DRAINAGE SWALES

Dear Ms. Tornillo:
In accordance with your request, we prepared this revised letter to provide our opinion regarding the
precise grading of sideyard swales along residential units within the subject development. We revised
the previous letter to include swales that are closer than originally estimated.
We understand drainage swales will be located 3 feet from the structure perimeter with a minimum
drainage gradient of 2 percent in accordance with City of Carlsbad Standard Drawing GS-1 5, Case 2.
Based on discussions with the project civil engineer, we understand the depths of the swales will
range between 0.1- and 0.3-foot below the planned pad elevations. We opine the planned swales can
be constructed from a geotechnical engineering standpoint. We understand the foundations for the
planned structures will be post-tensioned; therefore, the foundations do not need to be deepened.
Should you have any questions regarding this letter, or if we may be of further service, please contact
the undersigned at your convenience.
Very truly yours,

Dear Ms. Tomillo:
In accordance with your request, this letter has been prepared to provide our opinion regarding the
precise grading of sideyard swales along residential units within the subject development.
If drainage swales are planned for a location within 5 feet from the structure perimeter, the footings
should be deepened to accommodate minimum foundation embedment. We recommend that the
location of the deepened footing be shown on the plot plans. We understand that Geocon
Incorporated will be provided copies of the plot plans and will observe in the field that the deepened
footings are properly excavated during the foundation excavation observation.
