Main Street Date:Friday, June 21, 2019 4:58:44 PM Attachments:image009.png image010.png image011.png image012.png image003.png Hi Sara, Here are comments from building: 1. Historic portion East property line fire separation distance of 3’-5” complies with IRC (change in use to single family) if fire sprinklers are installed. (2015 IRC R302.1) 2. Historic portion West property line fire separation distance of 1’-0” requires 1 hour rated wall and no windows or eave overhangs allowed. The existing condition is similar but with a few more inches of clearance on the West (but then less on the East) (2015 IRC R302.1). However, 2015 IEBC 1205.3 allows the existing historic exterior wall and opening situation to remain due to a change of occupancy to an equal hazard category. The applicant must submit a report per 2015 IEBC 1201.2. 3. The new addition is 3’ from the East and West property lines. This requires either a fire sprinkler or 1 hour fire rated wall with windows no more than 25% of wall area and 1 hour fire rated eave overhangs no closer than 2’ to the property lines (2015 IRC R302.1). Applicant should verify with the Parks department that a fire sprinkler line can feasibly be installed. 4. Emergency escape and rescue opening window wells have grates and appear to be adjacent to walkways- requiring guards per City policy.

Main Street Date:Thursday, June 27, 2019 4:22:55 PM Attachments:image001.png image002.png image003.png image004.png image005.png Sarah, Engineering comments are as follows: 1.Stormwater - The application makes no reference to how onsite runoff will be captured and treated for water quality. The proposed plan does not leave much room for stormwater treatment. Prior to HPC approval the applicant shall provide information on a conceptual level of how rainwater will be treated. 2.Excavation Stabilization - The proposed excavation stabilization plan is very constrained. If any work or layback is proposed to be done on neighboring properties, an agreement between the property owners must be submitted to the City along with the building permit. Micropile walls cannot have any impact on neighboring properties. 3.Water service line – at building permit, the applicant shall work with the Parks and Engineering Departments to determine the best alignment of the new water service line. Any plan shall minimize impacts to the street trees. The application mentioned removing the tree in the front yard so it is my understanding there will be no onsite utility tree conflicts. 4.Public improvements – at the time of building permit a 6’ sidewalk will be required. The sidewalk shall follow the COA “floating sidewalk” detail to avoid tree roots. New curb and gutter will be required. A one sided pour on the back will be required to protect the existing tree roots. A 2’ asphalt t-top patch will be required.

I feel confident HCE can work through each option and arrive at a stormwater design that works for the current HPC proposal and meets Engineering standards. Let me know if you have any questions or if HPC needs further information. Thanks.

Main Street Date:Thursday, June 20, 2019 5:00:08 PM Attachments:image001.png image012.png image013.png image014.png image015.png Hi Sarah, Parks comments: On page 19, applicant is asking for a removal of the front tree. As there are two trees in the front yard, 1 deciduous and 1 coniferous, we need to know which they are inquiring about. What are the limits of excavation in front yard? This will require discussion with the City Forester to see how close to the cottonwood trunks they can disturb. On pages 5 & 30, Waiver request for Parks Dedication fees will need approval of Manager of Parks. DBH on cottonwood trees are the same on both surveys, one dated 9/24/2012 and the other dated 3/21/2019. Will need to verify sizes. If ENG is requiring sidewalk to be replaced it must be of a floating design and no excavation can occur within the driplines of the existing cottonwoods. Any activity in the front yard will require discussion with the City Forester as it is entirely within the driplines of the cottonwoods. This includes staging of house while the basement is being dug. The waterline for both 202 and 208 W Main is in between the 2 cottonwoods and a discussion will need to be had between ENG and Parks to determine the best location for the new waterline.
