About this file
This is a Standard Specifications document for Site Clearing (Section 02230) issued by the Washington Suburban Sanitary Commission (WSSC Water) for water and wastewater asset repairs and replacements in Prince George's and Montgomery Counties, Maryland. The specifications establish requirements for clearing and grubbing operations within contract limits, including removal of trees, brush, shrubs, and debris from right-of-way areas and other designated locations. All tree care work must be performed by a Maryland Licensed Tree Care Expert under the supervision of a Maryland Certified Roadside Tree Care Expert. The document provides detailed procedures for handling trees and shrubs in private property, dedicated public space, and park property owned by various agencies including the National Capital Planning Commission and the National Park Service. Specific requirements address tree protection, root pruning near existing trees to be saved, removal of trees greater than six inches in diameter at breast height in eight to ten-foot sections, and transplanting of designated species such as Dogwoods as directed by park authorities.
The specifications establish that site clearing costs are not separately measured or paid but are considered incidental to the overall contract. Detailed procedures govern topsoil stripping and stockpiling, with materials placed in well-drained locations approved by the Engineer. Grubbing requirements vary by fill depth: areas receiving less than three feet of fill or designated for structures require removal of stumps and root mats to a minimum of one foot below subgrade, while areas receiving more than three feet of fill require only cutting vegetation close to existing ground. The document mandates compliance with erosion, sediment control, and stormwater management measures, permits requirements set forth by the Maryland Department of Natural Resources Forest Service, and applicable local ordinances. Tree and shrub damage must be repaired within twenty-four hours by a state-licensed tree expert, and all removed materials must be disposed of at authorized sites in accordance with Section 01770 specifications.
