RE: Certification of Bio Basin Grades (BMPs A, B, C, D, E, F, and G)
Precise Grading Plans for Carlsbad Oaks North Lot 7 (Map No. 14926) City of Carlsbad Drawing No. 494-2A, Project No. SDP 16-03 To Whom it May Concern: Excel Engineering performed several field surveys relating to the seven installed bioretention basins on the above-referenced project. The field surveys consisted of the following: - Basin bottom excavation (April 12 and 26, 2018) - Top of rock placement (April 26 and May 10, 2018) - Finish surface and pipe works (September 7, 2018) In all cases, the bioretention basins’ grades were found to be constructed in substantial conformance with the approved grading plans for the City of Carlsbad.
