The project consists of a 500 square foot bedroom addition. Applicable Regulations and Guidelines: 5.0 lowa City Historic. Preservation Guidelines for Additions 5.1 Expansion of Building Footprint 5.2 Decks and Ramps 8.0 Neighborhood District Guidelines 8.1 Longfellow Neighborhood Staff Comments This house was built around 1890, and is a good example of Victorian residential design from the late 19tii century. It is a hip roof structure with projecting gables on all four sides, providing the sense of irregularity popular in the Queen Anne style. This house can be considered individually significant in terms of architectural design and integrity. The curved porch was restored using original railings and banisters. A two - car garage located in the Northeast corner was converted into a studio. The applicant is proposing to build an addition with a limestone foundation to match the existing foundation. The bedroom addition will include a fireplace (not requiring a chimney), bathroom with steam shower, and laundry facilities. Painted wood clapboard siding to match the rest of the house will be used in addition to aluminum clad wood Marvin ultimate double hung windows. The trim details such as watertable, corner boards, window trim, gable fishscale siding and barge board details will match the original. The low -hipped roof will be Black TPO or membrane roofing (not the shingles shown in the drawing) The Guidelines for Additions emphasize the importance of preserving the character and features of the historic house, while designing an addition that is both compatible with and distinguished from the historic house. Additions should be built in the rear of the property, if possible, and should match the roof pitch and type of the original structure. Maintaining and continuing important horizontal lines is also a requirement of new additions. The guidelines recommend using windows that are of a similar type and proportion to the existing windows. Foundations of additions should appear similar to the historic foundation in color, texture, unit size, and joint profile. Siding, trim, and roofing materials of the addition should match the existing historic house. Staff finds that he proposed project matches he ttmm, siding, foundation and window requirements of the guidelines. The windows in the rear bay will be separated by a 6" trim space similar to a traditional stud pocket. This paired window pattern is found in the west bay of the historic house. While the project is placed at the rear of the property according to the guidelines, it does project beyond the west fapade. Staff finds that this is an acceptable way to allow the applicant the necessary interior space in the addition. The bump out is similar to the gabled extensions on the main house. The roof pitch of the addition will be low to avoid the central second floor rear window on the historic house. This roof pitch is also typical of historic one-story rear kitchen additions or porches. The low pitch will requite membrane roofing instead of shingles. Membrane roofing is an acceptable material for lowpitchroofs and on this house should be black or gray.

The project consists of relocating existing windows to improve the interior space by allowing a standard height kitchen base cabinet. Applicable Regulations and Guidelines: 4.0 Iowa City Historic Preservation GwdelinesforAlterations 4.11 Siding 4.13 Windows 8.0 Neighborhood District Guidelines 8.1 Longfellow Neighborhood Staff Comments This house was built around 1920, and began as a hip roof cube cottage. This type of house was commonly built as worker housing in the early 1900s. Grant Street and the surrounding area were developed following the completion of the Rundell streetcar line in 1910 and the construction of Longfellow School in 1917, It provided housing for the growing middle class —both blue collar and white collar workers. There was a dependence on new forms of transportation, including automobiles, which increased the desire for independent, detached houses. Whi1e this house has been considered a marginal contributing structure in the Longfellow Historic District, several factors result in staffs opinion that it is currently non-contributing. The front porch roof has been added and the front stoop extended. A full -width rear addition and new full basement have been added. The new addition includes a full rear porch and ganged ribbon windows. Other new windows have been added to the sides of the house. The north and south side windows in the front room appear to have been double -hung windows which once matched the front window. They have been replaced with small square windows. Asbestos siding was added in the late 1930s or early 1940s and the exterior trim was also modified at that time. These alterations are extensive and have impacted the historical character of the house. The applicant is proposing to replace the south side front window with a double -hung window matching the front window. The head height will be raised on the new window to match the front window. The remaining existing south side windows will be raised to match this head height and allow for a standard height kitchen base cabinet on the interior. All siding, trim, and shutters will be reused for the existing windows. Trim for the new double -hung window will match the trim on the front window. The application originally proposed relocating the existing windows but it was determined that the double -hung window would add light as the applicant wanted without moving the ganged window into the historic portion of the house. As windows are one of the most important elements that define a building's architectural character, the Historic Preservation guidelines recommend retaining historic window frames and making repairs instead of replacement. If an opening is to be relocated, it should not detract from the overall fenestration pattern. On a framed structure, appropriate siding that matches the existing should be used with its members being placed across and randomly extended beyond the opening. Since the windows were altered on this house, staff finds that moving toward an original appearance with the windows is preferred. By replacing the window in the front room with a window matching the front facade and raising the other windows to a traditional head height, the applicant will improve the historic character of the house. Staff finds that eventually replacing the north window in the front room with a double -hung window should also be approved. The replacement windows should match the window on the front of the house. Staff finds that either a new wood or new metal -clad wood window would be acceptable on this property. The guidelines recommend repairing historic wood siding and trim or salvaging other historic siding. Since neither the trim nor the siding on the house is original, staff finds that matching the existing trim, or reusing it when possible, is an acceptable proposal for this house.

Davenport Street District: Goosetown/ Horace Mann Conservation District Classification: Contributing The applicant, Zach Evans, is requesting approval for a proposed alteration project at 411 E. Davenport Street, a Contributing property in the Goosetown/ Horace Mann Conservation District. The project consists of adding a canopy over the window well to a previously approved basement egress window. Applicable Regulations and Guidelines: 4.0 Iowa City Historic Preservation GuideGnesforAlterations 4.7 Mass and Roofliries 9.0 Guidelines for Additions 5.1 Expansion of Building Footprint Staff Comments This house was constructed in 1881, according to Tax Assessor's Records and is located in the Goosetown/Horace Mann Conservation District. It is named for Julius Haberstroh, a carpenter and pressman for S.W. and C.S. Mercer, who purchased the house in 1881. This home is an example of a common vernacular residential house form in Iowa City during the late 19t� and early 20t" centuries: the Gable -Front form. This home has a low-pitched gable roof and no porch or dormers. The home has some alterations including replacement siding, an added door hood, and a one-story wing added after 1985. In July 2015 the Commission approved a basement egress window and window well for the property. At the time of the project, the window well was to be installed in the side of the rear patio slab because the basement extended under the slab. The window well was going to have a lowprofilesteel grate compliant with city code. The window was moved forward and placed in the side of the side -gabled addition. Without approval or a permit, the applicant added a canopy cover over the egress window well instead of the original steel grate. The applicant says that the canopy is necessary to prevent water and debris from infiltrating the window well and to prevent residents from falling into it. The side of the house with the window well is the main access route between the front and back yards. The canopy consists of a shed -roof with posts to the concrete window well and shingles to match the house. The guidelines recommend window wells match the material of the foundation but do not include any guidance to allow a roof canopy built over them. Drainage is typically handled in the bottom of the well. Historically window wells have not included roof canopies. In Staff s opinion, water infiltration into a window well can be prevented or removed through the use of appropriate gravel, drainage, and tiling in the base of the window well. When this is possible and a low -profile grate is available to prevent accidents, staff recommends tiling and drainage as a preferred solution with a grate if necessary. Debris can be removed as a part of general periodic home maintenance not requiring an alteration to the building. With the new proposal, the applicant proposes the steel grate is insufficient a barrier to prevent residents from falling into the window well because of the proximity of the window well to the property line and fence. An entry canopy could be considered one method to resolve the problem but the low elevation and placement on the side of the building does not fit any historic guidelines and makes the canopy obtrusive and unusual, further degrading the historic character of the home. Because of this lack of historic precedent and ability to comply with the guidelines, staff finds that the canopy does not meet the requirements of the historic preservation guidelines. For the water issue staff recommends improving drainage as the first solution. If this solution works, staff feels the originally proposed grate should be sufficient to prevent residents falling in the window well Recommended Motion Move to deny a Certificate of Appropriateness for the project at 411 E.

HARVAT HALL MEMBERS PRESENT: MEMBERS ABSENT: STAFF PRESENT: OTHERS PRESENT: Thomas Agran, Esther Baker, Zach Builta, Gosia Clore, Sharon DeGraw, Cecile Kuenzli, Pam Michaud, Frank Wagner Kevin Boyd, Andrew Litton, Ginalie Swaim Jessica Bristow, Bob Miklo RECOMMENDATIONS TO COUNCIL: (become effective only after separate Council action) CALL TO ORDER: Vice Chairperson Baker called the meeting to order at 5:30 p.m. PUBLIC DISCUSSION OF ANYTHING NOT ON THE AGENDA: There was none. CERTIFICATE OF APPROPRIATENESS: 310 South Governor Street. Bristow said this property is in the very north section of the Governor/Lucas Street Conservation District. She said that it is currently non-contributing, because of the vinyl siding, a hodgepodge of replacement windows, metal soffits, and the removal of the porch. Bristow stated that it was a vernacular Victorian house. Bristow said the applicant proposes to put an egress window and window well on the south side of the house where the driveway and garage are located. She said the work had already been started without a building permit and had to be stopped. Bristow showed the location of the house. She said the owner put this in as just a metal window well, but to meet the guidelines, he will have to put in something that matches the foundation. Bristow stated that it is a brick foundation. She said that brick is more time-consuming to install than concrete block so that concrete block would be acceptable, especially because the brick does have a parch coat, and the owner has indicated he would also do that. Bristow said it would be like a stucco coating that would match the parch coat and would be on a window well. Bristow said the owner proposes to put in a vinyl casement window that has a divided light, in order to look like a double hung window. She said that there are a variety of windows on the house. Bristow said that vinyl is an exception that can be made for a house in a conservation district, especially when it is going into a basement. She said that, considering the amount of vinyl that is already on this house, it is probably appropriate in this case. MOTION: Wagner moved to approve a certificate of appropriateness for the project at 310 South Governor Street as presented in the staff report. Agran seconded the motion. The motion carried on a vote of 8-0 (Boyd, Litton, and Swaim absent). HISTORIC PRESERVATION COMMISSION December 8, 2016 Page 2 of 7 1125 East Burlington Street. Bristow said this property is a one and one-half story house in the College Hill Conservation District. She stated that the house is a Queen Anne Victorian. Bristow said that in reading the history of this area, some of these houses, including this one, were built for middle class families. Bristow said the application was oriainally for a basement egress door, which is no longer in the plans, and replacement of the decking. She said there is an existing deck in the back. Bristow said it was built before the district was established and is grandfathered in to extend a little bit further to the east than would normally be allowed. She stated that the owners are not removing the structure. Bristow said they are keeping all of the structure but want to replace the deck board material. She said part of the reason material has already been removed is because the deck boards had rotted and someone had fallen through. Bristow said the owners would like to use Trex, which the Commission has approved in the past for decking. She noted that this is a conservation district and involves a deck at the back of the house. Bristow said that the railing that the owners had before did not meet the guidelines for design, so the owners know they will have to put in a new railing, with the top and bottom rail, to meet the guidelines. She said that, instead of using wood, the owners have proposed to use a Trex material. Bristow said staff finds this material does not appear to be paintable and looks like a plastic material so it does not meet the guidelines. She said staff feels that cedar is readily available, easy to work with, and will last a long time in this kind of installation. Kuenzli asked if the owners are planning to paint the deck floor and the railing. Bristow replied that if the floor is Trex, it won't actually be painted. Kuenzli asked if the spindles would not be painted either. Bristow answered that if the Trex material is used, they probably would not be painted. Bristow showed samples of the railing material that the owners want to use and the flooring material they want to use. Bristow said that if the owners are required to use cedar, they will paint or stain the railing to match the deck. Kuenzli suggested that the wood might be less expensive than the Trex. Bristow said she is uncertain about the cost. She said that cost is not necessarily something that the Commission can consider. Bristow stated that for the owners, she believes it is more about the longevity of the material. She said the owners want something that they don't have to paint or stain, which is not necessarily the Commission's goal. Bristow said the Commission would like to see somethino that looks appropriate: which would be a wood that would be paintable or a wood replacement product that would be paintable. Bristow said that there are exceptions in the guidelines for the use of Trex as a decking. She said, however, that so far, anything that is used as wood replacement needs to be paintable and have the appearance of wood. Bristow said the Trex railing material seems to feel plastic as well as appear plastic. She said it would be up to the Commission to decide if it wants to approve that material. Miklo clarified staffs recommendation is to allow the Trex for the flooring but not for the railing HISTORIC PRESERVATION COMMISSION December 8, 2016 Page 3 of 7 Agran said he thinks the Trex is more expensive, but the sales people state that it saves on labor and maintenance. He said that cedar does not last if it is not kept painted or stained. Agran said that Trex is a premium product in that sense. Agran said, with regard to Trex, as related to other products that people use for siding and other things, oftentimes there is a fake wood textured side and also a flat side. He asked if this product was like that. Bristow said the sample board shows a variety of textures for that board product. She said she told the contractor that she was interested in the smoothest version, and she pointed out that sample to the Commission. Bristow said the owners would be using that, but it does not come with a completely smooth side like cement board. Agran said there is texture on both sides so that it is not slippery, but one side has a fake wood grain and one is more of an even texture. He stated that with other products, the Commission has specified that the fake wood grain side should not be facing out. Bristow said the Commission has given approval for a back porch using a (Fi-Pon?) material. She said it comes in a chalky white and has to be painted. Bristow said it has more solidity than the Trex material but still has to be painted. Miklo said that using the material would be an exception. He said that if the majority of the Commission felt that this should be wood material such as cedar or treated lumber, the Commission could require that. Miklo said staff recommends approval of the Trex for the deck itself. Agran said he believes that if the Commission would make an exception, there should be an explanation of why that would be. He said he thinks it is okay to use Trex, because this is on the back of the property not the front. Agran said that of all of the things on the deck, that is the most difficult to maintain with paint. He said it is the tread/flooring, whereas the railing paint lasts longer. Agran said that is why he would think it is okay. MOTION: DeOraw moved to approve a certificate of appropriateness for the project at 1125 Burlington Street as presented in the application with the following conditions: the new railing is constructed following the guidelines, the skirting either remains or is reconstructed, the railing is constructed of wood, and the Trex material with the less grainy texture is appropriate to use for the decking. Michaud seconded the motion. The 411 Davenport Street. Bristow said the applicant for this project has asked that it be postpone until January. REPORTS ON CERTIFICATES ISSUED BY CHAIR AND STAFF: Certificate of No Material Effect - Chair and Staff Review. 407 Brown Street. Bristow stated that this project for a house in the Brown Street Historic District involves the re - shingling of the garage and main house. She said that the porches in the back and front both have metal roofs that the owners considered recoating. Bristow said she spoke with the contractor, and he regularly uses a black modified bitumen roofing which is put on with heat. HISTORIC PRESERVATION COMMISSION December 8, 2016 Page 4 of 7 She said she spoke with the contractor at length about possibly using it for that internal gutter, which needed some minimal repair but not a complete overhaul and about how this might work as the last step before it is redone. Bristow said the contractor has used that in this kind of an application. She said it is not yet known what the longevity is, but it is a commercial roofing material and has the potential to be good in an internal gutter application. 728 Dearborn Street. Bristow said this project involves adding a radon system. She said that it will be around the corner on the back and will be painted to blend with the house. 624 Grant Street. Bristow said this is going to be a reroofing project. She said that staff has been working with the contractor, who has been recently starting to work in historic districts. Bristow said the contractor wants to put big, galvanized metal whirlybirds on all of his roofs for ventilation. Bristow said that is not really appropriate as far as something that looks historic. She said that it looks very industrial - very contemporary and modern - and is not something that has been allowed when it can be viewed from the street. Bristow said that this house is on a corner, so it does not have a good side to put this on. She said staff talked to the owner and roofing manufacturer about other venting options. Bristow said staff showed the contractor that there are other options. She said the homeowner is completely comfortable with that. Bristow said staff believes that something as modern as the whirlybird venting is not appropriate on an historic property if it can be seen from any street. Minor Review - Staff Review 715 South Summit Street Bristow said the owners are going to remove all of the aluminum siding on this house. She said the original plan was to cover all of the original siding with cement board. Bristow said they now plan to remove the aluminum siding and restoring the original wood siding. Bristow said there is a 1906 photograph showing some of the house details so that the owners can replace any of the trim that might no longer be there. She said the owners will reuse as much as the original siding as possible. Bristow said that cement board might work in a large area as long as it is blending with the siding. 828 Dearborn. Street Bristow stated that this property was owned by a contractor who flipped it and did a really good job on the back 60s-70s addition. She said staff has been working with the new owners to not take out and replace all of the windows that the previous owner had restored and rehabbed. Bristow added that the owners added a railing to the front steps. HISTORIC PRESERVATION COMMISSION December 8, 2016 Page 5 of 7 Intermediate Review - Chair and Staff Review. Bristow said that both intermediate reviews involved minor changes to certificates that previously came before the Commission. 328 Brown Street. Bristow said that originally, the stairs for the addition on this property were going to come straight off the back, kind of facing toward the garage. She said that for a variety of reasons, the stairs will now come off the side, which is what staff preferred originally. Bristow said that as a minor change, it qualifies for intermediate review. 829 South Seventh Avenue. Bristow said this review involved the Habitat house. She said that the entire house ended up being lifted up out of the ground a little bit more than anticipated so that now a railing is required on the porch. Bristow said the minor review is adding a railing to this house. She said the railing will be a typical top and bottom rail with square spindles and will meet the guidelines. Bristow added that the porch floor was not supposed to be cantilevered out of the ground this much. She said the applicants are going to mask it with landscaping, and if that fails, staff will work with them to come up with some kind of plan for skirting. Bristow said that it was supposed to be at grade level, and that is why it is concrete in the first place. CONSIDERATION OF MINUTES FOR NOVEMBER 10, 2016: MOTION: Agran moved to approve the minutes of the Historic Preservation Commission's November 10, 2016 meeting, as written. Clore seconded the motion.

She presented photographs and information about the nominated properties, as prepared by the subcommittee, and the Commission ratified the list. Bristow said the awards would be held on Thursday, January 19, at the Iowa City Public Library at 5:30 p.m. with a reception to begin at 5:00 p.m. MOTION: Wagner moved to approve the nominations for the Historic Preservation Awards. Michaud seconded the motion. The motion carried on a vote of 8-0 (Boyd, Litton. and Swaim absent). COMMISSION INFORMATION AND DISCUSSION Bristow said that there is a conflict with the June 8 meeting, because the Preservation Summit is that same week in Fort Dodge. She did not know if anyone from the Commission or staff would attend, but if the desire is to move the meeting, that should be done now because of scheduling. Bristow said that it could be moved to the next week. The consensus of the Commission was to move the meeting to the next Thursday. Bristow said she would look for a meeting room. HISTORIC PRESERVATION COMMISSION December 8, 2016 Page 6 of 7 Bristow said the State sent an e-mail announcing a Webinar to be held on Wednesday, December 21. She said the Webinar will discuss the federal historic tax credit program. Bristow said it is from 1 p.m. to 2 p.m. for those interested. Regarding the Houser -Metzger house, Bristow said that all but two of the basement windows have been installed. She said the furnace will be on shortly, and there is electrical to most of the building. Bristow said she needs to work with the electrician regarding small changes that need to he made and with the plumber ahout specific work to be done. Bristow stated that the hole where the chimney was in the first floor has been filled. She said they are working on filling the hole in the second floor. Bristow said then the wall for the chimney will be framed up. Bristow said there is porch floor on the back porch. She said she is working on getting the floor for the front porch soon, and it will probably be reclaimed wood. Bristow said that mulch has been delivered, and most of the site has been covered. She said that makes it less muddy for now. Bristow said people have been working out of the garage and will be moving this weekend to work out of the basement. She said the materials will be stored in the garage. Bristow said there will be upcoming workshops, including interior painting and windows. She said there will be multiple opportunities for both skilled and unskilled volunteer labor. Bristow said the house does not yet have water but has heat and electricity. Bristow said there will be an end -of -the year fundraising drive. She said she will be sending a flyer to all of the members of Friends of Historic Preservation and perhaps also the Commission members to try to get funds for any end of the year donations one would want to make. Bristow said they will be asking for money for specific items.
