Was a project manager for the home building industry in Sacramento Ted was the principal author of the updated Green Acres landscape code in 2011 so without further ado I am going to transfer the screen over to Eric power who’s going to do a quick introduction and then we’re going to get things

Started so Eric it’s off to you Thank You Christine good afternoon everyone my name is Eric power as you’ll see on their screen there it shows Eric Ted mr. Kovac is here in the same room with me today sustainability is and has been for some time the hot topic and planning how

We can prepare our communities for tomorrow if you’re like us you spent a good amount of your day putting out base fires and not enough time planning for tomorrow this is why it’s important to has the conservation conservation conservation conversation that we are having today so our landscaping is not

Lost in sustainable discussion after all what is more sustainable than a tree they can live for hundreds of years it provides us so much from the vital task of producing oxygen to animal habitat the simple beauty they bring to our communities today we hope to give you a

Comprehensive view of the role of a landscape in the plan of life we hope that the information is helpful and decision making that point may today will give you tools you need to include landscaping and your community sustainability plan but before we begin I just want to take a brief

Moment to tell you about the organization i was able to bring you this webinar today li AF with landscaping scratch association of florida is an organization that provides education and certification training to those who work within the landscape field we are the champions so to speak of the florida grades and standards this

Is a guideline put forth by the state to ensure the quality landscape materials used it covers everything from trees to palms two trucks our members are anyone from landscape inspectors nursery owners installers property managers code officers landscape architects master gardeners and yes even planners now this

Was some fun here some of the problem that we see out there doing our inspections everything from half-rack trees and for root systems to well I really don’t know what to say about these slides other than sadly yes they are real and anyways with that I would

Like to turn the presentation over to Laura stanag or she you okay good afternoon everyone thanks for sharing part of your day with us this afternoon so I’m going to talk to you a little bit about the planners role in landscape sustainability and specifically how the human element plays

Into sustainability before we get started I always like to know who I’m talking to since we couldn’t really shake hands and introduce ourselves at the beginning of this webinar so we have two quick polls just so we can get a feel for who you are so if Christine you

Could please put the first one up we’ll just ask you to respond really quickly our numbers are still moving around so I’m just going to wait for one more moment just so that you can make sure that everyone is able to vote okay there we go I’m going to go ahead and close

This poll okay interesting so I just wanted to see what some of the major environmental concerns are in your community and it looks like water quality is a huge one for three quarters of you but not far behind that our water quantity and air quality erosion and wildlife habitat

Interesting and real quick we’ll do one more poll if you could please Christine if you could tell us about how your role has changed in the past five years if it has you okay I’m going to go ahead and close it this one is very clear I suspected it

Might be okay Thank You Christine that is interesting not particularly surprising to me but I guess we could say that the majority of you that are participating today have a lot more responsibilities then you did a few years ago and also you’ve got some major environmental issues so have a few

Things in common I also suspect that many of you are on this webinar because your new responsibilities include a landscape review so anyway um thanks for participating there so the planners role in landscape sustainability you might or might not see yourself this way but when when you’re working on landscape

Planning projects you really are a community change agents and you have the opportunity to make a lot of changes in a positive direction towards sustainability but that comes with understanding people which is not always easy and as you know you require to be a subject expert but you also have to wear

A lot of hats so a couple definitions of sustainability that i really like but sustainability is retaining good characteristics of the existing situation and improving undesirable or poor characteristics it’s also improving the quality of human life while living within the carrying capacity of supporting ecosystems so I think these

Are two that really represent what we do in the landscape and this is what we’re up against here this is a an example from Florida but we’ve got some some great native vegetation we go in and we take out the great vegetation and and the wonderful native soils and we put back in

Much smaller versions of you know what we may have taken out so this is not necessarily the most sustainable way to go about things as we’ll talk about a little bit more later landscaping really does affect the environment and both the initial design as far as what is

Installed and planned through how the landscape is managed affect everything from water quantity to water quality availability of wildlife habitat and air quality so when we look at planning a landscape for the future these are things to keep in mind I’d ask for a raise hand if we were all in the same

Room together but just an example here of a water quality issue if you notice these landscapes here well the lack of landscaping here has caused some water quality issues in this picture that are visible from very far away so anyway the planned landscape and sustainability when we design landscapes were really

Contributing to the quality of human life which is a pretty important role to play and there there’s a just a plethora of information on the benefits we get from well-designed landscapes as well as trees these benefits range from food to reduction in crime actual money savings increased dollars spent in an area

Social interaction outdoors emotional and physical health and emotional security and a good environmental image gives its possessor an important sense of emotional security he can establish a harmonious relationship between himself and the outside world so that’s what we get to do when we design landscapes is provide these benefits

Adults and children have been found to spend more times up more time outdoors in while design landscapes they result in so stronger social ties and an enhanced sense of safety and sense of place trees and other natural features help to create and maintain a sense of place that is a feeling of

Identification and belonging that is important to people’s enjoyment and well-being and to the process of community so when you’re working with a very diverse group of people there are a number of things that come into play with what they’re going to ask for and you can keep some of these things in

Mind when you’re dealing with the residents that you work with your colleagues your supervisors administration because there’s a lot of things that go into play and it’s not decision making is not always black and white as to what is sustainable so I’ll tell you about a couple of these

Decisions are mitigated by these unseen barriers and benefits so whatever behavior we’re talking about that that we want people to adopt to be more sustainable there are these unseen barriers and benefits that are going to come into play and the key is that they’re unseen so we have to kind of be

Detectives they can be perceived or real and they could be internal or external and what it comes down to is people may not adopt sustainable practices for certain reasons they might not be aware of something they might think that the barriers are too great they might know

About it but they think the benefits to the way things are currently being done outweigh the benefits to changing or maybe they don’t know about it so just an example here let’s talk about a new behavior which would be removing turf grass and installing native plants I

Suspect many of you that are on today might my deal with this is a means to use less water in the landscape so that would be the new behavior the existing behavior would be to continue to maintain the landscape as it is so every person might have a

Different set of these but you’ll have perceived benefits and perceived barriers some of the benefits a resident in your community might perceive to doing this is increased wildlife habitat more color in the landscape some of the barriers that they might see to this behavior is that maybe they don’t

Understand the benefits or they’re concerned about a loss of usable space so as a change agent in the community what you would want to do is to try and understand these barriers and benefits and to help encourage a change to more sustainable behavior you would want to enhance the benefits to making this

Change and reduce the barriers so for example you could educate on the benefits of installing native plants likewise the existing behavior there’s a set of perceived benefits and also a set of perceived barriers and so you can use these and use an understanding of your audience and clientele to help encourage

Behavior change a second factor that mitigates decisions as that of social norms and I thought that this quote really just kind of says it best but the promotion of a cultural norm through mass media and marketing material that focuses on the desirability of a neat and we tree lawn rather than beautiful

Outdoor landscape is almost certainly responsible for your care practices that threaten the environment and also reduce homeowners ability to enjoy the benefits of nature so social norms really play into the decisions that we make every day we want to be approved of and we want to do things that those

Around us are doing and this is a cartoon I like that that kind of I think is a good example of this but you know sometimes we have this idea that we’re all we’re all going green and doing what our neighbors are doing but it’s maybe not the most sustainable thing so I

Think this is a good example of that there’s been a lot of recent research on social norms recently and there is a very strong predictive relationship related to what a person’s neighbors are doing so they’ve shown an intention to install a rain garden associated with social norms within a community that the

People who thought their peers approved of installing a rain garden were much more likely to do so and another study has looked at those preferring environmentally sustainable designs are those whose neighbors had environmentally sustainable landscapes so it’s important to keep in mind that that are our clients and the people that

We work with are really looking to their neighbors and this is kind of interesting homeowners preferred landscapes that matched a broad cultural norms but they’re more likely to go with what matches neighborhood norms than cultural norms so what this comes down to is you want to look at the the

Small-scale the neighborhood because that’s where the the relationship is the strongest and really there’s a social support needed to encourage new behaviors and this kind of already but one of the best predictors of whether respondent does certain tasks in their landscape such as applying chemicals or doing maintenance himself has to do with

What they believe what the resident believes their neighbor does so using a social norms approach to encourage more sustainable behaviors would mean that we publicize sustainable practices that are being done in the neighborhood this can be done through signs and other ways to emphasize is positive social norms and

Make it more visible within the community fear plays into a lot of our decisions here in Florida we deal with a lot of hurricanes and each of you has your own natural disasters that you deal with but we see a lot of folks make decisions based on fear it can be valid

Fear it could be fear of changed it could be misplaced fear one of my favorite examples here’s another hat rack tree for you but we see people doing this all the time and it’s this fear of damage from large trees on one’s home or property that leads to

Unsustainable practices we know a lot of people call this a hurricane cut and they think it’s something that is going to make them safer the way that the tree actually regrows after cutting it this way makes it more dangerous and people have been very severely injured because

Of practices like this and so that’s that’s an unsustainable practice sort of driven by fear and I always like to share an example from a village in India that planted all these trees and when the tsunamis came through they planted all of these trees to break a world

Record when the tsunamis came through or the tsunami they sustains pretty much the least amount of damage in this area because of all the trees so the trees can actually protect you from storms when they’re planted properly so fear definitely plays into it stages have changed is something else that mitigates

Decisions just something to keep in mind people are in different stages have changed related to specific elements of sustainability so it’s not black and white they either do it or they don’t someone may have no awareness or intention to do something and that would be a pre contemplation

Stage so if you’re trying to encourage some element of sustainability your goal would be to raise awareness so they can actually contemplate that change it it’s good to understand that people are in these different stages and understand that there’s steps that would be taken to adopt a more sustainable behavior in

The landscape something that can encourage folks to be more sustainable is a technique of commitment so when we ask people to do something it changes the way they see themselves and it works because we as people love to be reliable so this is something that can be used to

Help encourage sustainability in your local communities and I won’t have time to go into this in too much detail but I wanted to close my section with just a quick example that I love I’m sure we probably have people from Maine on here and I wish I could see who you are but

This is an example that I love from the town of Camden Maine which is a beautiful place but they’re encouraging town residents to pledge to have chemical free lawns and they’re using social norms and this idea of commitment to encourage this element of sustainability and you can check out

Their website but here’s a map that you will see all over this little town and the green indicates the properties that have pledged to have chemical free lawns so it’s pretty interesting this encourages the social norms because you can see that your neighbors are doing these sustainable behaviors and it’s

Also an element of commitment because you’re up there on the map if you’ve committed to do this pretty interesting so just kind of in summary on my part I just went very quickly over a number of elements that sort of are playing in the background when people make decisions about

Sustainability but as planners you have the opportunity to act as change agents as well as subject experts but it’s important to understand that the people side of things too and people act or don’t act based on these barriers and benefits norms fear stages of change and commitment there’s some others but but

You’re really in a great role to encourage sustainability by affecting the communities time spent outdoors social ties sense of safety in place and emotional and physical health so with that I will thank you for your time and I will turn this back over well good afternoon thank you for all

Joining us today this is Ted Kozak cydia Green Acres and just wanted to give you a little disclosure right now I’m fine but if I pause for a moment I’ve had some issues of coughing lately ever since last Thursday and going to the miami heat game losing my voice and we

Also lost some other things just made some enemies right now i guess but so that’s my disclosure i want to spend a little time here first off green acres in palm beach county is city of around forty thousand with green acres is on a lot of major thoroughfare so we have a

Lot of commercial development a little more even more than cities the similar site wanted to spend a little time introducing technical aspects of landscaping planning and planning realm like laura just talked about you know more the psychological effects fear the like what i’m going to talk about or

More hard numbers most of us can recognize difference between well-designed and landscape and a 4-1 you know like this what I have up here on the screen an example we know on the left at that that looks ugly on the right how do we get there how do we you

Know with the challenges of power lines as you can see by the roadway this simple things to do to just bring properties a little little better looking but how it is important for sustainability in the environment it’s so basically the I’m going to give us some following tips and have just to get

Long-term sustainable landscape this isn’t a new concept by any stretch of the imagination I like to bring up some of the the planning history I in South Florida help teach the ICP planning exam in twice a year on plan making so I like to bring up things like

Nizar Howard garden city 1898 it’s basically was a push back and alternative to all the crowd II ugly on healthy cities as you can see here you know providing like Laura talked to burgers psychological benefits and reducing things such as crime for example just just due to the psychological parts of that also

Planning and landscape integration originated back when with old stand and Elliott it waiting from the turn of the century it basically all recognized importance the green space is how these places were sustainable in terms of population in environmental balance and also another key person in the planning

Realm a kevin lynch and its image in the city just touched upon lately it is you know a pop a little further on but the APA has been bringing this up a lot lately sustainability to next year’s conference in Seattle would be heavily involved in that as well as the the most

Recent finding magazine is talks about things and refers back to Kevin Lynch the importance of landscaping in terms of path its edges districts nodes and landmarks for a vibrant and healthy city basically that makes a sustainable city and this Laura talked about fears and the psychological benefits of people

Defame the finer space is based on their landscape so basically not only trees or a tree can be considered you know a landmark for people but it provides in districts and also definable edges in cities the light pole that Laura conducted obviously reinforces I’m bringing up here I’ll have expanded

Roles as a planner and basically where the the key for a lot of the Clean Water Act the Clean Air Act’s Safe Drinking Water Act shared responsibilities with on funded mandates in a lot of these agencies and it all trickles down to the to the local and regional planner at

Times even in the private industry basically planners are the advocate for the sustainable management of these resources and we are stewards of the environment and we with changes in public policy and an individual behavior landscape involvement is one of those memes of responsibility as I talked

About a second ago the APA’s and you know for many years but even more recently basically had a role made this a priority for example this a portion of this policy document from 2000 talks and directly on the biodiversity of the National Environment contributions that makes and human life things that what we

Were talking about earlier with Laura as well as our objective to sustain the ability of natural systems provide life supporting services and they’re rarely counted by an economist but you know these things are all make up to the gross human economic product more than we know and once again I’m going through

My emails yesterday and yesterday’s AP a monthly blog on sustainable and sustaining places there was healthy on health care and discussed things like open spaces tree canopies and other concepts associated with positive health and so it really a lot of overlap going on so how do we get here one tool for us

To become more sustainable is right your ear i played choosing plans that suits the existing site conditions as well as minimizing fertilizer pesticide and water use of sake that’s what sustainability is planners can use their knowledge about the site make sure appropriate plants are being planted I’m

Talk about a little later on how we can do this planners conduct these landscape inspections later on in after installation hopefully right after and immediately after a few months later just to make sure these issues do not become a problem in the future there is a you know visualize the street any

Street you you drive on it key to have you no drainage plan review and coordination other departments we just need to imagine the ultimate size of the mature tree not just current size here we’re seeing more of them the mature size trees don’t grow as large as they

Do in the natural environment however they they still grow trees are living organisms so we need to plan for we need to adequate space to grow and the fairer minimum is seven feet clear a lot of tree species need a lot more than that but even our new parking code requires

۱۰ feet terminal islands and parking lot is at the very minimum giving room to grow basically in the future if this isn’t done we eventually have to remove these trees due to conflicts in the air we start all over again we’re forced to basically not doing what we’re trying to

Achieve there are a lot of things that affect the health of the tree basically a roots and limbs there’s commonly overhead power line utility conflicts sidewalk hi Dave day or is a great reference book I like to bring up is up by roots by James urban a landscape architects it’s obviously very technical

In very thick but flipping through it pick up a lot of tips may be going through and end up making zoning code amendments and or even just making policies it discusses basic soil soil silence science and tree biology planning and implementation landscape design it’s just important to realize

The area beneath the ground the root zone which this book is talking about is just important as important as the overheads space and according to the ISA the international society of our Bora culture as many eighty percent of landscape plant problems may originate below the ground in the root soil system

So obviously that’s the main concern and here we can see the Greenville South Carolina Main Street James urban was helping reinvigorate if you will Main Street was designed in the 70s and at the time trees had been going into decline basically due to these tree wells not being sufficient and so

Suffice back in the 70s this thought wasn’t going into providing the room as we do today so instead of costly and time-consuming repairs and replacement projects doing it correctly the first time is far more efficient and hopefully as we can help trigger a little bit us

In your mind as we go today an example we see all the time planning for the mature canopy and in route space sidewalk we’re constantly seeing them being lifted the 7-foot role would be nice to get there are other ways around that if you cannot you know these green

Spaces between the sidewalk and the curved line you know maybe provide some routes own protection and the like but in the end trees will find a way and then on the right planting trees with lower mature heights are important under power lines South Florida we have you

Know the word blessed with a lot large range of trees available that maybe we have more of a selection but any in any environment there’s a possibility so basically later on we reduce conflicts by from providing with flexible material and here’s an example as walking around Key West last month concrete sections of

Sidewalks that have been replaced with rubberized material to protect the root zone I know all of you and you go to Key West you take pictures of sidewalks like me but I noticed this you did there’s a large large role in the tree canopy there and it’s very important so one way

To get to this point is replacing sidewalk base and sub base with structural soils I don’t get technical on this other than it’s a way to make men made solutions on compaction and providing more room for the roots to grow I know we all see this kind of

Thing right you’re right place well as the power company has to come in and make drastic amendments to the crown and over time this is going well it’s already a problem but now we see this in every city we need to plan for it up front and then utility companies are

Forced to come in later and make a natural community no matter where you are we you know recommend native not non adapted species basically non adapted means is you know anything that was not here before Columbus came so typical things that we find soils don’t match

The tree species that are in the ground oaks with nitrogen deficiency here on the left and alder with phosphorous typically you know there’s the new trick nutrient deficiencies or related back to high ph soil queen palms they’re from Brazil they they show basically manganese and magnesium deficiency giving dead tops basically since roots

Require oxygen to conduct biological processes to grow and most roots grow within the first 18 to 36 inches of the basically the top of the root zone it’s critical to plant trees at or slightly above the grade here you can see the correct way in the left the first

Or two roots they’re a little slightly above but planting them too deep on the right basically will suffocate the roots and eventually decline and die it’s not going to take long during planting straps and support they strangle the trees here you can see in the right strand removal should occur less than a

Year after installation just depends on the storm season but many publications including the ISA does not even require or mandate staking there’s a lot of times if it’s a native tree i I really don’t need the for a pine tree to be staked it’s a lot of times people do not

Come back and take them away and eventually the tree just it irreversible damage and again here’s the root ball you know don’t pile a bunch of mulch on top of the roof zone during great after planting a little business of the roof all above the ground and the the native

The parent soiled and actually you know excavated as little as possible but as wide as double as the roof all and of course you know we’re out there whether you’re in the private industry or even just being a watchdog for during a landscape inspection or even during

Lenses as a site plan process quality landscape begins with the quality plant material most I can’t say most but a lot of states have the state grading programs and if not you know it’s worthwhile to create landscape codes that trait state grade number one or better codes like this state of Florida

Has a book the grades and standards regulatory document which has practical research-based information about quality of trees shrubs another landscape plant there’s a lot of other states like California Illinois and that have strict guidelines for nursery stock I just check into that if your state does not it’s a great way to start

At the beginning during construction or planning for it on the tree preservation is critical I mean relates back to the root zone during all phases of construction protect them from Nick mechanical damage that it will basically kill off the the means for producing energy and nutrients for is the tree and

Uptake a minimum minimum 1 to 10 distance ratio for the construction fan so this is a one from diameter a tree a 10-seat away from that trunk for protection but the drift zone is really the optimal location here in the rightist tree preservation survey in a protection detail you know typical one

Just feel free to copy one from somewhere and then later on it what we call with managing pass responsibly implementing integrated pest management program it’s just as simple as the first planners to be aware that once the project is approved the construction completed that there is still more to be

Done you know optimally we want to follow up we want to allow others to reduce and manage costs and maintain healthier landscapes yeah if if you’re able to monitor and on a regular basis you know no matter what you’re doing just don’t wait until the plans are

Obviously under stress to the point to decline which then will require immediate and usually drastic overuse of chemical applications such as pesticides so things as simple as conserving with using beneficial insects or even other organic means is that you know even using organisations such are your

Or your state extensions of the key so planning and leaving room for recycle waste just leaving grass clippings leaves compost on site and returns nutrients to plants and reduces waste you know leaf litter is free fertilizer back in the the forest way way back when before there was no urban landscapes

This is how nutrients were were recycled and mixed in there was no need for Pharrell of eyes or obviously we recognize the current situation and not as feasible in all locations except maybe a park so again post-project mentioned practices are key to long-term viability as well as reducing the

Constant plant replacement we can encourage landscape ways to be recycled the key is to save money increase to help the plant now here’s something that we’re in at least I see almost on a daily basis and if not come it’d be something for you to get to know things

To look for in the landscape plan really this is bringing everything together with what I’ve discussed the comparing this with other plans like civil plans with pisces tivities and overhead power check with the dimensions on here in the site plan to make sure that the the dimensions actually match this there’s a

Lot of times that come across plans that there’s a berm and a swale in the same location that when you do the map that doesn’t actually work so you know it’s either going up or it’s going down so so we’ve key to compare the two checking species suitability for mature size

You’re looking on this landscape plan let’s make sure the trees not too large for the bare minimum escaped Terminal Island that’s provided and then things like I talked about checking suitability for the type of soil the soil pH and then even things like sunlight and not planting sunlight

Loving trees on the north side of the building and then of course the suitability for the climate zone the too hot or too cold too wet to dry for the type of plant don’t plant a lot of moisture loving plants and Phoenix what you know that’s obviously not going to

Work as well as planting a palm tree in somewhere in north dakota so you know the thing all these things may sound you know obvious but bringing hopefully these ideas to forefront today do these some ideas on what to look for and with that I’ll leave my information up here

And pass it back to Kristin thank you very much for listening you Thank You Ted and get acne to get everyone this is eric tower i’d like to conclude today’s presentation with a discussion about landscaping to encourage sustainability in some not so common ways mainly by touching on these three topics green infrastructure

Repurposing of stormwater and traditional habitats today’s seminar was about the use of landscape and requirements and while my topics are probably more related to engineers it’s important to remember that planners often have unique role of being the middle ground with mediator and projects and that these topics are important

Planners because the use of landscaping has a beneficial impact to a city or community to start I just wanna shows there are several organizations out there anti government entities are trying to incorporate landscaping into sustainability now these ideas are not just those the tree huggers speaking to

You today we all know lead of course which is really the forefront runner and sustainable buildings but I think it’s important to note that lead does provide credits for the use of landscaping and green infrastructure and these are often overlooked when seeking certification lead however is not the only player in

The sustainable game site for instance is an organization that wants to provide certification to properties that use landscaping to regulate clean air and water furthermore states like Florida have instituted programs such as florida-friendly something that’s that temperatures talking about which encourage developers to think about all aspects of landscaping from water used

To habitat associations like the ALC a which is an equivalent to LIF in Arizona have adopted sustainable landscapes game centers and the federal government’s through the EPA of course is creating policies and providing a lot of grant money to bring landscaping into the forefront of a sustainable conversation

So let’s start with what I believe will be the next big buzzword in the sustainable conversation and that’s green infrastructure the EPA’s definition is in front of you but simply put green infrastructure is using vegetation help clean and process stormwater or any other contaminated water source its counterpart gray infrastructure is

The existing process of storm pipes and gutters used to funnel water runoff it’s less intrusive in the community it can provide virtually the same results that gray infrastructure treatments can have and at the end of the day it just costs less to build and maintain is virtually more appealing and can have multiple

Secondary effects such as cleaner air ditional habitat and community space the only real knock on green infrastructure is people’s unfamiliarity with it something that is lower points about earlier in our segment can be a real problem in making the decision to act on sustainable design just a couple quick

Case studies here about what’s being done across the country Philadelphia has been a nation wide leader in green infrastructure for some time now and their current long-range plan is it simply remarkable over the next 20 years Philadelphia plans spending over a billion and a half dollars in green infrastructure improvements on things

Like rain gardens green roofs pervious payment and things like that to irrigate trees in to protect our stormwater New York is taken on a similar task is Philly while not as all-encompassing the arguments that New Yorkers trying to make with this plan is to as residences cost savings this is an important

Selling point to what is perceived in some that sometimes as a new and unproven technology but in reality these programs are just using trees to do is mother nature intended I’m not going to be able to spend all of today discussing the many different types of green

Infrastructure but i do want to touch on Green Streets which is probably the most common green infrastructure practice you have heard of to make a street green does not involve more than just trees it does need to make sure that the trees only a chance to survive but that their

Contributors to the overall appeal to Green Street concept and while serving a purpose which is the collection and treatment of stormwater these photos are commonly referred to as tree pits but bioretention tree wells rain gardens are often used to describe them as well I feel the tree pits are more appropriate

Term if they are actually lower than the greater the sidewalk or the roadway and what this allows for is for the roots to grow underneath the infrastructure it’s more room for sidewalks and benches allows the store water to actually be retained in this area and of course provides that storm

Water to irrigate the trees instead of sprinklers and you know of course the trees get the chance to thrive in the environment as opposed to a smaller tree great here is a construction photo of what these areas look like prior to install what I think is important to

Point out is how the size of the area that these men are working on is about twice as large will actually be seen above ground this allah roots get a chance to grow within it without impacting what’s above them municipalities counties and transit departments need to recognize they are

Not prop theirs they and not the property owners are the first step to creating complete Street government entities are going to be creating the Green Streets the purpose of stormwater reduction in water purifying but unlike gray infrastructure which is underground seldom seen the Green Street provides that beautification that makes the

Street stand out a well landscaped street can do numerous things from increase in property values to reduction speeding cars this is a cross section of a sixth Street in Milwaukee near their Airport it’s Milwaukee’s first spring street the storm water from this area flows into a place called Wilson Park

Creek which is a concrete channel for flooding as this area is prone to flooding and heavy rains so the goal is that this green street can not only prevent large flooding but also can clean the runoff that is going into the green areas okay so why bother there’s always stormwater stuff anyways right

What is the purpose of creating a green street the answer is really in what is happening to stormwater runoff right now in that particular community is it being treated is it going right into a natural area carrying with it its harmful chemicals and bacteria the green infrastructure initiatives may have

Benefits that we all can see like a reduction of construction and maintenance costs beautification and so on but its real purpose is to reduce the amount of pollution that flows into our waterways quantifying its ability to do this will ultimately what makes or breaks this movement

Here we can see a nationwide view of runoff while state such as Oregon Washington Florida and New York are dealing with storm water because of its abundance repurposing is something that states should be considering as well and here you can see similarity in the areas of where surplus and deficits exist so

How much impact the storm water runoff really have in the community well as you can see in a rural area it’s about a 50-50 break between infiltration and runoff can buy with evapotranspiration a big word meaning water loss of the atmosphere more so in human cases like

Today here in South Florida but of course the residential low and medium density areas you know they have a little bit of infiltration but it’s truly the urban area where you can see the difference between runoff and infiltration but more than half the storm water leaving the area is flow

This is really why major cities like Philadelphia New York are taking green infrastructure so seriously it’s because there really isn’t any place for the water to go do the city’s massive impervious footprint what makes contamination a problem is that storm water systems are designed prevent flooding which of course is very

Important in fact I was just listening today an NPR about the flooding concerns in the middle of the country but by moving the water out as quickly as possible we then not only lose the ability to repurpose it but we lose the ability treated as well and the problem

With that is you saw in the last slides is that water demand the United States is triple the last 30 years global demand doubled every 20 years and the current stormwater practices that we have in united states are not meant to retain um i also want to point out storm

Water isn’t the only culprit when it comes to contaminating waterways residential lawn care is actually when the large water wasters our country’s currently dealing with now this is a last-minute addition to my presentation I so just the last night on my way home and I just had to bring it up today

South Ford’s is doing a lot of rain the last two days and even though it rained non-stop yesterday the timer to this person sprinklers wasn’t turned off public campaigns to inform homeowners about the harmful effects over watering are at the early stages and not widely used one of the biggest problems facing

Awareness is the harmful effects are not immediately seen by the homeowners themself although I was feeling the dis guy might be noticing there’s water bill many cities have tried clever marketing as catch basins and storm drains to remind residents about what happens to water and that fish and wildlife can be

Harmed the state of Oregon has put a lot of effort in repurposing stormwater and they encourage their cities to offer car wash tips for charity fundraisers these kits funnel so be in dirty water into a grassy area and not the drainage system so he’s like winston-salem North Carolina Clark County Nevada in Las

Vegas is and Stockton California dangerous a few are also producing PSAs on their websites and their local television channels reminding people about stormwater pollution photographs also do wonders many communities have taken to posting signs or displaying pictures of either pristine waterways and they should be or sometimes as they

Really are now the perception of storm water harvesting may seem a little like a literal drop in the bucket I know most people receive this as a rain barrel for Grandma to use in our garden but of course water harvesting irrigate trees is one of the intent of treatments and

Here in South Florida at fort Atlantic University my alma mater we collect rain water to irrigate these profits this is a new building on a daily campus and it estimates a 75 percent reduction landscaping irrigation now that it’s not just the savings for school but it’s

Also savings in the amount of water that is wasted in lawn irrigation of course cisterns have also been used for thousands of years today however they’re mainly used to just store water without repurposing and irrigation needs to become a priority when using systems I want to bring up another repurposing

Effort which is non potable water or a purple pipe dirty water that would otherwise be discharged into a water system can be reused for irrigation agriculture and recharging ground waters pipe systems are completely separate from potable water however at this time it’s not regulated by the ATA and there

Are still some concerns over nitrogen phosphorus levels that could leach into the ground florida and california currently leads away in the US with reclaimed water some of the examples here in Florida st. Petersburg for example can use reclaimed water to water over 10,000 residents along 60 schools

In about 100 parks Disney World users reclaimed water for cooling towers and washing vehicles and in 2011 Florida made the third week of May water reuse week all right transitional habitat is a place where two natural environments meet in our example it’s where water meets the land what this small area of

Additional plants can do to the environment in terms of wildlife water quality and aesthetic value is amazing for the cost these plants reduce unwanted algae approve appearance allow for animals to find shelter and of course filter harmful pollutants that would wind up in the lake duck weed is a

Common algae found in lakes where a transitional habitats don’t exist this algae can completely block out the Sun from the water killing off underwater plants and the all fish living in the lake here’s another typical example of what can happen when a transitional zone doesn’t exist all the property lets you

Have cuts or long leaving the clippings to blow into the canal these grasses take fertilizer and other harmful chemicals with them into link polluting the fish and the water alright it’s not a planning webinar if we don’t use big words phyto remediation is a fancy way of explaining how plants analogy use

Elements such as phosphorus nature and nitrogen which can kill fish to fit to their benefit just as we need trees to produce oxygen for us fish need these aquatic plants do the same for them it’s important to use native plants as exotics could also dominate the ecosystem aquatic plants are probably

Not what most people think about when discussing lamp Indian community but it’s becoming increasingly important to include them in a sustainable discussion in order to meet clean water standards algae is the foundation of many aquatic food chains and their abundance ultimately determines how many fish can survive I’m

Upon so despite what most would think algae is essential but high levels of nutrients such as phosphorus nitrogen can cause algae to explode especially in ponds lacking other aquatic plants or any other type of water current when they didn’t come to abundant severe oxygen problems result in death of fish

Immersed and submerged plants are critical to a well-structured pond or lake they not only provide protection for small fish and predators but also produce large numbers and vertebrates for small fish to eat plus they’re a great food source for many types of birds and just like us fish desire shade

You have the harsh of some rain some harsh sun rays water abilities and other showy flowers can only provide this for the fish these plants also absorb the toxic chemicals and of course aesthetically pleasing there are some slightly different definitions to the freshwater and saltwater patrol zone but

Since we’re referring only to fresh water in our conversation littoral zone is simply the area in which the land meets the water which in some situations there are shelf that’s the image on the slide above you here is an example of littoral shelf now this is a local park

And most lakes or ponds do not need this level of transitional zone but this serves a nice reference and shows our planted littoral zone can work here are two typical types of storm retention systems dry and wet both serve only one purpose which is to store storm water in

The conversation of repurposing storm water we need to begin discussing turning strong ponds into a multi-faceted area that can serve the community with more than just one purpose in fact recent research in Minnesota has shown that storm pond cannot just remain idle as years of use can compound toxic chemicals into the

Sentiment these chemicals are heavy and tend to sink in ponds where there is no current essentially years build up to make these ponds in efficient Minnesota is actually just realized that clean ups or storm bonds may actually cost up to a billion dollars here in Florida this day is

Taking some pre-emptive steps to help natural areas that could be the end user of storm systems by creating more strong ponds the throne plans that are going to be part of this program and actually do have a landscaping element in them so one of the solutions to stagnant or

Ponds is use of aquatic plants for phytoremediation now we get to use the word bioswales so bioswales is then mostly linear green space is usually adjacent to a roadway but the premise is exactly the same and it could be used for larger pond areas again by doing

This we are clean the water ultimate flowing into our natural areas increasing the lifespan of storm pond and possibly creating new habitats here’s a sign an informational sign it was posted outside or recently installed by Oh swell and this is great education to the public to show the reasons for

Why they did it well just provide a few websites that we use in today’s conversation that you might want to visit and learning about green infrastructure somethings we talked about today there is actually a green infrastructure foundation urban forest coalition is a part of is a and this is

A great resource if you are looking to for ideas on planting in an urban environment they also have a lot of great statistics on trees and their effect of urban environment lead of course we’re aware up I want to bring up again that you know lead has hundreds of

Credit points and a lot of them we talked about but some of them are really not used and the ones that I feel are not using me to discuss more do involve not just the green infrastructure but also landscaping finally shameless plug landscape inspectors Association in Florida our website is available to help

You here in Florida to learn about the process of grades and standards and has why resources here here for Florida in conclusion it’s important to remember what sustainability is it’s about ensuring that resources we have today will be available for tomorrow integration of different green spaces as

The quote says is going to be one of the tools that we need to use to make our community sustainable and it’s up to us to make sure that landscaping stays in that conversation of a sustainable community thank you and I will now turn it over to Christine wonderful Erik Lora

And Ted thank you let’s jump right into questions we have a host of them that I’ve been gathering throughout the presentation the first one is for Laura and could you talk a little bit more about what a clear zone is um seven foot clear distance seems pretty drastic that

Would prevent many if not most City trees I am not understanding what a clear zone is can you talk a little more about that um well the clear zone is really the room that the root need to grow at least in the foreseeable future and yes a lot of cities have a lot

Smaller and with you know whatever strip this is but the only way around and in a smaller environment is now doing human measures which include root barriers chemical root barrier either physical or chemical barriers or like I talked about with structural soils and tree wells that go underneath pavement that’s a lot

More money that’s why it’s not as popular but obviously it can be done there’s a lot of cities that have very small lack of better word landscape strips in the streets and that’s why they’re it’s more costly to do but when there is upfront planning the 7-foot minimum is really really what is

Required by any tree if it’s plants shrubs four feet minimum area I don’t know if they answer this question for you Christine that’s great thank you um can anyone speak about any experience or success with Silva cells for the underground part of a tree root system have you had any experience or successes

Look fil ba SI elle VA y el VA that sounds like a specific either trademark name or a company name so I mean Eric’s doing a quick search from the internet what hey Paul is it that is all like okay damn you actually I brought up a

Slide I don’t know if silver the brand name but I actually showed a slide of the underground of a tree a tree pit and you know most urban areas if you go out today you’ll see a tree great so see a tree will see a little bit of a metal

Container right around the tree sometimes hardly any room for that tree to grow and what we’ve learned from years of that is that the the tree roots you know they’re looking for air they’re looking for to breathe and so they want to move upwards and what happens is you

Know they’ll push up the sidewalks to push up the papers and things like that so these types of greats allow the roots to grow in sort of an intrinsic fashion and kind of remediate them want to drive upwards and pushing into the pushing to the sidewalk since the roads and that’s

Why they’re being used more often if not there they definitely should be used and before we get too far away we had a couple people type in about a clear zone the phrase clear zone is also sometimes used by highway engineers to describe an area adjacent roadway where trees and

Poles are prohibited as part of a misguided safety effort and then clear zone is also referred to as green strip or Parkway it refers to the landscape strip between the sidewalk and the curb in a street and yeah I guess this is Ted again um clear zone I mean I guess could

Be interchangeable in other areas with sight distance triangles what we use here that’s a a triangle if you will have a certain distance by a certain distance away from a public right away for example 30 feet by 30 feet and here at least well in the city its trees are

Allowed in that zone but not bushes shrubs doing a 3 feet and 8 feet but yes department of transportation sometimes require quote clear zones you know anywhere within a 150 feet of a nose of a landscape of an island it’s not now it’s not in landscape violence just

Basically a grass island so yes there’s a lot of deities that are making it illegal to have trees um and just now the the person who asked a question about Silva cells says that there are product that’s used in urban streetscapes to allow tree roots to grow under pavement and can also accommodate

Storm water storage you’re okay next question Laura talks about the commitment to chemical free wands Ted mentions using chemical applications for the pest management of trees the question asked would Laura provide some suggestions for Ted to consider to reduce the use of chemicals on trees so I guess the question more is

If we’re talking about commitments to reduce chemicals that can drain you know into our stormwater how do we talk about at the same time using pest management to to keep our trees well I guess I would start with the fact that you know we go back to using the the right tree

In the right place bye-bye planning sustainable landscapes or we’re going to have a lot fewer pest issues and need fewer chemicals so I start I would start with that did you want to add to that Ted yes actually it was misunderstood what I said was that we do not we want

To use natural processes and not chemical applications that that’s the opposite we want to do we want to use conserve by using beneficial insects and also natural quote pesticides but that’s that’s not quite well you know if it’s obviously the the reverse what we were talking about we definitely don’t want

That okay um are there any good case studies of communities which have eliminated leaf pickup that’s a great question I I’m not aware of any myself going through my California there’s a lot of leaf recycle programs during the fall in in at least Northern California where the Sacramento region there’s a

Lot of London paint plane trees sweet gums they drop their leaves in the fall that’s when there’s a extra push for a green waste program there’s also a frequent pick up of green waste in Sacramento I forget that how how often it was at least twice a month if not

Once a week you could have your green waste picked up at the curb in clear bag amin a flurry and i wasn’t aware the trees that leaves fall from trees traverse the northern thing you’re so funny ok I picked out of the room um ok this is a good question we’re working on

A new landscape regulation for our city one question we had was what kind of level of qualification should we require for those persons preparing our landscape plan well there’s a different levels of the qualification it depends on if the goal is later on for inspections I know Eric here is jumping

Up and down to push the landscape inspectors Association but the having some level of landscape architect experiences what we look for in my city as well as also have it being a certified arborist is very beneficial having some some type of green industry experience or qualifications would be

Key but people who are more hands-on are you know sigh planners who also worked very closely with you know landscape plans and other professional entities that I talked about even engineering companies and architects they they’re frequently overlapping so out of the ranking like that are breasts landscape architect and then maybe engineer and

Someone with landscape inspection experiences is very beneficial great this question is specifically for Laura and Laura I don’t know if you can pull your slides back up we can change the screen setting so that we can see our slides and can you explain why the water

Quality of the pond in the Florida slide example was so apparent from the aerial photo this was way back in the very beginning of your presentation um yeah it was pretty poor water quality let me see if I can pull this up here who are you if

You can pull it up i’ll change the screen presentation to you so that we can all see it okay i’m there okay actually it was a it was a four or five year old kid who first picked this out of this picture to say well look at that

House or look at this houses there’s no landscaping around it but basically this is a neighborhood that’s actually not too far from the Everglades in South Florida and you see there’s a lot of turf grass and possibly assumably I guess a lot of fertilizer being used on

The turf grass and nothing to really stop it so with that extra nitrogen added to the water we we see a lot of water quality issues so it’s not so much what the heart look like from the aerial it’s I guess the things that we don’t

See around the body of water that sort of tells us what the waterfall you might be it’s I mean you can see it’s kind of the murky green color it’s full of algae which has been stimulated by that that extra nitrogen that isn’t meant to be

There it’s just you know it’s not a low-level problem it’s something that’s you know that this photo was taken from a helicopter so it’s some when you can notice the the poor water quality from this far away it’s pretty bad if I can just try them for one moment what you

Notice about that is there’s no water current in that particular area it looks as if the water flow channels into this kind of a back lake and is nor else for it to go so the algae bloom is going to occur I did bring up transitional habitat and this is one of those

Examples in which transitional habitats and the use of aquatic plants could remediate them and if you notice above in the top of the slide is obviously a golf course you know unfortunately golf courses use a lot of fertilizers pesticides and other chemicals to keep the course on top condition and this is

One of things that we’re kind of are talking about and protect our waterways and keeping our waterways clean you know if there isn’t anything landscape lies landscape material in that water to try and eliminate those toxins then that was going to happen great thank you um just a few more

Questions this one is I guess just for the group is it better to have many small trees or fewer larger trees in the urban landscape well I I mean that’s very subjective Ted again I I’d prefer I mean here’s my opinion I prefer larger trees and less of them but South Florida

Were forced with a lot of overhead power lines so we have more mix of larger trees away from the power lines and parameters and smaller trees that are closer together maybe 20 feet on center instead of 25 30 feet on center for the large tree so I think the the trees that

Grow larger it not only aesthetically look better but those trees in itself do a lot more you know flood prevention and uptake of water and everything we’re talking about plus carbon sequestering with the larger tree canopy so and of course most areas native trees are larger in itself the other ones are more

Mid-level trees just acids to add on a little bit to that I would probably go at large trees myself it’s a quantity versus quality decision with larger trees you have the ability for more habitat for animals birds examples and your the ability for for them to utilize

That space you know native no matter what we do whether we’re making it as a native landscape or was just in front of our home nature is going to find it there and we want to try and make it possible for them to be able to survive

Great Laura were you going to say anything before we move on oh I was going to interject my my preference is to kind of maximize the canopy coverage as much as possible so if a big tree is going to fit and thrive that’s great but you know if the space is more

Appropriate for a small a tree I I’d go that route but the more canopy coverage while while you’re maintaining diversity of species is in my opinion ideal right um this is the age-old question I’m surprised it took this long to pop up as a question has there been an economic

Evaluation of sustainable landscape first cost of the traditional one well I’m glad you asked there has I mean it’s theirs in addition to real estate organizations trying to quantify that is difficult but there’s been national studies and organizations that don’t come to mind at this moment but I

Believe the is a website if someone wants to check that out there are links and one of those lynxes it’s going to be the economic benefits and there’s they have been quantified and values you know even like the eric has the urban forest coalition website so for example one of

Them quantified the number of pounds million pounds of tons of carbon sequestered per year in a large city like New York City and it’s billions upon billions of dollars and if you divide that by number of properties you know you get an individual poppy benefits so yes they’re planning studies

Out there to use yeah I did this plenty of studies unfortunately there are not theirs probably not the same the same way of creating the same study over and over again when a study is done a lot of times what we see is they divide a

Different formula to do the math and so a lot of times there isn’t that comparison but Washington DC actually just this year completed a study in intensive study and supposedly the information could be out you’re an extra and I led to that as well a smaller

Scott a study that’s taken place here on campus at the University of Florida on florida-friendly landscapes so for those of you who don’t know it’s our kind of our branding of sustainable environmentally friendly landscapes some of my colleagues are comparing the the time and costs associated with a a more

Traditional residence or landscape versus florida-friendly landscape and some of the preliminary data show that initially the time can actually be more attentive because your hand weeding that type of thing but then the water savings is has been just under half I believe or close to half for the the more

Environmentally friendly landscape so definitely fewer inputs over the long run great um we have time for one more question um so we want to know in one of the slides you you showed those fun gutters and we want to know where the fish shape storm grades are coming from

And how how the cost is compared to traditional gutters is this more of a public art installment connection or it you know is this solely through the regional stormwater you know where who does those and how expensive are they and where do we get them well they give you a simple of spray

Paint public works departments typically the ones who are doing that most of those photographs were from Oregon and Washington Ted did you want to get well I known for direct experience in Northern California a lot of the drainage districts have those that they’re actually their construction constructed for them so I’m sure there

Are companies who are used to making these and will be willing to ship them anywhere in the country from Portland Washington or California so just Google fish-shaped storm grates and see what comes up yeah well they’re there have lots of happy faces on there were many many more examples out there well I

Think this is a good time then to end our presentation so we have some food for thought for the rest of this weekend so Eric power and Laura Warner and Ted Kozak and the florida chapter of APA thank you for joining us today this was very informative and interesting and

Thanks everyone for joining us this afternoon and to all of those Miami Heat lovers I have to say go cavs as a clevelander and everyone have a great weekend we are I can’t believe you said that happy you must not have known I was from Cleveland painful alright everyone

Have a really great weekend and we’ll see you next time Thank You Christine bye-bye deluxe
