Parking Lot

PARKING LOT — TEAMMATE INSTRUCTIONS WHAT THIS IS Herbicide application to weed growth in and around asphalt or concrete parking lots — cracks, expansion joints, perimeter edges, curb lines, and any adjacent unpaved margins. Typically a commercial or multi-unit residential service location. UNIQUE CONSIDERATIONS - Parking lots have high vehicle and foot traffic — application timing relative to traffic flow is important for both safety and product effectiveness. - Asphalt and concrete surfaces drain to storm drains — product selection and application rate matter for environmental compliance. - Perimeter edges often transition directly to lawn, beds, or natural areas — drift and runoff control at these edges is critical. - Some herbicide formulations and carriers can discolor or damage painted striping or specialty coatings. - Commercial properties may require advance notice to clients or tenants before treatment. PRODUCT RESTRICTIONS - Non-selective herbicides are standard for parking lot crack and perimeter treatment. - Soil sterilant products are appropriate for fully paved lots with no adjacent landscape — do not use where edges transition to lawn, beds, or trees within root zone distance. - Do not use oil-based carriers on asphalt — they can soften asphalt surfaces and create slip hazards. - Avoid high-volume application that creates runoff toward storm drains. ENVIRONMENTAL & LEGAL FLAGS - Storm drain inlets in parking lots connect directly to municipal stormwater — regulated under the Clean Water Act. Minimize runoff by using targeted, low-volume applications. - Do not spray directly into or immediately adjacent to storm drain openings. - If the lot borders a natural area, riparian zone, or retention pond — apply buffer rules from the Retention Pond term to that edge. - Commercial properties may have environmental compliance requirements beyond standard label compliance — ask your supervisor if uncertain. FIELD RULES — DO - Identify storm drain locations before starting. - Confirm traffic flow — apply during low-traffic periods where possible. - Notify the account contact before treatment if required by the account. - Use targeted application at cracks and perimeter edges — minimize surface runoff. - Keep product away from storm drain openings. FIELD RULES — DO NOT - Do not use oil-based carriers on asphalt surfaces. - Do not apply soil sterilants where the lot edges transition to landscape or trees. - Do not spray in conditions that will create runoff toward storm drains. RECORD-KEEPING NOTES Document property name, lot type (asphalt/concrete), approximate area treated, product used, storm drain proximity, and traffic conditions at time of application. Note any edges treated differently due to adjacent landscape.
