Wetland Delineations, Biological Surveys, Permitting and Geospatial Services as Commercial Drone Service Provider

About Us

Salix Consulting provides wetland, biological and geospatial analyses for many types of projects throughout the western U.S.  Projects typically start with understanding project goals, an analysis of the landscape and existing conditions, putting the resources in regulatory context, and strategically applying methodologies to accomplish the goals of the project. Our emphasis is on clear understanding of issues at hand, collecting, analyzing, and presentation of data, and determining the most effective and efficient path through the process.  We emphasize spatial accuracy through a rigorous data collection process derived from field-experienced observation and the application of GPS/GNSS and small unmanned aircraft systems (sUAS).  The resulting data is used to problem solve and assist with resolving regulatory challenges through the display of understandable and accurate findings. 

Wetland & Biological Services

Salix conducts wetland and biological evaluations to the level of detail necessary for the project.  Often, the only analysis needed is whether or not a property contains wetlands or habitat for a particular special status species.  Typically, a project will require a formal wetland delineation and jurisdictional determination and a biological resources assessment with special status species surveys.  Our approach is to conduct what is necessary but not what isn’t.

Wetland Delineations

Salix conducts wetland delineations in accordance with Corps of Engineers current guidance, applying detailed and defensible methodologies. If a formal wetland delineation is not necessary, a wetland assessment or a wetland determination may provide the appropriate level of detail.


Biological Analysis

Salix conducts biological analysis to meet the needs of a project. Plant and animal assessments are typically assessed at the same time, and a Biological Resources Assessment document is written. Special-status plant and animal surveys may follow depending on findings and project details.



Salix prepares permit application packages that meet the requirements of Sections 404 and 401 of the Clean Water Act, the Porter-Cologne Water Quality Control Act, the California Department of Fish & Game Code (Sections 1602 and 2081), and U.S. Fish and Wildlife Service Sections 7 and 10 consultations, including Alternatives Analyses, and mitigation and monitoring plans for wetland and biological impacts.



Our International Society of Arboriculture (ISA) certified arborist conducts tree evaluations and inventories based on local ordinances or other guidance. Certified Arborist Reports are prepared and include recommendations for effective tree management. Salix can assist with tree impact permits as needed.


Geospatial Services

Salix offers a complete geospatial service package from aerial mapping, data processing, and spatial analytics with final outputs seamlessly incorporated into Geographic Information Systems (GIS), Computer Assisted Drawing (CAD) programs, and web based visualizations. As FAA Part 107 Certified Remote Pilots we specialize in aerial based mapping on projects and landscapes of any scale, leveraging incredibly rich data sets with spatial analysis, empowering our clients to make more informed decisions.

FAA Part 107 Commercial Drone Service Provider

Aerial Mapping and Data Processing

Salix specializes in aerial mapping projects of any scale with multi-rotor and fixed-wing drones. When projects reach a scale where drones are no longer feasible, we utilize piloted aircraft. We produce high resolution and spatially accurate outputs including seamless aerial orthomosaics, point clouds, terrain models, contours, and 3D meshes in the visible and near-infrared light spectrums. Salix also provides data processing services for clients electing to collect their own imagery.


Aerial Photography and Video

Salix provides professional aerial photography and video services. Imagery services include aerial obliques, 360-degree aerial panoramas, and properly scaled 3D objects inserted into imagery. Our video services include project fly throughs, orbits and 3D objects (e.g., proposed project design) in video. Our imagery and video services can be customized to clients end needs and preferences including editing, branding and web hosting.

Geographic Information Systems (GIS) and Analytics

Geographic Information Systems

Salix provides Geographic Information Systems (GIS) services. Effective organization of spatial data allows for a greater understanding of a projects relationship spatially to the bigger picture and ultimately makes for more informed decision making. GIS is a central component to our problem solving framework.


Spatial Analytics

Salix applies spatial analytics to tackle complex problems. Robust datasets such as those collected and processed from drone imagery are further leveraged through analytic pipelines in GIS software to gain an even deeper understanding of your site or project. Common analytics include terrain analysis, hydrologic modeling, site suitablity and assessment, viewsheds and solar irradation models.


Mapping and Cartographic Services

Mapping services are conducted with high accuracy GNSS receivers. Where a licensed surveyor is not required, we provide cost effective and accurate solutions to your spatial mapping needs.Our cartographic services make complex datasets suitable for print or publication.


Web Visualization and Hosting

Salix provides web visualization and hosting services to interact with your spatial data online. These web maps are lightweight and embeddable making them well- suited for sharing data across your organization, website or blog. These maps can host infinitely large datasets eliminating your need for specialty software and computers as all the heavy lifting is done behind the scenes. These are especially effective in displaying very large and robust datasets such as those processed from drone imagery.
