Michael - Greg has informed Barratt that soils testing will be required on all lots prior rough grading sign-off and release for construction of the housing. Greg can provide you more detail if needed. - Peter

Subject: Potential Health Risk at Encinitas Tract 03-009, Barrett at Sheridan and Andrew
This letter is a request to evaluate potential health risks from soils that are potentially contaminated with greenhouse agricultural chemicals in Tract 03-009.
Tract 03-009, and the adjacent site, were excavated down approximately 2’
feet below grade. Approximately 8000 cubic yards were cut from the adjacent site and moved to 03-009 to make the final pad heights. There was no soil testing for agricultural chemicals below grade on either site.
Various reports from Leighton and Gradient document soils testing to a depth of 0” to 6”, find contaminants less than EPA limits, and conclude that these findings are similar to other studies where no significant sub su! rface contamination was found. No documentation of nega! tive su b surface soil test reports or literature searches for similar applications were provided to substantiate the conclusion.
The City’s soil consultant challenged the soil report conclusions as unacceptable, and determined that representative sub surface soil tests were needed to assure that there are no health risks from agricultural chemicals at this site, e.g., soil testing for agricultural chemicals is needed to assure that this project meets the standards of the City of Encinitas and that there is no possibility of worker, resident and neighbor exposure to hazardous materials.
Would you please assure that representative soil testing of Tract 03-009 is part of the final grading inspection. I suggest sampling at six sites on the surface, and at 1’ and 2’ below finished pad height.
Thank you, Michael Schwaebe
