Recent questions about hydrology and trucks

If we are using the stormwater collected from the green roof for the irrigation of the greenery, do we have to treat the water further?

  • No, you don't need to treat that any further if you are using it to irrigate the property (not the Part 303 wetland).

When it comes to placing the retention pond, can this be placed near a wetland/ incorporated into an existing wetland to just enhance its ability to hold the water?

  •  See the post about the site visit.  Basically no, you cannot.

How detailed do you want the site plan to be for the final memo? Originally you said it could be a very basic design, but our feedback makes it seem like our entire team should have their design finished. 

  •  You definitely don't need to have a final site plan.  We fully expect that you will have to modify it throughout the semester. The hope is that you have an initial idea of where water will flow in the system. As Dr. Li told one of the students, "the site plan needs to be concrete, detailed and "complete" (in terms of the objects to be included and layout, and connections), but the plan will certainly evolve throughout the semester".

Do we have a number of trucks that consumers have in their fleet as well as their types so we can use those numbers for air pollution and the car washing water demand? 

  • I asked my contact at Consumers about the number of trucks and they said they were still in the programming stage.  I counted about 45 trucks on the aerial photo of the Willow Street site. I just went back over the newspaper articles which mention the plan to expand operations.  So perhaps 75 trucks.  I would say, assume that 60% of those are single-unit (SU-9) design trucks and 40% are semi (WB-19) type.  I've copied Dr. Ingle on the email since he and I discussed this this afternoon.
Can the GANTT chart we submit be the one that we are using with our entire group if all of our things are added to it or do we have to make our own with just ENE and Hydro due dates and deliverables?
  •  Yes, the GANTT chart can be the one that your entire group submitted, with the requirements for the ENE and hydrology specialists added.  If there are critical decision points needed to meet the deliverable due dates then please add them.

Height restriction

I had mentioned the 35' height restriction in class. Here's where I got the 35' restriction: http://www.windsortwp.com/wp-content/uploads/Ordinances/WindsorTownshipZoningOrdinance2012.pdf The 40' is documented here: https://library.municode.com/mi/windsor_charter_township,_(eaton_co.)/codes/zoning?nodeId=PT110_110.000ZOORORNO25_ARTX_110.1000DE_110.1002DE If any of your buildings are to be greater than 40' in height, the owner will need to apply for a variance.  This document provides general information but hopefully this helps to explain the process: https://www.acgov.org/cda/planning/ordinance/documents/Variance.pdf . From what I've seen by serving on the Meridian Township Environmental Commission, this is accurate.  The code document I gave you should also help: see section 110.402, 110.404.  You can also try to see if there are other 2+ story buildings in Windsor Township.  From my experience, if the township has...

Update: Feb 12, 2024

Greetings, I thought I would do another update since we do not have class this Tuesday. I heard through the grapevine that there were some concerns/frustration/thoughts among the ENE students. I thought I would try to address them.  I think much of the challenge is that the ENE roles depend greatly on the other specialty areas.  Here's an example - I believe the transportation specialists are planning to put the truck entrance on N. Canal Road just south of the "restricted construction" area in the north west corner of the site.  However, this puts the entrance much closer to the area zoned as residential and thus has the potential to compromise the health, safety, and well-being of the public.  I would argue that the transportation specialists should be working with the ENEs to find a location that is suitable and protective of the public. Jack Cooper Transport is located across the street from the CS site on Billwood Highway and the county has already agre...
