Review of Minutes – October 10, 2013 meeting 2 Commissioner Menn moved, seconded by Commissioner Katz, to approve the October 10, 2013 Architectural 3 Control Commission (ACC) meeting minutes without corrections. On a voice vote, the motion was 4 unanimously carried. 5 6 5. Design Review Permits – Northbrook Public Library: Revised Building Material (Second Request) 7 8 Background Information 9 Mr. Poupard briefed the Commission on the history of this project. On October 9, 2012, the Northbrook 10 Public Library (the “Applicant”) received approval of a small addition with a new façade for the first floor. On 11 August 8, 2013, the Applicant returned to the ACC seeking approval of a material change and a replacement 12 of rooftop mechanical equipment with the installation of new screening. The ACC approved the change in 13 façade material and also to the replacement of the mechanical equipment with screening. 14 15 Current Proposal 16 Due to a need to reduce the costs of the project, the Applicant is requesting to revise the facade cladding for 17 the first floor building addition. In lieu of the approved Trespa and Centria panels, the Applicant is now 18 proposing to use white corrugated metal cladding. Material samples have been submitted. The Applicant 19 has submitted revised elevations on how the material will look where the new cladding is required. 20 21 The architect explained that the change in materials will result in a significant cost savings for the Library. 22 23 The ACC reviewed the proposed façade material change and found it to be appropriate. 24 25 David Menn moved to recommend the material change as presented and Cliff Town seconded the motion. 26 On a voice vote, the motion carried unanimously. 27 28 6. NorthShore 770 Development (NW corner of Skokie & Dundee) 29 Mr. Schoon briefed the ACC on the status of the Plan Commission’s review of this project and summarized 30 the changes made to the building designs. The application has been submitted by Morningside Crossroads 31 Partners. The ACC reviewed the revisions to the design features of the building, signage and landscaping for 32 the proposed NorthShore 770 mixed use development at 770 Skokie Boulevard 33 34 Staff from HKM Architects (HKM) responded to the comments made at previous Plan Commission and ACC 35 meetings. A summary of their revisions are as follows: 36 37  Reduced Building Height - Reduced number of units from 416 to 342 units. The revised building is no 38 longer 10 stories and is a combination of 8 and 9 stories. 39  Reduced Floor Area – The floor area has been reduced and has a reduced footprint at the north end. 40 This will allow more pervious surface and will allow room for additional shade trees. 41  Reduced Podium Height – The height of the podium was reduced from two floors to one floor. 42  Increased Parking Ratio – The overall number of parking spaces for the apartment building was reduced 43 from 703 to 599. 44  Amenities – As suggested, the swimming pool was relocated to the south green courtyard. 45  Parking Level – The heavy cast stone was replaced by brick at the ground floor. This will reduce the 46 appearance of such a large building.  Page 3 Minutes of the November 14, 2013 Architectural Control Commission Meeting 1  Lobby – The heavy cast stone was removed in favor of a Trespa panel. Trespa is a decorative, high 2 pressure compact laminate (HPL) panel with an integral surface. The copper patina color of the panel is a 3 timeless color that reads softer than stone. 4  As requested, brick masonry was added to the dominant material and the synthetic stucco was removed 5 from all locations. 6 7 The ACC and the Applicant then discussed W-T Engineering’s proposal to use CPVC for the water system. It is 8 not currently acceptable with the current local amendments to the plumbing codes. CPVC is a product from the 9 Lubrizol Corporation. This product is being introduced to be more economic. 10 11 Mr. Reupert noted that most north shore communities still require copper and prohibit CPVC. Tom Higgins, the 12 manufacturer’s representative, stated that Lubrizol Corporation will provide trained technicians that are 13 engineers. These technicians can then train the installers of the building. 14 15 There are cautionary measures that need to be taken including leaving expansion room and expansion loops 16 when you get into long runs. The plumbing contractors will need to take recommendations from FlowGaurd and 17 build that into the specifications. It was recommended to stay away from “female” adapters and use brass 18 adapters. Each unit will have its own hot water heater. It will not be a common system. This product can 19 handle up to 180 degrees and 73 PSI’s. 120 to 140 degrees will be the average range of temperature. The 20 developer’s intent is to build it and own it. Not to build it and sell it. 21 22 Mr. Poupard noted that that the Village does not have to amend the current code, and the Building Official can 23 make exceptions on a case by case basis. We are seeking the advice of the ACC in reviewing this request. He 24 recommends that if the ACC does approve, it is required that the cautionary measures be spelled out as a line by 25 line item. There was a concern that a 4-inch pipe could burst if not secure. This can happen because a pipe and 26 coupler are not completely joined. The smaller pipes are more flexible. Most of the larger 4 inch pipes will be 27 inside the heated garage thus avoiding any UV issues. 28 29 The cost saving from CPVC to copper is significant. ACC members noted that they want to ensure the longevity 30 of the building and consider the effect of our code. The CPVC has not been allowed previously and the ACC does 31 not have experience with this product. They discussed both FlowGaurd Gold and Aquatherm have a 10-year 32 warranty. 33 34 The ACC’s concerns on this product were the possibility of leaching, the safety of the material which may 35 deteriorate and get into the water supply, and how to avoid contact with materials or substances that could 36 cause the CPVC to deteriorate. The ACC would like a comparison CPVC to Copper, and investigate the 37 capabilities, fire stopping material, and will continue to conduct additional research. The ACC would also like to 38 see samples and a brief demonstration for educational purposes. This would be necessary for the ACC to a 39 recommend a code exception for this project. 40 41 The ACC discussed the materials and color of the building. The Applicant changed the colors based upon 42 suggestions made from a previous meeting. Overall, the colors were lightened up. The color panels were 43 adjusted to complement the brick masonry. The reddish cast stone used at the lobby area and ground level was 44 replaced by black brick. Brick masonry was added as the dominant material and the synthetic stucco was 45 removed from all locations. 46  Page 4 Minutes of the November 14, 2013 Architectural Control Commission Meeting 1 The residential feel of the proposed residential building was well received. The color palette and the materials 2 will allow the building to look like a quality structure in 20 years. The windows are white vinyl and there is a 3 slider door in the corner units. The ACC recommended that this project be approved. 4 5 An email from Plan Commission member Elfant was presented to the ACC discussing the entire project. It was of 6 the opinion of one individual that this building had neither a modern look similar to the Optima Old Orchard, nor 7 a stately look which incorporates a mix of masonry materials. 8 9 The Applicant stated that a green roof was requested by the Plan Commission on the 8 th floor, but it would not 10 be cost effective. The Applicant state that few people could see the green roof and therefore it was a waste of 11 financial resources. Additional financial resources were utilized to add the proposed changes and the new water 12 reclamation efforts. 13 14 At Panera, the Plan Commission suggested that an emergency escape lane be installed so that drivers could get 15 out of line in the drive through at Panera. The ACC discussed the drive up window and Applicant believes that 16 aesthetically it is the wrong thing to do. 17 18 Robert Katz made a motion that the ACC recommend the North Shore 770 project as presented with the 19 following stipulations: 20 21 1. The ACC approves of the changes of the exterior and mass of the structure. 22 2. The ACC feels the change in colors are an improvement. 23 3. The ACC would like to see more details on the outside corners where the metal meets metal. 24 4. The change in the windows at Mariano’s is an improvement and should be added to the plan. 25 5. Panera drive-thru lanes should be kept as is and not include the emergency escape because the existing 26 landscaping plans provide a buffer from the street view. 27 6. The rain screen color of Patina was well received. The ACC is requesting the color and size at final plan 28 stage. 29 7. The detail of the patterns and fasteners of the Trespa panels need to be shown to the ACC. 30 8. Green roofs are not necessary on the 8-story buildings due to their limited visibility. 31 32 Davie Menn seconded the motion. Upon a voice vote, the ACC unanimously approved the recommendations. 33 34 Robert Katz would like to discuss the possibility of what the ACC looks at. He noted that the Commission spent 35 countless hours on Walmart and that was a waste of time since they withdrew. 36 37 Mr. Poupard suggested that the role and responsibility of the ACC be include on the agenda of the next meeting. 38 39 7. New Single Family Elevations: 40 1539 Sunset Ridge Road (proposed north lot) – R-5 zoning; Arzoumanin & Co., Architect 41 1539 Sunset Ridge Road (proposed south lot) – R-5 zoning, Arzoumanin & Co., Architect 42 43 Mr. Poupard noted that this involves a pending subdivision as the Applicant was seeking to move the lot 44 line. 45 46 David Menn made a motion to approve and Bob Katz seconded he motion. On a voice vote, all motion was 47 unanimously carried.  Page 5 Minutes of the November 14, 2013 Architectural Control Commission Meeting 1 2 9. New Business 3 There was no new business 4 5 10.
