lots 7 and 8, Block 12 (the south side of Lot 1, Block 11) was not constructed properly and drainage is not being adequately conveyed to the west to the earthen drainage swale that was constructed properly. We have spoken with Meritage Homes about this issue and understand that they are working with the developer of Kechter Crossing to get this issue resolved. It is our professional opinion that the impact of the inadequate conveyance of drainage that currently exists in Common Area A will be limited to localized shallow ponding of water within Common Area A and will not impact Lot 8 Block 12, Kechter Crossing Planned Land Development. Our lot grading certification was limited to a review of surface drainage and did not include a specific review of the groundwater elevation and the required 3’ separation from the basement floor. We have assumed that this review was performed by others during the structural design to ensure that the required separation was met.
