Project Development Assistance
Sierra Overhead Analytics equips owners, developers, and EPC's with on-time analytics needed to make informed site development choices. Our services provide value for solar PV projects no matter their scale or complexity.
Our comprehensive solar toolkit adds value at every stage of the project lifecycle.
Initial site selection efforts focus on identifying sites with optimal characteristics for solar projects. We analyze public & open-source datasets to identify the highest-ROI development areas.
Once a site has been identified, our team completes initial feasibility studies to determine capacity, complexity, and cost of any future development efforts on the site. Factors accounted for include:
EPA - NEPA, CEQA Regulations
Drainage and Flood Plains
Vegetation and Ground Cover
Climate and Weather
SOA’s typical Critical Investigation Analyses (CIA’s) will give your team a Permitting Matrix and vetted 30% layout for your site, suitable to determine project costs, ROI, and a rough schedule. This will enable you to hit the ground running on a clear development and design pathway.
SOA’s mapping services allow for design and construction of projects on a speedy and accurate basis. We use our advanced toolset to create a complete digital depiction of your site, and can deploy nationwide to do so.
SOA’s expertise in the use of UAS (Unmanned Aircraft Systems) to supplement topographic surveys with aerial data allows us to provide centimeters-accurate coverage of all site features while reducing turnaround time - whether you’re looking at a rooftop, a parking lot, a large greenfield area, or urban-rural mixtures.
SOA teams with a national network of subcontractors who provide boundary / cadastral and underground utility mapping services, allowing for comprehensive satisfaction of information requirements for layout design and AHJ requirements for development.
Turnkey Design & Permitting
SOA is highly experienced at the creation of plan sets for 100kW to 200MW ground-mount PV projects.
Civil and Environmental Engineering
SOA's team of experts fully manage engineering or work with your selected subcontractors to develop your project through all stages of design and permitting to final completion.
Topographic and Boundary Surveys
Structural Designs: Roads, Fences, Racking, & Concrete
Grading Plans and Cut-Fill Analysis of Design Alternatives
Drainage Plans & Stormwater Management
Vehicle Traffic Analysis & Equipment Staging
We are fully CAD- and GIS- capable, allowing us to deliver a plan set rigorous enough for permit applications and understandable enough for painless commencement of construction operations.
Hydrologic and Hydraulic Expertise
We are experts in the turnaround of pre- and post-construction hydraulic modeling services for photovoltaic installations. When combined with highly precise ground data, this assists us in devising:
SWMP (Stormwater Management Plans)
SWPPP’s (Stormwater Pollution Prevention Plans)
Detention and retention basin sizing and design
ESC (Erosion and Sediment Control) plans
Sediment retention basin placement and sizing
SPCC’s (Spill Prevention Control and Countermeasure) plans
Pier and Foundation Hydraulic Modeling
Flow and Scour-Potential Calculations
Sediment Transport Models
Our highly precise analysis of your site prevents potentially catastrophic flood events and removes the the need for over-engineered trenching or swale systems.
Permitting and Negotiation
SOA team members are skilled at working with AHJ’s and local stakeholders to gain quick approval for solar projects. Permits include:
Groundwater Discharge Permits
NPDES & Non-NPDES Stormwater Permitting
USACE Permitting and Jurisdictional Determination support
Septic System & Potable Water System Permitting
Conditional Use Permits (CUP)
Stormwater Discharge Allowances (Quantity and Quality)
Public Notifications and Comment Process
We provide the necessary explanation and justification to all local stakeholders to get them on your team’s side.
Asset Management & PROTECTION
We continue to provide value even after the acceptance of our plan set. Our suite of services has application throughout the construction phase and after closeout.
Scopes of work:
Construction Progress Monitoring (Video-Fly Throughs, 3-D mapping)
IR Panel Thermography
Site Vegetation Monitoring
Forensic Engineering - Racking, Posts, and Concrete
SOA’s designs have been permitted and approved across the country, and our mapping and analysis services are suitable for any-scale ground-mount solar PV project.
Our services have found application across the entire range of renewable energy user roles. Utilities, EPC’s, developers, engineering firms, owners, operators, and manufacturers have all used SOA to add value to their workflows or deliver critical project components.
