Spaceport Camden

Earlier this year, Camden County signed a land-use agreement giving them the option of purchasing a 4,000-acre parcel located at the end of Harriett’s Bluff Road. The county argues that this use of public funding will kickstart the development of Spaceport Camden, a private, vertical rocket launch site and supporting industrial complex.

Although the idea of a Spaceport is exciting, taxpayers in Camden County must remain informed about the project’s potential negative impacts on our environment, fiscal resources, and coastal communities. One Hundred Miles is concerned about how this project will affect our quality of life on the Georgia coast.

Population(s) Served

YELP is a conservation leadership program for high school students who have a strong interest in deepening their environmental knowledge, cultivating leadership skills, and making a positive impact on our coast’s future. YELP provides opportunities for students from across our coast to explore our coastal resources, teaches them the science behind environmental issues, and helps them gain the skills needed to effect change in their communities.

Population(s) Served

Georgia’s 100-mile coast is home to some of the most diverse and species-rich ecosystems on the planet.
Our coastal habitats support 71 high priority animal species and 91 high priority plant species. From the critically endangered North Atlantic right whales, to the nesting loggerhead sea turtles, our coast’s iconic wildlife engage and inspire a new generation of coastal stewards.
OHM celebrates these ongoing efforts by providing opportunities for residents and friends of the Georgia coast to take action in support of our protected species.
1. Educational programming to help residents and visitors understand the simple steps they can take to protect wildlife.
2. Over the past year, we led a community campaign to stop Jekyll Island from weakening their beach lighting ordinance.
3. OHM is a proud member of the Georgia Sea Turtle Cooperative and Georgia Shorebird Alliance.

Balance sheet

Fiscal Year: Jul 01 - Jun 30

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.

Equity strategies

Last updated: 10/26/2023

GuideStar partnered with Equity in the Center - an organization that works to shift mindsets, practices, and systems to increase racial equity - to create this section. Learn more

  • We review compensation data across the organization (and by staff levels) to identify disparities by race.
  • We ask team members to identify racial disparities in their programs and / or portfolios.
  • We analyze disaggregated data and root causes of race disparities that impact the organization's programs, portfolios, and the populations served.
  • We disaggregate data to adjust programming goals to keep pace with changing needs of the communities we support.
  • We employ non-traditional ways of gathering feedback on programs and trainings, which may include interviews, roundtables, and external reviews with/by community stakeholders.
  • We disaggregate data by demographics, including race, in every policy and program measured.
  • We have long-term strategic plans and measurable goals for creating a culture such that one’s race identity has no influence on how they fare within the organization.
Policies and processes
  • We seek individuals from various race backgrounds for board and executive director/CEO positions within our organization.
  • We have community representation at the board level, either on the board itself or through a community advisory board.
  • We help senior leadership understand how to be inclusive leaders with learning approaches that emphasize reflection, iteration, and adaptability.
  • We engage everyone, from the board to staff levels of the organization, in race equity work and ensure that individuals understand their roles in creating culture such that one’s race identity has no influence on how they fare within the organization.
