1 Introduction

1.1 Background

The Town of Golden (Golden) engaged Urban Systems Ltd. (USL) to prepare an Infrastructure

Replacement Priority Plan, intended to assist the Town with long-term capital infrastructure planning that

will see the replacement of infrastructure throughout the community over a 20-year horizon. By

understanding the condition of existing surface and underground utilities, the Town will be able to

proactively move forward with capital projects in an efficient manner.

This report draws on the following previous reports and documents:

• Town of Golden – Council Policy on Corporation-Wide Asset Management, September 2012

• Focus Corporation – 2013 Roads and Infrastructure Assessment, January 2014

• Town of Golden – Identified Asset Renewal Projects Update Memorandum, November 2017

• Urban Systems Ltd. – Road Condition Assessment and Upgrade Plan, January 2018

Golden’s Policy on Asset Management lays the foundation for integrated investment decision-making

across all linear infrastructure types with an emphasis on achieving affordable and cost-effective

strategies that achieve sustainable delivery of services to the community. The Town recently completed

the next step in its asset management program by conducting a Road Condition Assessment and

Upgrade Plan which identified high priority roads for overlay and replacement. Golden is continuing to

move forward with its asset management initiatives to support the objective of being a resilient, financially

sustainable, and healthy community that attracts and retains families, businesses, and industry, and that

also supports local tourism.

The purpose of this report is to review the condition of the underground infrastructure and identify priority

projects to be completed as part of a long-term replacement priority plan. This report provides a prioritized

list of infrastructure projects based on a combined assessment of risk and efficiency to ensure Golden is

strategically spending its funds to reduce risk to the community. Feedback from the Town was

incorporated in the prioritization process to ensure recommendations aligned with the Town’s goals and

values. This plan should be a living document that is reassessed periodically to guide the Town’s capital

planning over the next 20-years.

The major components of this infrastructure replacement priority plan include:

• Review of road condition assessment recommendations

• Age-based condition assessment of sanitary and water infrastructure

• Facility assessment for two wells and three lift stations

• Identification of priority projects with cost estimates

This is done with the goal of creating long term financial plans and annual capital plans and informing

possible future iterations of the Development Cost Charge Bylaw.


1.2 The Town’s Assets

Understanding and managing the community’s infrastructure assets is integral to sustainable service

delivery. Golden contains many infrastructure assets which can be generally categorized into the

categories noted in Table 1.

Table 1: Infrastructure Asset Categories

Linear Assets Non-Linear Assets

Water System Well

Sanitary System Lift Stations

Roadway System Equipment

Storm System Drywells

USL used the Town’s current GIS information to complete an age-based condition assessment of the

underground sanitary and water linear infrastructure. This data was used to assess the remaining

material serviceable life of the water and sanitary system. The 2018 Road Condition Assessment and

Upgrade Plan was also utilized to integrate the road assessment with the utility assessments carried by

this study. USL also reviewed previous video inspections provided by the Town of the sanitary mains for

the projects identified as a high-priority. The Town has also previously completed visual assessments of

the water-main coupons in many areas (where available).

The Town’s storm infrastructure consists of several types of linear and non-linear assets including catch

basins, manholes, drywells, culverts, and piecemeal sections of pipe. The remaining serviceable life of

the storm mains and culverts was assessed using the Town’s available GIS information and recently

collected culvert information.

The Town of Golden identified two priority wells and lift stations to be assessed as part of this work, as it

was not feasible to complete a full inventory and assessment of all non-linear assets. USL reviewed the

previous as-built information and completed a site inspection of these facilities.

2 Asset Management Methodology

2.1 Linear Infrastructure Condition Assessment

To prioritize investments and set sustainable levels of service for linear infrastructure, the Town of Golden

engaged Urban Systems Ltd. (USL) to conduct a condition assessment of its linear infrastructure to aid

in the prioritization of infrastructure projects. The results of the condition assessment are illustrated in the

Appendix A figures.

Road Assessment

Urban Systems undertook a complete inventory of the road network within the Town of Golden in June

2017. The assessment of the road quality was based on a visual analysis of each road. The asphalt and

concrete were inspected for the following deteriorations:

Asphalt:

a. Alligator Cracking b. Block Cracking c. Transverse Cracking d. Longitudinal Cracking e. Rutting f. Raveling g. Potholes h. Settlement i. Edge Deterioration j. Pre-existing Patches

Concrete:

a. Longitudinal Cracking b. Transverse Cracking c. Random Cracking d. Spalling e. Chipping f. Joint Displacement

Once the field condition data was processed and analyzed, a rating was given to each road. The rating

system is summarized below in Table 2.

Table 2: Road Surface Rating Scores

Rating Repair Strategy Score

Very Good Only planned maintenance required 1

Good Minor maintenance required plus planned maintenance 2

Fair Significant maintenance required 3

Poor Significant renewal/rehabilitation required 4

Very Poor Physically unsound and/or beyond rehabilitation 5

Based on the road inventory assessment, every road in the Town of Golden has been ranked based on

the guidelines in Table 2 and assigned a score from 1-5. Appendix A - Figure 1 graphically displays the

results of this assessment.


Underground Infrastructure Assessment

Information on existing watermains, sanitary sewers, storm sewers, and storm culverts was compiled

based on the Town’s existing GIS information. Where gaps in information were present, assumptions

were made based on surrounding infrastructure - this was done in some instances for material type and

age. When the watermain installation date and material was not available but sanitary sewer was, it was

assumed that the watermain installation date and material was the same as the sanitary, and vice versa.

The Town recently collected information on culvert size, location and condition. The culvert data is

incorporated in the storm assessment.

The information was then plotted to display the percentage of serviceable life used, which varies

depending on type of material – see Table 3.

Table 3: Material Serviceable Life

Material Age (years)

Ductile Iron (DI) 50

Asbestos Cement (AC) 60

Cast Iron (CI) 60

Vitrified Clay Tile (VCT) 60

Coated Corrugated Metal Pipe (CMP) 35

Non-coated Corrugated Metal Pipe (NCMP) 80

PVC 80

HDPE 80

ACASS (AC) 60

Copper (COP) 60

Encasement Pipe (ENCASE) 60

Stainless Steel (SS) 60

Concrete Pipe (CONC) 80

Appendix A - Figures 2, 3, and 4 show the percentage of service life consumed for each asset type.

These figures were processed and analyzed using the methodology described in the section below to

generate an Underground Condition Score for each road in Golden.

Combined Infrastructure Assessment

A matrix was created with percent service life consumed data to evaluate the priorities of sanitary

consumed life paired with watermain consumed life as seen in Table 4 below. Storm information was not

used within this evaluation criteria since there were significant gaps in available information. The matrix

is evaluated with the following values:

• 50% service life consumed =1

• 50-75% service life consumed =2

• 75-100% service life consumed =3

75%-100% 9 6 3

75%-100% 50%-75% <50%

The matrix results were then simplified into a normalized score as seen in Table 5 below. This is further

shown in Appendix A Figure 5.

Table 5: Underground Condition Score

(50-75)-(75-100) 4

(75-100)-(50-75) 4

(75-100)-(75-100) 5

The Underground Condition Score and the Road Condition Score were summed together for each road

to get a Combined Priority Score as seen in Table 6 below. The Combined Priority Score assesses the

overall ranking of the underground and road conditions and is seen in Appendix A Figure 6. It was

assumed that the whole road is given a score, even if the pipe infrastructure does not extend the full

length of the road segment.

2.2 Linear Infrastructure Priorities

Based on the previously described assessment criteria, every road in the Town of Golden has been

ranked based on their combined priority scores for the linear infrastructure.

The results in this report are based on combined road and underground infrastructure analysis. Cost

estimate breakdowns per lineal meter of roadway of residential, industrial and collector roads are shown

in Appendix B for silt and gravel subgrade. These cost estimates are provided with more detail on the

selected priority projects.

2.3 Non-Linear Infrastructure Condition Assessment

Well and Lift Station Assessment

Urban Systems inspected two wells and three lift stations identified by the Town of Golden on August 8,

2018. Prior to the site inspection, USL reviewed the available as-built information and operation manuals

and develop a condition evaluation form for the facilities. The following facilities were inspected:

• Edelweiss Sanitary Lift Station

• 7th Street Sanitary Lift Station

• 12th Street Sanitary Lift Station

• Well #2

• Well #3

The goal of the site inspection was to assess the condition and performance of these existing facilities to

develop asset valuation summaries and identify areas of improvement. In general, the well and lift station

facilities appeared to be well maintained. Golden operations staff have been performing ongoing

maintenance and repairs to the buildings, pumps, valves and electrical/monitoring equipment. Detailed

inspection reports can be found in Appendix C.

Video inspection of water wells was not completed, as the entire pump and column pipe assembly needs

to be pulled in order to facilitate camera access. In the case of submersible pumps, their lifespan is only

around 15 years. When the motor fails, it is typically less expensive to remove and replace the

submersible pump, than complete repairs, and there is minimal value in removing them early unless there

is an indicator there is a problem. Vertical turbine pumps, on the other hand, benefit from regular

maintenance. Similar to submersible pumps, however, it is not recommended that these pumps are pulled

to inspect the casing unless there are some indications of a problem as it is an expensive task. Since the

pumps and well could not be inspected visually, condition assessments were not included for them in

Appendix C.

During the inspection of the well and lift stations, there were two primary areas noted as areas of concern

relevant to all facilities. These were:

• System redundancy

• Meeting WorkSafe BC requirements

System redundancy can be used in a variety of situations to improve the safety, reliability, and efficiency

of a system. In the case of an electrical power outage, propane or diesel generators provide a source of

energy to the lift station and well facilities in Golden. The 7 th Street and 12th Street Lift Stations have

permanent gensets on site to provide backup power to these stations as required. The backup generator

for the Edelweiss Lift Station, however, needs to be brought out from the shop to site during power

outages. Backup pumps are also required for these facilities to provide service when repairs are required

or in the case of a pump failure. The inspected wells and lift stations all currently have pumps available

as backup, however, it was noted that there is not consistency of manufacturer or type between pumps.

When pumps are consistent across facilities it allows for ease of part replacement and backup pump

availability. Finally, floats and ultrasonic transducers are frequently used together to provide redundancy


to lift station’s level sensor systems. The Edelweiss lift station currently operates exclusively on floats,

and it is recommended when this station is upgraded, an ultrasonic transducer is included for redundancy.

Another consideration when completing upgrades to the existing lift stations and wells is meeting the

current WorkSafe BC requirements. WorkSafe BC requires that there is a means of pipe isolation, such

as a double block and bleed system, be used in confined spaces (lift stations, PRV stations) for pipes

containing harmful substances. As most of the infrastructure in Golden was installed prior to this

regulation, upgrades, particularly during renovations or replacements, are required to bring these facilities

up to the current standards to ensure worker safety.

2.4 Capital Prioritization Approach

There are a few approaches that can be taken when prioritizing infrastructure projects. One approach is

a purely quantitative exercise that only utilizes condition and capacity ratings to develop a combined

rating for each asset. These results can then be blended with multiple assets in the same vicinity, using

GIS, to attempt to prioritize projects based on social and environmental factors. This approach was not

taken with Golden for four reasons:

• Not all capacity data is available. Recent capacity data for the sanitary system is not available

since there is no current hydraulic model.

• This approach often misses opportunistic projects (ex. A project that could alleviate capacity

or risk without directly replacing the asset in question.)

• It does not consider the Town’s level of service criteria.

• The land use and road type criteria does not necessarily align with the Town’s priority areas.

A holistic approach was taken to prioritize Golden’s infrastructure projects based on the following

framework:

• Condition ratings for each asset type were overlaid to hone in on areas of concern. See Section

2.5 for detail on the methodology processes.

• The condition ratings were coupled with information that was provided by Golden staff. Golden

provided culvert inspection reports and sanitary video inspections which were incorporated into

the assessment.

• Discussions with Golden staff were used to align the approach and methodology with Golden’s

vision for future financial sustainability and strategic priorities. Additional project suggestions were

made based on local knowledge, which were incorporated based on their impact and fit within the

prioritization strategy.


This approach guided the prioritization of capital upgrades based on risk criteria and efficiency.

1) Risk – This is to quantify the impact of the asset’s function either being impeded or interrupted.

This risk assessment is based on likelihood and consequence of failure of the infrastructure.

a. Likelihood of Failure – This is the combination of the overall condition assessments, which

applies a percentage of serviceable life used for each asset based on asset age and the

expected serviceable life of the asset, which is dependent on material. This was coupled

with operator information on field level issues (i.e. break frequency), where available. The

likelihood of condition-based failure is driven by the age of the utility assets and by the

repair needed of the road assets. A utility assets’ age directly relates to the principles of

asset management and tangible capital asset inventories. Road asset conditions are

directly related to the principles of asset management and the necessary repairs to restore

the asset. For this risk assessment, the asset condition based on age was evaluated in

tandem with available asset repair and condition information, from the workshop with the

operations staff, to increase accuracy.

b. Consequence of Failure: The consequence of failure is driven by two key factors: the cost

to restore service and cover third-party liability (potential financial consequence) and the

actual location of the infrastructure (potential traffic disruption consequence and town

priority areas). For example, the consequence of failure to single-family residential

buildings is lower than that of multi-story apartment complexes or industrial, commercial,

or institutional buildings.

2) Efficiency – This is the combination of asset replacements or repairs such that economies of

scale can be used. This dimension can be demonstrated by comparing two possible residential

street improvement projects:

a. The first project’s road surface is in great condition, the sanitary sewer is also in great

condition, but the watermain is very close to the end of its design life.

b. The second project’s road surface is in moderate condition, the sanitary sewer is in

moderate condition, and the watermain is in moderate condition.

In this instance, it is likely more cost effective to proceed with project b. Even though the water

main is nearing its design life it has not posed issues in the past and leaks are infrequent (low

likelihood of failure). Further, because it is a residential street the consequence of failure is

relatively low due to the number of residents affected. So, by proceeding with the project b, Golden

can consolidate the replacement of the sanitary, water, and road to minimize fixed costs

associated with construction.


The following describes the difference between the prioritization categories.

Priority 1: This category is reserved for projects that have both a high consequence of failure as well as a high likelihood of failure. Efficiency is not a defining characteristic of this category but is considered for pricing implications.

Priority 2: This category is typically defined as projects that have a high consequence of failure with a medium likelihood, or high likelihood and medium consequence.

Priority 3: This category is typically defined as projects that have medium-high consequence of failure but a low likelihood of failure. In other words, they are projects that are on the horizon where likelihood is increasing over time.

Another type of project considered for this category are projects where the consequence of failure is low, but the efficiency is high.

2.5 Risk Assessment Methodology

The risk assessment was completed as a multi-infrastructure approach, which focuses on projects that

have immediate and clear community benefit, while being most cost effective. The following project

drivers inform the risk assessment methodology:

• Consider the consequence of not funding a project to ensure adequate but not excessive levels of service could be attained.

• Prioritize asset replacement in projects that achieve the vision and strategic priorities for the community.

• Combine condition and capacity to connect asset management with infrastructure planning and capital planning

The multi-infrastructure risk methodology used incorporates three main components into the project

selection criteria as outlined below:

• An assessment of the infrastructure’s likelihood of failure (i.e., probability) based on condition and capacity.

• An assessment of the infrastructure’s consequence of failure (i.e. environmental, social or economic impacts)

• Risk (i.e., combination of probability and consequence)

The likelihood of failure, consequence of failure, and risk components mentioned above were

utilized for each asset category in the analysis (where information was available)


3 Capital Prioritization List

3.1 Linear Infrastructure Replacement Costs

Complete Surface and Underground Utility Replacement

In general, the cost estimates were completed based on the assumption that the asphalt road and

underground utility infrastructure would be fully removed and replaced. Road widths were approximated

based on previously completed road assessments and available road classification as defined in the

Town of Golden Subdivision and Servicing Bylaw. There will be additional costs if the Town wishes to

upgrade any roads to a different cross section or include additional curb/sidewalk. Detailed cost estimates

assumed no land acquisition, relocation of power poles, landscaping, or streetlights.

For this report, cost estimates have been based on frost susceptible soils being removed and replaced

with clean pit-run gravel for the full depth of the excavation. The recommended type of road and

underground rehabilitation and associated cost estimates should be considered as preliminary and are

intended for budgetary purposes only. Geotechnical investigations and engineering design are

recommended prior to construction to provide detailed rehabilitation requirements, construction

alternatives for silty subgrades and estimated costs.

Alternative Restoration Strategies

Cured-in-place pipe (CIPP) lining is a common method used to restore aging pipe. It has been used for

over 45 years and is a cost-effective way to extend the service life of pipes that may be experiencing

infiltration or leaking due to roots, cracks, or corrosion. Lining is typically less disruptive in comparison to

fully removing and replacing the entire system, as full trenching and excavation is not required.

CIPP lining is a method that uses a liner tube and liquid resin to essentially place a new pipe within the

existing pipe. The liner is infused with a resin mixture and installed in the pipe. The liner is then cured,

and the resin hardens, creating a fitted, smooth, and corrosion resistant new pipe wall. A cutting device

can then be used to reinstate any service connections.

The Town has completed several lining projects since 2010 and has plans to complete additional lining

projects, with the intent to avoid main replacement when the combined road and deep utility project

proceeds in the future. In many situations this renewal methodology can be effective, however the

following additional factors should be considered to confirm this is the appropriate solution for the site-

specific conditions:

• Pipe Condition: Some pipes may be too damaged to line. If there are major cracks or gaps in

the existing main lining is not possible.

• Grade Deficiencies: Lining does not correct any pre-existing grade deficiencies (e.g. sags, offset

joints, bends) in the main as the liner follows alignment of the host pipe. The Town identified

several areas where grease has been building up in the main. These mains should be assessed

on a case-by-case basis to determine if this is due to insufficient slope or structural defects. In

these situations, the pipe should be fully removed and replaced at the correct grade to avoid future


buildup.

• Flow Requirements: Liner installation reduces the internal diameter of the pipe, potentially

reducing pipeline capacity. Current and future flow requirements should be assessed. A liner may

work as a short-term solution. However, if future main upsizing is required, it can be more efficient

to remove and replace the existing main with a larger main that will meet future flow requirements.

• Subgrade Condition: Subgrade materials vary throughout the Town of Golden however based

on previously completed geotechnical investigations it can be typically classified as either silt or

gravel. As discussed in the 2018 Road Condition Assessment and Upgrade Plan, due to the

potential of frost heaving, McIntosh Lalani recommended that frost susceptible soils be removed

and replaced with clean pit-run gravel to a depth of 2.1m, or that insulation be installed prior to

completing surface improvements. Our past upgrade cost comparisons have shown that the

replacement of subgrade soils is a reasonable estimation of the various upgrade options.

Therefore, if excavation and trenching are being conducted to complete the surface replacement

work, there may be time and cost efficiencies to completing full replacement of underground

utilities at this time where road structure replacement to 2.1m depth is contemplated.


3.2 Linear Infrastructure Priority Projects

Based on the criteria described in Section 2 and discussion with the Town of Golden, the following roads

were identified as priority projects and candidates for full road and underground replacement. The below

Table summarizes the total amount of investment that is recommended to be made in linear infrastructure

over the next 20 years.

Table 8: Linear Infrastructure Priority Investment Summary

Total Priority III $5,305,000

Total* $17,470,000

*Average Annual Investment is $873,500 over 20 years

The benefit of the risk assessment is the connection between levels of service, risk, and priorities. As a

result of the methodology and prioritization approach chosen, there is $17,470,000 in priority I-III projects

required in the 20-year horizon, and the average annual amount of investment for these projects over 20

years is $873,500.


3.2.1 Priority I Projects

9th Avenue South/Park Drive – Underground and Surface

Project Description: The scope of this project is to remove and replace existing watermain, some

sanitary sewer and full road width infrastructure. Services are to be replaced to

the property line. The Town of Golden noted that some slip lining work was

completed along Park Drive in 2017.

Project Estimate: $3,147,000– Class C Cost Estimate. Cost estimates have been provided for 9th

Avenue South and Park Drive separately, however these two projects would

likely benefit by economies of scale if completed together. The portion of

sanitary main (135m) that was previously lined was not include in the cost

estimate.

Estimate Limitations: The project estimate includes a 15% engineering and 30% contingency factor.

The geotechnical assumptions utilized in previously completed reports were

maintained in this cost estimate.

Project Priority Dimensions:

Risk

a) Condition These roads were identified as very poor in the previously completed Road

Condition Assessment. 75%-100% percent of the serviceable life has been

consumed for portions of both the watermain and sanitary sewer main, as

shown in Figures 2 and 3 in Appendix A.

Sanitary video inspection reports provided by the Town of Golden identified

multiple sags, fractures, cracks and tree root issues in this area.

b) Consequence Town staff identified this as a priority area, as these roads surround Town Hall

and are in a high-profile area. Since the underground infrastructure is nearing

the end of its serviceable life, the risk of breaks in the sanitary main due to the

identified fractures and cracks is high. If these repairs are not completed

proactively, these roads may need to be shut down for costly emergency repair

work in the future which would cause disturbance to Town staff and residents

in this priority area.

Efficiency These areas were identified as high priority in the both underground and

surface assessments, resulting in a combined ranking of very poor as shown

in Figure 6 of Appendix A. As the underground and surface utilities will require

replacement in the near future, it is most efficient to complete these upgrades

together.

Completing the Park Drive and 9th Avenue South upgrades concurrently would

capitalize on economies of scale, resulting in cost savings.


9th Avenue North – Underground and Surface

Project Description: The scope of this project is to remove and replace existing watermain, sanitary

sewer and full road width infrastructure. Services are to be replaced to the

property line. This estimate also includes the 7th Street North surface upgrades

that will be required at the same time as the 9th Avenue North upgrades are

completed.

Project Estimate: $1,870,000 – Class C Cost Estimate.

Estimate Limitations: The project estimate includes a 20% engineering, contract administration,

survey and geotechnical testing and 10% contingency factor. The geotechnical

assumptions utilized in previously completed reports were maintained in this

cost estimate.


Risk

c) Condition The road in this area was found to be in very poor condition in the previously

completed Road Condition Assessment.75%-100% of the serviceable life of

the watermain and sanitary main has been consumed throughout the entire

road. Town staff confirmed the age base condition assessment and identified

this project as a priority.

d) Consequence The Town identified this project as a priority because the current surface

condition is very poor. This road is located in Golden’s main downtown area,

and as such, it is important that the surface be improved.

Since the underground infrastructure is nearing the end of its serviceable life,

the risk of breaks in mains are high. If the underground infrastructure is not

completed proactively with the improvement of the surface infrastructure, these

roads may need to be shut down for costly emergency repair work in the future

which would cause disturbance to businesses in this priority area.

Efficiency This area was identified as high priority in the underground and surface

assessments and by the Town. As both the underground and surface utilities

will require replacement in the near future, it is most efficient to complete these

upgrades together.

Completing the 9th Avenue and 7th Street upgrades concurrently would

capitalize on economies of scale, resulting in cost savings.


3.2.2 Priority II Projects

14th Street South – Underground and Surface Improvement


sewer and full road width infrastructure. Services are to be replaced to property

line.






Risk

a) Condition The road in this area was found to be in poor/very poor condition in the

previously completed Road Condition Assessment. The sanitary infrastructure

between 7th Ave S and 9th Ave S has consumed 75%-100% of its serviceable

life and the segment between 9th Ave S and 11th Ave S was found to be less

than 50% consumed. 75%-100% of the serviceable life of the watermain has

been consumed throughout the entire road.

Town staff confirmed the age base condition assessment and identified this

project as a priority. Town operations staff have observed the condition of the

sanitary sewer deteriorate significantly in recent years. They have identified

issues with pipes sagging and roots.

b) Consequence If the main is not replaced, oil and grease will continue to buildup in the main

and require frequent maintenance.

Efficiency This area was identified as high priority in the underground and surface

assessments and by the Town. As both the underground and surface utilities

will require replacement in the near future, it is most efficient to complete these

upgrades together.


10th Street South (A) – Underground and Surface Improvement


sewer and full road width infrastructure from 7th Ave. to 11th Ave. Services will

be replaced to property line.

Project Estimate: $4,058,000 – Class C Cost Estimate





Risk

a) Condition This road was identified as very poor in the previously completed Road


consumed for both the watermain and sanitary sewer main, as shown in

Figures 2 and 3 in Appendix A.

b) Consequence The Town identified this project as a priority because the current surface

condition is very poor. Since the underground infrastructure is nearing the end

of its serviceable life, the risk of breaks in mains are high. If the underground

infrastructure is not completed proactively with the improvement of the surface

infrastructure, these roads may need to be shut down for costly emergency

repair work in the future which would cause disturbance to residents in this

priority area.

Efficiency The Town identified this road as a high priority. As both the underground and

surface utilities will require replacement in the near future, it is most efficient to

complete these upgrades together.


3.2.3 Priority III Projects

10th Street South (B) – Underground and Surface Improvement


sanitary sewer and full road width infrastructure from 14th Ave. to the West end.

Services will be replaced to property line. The Town of Golden noted that some

sanitary slip lining work was completed in 2018.

Project Estimate: $1,540,000 – Class C Cost Estimate



maintained in this cost estimate. The portion of sanitary main (120m) that was

previously lined was not include in the cost estimate.


Risk

c) Condition This road was identified as very poor in the previously completed Road




Sanitary inspection videos provided by the Town of Golden identified multiple sags, fractures, cracks and tree root issues in this main.

d) Consequence Operations has identified this project as a priority because the current surface

condition is very poor. Similar to 10th Street South (A), the underground

infrastructure is nearing the end of its serviceable life and the risk of breaks in

main is high due to the sanitary video inspection results mentioned above.

Proactive repairs will alleviate the need to shut down the road for emergency

repair in the future, which can be costly and disruptive to adjacent residences.

Efficiency The Town identified this road as a high priority. As both the underground and

surface utilities will require replacement in the near future, it is most efficient to

complete these upgrades together.


8th Street South – Underground and Surface Improvement

2017.




maintained in this cost estimate. The portion of sanitary main (280m) that was

previously lined was not include in the cost estimate.


Risk

a) Condition This road was identified as very poor in the previously completed Road




Sanitary inspection videos provided by the Town of Golden identified multiple

cracks and holes in the pipe.

b) Consequence Operations has identified this improvement project as a high priority as there is

heavy roadway centerline cracking. Historically, there have also been many

water service line issues in the area due to corrosive soils.

Town staff water service repairs completed in the area over the last decade are

due to the corrosive soils and related to original construction issues. This is

disruptive to the residence in the area and costly to the Town. Underground

and surface improvements for this priority project will decrease the time and

maintenance costs that the Town is currently spending in this area by renewing

the serviceable life of the infrastructure.

Efficiency As both the underground and surface utilities will require replacement in the

near future, it is most efficient to complete these upgrades together. Addressing

the service line issues will decrease maintenance costs.


TCH East Service Road – Surface Improvement

Project Description: The scope of this project is to remove and replace the existing full road width

infrastructure including earthworks and concrete works.






Risk

c) Condition This road was identified as very poor in the previously completed Road

Condition Assessment. The sanitary and water infrastructure were found to be

in good condition as shown in the Combined Underground Ranking figure in

Appendix A. The Road Condition Assessment has identified the condition of

the roadway to be in very poor shape.

Sanitary inspection videos provided by the Town of Golden identified multiple

cracks in the pipe.

d) Consequence The Town of Golden has identified this project as a high consequence priority

since many people travel on the service road while passing through the town

and is subject to frequent heavy truck traffic. The current condition of the road

is degraded due to age and frequent heavy traffic loading as well as existing

drainage limitations. The surface condition will continue to deteriorate if not

addressed and may cause further damage to underlying infrastructure in the

future.

The sanitary issues identified above can be addressed using a liner in areas of

need to reduce maintenance effort and costs in the future.

Efficiency This project is standalone and does not have efficiency with respect to

economies of scale. However, a surface overlay would increase the life and

durability of the road, decrease maintenance costs, improve the drivability, and

improve the level of service being provided, but would not address current

limitations associated with existing drainage infrastructure.


3.3 Non-Linear Infrastructure Priority Projects

For the purpose of this report, cost estimates have been completed on an individual project basis,

based on previously completed work in similar areas, for projects identified as priorities for repair,

replacement, or upgrades.

Based on the information above and discussions with the Town of Golden, the following non-linear

infrastructure projects were identified as priorities for repairs, upgrades, and replacement.

PRV Station - Pine Drive


3.3.1 Priority I Projects

11th Avenue/12th Street Manhole Repair

Project Description: The scope of this project includes plugging the south outlet of the sanitary

manhole at the 11th Ave and 12th Street intersection to address the grease

issues being experienced in the 10th Avenue sanitary main.

Project Estimate: $5,000 – Operational Cost Estimate

Estimate Limitations: The estimate is based on high-level maintenance costs for similar work. If

grease buildup persists, additional assessment and repairs may be required to

resolve it.


Risk

c) Condition Operations staff identified this as a high priority improvement project. The Town

has been experiencing significant grease buildup in the 10 th Avenue sanitary

mains. The sanitary flows collected through this main are primarily residential

and should not contain the levels of grease and oil that are being encountered.

It appears as though the sanitary flow from 14th Avenue (which contains high

levels of grease and oil) is entering the manhole at 11th Avenue and 12th Street,

being skimmed off at the surface, and collecting in the 10th Avenue mains.

The surface for 10th Avenue South is currently in good condition. It should be

noted that this road asset belongs to the MoTI. The watermain and sanitary

sewer Figures 2 and 3 are shown as 75%-100% percent serviceable life

consumed in Appendix A.

d) Consequence The grease buildup in the 10th Avenue main currently needs to be cleaned

several times a year which results in additional cost to the Town and requires

more operations time to complete the maintenance.

The affected sanitary main conveys high flows, making any failures in this main

highly consequential. 10th Avenue is an arterial/highway, and any major

underground failures as a result of the grease buildup would be costly to repair.

By addressing the issues at the identified manhole, the Town may be able to

avoid further costly maintenance and repair work.


economies of scale. However, taking proactive measures to address the

underground issues for the system will decrease maintenance costs to the

underground infrastructure in the future.


Edelweiss Lift Station Replacement

Project Description: The installation of a new prefabricated lift station (including permanent

stationing of mobile diesel generator for backup generator and ultrasonic

sensors) is required as the existing lift station is nearing the end of its

serviceable life.

Project Estimate: $642,000 – Class C Cost Estimate


The estimate assumes a basic prefabricated station with no above grade

building. Costs have been included to install fencing around the perimeter of

the site and to meet new WorkSafe BC requirements.


Risk

a) Condition The current lift station does not meet WorkSafe BC requirements and will need to be upgraded to achieve these standards when replacement occurs.

Pipe supports and valves within the existing lift station are corroded. Infiltration is experienced at manhole barrel connections within the wet well, especially during seasons of high groundwater. Furthermore, the operators noted that storage capacity of the existing wet well is inadequate.

The existing lift station does not have permanent measures in place to provide redundancy in the case of power failure or float error. See Appendix C for the Well and Lift Station Evaluation Form.

b) Consequence Infiltration contributes to higher flows within the lift station and decreases the

available storage capacity of the wet well. A prefabricated fiberglass wet well

will eliminate groundwater infiltration potential, reducing in-flows and

associated pumping costs. If adequate storage volume is not provided, the

pumps will run continuously, requiring more maintenance and decreasing

their service life, both resulting in additional costs to the Town. The upsize

would alleviate capacity issues and allow for additional development related

upstream sanitary flows.

As the existing lift station currently operates only on floats there is no backup

measure in place to ensure the station continues operating as designed.

Without a measure of redundancy such as ultrasonic sensors, the lift station

and pumps are at a high risk of failure (pumps running continuously,

overheating due to low water levels, lift station overflow, etc.).

A backup generator must be brought to site when backup power is required,

which takes time and additional man-hours, posing a risk to the operation of

the station during these events.



economies of scale. However, once upgraded, maintenance costs should

decrease.

3.3.2 Priority II and III Projects

7th Street Lift Station Upgrades

Project Description: Upgrades to the 7th Street Lift Station are proposed to mitigate odours from the

station. Mixed-use commercial and residential development is planned for this

area, and upgrades to the station will be required for year-round odour control.

This facility upgrade should be contemplated before adjacent land development

occurs. The Town of Golden also identified that the installation of permanent

station influent metering should be completed at the time of the odour control

upgrade work.

Project Estimate: $585,000 – Class D Cost Estimate

Estimate Limitations: The project estimate includes a 50% engineering and contingency factor. It is

assumed that the odour control upgrades to this lift station will be similar to the

upgrades recently completed at the 12th Street Lift Station. Detailed

comprehensive assessment and design will be required to determine the best

solution for this station. This estimate only includes the capital costs for the

odour control; it does not include additional electrical upgrades. Operation and

maintenance costs are variable depending on the odour control technology

implemented.


Risk

e) Condition This dimension did not have influence over this project’s prioritization as the existing lift station does not contain odour control equipment. See Appendix C for the Well and Lift Station Evaluation Form.

f) Consequence The Town expressed concerns with odour control for this lift station. The current

impact of odours is minimal as there is no adjacent development. However, as

development is planned in the surrounding area, proactive measures should be

taken to ensure odours are mitigated at this time.


economies of scale. However, there could be efficiencies by combining this

work with other upgrades to the lift station. Upgrades to the station will also

likely be required to meet the current WorkSafe BC standards.


PRV Station Upgrades

Project Description: The scope of this project is to bring the existing PRV stations above ground to

allow for ease of ongoing PRV maintenance and avoid WorkSafe BC standards

for confined spaces. The following PRV stations were identified by the Town

operators as priorities:

• Existing Golden Donald Upper Road PRV

• Proposed Selkirk Drive PRV

• Existing Granite Drive PRV

• Existing Pine Drive PRV

Project Estimate: $490,000 per PRV Station – Class C Cost Estimate

Note: Estimated $15,000 savings for proposed Selkirk Drive PRV, as removals

and decommissioning not required.

Estimate Limitations: Detailed engineering design is required to determine the required PRV sizes

and site-specific requirements for each of the new PRV stations. This cost

estimate is based on similar projects completed in the area.


Risk

a) Condition The existing PRV stations do not meet WorkSafe BC regulations and are

difficult to maintain as constructed.

b) Consequence There are safety risks to the system operators as the existing PRV stations are

underground and do not meet the current safety requirements.

If any of these PRV stations require repair, additional time and cost will be

required to complete the necessary work and upgrade the station to meet the

WorkSafe BC regulations. If a shutdown is required to complete the repairs,

there will be an interruption to residents in the service area.

Efficiency The costs for this work were estimated on an individual PRV station basis.

There may be efficiencies with respect to economies of scale if multiple PRV

station projects are completed together. Prefabricated stations are also a

possible option for overall project efficiency and cost savings.

5 Funding and Implementation Strategy Recommendations

To ensure sustainable delivery of services, it is the responsibility of Council and management to ensure

Golden is financially sustainable for current and future generations. A funding strategy within an

infrastructure replacement priority plan would typically identify the sources and assess the adequacy of

revenues for the selected list of capital projects. The infrastructure identified in this plan were prioritized

based on their level of risk and efficiencies in Priority I, Priority II and Priority III assets to provide a

reasonable level of service for customers.

A key outcome of this study is the need for Golden to assess the current investment levels against

infrastructure upgrades proposed from the prioritization by developing a funding strategy using the asset

management framework (such as the Financial Management Framework, Capital Priority Framework,

Asset Management Plan and/or Asset Management Implementation Plan). The aim of the funding

strategy would be to organize the costs and expenditures over 20 years and then to identify the sources

of revenue to fund projects. The refinement of timing, phasing and affordability of projects will be

completed as part of Golden financial planning and integrated capital planning process.

5.1 Implementation Plan and Recommendations

The funding strategy and implementation plan for the infrastructure prioritization includes the following

recommendations:

• Develop a long term financial and capital plan to ensure sustainable service delivery, which

will provide further direction in determining the affordable annual investment in infrastructure.

Funding will be allocated based on priority, with a schedule that is consistent with the future

financial plan requirements and policy.

• Determine funding requirements to address potential municipal contribution gap:

o Work toward a solution that is not reliant on grants

o Consider ability to pay before implementing changes

o Explore alternate revenue and cost recovery strategies

o Ensure revenue is sufficient to sustain desired levels of service

• Phase in capital projects based on asset priority and their risk trigger; i.e., condition and

consequence.

• Develop budgets for Priority I infrastructure asset renewal projects (as listed in the above Table

4) in the 5-year Capital and Financial Plans. Priority I projects should be selected over Priority II

projects.

• Review of water and sewer fees and rates (self-funded utilities).

• Update the Sanitary Sewer Master Plan to address the lack of data of sanitary sewer system capacity under existing conditions and for future developments.
