outreach meeting number one um just so that uh we do a few housekeeping things we are going to go ahead and record the meeting today and we'll make sure that that's available there may be others that were possibly not able to participate or if you've got others possibly on your staff that you like i hope you go for about two hours morning but we have a lot of information that we want to share and just make sure that we give engineers and developers and interested parties the opportunity for some questions and answers today um i know that we have a little over 60 people were on call this morning i see that we have councilman mcatee with this so welcome councilman mcatee i did not see that we had any other council at least at the moment that it's possible that we will have some additional city council members present we have several staff that are online from the city of oklahoma city that will be able to introduce themselves as we start this morning we also have two key consultants with us this morning we have brian mitchell smith roberts ball fire we have tim johnson with johnson and associates the city of oklahoma city engaged uh both of these firms to assist the drafting of the documents this morning so i appreciate that they're both online and available for questions this morning as well too so with that um debbie miller and very lodge with public works are going to help lead our discussion i want to make sure that everybody knows that we have the documents available online at okc.gov if you follow the links to public works you can download a copy of the draft drainage coordinates the also the drainage criteria manual is online and then we'll put the powerpoint slides which hopefully you can see now on and we'll kind of use that as a guide this morning as we walk through so is everybody good [Music] all right all right thank you daddy and this is debbie miller um [Music] the introductions um meeting protocol we wanted to go ahead and put some housekeeping rules in please mute your microphone uh use chat to ask any questions or raise your hand and we'll call on you after the presentation and try to answer any questions you may have and the documents like eric said found at okc.gov public works you can find the drainage ordinance which is chapter 16 of the municipal code criteria manual and we put together a summary of proposed revisions between the existing ordinance and what the new ordinance includes the agenda for today's meeting we're going to discuss and go over the drainage ordinance revisions and it the chapter 16 revisions include the definition updates and we were cleaning up inconsistency and inconsistencies and we're going to discuss the drainage criteria manual which is something new oh you went mute oh i thought it was just me keith yeah i'm not able to hear anything either yeah oh debbie so did you not hear anything i said we we're here and then then we lost you you went near me slide number two oh it's line number two okay well let me go back and i will start over okay i'm really glad you guys are all here and i apologize for the mute i don't know how that happened um meeting protocol housekeeping rules uh please mute your microphone you can use chat to ask any questions or raise your hand and we'll call on you um as eric had said documents are found at okc.gov public works you will be able to find the draft drainage ordinance chapter 16 the new drainage criteria manual and a summary of proposed revisions that we put these together so you can kind of see what the changes are between the existing ordinance and what we're proposing [Music] the agenda for today we're going to discuss the revisions we're making to chapter 16. um part of that is definition update and cleanup of inconsistencies and we're also going to talk about the new drainage criteria manual and like i said previously i'm really excited that we get to bring this to you this has been a lot of hard work that staff and our consultants have worked on and i'm anxious to hear what you guys think [Music] okay a little history and this was interesting i didn't realize this that the drainage ordinance was put into the code in 1970 as chapter 15a and it was the drainage and flood control ordinance um since then we've had 15 revisions approved by council since 1981 updating the ordinance um we do have periodic updates every time fema has a map mapping update on their maps and so those are also included in the ordinance and we have those two um the need for the revisions we need to address the inconsistencies within chapter 16. um we wanted to revise the definitions to be more consistent with fema um we wanted to remove the actual design criteria out of the ordinance and make it more of a regulatory document so that's where the drainage criteria manual comes in and revise the drainage design criteria to address the current future and flooding issues we every time it rains we get complaints and so a lot of the updates are to help address those i'm going to turn this over to very lodge and michelle is on the line too and they're going to go through he's going to go through the changes and what's included there you go barry all right well this is barry lodge with the public works department city of oklahoma city to go through the major changes that uh we're making to the drainage ordinance and and what's being added into the drainage criteria manual uh i'll go through all of these when we get to the end we'll open it up for some questions but so just for a continuity sake uh wait until we get to the end for your questions you can raise your hand and then we'll open it up michelle as i'm going through this stuff if you have if you have something you want to interject uh jump right in i'll try not to belabor too many of the points uh the slide that's up there now shows kind of the major items that are being changed that we're addressing detention open drainage channels our drainage criteria manual changes to the storm sewer system design public versus private storm tour systems that that will be kind of a big change to it and then we're making some revisions to our requirements on the floodplain activity permits so starting with detention this is uh something that we've been looking at uh all of the consultants that have been doing design in the city of oklahoma city for any length of time at all well you'll understand that currently our requirement is for uh detention for the 100-year storm only uh so one of the things that we are doing in this is that we're going to the a multi-frequency outlet design i'm starting from the bottom of the slide hope that doesn't mess anybody up so we're going to start requiring the outlet structures to be designed for the two through the hundred year events instead of just the 100 year event another change that we're going to make previously we had a an allowance in the ordinance for a fee in lieu of detention based just based on certain criteria we are taking out the uh allowance or requirement for the fee and live detention and we're substituting that in its place to where we will have a waiver of the detention requirement that will be possible a couple of circumstances where the waiver would be considered would be if your site drains directly to a public street or a public storm sewer that would be considered if your site drains directly to a creek or riven river channel then it would be considered an area where we would not give consideration to the the waiver for the detention would be if your site discharges onto an adjacent property and in that case if if a waiver was granted you'd be increasing the discharge onto the neighbor's property and thereby potentially damaging their property so that would be one of the circumstances that the waiver of the on-site detention would not be considered the next fairly major change to this on our open drainage channels currently the ordinance is set up so that land lying below the 50-year storm had to be contained within uh the uh the channel within the easement so we're changing that to a requirement for the the 100-year storm event instead so with that that land would have to be either the channel would have to be designed if you're if you're grading a new channel to convey the runoff from the head of your storm event uh in the case of an existing channel that is going to be in a common area or an easement that common easement will now have to cover the full area that would be inundated by the 100 year storm event and it will throw in here also that as we're we're talking about the 100 year event the 50-year event all of these storms we are updating the ordinance to state that those are based on the higher of the fema cues or urbanized discharge cues if none exists one would have to be calculated but that would be what the requirement with the with the drainage channels one of the more significant changes in the ordinance is that we are removing the design criteria that's been previously published in the ordinance and moving it into a separate drainage criteria manual and this has been in the works for a number of years and and so it's going to be really nice to have this readily available to everyone so we've taken that out of the ordinance the dcm however is referenced as part of the ordinance so it's being approved simultaneously with the revisions to the drainage ordinance the the main thing that is written into the ordinance for the drainage criteria manual is that as we go through and see the need to make revisions to our drainage criteria that revision can be approved by the city engineer without having to go back through the council and that's more of a time savings issue on on on going that route with it we have discussed it internally and so if we come up with any revisions to the criteria manual we will post those on the website we're looking at a minimum of 60 days before those revisions become effective so we're not going to try to spring anything new on anybody on anyone you submit a set of plans and all of a sudden some of the criteria change those will be posted another revision to the uh to the the ordinance and the design criteria will be for the storm sewer systems currently the ordinance states that storm sewer systems are designed for the 10-year event the streets have to be designed to carry the 25-year storm without exceeding the top of curves and we're going we're going to keep that requirement however we're going to change it to a 25-year storm event design and a lot of that has to do with just complaints that we receive on street flooding intersection flooding and it's just it's it's kind of a step to try to eliminate or at least reduce some of the occurrence of flooding situations that we come up with the next item and this uh previously i don't believe was in the ordinance where it where it's had any discussion concerning public and private storm servers so we've we've added language to the ordinance about public and private systems and this has been a a an item an issue that has come up uh several times over the last number of years concerning you know what's public what's private who's going to regulate what systems and so we've tried to explain or define some of the differences between the public and private so i'm going to read through these i know you guys are all capable of reading the slides just as well but just so we get it out there so the first criteria if all of the drainage storm water runoff on a development site if it's generated on that site the storm sewer system will be private and will be maintained by the property owner the city will not take ownership or maintenance responsibility for that type of system when we get to the private storm sewer systems and this is this will be a change uh in relation to how things have happened in the past previously the public and private storm service systems were required to be submitted to public works engineering for review and approval that will no longer be the case private storm steer systems will not be submitted to public works we will not review or approve them they will not be inspected by public works inspection staff instead the private storm sewer systems are going to be submitted to plan review in development services they will be responsible [Music] for the review of plans and their plumbing inspectors will be doing the inspection um i just wanted to jump in here and kind of give a little history when development services was uh taken out of public works and into development services it's its own department we have been in the process of trying to separate public versus private so they are going to handle all private and we handle anything that's in the right way so that's one of the reasons we're making this change um with that can you address what's going to be required for tap-in permits i think the tap-in permits will be the the same as they are now if you've got a if you are tying a private storm sewer system into a public system then that will be handled the same way it has been previously with a with a tap [Music] and cab feed permit is inspected by the fuel services inspector okay on this next slide our public storm sewer systems it'll be a it'll be a public storm sewer system if a off-site drainage area greater than or equal to six acres flows onto your development site we kind of kicked around what size that should be we landed at six acres that could be one that could possibly be a revision in the future a public storm service system will also be required if you have an upstream development and that storm sewer system discharges onto your development site whether that is a public system or a private system your system will be a public storm service system will be submitted to public works engineering for review all the public systems will still be submitted to public works for review and approval and here's one thing i do want to point out there's been a lot of question come up over the past several months we need to have a specific dedication of that storm sewer system to the city a lot of the of the plat dedications in the past have read that the streets and easements have been dedicated to the city for maintenance and we need to get we need to have you guys get real specific on that and and state that the storm sewer infrastructure is being dedicated to the city and that's that'll be kind of a change for you but uh make note of that it will eliminate a lot of confusion muhammad do you have a question uh thank you dave davids mohammed with smc consulting uh going back to the review of private storm system by the development services what type of design criteria they will be using to review the private storm system are they thinking to go to international plumbing code which is entirely different than what typically a site storm sewer system is designed thank you that's that's a good question muhammad uh here is the way that this is this is my interpretation of it i don't know that we've actually had that specific discussion yet uh my interpretation of this is going to be that your design of the system will still be the same design the the same design criteria that would you would use for a public system it's going to it's going to come down a lot to the plumbing code as they are inspecting the construction the one thing that we that we won't do you'll be able to as far as your on-site storm search systems you can set your design frequency where that's not really going to be reviewed as part of that private plan submittal so it's going to be a combination a lot of this is going to put the responsibility for coming up with the design criteria on to the consultants that we've had that requested a number of times why does the city get involved in reviewing uh public drainage system private drainage systems and so this is has been kind of our compromise on that i hope that answers your question yeah and we just will invite you with some additional um private storms to your criteria we can let you know get with development services and and we'll get some additional information back to you so i was just gonna mention that there are some discrepancy if we're looking at the plumbing code right now and the design criteria that we normally have such as the slope the minimum slope for plumbing code is one perce t but we are allowing half a percent or uh point four percent on our slope for the pipe so those are some discrepancy and also the from one manhole to another manhole they have a shorter distance than what our normal design are so we do aware some of the discrepancy between our design criteria and the plumbing code and we're still working to resolve those issue all right the next change that we are looking to make is on the floodplain activity permits we've had some questions and comments in the past concerning the requirement for fema elevation certificates for structures that are not within the limits of the fema map floodplain but that are within 200 feet of the boundary of that map floodplain so the new ordinance the new requirement will be that the fema elevation certificate will no longer be required for buildings or structures that are adjacent to and within 200 feet of a fema map flood plain however we still will have the requirement that in those situations for the two-part building permits where a a surveyor certificate or a surveyor's elevation certificate will be required prior to the issuance of the final portion of the building permit if the structure is within the limits of the fema floodplain it's a location that's had a longer based on fill or aloma based on phil or it just happens to be above and the fema floodplain covered that structure a fema elevation certificate will be required in those situations even if you show that oh that fema math flood playing may not be exactly correct we still have to honor that when we start looking at the female requirements and you will be required to do a fema elevation certificate [Music] so now back to debbie she's going to talk about this a little bit and then we'll open it up to two questions yeah i'll wait on the schedule we can go over that at the end but i was going to go ahead and open it up for any questions that you guys may have so so this is eric winger again i think you know one of the things that we have been asked several times is you know winter winter criteria manual updates happening with us the ordinance going to be updated and today is really that official day where we're starting that discussion we thought it was really important to come out to you as stakeholders to you as developers to use engineers and consultants to really have some input and be a part of the process making sure that we get everything addressed that's needed to be addressed over the past several years we have done a lot of research with surrounding communities to make sure that we're not over requiring or making changes that would not be similar or already in place with with our surrounding communities including norman and edmund and then as i mentioned when we kicked off the meeting we really wanted to put our best foot forward we did engage um two of our local consultants as i mentioned sniping polishwater with brian mitchell and johnson and associates tim johnson to receive a lot of their input to make sure that we would not bring things to you today during this meeting that we knew just would not be acceptable in oklahoma city so my thank you to both of them again for all their hard work it's been a long year's effort or more getting this ready but we're open to additional suggestions um we're looking for your support before we go forward and present any of the information to the city council um i think mark grabs has a question yes thanks debbie um so we mentioned the changes on the uh the drainage channel um the comment that it would be required to contain the 100 year by reading through that it's not only the 100 year but it's also an additional one foot of freeboard is that correct mark this is very uh that was not the intent of what we're writing so we'll have to go back in and look at that and and verify the intent section 5.5 oh it's in the drainage order of the criteria manual i have the criteria manual correct okay we'll look at that that was not the intent uh we wanted it to just cover the the limit the 100 year storm and then another thing that i noticed that wasn't mentioned in your overview on the changes to the detention not only are you requiring the multi-stage release storage but you're also requiring a foot of freeboard on the detention as well yes i believe that is correct we are we we are we are going to go with that requirement and then just one other clarification on the storm sewer the private versus public you've stated that on-site runoff uh generated on-site runoff would be considered private but i but and it's stated throughout the ordinance and the drainage criteria manual that way but i think clarity that if it's in the right-of-way in a public right-of-way but it's on-site storm sewer then it would be public or private [Music] good question that is another good question hey mark let us know i'm designing if i'm designing a residential subdivision that all the drainage is generated on-site no off-site but we're putting the storm sewer in the right-of-way then that's a big question in my mind okay well let us look at that and we can get back with you on what we come up with hey mark this is michelle one thing if you can uh send us your comment or question to the pw drainage so that we can have it documented and making sure that we don't forget uh you know forget about you uh from this meeting just want to make sure that you remember your question so we can have it addressed and it okay yeah and i've got quite a few more i was just it was just the points that were covered there i just wanted to make some clarifications on those highlights so guys the part the public is you have six acre coming to your site but we can address that and we can put those questions out and i'll respond to the web as well yeah we can have it figured out yeah we will look at that because that's that winds up with a private storm sewer within a public easement and that can create problems so that is an issue that we'll need to look at thank you mark um kendall dillon do you have a question yeah how how do we plan on implementing this um with new plats for the minute that it goes into effect and is adopted by council it's actually you know generally what i'm thinking is we design all of these positions that are perfection sometimes larger we've got phase built or used faces or however designed the whole thing comprehensively based upon the current ordinance detention in particular so if we've already started the subdivision do we now have to go back and try to figure out a way to redesign it to include detention or how are we going to hit those issues [Music] if there's something that's already under construction uh or already has a final plant that has been submitted and is in the review process uh that would be excluded from the the new requirements anything that's going forward though from the time that the ordinance becomes affected uh effective would be reviewed under the new criteria so it's very possible that you would have a multi-phase development where one or two phases have been constructed without a detention requirement the third phase comes in and it could it very well could require detention on that and that that's kind of the way it'll be reviewed um that will then it could fall under the uh the provision for a waiver uh but the but waivers are gonna be things that are gonna have to be proven by you to us uh as far as what the impact is going to be yeah certainly there needs to be some configuration and everything else because like i say and i i understand where you're coming from but even from an economical standpoint and everything else if you look at these developments that we've already got everything set up and then to redesign to add detention or to you know account storm sewer design and potential grade differences and those sort of things it's going to create a mess on a lot of these things so hopefully you know there's some consideration given to that to me it seems you know i know it's complicated i don't know they could be done but it'd be nice to just start new preliminary plots off with the current criteria kendall this is eric winger i think we want to work with you on that and we realize there's a lot of long-range planning that goes into some of the master plans that you and other consultants have worked on we are going to have to come up with a with a policy or a procedure on how to receive those i think what very answered is generally correct we may just need to be a little more forward about if you do have a plan like that that's a multi-year plan that you've already got a layout for that we just go ahead and receive it early and go ahead and have it have it recorded by public works that it's underway but what we have to avoid is two years from now getting a notice from a consultant that a plaque finally has a design and trying to retroactive something that old we just need to get notice of what those are now so we'll get that clarification to you and then we'll get a we'll get a procedure or policy issue so that you'll know how to submit those if you've got some plans that are already in that in that status sounds good okay uh muhammad do you have another question thank you debbie uh about that section 3.3 in the drainage criteria manual talked about capturing the flow on from carbon length on its street with gray and then there is a discussion about bypass flow uh what kind of design criteria are you looking into for consultants to show that how to show that what the bypass flow is and what is captured you're looking into hack 22 or other standards can you tell me where that is one more time muhammad i'm looking in that criteria manual to look to see where you're talking what you're talking about 3.3 yeah it's like it's a section 3.3.1 and subsection c and sorry barry we can also follow up with a written comment but i just thought to kind of discuss that find out from your thoughts is uh about showing for for consultant to show the bypass flow and the how the flow is captured from carbon led when those are at grade and not in some condition yeah i think what we're what we're looking for on that is really not anything different than what the criteria is now when you get to the to a sump location your storm sewer at that point is is going to be designed to it has to intercept the 50-year flow from that entire train space from the upstream areas as well so if you're picking up the the 25-year in your on-grade inlets when you get down to the to the sump that sump inlet has to pick up the 50-year for the specific basin that's draining to it plus the difference between the 50 and the 25 for the inlets that are upstream of that that that's the that's what the intent of that is which is which is exactly what's been happening uh for as long as i've been doing all this stuff here um and then from that once you get to that sump inlet then you have to you have to provide an overflow plume that's going to provide the difference between the 100 year storm and the 50 and again that's going to be for the entire drainage basin that would get to that sump location does that answer your question yeah uh partly the other related question will be that okay we address some condition uh now what happens on the ad grade carbon lit location where there is going to be a bypass what type of methodology you would like consultant to show how the bypass flow is calculated you know currently we are we're we're using uh and it goes into that section 3.3.2 where we have the inlet capacities and we would continue to use that if you get to whatever your design queue is and you put in a design 2-2 inlet it's going to intercept 18.2 cfs if you've got 28 cfs flowing in the street then you're going to bypass 10. and so it's going to be we're we're going to keep it that simple there's a lot of methods out there that you get into the the hec 12 have 22 methods and the the bypasses are they're really they're difficult to come up with not to mention that the inlets get larger the storm survive inlets get more frequent but that will be that'll be the the process that we would look at well i appreciate you simplifying it uh one more question and then i'll let you go uh section 4.3 where it talks about the minimum slope of like a half a percent and michelle touched on it earlier uh then there's also a discussion about meeting the minimum velocity criteria for a storm sewer uh we all know that sometimes storm sewer could be flatter than half person and is still able to show that velocity exceeding two and a half percent which is minimum so would that be easier to follow just one criteria or you have to have both criteria math velocity as well as minimum slope yeah i think that will be a a circumstance that we would have to look at on a kind of a case-by-case basis uh i think i i think we're all aware that there are times when a half percent slope is not going to be obtainable it you just can't get it and and and we understand that so what i would encourage on that is rather than just making the assumption that we're okay with that and designing it and sending it in send us an email give us a phone call let's address that up front we can look at it before you prepare your plans and make a determination yet we're not going to be hard and fast on these uh where we can't make any changes at all there may be some circumstances and you you send it in and say now i just can't get it here's the reason uh show us why you can't you can't maintain the half a percent we'll review it and if that looks like yeah we agree with that then we would we would approve a variance to this requirement uh i don't want to have a lot of of uh contact with where you know we get a call and say you just say well we can't meet a half percent slow can we get a variance of that well the answer to that would be no until you prove to us why you can't do it so when you make these requests back them up would give us some justification on that as well but say these are not cast in stone you have to do it this way and under every circumstance because it's not a one size fits all on storm server design barry is correct barry is correct and i want to uh make some addition to that is um we have seen a lot of uh slope that less than half a percent when we review plans and we also look at such as muhammad's design that he would usually show what is the velocity having the less than half a percent slope and if it's more than two and a half percent foot per second we'll be okay with that so so we do consider um a couple different factors not just like if it's not uh meeting minimum half a percent then we're rejecting so so we do consider that i just want to add that to the conversation thank you michelle okay stephen you've been very patient stephen tipsy yes thanks debbie um i said a couple of of comments um one just to reiterate on the private storm sewer i think that'll be critical to nail down that the criteria that development services is going to use just so we're all clear of how we're going to our drawings and plans are going to be reviewed so um just just want to reiterate that make sure we get that clarified going forward my comment with the overflow structure for detention so section four in the free manual it talks about um kind of at the top of the page on page 31 the overflow structure shall function uh discharge elements fully blocked uh without exceeding the allowable historic discharge rate so the way that we and i may be misunderstanding this but the way that reads is that you're basically going to have two outlets you're going to have a primary outlet structure that's going to control all your storm events but then you've also got to design this concrete overflow structure to also control your storm event with respect to so i just wanted some clarification on that and what the thought process was on that stephen that's a a question that we've gotten from another consultant as well um and that's one thing we need to look into a little bit it may be that we we go back and look at this and and make a revision to it that the overflow structure would have to to pass the 100-year storm without over topping the pond dam it it may be a little difficult to put in a primary outlet structure that's going to control all of our frequency storms and th n put in an overflow structure that would also limit only the 100 year and so that's that's what we want to look at i think the intent of this really was that we have an overflow structure for the hundred year storm in case all of them you know somebody throws a mattress in the detention pond and blocks up the whole thing we want the we want to be able to get the water out without over topping the pond dam because that's when we start running into a lot of problems uh if you start over topping that embankment so we're going to look at that that's a that's a good question and we did have that come in from another consultant as well yeah no that that sounds good i mean i think the not over topping the damn that that makes sense and having that spillway basically as a release so that you don't have a catastrophic failure i mean that that makes sense to me so i appreciate the response yes and one thing if i can just reiterate what michelle had mentioned when when mark grubbs was asking questions while ago if you guys could we're trying to take notes on all of these questions right now but it it i don't take shorthand and so there could be some things we missed so if you can use the comment form and email those in or if you just send an email that would work too but send them to that pw drainage at okc.gov that way we'll have a written record of every comment and question that you guys have so that we don't get it don't overlook anything we want to be sure that that we take into consideration all of your uh questions and comments all right thank you is there anyone else who has any questions alec i like that yeah debbie um section 6.5 with the underground attention it lists the allowable materials and that's rcp uh pvc and hp i just wanted to confirm where the contact metal metal systems intentionally omitted here they were not uh intentionally omitted uh we're looking at some modification to this that would allow uh the only one i've been reque i have seen the request on so far is the ads uh thermoplastic chambers uh and and you know we're looking at that being i think they've been used in several places already so we're looking at adding that in there if you can send uh in your in your comments send the request with that specific uh system and we'll we'll look at it darren smith i just want to be i just want to ask you be willing to provide us with a participation certificate i believe this qualifies for pdh requirements in our license yeah sure we can do that baron thank you i'm a little far behind [Laughter] mohammed do you have another question thank you debbie uh this moment again uh bear uh or michelle uh would you mind looking at section 6.2.1 and did me talk about it a little bit more more where it talks about uh analysis of the offsite upstream area in detention analysis to be considered as fully urbanized or in historic condition for detention design i think muhammad i think the the intent on the historic conditions since we are now looking at a the the situation where uh citywide the requirement will be to provide detention for every site and in this specific instance would fall under that condition where we would not grant a waiver uh because you've got offsite area draining onto an adjacent property that being said that would then say that the off-site property is providing detention because they're now draining on to your adjacent property your existing condition then would be the historic or the existing conditions of that property not uh the urbanized uh condition that makes sense i'm with you i am i i mean we thought the same way kendall and our engineering group we always thought the same way that off-site area shouldn't be considered as urbanized because they're supposed to provide their own detention and i was disconnected for a few seconds so i completely couldn't hear all your reply barry but uh if i get the meaning of it uh you are saying that the offsite of the stream area will be considered uh historic conditions that that is that is correct and we consider this to our condition hey muhammad this is michelle so the the current analysis is we're taking the upstream uh off-site as urbanized for both existing and proposed this is to make sure that you your detention point or your site is allowing the offside urbanized to pass through it but not detaining any since you have to see the same for both existing and proposed and we don't we we have less control currently per the current ordinance we have less control on the detention pond so we don't want your site to flood however with the new adoption of the ordinance revision and the criteria manual it allows us to have more control on all the detention pawn on site so with that adoption we would be allowing the offside upstream as the c of 0.5 with the existing condition because every site would have to provide on-site detention point unless there is an analysis to show no negative impact to downstream uh adjacent property owner thank you maybe one one quick addition there we would use and and not to not contradict what michelle was saying directly but if that if the if the site offsite is draining on to you if it's currently developed and it's a and it drains on to you and but it was not required to provide attention when it was done it may be a school or a shopping center that comes on to you you will have to consider that in its existing condition whatever that happens to be i agree with that michelle that makes sense i got lost for a little bit and what we've done in the past the way we looked at this is we would always do the storm sewer design assuming no detention was in place and now that decision is required everywhere we're able to look at it a little more like michelle said we have a little more control and we can look at it and say oh there is detention here you can design this for what's coming outside yeah the intent of of the having offside urbanized is because we don't have that much control and and we try not to flood the the onsite downstream um and we do see you know we do consider every possibility if you can show let's say the downstream uh propos the downstream existing storm sewer was designed having urbanized offside which is your site that means the downstream storm sewer is adequate to take in your urbanized flow so detention pawn may not be required so we kind of we look into those as well so just feel free to give us a call if you have any question in prior of design of your site we'll be happy to help anyone else have a question going once just okay well i will talk about our next steps that we have coming up we do have another public meeting like this one next friday so if some didn't get to attend this one we have that one available we would like to have your comments uh back to us by march 26th so we can go through those and revise the ordinance and get into a final form we would like to introduce this to city council the end of april there would be a public hearing uh may the 11th and it would be approved may 25th and if it's approved on may 25th 30 days later it would go into effect so those are the the final steps and i appreciate everyone who's participated those were some really good questions guys one comment here for everybody gets off i think on the website i have put in there that they we need to have their comments by march the 5th that gives us a chance to go through those and get and make sure what we want to do before by march 26th so if you could have your comments just by march the 5th that would be great because we do need to have a little bit of time to go through those and make responses so i apologize for that thank you barry hey debbie is that on your previous slide that we can probably show it on the screen there you go if you guys want to write that stuff down or if you have any questions just let us know give us a call but comments and revisions by march the 5th and and
