NorthStar’s Environmental  and Planning team has long-standing relationships with regulatory agencies in addition to their in-depth understanding of federal, state, and local laws and regulations. This allows us to help our clients navigate an ever-changing regulatory climate, to obtain permits, or to resolve violations when they occur.

Some questions we can help you answer include:

  • What types of permits or environmental documents do I need to develop my property?

  • Does my property, or a property I am interested in purchasing, have environemntal constriants such as rare plants or animals?
  • What is a SWPPP and when do I need one?
