The staff at Tall Tree Engineering have over ten years of combined experience assisting rural developers rural throughout Mendocino County with engineering design and regulatory permitting. Our services include all phases of land improvements from project identification, to land surveying, and design. We have developed relationships with local businesses and government agencies to help you successfully navigate the intricacies of rural development.
Many of our successes have come from working with the California Department of Fish and Wildlife (CDFW) to obtain Streambed Alteration Agreements, otherwise known as 1600 Permits, for our clients. Fish and Wildlife requires that drainage structures such as pond spillways and culverts have adequate capacity for the 100-year storm event frequently when businesses from the cannabis industry, and elsewhere, are gaining the permits for getting a new business off its feet. Our staff can help you prepare the hydrology reports and improvement plans needed to show that your drainage structures have the required capacity and provide you with design strategies if they don’t.
Additionally, we have the ability to provide bathymetric surveys to help you with water rights compliance reporting, determine pond volumes, and decide how to best measure flows for to the State Water Resources Control Board.
Given how rural Mendocino County is, it’s often necessary to build septic systems to treat residential and commercial wastewater, because sewer systems are not present nearby. We provide services that will help you in all phases of your septic system design including: soil prospecting, Wet Weather Percolation & Groundwater Testing, and find the most suitable Onsite Waste Treatment System (OWTS) for your residential or commercial septic system.
When developing or improving property within the unincorporated areas of Mendocino County, the California Building Code requires that a grading permit is obtained when 50 cubic yards or more of earth is excavated, used as fill, or both.

Our staff has the experience needed to effectively work with the County of Mendocino Planning and Building Department to obtain the grading permits required for your earthwork projects. Whether it be residential or commercial buildings, greenhouse pads, roadway improvements, wastewater, agricultural or reservoir design, underground utility trenching, or vineyard development, we you are ready to jump on board and help you to the best of our knowledge and ability.
