On mission with City’s goal to support the growth of the high tech sector in Homer as well as Education and Marine Trades goals.
GOAL: Enhance economic development
in Homer through the education sector.
Support expansion of educational
programs to take advantage of
emerging economic opportunities and/or
to capitalize on Homer’s existing
strengths and assets, such as interest in
sustainability, proximity to ocean
resources, and arts/culture.
GOAL: Support Growth of
High Tech/Internet Businesses
Market Homer’s quality of life
factors and suitability for high-
tech/Internet-based operations.
GOAL: Promote growth and
vitality of the marine trades as
an economic cluster in Homer.
