13. I personally visited the site as part of the certification process, and in my professional No -Yes T4
opinion, the as-built survey is an accurate representation of the site conditions.
14. Based on this information, I certify that (check one):
0 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).
Lv" 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.
