I’m going to turn the bar i’m sorry i’m going to introduce our speakers now here we go hi run pack is our first speaker as a professional aicp certified planner for over 25 years hiram has worked with municipalities the federal government usda regional planning agencies and private clients his focus has always

Been on the land and man’s optimal relation to it as Director of Planning in simsbury Hiram has worked extensively on consensus building processes recently these involved a community design charrette and adaption of a form-based code for simsbury town center he has been working with several firms and

Groups in many states and form based codes for over six years other recent efforts include drafting a planned area development regulation which was recently adopted in simsbury to peds have already produced a restored grist mill restaurant 88 apartments 20 townhouses and ms housing project and an urgent care facility in simsbury work on

Low impact development stormwater policies and regulations and workforce housing development zones were also recently adapted other current endeavors include significant mixed-use development specialty housing and transit related projects before coming to simsbury seven years ago Hiram owns the town planner in new canaan connecticut for seven years during this

Time the p OCD and zoning regulations were completely revised and many major projects including construction of Teen Center and the preservation of an important historic downtown theater and other town-owned historic buildings were accomplished Hiram was also the senior planner and then assistant town planner in Greenwich Connecticut for seven years

And did coastal application reviews and assisted with the update of the POC d previously had worked with the eight towns in the Southwestern regional planning agency region in Fairfield County when he worked for SW r PA and many environmental projects he has also worked for co ji cnv in Waterbury

Connecticut and environmental and transit programs before his service as a US Army officer Hiram attended Cornell University and the University of can he has taught science at the secondary level and geology at the college level he is also a consulting planner and a Connecticut license arborist he has also

Served on the board of selectmen and board of tax review in his hometown he is also a CNU member for the past few years in his spare time he enjoys showing his parson Russell terriers and bicycling although not at the same time our second speaker is Jonathan Ford

Dedicated to smart growth in New Urbanism led Jonathan forward to find more speak in design a new urbanist civil engineering consulting firm in 2006 Jonathan’s experience is diverse in addition to 15 years as a consulting civil engineer he is co-founder and past president of the New England chapter of

The Congress for nirobe anism a night fellow and community building at the University of Miami School of Architecture and on the faculty of the form based codes Institute Jonathan has been published and has lectured across the country on a range of topics including walkable neighborhood design density for watershed health and Smart

Growth infrastructure planning he is a licensed professional engineer in Massachusetts Rhode Island North Carolina and several other states John and his family live in walkable Providence Rhode Island okay I’m going to turn the presentation over now to Hiram alright Hiram are you there oh hello Hiram your participation okay there we

Go hmm okay start again yes please could you please speak up to thank you sure greetings thank you for attending this session this afternoon I appreciate your participation my presentation will present some background information and some context for the beyond li d work done by John Ford that more speaking

Design the work here in simsbury has been quite successful to date and we started on this and I go through a little bit through the process of how we got that got to that point but as many of you probably know blending higher density development especially in a

Small village in New England while assisting in cleaning up stormwater and at the same time is often difficult to do sometimes these ideas seem like they should fit together very easily and they’re often quite difficult to do a lot of the literature talks about what the density that is the impervious area

Should be in the watershed and sometimes you run into figures like ten percent and people talk about trying to make sure that the imperviousness is not exceeded one of the things that we are really striving to do here is to look specifically at the situation we have

Here in since Barry to try to indicate that we can in fact integrate green infrastructure into the planning process we started this process in about two thousand and nine we’re still working on it today but I’ll talk a little bit about how we got from the very beginning

When I first came to simsbury into where we are at its point in time just a little bit about the background in the context in simsbury in 2007 about a year after I got here we finished plan of conservation and development which in Connecticut is required to be done by

Municipalities every ten years one of the other documents that has been very helpful with regard to the planning process here in simsbury the guidelines for community design these guidelines are used by the design review board in the review of all the non residential projects that come into town and recently was updated

After extensive review specifically for the town center as you’ll hear more later on from John the simsbury stormwater design guidelines the articles that were presented and put together as part of that process and several of the test areas that were looked at are also key in developing

Downtown and other areas looking at el ID at the same time and finally we have the sense barycentre code that was developed in 2009 and 2010 and adopted in April of 2011 these documents essentially serve as a basic backdrop for the work that will talk about today

A little bit about simsbury centuries a small New England valley town typify by basalt ridges running north and south in the town a Talcott mountain ridge runs on the eastern side of town there is a significant change in topography from the west where it’s quite low to the

East side of town where it’s floodplain the east side of town drains to the north flowing farmington river it’s characterized by meanders and an extensive floodplain in the town center we’re also lucky in a way that the river actually meanders around the center of town provides a significant amount of

Open space that will show you on some of the graphics that I have later on here but does provide a large natural area in the center of town this is a photograph of town center pretty much as it is now showing that the high slopes on the west

The ridges drained toward the east and toward the Farmington River the road that you see running through the middle of the town essentially through the middle of the study area that we did for this Charette is root n so state highway Tulane state highway residents have been

Very specific that they would like to see it remain a two-lane state highway with this little modification as possible but this gives you a basic idea that the drainage from west to east important factor in looking at how we approach to el ID in simsbury just to

Give you an example of some of the structures that are in town and some of the sensitivities that we had to deal with during this process just like to show you that on the upper left is a starbucks that was an old house that was going to be torn down for retail

Activities the design review board was instrumental in making sure that that was not torn down and in fact does still served to this day as a really nice starbucks very busy place directly across the town hall the lower left is a small shopping center also in the same

Area and what I would like to bring people’s attention to is the arrow in the center of the rear of that photograph shows the ridge again on the eastern side of town that shows a significant delay in the topography the relief in the topography in the photograph on the far right just

Indicates what the Town Hall looks like again another historic structure so we had to make sure that anything that we came up with would match with these types of structures here in town again just a couple more structures that are in the center upper left hand corner is

A real estate office the upper right hand corner is a funeral home actually years ago was a home converted to a funeral home and has been there for many many years as well the town’s ten sensitivity to a green infrastructure is sort of portrayed by the small Park the

Small vest pocket park it’s called shills park in the center of town significant number of very nice specimen trees pervious walkways and significant landscaping Rick directly in the center of town one of the churches it’s in town again indicates that its wealth well landscaped note that the sycamore tree

There is part of our streets ka plan they’ve been around advocacy for many years and that is continued to be they’ve been replenished reestablished whenever they’ve broken our somehow been destroyed by storms there’s no new development plan for this particular site but it just provides good context for that particular area

Another town center historic home past influences again that the town is concerned about indicated by the fact that this was originally the homestead of the eno family famous for us transportation activities was the birthplace of Gifford Pinchot first director u.s. Forest Service and the homestead a firm out of Hartford did the

Original landscaping on this property landscaping has significantly changed over time and it’s not nearly as nice as it once was but the structure is still there and obviously historic structure town has a easement on the front lawn of this property to make sure that nothing inappropriate happens on this property

Another town center building and this one is a particular interest to us because it was originally a home in the 1900s obviously a fairly large home then it became a bank in an art gallery was recently sold when the bank decided to relocate to smaller headquarters but the

Future use of this building is particularly important because it is in the town center and because it is in the area that’s governed by the forum based code you can see that the typical street lamps that are located their town standards street lamps in this particular building will be very

Important going forward in our discussion the planning issues that the town was faced with during the period that I’ve been here from 2006 until when we actually did a town center Charette in 2009 were the fact that as you’ve seen I have number of historic structures have to deal with but the

Actual development in the town center was really quite slow there was nothing else going on there was no activity the retailers were complaining that there really wasn’t a lot of activity in town we wanted to see what we could do to spur on economic development there was a difficult land-use process there were

Many boards and commissions that people had to go through the fact that in Connecticut in this particular town anyway the Planning Commission is separate from the Zoning Commission is separate from the Conservation Commission which is also separate from the design review board and there are a number of other boards and commissions

That projects have to go through this may not be different from lots of places in New England but it certainly is different from lots of places in the country the difficulty of the review process was certainly putting a crimp on development not that all residents necessarily objected to that but when I

Came here initially I was under and understood that creating economic development in an appropriate context with the right texture was important to do just before I got here I was faced with a large format retailer that had proposed development in the south end of town and that particular development in

Addition to the big box had a number of other uses associated with it but the total development that area was about nine hundred thousand square feet what this development did was and it’s probably not a typical for many towns is it really sort of fractured the town

There were many people that thought that that development was far too large and should never be built here there are many other people that thought that the economic development was a good idea the idea was is to try to heal those fractures in the town development process at least the perception of it

And to make sure that people felt comfortable going forward about how development was done the town and to make sure it was done in a transparent fashion now the town is focused on a design and historical in keeping historical buildings and making sure that they’re appropriately used so that

In 2009 we did a full-blown town centre charrette there was a lot of discussion about what that activity should produce and basically it was decided that what it would produce would be a form-based code design review board thought that that was an interesting and appropriate way to proceed townspeople were

Uncertain about it but it was clear that what we needed to do in order to make sure that if we were going to produce significant density in the town center that we had to do that through public consensus that is just critical to the process that we use and it was very

Important this particular process design review board is a non-regulatory board and that it makes recommendations to all the other boards and commissions but it reviews all non-residential plans the development process ultimately was streamlined by the form based code in the town center and the Zoning Commission adopted a consent agenda

Process in 2011 that also has sped up the process whereby things can be approved that are actually of a smaller nature and actually up to about 25,000 square feet can be approved administrative ly that’s actually very unusual for that to happen in Connecticut why do we want to do with

Shrek why do we want to do what she read this photograph many of you have probably seen that before but it’s fairly typical of what the land use process looked like although the costumes may have changed somewhat and perhaps the actual firearms aren’t used anymore the actual difficulty in getting

Through the land use process in town was certainly something that many of the economic development people were very concerned about so what we did was we made sure that we started the process in a very public way we did lots of advertising lots of public TV lots of

Posters what’s early on the website lots of public announcements and then in 2009 opened up the building in the background here is the simsbury library to the public as you can see the hours for the charrette were 8am to 10pm those were actually fairly modest we probably were

There before that and probably there after that but for that whole period of time there was a significant amount of work going on to produce this particular code for the town center we had a full house we didn’t really know what to expect but as you can see from some of

These photos the room was packed there were probably in total over 600 people that attended these charrette sessions for a relatively small town like simsbury what’s the population of about 23,000 that was a tremendously gratifying to see as many people interested in the development turn out

As possible we tried to involve as many segments of the community as possible including Boy Scouts we tried to make sure that there were a number of opportunities for young people that participate in this process and made sure for example that they could in fact participate in the process on their own

And not be so ground out by lots of the older residents we can see that there are a number of people that attended for selectman is sitting there in the front row is very interested in what was happening as well and the attendance was not only good but was extremely

Productive as well the town itself has two main road that is a state road I mentioned before hot Meadows 3 which goes through the center of town right there you can see that there’s another Road that was constructed about 20 years ago 20 to 24 years ago actually called

Iron Horse Boulevard and that was constructed as a bypass road to relieve the Pratt traffic on the state road in the town center there’s a fairly narrow town center actually with a relatively small number of cross streets right now but one thing that’s really significant about it as i mentioned to before is

That in addition the fact that it’s significant all the stormwater drains from the hills to the west across town center to a large flood plain on the east this area was wisely purchased by the town number of years ago it’s about 400 acres and was known originally as a

Baker property it’s now known as simsbury meadows there are a number of things that are taking place in that area in addition to number of trails that are through that area and a wide variety of environmental activities through the area there’s also some development that’s on the edge of that

Area that we’ll take a closer look at later on as well so that was the outline of the study area that we use for the charrette you know in all reality all we did really for the charrette was look at the town center area between these two

Streets and the floodplain area in the open space area was not a direct part of the coding that involved a lot of time there was there were no structures proposed out there nor did anybody think there should be that is the area that there is currently a Construction Yard

On that site it seems like it would be not a wise thing to do in an area where there’s a flood plain that particular area there you sort of see that there’s a pad there elevated above the floodplain and you can get the idea that it is not directly

In the floodplain although you can see from some historic meanders that took place in that area that it goes very close to the Construction Yard that’s there today get some more closer pictures of that in just a second how do we fund this is usually a question that

People ask and we had very small amounts of existing funding but there was some existing funding in 2009 part of the that funding was directly from the town we also had a grant that was from the state with regard to incentive housing zone that is producing affordable

Housing in town each of these grants had specific requirements if you goes in just a second we also had a grant from the Connecticut trust restored preservation culture parks and tourism was a very big part of what the town was interested in and very interested and may the town remains an active tourism

Destination with town was recently named 12 12 distinctive destinations in first one and the only one to do that to gain that and we’re very proud of that as well Connecticut dep or now dep as it’s called produce also a small grant for us to make sure that what we did was in

Keeping with the water quality goals of the Farmington River that flows morphogen through the center of town what we ended up producing out of the incentive housing zone grant was a workforce housing opportunities own with a zoning regulation and along with design guidelines some historic preservation and we did redid the

Charette the work on the design guidelines that I mentioned a moment ago and as far as the this Dustin discussion today is the connecticut dep provided the funding for the l ID work and actually the beyond el ID work that John Ford did for us in the town center what

We hope to end up with is a set of documents that came out of the Charette that are complete and comprehensive and all those documents are found this reg in the regulating plan of the town center code question then becomes once we get got all this new density planned for if we

Have significant new density how are we going to deal with the storm water and not upset the new code they’re very difficult space is defined put storm water and many of the urban and even more densely developed suburban situation situations have difficult times finding places for that storm

Water to go how do we fit all the pieces together we were convinced that we needed to use el ID we needed to use light imprint as far as that applied as well and one of the things that I was particularly interested in was disconnecting the sources of where the

Storm water originated from the receiving water that is the Farmington River treating at the source whenever possible was important for us to consider and developing alternatives wherever they were needed was also critical for us this just simply runs down some of the things that we did with

Regard to how we got the money to do the charrette how we got it to do the form based code important in this list is included in the el ID work is part of the Charette process people were told from the beginning how this would work

And how it would fit into the whole process we also worked with the University of New Hampshire stormwater center and we actually conducted a workshop here in town for the town engineers in the area many of the town engineers in the smaller New England towns are very set in their ways and

That’s not necessarily a bad thing but the thing is that they’re not necessarily very comfortable with lots of things that li d talks about and so instead of using just dell ID they’ll also require some existing techniques to be used basins and pipes when they’re not necessarily necessary we wanted them

To understand what we were trying to do here and hopefully gain an appreciation for the el ID tactics and principles that we were employing here one example of what we did with the form based code and you may may like this or may not like this but the idea here is that

There’s some existing structures in town that were not necessarily structures that we’re going to be kept forever or that had a particularly redeeming historic value this is an existing office in some commercial space that’s on meadow street you may recall that I showed you that hot meadow street and

Iron Horse Boulevard run parallel to each other run bull so this particular structure is an office and commercial space as I said and one of the ideas that somebody came in with very quickly after the charrette was to develop this particular piece of property I show you

A little bit about what happened here if you look from the Iron Horse Boulevard side uphill to this property you can see that there’s almost a story difference in elevation this is viewing from Iron Horse Boulevard of slope to hop meadow Street take that same house and you can

See that that same house added to the right side of this particular structure was a relatively small part of what could be proposed as far as a new development was concerned this was just a conceptual sketch that was brought to the Commission after the code was adopted the Commission decided that if

In fact it did come back as an application was something that they could possibly favorably consider although no formal was decision no formal decision was made on it at that time because of the financing and the the personalities involved this particular project has not gone forward

Yet but it’s still in the wings and hopefully it’ll go forward sometime in the near future on the lower side I’ve mentioned that this was a through lot and the lower side on the Iron Horse side of this particular parcel there’s another structure and this again with a brand new structure where there’s

Nothing that exists right now and you may be able to see that on the lower level there’s parking underneath this building and you still have three and a half stories of structure above it so with a significant structure where there’s nothing right now but i’ll show

You in a moment as we get to the code it details in the code about how that all fits together this is a picture of the illustrative master plan that came out of the charrette itself this is the area the contracting yards as I mentioned we

Focus on in a few minutes this is where the town hall is located and the structures I just talked about during this right here you right here where hot metal street and the through lots down 200 horse Boulevard this is a the town center form based code it’s a street

Base code and they’re really only five zone associated with it FC one two three four and five obviously as you can see it’s a street based code and so those of you that are familiar with that realize that the street and the street frontages actually dictate many of the uses that

Are found in the code the only area that’s sc5 in this particular code is again this area here where the contractors your heart is located a significant amount of additional development is potentially able to be located there for a couple of reasons one is the fact that it is substantially

Lower than the rest of the town center so there’s a significant amount of additional height that’s possible there as well as the fact that it looks out over that significant floodplain that I mentioned before in the floodplain but it looks out over it the regulating plan is established and and while these may

Not be easily readable simply sets out the particular designations SC 1 SC two three four and five for the particular zones there are also some Civic sites which are set aside the Performing Arts Center and the open space that’s part of the floodplain in that area as well interpreting the regulating plan is

Another important part of the code again a street based code you see in this particular diagram here in the upper left that these dashed streets are their existing pathways of past throughs but they’re not actually technically municipal street to this time so they’re more alleys and they are anything else

So they’re indicated by dashed lines as opposed to the solid lines this street here which is wilcox treat the center of this diagram is a central retail street and the primary focus for creating additional retail on that street along with the historic structures that are shown here in black those are the

Structures they’re called keepers or structures to be preserved so that retail street actually focuses on is anchored by some of the historic structures on the front of Wilcox one of the thing that we did in the town center code was to make sure that the height restrictions were observed

There’s the Old Town Hall which is called you know Hall in the town center has a wonderful cupola on top of it and it’s a historic structure was built in about the 30s 1933 I believe and what we wanted to make sure was that no other buildings in that area were taller than

That structure so there’s a respect paid to the height of that structure and this height map was prepared in an effort to make sure that no structures within that yellow a boundary there and through here are any higher than II know all even the structures that are on the downslope are

Required to meet not higher than the roof the main roof on ena law so that was an important part of the getting the people to understand how height would be impacted in this particular structure as well an ESC one’s own typical this is a long hot meadow street basically bring

The structures to the street lot sizes are relatively small pitches on the roofs are dictated transparency the windows a typical form based code documentation in the SD 3 zone just skipping over the sc2 for the moment on station street this is a typical again type of development a fairly crude

Boxing boxing diagram but still basically the idea is bringing the structures to the street some additional height some additional density roof pitches are still controlled as our is transparency in the facade articulation but that is typical in the SC 3 zone in town and the second we’ll talk about a

Little bit more later on the sims cross site that is that the Construction Yard site you can see that there’s a significant amount of additional development that’s potential there is some significant density that’s there there’s an additional height that’s there that’s actually the only area in town where four stories can be allowed

In the town center and I think up to 56 feet so that provides a significant height advantage for that particular site a summary summary of the frontage requirements is also found in the code for all the various front Edge’s lots again are fairly small 5,000 square feet one thing that’s important

To note here is that there is open space involved on all light all the Lots in town typically it’s fifteen percent for most of them it gets higher in the Civic and the open space zones but basically there is open space involved so there’s room to put some of the stormwater plan

For some of the stormwater accommodations on each of the sites that we’re talking about this area that we’d like to focus on now is the sims cross site that i pointed out a moment ago and i just like to say that that particular area get more attention by john in just

A moment this is an aerial photograph of that area the you can see that the obviously it’s an active construction yard we’ve been very fortunate in that the person that operates that yard has constructed even though it’s close to the river a very clean operation make sure that nothing flows into the water

Bodies of the wells that are near that you can see also to to the left of the Construction Yard is a large open area and that’s the Performing Arts Center this is what the plan envisions for that area a significant amount of residential development a road that goes around it

Also places for people to park to either look at the open space or hike down through the open space but also significant residential development for the town center plans for this particular project are in fact underwear are three people that are looking at that now with competitive designs we

Think that the green infrastructure is a key component to this process we would like to build continue to build public acceptance by using consultants who actually get it to understand what our basic philosophies and policies are in town to integrate those solutions into the new form based code as has been done

With our li d work and integrate those policies into the plans and the regulatory framework in town we selected more speaking designed to do that work and I’m sure you’ll hear more from John about how we did that in just a few moments just another quick example of

Some of the development that could take place in the town center this is an existing intersection of Iron Horse Boulevard Wilcox street this is what it looks out on Iron Horse Boulevard we’re very serious about biking here in town one of the first biking friendly communities in the state

We have cheryl’s and many of their roads and a multi-purpose trail that’s even to the right of that road so that they type a bikers they want to fly through town can do that while the moms and the baby carriages and people the hell de lis

Folks that want to just walk and stroll at a leisurely pace can also do that as well same intersection with some development for the future what that might look like same intersection with a little bit more development in the future as well just keeping in mind that

This whole thing looks out over about 400 acres of open space very design actually very interesting during the charrette someone came up to one of us and asked could they put a deposit on this apartment up in this corner already very very glad to hear that type of

Recent reaction this is the type of area that it would look out on again this is the floodplain area that the town uses as a recreation area and about as they said about 400 acres of open space Performing Arts Center bandshell any given Saturday night during the summer

There may be anywhere from five to seven thousand people there listening to a concert simsbury portion of these goes green ways also what they look out on again this is up just another view of the Performing Arts Center where the simsbury Meadows plan we’re very serious about sustainability here in simsbury

And we try to keep that in mind with everything we do this is a very typical diagram of what sustainability likes is like obviously has social environmental and economic components to it in many people have talked about this concept and many of the meetings that we come to

It’s actually a lot different than some of the typical zoning meetings that you might run into but in fact what people do is they do talk about it you do think about it and so what they decided to do a while ago was to actually memorialize some of the sustainability into a

Concept that we have at the Performing Arts Center where we take a broad look at the world the social environmental and economic impacts of all our planning activities and this statute was recently put in place to commemorate that type of outlook thank you very much and I’m sure that

John will have lots more to add in terms of details whether I like do you work but thank you very much and am happy to answer any questions later on thank you load some Jonathan for thanks very much iron and thanks to you all for joining us on this Friday afternoon friday

Summer afternoon beautiful here in providence rhode island so especially to those of you in doing them joining us this afternoon and thanks for joining us for a few hours before jumping into the Finsbury specific work we get in simsbury stormwater module what I’d like to do is run through a quick less than

Five minutes history of stormwater management slide will hopefully advance there we go okay the five-minute history of thermal era man has been as an introduction to the cinders very Stormo hired my module conventional stormwater management what we’ve seen until the lab 10 or so years where stormwater runoff

Is fed via system of catch basin and pipes to the magical retention basin on the outskirts of civilization where stormwater runoff is dealt with magically never to be seen or heard from again and what we see here we’ve been following this is the pipe in pitt methodology what i call rate mitigation

Finished their backyard claret it’s not doing a whole lot for neighborhood health social connections economic value and I’m sorry John I’m sorry I would like to interrupt um II that we’re getting some notes from people that you’re fading in and out could you try to speak closer I don’t know if if

You’re on the phone or if you’re on speaker if you’re on speaker do you mind taking it off me hopefully that better keep me updated i’ll get the microphone or share enough right great that would be great thank you please PDF it will date them bigger so conventional stormwater management in

The recent past in relatively recent past evolving technical difficulty skirts too low impact development or li d and i’m guessing low on disk all are familiar to some extent with lig but very quickly led principles to reduce impervious cover to work around existing natural systems native vegetation natural areas and hydrologic pattern to

Utilize less common structural best management practices or bmps like rain garden disconnection amount of permeable pavement green rooms five well as a way to naturally filtered an insult rate storm water as close to where it falls as possible and create a multifunctional landscape where stormwater function can also double for aesthetics neighborhood improvement

Team that adopted more and more across the country and you can see that he’ll show a few new england examples but across the country where state stormwater design handbook guidelines and regulations are using lig as the core tenets of a stormwater management and site design approach de receitas massachusetts stormwater handbook on the

First page el ID we see this on the first page of rhode island normal our design manual which is brand new a fat December 2010 where oh I need a new way to handle stormwater the problem that we’re facing is that the LED technology and the Hawaii toolkit which is a huge

Advancement in stormwater management technology it’s still being applied to the same old land use patterns on the whole so we see here is the no family residential but every single lig bmt to think of apply from Vermont LED webpage we have here who’s fastest connection you have a rain barrel you have rain

Garden swale a permeable driveway preservation of the existent tree which is looking beautiful in the back and even a green roof here from Connecticut storm water quality manual a similar application or integration of the residential rain garden but in large lot residential examples world of looks like and practice here from New Hampshire

Stormwater manual the overlay of LED technology in the form of each of those red arrows representing the disconnection of down stuff for her via the internet but overlaid on the same old mini new spider has disconnected pelvis back dendritic tree pattern and a lack of the public realm ecological

Looking for associated with in your existing senators or proposed new challengers for a vibrant public realm that justifies to residential also retail if we’re talking about separation of when abuses showing here in the 2004 Connecticut some water quality manual where the model can accommodate flail overflow permeable parking for mature

Cavers even a transit stop and advice back and one of my favorite illustrations is showing the successive lig from Rhode Island 2010 manual being going for to public back to one as an example of conservation subdivision and I don’t need to be over the critical of lig the president is huge leap forward

Or from water management but when we’re talking about corn-based coast when we’re talking about density and being fitting within urban contacts and character l-ladies needs to be evolved because right now on the whole it’s a new one size fits all I’ll be involved one size fits all applications to the

Same affinities time so i showed my neighborhood in providence rhode island mrs. coolidge corner and Brooklyn Fort Smith New Hampshire two types of vibrant connected then places the complete Street active streets I value well low well visited on street parking so them to the street we’re not seeing integrations with stormwater management

Yet except for a few isolated examples here and there and God provided we talk about watershed health and manhattan and the same sentence but really this is an extreme example yes but we need to be talking about density when looking at a town a neighborhood a watershed density is the ultimate stormwater BNP

Having more development intensity and energy with less impervious area so really looking not as excited approach but at a overall approach of watershed approach per capita of purpose okay getting to him very how we did that in Finsbury detective places in high romanticism complete details what is envisioned it’s been very close to

Preserve existing sort of character and to add growth in the right place as expressed by the consensus division the density is pretty significant and what we’re seeing here is building closest to the street parking in the back a pretty high level of imperviousness but also a pretty high level low density bombing

And complete streets so what we needed to do was kill is firm water at first and we did we did this remodel work the whole town but the focus on the town center and understand how density worked for so the division in the form based code and how very extensive in the form

Based so might respond differently stormwater management and effective I’m so very quickly to written extensively about this online you can go to my blog or there’s an article on climate event led 2.0 is what I’m following is moving past l.i.e and I shouldn’t say moving

Past el ID but using a foundation at OID building on it so to speak to incorporate the connection for land use 10 and growth over time and also to important incorporate greater flexibility to design and content so I’m not going to all about all talk of all these pieces especially given my first

Time but the focus of the focus in fifth grade was really on number one steers and number four not all in for this area is equal in other words integration with land use pattern and density and number for designing the context or have integrated Hawaii typically the black street building and neighborhood

Scales to various entrance the work itself the stormwater module within three pieces to stormwater article this would be the ordinance but can fight regulatory language is like into zoning space planning and design criteria checklist which I’ll go through in detail but that’s a requirement for project for applicants ago at that

Checklist part of the stormwater article and the stormwater design guidelines which were an expanded documents to show the how and the why he’s more innovative guidelines and regulations using abuse at site specifically within sensory function all the work really was in support of the 2007 plantation with elements but looking at it review

Slightly different lenses protecting natural resources preserving and enhancing community character be utilizing typical la in folds and then thinking a little bit differently using a watershed a neighborhood approached to say contact development commute strategy to reduce impervious area in the watershed to establish these watersheds sensitive planning to plan criteria at

The neighborhood block street and site scales of development not just the site website approach and to define standards for incorporation of lig Bianchi’s that are appropriate for and use contact site conditions so starting with sofa for new standards of the ordinance the regulatory work I’m going to go into

Detail on the planning and safe design criteria checklist first got a little bit of a storm water quality and funding requirements specific performance standards and I big dipper’s four zones within the town center I’m going to talk about design and construction requirements the intent of the planning design

Criteria cyclist was to incorporate and infuse LED and context-sensitive led into the planning and design of all projects so this is required for all projects and i’ll show the tenth of the ways that applicants can respond to the beach criteria from scale but some of the highlights were requiring an

Enhanced existing condition plan to fingerprint the existing conditions to a greater level of detail to plan around and vic natural conditions limitation on ornamental on the included green street design guidelines which were very important if a tire and went through some of the conditions within the past pleasure where there are some informal

Ways that certain kind of evaluate now 14 in the future of streets because potential for very serious retrofit opportunity very permeable parking requirements for last in excess of 10 spaces and the discussion about special detention area where flight controls can happen in the right place and i’ll talk

About that and also design the right way so that the potential for multi function broken pieces such as part of the plaza parking lot fields etc with in contact and walkable zone and i’ll talk about these things very center flatterfit planning and design framework so show

You a few examples of the checklist and if you look to the right of the page the responses are these are verified technically infeasible or not applicable so we want these considerations needs criteria to be incorporated into the painting this is what the town is looking for but we understand and wanted

To be sure to plan a flexibility into the process because we understand a lot of you can enjoy the regulation and doing design guidelines sort of town Cole 10 meses but not every project every single criteria applicable within their borders bc is broken into watershed neighborhood Green Street for

Example a skiing at the bottom one one example criteria is surf air and driveway pavement with are the minimum required to accommodate public safety and emergency access so we can achieve traffic on there with enter the town center while also minimizing the verbiage area which would be a

Significant impact but it may be that is not applicable for a project moving on to a more detailed site design criteria for example 4.2 infiltration TMP and they’re located in areas of well-drained soil that may be technically infeasible you to budge or maybe the soils aren’t well draining but we want this checklist

To be filled out submitted so the town has a starting point the parking design requirement VIP design requirements and maintenance requirements and the requirements what I really mean is credit area and that there is some flexibility part of the criteria includes for projects with an inventor an analysis of power projects within the

Simsbury center watershed planning and design framework what we did here was apply environmental conditions and constraining has an overlay to the things very fender regulating plan to show how urban conditions urban intensity and different development patterns in the metal bowl jonim it with soil conditions photography especially

In pleasant and not surprisingly as many doings in town are so the town center is really already in the perfect spot in a lot of ways it’s just outside to four moons and seems very mention the foot plenty sandberg meadow is just east and down gradient and most of the quarterly

Draining soil were just outside so where where significant growth is envisioned so what we wanted to show was 44 different forgiving intensity have from water we handled and we had well draining soil is pretty much throughout the town center on the whole we should encourage infiltrations the maximum

Extent possible we also show and you see those asterisk what might see potential storm water receiving zone so hiring fly during those public is not fitting together this is exactly where it comes in the form of code showing additional period of time not necessarily being able to accommodate advanced

Requirements for storm water flood control especially you always want to try to see water quality requirements met exposed on sites possible but if there’s additional flood control to happen instead of having a detention basin for a costly underground attention on urban site or in urban infill site significant constraints can we work to

Locate those on the edge of the neighborhood where they can be efficiently built in the right place and hopefully with the right design it for for a shared neighborhood solution and that’s the benefit of using the forum page code integrated with stormwater is to get those shared solutions in the

Right place combining the environmental constraints and conditions with the future vision for what this place will be so recruited from discussion about how has it been sown might handle stormwater differently based on their urban intensity and context all hi infiltrations capability so we’re really encouraging implication on site where

Possible wanting thing to point out is a good example of an application for 15 fits all oid methodologies to a place like ten percenter it may be that a mixed-use retail street over greening to the concerns i’m going to be possible maybe not necessarily in tim ferry but in some places where i

Work that don’t want to have a ten-foot-wide bioretention spell between armed street parking and their retail visibility with the very professional Gail so maybe it has some zone you just get back a bit or I’d wage for those shared solution to work as a win-win I’m

Going to duty is a little bit we talked a little bit about open space and potential stormwater receiving zone locating these in the right place and using some precedent show how different types of open space active passive open states could also accommodate stormwater management from a pocket park to a

Larger neighborhood park playing fields and other types of oakland city we really want to encourage the right neighborhood solutions in the right place okay storm water quality and quantity requirements we had requirement in the zoning language for redevelopment per site that has over into city percent including impervious area to have

Alternative requirements to encourage the development and we usually dissipative structure and what everybody want to highlight associate this time it’s moved into one of the keys of the work which was alternative performance standard requirements for keep weight recharge volume and water quality within designated compact lockable places with

In town so far as we were focusing on the town center here is the underlying the off-site mitigation with storm water mitigation banks which i want to mention was very much encouraged by the town at the way if you look at the town center the watershed plan the stormwater

Insurance solutions are going to happen to town as a mechanism to both encourage and we hope facilitate some of that in shared solutions whether it’s staying in phosphate mitigation to happen for the plant or or providing the shared solution by getting back to alternative requirement for rave on water quality in

Walkable places this really is where we got to the intersection between form-based serve and density for watershed health where did to get a few years ago for the EPA comparative infrastructure analysis of smart growth on the top versus various methods building out that same road using a more conventional separated and trauma and

Land exciting to look at a number of various alternatives DK at the time one of the crew versus the large home builders dead cosplay is in their best interest to build smart growth because the day infrastructure last class we looked at really a can of worms in terms

Of the number of variables involved but in looking at side by side scenarios we’re able to come with as they relate to infrastructure five and what Morris tegan dying design has done since to build on that relationship being courteous area and infrastructure five and I should mention pipeline infrastructure prize as well as

Maintenance of infrastructures over time for significantly reduced for the GNP traditional neighborhood development scenarios compared to the PSD or more conventional suburban development scenarios so to build on that and look at watershed to the more pavement more rooftops we have the more infrastructure the more land or eating up obviously

Would cost more the bills but also results in more impervious area forgiven instruments which is belting so for example if you look at total phosphorous bottomless trap and those are three comparisons with different apples to apples development build us very cid on the left PSD on the right that the T&E

Scenarios by virtue cure lee of land use pattern and density outperform the conventional scenarios by far even even more so than what you typically see from some of the latest and greatest led zep management so here we’re showing that he and he man you having outperforming lig p.m. te

Technology that’s the first density the ultimate storm water management water should help be empty and then we’re integrating the latest degraded BMP technology and solutions on top of that when temporary this is a graph showing of density increases the annual runoff volume decreases per capita for residential unit basis so we looked at

The Construction Yard site eps bottom in yellow and we said well okay to do so filled out service and free center pose what would that painful that look like in terms of impervious area and watershed impact if it were built out / to zoning on the book and you can do

That graphically so the impact is significant if we look at in fergus area we can run up on the city centre approach product according conventional mitchell wears a lot zoning and what’s important about this i think this would be intuitive knowing what we know about development footprint and conservation

Planning practices etc but can we parlay it into the zoning for to help incentivize and enable grow in the right place so if we say that we can provide incentives for them located within an app center in cheap rate recharge going and civil ever form to zoning that’s on

A book you see at the bottom finsbury center with incentives cutting recharge volume requirements still outperforming the typical zoning so the two keywords stairs to meet you think about it differently through different lenses sorry incentivizing re-enabling both really work because the vision has been set and a foreign-based code for simsbury center

That’s adopted so we want to be sure that we can use this as one one way of enabling that density enabling boat conditions in the net default frontages party in the right place and density business along with from water banking and off-site mitigation get some redundancies help yet growth in the

Right place we use of existing infrastructure and really a watershed based approach to the foreign-based some encode we had said PMP incentive credits for projects within said immediate contact walkable areas since precentor primary among them and i’m in the interest of time going to move along a

Little bit to get to the design guideline when it comes to planning firm water management exciting designs context sisters the contest and visions in the code we wanted to be sure that our PMT to Li Jie’s EMTs are appropriate to that context so we looked at different types of water quality be

Emptied from a rural swale to residential streets maybe a mixed-use or more urban conditions will become harder edged more defining linear position and three blocks up where you see on the bottom right we can look at that approach to contact based approach to BMP clicking a permeable pavements for

Example from rural emergency access applications to more urban permeable concrete pavers with a few minutes even looking at permeable on-street parking within different conditions from grass maybe some packs of stone taters stone dust and then come up with a cable and a lot of you will probably recognize with

The pros from the light inference urbanism the first for dmca are calibrated to crumble you see the town center zones listed across the top other zones on the right the dark shading is where the empties are encouraged to min those own the light shading and brother allowed and

The white area they’re not allowed without sound engineer approval so stormwater design guidelines were separate companion document to the term order article and checklist where we went into some detail and you specific test site to establish why convey how it was thinking this way and have to meet

Specific design criteria using you to test site within simply Thunder itself so you recognize distance shop on site again a construction guard located to the east of the town center we envisioned we envisioned and allows you to plan within the guidelines of the regulating plan so within the area

Itself we redesigned the sound echoes illustrative plan work product to use the principles that we have put forth in the article and in the design criteria showing how specifically on this site we’d walk work around existing natural conditions which there wasn’t a lot on the site that there is some and how you

See on the left of the design those are stormwater repeating zones for up when center stone where that could be the remote receding don’t match in the right place where pocket part and green street and work to enhance the public realm while also providing potentially shared solutions for blacks development and

Happy mps you’re celebrating with a specific context regina bottom right on angel and criteria how we might see that playing out for this specific design and there’s some commentary within the design guidelines themselves reach criteria for the specific website and we have these drawings by Russell questions you’ve been incredibly founded

Developers architects in Illustrator you do need exact block from what we are looking at show topography to show how to BNP design and layout of the place designed with works using it seems very appropriate architectures as well so so for example this block which is moving towards us one of the common design

Challenges actually translating and electric appliance to a more specific tuning in to the next level and getting it design and build the defenders on a face becomes a bit challenging when the setbacks are reduced 40 and you’re still requiring one hundred percent water quality or flood control

Arms citing when you don’t have that setback of punish and having a fairly dense tree wall condition where the side yard setback overused as well you know but pretty consistent street frontage hear that from whatever not coming off the building to the door down gradient becomes challenging to find a place to

Deal with that but the very detailed say design consideration the one that becomes a challenge when integrating micro-organism informed eight toes with more advanced stormwater with plans we wanted to provide flexibility so you could have flow through planters within a very limited fundage on condition you

Could this is a perfect example where in the form of standard requirement to help enable this block rebuilt as envisioned and there’s also the potential for the off-site mitigation to happen so we call we also fold a lot of what we’ve been hearing and what I’ve been hearing in

All areas where I’m working is that we might not be seeing a neighborhood built in the next five years wind up be seeing a black belt in the next five years VRC and we want to be sure to accommodate is smaller-scale incremental growth on the level even of the site and what that

Would look like within a plan like simply centers wherever you have today a 40 x 80 wow that looks like this it can fill the comedy storm water infiltration and water quality on site without having you have a detention basin somewhere so we have a closed group plungers front

Yard we have so through cleanser in the back which may or may not have line is that overflows to albanian garden that would accommodate to stop runoff flows from the yellow building and then in overflow to deliver your alley to show that we can get some water function on

The flat not just without compromising the urban conditions for buying also to camping it we hope and we work with a lot of invisible of how those requirements workers conjunction with the impetus so I ask unanimous of time I’m going to there are two more tests legs this one was much more mixed-use

Retail black with parking to the interior it showed one of the things i want to show here and one of the common impediments to li be in a town center environment is austin State setbacks infiltrations requirements where if you’re required to set that 25 or 50 feet from a building foundation for an

Infiltration BMP that might work fine on a big box retail but it really eliminates a lot of possibilities with a block like this so if we’re going to do from people parking spaces for example having them in the right place would be 10 feet away from a building aviation

And also designed with the photography event run on some standards of human achievement on to the permeable pavement just plugging especially would not be came these are some of the conditions that we wanted to school or and understand how it could ship work and we did the same thing for another site it

Was much more redevelopment and in philology a lot more photography and a less thing i want to show is an evolution of what I protected earlier conservation subdivision la plan going from two-fold effect one we can think about an evolution of li ye both in terms of how it functions

Environmentally function from up all the expanse point and how it commits into an existing neighborhood where we were increasingly seeing in the rain going when I think across the country cottage court as an alternative for you to get density you can get it buildings fronting on common spaces that can also

Serve for stormwater management this is a project to build nice granite rhode island cells cottages on green 15 together cottages on three quarters of a nature but how i need s managing practices including 12 environments importantly to say Mabel parking to enhance to compensate cousin alternatives so they’ll I need to point

Out applications or positions as well so with that I’ll hand it back Christine again thanks for your time and look forward to questions great Thank You Hiram and thank you John we do have a few questions and again if anyone else has any questions we have about 15

Minutes left you can go ahead and enter those into the question chat box to the right of your screen this first question is for Hiram Hiram you showed a regulating plan with dashed lines for through ways that are not full public streets in this case to those dashed

Lines represent public right of ways if not if they are private property how is development regulated along them must development front them or could future development cross the dashed lines interesting question great question one of the dashed lines actually goes right through some private property during the Charette process we thought that that

Property owner might well be very terested to say the least in the fact that we had put a alley way through the property in fact the plan was so well received that there was no pushback negative pushback from it so that was one on private property a couple of the

Others are on public property although they’re really not well maintained full municipal roadways at this time so it’s a combination of private property and public property we think that they’re all realistic I think there was only one in the whole plan that received any pushback and that ran through church

Property and the church decided that that they were not ready in fact to do that and so we eliminated that from the final plan but but other than that it worked out very well so I’m not sure if that completely answers a question not but I’m happy to address it more fully

If you want to email me please feel free to do that great thank you the next question is for John what was the amount of sins simsbury contract with more speakin the amount that’s an interesting question I think you saw a grant it was the town secure from the state in the

The name of li e so I don’t think I want to throw the number out there it was not extensive but it didn’t allow us to do the stormwater article and also the design guidelines because it was very important to have both and really able to check Boris’s with into that account

To ensure that foreign language was concise as possible but it wasn’t out there in a vacuum that it was clear and backed up with design guidelines so I think it’s a question of scope and fee and I would very much encouraged I mean I do II having this work integrated with

Form based design preparation in the first place but to ensure that work is integrated both of the final end products encourages growth in a clear and it’s consistent great thank you and stay on the line because this next question is for you too are you recommending the residential

Roof runoff from gutters and downspouts should not be connected to the storm sewer system if so will this increase basement flooding our city’s property maintenance code requires gutters and downspouts to tie into the storm sewer system that’s a great question and that’s when we’re dealing with you’re in

My neighborhood in providence i think it’s a it’s a pen answer we certainly do in theory want to encourage this connection of roof cosmonauts and pavement and courteous area so it can fill bitter so we can slow down the runoff rates and get it into the ground

To wear at all as possible that’s the starting point from an environmental perspective it depends if we’re working in areas where we’re talking about retrofit where whether you have patients or not go to the conditions of waterproofing if it’s near development of their basement or not and what are

The setbacks from those foundation so that all really can be put together into a better kisser but what can happen with this connection up here in our neighborhood we’re working hard to push forward some retrofits debris dealing with very very significant both from environmental impact and financial implications consequences of the end of

Pipe so if we can get those fish connections of down stuff through the neighborhood to step in need to talk about retrofit pin garden ethic of thing but the study was done in the next neighborhood over that just look at that and show that there needed to be some

Caution in that neighborhood is accessible 100 year old homes as well as density their remaining it isn’t perfect solution there so as always and contact I do think a lot of state regulations guideline musical guidelines can tend to be overly conservative and one size fits all I know that’s not a specific answers

But we do want to encourage that infiltrations flowing down about right Nick thank you umm hiram is the simsbury stormwater design guidelines available online yes they are actually on our website town website which is shown on the contact information page at jons put up they are

There and if you have trouble getting to them just email me and I will make sure that I get them to you if you like that okay this next question is for either one of you how has the development community responded to the additional costs associated with the higher density

And BMP requirements of low impact development what about the general public that typically hear high density and automatically assume more traffic and congestion I can bike I thought I can talk a little bit about the the simsbury reaction one of the things I mentioned in the beginning of my

Presentation was that it was our desire to build a strong public consensus for this program from the outset and that came from the fact that as I mentioned earlier to that there was a nine hundred thousand square foot development that did receive no public input before it

Became an application and it was it was a bloody summer frankly that that’s not the way to do it the way the community responded to our approach are transparent approach in creating the code and creating the density was phenomenal I can tell you that as I said over 600 people attended the Charette

The final presentation for that that program was about an hour and a well is actually an hour and 45 minutes nobody left the room I can also tell you that the Zoning Commission unanimously adopted the form based code there were almost no comments in opposition to it

And it’s experienced a very very good reception when I explain it to developers at least in Connecticut about how we how the development process works here now they’re just stunned at how significantly improved it is over the former process we think that we can save money in time and obviously that’s very

Important in their bottom line two so we’re very impressed with how it’s worked out so far John may have had other experiences as well but that’s been our experience here locally well yes I’m speaking specifically hell ID I one of the things I always try to do

With my projects whether they be zoning or neighborhood planning or getting construction documents together is to show how lig approach to creating value and cost less because I almost without exception it really can achieve both those exist objectives so I utilizing stormwater infrastructure to provide aesthetic function so to help increase

The quality of place within a project and also increasingly the market is getting this stuff you look at the market is looking for a downtown cottage course for example so that they can walk to get a cup of coffee or gallon milk the green infrastructure beautiful green infrastructure resonates with that

Market so in a complex in comparison to typical more highly engineered stormwater infrastructure so really to get outside of preaching to the choir we believe it’s the right thing you do environmentally we also believe and can we can show and demonstrate not as part

Of the work we did to the EPA it does not flat and provide more value great thank you um this next one is for John to I have not seen any heavy vehicles on these roads can old-fashioned brick roads be used instead of asphalt these are low speed bike friendly roads the

Cobblestone ride would also calm traffic besides improved storm water quality I think on contact what I physically do is did brick is one solution I’ll typically have four trucks routes for highly trafficked highly traveled ways probably not too permeable surfaces on those routes well typically especially to provide flexibility for kind of

Skittish applicants designers and sound engineers to start with parking spaces street on street parallel parking spaces overflow parts we have the requirements for these designing requirements for / + / 10 basis to require those pages to be permeable and I think bricks are cobbled travel waves can be a solution if

They’re properly designing the right sub days conditions and giving us to traffic flows over again that is not a specific answer and it’s really as possible but the what I push for the design engineer might be a little bit different from if I were working in establishing design

Guidelines and turn whatever an inch requirement pretty much Valley okay I’m could either of you discuss methods of maintaining the long-term performance of permeable pavements I’m sorry Christine virtually the last bar that question again oh sure I’m sorry could either of you please discuss methods of maintaining the long-term performance of

Permeable pavements I could address that a little bit perhaps John I’m sure has something that as well one of the projects that we were fortunate enough to get almost immediately was a small market that repaved half of its driveway in response to our permeable paving request and they did so willingly just

Before a huge storm last October you know what they found was that it performed not only extremely well because half the parking lot that was done with permeable paving did really well during the storm the other half did not we talked to them about maintenance and I’ve talked to a number of people

Around the country about this as well all the parking lots are going to require some sort of maintenance anyway and so whether it’s sweeping as has been done in the past or whether it’s vacuuming as probably it should be done with permeable paving there’s still a maintenance cost to it there’s no doubt

About that but it needs to be maintained no matter what and as long as they’re maintained properly they should perform well for the long term one other example I can give you is it we had a large market that was recently approved and we had the conventional paving actually in

The area of the driveway where large trucks would would be going and permeable paving is proposed for the area where normal passenger car vehicles are as well we told them the same thing that normal maintenance is it is to be expected and probably vacuuming as opposed to sweeping would certainly be

Preferable there’s no no question about that yeah Herron following up on that this is really a topic in a self and came up quite often as we were putting this so ID work together I think it’s important to understand that natives requirement for stormwater in the structure just like paving

Infrastructure are always converted so any storm water management bien PA requires maintenance so it the expectation that you could put permeable pavement or a rain garden in and we it for 10 years for 20 years because it’s dell ID is not the case does require maintenance but to understand

How that maintenance is often easier for li e for example a rain garden by our attention it’s easily seen it can be done by a landscape and crew as opposed to other different types of utilities and it’s lovable so it’s permeable pavement is replacing some other type of stormwater infrastructure that might

Have been required like a storm sector infiltrator interceptor I should say or an underground systems all requires maintenance so we wanted to put into the design guidelines in the ordinance some level of comfort with that we included a lot of information about how to maintain permeable pavement how it performs

Becoming in the winter the design criteria requires and if you put permeable pavement and you got to put a sign as well because we get this stuff installed and once the designer and builder leaves the typical say a condo development or some other type of owner operators might just either unknowingly

Or will willingly ignore the differences for that type of BMP but it is at the mpu does require maintenance we also included operation and maintenance plan to be required again speed for your development so that that is on the book as well as the discussion of caen annual

Maintenance filing with the town to show these are getting maintained i should add very quickly that some of the research institutions you could look up some of the world works at UNH stormwater center is done where they’re trying to get permeable pavements of fail so leave it for five years plus and

Then see how performance and it’s still work even if its standards which it shouldn’t be it still works so infiltrate which recoverable can be vacuumed so I think you summarize the more this build the easier it will be and the more you’ll be able to point to projects within your community where

We’ve done and so can see that it works the one that I remote Mecca and I think that will help more than anything great thank you well it is 230 so we must close shop we do have a bank of questions that we were unable to answer so folks please do extend those

Questions to our speakers I’m just going to change the presentation back over to me for a quick moment just to do some housekeeping things perfect just some reminders that for those that are still in attendance don’t forget again to log your CM credits for attending today’s webcast and it is available for 1.5

Credits also I had a lot of questions we are recording today’s webcast and you can see it live by going to youtube and searching planning webcast or you can simply email me if you just want a PDF of it and you can email me at the email

Address shown on the screen which is planning webcast at yahoo com so thank you to our two presenters today John and Hiram and thank you to the Connecticut chapter for hosting this and to all of our participating divisions and chapters for making this webcast series available free and everyone have a great afternoon

Happy weekend but by everybody thank you bye-bye
