SWQMP ADDENDUM
BMP-1, located within the Lot 9 project, was required to be relocated & reshaped to avoid an existing
slurry cap.
The shape of the BMP was narrowed along the eastern side of the biofiltration and widened on the
western side. The change in shape resulted in a BMP footprint of 940 sqft. The original BMP footprint
was 937 sqft. The net change in square footage resulted in an increase of 3 sqft to the treatment and
storage area. All aspects of BMP-1 (ponding depth, gravel storage depth and basin materials) remain
unchanged.
Due to BMP-1 being designed and approved at a smaller footprint, the increased size of BMP-1 is
expected to perform at or above the approved design. No further analysis is needed.

Declaration of Responsible Charge
I hereby declare that I am the engineer of work for this project. That I have exercised responsible charge
over the design of the project as defined in section 6703 of the business and professions codes, and that
the design is consistent with current design. I understand that the check of the project drawings and
specifications by the City of Carlsbad is confined to a review only and does not relieve me, as engineer of
work, of my responsibilities for project design.
