MS4 Audit: Resolve to be organized and ready in 2018

Happy New Year!

Most people use this time of year to get organized, so that they can put their best foot forward over the next 12 months. Ads for your local hardware store are jam-packed with sales on storage bins and closet organizers.

But the need to be organized extends beyond the home into the office, too. With MS4 permit requirements on the rise, many municipalities have seen their program grow in complexity over the past 5-10 years. With that added complexity comes a lot of paperwork: mapping, inspection and maintenance reports, etc.

PA DEP and the EPA both conduct periodic audits of MS4 programs, and the first step of the audit is to review the municipality’s records. So it’s a good idea to make sure your files are complete and well-organized now – in case 2018 is the year an auditor knocks on your door.

Most audits occur at random.

DEP uses the audit process as a way of educating local municipalities about what the MS4 program requires and answering municipalities’ questions about compliance. It is not meant to be an adversarial experience; it’s an opportunity to see whether your program is working and what you can do – if anything – to improve it.  Because it is mostly an educational outreach, fines are rare at this time, but, in the coming years, audits will focus more on program results, and fines will be more likely.  That’s why it’s important to get your MS4 program audit-ready now.

MS4 audit

What documentation do you need to have for an MS4 audit?

DEP provides an Inspection Report, which lists the documentation inspectors typically will ask to see. However, the inspector can ask to see other documentation not specifically listed in the Inspection Report.

Is your stormwater mapping complete and MS4 audit ready?

In addition to the actual permit and program document, you should keep all monitoring data and reports for at least one year after the permit expires. You should also keep meeting minutes, inspection schedules and records, as well as documentation of illicit discharges and the methods used to resolve them.

You should have a thorough inventory (with mapping) of the location and function of all your stormwater facilities and any municipal facilities that impact your stormwater program. This includes:

  • All of your outfalls with an outline of their drainage area.
  • Inlets
  • All of your post-construction BMPs (even those that are privately maintained. The MS4 is ultimately responsible for ensuring these facilities are maintained properly, even if private owners have agreed to perform that maintenance. Make sure you have a copy of the maintenance agreement you made with the private owner.)
  • Maintenance and storage yards
  • Composting sites
  • Wastewater treatment facilities
  • Streets and parking lots

Furthermore, you should assemble your policies and completion records for street sweeping and snow removal, lawn care and vehicle fueling and washing.

DEP says that poor or unavailable mapping is one of the main problems encountered in an MS4 audit. Even if you haven’t received notification of an impending audit, it’s a good idea to speak with your engineer about whether your existing mapping is adequate. By the time an audit notification arrives, it will probably be too late to update the mapping then.

 

DEP has gone on record saying that it hopes to audit each MS4 program once during its five-year permit term, so it isn’t a question of “if” you will be audited but “when.”

The list of records an auditor can request is extensive, so it is not the kind of information you can pull together quickly (particularly if your mapping needs updated). You ought to make sure your records are in order now.

In addition, your staff should be knowledgeable of the program and able to answer questions about it effectively. Your engineer can provide training to prepare your staff for MS4 audits, if desired.

With a little advance preparation, you can be sure you’re ready when DEP comes knocking on your door.

Stormwater management costs are on the rise.
MS4 requirements continue to become more stringent.
Aging infrastructure is nearing its useful life and will need replacement.
Can your community afford to address these issues?

 Yes, and this webinar can help.

In it, we provide real-world examples of how municipalities are working together to reduce the cost of regulatory compliance and infrastructure O&M. We also provide guidance on how to successfully negotiate intergovernmental agreements that protect everyone’s interests.

Adrienne M. VicariThe presenter, Adrienne Vicari, is our Financial Services Practice Area Leader. Her regional approach to stormwater management is projected to save municipalities in the Wyoming Valley more than $200 million over the course of 20 years. PA DEP Secretary Patrick McDonnell praised the initiative, saying “By working together, these municipalities are reducing pollution less expensively than they could if they were making these efforts separately. I am certain that the rest of the state will be looking at their exemplary leadership.”

WEBINAR: Manage Your Infrastructure Easily and Cost-Effectively

Do you know the location of your infrastructure assets?

Do you know what needs inspected and when?

Do you know which assets are most critical and carry the highest risk to the community if they fail?

 

The answers to these questions are crucial to protecting the safety of people and property in your community.

You’re responsible for miles of infrastructure, and your job is to make sure it continues to function for the people you serve. Whether it be pipes and inlets, roadways, or bridges, you have to keep them performing at an acceptable level of service, and, more importantly, you must protect local residents and business from the consequences of failure.

This has always been a complex job, but new regulatory requirements, aging infrastructure, and tight municipal budgets make it even harder.

An asset management program can make it easier and more cost-effective, and this webinar will show you how.

Asset management is a proven methodology for determining where to best allocate your infrastructure dollars. It helps you cut through the questions and prioritize exactly what needs repaired or replaced. It can also help you effectively plan and mobilize the money to address those needs.

In this webinar, we’ll discuss:

  • What asset management is and how it works
  • What types of technology is available to assist with asset management and how to determine your particular needs
  • The many benefits of asset management for better targeting O&M dollars; providing justification for rates, fees or budget allocations; addressing government reporting requirements; and communicating with the public.

Flood Control Article Advice from Erin Letavic in Borough News

Erin Letavic, a project manager in HRG’s civil group, published an article in the July issue of Borough News magazine about flood control entitled “Mitigating Flood Risk in Your Borough.”  In it, she discusses the costs municipalities face when flooding occurs and offers  tips for how to minimize the risk of flood damage as much as possible.

Topics she discusses in the article include

  • Understanding your community’s flood risk
  • Improving floodplain management in your community
  • Expanding vegetation that absorbs flood waters and filters pollutants
  • Promoting the construction of green infrastructure
  • Obtaining funding for flood mitigation measures
  • Gaining public support for flood mitigation measures

Flood control strategies can help communities manage their flood risk and lower the potential cost of flood damage

Severe floods can happen in any community, and, when they do, they can wreak serious havoc: destroying homes and businesses, threatening people’s safety, temporarily shutting down the economy, and damaging infrastructure.

Communities can manage flood risk by implementing a flood mitigation strategy. The first step in flood control is to determine what areas of your community are most vulnerable to flooding and model exactly how those areas would be impacted by particular flood events. The next step is to make sure your ordinances and codes limit development in flood-prone areas and promote the planting and preservation of vegetation that will absorb flood waters and reduce flood intensity.

Successful flood control plans require cooperation among all stakeholders in a community, so it is essential to involve them throughout the planning and implementation stages. Obtaining grants and loans to support the initiative will help reduce opposition and lessen the impact on tight municipal budgets.

While the risk of flood damage cannot be completely eliminated, municipalities can greatly enhance the safety of their communities with a forward-thinking approach. The planning a municipality does today is key to weathering the storms tomorrow may bring.

How to Choose the Best Method of GIS Data Collection for Water and Sewer Systems

Infrastructure Asset Management: Business Principles to Maximize Government Revenue Returns

This post is an excerpt from an article we published in the June 2017 issue of Borough News magazine entitled “Strategic Asset Management: Optimizing Your Borough’s Dollars.”

We hear a lot these days about the virtues of running government like a business, but what does that mean?

Any profitable business owner can tell you that success doesn’t happen by accident. Managers spend a good bit of time and money studying the environment in which they operate, identifying opportunities and threats, and planning the best ways to maximize growth while minimizing risk.

Though these efforts cost money, prudent managers know it is an investment in the company that will pay higher dividends over the long-term.

Part of a businessman’s overall strategic planning effort involves cataloguing his assets and maximizing their value. Assets can be wide-ranging: from people to trucks to buildings. The goal of asset management is to optimize the way you spend your budget dollars in order to make sure they are providing the biggest return: reducing the life cycle costs while maximizing the service each asset provides.

Who needs to optimize the way they spend their budget dollars more than cash-strapped municipalities under pressure to keep taxes low while obligations increase?

Most municipalities are grappling with aging infrastructure. Take water systems, for example: The American Society of Civil Engineers estimates that the cost to keep our water and wastewater system functioning over the long term is more than $1 trillion. While there is plenty of work to be done, there is simply not enough funding for communities to do it all at once. Therefore, ASCE recommends assessing the condition of every pipe and valve to determine the risks of failure and properly allocate funds where they are needed most. Asset management and capital improvement planning can help you target your limited budget dollars most effectively in all types of infrastructure: roadways, bridges, stormwater management systems and more.

For example, new technology is making it possible for municipalities to extend the life of their roadways through roadway management systems. Cameras and laser-scanning technology can be mounted to trucks that record the conditions of a municipality’s entire roadway system: noting cracks, pot holes, wheel rutting, and more. Doing this work manually would’ve been too labor-intensive and cost-prohibitive for communities in the past, but now, thanks to technological advancements, municipalities can collect better data at a lower cost without road closures or detours!

Once the data is collected, the municipality can work with an engineer to analyze it and prioritize a list of maintenance, repairs and reconstruction needs. A roadway management program like this emphasizes cost-effective, preventative maintenance activities to prolong the life of a roadway in good condition. By making well-timed, proactive investments, the municipality can enjoy better service from the roadway at a lower lifetime cost.

Silver Spring Township Roadway Management Program

HRG has designed a roadway management program for Silver Spring Township that is helping them save money and better position themselves for grant funding. Learn more

The same asset management and capital improvement principles can be applied to bridges, as well. Typically, this is done at the county level since they own more bridges than municipalities, but the process is similar. When Dauphin County first embarked on its bridge management program, 1/3 of its bridges were structurally deficient. They carefully catalogued the condition of each bridge and prioritized repairs and replacement contracts. Today, they have successfully eliminated all load-posted, structurally-deficient bridges in the county. The program has been so successful it’s generated a surplus of liquid fuels funding, and the county has been able to funnel that into a subsidized loan program for its municipalities to address their own infrastructure needs.

Thanks to careful planning and a wise use of funds, Dauphin County recently completed the replacement of its last load-posted, structurally deficient bridge. Now they can use their Liquid Fuels money for an innovative infrastructure bank that is helping municipalities and the private sector improve local communities. Learn more

Asset management programs can be very important to municipalities looking to meet their MS4 stormwater obligations, as well – particularly if they are considering the implementation of a stormwater fee. Aging infrastructure and growing MS4 permit obligations are compelling municipalities to upgrade their stormwater systems. Though legislation allows them to charge a stormwater fee, they must be able to justify it, which means they must conduct a thorough inventory of their facilities and document the work that must be done to keep it functioning (along with cost estimates for that work). These are crucial facets of an asset management system.

Mobile GIS Development for MS4 Inspections

Municipalities will need a thorough inventory of their stormwater facilities and their condition in order to keep up with the increasing burden of MS4 permitting. Learn about a GIS application HRG created for Hampden Township to help them meet MS4 inspection and reporting requirements.

 

What is asset management?

Asset management is a systematic approach to minimizing the cost of owning, operating, and maintaining your infrastructure at acceptable levels of service.

It is not a computer system or GIS, though these are often valuable tools employed in an asset management program for record-keeping and data analysis.

A proper asset management and capital improvement program will help a municipality identify areas where money is not being spent wisely and reallocate those funds where they can be most beneficial.

It will also help you recognize and evaluate options for keeping your assets functioning for a longer period of time, so that you don’t need to invest in expensive upgrades or replacements as frequently.

It is a circular process that never ends.

Circular Nature of Asset Management

Many things change over time: the condition of your assets, regulations and the business climate you operate in, the number of users you serve, etc.  A good asset management and capital improvement program helps you plan for these changes in advance and respond proactively before they become threats to your bottom line.

 

What are the benefits of infrastructure asset management?

As we’ve already stated, an asset management and capital improvement program helps you identify exactly what maintenance and repair work is necessary without guesswork. This approach has multiple benefits:

Minimizing Risk
Knowing which infrastructure is most likely to fail (and correcting deficiencies before it does) can save you major expenses later. Knowing which failures would be the most catastrophic helps you target money toward their prevention as a first priority.

Maximizing Returns
Asset management and capital improvement planning is all about proactively investing in measures to extend the life of your infrastructure.  These small investments can extend the life of an asset by several years.

Optimizing Service and Satisfaction
Proactively maintaining your assets ensures they function at peak performance for a longer period of time and are replaced before they fail. This means your constituents receive top quality service without disruption and are happier for it. In addition, many asset management solutions include optional customer service applications that make it easier for residents and business owners to submit service requests and track them to completion.

Justifying Your Tax Rates or Fees
Rate increases are never popular, but they are easier for people to accept when they are backed up with clear data showing exactly what improvements are needed and why.

Accessing grants and loans
Competition for funding is fierce, and government agencies are under pressure to make sure the money they invest is used wisely. As a result, they’re more likely to award funds to municipalities who have clear documentation of the project need, its benefits, and a plan for getting it built, operating it, and maintaining it at optimum levels over time.

Improving your worth
Many municipalities have been considering the option of leasing or selling their assets as a response to growing financial obligations in the public sector. A comprehensive asset management system provides documentation of the value of your assets, so you can ensure you are in a position to negotiate the best possible deal for you and your constituents.  Potential investors will be more comfortable making a significant investment if they fully understand the value and the risks they’re assuming.

But asset management can benefit your financial picture even if leasing or selling is not on the horizon.

Under GASB standards, governments can either subtract a standard portion of their infrastructure’s value each year to account for depreciation (the traditional approach), or they can regularly assess the condition of the infrastructure, invest in maintenance to keep it in good condition, and then report the amount of money they have invested in maintenance (the modified approach, which is similar in scope to a typical asset management program).  Using the modified approach, the assets don’t have to depreciate in value like they would in the traditional approach.

A recent article in Governing magazine showed how investors appear to prefer trading bonds from governments that use the modified approach:

“Governments that use the modified method trade at much narrower price ranges compared to bonds from governments that depreciate. In other words, when a government uses the modified approach, investors are much more likely to agree on how to price its bonds. For governments, this can ultimately translate into lower bond interest rates.”

(excerpted from “Selling Your Sewer’s Story – Financial statements can make the best case for public works investors”)

 

The truth is, you’re going to have to invest in maintenance and repair anyway. If you invest in an asset management program, you can take a proactive approach to determining what maintenance is needed and then plan and budget for it in advance. This means you can target your maintenance dollars where they’re needed most and make sure you have the funds available to do the work before infrastructure failure brings even greater costs to bear on your budget.

Publicly-traded companies are held accountable to their shareholders. They must demonstrate that they are making good decisions for the future health of the company and maximizing the value of the shareholders’ investments. Taxpayers are coming to demand the same sort of accountability from their government, wanting proof that their tax dollars are providing a good return, as well. Municipal managers that can prove the value of their decisions will enjoy broad support of their constituents while improving the long-term financial stability of their community.

Carlisle Borough Uses Infiltration/Inflow Data to Devise Long-Term Plan for Infrastructure Repair and Replacement

Like many municipalities, Carlisle Borough is grappling with the challenge of aging infrastructure. Its sewer system features infrastructure that is more than 100 years old.  Since replacing it all at once is not possible from a financial perspective, borough officials needed to a way to narrow down exactly where investment should occur.  Which projects would provide the most value to Carlisle residents and business owners?  Infiltration and inflow data provided the answer.

Why infiltration and inflow data?

In the words of Carlisle Borough staff, “Inflow and infiltration is really just a symptom of failing infrastructure.” By figuring out where extraneous flow is entering the system, we get a hint as to where cracks or defects in the infrastructure may be located.

Josh Fox recently authored an article in the April/May/June issue of Keystone Water Quality Manager magazine on this project with the borough’s director of public works Mark Malarich, P.E.

The article discusses how HRG’s engineers evaluated infiltration and inflow data to determine what infrastructure needed repairs or replacement the most. First, the borough implemented a 16-week metering program to identify dry weather flow for comparison to wet weather data for the borough’s 21 sewer basins.

We then used the data to calculate peaking factor and total infiltration volume for each of the basins and ranked the basins accordingly. After analyzing the data, we determined that some basins had high peaking factors but infiltration dropped off quickly once the wet weather dissipated (like Area 1C in the figure below).  Other basins saw high infiltration volumes for several days after a wet weather event (like area 4 in the figure below).  This suggested that a high groundwater table was contributing a sustained flow via defects in the manholes, sewer mains and sewer laterals.  Therefore, total infiltration volume provided the best data for assessing the overall condition of the infrastructure.

 

Infiltration-Inflow-Data-from-Two-Basins

Taking our analysis one step further, we prioritized the basins with the highest total infiltration volume for further investigation and compared the total volume of infiltration/inflow in a basin to its size. By calculating the total infiltration per foot of pipe, we were able to more accurately estimate the severity of damage in each basin.  (For instance, two basins may have had similarly high total infiltration volumes, but one was significantly smaller than the other.  This suggests a higher severity of defects in the smaller basin for that much water to infiltrate in a smaller space, during the same time period, after the same wet weather event.)

Prioritized Basins by each factor

Using this data as a guide, HRG worked with the borough to devise a 20-year capital improvement plan for addressing the highest priority needs in the system.  HRG also helped the borough create a financial strategy for addressing these needs.

Rehabilitation of the highest priority basin is being completed in the spring of 2017 and is expected to come in almost $1 million under budget.

Adaptive Traffic Signals Reduce Delay, Increase Safety, and Improve Public Satisfaction

Could adaptive traffic signals improve traffic flow in your municipality? Read on to learn:
• The benefits of adaptive traffic signals.
• How they work (and what technology/equipment is required).
• How much adaptive traffic signals cost.
• Where you can obtain funding for implementing adaptive traffic signals.

As traffic engineers, friends have asked us for years if we could give them a magic button to turn traffic signals green whenever they approach the intersection. We smile and chuckle at the joke, but the truth is: The technology already exists for traffic signals to sense cars approaching the intersection and adjust their phasing in response.  It’s called adaptive traffic signal control, and you may already have encountered it in your travels without knowing it.

advanced traffic signal with mounted camera

Cameras mounted on the mast arm detect oncoming traffic and send this information to a central computer.

 

What are adaptive traffic signals?

In the simplest sense, adaptive traffic signals adjust the timing of their green light cycles to match current traffic conditions on the ground. They are constantly collecting data about approaching vehicles and creating new timing sequences to match them.

It’s this second part that distinguishes them from the responsive signal systems many municipalities have today.  While a responsive system will adjust timings based on current traffic conditions, it can only respond with one of its preset cycle programs – trying to find the closest match it can.  An adaptive system creates a completely new timing sequence that is customized to current conditions.

It’s a very efficient way to move traffic through a busy corridor.

How do they work?

  • Video cameras and sensors collect information about the vehicles approaching an intersection.
  • Software analyzes this information and creates a customized timing sequence in real time.
  • The software communicates this sequence to coordinated signals up and down the corridor, so that they all function in sync with each other.

What are the advantages of adaptive traffic signals?

They move traffic along faster and with fewer stops. Signals are constantly being reprogrammed to maximize the green light length and allow the most cars through.  Multiple intersections are coordinated, so that traffic can move freely throughout the corridor, rather than encountering frequent starts and stops.

(It’s important to note, however, that adaptive signals cannot create more time or capacity. They simply allocate time in a more efficient manner.)

A study by the Federal Highway Administration shows that adaptive traffic signals can improve travel time by 10% on average. Intersections with particularly outdated timing plans can see travel time improve by as much as 50%.

Our client, Monroeville, saw travel time reductions of 20% when it installed adaptive traffic signals along the William Penn Highway (Route 22).

advanced traffic signals on Rt. 22 in Monroeville, PA

Adaptive traffic signals along Route 22 in Monroeville reduced travel time by 20% and the frequency of stops by 87%.

 

Adaptive traffic signals increase safety by reducing stops (and thus the opportunity for rear-end collisions).

Monroeville saw an 87% reduction in stops along the William Penn Highway after it installed adaptive traffic signals. It stands to reason this would prevent accidents, and data in other cities bears this out.

  • In Troy, Michigan, collisions causing serious injury were cut in half after adaptive traffic signals were implemented there.
  • Crashes fell by 38% in West Des Moines, Iowa, after the city installed an adaptive traffic signal system on the Jordan Creek Parkway.

advanced traffic signals can cut down on rear end collisions

Reducing the time cars spend stopped in traffic reduces the opportunity for rear-end collisions.

 

They tame the chaos that often occurs in unforeseen circumstances (like traffic accidents or special events). A conventional traffic signal system can only respond with pre-timed cycles – none of which are likely to be the best approach for an emergency situation like a lane closure caused by an accident or a downed tree.  Likewise, a special event may cause significant, unanticipated changes in traffic patterns that a conventional system could not respond to adequately.

An adaptive traffic signal system can rewrite the timing to fit the changing situation on the ground. Immediately. The moment the event occurs. (When necessary, municipal staff can override the timings manually– while viewing camera feeds from a remote location– to help emergency response times.)

They increase customer satisfaction and reduce complaints.

Drivers spend an average of 36 hours per year waiting in traffic – even more if they live and work in the city. This is frustrating, and people often complain to their representatives about the roadways where they wait the longest.  If you can reduce those wait times, you will reduce the complaints, as well, and relieve driver frustrations.

In the Harrisburg area, drivers have commented to us about how much better it is to drive on the Carlisle Pike and Route 22 corridors since adaptive signals were installed. Many have told us how they used to hit every red light, but now they cruise through a sea of green, making it to their destination much faster.

adaptive traffic signals reduce the time people spend in traffic

Make your drivers happy: Adaptive traffic signals reduce the amount of time people sit in traffic and saves them money on gas and lost productivity.

 

Adaptive signal systems save drivers money and reduce vehicle emissions.

Reducing delays in this way doesn’t just save drivers time; it also saves them money. A study by the Texas Transportation Institute estimated that Americans waste more than $87 billion per year on gas and lost productivity due to congestion.  That’s more than $700 per driver!  The Centre for Economics and Business Research estimates those costs will rise by 50% over the next 15 years.  But adaptive traffic signals can help us bring those costs down by reducing congestion and delay.

This will also reduce vehicle emissions, providing cleaner air for us all to breathe.

Where are adaptive traffic signals currently in use?

Over the past several years, PennDOT has been working with municipalities to implement adaptive traffic signals across the state.

  • In Central Pennsylvania, adaptive traffic signals have been installed at more than 40 intersections in Cumberland County and Dauphin County. The primary locations are along the Carlisle Pike and Route 22. Route 422 in Lebanon County and Route 501 in Lancaster County also have adaptive systems.
  • In Western Pennsylvania, adaptive traffic signals have been implemented along 18 intersections of the William Penn Highway in Monroeville.
  • In the State College area, adaptive traffic signals are being installed in Patton Township along Valley Vista Drive where it intersects with Green Tech Drive, North Atherton Street, Lowe’s Centre Driveway, and Carnegie Drive.   Adaptive signals will also be installed on the Waddle Road Corridor.

In fact, 3 percent of the nation’s traffic signals use adaptive signal control technology, and that number is rising fast. According to the Laboratory for Adaptive Traffic Operations & Management at Florida Atlantic University, the number of intersections with adaptive signal control rose by more than 40% between 2009 and 2014. Likewise, the number of agencies using them increased from just 30 to almost 150.  (The laboratory tracks the number of locations using adaptive traffic signals across the United State on a map.)

What does it cost to implement adaptive traffic signals?

The cost to implement adaptive traffic signal systems averages between $30,000 – $50,000 per intersection, according to data from the Laboratory for Adaptive Traffic Operations & Management at Florida Atlantic University.

Other studies by the Institute of Transportation Engineers and similar experts in the field have placed the numbers in this range, as well, but the cost can vary widely. (We found numbers as low as $20,000 per intersection and as high as $65,000.)

One reason costs vary is because adaptive traffic signal systems have many components, and each one has its own pricing variables:

  • New hardware and software
  • Detection devices (radar, loops, video)
  • Controller upgrades
  • Interconnection and communication changes (if intersections are not already interconnected)
  • Staff training
  • Traffic studies

The cost will depend largely on what brand system you choose because different systems have different software and equipment requirements. (Also, some require more training than others.)

The cost will also depend on the current state of your intersections. Many municipalities already have detection devices installed and have already interconnected signals along busy corridors. Costs to implement adaptive traffic signals at intersections like these would obviously be lower than at an intersection that doesn’t have these components.

Is there funding for adaptive traffic signal systems?

Yes, funding is available to help defray the cost of implementing adaptive traffic signals.

  • Programs like Green Light Go and Automated Red Light Enforcement monies could be used successfully to fund these projects in Pennsylvania. (Our article on applying for Act 89 grants provides more insight on the Green Light Go program.)
  • Full or partial funding could also be obtained through the land development process as traffic mitigation required during completion of a traffic impact study.
  • Federal Congestion Mitigation/Air Quality funds are another option that has been used in the past.
  • Other programs that could provide funding include:
    • The Commonwealth Financing Authority Multimodal Transportation Fund
    • PennDOT Multimodal Transportation Fund
    • Pennsylvania Infrastructure Bank
    • Pennsylvania Municipal Liquid Fuels Funds

In Conclusion

traffic signal
Even though it is a significant investment, adaptive traffic signals may be worth the cost because of the benefits they produce:

  • reducing travel time and stop frequency,
  • reducing the number of rear-end collisions,
  • increasing customer satisfaction,
  • reducing the costs of congestion (like fuel and lost time), and
  • reducing vehicle emissions.

Adaptive systems can also handle unforeseen circumstances like a traffic accident or special event traffic better than conventional systems can.

Municipalities who do implement the technology should budget $60,000 per intersection, but the actual cost will depend on the system the municipality chooses and the current technology deployed on its intersections (i.e. the changes or upgrades the intersections will require).

Funding from grant programs like Green Light Go and Automated Red Light Enforcement can be used to defray these costs.

GUIDE: How to Obtain Act 89 Funding For Your Municipality

Cover of HRG's Guide to Obtaining Act 89 Transportation FundingIn 2013, Pennsylvania enacted Act 89 to increase funding for roadway, bridge and traffic projects.  This legislation increases transportation funding by uncapping the oil company franchise tax, increasing fees for driver services like vehicle registration and license plates, and increasing fines for traffic violations.

Thanks to this legislation, local governments are already benefitting from an increase in their Liquid Fuels disbursements, but millions of additional dollars are available to municipalities who know how to access them. Act 89 funding is not distributed through one umbrella program. It is actually disbursed through several different initiatives:

  •  The Multi-Modal Fund
  •  The Green Light Go program
  •  Low Volume Road/Dirt & Gravel Road Funding
  •  A bridge bundling initiative

In order to obtain the money for which your community is eligible, you’ll need to understand the different programs and the application requirements of each. In order to meet these requirements, you’ll need to implement a long-term strategic planning approach like asset management and capital improvement planning.

This guide can help you do that. In it, we will tell you:

  • What types of projects are eligible for act 89 funding
  • What information grant agencies are looking for
  • Ways to position your projects for grant success
