Grading & Earthwork in Placitas, NM
Mass grading, excavation, embankment, and subgrade preparation for new development — performed under one NM CID license (#385363) to Sandoval County Road Ordinance Section 32-22, terrain management standards, and Public Works inspection requirements at ~6,000 feet elevation.
Grading & Earthwork Built for Placitas Conditions
Placitas sits at approximately 6,000 feet in the foothills of the Sandia Mountains, with significant freeze-thaw cycles, occasional snow, and steep terrain across West Placitas, the Homesteads, and surrounding areas. New residential and access-road projects require precise mass grading, excavation, embankment, and subgrade preparation that meet Sandoval County Road Ordinance Section 32-22 and subdivision terrain management requirements. For paved roads the minimum section is 12 inches of subgrade preparation, 6 inches of base course, and 3 inches of asphalt; driving surface 24 feet with 5-foot shoulders; road grades shall not exceed 8 percent. A state-registered professional engineer must perform construction inspection, materials testing, and compaction tests. As a licensed contractor serving Placitas, we deliver grading and earthwork that meets County Public Works expectations for testing, inspection, and long-term performance at elevation.
12"
Minimum Subgrade Preparation Depth — Sandoval Co. Sec. 32-22
Sandoval County Road Ordinance Sec. 32-22
Before subgrade preparation, all sod and vegetation shall be removed from the road bed. Minimum paved section: 12 inches subgrade preparation, 6 inches base course, 3 inches asphalt surface. Driving surface 24 feet wide with 5-foot shoulders on each side. Road grades shall not exceed 8 percent. Side drainage ditches as approved by the County Engineer. Positive site drainage away from the roadway is required.
Inspection, Testing & Compaction
The developer must retain a state-registered professional licensed engineer to perform overall construction inspection, materials testing, and compaction tests. The developer must notify the Director of Public Works at the start of each phase (clearing and grubbing, compaction, driving surface). Upon completion, a detailed report is submitted to Public Works. Road-cut restoration commonly requires 95% proctor under the road surface and 90% outside.
Terrain Management & Grading Plans
Subdivision plats require a terrain management plan reviewed by the County. Grading plans must show cuts and fills (grades, lengths, depths), areas where natural elevation changes by more than 3 feet, areas of disturbance greater than 1,000 contiguous square feet, methods of stabilization in cut and fill, embankment compaction, and revegetation on steep slopes. Excavated and filled slopes are generally 3:1 or flatter.
Freeze-Thaw, Snow & Foothills Terrain
At ~6,000 feet, Placitas experiences freeze-thaw cycles, snow, intense UV, and monsoon runoff on steep foothills slopes. Gravelly and caliche soils, conglomerate, and slopes of 8–40 percent demand careful moisture conditioning, adequate compaction, positive drainage, and erosion control so finished grades and subgrades resist heave, settlement, and runoff damage.
How Grading & Earthwork Projects Run in Placitas
A clear process designed around Sandoval County Road Ordinance Sec. 32-22, terrain management requirements, and Public Works inspection phases.
Project Scope & Site Evaluation
We review the grading plan, geotechnical data, cut/fill balance, slope limits, drainage requirements, and Sec. 32-22 / terrain management standards, then define the full earthwork scope under our NM CID license.
Design Coordination & Plan Package
Plans address mass grading, embankment, subgrade preparation (12" minimum for roads), slope stabilization, and erosion control. Terrain management and grading plan elements are coordinated for County review.
Permits, Approvals & Pre-Construction
We secure required approvals, confirm the licensed engineer for inspection and testing, and schedule work around development phasing, weather windows, and Public Works notification at each construction phase.
Clearing, Earthwork, Compaction & Testing
Crews clear and grub, excavate and place embankment with controlled compaction, prepare subgrade (12" minimum depth for roads), perform or coordinate materials and compaction testing, and notify Public Works at the start of each phase.
Final Grades, Report & Close-Out
Finished grades are verified to design elevations. A detailed construction report with testing documentation is submitted to the Director of Public Works. Clear handover for subsequent base, pavement, or building work.
Our Albuquerque headquarters is approximately 30–40 minutes via I-25 and NM 165, allowing reliable mobilization and consistent project supervision for Placitas grading and earthwork sites.

What terrain management requirements apply to subdivisions?
A terrain management plan is required for subdivision plat approval. Grading plans must show cuts and fills, areas where natural elevation changes by more than 3 feet, areas of disturbance greater than 1,000 contiguous square feet, methods of stabilization in cut and fill, embankment compaction, and revegetation on steep slopes. Excavated and filled slopes are generally 3:1 or flatter.

How do elevation and climate affect earthwork?
At approximately 6,000 feet, freeze-thaw cycles, snow, intense UV, and monsoon runoff on steep foothills slopes require moisture conditioning, adequate compaction, positive drainage, and erosion control. Gravelly and caliche soils and conglomerate demand careful subgrade preparation so finished grades resist heave, settlement, and runoff damage.

Yes. Patriot Asphalt and Construction holds an active NM CID license (#385363), is bonded and insured, and serves Placitas from our Albuquerque headquarters.
Sandoval County Road Ordinance Section 32-22 sets minimum requirements: 12 inches subgrade preparation, 6 inches base course, 3 inches asphalt for paved sections; 24-foot driving surface with 5-foot shoulders; road grades not to exceed 8 percent. Positive drainage away from the roadway is required.

The developer must notify the Director of Public Works at the start of each phase. A detailed report is submitted upon completion. Road-cut restoration commonly requires 95% proctor under the road surface.
Subdivision plats require a terrain management plan. Grading plans must show cuts and fills, elevation changes over 3 feet, disturbance over 1,000 contiguous square feet, stabilization methods, embankment compaction, and revegetation on steep slopes. Slopes are generally 3:1 or flatter.
At approximately 6,000 feet, freeze-thaw cycles, snow, intense UV, and monsoon runoff on steep foothills slopes require moisture conditioning, adequate compaction, positive drainage, and erosion control so finished grades and subgrades perform before base and pavement are placed.
Duration depends on cut/fill volume, soil and slope conditions, weather, and County review/inspection schedules. After plans and approvals are in place, mid-size residential or access-road grading packages are often measured in weeks. We publish a realistic schedule at contract.
We serve all of Placitas, including West Placitas, the Homesteads, foothills areas, and surrounding Sandoval County communities within our service radius.
