Top Parking Lot Resurfacing Contractors in St Paul, Minnesota Ranked

Parking lot resurfacing is a crucial maintenance procedure that restores a worn asphalt surface, extending its life and improving safety and appearance. In St. Paul, this process, often called a mill and overlay, is essential for property owners to maintain compliance with local codes and protect their investment. This guide explains the local process, costs, and regulations to help you understand your options and connect with qualified local paving professionals for your project.

What is Parking Lot Resurfacing?

Parking lot resurfacing, also known as an asphalt overlay, is a process designed to renew a pavement surface that is aged and cracked but has a structurally sound base. In St. Paul, the standard method is a mill and overlay, where the top 1.5 to 2 inches of damaged asphalt is mechanically ground off (milled) and replaced with a fresh layer of hot mix asphalt ¹. This approach is cost-effective compared to a full reconstruction and can extend the life of your lot by 8 to 15 years. It's the ideal solution when the foundation is still solid but the surface shows signs of weathering, alligator cracking, or minor deterioration.

The Resurfacing Process: A Step-by-Step Guide

A successful overlay project follows a meticulous sequence. Understanding these steps can help you plan effectively and communicate with contractors.

1. Site Assessment & Planning: The first step is a professional evaluation to confirm the lot's base is intact. Resurfacing is only effective on a solid foundation; if the sub-base has failed, a full replacement is needed. This phase also involves planning for drainage and reviewing St. Paul's specific zoning and landscaping requirements.
2. Permitting: Most commercial resurfacing projects in St. Paul require permits from the Department of Safety and Inspections (DSI). A site plan review may be necessary to ensure the project meets zoning, drainage, and traffic standards ². Commercial operations also need a valid Parking Lot License³.
3. Milling: Using heavy machinery, contractors grind off the designated top layer of old asphalt. This typically takes 1-2 days and creates a clean, level surface for the new layer while managing material removal.
4. Repair & Preparation: Before new asphalt is laid, the milled surface is cleaned. Any remaining potholes or isolated base failures are repaired to ensure a uniform, stable foundation for the overlay.
5. Tack Coat Application: A thin layer of liquid asphalt, called a tack coat, is applied. This acts as a bonding agent, ensuring the new overlay properly adheres to the old pavement below.
6. Paving/Overlay: Hot mix asphalt (heated to approximately 350°F) is laid using a paving machine to a compacted depth of 1.5" to 2". Proper compaction is critical for durability.
7. Striping & Landscaping: Once the new surface has cooled, parking stall striping, handicap symbols, and directional arrows are reapplied. For lots with over 20 spaces, St. Paul requires interior landscaping, which must be installed or refreshed as part of the project completion.

St. Paul Regulations and Standards

Compliance with local codes is non-negotiable. St. Paul has clear standards for both residential and commercial parking areas.

• Paving Requirement: All parking lots for commercial uses and residential buildings with 1-6 units must be paved with asphalt, concrete, or authorized pavers; gravel is not permitted.
• Residential Standards: For 1-6 unit housing, parking is usually restricted to the rear yard and cannot cover more than 10-15% of the lot area. It must be set back at least 4 feet from side and rear property lines ^{4 5}.
• Commercial Standards: Lots must include concrete curb stops. If a lot contains more than 20 spaces, interior landscaping is mandatory for screening and environmental management ⁶.
• Drainage: All paving must be designed so water drains away from buildings and adjacent properties to prevent pooling and damage ⁷.

Cost of Resurfacing in St. Paul

Costs for asphalt overlay in the Minneapolis/St. Paul area are typically calculated per square foot. For standard commercial projects, you can expect a general range of $1.50 to $2.00 per square foot^{8 9}. However, the final price depends on several factors, including the depth of the overlay, the amount of preparatory repair work needed, and site accessibility.

• Small Lot Example: Resurfacing a 5,000 sq ft lot (approx. 15-20 spaces) may cost between $7,500 and $15,000 ¹⁰.
• Large Lot Example: A 30,000 sq ft lot (approx. 100 spaces) could range from $45,000 to $90,000 or more^{11 12}.

Always obtain detailed, written estimates from local contractors that break down milling, material, labor, repair, and permitting costs.

Ideal Timing and Conditions for Paving

Asphalt paving is highly dependent on weather and ground conditions. In Minnesota, the paving season is generally from May through October¹³.

• Temperature: Hot mix asphalt requires a warm base (typically above 50°F) to be placed and compacted properly. If the ground or air is too cold, the asphalt cools too quickly, leading to poor compaction and premature failure ¹⁴.
• Ground Conditions: Projects should be scheduled when the soil is dry. Paving over saturated ground can lead to improper compaction of the sub-base, causing dips and cracks later.
• Planning: Schedule your assessment and permitting process well in advance of your desired paving date to secure a spot on a contractor's schedule during the optimal weather window.

Key Considerations Before You Begin

• Timing is Everything: Don't wait until the base fails. If cracks are extensive and allow water to seep into the sub-base, resurfacing is merely a temporary fix. A professional assessment will determine if an overlay or a full replacement is needed ¹⁵.
• Access and Communication: For commercial or multi-tenant properties, plan for full lot closure during milling and paving. Provide tenants and users with at least 24 hours advance notice to move vehicles and avoid towing.
• Material Specifications: All work must comply with St. Paul's standard specifications for materials. Ensure your contractor uses approved hot mix asphalt and follows proper compaction standards ¹⁶.
