Julie Lancelle

Julie Lancelle has recently rejoined the Pacifica Land Trust Board after serving many years in Pacifica as an elected official and on volunteer boards, including 2 stints on the City Council (1992-94, 2002-2010). Julie became involved in environmental protection efforts shortly after moving to Pacifica with her family in 1986, participating in Pacifica Citizens Proposal for Route 1, Pacificans for Mori Point, and as a member of the Open Space Task Force and later the Open Space Committee. This work led to helping with the formation of the Pacifica Land Trust in 1991 and advocating for the funding of the Pedro Point Headlands before the Coastal Commission. Later she was able to join the Board of PLT in 1998 and served until 2002, when she went onto the City Council. Julie fought side by side with other Pacificans to defeat various attempts to develop Mori Point in the 1980’s and 90’s. Those efforts were rewarded in the summer of 2000 when the Pacifica Land Trust (with the support of the Trust for Public Land, the National Park Service, and the people of Pacifica) launched the campaign to save Mori Point by raising $100,000 in 2 months in order to help with the purchase costs and show the Park Service and the Trust for Public Land our community’s strong commitment to saving the 109 acre property
