February 17, 2025 1 To: Mayor Balch, City Council Members, City Manager and Staff From: Carol Olson, Resident of The Village at Ironwood Subject: Arroyo Lago Contaminants, history of Busch Pitt, and removal of seasonal bird migration water location by imported landfill, apparently unauthorized. I, together with the residents of The Village at Ironwood, live in a 55+ community. However, we, and at least half of the residents are 65-75 years old. The toxicity levels for the contaminants which are addressed in the Draft EIR DO NOT ADDRESS THE INCREASED SENSITIVITY TO THOSE COMTAMINANTS FOR THE ELDERLY!!! The Draft EIR does not address the reduces tolerance levels of their next-door communities like ours! Our interest in the Proposed development in this context stems from the prior use of the land for Hanson Aggregates Radom Facility, soil fill after usage, and various dumping and use of “Ponds” with backfill materials which had contained hazardous material s. Having gone through much, but not all, of the Appendix F, (7218 pages) it is astonishing that anyone would consider living in such an Arroyo Lago area! With increased age, we would not have moved here if we knew of the reduced quality of life and life expectancy upon doing so. All of the issues contained in the Hazards section 3.2 and 3.8 of the Draft EIR, while important on an individual basis, will have a measurable impact on the Health and Safety of the existing residents. A summary of those which have been studied in the allotted time are described here, as best as could be done in such a short time for the following: • For the general population, as was done fin the Draft EIR, and • For the elderly population which are most impacted by the proposed development Impact areas: 1) Even though some tests and borings at different times and locations were made in the most obvious hazardous locations, see figures below from the report dated Oct 26, 2007 through 2017 (maybe more) they were performed in the site, namely in AOC 6 (Busch Pit) AOC 7 and EB-35 for example. The fact that residual hazardous materials such as Chromium, Arsenic, other Heavy Metals, and hydrocarbons, for example, in the original or fill materials is alarming. (see Appendix F report) last 25% of the report on test borings, etc. page ~5140 onward. The levels provided in the Draft EIR are the dominant consideration for the target population for a community development, so we assume. However, the hazardous levels for the elderly are obviously less than for the general population because of their reduced immune system functions and general aging of their bodies and minds. It is both physical and mental acuity which set the levels of hazardous environmental resistance which affect our elderly communities.
