Why is the model so wrong? Almost every dial turned against us: • 13% higher population of employed individuals than multi-family average and directly comparable property • IMPACT: More daily trips • 44% higher job density for our site per SQF than surrounding comparable land uses • IMPACT: More daily trips • 2/3 less walking from our site than surrounding areas, despite next door retail center and walking trail connecting the river • IMPACT: More daily trips • 1/5 of the trolley use predicted by surrounding sites (and 1/3 of sites with a 10 minute walk to transit) notwithstanding 3 trolley stop access from our site • IMPACT: More daily trips • 13% more single car usage at our site compared to SANDAG estimates at most comparable mixed use site – all coming out of 3 passenger car trips • IMPACT: More daily trips These changes amountallowed to a substantial erroranalytical in trip rates estimated by the –model.

Why Not Just Fix The Model? – Apparently Politics… • We have been trying. We have requested a significant amount of information to help inform SANDAG of errors in our model vs surrounding • Politics is now getting in the way – PER SANDAG’S OWN MODELLER • When asked why there will not be a separate technical meeting (to ensure accuracy), he responded “Politics have forced our hand” How are politics allowed to outweigh analytical integrity at SANDAG – particularly now? $200 m stadium with premier viewing experience and flexible seating from 21, 000 – 32, 000 10 Proprietary & Confidential
