About this file
This is a Standard Specifications document for Section 02230 Site Clearing issued by the Washington Suburban Sanitary Commission (WSSC) in Maryland for 2026 projects. The document establishes requirements for clearing and grubbing within contract limits of rights of way and other designated areas, including removal of trees, brush, shrubs, timber, vegetation, rubbish, debris, fences, and incidental structures. All tree care work must be performed by a Maryland Licensed Tree Care Expert under supervision of a Maryland Certified Roadside Tree Care Expert. The specifications detail specific requirements for tree removal in three contexts: private property within rights of way, dedicated public space subject to Maryland Department of Natural Resources Forest Service standards, and park property managed by MNCP&PC, NPS, and MPS. For trees greater than 6 inches diameter at breast height, sections must be removed in 8 to 10 foot increments to avoid damage to retained trees. The document mandates protection of trees designated to remain, including root pruning protocols, protective barriers, and restrictions on material storage and equipment operation near tree drip lines.
The specifications establish grubbing requirements varying by fill depth, requiring removal of stumps and roots to a minimum of 1 foot below subgrade for areas receiving less than 3 feet of fill or areas designated for excavation or construction. For areas receiving more than 3 feet of fill, trees and shrubs need only be cut close to ground level without grubbing. The document includes provisions for topsoil stripping and stockpiling in well-drained locations with engineer approval, burning restrictions requiring written county agency permission, and damage repair requirements to be completed within 24 hours by a Maryland-licensed tree expert. Importantly, site clearing costs are not separately measured for payment but are considered incidental to the overall contract, meaning these costs are embedded within the broader project pricing rather than billed as a distinct line item.
