How long does a commercial paving project take?

Most commercial parking lot paving projects in Oregon take 3-10 days for actual construction, depending on lot size and complexity. However, the full project timeline from planning to completion is typically 6-12 weeks when you include site assessment, permits, contractor bidding, scheduling, and weather contingencies.

Do I need a permit to repave a commercial parking lot in Oregon?

In most Oregon cities, resurfacing an existing lot with the same footprint does not require a building permit. However, changing the lot layout, adding square footage, or altering drainage patterns typically does. ADA upgrades, stormwater modifications, and utility work always require permits. Check with your local jurisdiction before starting.

What is the best time of year for commercial paving in Oregon?

The ideal paving season in Oregon runs from May through October when temperatures are consistently above 50 degrees Fahrenheit and rain probability is lowest. Asphalt plants in the Willamette Valley typically operate April through November. Plan your project for this window, and schedule 2-3 months ahead during the busy summer season.

How do I budget for a commercial paving project?

Budget $3-$7 per square foot for standard asphalt installation, $5-$12 for concrete, and $1.50-$3.50 for resurfacing. Add 10-15% for contingencies (unexpected base repairs, drainage work, weather delays). Include striping ($1,500-$5,000), signage ($500-$2,000), and stormwater management if required by local code.

Should I repave or overlay my parking lot?

Overlay (resurfacing) works when the existing base is structurally sound with less than 25% alligator cracking or base failure. If the base has widespread failure, water damage, or insufficient thickness, full removal and replacement is necessary. A core sample test (drilling into the pavement to check layers) confirms which approach is appropriate.

Planning a Commercial Paving Project: Step-by-Step Checklist

Why Planning Makes or Breaks a Commercial Paving Project

A commercial paving project that goes smoothly is one that was planned thoroughly before a single piece of equipment showed up on site. A project that goes badly almost always has the same root cause: insufficient planning.

Rushed projects lead to missed permits, unexpected costs, poor scheduling during Oregon's limited dry season, and results that do not hold up. Taking 4-6 weeks to plan properly saves you money, headaches, and a parking lot that fails prematurely.

This checklist walks you through every step of planning a commercial paving project, from initial assessment through project completion.

Phase 1: Assessment and Goal Setting (Weeks 1-2)

Define the Project Scope

Before contacting contractors, clearly define what you need:

[ ] Identify the problem. Is this maintenance, rehabilitation, or full replacement?
[ ] Measure the area. Calculate total square footage of the project area
[ ] Document current conditions. Photograph all damage, drainage issues, and problem areas
[ ] List must-haves vs. nice-to-haves. Separate essential repairs from optional upgrades
[ ] Determine if layout changes are needed. Adding spaces, changing traffic flow, ADA upgrades

Assess the Existing Pavement

Understanding what you are working with determines the right approach:

[ ] Surface condition: Rate the severity of cracking, potholes, and surface deterioration
[ ] Base condition: Look for signs of base failure including alligator cracking, heaving, and depressions
[ ] Drainage performance: Note any areas with standing water or poor drainage
[ ] Pavement age: Check original construction records if available
[ ] Previous repairs: Document patches, overlays, and other past work

If you are unsure whether to overlay or replace, request a core sample analysis. A contractor drills 4-inch cores at several locations to measure pavement thickness and assess base condition.

Set Your Budget Range

Establish a realistic budget before soliciting bids:

| Project Type | Cost Range (per sq ft) | 10,000 sq ft Lot | |-------------|----------------------|------------------| | Sealcoat + crack seal | $0.20-$0.50 | $2,000-$5,000 | | Overlay (resurfacing) | $1.50-$3.50 | $15,000-$35,000 | | Mill and overlay | $2.50-$5.00 | $25,000-$50,000 | | Full replacement | $3.00-$7.00 | $30,000-$70,000 | | New construction | $4.00-$9.00 | $40,000-$90,000 |

Add 10-15% contingency for unexpected conditions discovered during construction. Budget separately for striping, signage, landscaping, and stormwater work.

Phase 2: Permits and Compliance (Weeks 2-4)

Check Permit Requirements

Contact your local building department to determine what permits are needed:

[ ] Building permit for new construction or significant modifications
[ ] Grading permit if earthwork exceeds local thresholds
[ ] Stormwater permit if altering drainage or adding impervious surface. See our stormwater management guide.
[ ] Right-of-way permit if work affects public sidewalks, roads, or utilities
[ ] Environmental permits for projects near wetlands, streams, or protected areas

Verify ADA Compliance

Any alteration that affects the parking lot's usability triggers ADA requirements:

[ ] Calculate required accessible spaces based on total lot capacity
[ ] Verify accessible route from parking spaces to building entrance
[ ] Check slope requirements (max 2% in any direction for accessible spaces)
[ ] Plan signage including post-mounted signs and pavement markings
[ ] Identify van-accessible spaces with wider access aisles

Review Stormwater Requirements

Oregon cities along the I-5 corridor have specific stormwater management standards that may apply to your project:

[ ] Determine if your project triggers stormwater requirements (varies by city)
[ ] Identify required best management practices (bioswales, detention, treatment)
[ ] Budget for stormwater improvements if required
[ ] Plan for erosion control during construction

Phase 3: Contractor Selection (Weeks 3-5)

Solicit Bids

Get at least three written bids from qualified paving contractors:

[ ] Request detailed written proposals that specify materials, quantities, and methods
[ ] Verify contractor licenses through the Oregon Construction Contractors Board (CCB)
[ ] Check insurance certificates including general liability and workers compensation
[ ] Request references from similar commercial projects completed in the last 2 years
[ ] Ask about warranties for materials and workmanship

Evaluate Bids Properly

The lowest bid is not always the best value. Compare bids on these criteria:

| Evaluation Criteria | What to Look For | |--------------------|-----------------| | Material specifications | Asphalt mix type, aggregate base depth, compaction standards | | Scope completeness | Does the bid include everything? Mobilization, striping, cleanup? | | Timeline | Realistic schedule with weather contingency days | | Payment terms | Progress payments tied to milestones, not just start/finish | | Warranty | Minimum 1-year workmanship warranty, material warranty terms | | Insurance | Current certificates with adequate coverage limits |

For a more thorough evaluation framework, see our guide on evaluating paving contractor bids.

Check References

Contact at least two references for your selected contractor:

[ ] Was the project completed on time and within budget?
[ ] How was communication throughout the project?
[ ] Were any issues handled professionally?
[ ] How does the pavement look 1-2 years later?
[ ] Would you hire them again?

Phase 4: Pre-Construction Planning (Weeks 5-7)

Schedule the Work

Timing is critical for paving projects in Oregon:

[ ] Book your contractor early. The May-October season fills up fast.
[ ] Build in weather contingency days. Even summer months see occasional rain.
[ ] Coordinate with tenants. Notify all affected businesses at least 2-3 weeks in advance.
[ ] Plan phasing if the lot must remain partially open during construction.
[ ] Schedule utility locates. Call 811 at least 2 business days before any excavation.

Plan for Business Continuity

Your parking lot will be partially or fully unavailable during construction:

[ ] Identify alternative parking for customers and employees
[ ] Create a traffic management plan for phased construction
[ ] Notify customers through signage, email, and social media
[ ] Coordinate delivery schedules to avoid conflicts with construction
[ ] Arrange temporary signage directing customers to alternative access

Finalize the Contract

Before signing, confirm these items are in the contract:

[ ] Detailed scope of work with material specifications
[ ] Project timeline with start date, milestones, and completion date
[ ] Total price with payment schedule tied to milestones
[ ] Change order process for handling unexpected conditions
[ ] Warranty terms for materials and workmanship
[ ] Insurance requirements and certificates
[ ] Cleanup and site restoration responsibilities
[ ] Cancellation and dispute resolution terms

Phase 5: Construction Management (Project Duration)

Pre-Construction Meeting

Hold a meeting with your contractor before work begins:

[ ] Walk the site together and confirm the scope
[ ] Review the construction schedule day by day
[ ] Establish communication protocols (daily updates, point of contact)
[ ] Confirm equipment staging and material delivery locations
[ ] Review safety requirements and site access restrictions

During Construction

Stay engaged throughout the project:

[ ] Monitor daily progress against the schedule
[ ] Document everything with daily photos and notes
[ ] Address issues immediately rather than waiting for completion
[ ] Verify material quality by requesting delivery tickets for asphalt loads
[ ] Watch for compaction and make sure the contractor is testing density
[ ] Inspect base preparation before asphalt is placed (this is your last chance to catch problems)

Quality Checkpoints

Key moments to inspect the work:

After demolition/removal: Verify the subgrade condition before base installation
After base installation: Check base thickness and compaction before paving
During paving: Monitor asphalt temperature, lift thickness, and roller patterns
After paving: Check final grades, smoothness, and drainage flow
After striping: Verify ADA compliance, line accuracy, and marking clarity

Phase 6: Project Closeout

Final Inspection

Walk the completed lot with your contractor:

[ ] Verify all work matches the contract scope
[ ] Check drainage by observing water flow during rain or hosing
[ ] Inspect transitions between new and existing pavement
[ ] Confirm all striping is accurate and ADA-compliant
[ ] Note any punch list items for correction

Documentation

Collect and file these documents:

[ ] Final invoice and proof of payment
[ ] Warranty documentation
[ ] As-built drawings (if applicable)
[ ] Material delivery tickets and test reports
[ ] Permit closeout confirmation
[ ] Contractor contact information for warranty claims

Start Your Maintenance Program

Your new or resurfaced parking lot needs a maintenance program from day one. Develop a plan that includes sealcoating, crack sealing, and regular inspections. See our guide on creating a pavement maintenance plan for details.
