1.8 PROTECTION OF LAWNS AND LANDSCAPING

B. Protect trees and tree roots of existing trees that are to remain.

1. To protect existing trees and roots, a Tree Protection Zone (TPZ) must be established.

a. The method of establishing a TPZ is to calculate a circular area above and below ground with a radius equivalent to the greater of 10 feet or 1.5 feet for every inch in trunk diameter measured 4.5 feet above the ground (for example, the TPZ of a tree twelve inches in diameter has an eighteen-foot radius). The area within the radius is the TPZ.

2. Tree fencing shall be made of wood or wire and erected before demolition, grading or construction begins and remain in place until final inspection of the project.

3. No excavation, trenching, grading, root pruning, dumping, or storage of material, topsoil, vehicles, and equipment, or any other activity, shall be permitted within the

TPZ.

4. The TPZ shall remain free of chemically injurious materials and liquids such as paints, thinners, cleaning solutions, petroleum products, and concrete or dry wall excess, construction debris, or run-off.

5. If an underground line must go near a tree, tunneling or augering must begin and end outside of the TPZ and be a minimum of 24" deep.

6. No soil disturbance is permitted within the TPZ. Trees to be retained shall be irrigated.

C. Any damage to existing trees will be evaluated by the ENGINEER or an appointed representative. Dollar value of damage will be determined using the most current edition of Guide for Plant Appraisal. Remediation for value lost and appropriate compensation will be determined by the ENGINEER, City Forester, or an appointed representative.

A. Best Management Practices (BMPs) - Schedules of activities, prohibitions of practice, maintenance procedures, and other management practices to prevent or reduce the pollution of Waters of the State. BMPs also include treatment requirements, operating procedures, and practices to control site runoff, spillage or leaks, waste disposal, or drainage from material storage.

B. Erosion - The wearing away of the land surface by water, wind, ice or other geological agents, including the detachment and movement of soil or rock fragments by water, wind, ice, gravity, or any combination thereof.

C. Municipal Separate Storm Sewer System - A conveyance or system of conveyances

(including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains), designed or used for collection or conveying stormwater.

D. Orem City Stormwater Inspector - Assigned City representative responsible for inspecting grading/construction activities for compliance with Erosion and

Sedimentation Control Plan.

E. Sedimentation - A process by which solid materials, inorganic (mineral) and organic, come to rest on the earth’s surface either above or below sea level.

F. Sediment - Particulate solid material, either inorganic or organic, that will settle or be deposited in a liquid under the force of gravity.

G. Orem Land Disturbance Permit (LDP) - will need to be acquired if the area of disturbance is over 500 square feet.

H. Storm Water Pollution Prevention Plan (SWPPP) Template - must be submitted to

Orem City on or before pre-construction. SWPPP templates can be found at https://deq.utah.gov/water-quality/storm-water-permits-updes-permits. If area of disturbance is over ONE acre, then a Utah Pollution Discharge Elimination System

(UPDES) Permit number will need to be acquired with a Notice of Intent submittal that can be obtained on the web link.

https://deq.utah.gov/water-quality/storm-water-permits-updes-permits

I. Waters of the State - Any and all surface and subsurface waters which are contained in or flow through the State of Utah; does not include waters in sewage systems, waters in treatment works of disposal systems, waters in potable water distribution systems, and all water withdrawn for use until use and treatment have been completed.

0.2 GENERAL

C. Erosion and Sediment Control for Construction Activity.

1. This specification governs the SWPPP that is required for all construction activities that will disturb 500 square feet of soil or larger. All earth disturbance activities in the City of Orem are regulated by the requirements of UPDES regulations.

2. All earth disturbance activities, including those that disturb more than 1 acre, must implement and maintain BMPs to control erosion and sediment pollution. SWPPP is a principal requirement of the stormwater UPDES permit. A SWPPP: Identifies all potential sources of pollution, which may reasonably be expected to affect the quality of stormwater discharges from the construction site; describes practices to be used to reduce pollutants in stormwater discharges from the construction site;

and assures compliance with the terms and conditions of the issued permit.

3. State and Federal law requires a SWPPP for all construction activity exceeding one acre. Orem City requires the SWPPP be formatted on standard 24”x36” sheets so that it can be integrated into the construction plan set. Construction activities of less than one acre will still be required to take appropriate measures to prevent sediment from entering the storm water utility system and to prevent the tracking of mud and debris onto City streets. If the area of disturbance is less the one acre, then a LDP will be required.

D. Erosion Control. Erosion controls are surface treatments that stabilize soil exposed by excavation or grading. Erosion control measures, or BMPs, provide the best means of managing sediment from disturbed lands by preventing soil movement. These BMPs are variously referred to as source controls, vegetative controls, or nonstructural controls. Some typical BMPs used to control erosion are as follows:

1. Surface Roughening – Provides temporary stabilization of disturbed areas by creating depressions in the soil surface. The depressions reduce the quantity of stormwater runoff by increasing infiltration. Surface roughening also reduces runoff velocity and provides for sediment trapping.

2. Mulching – Temporarily stabilizes soils by securely applying materials such as grass, hay, woodchips or wood fibers to the soil’s surface. Mulching protects the soil from raindrop impact and reduces the velocity of overland runoff. Mulch also aids in the growth of temporary seeding by holding seeds and topsoil in place, retaining moisture, and insulating against extreme temperatures.

3. Temporary Revegetation – The use of quickly germinating vegetative cover on disturbed areas to stabilize soils and control erosion in the short term.

4. Permanent Revegetation – The use of perennial vegetation on disturbed areas to provide long term stabilization of soils and erosion control.

5. Erosion Control Blankets – Installation of geotextiles that are used to stabilize soils, steep slopes, and drainage channels.
