PROPOSAL/SUMMARY
1 As the Planning Commission is aware, for t e past year we have been working on the city's
Surface Water Management Plan. This i : a 3 phase effort designed to present the city with
improved wetland protection, a surface water management plan, and a surface water quality
improvement program. The program has begun to produce a wide variety of results including
enhanced street sweeping to removexutrient laden mate s before discharging into the lakes,
a new wetlands protection ordin . 'and official maps , ch the Planning Commission will
soon have an opportunity to r vv, water quality improv ent projects, done either as new
separate construction or • a;` ements to ongoing city and 'vate developments, and our
' ongoing educational effo One of the program's produc hich should have a major
positive impact tit , osion and Sediment Control
Best Managem R Rrligim. t *; * .e 40 I rk n handbook that
contains what i c .ne mandatory construction practices or u •:; our
community. It is desi tied°- �e that the most appropriate erosio ¢ ,t. and site
ty g � n ��
1 management techniques are inco . �` 1 � , as I i s g and using
appropriate sections from Best Management .c : e I an • s ooks prepared by the Board of
Water and Soil Resources and by the Minne , _ ollution Control Agency. It also includes
some design specifications developed by Bo = oo and by our City Engineering Department.
It will result in a much more coordinated and high quality approach to this major water
quality concern. For instance, while we are concerned with the long term impacts of
urbanization on lakes and wetlands, we find that erosion from a large scale construction
project such as a residential subdivision can equal 10 to 15 years of normal impact on a lake
in one construction season if it is not managed properly.

I The proposed ordinance amendment is a simple one. It simply bases a reference to this
handbook in both the city's subdivision and zoning codes. The handbook itself is then
I handled as an operational manual which can regularly be updated by the City Engineer on an
as needed basis. A copy of the handbook is attached for your review. We would appreciate
it if you could return your copy to us at the Planning Commission meeting so that we may
I utilize them again when the City Council reviews it. Once the ordinance and handbook is
adopted, we will undertake to print permanent copies which will then be sold to developers as
I needed.

1 STAFF RECOMMENDATION

October 7, 1992 - Page 70
Farmakes: My concern would be the valuation of what the realities of the
marketplace would be comparatively to what aesthetically we would like to
do. Because I don't know if we're terribly familiar.
' Michele Foster: we'll make sure that you hear that so I don't think you
need to worry.
' Farmakes: It's sort of a two way communication thing.
Batzli: But I agree. I think with Chaska's planning comments in a broad
sense and apparently that's all really, give the opportunity to look at it
in kind of a broad things to look at it. Consider it and I think those arE
some of the same things we're looking at for better or worse. I hate to
agree with them but he's right. No, I'm just kidding. We like Chaska. Sc
' I would, as long as the applicant doesn't mind, I guess I'd like them to gc
back and review it a little bit more with staff. Is there a motion to
table?
1 Emmings: So moved.
Ahrens: Second.
' Emmings moved, Ahrens seconded that the Planning Commission table the
Concept PUD for Gateway West Business Park for further review. All voted
in favor and the motion carried.

Batzli: You can if you want one.
' Emmings: I don't know why you'd want to do that to yourself.
Ahrens: You can have my copy.
' Emmings: And mine.
Bruce Buxton: The reason I ask is because I'm an engineer and...
Emmings: I don't think that will help.

Batzli: The minute we approve this, you can have one.
Emmings: You can have 5 of them.
Krauss: Well actually, feel free to give yours out Joan but I'd like toll
keep the rest of them to give them to the Council. This isn't the final
printing. We do have some corrections.
Batzli: I'm going to keep mine. '
Emmings: You're asking us to vote on something that I have no idea what
the hell it is, you realize that? '
Krauss: I had to write a report on something I had only the foggiest idea.
Krauss: Okay, there's no one else in the crowd that wants to address the"
Commission.
Ledvina moved, Emmings seconded to close the public hearing. All voted 11
favor and the motion carried. The public hearing was closed.
Emmings: 1 just have one question. Dave, should we do this? You're an'
engineer, should we do this?
Hempel: Yes. We have put together.
Emmings: That's enough.
Hempel: Okay. '
Emmings: Nothing you say is going to help me understand this.
Batzli: Does anyone else have any comments in regard to adopting this
our ordinances?
Ahrens: No, I think it's a great idea. I've been waiting for this for al
long time.
Batzli: This is actually fairly significant from the standpoint I think,'
that it goes hand and hand with the wetland alteration permit process and
setbacks and things that we're going to talk about. Because we are I think
now on the verge of shrinking the setbacks and things like that and we ne
something to enforce and to make sure the wetlands are protected as we mo
closer to wetlands here so, this is actually a very important part of tha
process. So it's something the wetland, the swamp committee has been
working on in connection with these consultants. So I think it's a good I
step. Is there a motion?
Ledvina: Ah yes. I'd like to move that the Planning Commission recommenll
that the amendment to Sections 18 thru 62 and 20 thru 94 referring to the
Chanhassen construct site and erosion and sediment Best Management
Practices Handbook be approved.
Batzli: Is there a second?

Farmakes: I'll second it.
Batzli: Is there any discussion?
Ledvina moved, Farmakes seconded that the Planning Commission recommend
approving the Zoning Ordinance Amendment to the City Code concerning
construction site erosion /sediment control requirements as presented in the
Best Management Practices Handbook. All voted in favor and the motion
carried.
' APPOINTMENT OF PLANNING COMMISSION REPRESENTATIVE TO THE TREE PRESERVATION
BOARD.
' Ahrens: I'd like to nominate Tim to the Tree Preservation Board.
Emmings: Absolutely. Second.
' Batzli: I don't know that Tim really wants to preserve trees, from what
I've heard.
Emmings: Tim and I share a lot of opinions about that.
Batzli: You're not a tree hugger either?
' Emmings: No. Not if they're on my property. I don't want the City
telling me what to do with any tree on my property.
Ahrens: Oh one of those.
Emmings: I'm taking down three oak trees you can't get your arms around.
' It's costing me $500.00 a tree. You ask why I do that to myself.
Batzli: Why?
' Emmings: I have to. I have too damned many trees. I can't see anything
and there's a lot of reasons you might want to take down a tree. I still
have 20 you know.
' Ledvina: They're not dead?
' Emmings: No. One is dying and the top fell off a second. But I sure
wouldn't want to have to come to the City and ask if I can take these trees
down because I don't want them where they are.
' Ahrens: Did you write that down what he's planning on doing to his trees?
Krauss: Yes, we'll send the police out there.
' Farmakes: The tree police.
Emmings: I welcome you to come to watch. When you get there all you'll dc
is hear the chainsaws and I'll be running.
