The alter ego doctrine can be applied to municipal corporations if the factors allowing the doctrine’s application to private corporations are satisfied. Here, plaintiff alleged sufficient facts to show it would be inequitable to recognize the Reclamation Authority’s separate existence since that City formed the Authority specifically to avoid liability for remedying the environmental pollution on the site the City enticed plaintiff to contract for and for whih plaintiff advanced considerable funds. The complaint adequately alleged that the City deliberately underfunded the Authority so it couldn’t complete the remediation needed before plaintiff could build the improvements it had contracted to build on the site.
