Operations Division General Permit Manual

Section 1 - Scope 1

INTRODUCTION

The Operations Divisions of Underground Utilities and Public Infrastructure (UU&PI) as well as Community Beautification & Waste Management Services (CBWMS) is responsible for routine maintenance and minor construction of public facilities. As related to environmental concerns, all aspects of maintenance and beautification activities routinely undertaken by the various units within the Operations Divisions shall be conducted in accordance with this manual. The City of Tallahassee UU&PI & CBWMS Departments through the Operations Divisions provides labor, material, and equipment necessary for the completion of repairs, maintenance, beautification and construction of facilities within City rights of way, public easements and drainage facilities. In completing such work, it's our intention to make every effort to be sensitive to the environment and provide adequate measures to protect natural resources. The Divisions will continue their commitment to protect the environment as part of all its operations. The Divisions will comply with all applicable regulations as set forth by the US Environmental Protection Agency, Northwest Florida Water Management District, Leon County Environmental Management Act, the City of Tallahassee Land Development Code (LDC) Chapter 5 ENVIRONMENTAL MANAGEMENT and any other authorized regulatory agency.

GENERAL PERMIT LIMITATIONS

The following activities are not authorized under the scope of this general permit and shall require a separate environmental management permit:

• Any newly proposed or relocated utilities or development activity in a “Conservation or

Preservation Area” as defined in Section 5. (Note - Routine maintenance activities for existing utilities may be allowed provided they do not interfere with the beneficial functioning of the conservation or preservation area. Prior to undertaking such maintenance activities, the unit supervisor shall contact Growth Management’s senior environmental inspector and environmental biologist for review and approval of proposed activities.)

• Damaging or removal of “protected trees” as defined in Section 2.

SECTION 1 – SCOPE TYPICAL ACTIVITIES

ROADWAY, SIDEWALK & DRAINAGE MAINTENANCE

The LDC Chapter 5 ENVIRONMENTAL MANAGEMENT Section 5-57 General Permit specifically allows for:

• The construction or reconstruction of stormwater conveyance systems not to exceed 1,000 feet in length or more than five structures.

• The maintenance, construction, or reconstruction of sidewalks, curbs, milling or resurfacing existing roadways, or other similar activities, as determined by the Growth Management director.

• Maintenance and/or construction activity that would not cause a net increase of 3,000 square feet or more of impervious area with the exception of sidewalks.

Section 1 - Scope 2

• Routine daily maintenance of existing parks and recreation facilities including minor landscape installations of 5,000 disturbed square feet or less, irrigation system installations within park boundaries and landscape areas within the public rights-of-way, 1,000 square feet or less of additional impervious surface area, or other routine maintenance activities necessary to restore such facilities to original construction conditions or to meet current code requirements.

• Routine daily maintenance of existing facilities or non-routine emergency maintenance requiring immediate response to protect public health, safety, and welfare.

• Routine roadway, shoulder, ditch, and stormwater facility maintenance, and rehabilitative activities necessary to restore such facilities to original construction conditions or to meet current code requirements.

In addition and to compliment the allowed work in Section 5-57, the following types of work shall be allowed under the general permit as specified and contained in the Operations General Permit Manual. The work completed by the Divisions on a regular basis includes, but is not limited to the following:

DRAINAGE CONVEYANCE FACILITY CONSTRUCTION AND PROJECTS

The FDOT design standard is between 150 to 300 feet between structures (Average of 200 LF). If five structures are repaired consistent with the LDC General Permit requirements 1,000 feet of pipe will be disturbed. Therefore, the Operations Divisions General Permit allows stormwater systems to be reconstructed up to 1,000 feet of pipe or five structures.

NEW FACILITY CONSTRUCTION AND PROJECTS

New facility construction includes installation of recreation items or equipment which did not previously exist, such as, new curb & gutter, new fencing, aesthetic amenities, pouring concrete areas less than 3,000 sq. ft., work order projects, and capital development projects. New projects would typically be described as new installation of features within the Right of Way, including all excavation required for roadway and drainage construction or other amenities to make the facility safer and easier to utilize and maintain.

REPLACEMENT CONSTRUCTION

Typically includes the replacement of any existing features such as resurfacing, fencing, existing structure repair, reconstruction of roadway base, reconstruction of drainage structures and sodding.

SPECIAL BEAUTIFICATION PROJECTS

Work performed on City of Tallahassee Right of Way, landscaped area, medians and easements. This includes the layout, preparation, planting, pruning, spraying, irrigation, etc. of shrubs or other decorative plant material in areas of 5,000 square feet or less.

Section 1 - Scope 3

TURF MAINTENANCE

Work performed on City of Tallahassee Right of Way and easements. This includes litter pickup, mowing and trimming, laying sod, fertilizing and top dressing.

LANDSCAPING

Landscaping, to modify or ornament the natural lay of the land by altering the plant cover, activities typically include new plantings of trees, shrubs, seasonal changing of annual plantings, renovation of existing ornamental beds, irrigation installation or repair, transplanting, laying sod or replacement of sod. Landscaping may include the necessary work required to prepare for a donation of plant materials from outside donors; example, bed preparation, roto-tilling; grading and drainage related work.

LANDSCAPE CONSTRUCTION

Construction of landscape features or hardscape, such as brick work, walks, patios, trails and other features such as steps, water, fountains; repair of existing landscape features;

work done in connection with an outside donation of a landscape feature, example: making a slab for a fountain to rest on or providing electric or water service to that landscape feature.

ORNAMENTAL PEST AND DISEASE CONTROL

Typically involves the use of insecticides, fungicides and herbicides to control insects, diseases and weeds on the grounds.

ASSISTANCE TO OTHER UNITS/DEPARTMENTS

Work performed after the routine beautification or landscaping for the benefit of other units or departments, such as, work performed at a special event, erecting temporary staging, bleachers and decorating items for special events, etc.

MAINTENANCE OF PERMITTED STORMWATER FACILITIES

Typically, this work involves inspecting the stormwater facilities at least annually and taking the necessary actions required to ensure the facility is functioning properly. Inspections will be performed with the intent of minimizing interference of the proper function of the facility resulting from sediment accumulation, weed and brush overgrowth and from structural failures within the stormwater facility.

Section 1 - Scope 4

INSPECTIONS

Each pond will be inspected at least annually. The inspection will include:

o A visual evaluation of structural components assessing that they are in working order and structurally sound. Structures to be inspected include inflow, outfall structures, spillways, retaining walls, concrete bottoms, sand bags or fabriform and steel grates or equivalent devices.

o If the pond has a sand filter, an evaluation of the filter system will be made. A measurement of the sand filter will be taken. The minimum cover over the sand filter is 12 inches from the top of the sand to the subsurface drain. A visual observation of the filter media will be made. If algae is present over two thirds of the filter bed area, maintenance is required to remove the algae.

Standing water above the filter pipe shall be measured. If it is greater than six inches, further investigation of the operation of the filter will be made. This will indicate whether or not the filter is draining in an appropriate time period.

o An evaluation of sediment buildup within the pond will be made. If the sediment buildup restricts the flow in the entrance pipe or ditch, UU&PI Drainage Operations Division will schedule the pond for dredging. Additionally, if the pond bottom has excessive sediment, the pond will be scheduled for dredging.

o An evaluation of the side slopes will be made. The inspector will specifically look for stability and erosion problems.

o The landscape and fencing will be inspected. Code required plant materials along the bank that are dead, dying or missing shall be scheduled for replacement. All fences and gates shall be inspected for security. Any breach of this barrier shall be repaired immediately.

MAINTENANCE ACTIVITY

The specific maintenance activity for each pond will be determined based on the routine schedule, customer calls and the results of field inspections or as indicated by a pond specific Operation and Maintenance plan.

Mowing of each pond will occur at a minimum of twice per year.

Sediments will be removed based on the results of periodic inspections conducted by UU&PI Operations staff.

Filters will be cleaned or replaced based on the results of the inspection of the filter.

Section 1 - Scope 5

MAINTENANCE RECORDS

The Operations Divisions will maintain records of all maintenance activity for stormwater facilities under the jurisdiction of UU&PI & CBWMS.

The Operations Divisions will make any and all facility maintenance records available to Growth Management staff for review and audit.

Section 2 - Tree Removal Relative to Canopy 9

TREE REMOVAL –Removal of a protected tree is not authorized by this general permit. Tree removal is defined as the actual removal of a tree; any unmitigated development impact the tree protection zone of a tree; any encroachment within the radius of the tree protection zone of a protected tree; any damage/removal of 30% or more of the crown of a protected tree; or any other action likely to damage a protected tree.

Exemptions – Tree removal under one of more of the following circumstances is authorized to the extent conditioned below. However, no trees shall be removed before coordinating with the Growth Management senior environmental inspector and the Community Beautification Operations Manager.

SAFETY HAZARD

Removal of any tree within the right of way which is in such a dangerous condition or poses such a hazard as to endanger pedestrians or other persons, buildings or other property, or vehicular traffic, or which threatens to cause disruption of public services and therefore require immediate removal.

DISEASED, PEST-INFESTED, OR INVASIVE TREES

Trees that are diseased or pest-infested may be removed to prevent the spread of such disease or infestation. Removal of noxious invasive trees: Camphor, Chinese Tallow, Mimosa, Tung Oil, Chinese Umbrella Tree, China Berry or any other trees listed in the Florida Exotic Pest Plant Council Invasive Plant List (Class I and II species).

EMERGENCY SITUATION

Removal of any tree during or following an emergency or an act of nature, when the Growth Management Director determines that permitting requirements will hamper private or public work to restore order to the city.

General Procedures for New Landscape Installation, Landscape Renovation and Transplanting by Non-Mechanical Means Within a Critical Protection Zone

1. No rototilling shall occur within a tree's Tree Protection Zone.

2. Do not sever roots 3/4 " in diameter or larger.

3. Install new plant material as high as possible to minimize existing root damage, while maintaining proper horticultural procedures.

4. Mulch, if applicable, fertilize and thoroughly water. Do not allow root ball of new material to dry out.

5. No fill over is allowed in the tree root zone.

NOTE: Any tree roots 3/4 inches in diameter or larger will be removed, after approval of the arborist, with handsaw to provide for a clean cut. DO NOT use machinery to make these cuts. Using machinery (example backhoe) will result in root cuts that will be ragged and can peel the outer layer of the root exposing the root to disease.

TREE PROTECTION BARRIERS

Section 2 – Tree Barriers 10

Barriers Required. During development, including installation of irrigation systems or any other underground installations, protective barriers shall be placed around each protected tree not permitted for removal to prevent the destruction or damaging of roots, stems or crowns of such trees. The barriers shall remain in place and intact until such time as approved landscape operations begin; however, barriers may be removed temporarily to accommodate construction needs, provided that the manner and purpose for such temporary removal will not harm the tree and is approved by the Growth Management senior environmental inspector (inspector). The following are minimum requirements for barrier types:

1. Protective posts shall be placed so as to protect the critical protection zone for each tree not permitted for removal.

2. Posts shall be of nominal two inches by four inches or larger wooden post, two inches outer diameter or larger pipe, or other post material of equivalent size; shall be strung with at least 1 one-inch by four-inch wooden stringer; and shall be clearly flagged.

3. Posts shall be implanted deep enough in the ground to be stable and to extend to a minimum height of four feet above ground. 4x4 pressure treated post shall be placed 8’- 0” to 10’-0” on center, connected by 2, 2x4 wooden rails. The rail shall be attached with screws or fluted nails.

4. Where the inspector determines that individual protective barriers are not needed in some areas for tree protection, such areas shall instead be clearly staked and flagged with readily visible markers.

5. Where development activity is permitted to occur within the critical protection zone of a protected tree, the inspector may require a protective girdling of at least the bottom four feet of the tree trunk base along with fencing or other approved techniques.

Section 2 – Tree Barriers 11

TREE PROTECTION BARRICADE TYPE I

4x4 pressure treated post shall be placed 8’-0” to 10’-0” on center, connected by 2, 2x4 wooden rails. The rail shall be attached with screws or fluted nails.

TREE TRUNK PROTECTION (N.T.S.)

Section 3 - Root Protection 13

SECTION 3 - ROOT PROTECTION

All routine maintenance relating to tree root protection, may be conducted by Operations Division personnel, at any time, without requiring an Environmental Permit provided such routine maintenance is carried out per the following:

MECHANICAL TREE SPADE OPERATION GUIDELINES

1. Impact in the "Critical Protection Zones" of existing trees shall be no more than 25% as defined by current City of Tallahassee Environmental Ordinances. If more than 25% of the Tree Protection Zone (TPZ) will be impacted, an approved mitigation plan shall be required.

2. Ensure maneuverability of tree spade with minimal impact in the TPZ and to other existing vegetation.

3. Prior to digging, locate all underground and overhead utilities.

4. The use of approved tree protection devices shall be incorporated for all projects where any impact on TPZ's may occur. Plywood "bridges" may be used for weight displacement of tree spade in all instances where any portion of TPZ is impacted.

Pine straw mulches, bark chips, cones, flagging may be used.

5. Trees or shrubs deemed to be unmovable by tree spade within a TPZ shall be hand dug. Trees or shrubs not to be transplanted shall be sawed down, allowing remaining roots and stump to decay.

6. The use of backhoes shall be permitted if machinery does not impact the TPZ, including access and set-up area. Set-up shall be outside of the TPZ where possible.

7. Ideally, trees that are to be moved with a spade should be hardened off prior to transplanting. This can be accomplished with severing the roots with the size spade intended for the transplant, or by means of hand digging and saw cutting roots along the outer edge of the anticipated spade diameter. The hardening off period should be no less than 8 weeks in duration.

MECHANICAL TREE SPADE OPERATION SEQUENCE

1. After satisfying all applicable aforementioned guidelines, select all transplants and intended locations.

2. Dig hole at location to receive first transplant and cleanly cut any exposed roots with a sharp lopper or "scissor-type" pruners. Transport soil to location of the scheduled last transplant.

3. After digging first transplant, repeat pruning procedures described in STEP #2.

4. Dig hole and scarify sides of hole to encourage root penetration. Transport transplant to the first hole, set, and water thoroughly. Fill with topsoil any air pockets exposed by watering and water again thoroughly.

5. Dig second soil plug and transport back to hole vacated by transplant #1. Fill hole, allowing plug to break up, thereby promoting aeration. Firm soil, then mulch, seed, or sod the entire disturbed area.

Section 3 – Root Protection 14

6. Repeat procedure for remaining transplants. Mark and barricade any hole left open overnight. Place soil rings around edge of all root balls to serve as water reservoirs and mulch with 3 inches of wood chips or pine straw. NOTE: As the level of on-site supervision increase, the amount of protection devices may decrease for short-term projects.

CHANGING GRADE

If a grade change is unavoidable, a retaining wall can be used to protect much of the root network. The retaining wall must be installed and backfilled and watered immediately so as to prevent the roots from drying out. It can also lend some pleasant diversity to the landscape.

ROOT PROTECTION IN CLOSE QUARTERS

Place timbers pointing in toward the tree trunk, like wheel spokes, and place plywood over the ties, fashioning a bridge across tree roots of protected trees. This will provide temporary protection for the root system.

Section 3 – Root Protection 15

IRRIGATION BORING

For the installation of irrigation systems in tree protection zones (TPZ) trenching across root systems shall not be used. Tunneling beneath root systems shall be utilized.

Section 3 – Root Protection 16

WRONG WAY RIGHT WAY

WRONG WAY RIGHT WAY

Nearly one half of the root system may be lost when trenches are made close to the trunk of the tree. Boring beneath the trunk of the tree results in minimal damage to the tree roots, minimum depth of bore should be 3 feet. You can reduce severing tree roots by trenching as far as possible from the tree, but no closer than the drip line (CPZ) of a tree.

Section 4 - Canopy Road Protection Zone 17

SECTION 4 - CANOPY ROAD TREE PROTECTION ZONE (CRPZ)

All lands within 100 feet of the center lines of all canopy roads, (Meridian Road from 7th Avenue to the state line, Old Bainbridge Road from Raa Avenue to Capital Circle, Miccosukee Road from Capital Circle to Moccasin Gap Road, Centerville Road from 7th Avenue to SR-59, and Old St. Augustine Road from East Lafayette Street to W.W. Kelly Road) are considered Canopy Road Tree Protection Zones. All trees within this zone, except for hazardous trees and non-native invasive species, are protected and may not be removed. (Underbrushing within the CRPZ will be permitted in accordance with the approved Vegetation Management Plan on file with the Growth Management Department.) A Tree Risk Assessment shall be performed by personnel qualified under the ISA Tree Risk Qualification, using the ANSI A300 Part 9: Tree Risk Assessment Best Management Practices. Those trees determined to have an Extreme or High Consequence of Failure may be removed upon coordination with the Growth Management senior environmental inspector.

SECTION 5 - CONSERVATION AND PRESERVATION AREAS

If any of the following natural features are in the proposed work, a Natural Features Inventory shall be required. A subsequent Environmental Impact Analysis and Environmental Management Permit shall be required for any project that significantly impacts a preservation or conservation area.

Preservation Areas Conservation Areas Water Bodies Altered Floodplains Watercourses Altered Floodways Undisturbed Floodplains Altered Wetlands Wetlands Closed Drainage Basins Native Forests High Quality Successional Forests Severe Grades (greater than 20%) Significant Grades (10-20 %) Habitats of Endangered and Threatened Species & Species of Special Concern

Altered Water Courses & Improved Elements of the Primary Drainage System

Areas of Environmental Significance Active Karst Features Special Development Zones Canopy Roads

SECTION 6 - PRUNING STANDARDS

All pruning operations shall comply with ANSI Standard A300 and all general tree operations shall comply with ANSI Standard Z133.1. A copy of the current versions of these standards is kept in the office of the Community Beautification Operations Manager and is included in this permit by reference.

Section 7 - Erosion Control 18

SECTION 7 - EROSION CONTROL

Trenching and excavation are routine maintenance activities which have the potential to result in erosion, and sediment leaving the work site. As such, the unit supervisor shall designate a stormwater control officer for each work activity that involves earth work disturbance. The stormwater control officer shall have the responsibility and authority within the project administration for managing the site work, preventing erosion and constructing whatever perimeter protection is necessary to prevent the direct flow or tracking of sediments onto adjacent property, conservation areas, public streets, or drainage systems during all phases of construction. Failure to install and maintain erosion and sediment control measures may result in an immediate STOP WORK ORDER. Any sediment, gravel or mud that is spilled, dropped, washed, or tracked from vehicles onto adjacent property, roadways or into off-site storm drainage systems shall be recovered immediately and disposed of properly.

City crews shall keep sediment filtering devices and silt barriers on site. Erosion controls shall be in place as shown in the following illustrations prior to beginning construction and during inclement weather and/or on projects of more than 1-day duration.

TRENCHING - General trenching operations for installation of electric, water, phone, cable, irrigation and drain lines.

1. If an impact within the tree protection zone of a protected tree is unavoidable, a separate Environmental Management Permit may be required prior to beginning earthwork activities. Contact the Growth Management senior environmental inspector for further instructions.

2. Run all main lines outside of critical protection zone where possible.

3. Run laterals in radial formation to minimize cross-cutting of existing roots.

4. Prune with sharp loppers or scissor-type" pruners any cut existing roots. Immediately apply a broad-spectrum fungicide.

5. If leaving open trenches overnight is unavoidable, barricade and mark trench to prevent pedestrian/bike injury.

6. Backfill, tightly compact, and mulch, seed or sod disturbed area.

7. Protect all disturbed areas with sedimentation barriers for projects extending over 8 hours.

EXCAVATION - Non-routine large-scale excavations and grade changes will require environmental permits through applicable city or county agencies. Routine excavation for repair or construction of walks, paths and trails, retaining walls, foundation construction, and drives shall be allowed under the general permit.

A. Dirt stored on site overnight shall be covered with a tarp or contained with siltation devices. Disturbed vegetation shall be back filled and compacted. Upon completion of work, these disturbed areas shall be seeded and mulched or sodded if determined necessary.

Section 7 – Erosion Control 19

B. Methods - Methods of control shall be suitable for the work site size, vegetative cover, soil type, slope design features, proposed sequence of work and the type of activities involved.

1. Limiting the amount of clearing necessary.

2. Stage clearing activities to minimize the length of time any area is left un-stabilized.

3. Sediment filtering devices

4. Silt fences

5. Staked silt barriers

6. Storm drain inlet protections

7. Temporary diversion dikes

8. Temporary sediment traps

9. Sodding

10. Erosion control and seeding mats

11. Other suitable methods of environmental management

SEDIMENT BARRIERS

The placement of gravel construction entrances and sediment filtering devices for the purpose of perimeter sediment control shall conform to the best management practices (BMPs) established by the Florida Department of Environmental Protection (FDEP). Refer to Chapter 6 of the Florida Development manual.

Section 7 – Erosion Control 20

GRAVEL CONSTRUCTION ENTERANCE/EXIT

SILTATION FENCING

1. A temporary silt fence sediment filter barrier consisting of a filter fabric stretched across and attached to supporting posts shall be utilized to intercept and detain small amounts of sediment from disturbed areas during construction operations in order to decrease the velocity of sheet flows, and to prevent sediment from leaving the site.

2. Do not trench-in silt fence in tree root zones. Fit on top of existing ground.

3. Silt fences shall be erected below disturbed areas where erosion would occur in the form of sheet and rill erosion.

4. Sediment deposits should be removed after each storm event. They must be removed when deposits reach approximately one-half the height of the barrier.

5. Any sediment deposits remaining in place after the silt fence or filter barrier is no longer required, shall be dressed to conform with the existing grade, prepared and seeded.

Section 7 – Erosion Control 21

INSTALLATION CONTINUOUS ROLL FILTER FABRIC

Continuous Roll Filter Fabric is a commercially produced siltation fence and may be purchased locally. Continuous roll filter fabric, including hardwood stakes may be installed only for controlling sheet flow drainage in an area less than 1/4 acre, using a maximum of 100 linear foot of siltation fence. To determine a quarter of an acre, use the following table:

¼ Acre Size Conversion Table 1 acre equals 43,560 sq ft yields quarter acre 10.890 square feet square feet 30' X 1452' 15' x726' 60' X 726' 30' X 363' 90' X 484' 45~ X 242' 132' X 330' 66' X 165' 180' X 242' 90' X 121' The placement of filter fabric and hay bales for the purpose of erosion and sediment control require a trench to be dug for each of the following details. It should be noted that the trench shall not be dug within the Tree Protection Zone (TPZ) of any protected or desirable tree where installation is required.

Section 7 - Erosion Control 22

STOCKPILED EARTHEN MATERIAL AT JOB SITE

All stockpiled earthen materials, such as, sand/clay, trail material, soil material, dirt, etc., provided on location for an intended construction project shall have a tarpaulin held in place over the material to prevent erosive flow of the material. Appropriate sediment and erosion control systems, such as temporary siltation fence, shall be erected surrounding the stockpile for the duration of the project to prevent material from eroding into the conveyance system of the site.

BERM, SWALE, AND DIVERSON DIKE MAINTENANCE

The Operations Divisions staff maintains berms, swales, and diversion dikes, throughout the city. They exist and will be managed under the General Permit. When reconstruction of existing water diversion devices take place, the following procedures shall be applied:

1. Coordinate reconstruction with stabilization.

2. Erosion shall be minimized and sediment retained during the reconstruction.

3. Proper erosion control devices shall be in place as illustrated, prior to beginning construction and during inclement weather and/or on projects of more than one-day duration.

4. After construction, the soil shall be stabilized with sod, seeded, or mulched, whichever is appropriate.

5. Small swales in conjunction with landscaping at our facilities may be constructed under the General Permit following the above outline.

DIVERSION DIKE MAINTENANCE

A temporary diversion dike ridge of compacted soil located at the top or base of a sloping disturbed area shall be used to divert storm runoff from higher drainage areas away from unprotected slopes to a stabilized outlet wherever storm water runoff must be temporarily diverted to protect disturbed slopes or retain sediments on site during Construction. A temporary diversion dike Is Intended to divert overland sheet flow to a stabilized outlet or a sediment trapping facility during establishment of permanent stabilization on sloping, disturbed areas. When used at the top of a slope, the structure protects exposed slopes by keeping upland runoff away. When used at the base of a slope, the structure protects adjacent and downstream areas by diverting sediment-laden runoff to a sediment trapping facility. The slope behind the dike is also an important consideration. The dike must have a

Section 7 – Erosion Control 23 positive grade to assure drainage, but if the slope is too great, precautions must be taken to prevent erosion due to high velocity flow behind the dike. Providing vegetation for stabilization may extend the useful life of the dike.

FLOATING TURBIDITY BARRIERS:

Floating turbidity curtains/barriers may be used in water courses where intrusion into the watercourse by the construction activity is permitted and sediment movement is unavoidable.

Section 7 – Erosion Control 25

RESTORATION OF WORKSITES

Any grass, shrubbery, or planting removal to accomplish work details, shall be replaced. All areas disturbed during the work shall be restored to a condition equal to or better than that existing prior to beginning work. It is recognized that some special situations may require efforts beyond grassing and mulching. Included in restoration, is the protection of slopes subject to rapid erosion. Except where soil-cement/rip-rap is installed, this protection shall be by grassing and mulching. A satisfactory stand of grass shall be obtained by sprigging, sodding, or seeding over entire work site.

WORKSITE CLEAN-UP

Cleanup is an essential part of the work. As the work progresses the cleanup shall be done as promptly as practicable and shall not be left until the end of construction period.

TRAINING CLASSES

The Operations Divisions will offer training classes for its supervisory personnel to familiarize the employees with the General Permit and a copy will be provided to each Crew Leader/Foreman/Supervisor involved in work requiring the utilization of the General Permit.

STOCKPILED EARTHEN MATERIAL AT MUNICIPAL COMPLEX

The Operations Divisions maintains active stockpiles of earthen material at the Municipal Complex and satellite facilities. Erosion of these materials is controlled on site by using sediment control devices including silt fence, sediment filtering devices that are inspected daily and maintained or repaired as needed.

STOCKPILED RECYCLED ASPHALT MATERIAL AT MUNICIPAL COMPLEX

The Operations Divisions maintains active stockpiles of recycled asphalt material at the Municipal Complex and satellite facilities. Erosion of these materials is controlled on site by using sediment control devices including silt fence and sediment filtering devices that are inspected daily and maintained or repaired as needed.

DEFINITIONS

BRANCH – Stem arising from a larger stem. A subordinate stem.

BRANCH BARK RIDGE - Raised strip of bark at the top of a branch union, where the growth and expansion of the trunk or parent stem and adjoining branch push the bark into a ridge.

BARK TRACING - Cutting away torn or injured bark to leave a cleanly cut edge.

CALLUS - Undifferentiated tissue formed by the cambium, usually as the result of wounding.

CANOPY - Collective branches and foliage of a tree or group of trees’ crowns. Aggregate or collective tree crowns.

CAMBIUM - Thin layer(s) of meristematic cells that give rise (outward) to the phloem and (inward) to the xylem, increasing stem and root diameter.

CLEAN CUTS - Cuts made using a sharp tool, with no nicks or tears on the branch collar or the trunk.

CLEARANCE- Amount of open space between a tree or tree part and another object, the ground, or pedestrian or vehicle traffic on the ground. Often used in reference to the distance between trees and utility lines.

CLOSURE - Refers to woundwood growth covering of a cut or other tree wound.

CROWN - Upper part of the tree, measured from the lowest branch, including all the branches and foliage.

CROWN RAISING - The selective removal of lower limbs from a tree crown to provide clearance.

CUT - The exposed wood area that remains after the branch has been removed.

CROWN REDUCTION - Method of reducing the height and/or the spread of a tree crown by making appropriate pruning cuts. It is distinctly different from "topping” (see definition) in that an effort is made to keep the symmetry of the tree on the sides as well as the top.

CROWN THINNING- The selective removal of live branches to reduce crown density.

DECAY - The degradation of plant tissue, including wood, by pathogens such as fungus organisms. Wood decay can reduce the structural integrity of a tree or its individual limbs.

DORMANCY - Period of naturally reduced physiological activity in the organs of a plant with the potential for reactivation of growth.

GIRDLING ROOTS -– Root that encircles all or parts of the trunk of a tree or other roots and constricts the vascular tissue and inhibits secondary growth and the movement of water and photsynthates.

LATERAL -– A secondary or subordinate branch or root.

LEADER -– Primary terminal shoot or trunk of a tree. Large usually upright stem. A stem that dominates a portion of the crown by suppressing lateral branches.

LIMB - Large, primary branch of a tree.

PARENT BRANCH - Larger branch or stem from which a smaller, lateral branch arises.

PHOTOSYNTHESIS - The process by which green plants form glucose from water and carbon dioxide, utilizing sunlight for energy.

POLLARDING - Specialty pruning technique in which a tree with a large-maturing form is kept relatively short, through frequent removal of sprouts arising above the pruning cuts.

PRUNING - The removal of plant parts, dead or alive, using approved practices, to achieve a specified objective.

REDUCTION PRUNING- The specific cutting back of a branch or leader to a lateral branch at least one-third the diameter of the cut being made.

SAP FLOW - The course assumed by sap in its movement through the vascular system of a tree.

SAPWOOD - A wood layer of variable thickness found immediately inside the cambium, which is active in the longitudinal transport of water and minerals. Also known as xylem.

SUCKER - Shoot arising from the roots or below the root graft.

SUNBURN - Injury to bark and cambium caused by a combination of excessive light and heat and insufficient soil moisture.

TOPIARY - Trees sheared or pruned carefully in a formal shape.

TOPPING -– Inappropriate pruning technique to reduce tree size. Cutting back a tree to a predetermined crown limit, often at internodes.

TREE REMOVAL- The actual removal of a tree; any unmitigated development impact to the critical protection zone of a protected tree; any damage to 30% or more of the crown of a protected tree within the vertical projection of its critical protection zone; or any other action or activity likely to damage a protected tree.

UTILITY LINE CLEARANCE PRUNING - Pruning for the safe operation and maintenance of uninterrupted electric service.

UNDERCUT - Cut on the underside of a branch or stem that is being removed to prevent unwanted tearing as part being removed falls. Typically this distance is 12-15 inches away from the final cut outside the branch bark ridge.

WATER SPROUT -– Upright, epicormic shoot arising from the trunk or branches of a plant above the root graft or soil line.

WOUND - The opening that is created any time the tree's protective bark covering is penetrated, cut, or removed injuring or destroying living tissue. Pruning a live branch creates a wound, even when the cut is properly made.
