Details

From the November 9 committee meeting (auto-captions, figures as stated): Public Works said the city required the developer to extend water and sewer at no reimbursement, limited drinking-water use to domestic needs and asked for closed-loop cooling; a sewer pump station is required. The developer described setbacks and berms, covering the utility's grid upgrade costs, offering land for a future widening of East Rice Street, and a preliminary tax estimate for a fully built 500 megawatt campus (about 5 million dollars a year in municipal electricity taxes), which it invited an independent review of. The developer has not built an operating data center. Local engineering firms and trade unions spoke in support; neighbors, including residents outside city limits, asked for a moratorium and raised noise, water, traffic and health questions.
