The elevations and drainage patterns are as shown on the attached as -built drawings which were developed from surveys performed on April 11 and April 19, 2014. The elevations, drainage facilities, and drainage patterns for the above referenced lots are in general conformance with the City approved drainage and grading plan and site certification checklist for the property with minor grading exceptions. All grading exceptions with a variation of over 0.25' from the approved grading plan have been circled in red on the attached As -built Exhibit & Approved Grading Plan Comparison sheet. The variations are as follows: 1. The swale to the west of the building is constructed approximately 0.25' higher than designed due to higher existing street elevations; however, the drainage design intent is still met. 2. The front porch elevation of 41.80' is over a foot higher than the approved grading plan spot elevation. This change in elevation is due to differences in the construction of the steps with the grading plan. Positive drainage away from the building is maintained and drainage design intent is still met. Please see the attached Commercial, Multi -Family and Subdivision Certification Checklist for a detailed list of stormwater certifications. If you have any questions concerning our inspection or certification, please feel free to contact us.
