Commissioner Fox referred to the original plan for the school where access was to be from Busch Road. She was not sure at the time the second Ponderosa project was approved what the timing for building the school would be if the School District took the option. She questioned whether the Busch Road connection to EI Charro Road was supposed to have happened before the theoretical school was to be built, or whether the school was going to be built with no other traffic mitigations. Mr. Tassano replied that he would not know if they would have linked Busch Road extension to EI Charro Road with the construction of a high school; however, without EI Charro Road extending all the way to Stoneridge Drive and then Stoneridge Drive extending to provide more of a high school service, extending to the east would not be something that would alleviate a lot of trips as far as getting to the high school. With reference to the EVA, Commissioner Fox noted that there have been a couple of fires in the Mohr-Martin area, and one home actually burned to the ground. She questioned what Traffic Engineering's emergency response was, given a gated community and the two fires in the area. Mr. Tassano replied that Traffic did not evaluate the project in relation to gating but believed that it would be required to have Opticom, which can be used on the gates as well as on traffic signals. He added that for gated access, Opticom is much better than a Firefighter getting out of his truck and unlocking the gate, with the possibility of the key not working or the presence of sand or grit problems. Mr. Otto stated that the project was reviewed by the Fire Marshal who worked with the applicant as far as the EVA locations, and the proposed plan was acceptable to the Fire Marshal. Commissioner O'Connor requested an explanation of the number of trips for seniors and whether those trip numbers reduced as seniors aged. Mr. Tassano replied that there appears to be a greater need for this type of senior housing as evidenced in its expansion within the past 10 to 15 years. He stated that only a limited number of studies have been done by ITE in the last 20 years, and there was a more recent study in 1996 that reviewed this and determined that the numbers in the current IT trip generation manual were accurate. He added that there was another study done in 2007 on a small scale of four to five sites to see if the ITE rate was representative of 55-year-olds and older. He noted that no study has been done for 62 years, 65 years, or older and that the only break available is for 55 years and older for attached homes and detached homes, and continuing care for a much more elevated rate with an average age of 75 years. He stated that the study looked at what is the highest senior housing rate, using .53 per household, and that the maximum numbers do not yield a significant impact as they disperse.
