The Tortolita Alliance (TA) was formed in the fall of 2019 in response to a proposal by the Town of Marana (Marana) and Arizona State Land Department to reconfigure and rezone the Tortolita Preserve (TP).
TA started with 5 Dove Mountain residents and quickly grew to over 350 members. We attended Planning Commission and Town Council meetings in force and were able to convince Marana that TP is one of its greatest assets and should be conserved. Accordingly, the Make Marana 2040 General Plan was adjusted and TP is protected.
The founders of TA agreed that we could not let this happen again and we decided to continue our work as an official group. On January 31, 2020, TA obtained certification as an Arizona Non-Profit Corporation.
We now have 7 Board members with a wide variety of expertise including engineering, science, education, finance, law and communication.
We are fortunate to have such an energetic and collaborative group. Please meet the TA Board of Directors and Officers!
