We can meet on site if needed.Thanks, Ron From:Josh Rice<josh@woodycreekengineering.com> Sent: Saturday, February 22, 2020 2:14 PM To: Ron Christian <ron.christian@cityofaspen.com> Subject: 630 W Hopkins Remodel and Increased Electrical Service Demand Hi Ron, I'm working on a major remodel of 630 W Hopkins. Thus far,the design team has assumed that the new home will require an 800 amp service. Can you identify the transformer currently serving the home and let me know if it has capacity to serve the increased demand. Do you need any other documentation? Thank you, Josh Rice, P.E.
