Parking Lot Striping in Sherman County, Oregon
Sherman County is one of Oregon's smallest counties by population, with roughly 1,700 residents spread across 831 square miles of rolling wheat country south of the Columbia River. The county seat of Moro and the small communities of Rufus, Wasco, Grass Valley, and Kent make up virtually the entire settled area. Despite its tiny population, Sherman County has meaningful commercial pavement to maintain — government facilities, grain elevators, school campuses, wind energy operations, and the I-84 corridor businesses at Biggs Junction and Rufus that serve interstate traffic.
The high plateau climate brings intense wind, UV exposure, extreme temperature swings, and dry conditions that challenge parking lot paint in ways unique to north-central Oregon. Cojo provides parking lot striping throughout Sherman County.
Wheat Country Climate and Paint Challenges
Sherman County sits on the Columbia Plateau at elevations ranging from about 200 feet along the Columbia River to over 3,000 feet on the southern plateau. The defining climate factor is wind. The Columbia Gorge funnels powerful westerly winds through the county, and the open plateau landscape offers no natural windbreaks. This constant wind drives dust and grit across pavement surfaces, physically abrading paint at a rate far exceeding sheltered locations.
The wind also accelerates surface drying, which can cause paint to dry too quickly during application and reduce adhesion. Contractors must account for wind speed when scheduling — optimal application requires wind under 15 mph.
UV exposure on the plateau is significant, with clear skies and high elevation combining for 20 to 30 percent more UV than the Willamette Valley. Temperature extremes range from summer highs above 100°F to winter lows well below zero, adding freeze-thaw stress to painted surfaces.
Most Sherman County lots need re-striping every 12 to 16 months due to wind abrasion and UV degradation. Solvent-based traffic paint is the minimum recommendation.
Key Areas Needing Striping in Sherman County
Moro
Moro is the county seat with approximately 330 residents. The Sherman County Courthouse and associated government offices along Main Street are the primary commercial pavement in town. The Sherman County School District campus includes school lots needing student drop-off zones, bus staging areas, and staff parking. The Moro City Park and community center draw local event traffic.
Government facility lots must maintain ADA compliance regardless of community size. The courthouse parking needs proper accessible spaces, signage, and access aisle markings.
Rufus
Rufus sits along the Columbia River on I-84, making it Sherman County's most visible commercial location. The I-84 interchange at exit 114 serves travelers with a gas station, convenience store, and river access parking for windsurfers and boaters who use the Columbia River. John Day Dam is nearby, and the Army Corps of Engineers visitor facilities generate tourist traffic during summer months.
Rufus lots are exposed to full Gorge winds with no shelter, making them among the harshest environments for parking lot paint in the entire state.
Biggs Junction
Biggs Junction at the intersection of I-84 and Highway 97 is Sherman County's busiest commercial location despite being unincorporated. The junction serves as a critical stop for interstate travelers and truck traffic heading south toward central Oregon. Truck stops, gas stations, restaurants, and rest areas at this interchange see constant vehicle flow and need durable markings that withstand heavy truck traffic and extreme wind exposure.
Grass Valley, Wasco, and Kent
The interior plateau communities of Grass Valley, Wasco, and Kent are small agricultural towns with grain elevators, farm supply businesses, and basic community services. Commercial pavement is limited to a few lots per town, but what exists needs maintenance. Grain elevator lots see seasonal heavy truck traffic during harvest and need durable markings for truck staging and loading areas.
Wind Energy Facilities
Sherman County is one of Oregon's leading wind energy counties, with hundreds of wind turbines across the plateau. Wind farm operations and maintenance facilities have employee parking lots, equipment staging areas, and access road turnarounds that need standard commercial striping. These remote sites require travel coordination and are most efficiently served when combined with other Sherman County work.
ADA Compliance in Small Communities
ADA requirements apply fully in Sherman County regardless of community size. Every public-facing parking lot must provide accessible spaces per the Oregon Structural Specialty Code — one accessible space per 25 total spaces, with at least one van-accessible space with an 8-foot access aisle. Signage must be mounted at 60 inches minimum height.
In communities this small, a single business or government facility may be the only option for essential services. Maintaining ADA-compliant parking is not just a legal requirement — it is a practical necessity for residents with mobility limitations who have no alternative locations to access services.

Best Time to Stripe in Sherman County
The optimal window runs from mid-May through mid-October. However, wind conditions must be monitored daily — the Gorge winds can exceed 30 mph on any given day, making application impossible. The calmest conditions typically occur during early morning hours before afternoon winds build.
Summer provides the warmest, driest conditions, but mid-summer heat requires early morning application before pavement temperatures exceed 110°F. Spring and early fall offer the most comfortable working conditions when wind cooperates.
Coordinate all pavement work using a maintenance checklist to maximize value from each site visit.
Frequently Asked Questions
How often should Sherman County parking lots be re-striped?
Wind abrasion and UV exposure mean most Sherman County lots need re-striping every 12 to 16 months. Lots at Biggs Junction and Rufus with direct Gorge wind exposure may degrade even faster. Solvent-based or thermoplastic markings extend intervals. See the complete striping guide.Does the wind affect when striping can be applied?
Yes. Paint application requires wind speeds under 15 mph for proper adhesion and line quality. On the Columbia Plateau, this often limits work to early morning hours. Cojo monitors wind conditions and schedules accordingly. Contact us to discuss scheduling.What paint type handles wind abrasion best?
Thermoplastic markings resist wind-driven grit abrasion better than any paint product. Solvent-based traffic paint is the next best option. Water-based latex paint will be scoured by wind-blown dust and is not recommended for exposed Sherman County lots.Can multiple Sherman County properties be scheduled together?
Yes, and this is strongly recommended. Grouping Sherman County work into a single trip reduces travel costs for all property owners. Cojo coordinates county-wide scheduling to serve multiple sites efficiently.Should I combine sealcoating and striping?
Absolutely. For remote locations, combining services in one mobilization provides the biggest cost savings. Sealcoating is applied first, cures for 24 to 48 hours, then striping is applied. See the sealcoating and striping package.Get Sherman County Striping Scheduled
