Pleas e answe r the following questions by initialing the appropriate response. For eac h 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). N o 2. Certification includes the attached as-built survey dated -fy t*f/l ?-(must be within 60 No day s 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)' • Brea k points/high points • Swales*"" RetBimni • Air conditioning • Windo w well s • 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% awa y from the structure within the first 5 to 10 feet adjacent to the residence. 6. All slopes meet or excee d 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 swale s are a minimum of 6 inche s below the elevation of ground adjacent to the structure and will direct drainage a s shown on the Stormwater-approved grading plan. ». 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. 5/26/16 /4<?>q — 24-0 I Page I 9. A smoot h transition with no vertical offse t (step ) in grad e is provide d at the lot line to all No adjacen t properties . 10. The grading of this lot doe s not adversely affec t neighboring properties or City infrastructure. 11. Landscapin g has been completed prior to survey. If not, pleas e indicate who will be responsibl e for completing landscaping : IHCV^^Q^ H| f-j;J£, 12. Fina l site cleanu p has been completed . 13. I personall y visited the site as par t of the certification process , and in my professiona l opinion, the as-built surve y is an accurat e representation of the site conditions. 14. Base d on this information, I certify that (chec k one): D The elevation s and drainag e pattern s of the lot/site are in substantia l conformanc e with the Cit y approve d drainag e and grading plan for the propert y (information attached). 51 The elevation s and drainag e pattern s of the lot/site as measure d are in genera l conformanc e with the City approve d drainag e plan with exception s (information attached). In my professiona l judgment the elevation s and gradin g of the lot/site as constructe d are functionall y adequat e and equivalent to the specifically approve d drainag e plan, and will affec t stormwate r drainag e on and off the lot/site in a manne r consisten t with the approve d drainag e plan.

DRAINAGE DRAFTING OVERLOT GRADING OBSERVATION Sh e Observatio n Date : Sit e Observatio n Sit e Address : Sit e Legal : Advanced Engineering, LLC Proje$ Number:. Client Name: T> ~ 2A — Ol E L OZ-00^.00 I>»Tfe6Site Pla n and/o r Gradin g Pla n by : We have observed portions of the above referenced she. During our observations our representative measured the relative elevations at the lot sides and comers, top of foundation , and lowest openings. The observed elevations were compared to the Site Plan and/or Grading Plan referenced above. Based upon our finding s it is our opinion that: a The elevations as measured are in general conformance wit h the above noted Site Plan and/or Grading Plan. D The elevations as measured are in general conformance with the above noted She Plan and/or Grading Plan with the following exceptions: It is our opinion these exceptions, as noted above, should not adversely change the grading scheme as shown on the above referenced plan. S C During our observations our representative noted that the as measured elevations do not confor m to those indicated on die above referenced Site Plan and/or Grading Plan. However, it is our opinion die grades as measured should provide an adequate substitute to the above referenced grading scheme (see comments below). X- See the attached "As-Built" grading plan. n The elevations measured are not in conformance to die above referenced Site Plan and/or Grading Plan. Deficiencies include: Other comments and/or observations: IT- Uert>e*.T~f c***j£*. ± o-Va/gufif -rrty. rfrrfi*ffif l Limitations: It is our opinion die above referenced she, as graded on die observation date, should not mterfer e wim offsit e flow s unless die grades are changed or barriers are created such as fences, garden terracing, sidewalks, and/or any landscaping which may change die established flo w patterns by diverting or slowing runof f flow. Backfil l adjacent to die residence may settle over time, this settlement may allow ponding to occur adjacent to die foundatio n walls. To prevent this ponding and related problems, die backfill adjacent to die residence must be monitored and maintained to ensure that runof f will flow awa y fro m die foundation. The grades measured were compared only to th^^utttfln^to shown on die above referenced site plan and/or grading plan.
