PUBLIC HEARING 5.1 SUBDIVISION (SUB) 2006-00011/PLANNED DEVELOPMENT REVIEW (PDR) 2006-00002/SENSITIVE LANDS REVIEW (SLR) 2006-00011 FERN HOLLOW SUBDIVISION— Continuation from May 7, 2007 REQUEST: The applicant requests approval of a 7-lot Subdivision and Planned Development (PD) on 1.59 acres. The lots are proposed to be developed with detached single-family homes. Lot sizes within the development are proposed to be between 3,496 and 5,964 square feet. Sensitive Lands Review is required for slopes greater than 25%. LOCATION: The project is located south of SW Durham Road PLANNING COMMISSION MEETING MINUTES—June 18,2007—Page 1 at the terminus of SW Copper Creek Drive;WCTM 2S114BA,Tax Lot 15300. ZONING/COMPREHENSIVE PLAN DESIGNATIONS: R-4.5: Low- Density Residential District. The R-4.5 zoning district is designed to accommodate detached single-family homes with or without accessory residential units at a minimum lot size of 7,500 square feet. Duplexes and attached single-family units are permitted conditionally. Some civic and institutional uses are also permitted conditionally. R-7: Medium-Density Residential District. The R-7 zoning district is designed to accommodate attached single-family homes, detached single-family homes with or without accessory residential units, at a minimum lot size of 5,000 square feet, and duplexes, at a minimum lot size of 10,000 square feet. Mobile home parks and subdivisions are also permitted outright. Some civic and institutional uses are also permitted conditionally. Planned Development;PD. The purposes of the PD Overlay zone are to provide a means for creating planned environments through the application of flexible standards which allow for the application of new techniques and new technology in community development which will result in a superior living arrangement; to facilitate the efficient use of land; and to preserve to the greatest extent possible, the existing landscape features and amenities through the use of a planning procedure that can relate the type and design of a development to a particular site, among other purposes. APPLICABLE REVIEW CRITERIA: Community Development Code Chapters 18.350, 18.360, 18.39.0, 18.430, 18.510, 18.705, 18.715, 18.725, 18.730, 18.745, 18.765, 18.775, 18.780, 18.790, 18.795 and 18.810. Commissioners Fishel,Anderson,Muldoon and Doherty reported site visits. Commissioner Fishel advised that she was absent from the May 7th meeting,but has listened to the audio tapes of the meeting and has reviewed all the materials. She would like to participate in tonight's meeting. STAFF REPORT • Gary Pagenstecher referred to his June 11th memo to the Planning Commission. He noted that the applicant has submitted a revised narrative and supplementary materials for the development. The proposal is now for a 6-lot subdivision. The revised proposal is largely consistent with standards,with the exception for access to lots 3, 4, and 5. Two areas that remain for Planning Commission discretion include the buffer from Durham Road and pedestrian connections to the open space. He advised that staff originally recommended denial, but is now recommending approval. APPLICANT'S PRESENTATION Ken Sandblast, Planning Resources,Inc., 7160 SW Fir Loop, Suite 201, Portland 97223, reviewed the revised submittal materials and responses to previous Planning Commission questions. He noted that some of the slopes are in excess of 67% and he still does not PLANNING COMMISSION MEETING MINUTES—June 18,2007—Page 2 believe that it is feasible to construct a pedestrian path there. He would like this condition of approval removed. He reported that Tract B is a private street. Sandblast advised that the entire vegetative corridor boundary area is regulated by Clean Water Services (CWS). There will not be any retaining walls with double digit heights. For the most part, the building setbacks will be 8' or greater. The reduction in density did not change the road location or the utility design. He noted that there is a shared driveway easement for lots #3 and #5. The retaining wall has been relocated and is entirely within lots #4 and#5. Mr. Sandblast believes the purpose of a PD is to allow flexibility for sites with a lot of restrictions or constraints. This site has topography, configuration, existing access, natural resources, and existing CC&R issues. The benefits to Tigard for this PD include building more compatible detached homes rather than attached housing; extensive buffering of the drainage way; and protection of existing vegetation. One Commissioner agreed that this is a challenging development spot and noted that the land on the slope is already protected. That land can't be developed. He likes the idea of less development (5 lots rather than 6), so more trees could be preserved. Sandblast provided details about protection of the site and the grading and erosion control plan. Gary Darling,DL Design Group,Inc., 9045 SW Barber Blvd., Suite 101, Portland 97219, advised that the plans the Commissioners had were preliminary plans. There is.a condition of approval to prepare a 1200C application, requiring detailed drawings for erosion measures. They also have to provide a plan showing the site as it is, stockpile locations, and hazardous materials locations. They cannot get a permit until they provide this detailed set of erosion plans. It was advised that a path to the creek is not allowed per CWS. The applicant was asked if they had considered 5 lots instead of 6. Mr. Sandblast answered that they have already gone from 7 to 6 lots and that going fewer would probably not pencil out economically. They are meeting the minimum density requirement at 6 lots. They had looked at other options for layout of the development, but didn't see a dramatic difference. Gary Pagenstecher provided information on how density is calculated. He said it is figured on net buildable area. Density transfers can be added. For this site, 5 is the minimum supported in the code. He believes there's a benefit to it. Barring that benefit, no other one has been articulated that isn't already protected under CWS. From the Planned Development point of view,based on discussions the Commission has had, there is a compelling reason to consider reducing the number of lots. PLANNING COMIVIISSION MEETING MINUTES—June 18,2007—Page 3 Dick Bewersdorff recommends allowing 6 units. The developer has followed the previous Planning Commission recommendation to reduce the number of lots and to ask for another reduction would be inappropriate. Commissioner Walsh disagreed, saying that they did not have all the information originally, so they could not make a determination earlier. He does not think it is too late to ask for 5 lots. Bewersdorff responded that, given the process and the difficulty with developing this site,unless the Commission has specific experience in designing subdivisions,it's not an appropriate request. Mr. Darling said that he believes a fence would be required along the buffer. Kim McMillan provided information on required erosion control measures and permits. She detailed the permit and inspection process. Mr. Sandblast handed out his proposed list of revised conditions of approval (Exhibit A). He discussed the proposed changes with the Commission. PUBLIC TESTIMONY—IN FAVOR Scott Haring, 13325 SW Genesis Loop, Tigard OR 97223, testified that he is the owner of the property. He conveyed the steps he went through trying to design the project and going from 7 lots to 6. He described his plans for the property and advised that he intends to save whatever trees he can. He noted that there are certain CC&Rs that he has to follow. Justin Geel, 7403 Bradmar Dr., Edmonds,WA 98026, advised that he is the nephew of the owner and will be the developer. He reported that for most developments, the last 1-2 units end up being the profit for the development. He is comfortable with 6 units,but will have a difficult time doing just 5. The purpose of this development is to provide something that is aesthetically pleasing, green, and profitable to the local residents. They will do everything possible to save trees. He advised that he intends to begin using materials that are green, renewable; or recyclable for units he is currently developing in Seattle. His goal is to leave most of the area natural and not to encroach upon the greenspace. Braden King, 1322 4th Ave. NW, Seattle,WA 98177, signed up to speak,but chose not to. PUBLIC TESTIMONY—IN OPPOSITION Greg Sorenson, 16260 SW Copper Creek Dr.,Tigard 97224 spoke about a past windstorm in the area and the need for buffering to protect trees. He expressed concerns about the impact to livability and extra traffic from this new development. He described existing traffic problems in the neighborhood and provided details about past erosion problems further south on Copper Creek. The creek has eroded property and the Homeowners' Association has used neighborhood funds to help with restoration of property. Chris Edmonds, 10065 SW Kent Place,Tigard 97224 testified that she wrote the letter that was sent to the Commission on May 8th [in the Commissioners'packets]. She believes the PLANNING COMMISSION MEETING MINUTES—June 18,2007—Page 4 development needs to fit in with the character of the existing neighborhood. She does not like small 3,500 square foot lots. She is also concerned about the setbacks. Commissioner Doherty advised that with the revised plan, the lots are now 5,000-6,000 square feet. APPLICANT'S REBUTTAL Ken Sandblast noted that the developer has to follow what the code requires. The Planned Development code gives the ability to be flexible. He does not believe that the result of removing another lot would be dramatically different. The traffic issue would not significantly change between 6 lots and 5 lots. The local street will not be over capacity. He requested that the Commission approve the subdivision as revised. Kim McMillan advised that because there are more than 2 lots sharing an access,it needs to be on a private street. The private street could extend to just the south end of lot#3. The sidewalk,which is required by code, could be on one side. That could meet the criteria for access and lot#5 could access off of Tract B. President Inman said the sidewalk seems to go from somewhere to nowhere and wonders if it adds needless impervious area. Staff advised that the sidewalk requirement is a guideline, so it is within the Planning Commission's authority to waive the sidewalk requirement. No sidewalk will be required. PUBLIC HEARING CLOSED The Commissioners expressed their appreciation to the applicant for thoroughly responding to their earlier questions, for designing a development with larger lots, and for considering "green" development. Staff was asked about the conditions of approval. The applicant had asked for strikeouts of conditions #18 and#27. Staff advised that conditions #1, 2, 14, 27, 41,43 could either be stricken or left as is because the applicant has done them. It was advised that the Homeowners'Association has access to maintain the trees by the creek. It was noted that a potential pedestrian crossing of the creek is not being required as a part of this development;it is not appropriate to address this as part of the approval. Approval of the development does not change the public's right to access that area. It was suggested that when there's a continuation of a public hearing, the land use sign be put up on the property again so citizens could be aware of another hearing. Commissioner Vermilyea moved to approve Subdivision (SUB) 2006-00011/Planned Development Review (PDR) 2006-00002/Sensitive Lands Review (SLR) 2006-00011, subject to the findings in the original staff report,plus the findings that were provided by the applicant, and as amended at the meeting. Commissioner Hasman seconded the motion. The motion passed unanimously. PLANNING COMMISSION MEETING MINUTES—June 18,2007—Page 5 6. COMPREHENSIVE PLAN UPDATE Darren Wyss provided an update on the Comprehensive Plan Update project. He reported on the Policy Interest Team meetings,future meeting scheduling, and responses to comments made at the May 21St Planning Commission meeting [memo to the Planning Commission is included in their packet materials]. Ron Bunch advised that the Policy Interest Team meetings are open to the public and the Commissioners are welcome to attend and contribute if they choose. The Commission asked that key words, such as sustainability,be defined as they will be used within the Plan. That way, someone one else won't make their own definition of those words. Wyss advised that the Plan will have a definition section, so everything will be covered. Wyss noted that the purpose of the Policy Interest Teams is for citizens to tell us what they want to see in the community and help us craft their ideas into policies or action measures. 7. OTHER BUSINESS Ron Bunch reported that recommendations for Downtown Urban Design Standards will be coming to the Commission shortly. He also talked to the Commission about training with an outside consultant. The Commission decided to hold a training session on July 2nd, from 6:00 p.m. to 9:00 p.m. 8.
