About this file
This is a specification document for landscape protection requirements issued by Horsham Township, Pennsylvania, as part of the 234 McKean Road Demolition project (26-00182). The specification establishes standards and procedures for protecting existing plant materials during construction activities, including the installation of temporary protective fencing around trees and vegetation designated to remain on the site. The contractor is responsible for conducting a site assessment to determine appropriate protection measures based on plant type and location, with the engineer arranging a pre-construction site inspection to review specific landscape protection concerns. Key requirements include erection of temporary fencing at a minimum distance of 15 feet from tree trunks or to the dripline, whichever is greater, prior to any earthmoving or construction activities. Temporary fencing specifications call for standard picket snow fence at 4 feet high or approved alternatives such as orange open mesh construction fencing, supported by high carbon channel bar steel posts of 7 feet in length with rivet-type fence holding lugs. The fencing must remain in place throughout the construction period and be periodically inspected and maintained to ensure continued integrity.
The specification establishes strict protocols for site management within protection areas, prohibiting toxic materials storage within 100 feet, prohibition of building, material storage, vehicle and equipment parking, and proper handling of exposed tree roots within four hours of severance through trimming and temporary coverage with moist biodegradable materials. Tree stumps within 10 feet of protection areas must be removed using stump grinders to minimize root system damage, and sediment retention or detention basins cannot be located within or discharge into protection areas. The project references Pennsylvania Department of Transportation Publication 408 Specifications as the applicable quality assurance standard and relates to concurrent work specified in sections covering soil erosion and sediment control, clearing and grubbing, and excavation, backfill and compaction. A mandatory pre-bid meeting is scheduled for Thursday, April 2, 2026, at 1100 Limekiln Pike, Ambler, PA 19002, with the broader project involving residential demolition, well capping, sanitary line abandonment, stream crossing restoration, and site grading and stabilization.

SECTION 01 56 39
PART 1 - GENERAL
1.01 SECTION DESCRIPTION
A. The Work of this Section Includes:
1. Provisions for landscape protection including the location and erection of protective fencing as may be appropriate for specific plant materials so as to insure their survival during and after completion of construction.
1.02 RELATED SECTIONS
A. Related Work Specified Elsewhere:
1. Section 01 57 13: Soil Erosion and Sediment Control
2. Section 31 11 00: Clearing and Grubbing
3. Section 31 23 33: Excavation, Backfill and Compaction
1.03 QUALITY ASSURANCE
A. Reference Standards
1. Pennsylvania Dept. of Transportation Publication 408 Specifications.
1.04 JOB CONDITIONS
A. Contractor is responsible for determining through site inspection and assessment of construction requirements what protection standards are necessary and practical based on plant type and location.
B. Engineer will arrange for a site inspection with Contractor prior to initiation of construction to review specific landscape protection concerns.
PART 2 - PRODUCTS
2.01 FABRICATED PRODUCTS
A. Temporary Fencing:
1. Undamaged, standard picket snow fence, 4' high, formed of wooden slats, tightly woven with wire cable; orange, open mesh construction fencing; or other acceptable, highly visible, weather resistant, easily maintained fencing that provides a substantial barrier.
2. High carbon channel bar steel posts, 7 feet in length. Designed to drive satisfactorily into the ground and with at least ten fence holding lugs of the rivet type. Alternate post types may be approved by Engineer.
PART 3 - EXECUTION
01 56 39-2
3.01 PREPARATION
A. Prior to initiating construction, Contractor shall assess the site area and determine the protection standards required in addition to any specifically noted on the Drawings. Unusual circumstances or exceptions to the standards specified shall be resolved by agreement with Engineer.
3.02 GENERAL REQUIREMENTS
A. Grade changes and excavation shall not encroach upon a protection area.
B. No toxic materials shall be stored within 100 feet of a protection area including petroleum based and/or derived products.
C. The area within a protection area shall not be built upon, nor shall any materials be stored there either temporarily or permanently. Vehicles and equipment shall not be parked in a protection area.
D. When tree stumps are located within ten feet of a protection area the stumps shall be removed by means of a stump grinder to minimize the effect on surrounding root systems.
E. Tree roots which must be severed shall be cut by a backhoe or similar equipment aligned radially to the tree to reduce the lateral movement of the roots during excavation, which could damage the intertwined roots of adjacent trees. Within four (4) hours of any severance of roots, all tree roots that have been exposed and/or damaged shall be trimmed cleanly and covered temporarily with moist peat moss, moist burlap or other moist biodegradable material to keep them from drying out until permanent cover can be installed.
F. Sediment, retention and detention basins shall not be located within the protection area or discharge into the protection area.
3.03 ERECTION OF TEMPORARY FENCING
A. Prior to start of construction or earthmoving, a snow fence or approved alternate shall be placed around plant material specified to remain at a distance of 15' from the trunk of the plant material or the distance from the trunk to the dripline whichever is greater. For a group of trees or woodlands, the fence location shall be determined by the aggregate distance or driplines for the individual plant. Exceptions to this requirement must be approved by Engineer.
B. Temporary fencing shall be periodically inspected and repairs accomplished to insure continued integrity during the construction period.
C. Temporary fencing shall remain in place until final restoration of the site is to occur.
