1.9 Policies
The following policies also apply to private development projects and CIP projects alike. Should you have questions regarding them, please contact the City Engineer or Parks Division of the Public Works Department.
- 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.
-
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:
- Parks Division must receive a set of detailed plans to be approved by the City before construction is started.
- Current and up to date set of as-built plans for the landscape and irrigation system.
- All punch list items must be signed off by a representative from the Parks Division.
- 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.
- 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.
- 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.

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.

Section 3.0 Materials
3.1 General Requirements
This section discusses the materials involved in parks irrigation water pipeline distribution systems and associated construction activities. The materials selected have been chosen for their strength, durability and ease of maintenance. All materials, unless specifically approved otherwise, shall be new and unused.
Where applicable, American Water Works Association (AWWA) or other standards have been referenced and it shall be the responsibility of the developer/engineer/contractor to be familiar with those standards to insure compliance. Titles corresponding to the specific numbers are given in the reference section of the standards.
In some instances, particular manufacturers and product names have been mentioned as being approved. Other products may also meet the requirements but must first be approved by a Products/Materials Committee consisting of Engineering and Public Works staff and any other affected departments. The Committee will meet and make a recommendation to the City Engineer who will issue a decision in writing. One factor, which may be considered by the Engineering Department in any consideration of other products, is the need for some degree of standardization.
If at any time the Engineering Department believes that the use of a specific product must either be halted or changed, the City Engineer has the authority to make the change providing the decision is based upon an engineering, performance or maintenance evaluation.
3.2 Testing and Final Acceptability of Material
The Engineering Department will require such tests and certifications as deemed necessary to show that the specified materials have been employed. Notwithstanding prior factory or yard inspections, the City Engineer will have the right to reject any damaged or defective materials found on the job, which will affect the durability or performance of the installation and order its removal from the site.
3.3 Main Line Pipe Materials
General accepted main line pipe materials consist of either polyvinyl chloride (PVC) or ductile iron pipe (DIP) as described in this section. All materials which may contact drinking water shall be ANSI – certified as meeting the requirements of ‘NSF Standard 61, Drinking Water System Components’. All pertinent water system components should be appropriately stamped with the NSF logo for field verification. The following pipe materials and sizes apply to work within the City of West Jordan water service area:
| Pipe Diameter (inches) | Pipeline Type |
|---|---|
| 8, 10, 12 | PVC or Ductile Iron |
| 16,18,20,24 | Ductile Iron |
| 24 and above | Ductile Iron |
- PVC Pipe – All materials which may contact drinking water, including plastic pipes, gaskets, lubricants and O-rings shall be ANSI – certified as meeting the requirements of ‘NSF Standard 61, Drinking Water System Components’. All pertinent water system components should be appropriately stamped with the NSF logo for field verification. Please refer to the City’s ‘Construction Specifications Manual’ for detailed information regarding this pipe type.
-
Ductile Iron Pipe. – The City allows the use of this pipe type for main lines which meet the following requirements:
- Pipe. The pipe shall conform to AWWA C151 for both quality and strength. Each pipe shall include the letters “DI” or word “DUCTILE” to indicate the pipe material.
- Joints. These shall be of the rubber gasket push-on joint type conforming to the requirements of AWWA C111 and being of the “tyton” type.
- Fittings. All fittings shall conform to AWWA C110.
- Lining and Coating. Unless otherwise approved, the internal surfaces shall be lined with a uniform thickness of cement mortar and then sealed with a bituminous coating in accordance with AWWA C104.
Outside protective coatings are dependent upon the soil type in which the pipe will be buried. The engineer is to evaluate this issue and provide a recommendation along with backup information to the City Engineer for review and approval.
Construction of this pipeline type may require full-time inspection from off loading of the material to completion of testing.
3.4 Main Line Fittings
-
Ductile Iron Fittings. These fittings shall meet the requirements of AWWA C110. All fittings shall be rated for 250 psi. These standard covers but are not limited to fittings with combinations of ends including mechanical joints, plain end, flange, push joint. The fitting types are as follows:
90, 45, 22-1/2, and 11-1/4 degree° bends
Tees and crosses, reducers, caps and plugs, connecting pieces (MJ sleeve and MJ adapters), flanged bends, flanged tees and crosses, flanged reducers.
Ductile-iron compact fittings, per AWWA C153, are allowed. It should be understood that care must be exercised to not mix mechanical and flange joint ends since they will not mate. Bolt ends shall be coated with Poly FM grease and each fitting wrapped in 10-mil Polyethylene sheeting after installation.
- Flanges, Bolts and Gaskets. They shall be flat-faced and meet the requirements of AWWA C207 and should be AWWA standard steel hub flanges, Class E (275 psi) (these flanges meet ANSI B-16.5). The flanges shall be marked with the size, name or trademark of manufacturer and with the AWWA class, i.e. “E”. Bolts and nuts are to be provided as indicated in the City’s ‘Construction Specifications Manual’. Gaskets shall be of the drop-in gasket type, 1/8-inch thick.
| Pipe Size (inch) | Bolt Hole Dia. (inch) | Bolt Dia. and Length (inch) | No. Of Bolts |
|---|---|---|---|
| 8 | 7/8 | ¾ x 3-1/2 | 8 |
| 10 | 1 | 7/8 x 4 | 12 |
| 12 | 1 | 7/8 x 4 | 12 |
| 14 | 1-1/8 | 1 x 4-1/2 | 12 |
| 16 | 1-1/8 | 1 x 4-1/2 | 16 |
| 18 | 1-1/4 | 1-1/8 x 5 | 16 |
The inherent problem with flanges is that they are rigid and do not provide flexibility. Two keys to their installation are (1) uniform tightening of the bolts, and (2) prevention of bending or torsional strains. Proper anchorage is important to meet the latter objective
- Mechanical Joint Fittings. This is a bolted joint of the stuffing box type. Each joint has a bell provided with an exterior flange having bolt holes or slots, and a socket with gaskets to receive the plain end of the pipe or fitting. The joint also has a sealing gasket, follower gland with bolt holes and tee head bolts with hexagonal nuts. The mechanical joints shall meet AWWA C111. That standard covers the joint as well as gaskets and bolts.
| Pipe Size (inch) | No. Bolts | Bolt Diameter & Length |
|---|---|---|
| 8 | 6 | ¾ x 4 |
| 10 | 8 | ¾ x 4 |
| 12 | 8 | ¾ x 4 |
| 14 | 10 | ¾ x 4-1/2 |
| 16 | 12 | ¾ x 4-1/2 |
| 18 | 12 | ¾ x 4-1/2 |
- Flexible Couplings. These are designed to connect plain end pipes with a mechanical Compression joint to provide a stress relieving, flexible, leak proof joint. They can be ordered in steel or cast-iron pipe sizes (note: C900 PVC pipe has same O.D. as cast iron).
- Transition Couplings. These are used to connect pipes of the same nominal size but different materials. Steel and PVC pipes can be connected to one another.
- Flanged Coupling Adapters. These are used to connect plain end pipe to flanged valves, pumps, meters, etc. They eliminate the need for both a flanged spool and coupling. Generally, they are available in sizes through 12-inches.
- Insulating Couplings. These are used to stop the flow of electric current across the joint by means of an insulating boot.
- Special Steel Pipe Fittings. AWWA C208 covers special fittings such as elbows, tees, crosses, reducers, etc., and should be consulted for a specific application.

The specific requirements of each of these categories are discussed in greater detail in the following subsections.
-
Plan Submittal –
Engineers submitting plans to the City for initial screening are to provide:
- Five (5) sets of complete plans (check prints) sealed by a licensed landscape architect for the landscaping and irrigation plans, and by a registered Engineer in responsible charge for any civil work required for the project.
- One (1) copy of the completed bond estimate form with quantities for all public improvements, also quantities should be shown on construction plans.
In addition, the following items are required as part of the initial review submittal:
- Two (2) copies of the geotechnical soils investigation report if the project includes construction of public streets. The report must include a pavement section recommendation for all proposed public streets.
- Verification of traffic impact analysis (TIA) submittal to the traffic engineer if a TIA is a condition of approval.
- Verification of drainage study submittal to Engineering Department if a drainage study is a condition of approval.
- When a project requires grading or construction off-site, One (1) copy of a notarized authorization from every private property owner on whose property work is required.
- Written notice of deviations. If the plan submittal contains deviations from either these guidelines or the requirements of the uniform standards and City policy, the design engineer is to as part of the initial submittal include a letter to the City outlining all deviations and substantial reasons for requesting the deviations.
In addition to the items outlined above the Assessor’s Parcel Number (APN#) is to be placed on the cover or title sheet of the submittal. Fire flow information is to be placed on the water plan if a structure is involved and secondary water information is to be placed on the master utility plan.
All initial submittals are reviewed for conformance to the Engineering Department initial plan screening checklist. Failure of the design architect/engineer to include the required information with the initial submittal will result in rejection of the plan submittal and the return to the design architect/engineer. If the submittal contains sufficient information to be processed for review, the submittal will be accepted, and both the design architect/engineer and developer will be notified. Following the initial plan screening, the five plan sets submitted will be circulated to various sections within the City for review and comment. The initial review will take from 3 to 4 weeks with redline reviews taking a week to return. When comments are received from the other City reviewing groups, the Engineering Department will consider the comments and review the plans for conformance to City standards. The Engineering Department will transmit the review comments to the design architect/engineer and either request the plans be resubmitted for review or that mylars be submitted following corrections.
-
Resubmittal –
If the conditions of approval or the Engineering Department require a drainage study or traffic impact analysis, those studies are to be approved prior to resubmittal of the improvement plans to the Engineering Department.
Engineers resubmitting plans to the City for review are to provide:
- All plans as requested from the initial review shall be submitted electronically by the Architect/Engineer in responsible charge.
- One (1) copy of the initial plan review comments (redlined plans).
- Verification of Traffic Impact Study (TIS) approval by the Engineering Department if a TIS is a condition of approval.
- Verification of drainage study approval by Engineering Department if a drainage study is a condition of approval.
- Design engineer’s certification that the grading plan is in conformance with the approved drainage study.
- Design engineer’s certification that the plans are in conformance with the approved traffic impact study, if required.
Plans resubmitted to the City for subsequent review are to address all previously made land development review comments. The design engineer is to certify the grading plan conformance to the approved drainage study with the initial resubmittal and subsequently thereafter. All redesign from the previous submittal is to be clearly identified. In the event of major changes or significant redesign from the previous submittal, the design architect/engineer should contact the Engineering Department to schedule a meeting to discuss the redesign concurrent with the resubmittal. Failure to meet with the Engineering Department to resubmitting a major redesign may delay the plan process.
Each resubmittal review process takes 7 working days. After reviewing the plans, the Engineering Department will either return the plans to the design architect/engineer to address comments or request that original and duplicate Mylars be submitted to the City for approval.
- Required Easements and Rights-of Way – When improvement plans indicate easements to be dedicated or rights-of-way granted a complete package must be submitted prior to approval of the plans. This package must include legal descriptions, 8 ½ by 11 sketch and current vesting document. Easements may include ingress/egress, drainage, sewer, and intersite easements.
- Final Submittal and Plan Approval – Improvement plans for projects cannot be approved until after the final plat is approved. Prior to submitting original mylars and duplicate mylars to the Engineering Department for approval, certain prerequisite items must be submitted to and approved by the City. As part of the initial plan submittal the design architect/engineer is required to submit a complete bond estimate form. This form is reviewed and if it is deemed accurate with no major design issues outstanding, an approved bond estimate form will be provided to the design architect/engineer. The process of completing the bond estimate and obtaining the required bond estimate form is the responsibility of the developer and should be commenced early on in the process.
-
Request for Deviation Procedure –
All deviations from these guidelines, the uniform standards or City policy are to be submitted to and approved by the Engineering Department. There are two types of deviations the engineer may need to address during the design process. First, deviations from the guideline requirements. All deviations from the guidelines are to be listed and submitted with the plans and other documents identified in “Initial plan submittal”. Upon receipt, the deviation listing will be reviewed by the plan screener and supervisor. If the deviations are deemed to have merit, the plans will be screened and either accepted or rejected. If the deviations are considered to be only for the convenience of the design architect/engineer, the Engineering Department will review the deviation request. If the Engineering Department considers the deviations acceptable, the plans will be screened and either accepted or rejected. . If the plans are rejected and the design architect/engineer desires to appeal the decision, the appeal is to be made in writing to the City. Upon receipt of the design architect/engineer appeal, the architect/engineer will schedule a meeting with the design architect/engineer and the City staff engineer. The purpose of the meeting is to allow the design architect/engineer the opportunity to present its case to support the request. Within five working days following the appeal meeting, the Engineering Department is to inform the design architect/engineer of its decision. The decision of the Engineering Department is to be final at this time.
The second type of deviation is a deviation from the requirements of the uniform standards and/or drawings or City policy. The architect/design engineer is to identify and request a deviation from standards in writing and submit the request along with the other documents required in subsection 4.7.B., “Initial plan submittal”. If the deviation is deemed to be in the best interest of the City and the project, the plans will be allowed to proceed through the plan review process. If the deviation as requested is determined to be unacceptable to the City, the Engineering Department is to schedule a meeting with the design architect/engineer to attempt to resolve the issue. If the deviation is rejected and the design architect/engineer desires to appeal the decision, the appeal is to be made in writing to the City Engineer. Upon receipt of the design architect/engineer appeal, the City Engineer will schedule a meeting with the design architect/engineer and the City staff engineer. The purpose of the meeting is to allow the design engineer the opportunity to present its case in support of the request. Within five working days following the appeal meeting, City staff engineer is to inform the design architect/engineer of his decision. The decision of the City Engineer is to be final. If the denial of a deviation from standards or City policy will significantly impact a project, the design architect/engineer is to contact the Engineering Department to review and resolve the design issue prior to making the initial submittal.
- Plan Setup Requirements – The City’s Engineering Department is required to be the custodian of all improvement plans in perpetuity once they are approved. As the City moves to archiving plans on electronic media it is important that some degree of uniformity is maintained. The objective of the following plan setup requirements is to provide uniformity and standardization of plan submittal while allowing the design engineer flexibility with respect to presentation. Standardization of information along with uniformity in setup and presentation allows the review process to occur in a more orderly and timely fashion.
- Plan Sheet Size – All plans submitted to the City of City of West Jordan must be signed and sealed by a licensed landscape architect and civil engineer who are registered in the State of Utah. Plans are to be plotted or drafted onto Mylar reproducible sheets and having an overall size of 24- inches wide by 36-inches long with margins placed accordingly. One and one-half inches on the left side and ½-inch on all remaining sides with a line thickness of 0.075 inches.
-
Title Block –

- Benchmark – All projects are to utilize and reference an existing recorded City benchmark datum within one-quarter mile of the project site. If an existing benchmark is not located within the one- quarter mile limit, a temporary benchmark on the project site suitable for the project construction/inspection purposes is to be established and referenced to the City datum. Every plan sheet to be utilized for construction of improvements is to indicate the referenced benchmark.
-
Drawing Scales –
Drawing scales are to be a minimum of one-inch = forty feet (40’) horizontal for plan views, unless otherwise noted in these guidelines. Drawing scales are to be a minimum of one inch = 40-feet horizontal, one inch = 4-feet vertical for plan and profile when slopes are less than 5 percent and a minimum of one inch = 40-feet horizontal, one inch = 8-feet vertical for plan and profile when slopes are greater than 5 percent. Plan and profile sheets are to be arranged such that the plan view is in the top half and the profile view is in the bottom half of the sheet. Profiles are to have vertical lines at every 50-foot station and horizontal lines at every 4-foot elevation.
All details are to be drawn to scale. The horizontal and vertical scale need not be the same. The purpose of requiring details be presented at scale is to allow the plan reviewer the ability to see spatial relationships of the various elements in the detail.
-
Plan Orientation –
Generally, in lying out and developing the design, the design engineer is to consider the following hierarchy in establishing plan sheet orientation;
- North should be to the top or right of the sheet.
- Stationing is to be left to right unless the sheet orientation with respect to North will not permit. The image is to only be drawn on the front side of the Mylar.
- Text Size and Line Weights – The final criteria for acceptance will be that all information provided on the plans be clear, concise and legible when the 24-inch x 36-inch sheet drawing is reduced to an 11-inch x 17-inch format. The following text size and line weight references are recommended for clarity but are not required. All text, which includes but not limited to dimensional text, spot elevations text, notes and other text are recommended to be Leroy (L80) or romans.

Data that must be presented and should not deter the design architect/engineer from providing additional information as may be required. In the event the design engineer believes that the requirements of these guidelines are not applicable to a specific site or condition, the engineer is to request a deviation from the City. To facilitate the plan review and construction process, the City prefers that certain information be placed in a specific location on given sheets. The preferred location is identified in bold italics following the item description.
Example: North Arrow (upper right quadrant of sheet)
The above example indicates that the preferred location for the north arrow is in the upper right quadrant of the plan sheet. The City realizes that on rare occasions it may not be possible for the design engineer to comply with the City information placement preference. In those instances, the design engineer needs to identify all deviations from these guidelines in writing and submit the deviation listing to the City in accordance with, “Request for deviation procedure”.

5.0 Plan Review & Approval
5.1 General
-
General – The process of City staff review and correction of Developer provided
landscaping & irrigation ‘Released for Construction Drawings (RFCD)' is discussed in
this Section. The review of these RFCDs has been less defined in the past, the purpose of this document is to outline what needs to be prepared, reviewed, and who does that work. Building elevations, plats, site plan drawings, construction drawings for other public infrastructure, reports, studies, calculations, and other documents used in the processing of
a private development project through the City will be address in other Manuals. The process of reviewing these RFCDs is called the ‘Redline Review Process’. ‘Redlines’ refer to those handwritten corrections, usually written in red pencil or pen, on RFCDs, and other hand-written or typed documents, which provide direction to the Developer and
his/her engineer/architect on what items need to be changed on these documents. They also include written documentation of alternatives the Developer might consider in order to meet the City’s requirements, or optional suggestions the Developer might wish to consider in finalizing his/her project.
The process is initiated by the Developer submitting all of the RFCDs and required documents the City has indicated are necessary for the review of this specific project. All of the RFCD documents required by the City must be provided at the time of submittal after application, or the City staff will return the submitted materials back to the
Developer, mark those documents that are missing on an appropriate checklist, and require that the Developer obtain the other documents prior to submitting the application packet back to the City. City staff will inventory the documents to ensure all of the documents are present, and the City’s Project Review Team will complete the detailed
review of the documents later. The City’s project planner, engineer, Public Works staff, and other City staff involved in the review of the RFCDs are referred to as the City’s ‘Project Review Team’, and they will be responsible for reviewing the RFCDs and processing them through the City.
-
Purposes of Redlines – The purposes of the ‘Redlining’ process are as follows:
-
Explain and clarify the City staff’s comments regarding various documents they
have reviewed which were provided to the City staff for review as part of the
private development project.
-
Create documentation, which sets the standard for what will be required of the
project, in order for it to be processed through the City.
-
-
Types of Comments – Redline comments come in three distinct types, they are:
-
Comments Required to meet Code, standard, manual or other Planning
Commission and/or City Council conditions or approved requirements – These
are comments the Project Review Team will make on ‘redline’ documents which are required by the City of West Jordan Municipal Code, standards, manuals, or other Planning Commission or City Council approved documents. These are required to be complied with by the Developer and his/her engineer and other
professionals and are not optional for them to consider. If the Developer wishes to contest these requirements, they must be done through the appeal process set forth in ‘Section 5.8 – Developer’s Appeal Process’ of this Section, and or the Municipal Code. City staff does not have the authority to waive or change these
requirements.
-
Alternatives for Code, standard, manual or other Planning Commission or City
Council approved requirements – There are situations where a given project may
have alternatives City staff may indicate are available to the Developer to meet City Code, standards, or manual requirements. These will be indicated in a separate ‘Project Redline Memorandum’ which will detail the alternatives available to the Developer, along with any other information City staff may wish
to communicate to the Developer for his/her consideration. It the responsibility of the Developer to weigh and select a given alternative and indicate so in writing to the Project Review Team. The project will not proceed with further review until the Developer provides this written decision.
-
Optional suggestions – There may also be optional suggestions the Project Review Team wishes the Developer to consider in the remaining preparations for the project. These will also be included in the ‘Project Redline Memorandum’ and will be included under the heading of ‘Optional Suggestions’. The Developer
must provide a written response to whether these suggestions will be included in the project and can be included with the ‘Alternatives for Code Compliance’ items.
-
-
Types of Redline Documents – ‘Redline Documents’ typically include ‘Released for Construction Drawings’, studies, reports, calculations, and any other type of document
which may be submitted to the Project Review Team in order to adequately address City requirements for a given project. The Project Review Team will mark on these ‘Redline
Documents’ any corrections, which may be necessary to meet City requirements. Redline comments are to be prepared after reviewing the City’s Municipal Code, standards, and manuals.
-
All Redlines Must be Addressed in Order to Process Project – The Developer needs to note that all redlines must be addressed to the satisfaction of the City staff before the City
Planner and City Engineer will schedule the project for Planning Commission or City Council review.
-
Private versus Public Projects – In the case of landscaping and irrigation ‘Released for Construction Drawings’, a project may contain both landscaping and irrigation areas
which will ultimately be dedicated to the City for the City’s operation and maintenance. In such cases we will designate as ‘public’, and landscaping and irrigation areas which
will be maintained by private entities or individuals, these we refer as ‘private’. Both ‘public’ and ‘private’ areas of landscape and irrigation are subject to the same level and quality of design, materials and workmanship. Both will have bonding requirements, but once the areas are acceptable to the City and eventual long-term owners, the bonds will
be released per code, and they will then be maintain by the City, if they are ‘public’, and by private entities, if they are ‘private’.
-
Irrigation Water Meters – Design, specifying, and construction of water meters for landscaping and irrigation projects are subject to a separate Manual, the ‘Water Policies
& Design Criteria Manual’. Pleases refer to this Manual when dealing with water issues. All of the information needed is contained in this document. It should also be
noted that it has been determined that no water impact fee will be required for water meters which provide solely for a separate irrigation service.
5.2 ‘Released for Construction Drawings’ Receipt and Distribution Process
Once the Developer delivers his projects ‘Released for Construction Drawings’ to the City, they will then be distributed to various departments for review and comment. This includes the
Engineering, Community Development, Public Works, and Fire departments. If the project is a commercial project, it will also be distributed to Utah State University for a water conservation
compliance review. The entire RFCD set of drawings will remain in one stapled set, and drawings will not be removed for separate review. Six (6) sets of RFCD are required to be submitted to the Office of Development Assistance (ODA), who will then have the ODA Project Manager distribute these 6
sets. Three (3) sets of RFCD will go to the Engineering Department, and 3 sets will be given to the Community Development Department for processing. Please see the following flowchart for additional information regarding the distribution and review of the RFCD.

5.4 Project Review Team’s Responsibilities in the Redline Review Process
The Project Review Team is responsible for reviewing the documents submitted by the
Developer in accordance with the established Municipal Code, standards, policies and design
criteria manuals, specifications, the Development Processing Manual, and any other City Council approved documents meant for this purpose. The Project Review Team will mark on the drawings, studies, or reports, any corrections that are necessary in order for the project to meet the requirements indicated above. The Project Review Team will indicate the Code,
standard, or manual requirement, which applies to the comment. If the Developer does not agree with the Project Review Team’s interpretation of regulations, or wishes to challenge the requirement, the Developer needs to understand that City staff does not have the authority to waive, or not enforce these requirements. These are City Council approved requirements, and
only the City Council can change or alter the requirement. The Developer will need to follow the appeal process outline in ‘Section 5.8– Developer’s Appeal Process’ or Municipal Code appeal process. In addition to the ‘redline’ marking of ‘Released for Construction Drawings’, or other studies
and reports, City staff will also provide a separate hand-written or typed document called a ‘Project Redline Memorandum’, which provides alternatives to the Developer for meeting the City’s codes, standards or manuals. The review will be based on code, general plan, standards and
specifications. As part of this effort, the Project Review Team will provide a written description of what the alternatives are, any concerns that City staff may have regarding the alternatives, pros and cons they may be aware of, and other items which may be useful in the Developer’s decision on which alternative to select. The Developer will then choose the course
of action he/she wishes to follow. The Developer must indicate, in writing, to the Project Review Team which alternative he/she elects to select. The project cannot be further processed until the Project Review Team receives this document. City staff may also elect to provide ‘Optional Suggestions’ they wish the Developer to consider
in finalizing the project. These will be included in the ‘Project Redline Memorandum’ under the heading of ‘Optional Suggestions’. The Developer is not required to include these suggestions in the next version of corrected documents for the project, but must provide in writing, an indication as to whether he/she intends to include them in the project.
City staff’s responsibility is to be as clear as possible in defining the issue(s) for the Developer, so the Developer and his/her engineers/architects understand the issue(s), and what the resolution to the issue(s) may be. Typically there will be one to three ‘redline reviews’ produced for a given project, unless the Developer and his/her engineer/architect are not
adhering to the ‘redline’ comments, and additional ‘redlines’ are required. If the Developer’s project requires more than 3 sets of ‘redlines’, the Developer will be charged extra for the review of these additional sets of ‘redlines’.
5.5 Developer’s Responsibilities in the Redline Review Process
The Developer and his/her engineer/architect have responsibilities for making the ‘redline’ process a productive and efficient effort.
The first responsibility the Developer and his/her engineer/architect have in the process is to understand the City’s general plan, codes, standards, manuals and other documents, and that the project is planned and designed in accordance with these documents. If the Developer and his/her engineer/architect are not familiar with the City’s requirements, the project will
not be able to be processed as quickly as it would, if there aren’t extensive ‘redlines’ to the project documents. The Project Review Team has extensive experience in these types of reviews and will ‘redline’ all deficiencies and require they be changed to meet City requirements prior to further processing the project. Not following these guidelines will
result in delays to the Developer and his/her project. The Developer has the responsibility of making the corrections noted on the ‘redlines’ if they are City code, standards, manuals, or other City Council approved documents comments. These corrections are not optional and are required to be made. If the Developer disagrees with these requirements, the Developer
is required to indicate this disagreement in writing to the Project Review Team, once the Developer has received and reviewed the ‘redlines’. ‘Section 5.8 – Developer’s Appeal Process‘must be followed in resolving these types of issues. Possible modification of project requirements/agreements are closed once the Planning Commission and/or City Council
approve the project. If modifications are requested, the plan or application must go back to the Planning Commission and/or City Council for modification. The Developer has the responsibility to respond to alternatives for code compliance contained in the ‘Project Redline Memorandum’ in writing. The Developer is required to consider the
alternatives and then select one for implementation into the project. City staff may indicate a list of items available for the Developer to consider in this process, but the decision to select one alternative over another is solely for the Developer to make. The Developer has the responsibility to consider optional suggestions but is not required to
comply with these suggestions. The Developer does have the responsibility of responding to Project Review Team about whether he/she intends to implement these suggestions into the project. The Developer and his/her engineer/architect have the responsibility of being as clear as
possible in responding to the concerns expressed by the Project Review Team on the ‘Redline Documents’, so the Project Review Team understands the Developer’s concerns, and what the Developer’s proposed resolution to the concern(s) may be.
5.6 Types of Redline Documents
-
Building Elevations – One of the documents which may be redlined are the building elevations, if a pavilion or other such structure is associated with the landscape and
irrigation project. These drawings depict the appearance of the structure from various vantage points and provide the Developer and City staff an opportunity to review the outward appearance of the structure to ensure it meets the City’s codes and other requirements.
-
Released for Construction Drawings – These are specific drawings produced by engineers and architects, and used by engineers, contractors, and others in the actual construction of the project. They consist of a number of different types of drawings as indicated in Table 5.3.1. The City requires that ‘Released for Construction Drawings’ be provided and
followed in the construction of approved projects.
-
Studies and Reports – Projects may require the preparation of various types of studies and
reports in order to quantify issues related to the project. These may include geotechnical
reports, geologic reports, traffic impact studies, drainage studies, development plans, modifications of various master plans, etc., which may be required for the individual project. The Project Review Team will identify which reports are necessary at the beginning of the project and may require additional studies/reports as work on the project
progresses.
-
Other Types of Documents – Each project is unique and may require other types of
documents to be submitted for the project to be processed. As the project is processed
through the City, the documents will become evident and will be indicated to the Developer by the Project Review Team.
5.7 Redlines
The Project Review Team will provide responses to the Developer’s project submittals in three different forms. These are:
-
Project Redline Memorandum – In every case, the Project Review Team will assemble a ‘Project Redline Memorandum’ which indicates the status of the project and provides code
requirements, ‘Alternatives for Code Compliance’ issues, ‘Optional Suggestions’, and any other comments the Project Review Team feels will help the Developer revise the ‘Redline
Documents’ and allow them to be further processed. The Memorandum may or may not include the items listed above, depending upon the needs of the specific project. This Memorandum will act as a summary of the ‘redline’ effort by the City staff.
-
‘Redlined Drawings’ – Most projects will contain some type of drawing or drawings. The Project Review Team may mark on these drawings any changes they wish to see
made, as long as the comments were identified as ‘code requirements’, ‘alternatives’, or ‘Optional Suggestions’, or they may include this discussion in the ‘Project Redline Memorandum’.
-
Other Redline Documents – There are a variety of these types of documents and the Project Review Team may mark on these documents or may include a summary of concerns in the
‘Project Redline Memorandum’. The Developer needs to check all documents for comments, which are returned to the Developer from the Project Review Team.
5.8 Developer’s Appeal Process
The ‘Appeals Process’ to the Project Review Team’s conditions and corrections as part of the ‘Redline review process’ is contained in the City’s Municipal Code.
It needs to be noted that the appeals process will take time and will delay the Developer’s project until a resolution of the issues can be finalized.
5.9 Landscaping and Revegetation Bonds
Separate landscaping and revegetation bonds are required for these types of projects and are further described in Title 72 – Public Works, Chapter 10, Part 3. Public Improvement
Guarantees. Please keep in mind that the landscaping and revegetation bonds have different requirements and release time periods than those of the normal public improvement bond.

7.0 Construction Inspection
7.1 Introduction
- General – The construction of a project which includes public and/or private landscaping and irrigation systems is designed, reviewed, approved, inspected and accepted by several different departments within the City. The review and approval process are best defined by reviewing Table 5.3.1 – Drawing/Code Review and Responsibility for Review. As you will see, the Engineering, Community Development, Public Works, Fire Department, and Utah State University all have responsibilities for the review and approval work required for the landscape and irrigation portions of these projects. The same thing applies for construction inspection and acceptance of the landscape and irrigation systems portions of these projects. Below is a table which indicates which department is responsible for what inspection and approval.
The table contains three categories which need additional explanation. These include the “Released for Construction Drawings” Responsibility/Inspections, Milestone Inspections, and Other Issues/Inspections sections of the table. Developers and Contractors need to make special note of the various responsibilities and inspection requirements so that time is not wasted.
The “Released for Construction Drawings Responsibility/Inspections” portion of the table indicates which department has primary and secondary responsibility for issues related to these individual sheets of the “Released for Construction Drawings” set of drawings. If there are issues or concerns related to these sheets, these departments will address these concerns.
The “Milestone Inspections” section of the table is included to indicate specific inspections which must be scheduled and passed prior to moving on to the next phase of work. Please contact the department indicated at least 24 hours in advance, prior to needing these inspections. If the Developer or his/her Contractor cover up work, or move on to the next phase of work, the Contractor will be required to uncover his/her work so that it can be properly inspected as indicated.
The “Other Issues/Inspections” portion of the table provides information regarding who to contact should the Developer or Contractor have questions during construction. These items also need to be addressed to go into the Warranty period or come out of the Warranty period and some bond releases.

- Flow rate in gallons per minute
- Precipitation rate in inches per hour, sprinklers only
- Run times in minutes per day
- Number of water days per week
- Cycle time to avoid runoff
8.0 Post-Construction Monitoring
8.1 Irrigation Audit
A. Irrigation Audit – This requirement applies to all landscapes measuring over 1,000-square feet. Following construction and prior to issuing the city ownership of the property, an irrigation audit shall be conducted by an Irrigation Association Certified Landscape Irrigation Auditor (CLIA) who is approved by the City. The auditor shall be independent from the contractor, design firm, and owner/developer of the project. The irrigation audit will verify that the irrigation system complies with the minimum standards required by this ordinance. The average distribution uniformity for all tested turf zones (valves) must be at least 60% for fixed/sprays zones and 70% for rotors/stream zones. All turf zones (valves) shall be tested for distribution uniformity, up to a maximum of eight (8) zones. When the irrigation system consists of more than eight (8) zones, the auditor shall select and test eight (8) turf zones, including both fixed and rotor zones, which are most representative of the system. All other zones, including drip irrigation, micro spray, bubblers, or other designs, shall be turned on and inspected visually for head placement, head adjustment, appropriate gallon-per-minute emitters, pressure problems, leaks and general coverage.
When the above audit is required, the auditor shall furnish a report to the City and owner/developer certifying compliance with the minimum requirements. Compliance with this provision is required before the City will issue the certificate of occupancy.
9.0 Public Improvement Bonds Process
9.1 General
The purpose of this section is to address issues related to the “Public Improvement Bond” and its various parts. There are four main parts to this process which include:
- Bond preparation and approval
- System bond reductions
- Warranty inspection/bond reduction
- Final inspection/bond release
The “Public Improvement Bond” consists of processes as shown below:

9.4 Developers Role
The Developer has the primary and an integral role in the preparation, establishment, reduction and release of the improvement bonds. These responsibilities include:
- Bond Estimate Sheet(s) – The Developer and his/her engineer, is to submit to the Engineering Department a complete bond estimate sheet(s), on the forms provided by the Engineering Department. The Developer is responsible for submitting a reasonable listing of public improvements, landscaping and non-public improvements in common areas.
- Bond Agreement Form Preparation – The Developer is to submit a bond agreement in the form of a Letter of Credit, Escrow Deposit, Surety, or Cash. The bond agreements are available on the web at www.westjordan.utah.gov or at the City of West Jordan, which is to be approved by the City Attorney Office.
- Developer/Contractor Certification for Bond Reduction/Release – The Developer is responsible for understanding and being involved with the progress on construction of his/her project, prior to submitting a written bond reduction or release request. Many times, the Contractor indicates he is ready for a bond reduction or release, when this is not the case. As such, the City has prepared a “certification form” for the various “systems,” which the Developer and his contractor are to complete as part of the written reduction/release request. This form must be properly completed and submitted to the Engineering Department before the Engineering Department inspection staff will initiate an inspection of the “system,” for which a reduction/release is being requested. Once the “certification form” is completed and submitted, an inspection by engineering staff will be promptly completed. If it is found during the inspection that the “system” is not ready for inspection, the Engineering inspector will return a written response to the Developer indicating the items that are not complete. Subsequent inspections after the first inspection will be billed to the Developer on an hourly rate basis.
- Timely Completion of Corrections List (Punchlist) – Once an inspection has been conducted by the Engineering Inspector, and a Corrections List (Punchlist) has been completed, the Developer and his Contractor are responsible for making the required corrections and notifying the Engineering Inspector that the corrections have been made within 30-calendar days, or the Corrections List becomes null and void and a new Corrections List will be required to be prepared. Additional inspection work required of the Engineering Inspector will be charged to the Developer for this additional work.
9.5 City Role
The City has an integral role in the review of the preparation, establishment, reduction and release of bonds. These responsibilities include:
- Bond Estimate Sheet – The Engineering Department will review and either return the bond estimate sheet to the Developer and his/her engineer for additional work, or will approve the draft bond estimate sheet for further processing.
- Bond Agreement Form – The City Attorney’s Office (CAO) is responsible for the review and approval of the bond agreement form.
- Bond Estimate Unit Prices – The City Engineer is responsible for revising the City’s bond estimate unit prices on at least a yearly basis (January or every year). The City Engineer may revise the bond estimate unit prices on a more frequent basis in cases where it is deemed necessary.
- Developer/Contractor Certification for Bond Reduction/Release – City staff will review the “certification form” and perform an inspection on the “system” and will provide the Developer and Contractor a written response regarding their request within 7-days.
- Timely Completion of Corrections List – Once the Developer has submitted a written indication that the Corrections List is complete, the Engineering Inspector will inspect the project again in relation to the Corrections List. The Engineering Inspector will provide a written response within 7-days as to whether the corrections list was completed, or whether items were not completed.
9.6 Bond Document Preparation and Approval
The Developer has primary responsibility for bond document preparation and submission to the City. The bond documents preparation process is described as shown below:
A. Developer Engineer’s Bond Estimate Preparation
The first step in the preparation of the bond documents, is the Developer’s preparation of a draft bond estimate sheet. This is accomplished by obtaining a blank sheet from the City Engineer, and using the finalized released for construction drawings for the project to prepare a draft bond estimate for the project. This document is to be stamped and signed by the Developer’s engineer and submitted to the City Engineer for his/her review and approval. The Developer is responsible for submitting a reasonable listing of public improvement, landscaping and non-public improvements in common areas.
B. City Staff Review of Bond Estimate
The engineering department will review and compare it against the released for construction drawings. The bond estimate will either be returned the developer for additional work or will be approved for further processing. The Developer is responsible for ensuring the necessary corrections are made and the document returned to the City Engineer for approval.
C. Developer Submission of Bond Agreement
The Developer is to submit a bond agreement in the form of a Letter of Credit, Escrow Deposit, Surety, or Cash. The bond agreements are available on the web at www.westjordan.utah.gov or at the City of West Jordan. The bond agreement is approved by the City Attorney Office.
The bond agreement guarantees the installation of public and non-public improvements. These are discussed below:
-
Public Improvement Bond – Infrastructure –
The engineering department is responsible for establishing and releasing the public improvement
bond related to public improvements. This includes all of the items listed below:
- Earthwork and erosion control
- Culinary water
- Sanitary sewer
- Storm sewer
- Street improvements
- Secondary water
- Finish items
- Other categories as approved by the city engineer
- Non-public Improvement Bond – This bond is applied to projects where on-site, non-public, landscaping, or common area improvements are required and are included as an addendum to the improvement guarantee. The Engineering Department is responsible for the administration of this bond with cooperation from the Community Development Department, which includes bond preparation, establishment, reductions and releases.
- Public Improvement Bond – Landscaping & Street Lighting – The bond for public landscaping and street lighting is included in the bond agreement as an addendum as the warranty period is different from the typical one year.
- Land Disturbance Activities – Improvement Bond, Revegetation Bond, and Restoration Bond – The engineering department is responsible for the establishing and releasing of bond related to land disturbance, grading, erosion control, revegetation and restoration of areas disturbed as part of development projects.
D. City Attorney Approval of Bond
The city attorney is responsible for the review and approval of the bond agreement.
9.7 Released for Construction Drawings
It is from these documents that the bond estimate sheet and bond are to be prepared. They are a specific set of documents, which are signed by the city and defines the specific public and non- public improvements to be constructed as part of the project. In the case where items are changed during construction, the Developer and his/her engineer/contractor are to submit proposed revised changes, which the City Engineer will then review, approve or deny, and make part of the ‘Released for Construction Drawings’. If the changes are significant enough, the ‘bond estimate sheet’ must also be revised, and a new Public Improvement Bond prepared for these revisions.
9.8 Bond Reductions
Bond proceeds will be reduced on a ‘system-by-system’ basis, and at the most, once monthly. Once all items under a given ‘system’ description have been constructed, inspected and deemed completed by the Engineering Inspector, a written request from the Developer will initiate the processing of the necessary bond reduction. This will result in a 75-percent total reduction in the bond amount for each system prior to the beginning of the Warranty Period, minus the ‘Finish Items’ portion of the bond. Once the Warranty Inspection has been completed, all Corrections List items completed and verified by the Engineering Inspector, the remaining ‘systems’ amounts plus the 90-percent of the ‘Miscellaneous Items’ portion of the bond will be released at this time. At the end of the Warranty Period, the remaining 10-percent of the ‘Public Improvement Bond – Infrastructure’ will be released. The ‘Public Improvement Bond – Landscaping & Street Lighting’ which has a longer warranty period will not be released until its requirements have been met.
9.9 System Inspection Bond Reduction
Bond reductions are on a “system by system” basis to ensure the quality of the end product and speed up the acceptance process. The eight systems are:
- Earthwork and erosion control
- Culinary water
- Sanitary sewer
- Storm sewer
- Street improvements
- Secondary water
- Finish items
- Other categories as approved by the city engineer
A. Developer Written Request for System Inspection and Bond Reduction
City staff will be using the checklists contained in the ‘Private Development Construction Inspection Manual’ for inspection of the project. The Developer is required to have gone through these same checklists, and ensured each of the items is complete, prior to requesting a system release for that particular system. The Developer is to provide the Engineering Department with a written request for a bond reduction and a certification that the ‘system’ work is ready for inspection and reduction. A City form has been prepared for this purpose.
The written request and certification begins the inspection of the completed system and ensures that the developer has completed the work and is ready for an inspection. A written request and certification form are required for each system release. The forms are to be signed and dated. City inspection staff will review the written request and certification and respond in writing to the Developer if the project is not ready for an inspection. If the request and certification are in order, the Engineering Inspector will schedule the project for an inspection.
B. System Inspection and Punch List Preparation
Using the checklists from the Private Development Construction Inspection Manual, engineering inspection staff will inspect the system being requested to be released. If it is determined that the system is not complete and therefore not ready for an inspection, the developer will be notified of such. If the system is worthy of an inspection, then the inspection will be performed and a punch list prepared. The engineering inspector and the engineering inspection supervisor will be involved in the inspection and each person will sign the inspection form.
C. Developer Punch List Corrections
The Developer/Contractor are required to complete all the items indicated on the system/project punch list and then notify the Engineering Department in writing through the use of the proper certification form, that the work is complete. Once the punch list has been prepared and sent to the Developer and Contractor, they are required to complete the items indicated on the punch list. If there are questions regarding any items on the punch list, please contact the engineering inspector for additional information.
The Developer is required to complete all of the items indicated on the punch list. The punch list has a life of 30 calendar days. If items listed on the punch list are not completed within the 30-day time period, the system will need to be reinspected and a new punch list prepared, which will also have a life of 30-days. One inspection is included in the ‘inspection fee’ and therefore, any inspections beyond the first inspection must be paid for by the Developer in addition to the original inspection fee.
Once the Developer/Contractor has completed the City’s inspection punch list, the Developer is to certify in writing that the punch list items have been corrected and a re-inspection is desired. The engineering inspector will re-inspect and certify all items have been completed and then begin the bond reduction process.
D. Bond Reduction Processing
The engineering inspection supervisor will forward his approval to the Engineering clerical staff for bond reduction processing. The Engineering clerical staff will initiate the processing of the paperwork necessary to reduce the bond and obtain the required signatures on the reduction form. System bond reductions will require only the signatures of the Engineering Inspector, Engineering Inspection Supervisor, and the City Engineer for processing.
Once the project reaches the Warranty Inspection, and Final Inspection stage, then other departments will be involved to ensure their concerns are also addressed. The completed reductions forms are forwarded to the city manager for approval of the system release. Once approved by the city manager, the administrative assistant will then copy the documents and distribute them to the Developer.
9.10 Warranty Inspection Bond Reduction
The Warranty Inspection is the time at which the Developer/Contractor and City agree the project is complete, and the Warranty Period can begin. It assumes that an inspection of the entire project will be performed, a punch list prepared and given to the Developer/Contractor, and that the punch list is completed. Once it is agreed that the punch list is completed, then the Warranty Period can begin. In addition to the descriptions contained in this Manual, also please refer to the PDCIM, ‘Section 5.0 – Warranty Inspection/Acceptance Requirements’ for additional details regarding this process. The process is described as follows:
A. Developer Application for Warranty Inspection
City staff will be using the checklists contained in the ‘Private Development Construction Inspection Manual’ for a warranty inspection of the project. The Developer is required to have gone through these same checklists, and ensured each of the items is complete, prior to requesting a warranty inspection and bond reduction. The Developer is to provide the Engineering Department with a written request for a warranty inspection and a certification that the project work is ready for inspection and reduction. A City form has been prepared for this purpose.
The written request and certification begins the inspection of the completed project and ensures that the developer has completed the work and is ready for an inspection. A written request and certification form is required for a warranty release. The forms are to be signed and dated. City inspection staff will review the written request and certification and respond in writing to the Developer if the project is not ready for an inspection. If the request and certification are in order, the Engineering Inspector will schedule the project for a warranty inspection.
B. Project Inspection and Punch List Preparation
Using the checklists from the Private Development Construction Inspection Manual, engineering inspection staff will inspect the project. If it is determined that the system is not complete and therefore not ready for an inspection, the developer will be notified of such. If the project is worthy of an inspection, then the inspection will be performed and a punch list prepared. The engineering inspector and the engineering inspection supervisor will be involved in the inspection and each person will sign the inspection form.
C. Developer Punch List Corrections
The Developer/Contractor are required to complete all of the items indicated on the warranty punch list and then notify the Engineering Department in writing through the use of the proper certification form, that the work is complete. Once the punch list has been prepared and sent to the Developer and Contractor, they are required to complete the items indicated on the punch list. If there are questions regarding any items on the punch list, please contact the engineering inspector for additional information.
The Developer is required to complete all of the items indicated on the punch list. The punch list has a life of 30 calendar days. If items listed on the punch list are not completed within the 30-day time period, the system will need to be reinspected and a new punch list prepared, which will also have a life of 30-days. One inspection is included in the ‘inspection fee’ and therefore, any inspections beyond the first inspection must be paid for by the Developer in addition to the original inspection fee.
Once the Developer/Contractor has completed the City’s inspection punch list, the Developer is to certify in writing that the punch list items have been corrected and a re-inspection is desired. The engineering inspector will re-inspect and certify all items have been completed and then begin the warranty bond reduction process.
D. Warranty Bond Reductions Processing
The engineering inspection supervisor will forward his approval to the Engineering clerical staff for bond reduction processing. The Engineering clerical staff will initiate the processing of the paperwork necessary to put the project into the warranty period and reduce the bond and obtain the required signatures on the reduction form. Warranty bond reductions will require other departments including engineering, planning, and public works.
The completed reductions forms are forwarded to the city manager for approval to begin the warranty period and bond release. Once approved by the city manager, the administrative assistant will then copy the documents and distribute them to the Developer.
E. Public Works Department Notification
Engineering staff notifies Public Works they are responsible for now snow plowing for the project only. All other maintenance activities are still the responsibility of the Developer until the Warranty Period is complete, and the project accepted by the City.
9.11 Final Inspection and Bond Release
A final inspection is to set the time at which the Developer/Contractor and City agree the Warranty Period is complete and the process for a final inspection and bond release can begin.
A. Developer Application for Final Inspection
City staff will be using the checklists contained in the ‘Private Development Construction Inspection Manual’ for a final inspection of the project. The Developer is required to have gone through these same checklists, and ensured each of the items is complete, prior to requesting a final inspection and bond release. The Developer is to provide the Engineering Department with a written request for a final inspection and a certification that the warranty period is over and is ready for inspection and release. A City form has been prepared for this purpose.
The written request and certification begin the inspection of the completed project and ensures that the developer has completed the work and is ready for an inspection. A written request and certification form are required for a final release. The forms are to be signed and dated. City inspection staff will review the written request and certification and respond in writing to the Developer if the project is not ready for an inspection. If the request and certification are in order, the Engineering Inspector will schedule the project for a final inspection.
B. Project Inspection and Punch List Preparation
Using the checklists from the Private Development Construction Inspection Manual, engineering inspection staff will inspect the project. If it is determined that the project is not ready for a final inspection, the developer will be notified of such. If the project is worthy of an inspection, then the inspection will be performed and a punch list prepared. See Flowchart 16-05 Warranty and Final Inspection/Punch List Preparation.
C. Developer Punch List Corrections
Once the punch list has been prepared and sent to the Developer and Contractor, they are required to complete the items indicated on the punch list. If there are questions regarding any items on the punch list, please contact the engineering inspector for additional information. The Developer is required to complete all of the items indicated on the punch list.
The punch list has a life of 30 calendar days. If items listed on the punch list are not completed within the 30-day time period, the system will need to be reinspected and a new punch list prepared, which will also have a life of 30-days. One inspection is included in the ‘inspection fee’ and therefore, any inspections beyond the first inspection must be paid for by the Developer in addition to the original inspection fee.
Once the Developer/Contractor has completed the City’s inspection punch list, the Developer is to certify in writing that the punch list items have been corrected and a re-inspection is desired. The engineering inspector will re-inspect and certify all items have been completed and then begin the final bond release process.
D. Final Bond Release Processing
The engineering inspection supervisor will forward his approval to the Engineering clerical staff for bond release processing. The Engineering clerical staff will initiate the processing of the paperwork necessary for a final acceptance and bond release and obtain the required signatures on the reduction form. Final bond release requires other departments including engineering, planning, and public works.
The completed release forms are forwarded to the city manager for approval to accept the project and final bond release. Once approved by the city manager, the administrative assistant will then copy the documents and distribute them to the Developer.
E. Public Works Department Notification
Once the final inspection and bond release have been approved by the city manager, engineering staff notifies Public Works they are responsible for all operations and maintenance for the project.
9.12 Payment for Extra Inspections
City inspection fee estimates include only one inspection for each type of inspection. The assumption is that the Developer and Contractor have performed their own inspection based upon the City’s inspection forms, that everything is complete, and that it is ready for City inspection. It is not the City’s role to provide ‘quality control/quality assurance’ for the developer’s project, which we feel can be done in one inspection by City staff. Should the inspection require more than one inspection for a ‘system’ bond reduction/release, the Developer will be charged on an hourly rate basis for the City’s additional work effort.
10.0 Acceptance by West Jordan City
The ‘project’ will not be accepted by the City until all of the City’s requirements have been met. Acceptance requirements are fully described in Private Development Construction Inspection Manual
