Extraordinary changes in land use development took place in Contra Costa County during the 1960's and helped lead to Save Mount Diablo's formation on December 7, 1971, during the rapid expansion of the environmental movement following the first Earth Day.
Public perception at the time was that the State Park included the entire mountain. The truth was the State Park stood alone at the summit and down to Rock City, a solitary 6,788 acres. Except for the drive to the summit, you could not easily get into the Park. None of the low elevation staging areas or trails existed, none of the city or regional open spaces had been created, and local environmentalists became increasingly alarmed as subdivisions started creeping up to the mountain's foothills. A flashpoint in these applications was the Scott development at Walnut Creek's Shell Ridge.
At meetings of local conservation groups Dr. Mary Bowerman,
a student of the mountain's botany since 1930 and author of The Flowering
Plants and Ferns of Mount Diablo, California, would rise to ask "What
can we do to help save Mount Diablo." Finally Arthur Bonwell, Chairman
of the Mount Diablo Regional Group of the Sierra Club, responded, "why
don't we start a group to focus on expanding the State Park?" Bowerman
provided the inspiration, Bonwell helped get things organized, and on
December 7, 1971 a first meeting was held.
SMD was initially made up of representatives from organizations--city recreation commissions, hiking, biking and horsemen's clubs, an archery club, the AAUW, the Sierra Club, the Contra Costa Park Council, etc.--whoever it was thought might have an interest. The initial goal was to protect and preserve Mount Diablo, primarily by pushing for legislative attention and state park bond acts. It was decided to maintain a narrow focus on the mountain and to avoid other issues.
From the beginning, Save Mount Diablo responded to
development applications, beginning with the Morgan Territory Estates
project and the proposal for Blackhawk, seeking to stop development or
preserve sensitive areas as a condition of its approval.
Before long, SMD decided that one of the best ways to spur acquisition would be to help raise money to acquire land. In 1976 the group made its first acquisition, 117 acres at the corner of Marsh Creek and Morgan Territory Roads, strategically expanding the State Park to the northeast.
Also from the beginning, Save Mount Diablo worked with other organizations and agencies to achieve its goals. It aided and encouraged the East Bay Regional Park District and various cities as they began creating preserves in the mountain's foothills. By the 1980s the group's focus had expanded from simply park expansion to secondary goals of the creation of wildlife and recreational corridors connecting the various parks.
Park management is a secondary goal for the group, but Save Mount Diablo has weighed in on many policy issues, including grazing and the removal of communication towers. It has built and sponsored a variety of recreational projects, such as the repair of picnic areas and the creation of campgrounds, and has restored habitat and species such as the endangered peregrine falcon. SMD's Board of Directors has gradually expanded the organization's Area of Interest as parks expanded and the group's capacity increased.
In 1980 SMD incorporated as a non-profit corporation. Over the years, SMD's 'representative' structure boiled down to a committed Board of Directors. In 1988 the group hired its first staff and in 1996 opened its first office. From a membership of 1,000 supporters in 1988, by 2001 the group included 6,000.
From a single park and 6,788 acres in 1971, high on
the mountain's slopes, today forty parks and preserves are found on and
around Mount Diablo, stretching from Walnut Creek to Brentwood and Livermore,
totaling more than 100,000 acres. Meanwhile, co-founder Arthur Bonwell continues as an active member of the Board of Directors
of Save Mount Diablo.
2010: Three more properties were acquired: Dry Creek – 5 acres near Brentwood, Oak Hill – 40 acres between Viera and Wright Canyon, and a 20 acre property along Morgan Territory Road. The Irish Canyon property was transferred to the EBRPD with the help of the ECC Habitat Conservancy. The stewardship committee, guided by the newly hired Stewardship Coordinator, planted oaks and built trails on Irish Canyon and tended to some 500 natives that were planted on Marsh Creek IV. PG&E helped out by donating a pick-up truck to haul tools, materials, trash and sometimes event supplies. There were two efforts to change the voter-approved Urban Limit Line: Measure F in Brentwood and Measure W in San Ramon (threatening the Tassajara Valley). SMD teamed up with local residents and other environmental groups and defeated both measures. SMD was one of the major supporters of Proposition 21, the State Park Access Pass. The defeat of this measure means less funding for Mount Diablo State Park’s operations and maintenance. SMD successfully finished its first capital campaign to raise the funds needed to preserve Viera – North Peak forever.
2009: We finalized acquisition of Marsh Creek - IV, 2.65 acres including a stretch of Marsh Creek and a connection to another protected property. Our most important acquisition of the year was signing a purchase agreement for the Viera property, 165 acres on the slopes of Mt. Diablo’s North Peak - a high priority since 1971. Viera is one of the highest points in the East Bay at 2,300 ft. and is inhabited by over 50 rare plants as well as unique and threatened animals. We increased our stewardship program involving hundreds of volunteers in 21 restoration projects on our properties including creating a new trail with the help of East Bay Trail Dogs and the REI – Brentwood store . Grants from REI and the HEDCO Foundation allowed SMD to purchase an Off-road Utility Vehicle to assist. We monitored 35 different weekly planning agendas and responded to 42 development projects around Mt. Diablo - from cell tower proposals all the way to the Los Vaqueros reservoir expansion. In four different projects, SMD defended against attempts to develop or encroach upon homeowner open space. As a part of the Community Coalition for a Sustainable Concord, SMD helped preserve a minimum of 3,200 acres of parks and open space from the Concord Naval Weapons Station reuse. As a member of the Save Our State Parks coalition, SMD helped block the closing of over 200 state parks, including Mt. Diablo. Applications were withdrawn for 4 subdivisions – totaling 1,102 acres of rolling grassland in the Tassajara hills. These projects would have lead to fragmentation of wildlife habitat and corridors, while also impacting East Bay Regional Park District’s planned park. SMD formed a coalition to defend the Tassajara Valley from development threats outside of the Urban Limit line. Our first 50K run had 50 participants and rave reviews. The BayWood Artists captured Mt. Diablo in a year’s worth of paintings for a grand exhibit benefitting SMD’s land programs.
2008: SMD has protected six parcels (through acquisition and land use planning) totaling 399 acres. In addition we are about to transfer our 333 acre Chaparral Spring property to East Bay Regional Park District so that it can be opened to the public. We closed negotiations on additional properties in the Marsh Creek area including the 17 acre Marsh Creek II and the 2.65 acre Marsh Creek IV property. We helped stop two attempts to break Urban Limit lines and have responded to 42 other development applications. SMD was one of the three largest donors to support the passing of Measure WW in Alameda and Contra Costa County. Measure WW includes about $65 million for land acquisition and recreation facilities around Mt. Diablo. In stewardship, we managed to work on 37 work projects on properties including building four new trails, repairing a pond, installing 3.5 miles of fencing and beginning oak restoration at Irish Canyon. Another great reason why preserving open space is beneficial was the discovery of two new wildflower species at Lime Ridge in Walnut Creek including the Lime Ridge navarretia and the Lime Ridge woollystar.
2007: In 2007 Save Mount Diablo closed escrow on Irish Canyon and Marsh Creek-I, preserving a total of 537 acres. The volunteer map committee worked for two years to produce the most accurate trail map of Mt. Diablo, Los Vaqueros and Surrounding Parks featuring the Diablo Trail. The map features 250,000 acres (90,000 of which are protected), and 520 miles of public trails highlighting the 30 mile Diablo Trail. Funding was provided by REI. SMD completed 42 work projects on our properties in an effort to clean up and restore the natural habitat and create recreational opportunities consistent with protection of those natural resources. We conducted BioBlitz on Irish Canyon and together with 16 volunteer scientists and experts counted 297 species in a 24-hour period. On Mangini we undertook a trash removal project, built fencing around sensitive habitat to protect and allow natural restoration. We installed a monument on Mangini in appreciation of the Mangini Family’s help in preserving the Ranch. The East Bay Trail Dogs helped build new trails on Chaparral Spring and Mangini and maintained trails on Young Canyon. Two board members were honored for their extraordinary volunteer efforts: Scott Hein, was awarded the Threads of Hope award from Diablo Magazine and Don de Fremery was awarded the Oliver Kehrlein Award given by the National Sierra Club.
2006: SMD completed the Mangini Acquisition with the help of Gary Bogue, EBRPD Walnut Creek Open Space Foundation and numerous donors. Other acquisitions included purchasing the 18 acre Young Canyon property, completion of the Gateway Conservation Easement, and signing the purchase agreement for Irish Canyon . “Speak of The Devil: The Unexpected Landscape of Mount Diablo” is published as an educational guide about Mt. Diablo, and supplement to Bay Nature magazine. SMD assisted with the passage of Proposition 84 to provide $5.4 billion for water quality and land conservation, and passage of Measure L to create a county urban growth boundary that will be in effect for 25 years. We also helped to successfully oppose Prop 90.
2005: The 33 acre Brandt property, part of the canyon adjacent to SMD’s Wright Canyon, was preserved. In Alamo, 62 out of 100 acres are preserved when the 39 unit Humphrey project is proposed, including funding for preservation of 193 additional acres. SMD takes over sponsoring the Mount Diablo Challenge, a 10+ mile cycling race to the summit. All of the funding has been raised for the 36 acre property at the State Park's Northgate entrance -- a visual, recreational and wildlife corridor gateway to the mountain. On April 26, the Contra Costa County Planning Commission approved a redesign of the 221 acre Fox Ridge Manor project at the corner of Cowell Ranch State Park. 211 acres are being preserved, including the flood plain of sinuous Briones Valley creek. We started the acquisition process of the historic 207 acre Mangini Ranch adjacent to Lime Ridge Open Space. The Mangini Ranch contains the headwaters of Galindo creek, a beautiful oak woodland bowl filled with rare plants. SMD ended the year by relocating to a larger office space enabling it to work more efficiently with staff and in office volunteers. The Mt. Diablo Buckwheat is rediscovered after being presumed extinct for almost 70 years. Sadly, SMD Co-Founder Dr. Mary Bowerman passed away in August of 2005.
2004: Ended 16 years of work to preserve the more than 3000 acre Riggs Canyon, when the 232-acre Jones property at the canyon mouth was protected with a conservation easement. Fundraising was completed for the 36 acre Gateway property easement- $1.56 million. We aided EBRPD in additions of 160 acres (Shapell-Elworthy) to Morgan Territory Reg. Preserve; 320 acres (Ennes) to Black Diamond Mines; and 617 acres (Souza) to Vasco Caves. We reached agreement with Lemke Company and Clayton over the Claretian Seminaries site, with a dedication to Mt. Diablo State Park and a major precedent, removal of an existing house to restore the Mt. Diablo Creek corridor. The 4000-unit Sand Creek Specific Plan (FUA#1) in Antioch was tabled. SMD supported Measure J, the successful renewal of the County's transportation sales tax, with major environmental components and requiring cities to adopt voter-approved Urban Growth Boundaries like the County's Urban Limit Line. Our 33rd Anniversary, Moonlight on the Mountain, raised more than our goal of $100,000 net; we honored Bob Duchi and Stephen Joseph with Mountain Star awards. Our events schedules included more than 120 hikes and other events celebrating the mountain. We received a grant from REI to publish a new trail map including the Diablo Trail and mapped a route for the 60 mile "Diablo Grand Loop," which will be possible if two small areas are preserved. We began leading hikes at the new 4,000 acre Cowell Ranch State Park, where 5,000 houses had been proposed. State budget cuts closed Diablo's Summit Museum and threatened the State Park; the Summit Museum was reopened. We completed histories regarding Walter P. Frick, who once owned much of the west face of Mt. Diablo; the preservation of Riggs Canyon; and the eye of Diablo, the summit beacon.
2003: In January SMD acquired the 20 acre Morgan Red Corral and the 63 acre Joseph Galvin Ranch. With the Mt. Diablo Gateway Alliance, the group had largely secured funding to acquire a conservation easement at the Gateway property. Cowell Ranch State Park was dedicated in May, and a monument to Jeremiah Morgan at the Red Corral in June. In July SMD's 427-acre Silva Ranch was added to Mt. Diablo State Park along with a new Tassajara Creek trail. SMD opposed the Los Vaqueros expansion ballot item. SMD added a fourth staff person to help with events and fundraising.
2002: More than 4,000 acres were added to Diablo preserves, including sensual 3,647 acre Cowell Ranch State Park, nearly completing a grassland, ridgeline corridor from Los Vaqueros to Black Diamond Mines. The Newry dedication added 184 acres to Black Diamond as an extension to the Ridge Trail there. A Montecito staging area and dedication was added to Lime Ridge at the old Sand Quarry. Two Seeno projects were stopped in Pittsburg and the company was penalized for violating the Endangered Species Act-including preservation of Seeno's 640 acre Morgan Territory Ranch and a $1 million fine. SMD continued opposition to FUA#1 and the County Open Space funding measure. In 2002 SMD expanded its Area of Interest to include the lands around Altamont Pass. Five peregrine falcon chicks fledged at Diablo.
2001: On December 10, 2001 SMD celebrated its 30th Anniversary. EBRPD honored the organization and its founders by naming the crest of Highland Ridge in Morgan Territory as “Founders Ridge." In 2001 it helped secure additional acreage at Highland Ridge, and acquired the Wright/Curry property, to provide a new entrance to the State Park from the east. Its land use efforts resulted in an addition to Lime Ridge Open Space. It helped the Trust for Public Land in fundraising efforts at Cowell Ranch and continued efforts related to a Contra Costa East County Habitat Conservation Plan, Tassajara development, Future Urban Area #1 and Roddy Ranch in Antioch, and the Montreaux project in Pittsburg.

1999: SMD acquired the Silva Ranch, negotiated an 1123 acre easement at Roddy Ranch, extending preserved open space four miles toward Round Valley, and helped acquire and fund Turtle Rock Ranch. Its work resulted in the final Blackhawk dedication in the Blackhills, Oyster Pt. Area. It supported expansion of Brushy Peak, helped fund Clayton Ranch and helped secure additions to Diablo Foothills and Round Valley.
1998: Co-founder Mary Bowerman received Contra Costa County's "Women of Achievement Hall of Fame" award. SMD established new acquisition priorities including an expansion of its focus to include several new areas. It helped preserve Garaventa, the hole in the doughnut at Black Diamond Mines and a former proposed landfill site; negotiated a dedication at Athenian School and aided the EBRPD in the funding to acquire the first part of 1,030 acre Clayton Ranch. It also negotiated significant open space preservation along the Las Trampas to Mt. Diablo Regional Trail.

the State Parks Commission State Park System 1980 Plan, opposed urbanization
of Morgan Territory and development of the Newhall property (Lime Ridge),
and supported down zoning in the Tassajara Valley. It supported the 1980
State Bond Act and urged recreation at the proposed federal Los Vaqueros
reservoir. Its land use efforts led to the first of the Black hawk dedications
of the Blackhills in the vicinity of Southgate Rd., Dan Cook Canyon, Wall
Point, and Jackass Canyon, the largest dedication to that point to the
State Park system, increasing the state park's size by nearly 25%.
1979: SMD opposed Bogue Ranch in Alamo and worked with EBRPD on a later dedication, responded to Pine Hollow and Clayton developments, and gained improvements in the new County Quarry Ordinance. It opposed PG&E high tension lines through Black Diamond and the State Park, resulting in their relocation outside of the Preserve.
