The Norristown Area School board is looking at a preliminary budget that calls for more than $129 million in spending and a real estate tax hike of nearly seven percent in the new school year. As it stands now, the budget has a shortfall of about $5 million because outside funding sources are drying up.  Federal stimulus funding is ending, Montgomery County is not making a $400,000 Payment in Lieu of Taxes for its One Montgomery Plaza office building, and state funding is uncertain, but probably shrinking.
