The anti-arena group's petitions have been turned in.

The pro-arena group's petition removal forms have been turned in.

So what's next? Here are some details on what's happening and what will happen moving forward as it relates to Sacramento's proposed downtown arena.

Should the project proceed as planned (and there is no reason to believe it won't at this point), a draft environmental review of the arena is expected to be available soon. It is looking like the city council would vote on the final environmental review document in early April. Everything would become binding at that point in terms of the financing, and demolition could begin in June, followed by the first phases of construction in September/October.

The New Coalition

Mayor Kevin Johnson announced Thursday the creation of a new coalition called The4000 as a response to the S.T.O.P. group. The coalition will advocate for the downtown arena and the 4,000 jobs it is projected to create.

Via The Sacramento Bee:

S.T.O.P. received $100,000 from Chris Hansen, the hedge fund manager from Seattle who tried to purchase the Kings and turn them into the Seattle Sonics earlier this year, which, in turn, helped the group collect a large majority of its 35,000+ signatures.

UPDATE

34,000 of S.T.O.P.'s signatures were delivered the county to be validated, via The Sacramento Bee (yep, 1,300 less than had been originally reported to have turned in). The city clerk has requested that each signature be evaluated, rather than using a sample size.

The price to the city to verify all the signatures? $100,000.

S.T.O.P. says they aren't going to come up with money to pay for the validation, according to the Bee.
