It is not the intent of this manual that any standard of conduct or duty toward the public shall be created or imposed by publication of this manual. This manual is not a substitute for engineering or landscape architect, or other associated professional knowledge, experience or judgment. This manual is neither designed as, nor does it establish, a legal standard for these functions. The methods and procedures contained herein shall be reviewed by the

Engineer/Architect or other design professional using them to see that they are applicable to the project on which he/she is working. Where not considered applicable, the Engineer, Architect, or other design professional shall request a variance from these standards as provided in this manual.

The design and construction of park strips, parks, and trails and other appurtenances in the

City of West Jordan landscape, irrigation systems, park strip, parks & trails systems shall comply with these minimum standards herein called “Landscape and Irrigation Policies and

Design Criteria Manual”, or the permit requirements of various governing bodies, except where specific modifications have been approved, in writing, by the City Engineer. All submitted plans shall be stamped and signed by a civil engineer, registered in the State of

Utah, or by other design professional performing professional design work requiring their designs, studies, and contract documents to be stamped and signed, and all work shall be in accordance with good engineering and or other professional practices.

This document sets forth the minimum procedure for designing and preparing plans and specifications for park strips, parks and trails built for the City, or ones which will be dedicated to the City. Wherever there are differences between these standards and other county, state or federal regulations, the most stringent or highest requirement shall govern.

The design criteria and standard drawings contained in this document are for park strips, parks & trails only. All other policies and design criteria shall be obtained from the city’s Engineering Department.

Should you have questions regarding them, please contact the City Engineer or Parks Division of the Public Works Department.

A. Latest Industry Standards & Practices - The requirements herein are set in two major areas, irrigation systems and planting. These are set as minimum standards. These standards are not intended to limit the installation but are intended as an absolute minimum.

B. The Parks Division is willing to clarify any questions that you may have on these specifications and standards. The Parks Division will not design or engineer the project. A pre-construction meeting must be held with a representative from the Parks Division and with the landscaper prior to any work starting. If construction begins before a pre-con meeting is conducted the contractor may be asked to remove the material for inspection. A minimum of

24 hours is needed before an inspection will be conducted. The following items must be completed in order to receive a bond release on the project:

1. Parks Division must receive a set of detailed plans to be approved by the City before construction is started.

2. Current and up to date set of as-built plans for the landscape and irrigation system.

3. All punch list items must be signed off by a representative from the Parks Division.

4. Trees or plants that do not meet the planting specifications will require replacement at the contractor’s own expense. Any changes must be applied for in writing and approved in writing prior to any installation.

C. Operation & Maintenance - Operation and maintenance manuals and an "As Built" set of plans must be submitted to the Parks Division before the 7th Inspection can be considered complete. All as built plans must be an accurate computer generated copy of the entire project.

D. Streetscape Size and Location - Streetscapes and Parks shall be constructed to the sizes, grades and locations as stated in the plans approved by the City and stated herein.

E. Construction Specifications - The landscaping construction project shall include, but is not limited to, the furnishing, installing and testing of irrigation lines, backflow device and furnishing and installing of water meter(s), flow meters sprinkler heads, bubblers, drip emitters, gate valves, control valves, automatic valves, automatic controllers, field wiring, topsoil, turf, trees, shrubs, and any metered electrical connection.

M. Private versus Public Streets Policy – Please refer to the Road & Bridge Policies and

Design Criteria Manual for this information.

N. Construction Water Use Policy – All water used for any purpose is to be metered through a

City issued meter containing an approved backflow prevention device. Violation of this requirement will make the person and company subject to the City’s Municipal Code and its penalties. Check with the City’s Engineering Inspector for information on how to obtain the requirement meter.

O. Policy on Irrigation Meters - Where the parkways or side landscaping strips along streets are to be irrigated, a separate meter must be installed on each side of the street. In such cases, running an irrigation line from the meter to the other side of the street is not allowed.

Where a median strip must be irrigated, the meter may either be in the side parkway or in the median strip, providing that at either location the meter is easily accessible and protected from being covered by landscape materials or other obstructions. The Engineering

Department reserves the right to select all meter locations. It has been determined that dedicated irrigation meters are not subject to impact fees.

1.11 DEVELOPER ENGINEER’S RESPONSIBILITY

These standards establish uniform policies and procedures for the design and construction of the City park strips, parks and trails. They are not intended to be a substitute for landscape architectural, engineering, or other professional knowledge, judgement or experience. These procedures shall be reviewed by the developer’s landscape architect and/or engineer and shall be applied as necessary to the project. Proposed deviations to these standards shall be submitted by the Developer’s landscape architect and/or engineer in writing, prior to preliminary plat and or development project approval. If approved, the City Engineer will prepare an approval of the requested change.

It is the Developer and the Developer landscape architects and/or engineer’s responsibility to be aware of the City’s Parks, Recreation & Trails Master Plan for park and trails improvements and to indicate any park or trail relocations, extensions or vacations on the preliminary subdivision plat. This responsibility shall include investigating any changes from the Master

Plan necessitated by development subsequent to the Master Plan, although the above shall not relieve the developer from the responsibility to provide an approved system consistent with

Engineering Department requirements.

The Engineering Department may require that a Traffic Impact Study be completed for the project, depending upon City staff review. The Engineering Department and other City staff will review, comment on, and approve the traffic impact study. Verification of the adequacy of the surrounding roadway system rests jointly with the Engineering Department and the developer.

All plans, specifications, reports or documents shall be prepared by a licensed landscape architect and/or registered civil engineer, or by a subordinate employee under direction of the licensed architect and/or registered civil engineer. Each of these documents shall be signed and stamped with a professional landscape architect and/or engineer seal, to indicate responsibility for them. A wet stamp is required on all documents except reproducible plans, where a stamp on the original is acceptable.

A “Preliminary Review” and or “Released for Construction” stamp or signature of the City on the plans does not in any way relieve the developer’s engineer of the responsibility to meet all requirements of the City, or the responsibility for preparing the studies, designs, and other activities associated with these “Released for Construction” drawings and/or other contract documents. The plans shall be revised or supplemented at any time if it is determined that the

City’s requirements have not been met.

Generally, plans that are signed as being released for construction will not require revisions based upon subsequent revisions to these standards, however, when the Engineering

Department’s opinion, a change to the project is necessary, based upon a significant change in the standards, which significantly affects public safety, future maintenance costs, or similar concerns, such a charge may be required during construction by the City Engineer. Changes may also be required in the case where a developer does not proceed to construction within the time allowed in the agreement with the City.
