The Pima County Board of Supervisors approved a development agreement Tuesday with the company that owns the old Hook M Ranch near Corona de Tucson, southeast of Tucson.
Diamond Ventures, which owns the 716 acres, plans a development that will include 1,376 homes, 400 apartments, open space, small commercial spaces and a public school.
The agreement specifies transportation and wastewater improvements that will be required to develop the land, which was rezoned two years ago.
They include designing and extending East Andrada Road from South Houghton Road to the entrance of the proposed project, as well as making any necessary improvements to the intersection of Houghton and Andrada.
The county Transportation Department will conduct a traffic study to determine the extent of the improvements.
The developer will also be responsible for design and construction of any wastewater pump stations and any conveyance lines to the Corona de Tucson Wastewater Treatment Facility, as well as all on-site wastewater improvements needed to serve the development.
The agreement will last for 25 years from the day it is signed.
It’s expected to take several years before construction begins on the site.
