Stormwater Management

Stormwater Management: 
It’s our responsibility and more…

Submitted by Cristin Tarr, Terracare Associates- Littleton, Colorado

Why should we care about stormwater management?  Originally, stormwater management involved primarily quantity of flow and now equally important is qualityof water runoff.  Since 1970’s, the EPA (Environmental Protection Agency) is responsible for managing runoffs in the United States.   The EPA utilize computerized mapping and models to best manage water runoff, erosion and pollution problems resulting from weather or other fresh water flow.  Because of these regulations, municipalities, counties and the private sector strive to achieve compliance and more.  Many local districts and even the Department of Health are involved in monitoring stormwater runoff.   Nick Madrid, Field Manager of public infrastructure division at Terracare Associates, a leading outdoor maintenance company says “Everything we do each day we consider stormwater management.  From our maintenance bays to washing equipment, to road repairs, we evaluate the effects on the environment.”  As a property manager or city public works department it’s important to understand how to integrate stormwater management into your ongoing maintenance strategy to achieve the highest level of public safety.

What is storm water management?

Traditionally, storm management is focused on collection of storm water through pipes and drainage transporting water runoff as quickly as possible to stream, creeks, rivers and sometimes sewer system.  However, storm water management includes anytime water flows at facilities, on roads, off of properties into water systems.  Erosion, debris, chemicals, sediment, salt and sand run off are all part of managing water flows that must be filtered before entering sewers or other fresh water sources.

As described by the EPA, the process starts with storm water, rainwater and melted snow or general maintenance water use that runs off land, streets, lawns, and other urban hard surface environments. When storm water is absorbed into the ground, it is filtered and ultimately replenishes aquifers or flows into streams and rivers. In developed areas, however, solid surfaces such as pavement and roofs prevent precipitation from naturally soaking into the ground. Instead, the water runs rapidly into storm drains, sewer systems, and drainage ditches picking up debris with it and can’t be absorbed as quickly.

Your Storm Management Plan – Best Management Practices (BMP)

To be EPA compliant it is recommended to follow stormwater Best Management Practice, also known as BMP, to take care of excess runoff pollution problems.  They recommend various control measures to reduce the pollution in a wide variety of water flow sources before it is absorbed into the ground. Another approach is to put measures in place to prevent pollution from occurring at all.  Facility Runoff Control Plan (FRCP) is a plan that offers stringent guidelines to reduce erosion, filters all water runoff and eliminates contaminants from entering sewers, detention ponds, streams and creeks.  Terracare Associates strives to achieve 100% containment and the company is continually monitoring anytime the flow of water is disrupted.  Terracare’s Nick Madrid has worked in the industry for almost 30 years and has seen dramatic improvements in maintenance of water flows “Every project we work on our team talks about stormwater management  and runoff.  Internally, stormwater is an active discussion on how we can best reduce contaminates from getting into the water system.”  To best maintain water runoff, there are several factors to consider:

1) Water flow Rate: Anytime water is disrupted from natural flow BMP’s are considered. Higher peak flow rates can result in erosion and more contaminates enter the water stream.   A higher peak flow rate requires more significant storm pipes and drains and continued maintenance.

2) Water Quality: “What goes in must come out”, this cliché is very appropriate for proper stormwater management.   Poor management of runoff with sediments, chemicals and silt could result in increased contamination and pollution in our waters, impacting fish and wildlife. 

2) Storm Water Volume: A larger volume means greater destruction and erosion of creek beds leading to bank instability, increase sediment deposition in the lower reaches, and loss of habitat.

4) Ground water: If groundwater is not allowed to recharge, base flows are reduced leading to longer, drier durations in ditches and streams.

Goal of good Water Management Strategy

Educating the public and training employees is critically important.  Maintaining current infrastructure can also be valuable in maintaining a healthy and safe environment.  A plan should be made for every project to mimic nature by integrating stormwater management maintenance into building and site developments to reduce the impacts that urbanization has on our natural resources.  Greg Hayes, Colorado Operation Manager of Public Works for Terracare Associates believes “ Whether it is storms or fresh water runoff we have to be diligent about how we manage water, it goes beyond our operations, it’s about public safety and the environment.  We tactically discuss BMP’s as projects are implemented”.

Typical Best Management Practices (BMPs) may include:

• Equipment maintenance activities should be performed inside when possible.
• Spills should be cleaned up immediately & without water whenever possible
• Floor drains should be sealed and separators installed
• Increasing topsoil and enhancement to slopes, rocks and inclines near roadways
• Infiltration trenches and storm gates
• Storm drains cleaned and maintained
• Pipes, curbs and gutters minimize cracks and other damages
• Detention ponds
• Ditches and Creeks creating easy flow for runoff and less erosion

Safety is the number one concern of storm management practices. The importance of storm water management in the reduction of flooding and contaminates getting into the water system cannot be overemphasized.   Hayes says; “This is the way we do business, it goes beyond regulations.  Public safety and protecting our environment is what we believe and the way we conduct business every day at Terracare Associates”.

“Smart” Irrigation Controllers - What Property Managers need to know

Submitted by: Shawn Gevedon, Irrigation Manager Terracare Associates - Colorado

Smart Controller Basics from Terracare Associates on Vimeo.

Property and facility managers have a lot to think about.  Finding innovative solutions that make business sense and at the same time help our environment can be a challenge.  Water, one of the increasingly precious resources is top of the list.  Here are three facts that you need to know about Smart Controllers to help you make the decision to install this high tech tool at your property.

Fact 1: Technology improves irrigation efficiency.   

So called "smart" irrigation controllers have appeared on the market for use in residential and commercial applications since the early 2000's. The Irrigation Association (www.irrigation.org) defines "smart controllers" as controllers that reduce outdoor water use by monitoring and using information about site conditions such as soil moisture, rain, wind, slope, soil, plant type, and more, and applying the right amount of water based on those factors. Essentially, these irrigation controllers receive feedback from the ET Data and schedule or adjust irrigation duration and/or frequency accordingly. For example, they would reduce watering in the cooler months and increase watering in the hot and dry months while conserving increasingly limited water resources. There are generally two types of smart controllers: climatologically-based controllers and soil moisture-based controllers.

Fact 2: Smart Irrigation Controllers are getting smarter.

·         Climate based controllers are also known as evapotranspiration, or ET, controllers. ET is the amount of water lost from the soil through evaporation plus the plant's water loss, both of which are dramatically affected by weather conditions.

·        Soil moisture sensor (SMS), Soil moisture sensor smart controllers rely on the amount of moisture in the soil, measured by buried probes, to determine irrigation schedules.

.

Fact #3 The Smart controller capital investment pays off

Reduces water costs:  Studies show most smart controllers will save 25 and as much as 57% of the water costs annually. This is a significant water savings because, outdoor water can be as much as 70% of the total properties water costs in some regions of the U.S.           

Rebates and Incentive Programs:Many local water districts offer rebates for installing Smart Controllers.  Customers have realized a one year return on investment after rebate and annual water savings (Case Study: Bowles Crossing)

Increases water efficiency-“only use what you need” the cliché is true, technology of smart controllers designs the most efficient systems to maximize plant care and minimize water waste and runoff.

Environmentally Responsible– If reducing your water bill, receiving a rebate check or maximizing water efficiency isn’t enough, consider installing a Smart Irrigation Controller, because it is good for the planet.

Let's Talk About.....

Greg Hayes – A leader in motion

Submitted by Cristin Tarr, Terracare Associates

What do race cars, a deputy, and mentor have in common? Greg Hayes - Colorado Operations Manager for the public infrastructure division at Terracare Associates. I had the pleasure to sit down with Greg Hayes to talk about his 30-year career with Colorado Department of Transportation (CDOT) and his current position with us at Terracare.

As past Deputy Maintenance Superintendent of the front-range region, Greg was responsible for 250 state employees, over 100 large trucks, 600 pieces of equipment and handling almost $30 million dollars in annual projects. His reputation for organization management, dedication and integrity was well known within the walls of CDOT.  His list of projects includes HOT lanes, T-Rex of Colorado and many major highway interchanges. Nothing is more precious to him than his employees. “Safety of my work teams is so important. We want our field employees to come home safe and healthy every day. In addition, our goal is to make our roads as safe as possible during any construction projects. Public safety was and continues to be always on my mind.” 

Fortunately for Terracare Associates, after Mr. Hayes’s retirement from CDOT he joined Terracare’s public infrastructure division team in October, 2013.  “We have known Greg for some time. We knew about Greg’s reputation as an exceptional leader, commitment to quality service, work ethic and breadth of experience in public works. We are privileged to work with such an exceptional person on our team,” said Dean Murphy, President, Terracare Associates. 

During my conversation with Greg it was apparent he was unassuming and reserved about his achievements and often gave credit to his team members.. Greg began his love for infrastructure at age 13, helping his uncle’s construction company in Arizona. He was quite young when he first handled heavy equipment, and he was hooked. I asked him what makes a great leader. He states “taking the time to mentor and teach the young people what you know, sharing your knowledge of what you've learned is the greatest gift you can give as a leader.” He feels strongly that mentoring those that are less experienced helps build a road map (no pun intended) to the next generation. 

Ironically working on the road doesn’t stop at his daily job. Greg is co-owner of three race cars and competes almost every week in season. In addition he has six show cars and he loves the outdoors. His passion for mentoring is extended to his three children 28, 25 and 14 years old.  He coached youth sports, football and basketball for many years. Greg is always on the move inspiring and empowering others to be their best. Greg is continues to be a leader at Terracare Associates and is moving the pack forward...even on the racetrack.

Commercial Landscape: 
Five Steps to Maximize Water Efficiency

Design your Water Management Plan:  It’s Time!

Submitted by Nick Vizcay, Account Manager, Terracare Associates, Martinez

“Drought” is the scary word for municipalities, property and facility managers especially in the Western United States due to its severity and the multi-year impact on regions. The challenge is to create an aesthetically beautiful landscape, while working with significant water restrictions.  In 2014, California’s Governor Brown declared a statewide drought emergency asking all Californians to reduce their water use by 20%. Similar drought situations plagued Colorado and Utah in 2002 and 2012.  It does not seem there is an end to water restrictions; water management is the new norm. (See USA Drought Monitor)

 

Caring and taking action about our individual and collective water use is environmentally responsible, but maximizing water efficiencies can also be a significant savings in water costs.  Landscape professionals need to work closely with property managers to help evaluate, install, monitor and manage their irrigation systems.  Managing expectations and educating property managers and tenants is key when transitioning to a true water management program.  Here are the five steps:

 1. Education –Most public and commercial properties can benefit from a variety of water reduction modifications.  Understanding what is optimal for your property takes some commitment to learn about best practices, innovative irrigation tools and accessibility to resources for better water conservation.   Replacing heads and nozzles, utilizing flow sensors and installing smart controllers are a few of many options to review.  Learning and working closely with your irrigation specialist will help you save money and conserve water.  Ask your irrigation specialist about any rebates your county may have.  A great way to start is to participate in water management seminars to contact us to  learn more>>>>.

2. Evaluate and Audit – Start with a bench mark.  Find out the challenges to the current water system, water runoff, leaking pipes, damaged nozzles etc.  Obtaining an irrigation system evaluation and water audit is a critical first step to assess current systems and determine how to improve management of outdoor water systems. 

3. Design – Working in partnership with your irrigation manager is important to build the best and most efficient system.  The design would review and may include budget constraints, scheduling, nozzle conversions, water flow, soil management, plant removal and replacement (i.e. xeriscape), rain sensors and smart controllers.

4. Implement- Once the design is complete the fun begins with implementation of the changes and enhancements of the water management project. Implementation can be in phases and is focused on maximizing savings and water efficiencies from day one of installations, repairs and replacements.  The goal is for the capital investment to pay off as early as possible and in some cases cost savings are realized (with rebate programs) within a year.

5. Monitor - Finally, overtime your landscape company continues to view water flow and inspect for leaks and nozzle repair.  In addition it is important to track and measure the effects of your water efficiency updates. Local water districts help to monitor usage and costs.   Questions to ask:  Is less water being consumed each month or year over year? Are the investments in water efficient updates to your property set to pay off, when?  Check out rebate programs, cash for grass and installations incentives at your water districts or cities where you reside.  You may be surprised how lucrative they can be on large properties.

CASE STUDY:

CLIENT:         Silverado Springs HOA

DATE:            October 2013

PROJECT:     Remove approx 20,000 sf of turf, Install drought tolerant plants, Convert irrigation to drip, Install bark

RESULTS:   Saved approx. 256,000 gallons of water YTD

Drought restrictions are serious, but less apparent as we all have easy access to water.  The United Nation 2012 report stated that only 11% of the population has easy access to clean water.  A Water Management Plan is not only necessary, it saves money, water and is responsible.  Start today: It’s Time!
