Site Planning & Feasibility in La Plata County
Before you break ground — or even buy the lot — we evaluate topography, utilities, zoning, and access to make sure your La Plata County property is buildable, permittable, and aligned with your budget.
Land Feasibility & Site Analysis
Every buildable lot in La Plata County tells a different story. Elevation, slope, soil composition, and utility proximity all shape what you can build, what it will cost, and how long it will take. Our site feasibility study in La Plata County starts with boots on the ground — walking the property, reading the terrain, and identifying the factors that will drive your project's success or complications.
We perform comprehensive topography evaluations to understand grade changes, drainage patterns, and rock depth across your parcel. For properties along the Animas Valley floor, the challenges are often high water tables and flood plain proximity. On hillside lots above Durango or in the rural subdivisions toward Bayfield, steep grades and access road construction dominate the equation. Our site planning services in La Plata County account for all of it — and we document findings so you have a clear picture before spending on architectural design.
Solar orientation is another factor we assess early. At La Plata County's elevation, passive solar gain can significantly reduce heating costs through long winters. We map sun paths across your lot to identify optimal building placement and window orientation. Combined with our driveway gradient analysis for winter access feasibility, you get a complete land development planning picture for your Colorado property.
Topography & Soil Evaluation
Comprehensive grade analysis, soil stability testing, and rock depth assessment to determine foundation requirements and excavation costs for your La Plata County lot.
Driveway & Access Analysis
Gradient calculations for driveway routes, emergency vehicle access compliance, and winter maintenance feasibility — critical for hillside properties around Durango.
Solar Orientation Assessment
Sun path mapping and passive solar analysis to position your home for maximum energy efficiency and natural light at La Plata County's 6,500+ foot elevation.
Building Envelope Optimization
Identification of the best buildable zone on your property — balancing setback requirements, view corridors toward the San Juan Mountains, and terrain constraints.
Zoning & Land Use Navigation
We interpret La Plata County Land Use Codes for your specific parcel — setbacks, height limits, use classifications, and ADU allowances — so you know exactly what's permitted before you design.
Plot Plan Development
Detailed, scaled plot plans showing building footprint, setbacks, utility routing, and access — prepared to La Plata County's building permit application standards.
Utility Provider Coordination
Direct coordination with LPEA for electrical service, local water districts for tap fees and connection logistics, and gas providers — securing commitments early to avoid timeline delays.
OWTS & Septic Planning
Perc test coordination, system placement mapping against setback requirements, and San Juan Basin Public Health permit guidance for properties not connected to municipal sewer.
Permitting & Zoning Coordination
La Plata County's permitting process has specific requirements that trip up property owners who try to navigate it cold. Zoning districts dictate setbacks, allowed uses, and density. Building permits require compliant plot plans, engineered foundations, and utility service confirmations. Miss a step and you're looking at weeks of delays — or worse, a design that doesn't fit the code.
We develop detailed site plans for permit applications that satisfy La Plata County requirements from the first submission. That means accurate boundary surveys, setback calculations, utility routing, driveway access documentation, and septic system placement — all coordinated before the plans hit the reviewer's desk. We also handle direct communication with LPEA, local water districts, and the county planning department so you're not making phone calls to offices you've never dealt with.
For properties requiring septic systems, OWTS placement and feasibility planning is a critical early step. Perc tests, setback compliance, and health department permits all need to be resolved before you finalize your home's position on the lot. We coordinate this process alongside your custom home building design to ensure the entire site plan works as a unified system.

What Proper Site Planning Prevents
Skipping a site feasibility study is how $300,000 budgets become $450,000 projects. Here's what professional site planning catches before it costs you money.
Hidden Excavation Costs
Rock layers beneath the surface can add $30,000 to $100,000+ in blasting and removal. Our soil and geology assessment identifies this before you commit to a foundation plan.
Utility Connection Surprises
Rural La Plata County parcels can require long utility runs — electrical service extensions, well drilling, or water district tap fees that weren't in your original budget.
Zoning Non-Compliance
Designing a home that violates setbacks, height limits, or use restrictions means redesign costs and permit delays. We verify zoning compatibility at the start.
Access Road Issues
Driveways that exceed county grade maximums won't pass permit review. Steep access also creates winter maintenance challenges that affect daily livability in Durango's climate.
Septic System Constraints
Failed perc tests or inadequate separation distances can make a lot unbuildable — or force expensive engineered septic systems. We test and plan OWTS placement early.
Missed View Potential
Poor building placement wastes your lot's best asset. Our building envelope analysis positions your home to capture San Juan Mountain views and optimal solar exposure.

What Our Customers Say
"Louis Garday, Sr Pagosa Springs, CO 81147 Re: Positive Design - Mark Positiviata December 23, 2025 What I immediately learned when we first started renovating my 4,000 sf log home was that above and beyond everything else, MARK IS A CRAFTSMAN AND PROFESSIONAL in the truest meaning of those words. His work for the planned 10 months was all completed in several diverse areas, on time, on budget, adding a professional flair whenever possible, such that I can easily claim that his skill and craftsman like work on every aspect of the engagement, including concrete and tile work, fine detailed carpentry, building a new 30’ by 20’ TREX deck, electrical work, safety grab bars and plumbing, repairs of metal roof, painting and drywall, landscaping, and a complete home Code evaluation and corrective action. His professional work easily yielded an increase of my home's value at double what I spent on the project. That ROI clearly will show up if/when I sell the house in 2026 or beyond. In a highly confident and in an unqualified manner I strongly recommend Positive Design and Mark to anyone needing all manner of home construction from a true professional and frankly a nice guy. Louis J Garday Sr. More Background information: Sometimes you get lucky. I was introduced to Mark at a dinner in late 2024 and the conversation turned to the details of the multi-faceted work I needed need to renovate and upgrade my 4,000 sf home on ten acres preparatory to selling it in the Spring of 2026 (my best estimate at the time for the optimum timing to sell based on the political/economic chaos brought on by Fed, the then current administration and pending tax law changes during the four years ending in January 2025). I have a lifetime and some 50 years' experience in the construction and real property development businesses, know the trades and have built or developed multiple commercial properties and was impressed with his knowledge during our dinner. The following Monday I received a call from Mark asking if he could walk my property with me and organize my thoughts on what I characterized as extensive work. What followed was a long and detailed survey he compiled of what was needed to remodel and reposition a 30-year-old valuable and custom log home and natural 10-acre landscape of some 200 Ponderosa Pine Trees, surrounded by the San Juan National Forest. Mark made extensive notes and revisited me a few days later, with a detailed proposal, cost estimates, a few new ideas to maximize what I had in place, a time and materials schedule, work timing and scheduling (what us old time real estate guys call a PERT Chart). This being a new relationship and having just met Mark, I agreed to bite off the first phase immediately and Mark began the (bring it up to Code phase) the following Monday in December 2024. Work began immediately and he moved his equipment into my carport and began working. I need not have worried about Mark and the process. He did a great job from Day through the completion.

"Mark remolded our home when we bought it to perfection!!! He built a corner fireplace; a new kitchen with built in cabinet with glass doors and lights for displays. We have the most amazing master bath as he built a round shower stall, walkin with 5 shower heads, a seat and all done in glass bricks. The window is all glass bricks to let the light in with an open small window at the top to let steam out and fresh air in if wanted. A beautiful tile inlaid floor rhat is heated as wanted that he designed. Many people have come to look at it and he built several more!! He comes to fix anything or make something better when ever he is needed. He builds remarkable original things which he designs to fit the space and to last for ever! He is an artist and a very talented guy!!! I would not have anyone else do the kind of work Mark does!! Leslie Hawkinson"

"4.5 stars - Mark Posiviata at Positive Design Build LLC did a beautiful job designing and building my laundry/mudroom. The cabinets, bench, and countertop are absolutely stunning, and the craftsmanship is truly top-notch. The quality of work and attention to detail really show — the space is both functional and gorgeous. Design-wise, Mark was excellent to work with. He listened carefully, offered great ideas/suggestions, and delivered a final result that exceeded my expectations. I’m thrilled with how the room turned out and receive compliments on it all the time. The only area for slight improvement would be communication and coordination with contractors during the process, which could have been smoother at times. That said, the end result was well worth it. I would absolutely recommend Mark and Positive Design Build LLC for anyone looking for high-quality custom work and thoughtful design."

Site Planning FAQ — La Plata County
Answers to the questions we hear most from property owners planning to build in La Plata County and the Durango area.
Frequently Asked Questions
What is included in a site feasibility checklist?
A thorough site feasibility checklist covers utility availability and easement locations, topography and grade analysis, zoning setbacks and building envelope restrictions, and environmental constraints like wetlands or floodplains. In La Plata County, we also assess driveway grade for emergency vehicle access, soil bearing capacity for foundation design, and solar exposure for passive heating potential. Our checklist is specific to Southwest Colorado conditions — we know which issues are common on parcels around Durango, Bayfield, and the county's rural subdivisions.
What are the common La Plata County zoning laws for residential builds?
La Plata County residential zoning typically requires 25-foot front setbacks, 10 to 15-foot side setbacks, and structure height limits of 35 feet. ADU (accessory dwelling unit) allowances vary by zone district — some areas permit them outright while others require conditional use permits. Land use classifications range from Rural Residential to Agricultural, each with different minimum lot sizes and permitted uses. We navigate these regulations daily and can quickly tell you what's buildable on a specific parcel before you commit to a purchase.
How much does a site plan for a permit cost in Colorado?
A standard plot plan for a La Plata County building permit typically runs $1,500 to $4,000, depending on lot complexity and surveyor requirements. Straightforward lots with existing surveys on the lower end, while steep terrain, multiple structures, or properties requiring new boundary surveys push costs higher. We coordinate directly with local surveyors and can bundle site plan preparation into our design-build process, which often reduces the overall cost compared to contracting these services separately.
Why do I need a feasibility study before buying land?
A pre-purchase feasibility study prevents you from buying a lot with hidden construction costs that can derail your budget. In La Plata County, we've seen parcels that look buildable but require $80,000+ in rock excavation, lots where the nearest water tap is a mile away, and properties where septic system placement eliminates half the buildable area. Our site feasibility study in La Plata County verifies buildability, estimates utility connection costs, and identifies grading challenges before you close — so you make the purchase decision with full information, not assumptions.
How does topography affect building costs in Durango?
Topography is one of the biggest cost variables for new construction in the Durango area. Steep lots often require rock excavation or blasting, which can add $30,000 to $100,000+ depending on volume. Significant grade changes also necessitate engineered retaining walls and more complex foundation systems — stepped foundations, caissons, or structural slabs instead of simple footings. We evaluate slope, soil type, and rock depth during our site analysis so you have realistic cost expectations before committing to a design that doesn't fit the terrain.
Can you help with septic system (OWTS) planning?
Yes — septic system planning is a critical part of our site feasibility work in La Plata County. We coordinate percolation tests with certified testers, identify suitable system placement areas that meet setback requirements from wells, property lines, and waterways, and guide you through the San Juan Basin Public Health department permit process. OWTS placement often dictates where your home can sit on the lot, so we address this early in the planning phase rather than discovering constraints after design is complete.
How do driveway grades impact permit approval?
La Plata County requires driveways to meet emergency vehicle access standards — generally a maximum sustained grade of 10% with adequate turnaround space for fire apparatus. Steeper sections may be allowed with specific surfacing and drainage improvements, but winter safety is a real concern at elevation. We analyze driveway gradients during site planning and design access routes that meet county standards while remaining safe and maintainable year-round in Durango's snow and ice conditions.
What is a plot plan vs a site plan?
A plot plan is a scaled drawing showing your lot boundaries, setbacks, and the proposed building footprint — it's the basic document La Plata County requires for a building permit application. A site plan is more detailed, typically including grading and drainage plans, utility routing, driveway layout, septic system placement, and landscaping. Most residential permits in La Plata County require at least a plot plan, but complex lots or properties in certain zoning districts may need a full site plan. We prepare both as part of our land development planning process.
