What are the organization's current programs, how do they measure success, and who do the programs serve?

Land Stewardship / Liaison Program

Land Stewardship / Liaison Programs. SDMBA Volunteer Liaisons provide direction, education, and hands-on building and maintenance of trails throughout San Diego County. Liaisons work with park rangers, city councils, community groups, and others concerned with maintaining accessible and sustainable recreational trails for our citizenship to provide balanced access for all trail users.

Population(s) Served

Trail Building and Maintenance: Trail work Days are an important element of promoting access to trails by helping to design, maintain, and build sustainable trails for all users. Trail building includes construction of bridges, cutting fresh trails, repairing damaged trails, working around endangered habitats and species, private and military property owners, securing a wide variety of tools, organizing volunteers into workable trained teams, training team' bosses,' developing robust helpful relationships with area Liaisons and agencies, and providing a majority of work during our brief rainy season when trails are most workable.

Population(s) Served

Education and Youth Support: Looking toward the future, SDMBA involves youth through a variety of recreation opportunities intended to further young rider's safety, fun, education, and responsible use of sustainable trails and habitat. Volunteer time equivalencies, transportation, bike purchases for maintaining safe bike stable, insurance, waivers, safety materials, helmets, bike transport, trained /certified instructors, event advertising and PR costs, SWAG and other distributed materials, materials reimbursement all contribute to program operations. Featured Program Opportunities: IMBA Take a Kid Mountain Biking Day, portable pump track at community events throughout the county, Guided family rides and clinics in partnership with Sprockids San Diego and other partners.

Children and youth

Bike Skill Park Complex Development: SDMBA Volunteers, from 2008 to the present, researched and prepared materials to support building a family-oriented Bike Parks with skills / trials areas, jumps, and pump track for the city and its guests of all ages in various locations throughout the County. The Sweetwtater Bike Park and the Greg Cox Bike Park both in the South Bay are very successful in providing a safe place for all riders to practice their skills. Other spaces throughout the San Diego County area are also being explored as options for bike skills parks. Help us promote future bike skills parks for the present and future San Diego families.

Population(s) Served
Children and youth

Bike Bell Program: One of the main concerns of SDMBA, is sharing the trails with everyone. Having a signal for trail users to know that a mountain biker is coming goes a long way to happy sharing of trails. While first started as a way for hikers to let bears know of their presence, bear bells attached to mountain bikes make it very easy for hikers, equestrians, and other bikers to not be surprised by an oncoming mountain biker. This helps everyone have an enjoyable time in nature, helps prevent misunderstandings, and improves safety.SDMBA's first set of bike bells were provided through a generous grant from our friends at REI. SDMBA desires to expand the Bike Bell Program to new locations throughout the county. If you would like to help, SDMBA can always use a few extra funds to buy more bells and build distribution and collection boxes. Bike Bell Stations in San Diego County include Black Mountain, Penasquitos Canyon, Mission Trails Regional Park, and Noble Canyon.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990

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.
