About this file
This is a Technical Specification document for Landscape Protection (Section 01 56 39) prepared for Montgomery Township in Pennsylvania, specifically for the Whistlestop Park project. The specification outlines comprehensive requirements for protecting existing landscape features during construction activities, including the installation of temporary protective fencing around designated plant materials at a minimum distance of 15 feet from tree trunks or to the drip line, whichever is greater. The work encompasses site assessment prior to construction initiation, erection and maintenance of temporary fencing constructed from standard picket snow fence (4 feet high) or approved alternatives with high carbon steel posts, and removal of tree stumps within 10 feet of protection areas using stump grinders to minimize root system damage. The contractor is responsible for determining protection standards necessary based on plant type and location, with any unusual circumstances requiring Engineer approval. Temporary fencing must remain in place until final site restoration occurs, and all work must comply with Pennsylvania Department of Transportation Publication 408 Specifications and National Arborist Association Standards for pruning practices.
Additional requirements include prohibitions on grade changes, excavation, toxic material storage within 100 feet of protection areas, vehicle or equipment parking, and material storage within protection zones. When tree roots must be severed, they must be cut radially to minimize lateral movement and trimmed cleanly within four hours, then covered with moist biodegradable material. All trees experiencing disturbance or root or branch damage require fertilization using a 3-1-1 nitrogen-phosphorus-potassium ratio at a rate of 1 pound nitrogen per 1,000 square feet, applied in early fall (September-October) or mid-spring (April-May), with fall applications preferred. The specification references related work in soil erosion control and finish grading sections, establishing landscape protection as an integral component of the overall construction project execution.

LANDSCAPE PROTECTION
01 56 39-1
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 32 92 00: Finish Grading, Seeding and Sodding
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.
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
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
01 56 39-2 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.
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 drip line 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.
3.04 PRUNING
A. All final cuts shall be made sufficiently close to the trunk or parent limb but without cutting into the branch collar or leaving a protruding stub, according to National Arborist Association Standards.
All necessary pruning cuts must be made to prevent bark from being torn from the tree and to facilitate rapid healing. Flush cuts are unacceptable.
3.05 FERTILIZATION
A. All trees which have experienced any disturbance or have had damage to the roots or branches shall be fertilized.
B. Trees shall be fertilized in early fall (September- October) or mid-spring (April-May). Fall applications are preferred.
C. Fertilizer grade shall have approximately 3 parts nitrogen to 1 part phosphorus and potassium (3-1-1 ratio).
D. Fertilizer shall be broadcast over the soil surface in an area twice the size of the protection zone at a rate of 1 pound nitrogen per 1000 square feet. A minimum of 1000 square feet per tree shall receive fertilization.
