The proposal would include 3,700 square feet of ground-floor retail and 44,000 square feet of commercial space. The proposal would also include the addition of a traffic signal on Gilman Blvd at the Three Trails Crossing. This agenda bill seeks Council input to determine if the City should explore a potential development agreement for the Gilman Lofts project in response to the above request. State law authorizes a city to enter into a development agreement to establish the development standards and other provisions that will apply to, govern and vest the use, development and related mitigation of the property for the duration specified in the agreement (RCW 36.70B.170). Development agreements must also be consistent with the city s applicable development regulations. The Administration recommends pursuing a development agreement for the Gilman Lofts project at this time to: 1. Provide a development that meets the City's vision for this property as part of the Central Issaquah Plan as well as the developer's vision for a positive redevelopment of the property; and,
2. Allow for the development of a vertically-mixed use project (commercial over retail) in lieu of a single-story, big-box retail building that has already been permitted; and, 3. Establish the terms for partnering with the City for the construction of a signalized intersection at the Three Trails location. If the Council is supportive of the Administration working on a development agreement with the applicant, this process would commence in January 2017 and be brought to the City Council by March 2017 for action. Consistency With Comprehensive Plan: LU Policy A13 Use innovative land use tools such as Transit-Oriented Development, Transfer of Development Rights, Development Agreements, Inclusionary Housing, Form-Based Code etc., to optimize community benefits. LU Policy C2 Focus future growth in: a. areas with no or minimal environmentally critical areas; b. vacant platted lots in areas with existing public facilities; c. areas where infill and redevelopment can occur with less environmental impacts due to the degree of existing development; and d. areas where clustering development can protect environmentally critical lands and preserve and protect remaining forested hillsides. LU Policy J5 Design and create trails, sidewalks, bikeways and paths to increase connectivity for people by providing comfortable, direct or convenient links between: a. Residential neighborhoods b. Schools c. Recreation facilities and parks d. Employment centers e. Shopping and service designations f. Community gardens, and g. Transit EV Policy A2 Pursue transportation and mobility solutions, as addressed in the Transportation element. EV Policy A5 Facilitate economic development by encouraging public/private partnerships, and consider procedural incentives and financial tools in order to leverage private resources where there is a compelling community benefit. EV Policy B3 Work to attract businesses that create a diverse economic base, providing high quality employment opportunities and provide goods and services desired by the community. A diverse economic base includes businesses that provide goods and services for the everyday needs of Issaquah residents, businesses and visitors; and, a variety of income opportunities that allow residents and job seekers to find advancement employment opportunities within our community. EV Policy B4 Encourage private investment through development and redevelopment that uses land efficiently and contributes positively to economic vitality. T Policy A3 Support multi-modal transportation solutions including general purpose lanes, High Capacity Transit, HOV lanes, transit and nonmotorized improvements that implement the Roadway, Transit and Nonmotorized 20- year plans (Figures T-2, T-10 and T-4). Use the best available technologies when implementing these projects. T Policy B3 Foster a mobility system that reduces the negative effects of transportation infrastructure and operation on the climate and natural environment. T Policy B4 Seek the development and implementation of transportation modes and technologies that are energy-efficient and improve system performance. T Policy B5 Develop a mobility system that minimizes negative impacts to human health. T Policy C1 Use a system-based concurrency management system to fund growth s share of impacts to the City transportation system and support the City s preferred land use pattern and vision. T Policy C4 Increase the City's multi-modal usage by 2035 by supporting, expanding and implementing transportation choices including High Capacity Transit, HOV lanes, transit and nonmotorized improvements, and other Transportation Demand Management solutions. Use the best available technologies when implementing these projects. T Policy C5 Provide a seamless multimodal system that maintains the City s adopted Level of Service as defined in the Land Use Code. T Policy I1 Use the Nonmotorized Improvements Maps (Figures T-4 and T-5) to guide the design, construction
and maintenance of pedestrian and bicycle facilities by public and private parties, including the preparation of design standards and elements that promote a pleasant and safe traveling environment. T Policy I2 Direct nonmotorized resources towards those modes that have the least environmental impact and the greatest contribution to livability. T Policy I6 Use impact and mitigation fees, grants, and other revenue to construct and maintain nonmotorized projects identified on the Nonmotorized Map (Figure T-4) that are not otherwise included in roadway projects. T Policy J2 Monitor and find ways to reduce the number of nonmotorized collisions. T Policy L6 Require new or redeveloping properties to design and build bicycle/ pedestrian corridors that maximize the use of nonmotorized transportation alternatives. Administration's Recommendation: The Administration recommends moving forward with exploration of a potential the development agreement with Seacon Issaquah Studio Lofts, LLC for the Gilman Lofts project; and approval of the resolution as presented. Update: Update 1 (February 21, 2017): The proposal to enter into a development agreement with Issaquah Studio Lofts, LLC was discussed at the Council Land & Shore Committee on the following dates: December 1, 2016 January 5, 2017 January 18, 2017 February 2, 2017 The conversations at Committee focused on two primary parts of the proposal: 1) what is the community benefit to enter into a development agreement; and, 2) whether the Council will allow this project to move forward during the moratorium. Community Benefit The 3-trails crossing was identified on the City's non-motorized mobility plan as a number of trail users are not using the pedestrian signal located west of the trail alignment. The plan calls for a signalized intersection and lists the cost at $1.4 million. By partnering with the developer on this improvement through approval of the proposed development agreement, the City would save taxpayers approximately $1 million. Without a development agreement, the developer would be required to finance the installation of a "C" curb on Gilman due to the increased traffic expected on the site. The "C" curb would turn the driveway to Pogacha into right-in/right-out only driveway. This revision to Gilman would have a significant negative impact to the businesses along the north side of Gilman from 3-Trails to Front Street due to the reduced access. Exhibit B provides a visual comparison of the "C" curb versus the signalized intersection. The Committee discussed the southern leg of this proposed intersection. Although a final design for the Juniper/Rainier leg has not been completed, the Committee believes the benefits of this proposal are worth moving forward. Moratorium The proposal is for a mixed-use (retail and office) project with structured parking and connectivity to the adjacent regional trail. In looking through the six moratorium work items, the proposal could be altered by the outcomes of the two below work items: Architectural Fit & Urban Design - The applicant has agreed to allow the Development Commission to use any draft guidelines created by the City's consultant in their project review. District Vision - It is likely the Gilman neighborhood will still desire office development as part of the vision. This proposal would add jobs to this neighborhood.
Note, there is a timing issue for the developer as construction will occur on Gilman this summer to install water main connections. Allowing the traffic signal conduit to be installed at the same time will provide an essential cost benefit to the developer. Budget The financial commitment from the City to partner with the developer on the signalization is $375,000. As this project is listed on the non-motorized TIP, it could qualify to use monies from the Pedestrian/Bike Mitigation Fund, which currently has a balance of $107,427.83. The recommendation from Administration is to use $75,000 from said fund, and $300,000 from the General Fund ending fund balance. Council Land & Shore Committee Recommendation At the February 2, 2017 meeting, the Committee recommended (2-1) authorizing the Mayor to enter into and execute a development agreement with Issaquah Studio Lofts, LLC. The Committee further recommended the following additions to the signalization project be included in the draft development agreement: Bus stop in project vicinity Project interface with the trail, providing an attractive edge These changes, as well as additional revisions recommended by the City Attorney, are included in the draft development agreement, attached as Exhibit C. Next Steps 1. Schedule and conduct a public hearing. 2. Make a decision on the proposed development agreement. 3. Direct the Finance Director to include $375,000 in the next 2017 budget amendment. Update 2 (March 20, 2017): At the Council meeting of Feb. 21, 2017, staff presented: 1. The Applicant's proposal to partner regarding the construction of a signalized intersection at Gilman and Juniper. 2. A development agreement that would allow the project to move forward in advance of the lifting of the moratorium. Following deliberation, Council directed the Administration to prepare a resolution seeking approval of the proposed development agreement (Exhibit D); and schedule the related public hearing for the March 20, 2017 City Council meeting. The development agreement being requested by the applicant is for two purposes: 1) to allow for the project to move forward during the current development Moratorium; and, 2) to partner with the City on the construction of the 3-trails traffic signal. Although the IMC specifically identifies Cluster Housing and "Transfer of Development Rights Development Agreements as Level 5 Reviews, a development agreement that does not grant an increase in entitlement or a modification to existing standards is not identified in the Table of Reviews (IMC 18.04.100-1) and; therefore, does not have an adopted noticing process. Pursuant to IMC 18.01.050, the Development Services Director is given the authority to interpret IMC Chapter 18, where necessary. It has been determined adequate noticing for this hearing has occurred, which included posting of the subject property and publication in the newspaper of record. At Monday's meeting, staff will provide a brief presentation. Council action is anticipated to occur following the hearing. Update 3 (April 17, 2017): At the March 20, 2017 Council meeting, staff provided a presentation and the required public hearing was conducted (opened and closed). The following individuals spoke in support of the proposal: Steve King, Pogacha Restaurant Sarah Barnes, Pogacha Restaurant Rob Henderson, Rob's Transmission Shop
Ed Evans David Kappler, 255 SE Andrews St. Victor Saleman, TSI Solutions Bob Powers, Issaquah Studio Lofts Steve Pereira, 170 NE Dogwood Place, questioned the community benefit of the proposal. Following Council discussion, it was moved by Goodman, seconded by Pauly to: Approve Resolution No. 2017-03, approving the Gilman Lofts (Three Tails) Development Agreement; and, direct the Finance Director to include $375,000 in a subsequent 2017 budget amendment, utilizing $75,000 from the Mitigation Fund and $300,000 from the General Fund ending fund balance. Further questions and conversation ensued, however, rather than voting on the motion to approve the development agreement, Council unanimously postponed the motion to the Council meeting of April 17, 2017. The Administration was tasked with providing more information specifically regarding the project s relationship to the adjacent trail; and, vehicular impacts for N.W. Gilman Blvd., Rainier Blvd N. and N.W. Juniper Street. In response to Council's request, the following information has been provided: Trail Connectivity The applicant provided Exhibit E illustrating an enlarged view of the proposed project and the connection to the East Lake Sammamish trail. Decorative paving, trees and benches could be added to create an inviting connection between the trail and the proposed project s plaza area. The final design of this plaza would be reviewed by the Development Commission as part of the permitting process. Traffic Evaluation In order to respond to the questions raised by Council, staff requested CH2MHill evaluate: 1. The impact and function of the intersection with the installation of the proposed signal. 2. The proposal for a 5 Legged signalized intersection. In response, a memo summarizing intersection traffic options and data table showing the intersection's level of service for both current and future traffic volumes have been provided (Exhibits F, G). This information demonstrates the signalized intersection would have the following level of service impacts: The Proposed Signal option creates an intersection operating above City standards in 2017 and 2030. The 5 Legged signalized option would meet level of service standards for the City in 2017. In the future, if no other improvements were made, this option would fall below the City's currents level of service standards. Additionally, either signalized intersection will be safer and easier to cross for pedestrians and cyclists. Currently, pedestrians and cyclists are required to cross several hundred feet west at a location that does not directly align with the existing trail system. Signalizing the intersection will provide the opportunity to more directly connect the trail system and provide a more logical crossing point on Gilman. Signalizing this intersection will give all users clear guidance on when to make turns so the overall performance of the intersection will function more safely. Strip Retail and C Curb Without a development agreement, the Currently Permitted alternative ("C" curb) would be installed. If this installation were to occur, the Juniper leg of this intersection would fall below Council-adopted level of service standard sometime between 2017 and 2030. The City received a letter from the applicant on April 5 (Exhibit H). The letter indicates that if the parties cannot agree on the terms of a development agreement and allow the Lofts project to move forward in advance of lifting the moratorium, the owner will be forced to pursue a single-story, surfaced parked, retail project on this site, and
installation of a "C" curb. Next Steps At Monday s meeting, the motion to approve the development agreement (Resolution No. 2017-13) is before Council. Other action may be taken, e.g. amending the motion, withdrawing the motion, or further postponing the motion to a date a time certain. Staff will be present to answer questions. Alternative(s): Do not commence negotiations enter into a development agreement with Seacon Issaquah Studio Lofts, LLC. [Impact: Seacon Developer may move forward with the construction of a single-story, big box retail building; and/or, retreating from their proposal to cost share a signalized improvement of Gilman Blvd at the 3-trails crossing.] RECOMMENDATION Council Land & Shore Committee / Stacy Goodman, Chair: MOVE TO: Refer AB 7219 to the Dec. 1, 2016 and Jan. 5, 2017 Council Land & Shore Committee meetings for review and recommendation, returning to the full Council on Jan. 17, 2017. MOVE TO: Direct Administration to prepare a resolution approving the proposed development agreement; and schedule the related public hearing for the March 20, 2017 City Council meeting. MOTION ON THE FLOOR AS MOVED BY GOODMAN, SECONDED BY PAULY: Approve Resolution No. 2017-03, approving the Gilman Lofts (Three Tails) Development Agreement; and, direct the Finance Director to include $375,000 in a subsequent 2017 budget amendment, utilizing $75,000 from the Mitigation Fund and $300,000 from the General Fund.

CH2M 1100 112th Avenue NE Suite 500 Bellevue, Washington United States, 98004-5118 www.ch2m.com Keith Niven City of Issaquah Economic Development Director P.O. Box 1307 Issaquah, WA 98027 March 28, 2017 Subject: Gilman Blvd/Juniper St Intersection Dear Keith, Below is a summary of traffic operations at the Gilman/Juniper intersection that you had requested using the 2013 Concurrency model: Existing Conditions: Based on the 2013 model, the intersection is stop-controlled for only the Juniper and driveway legs of the intersection. Gilman is free flow, so those vehicles have no delay associated with the Juniper. The Juniper leg of the intersection operates at LOS D, with about 30 seconds of delay on average. The intersection processes about 1,800 vehicles during the p.m. peak hour. Existing Conditions, Signalized, No Other Improvements: If we were to drop a signal on that intersection with no other significant capacity improvements, the OVERALL intersection would operate at LOS B, with about 10 seconds of delay per vehicle experienced on average. The Juniper leg of the intersection would improve slightly to 25 seconds of delay and LOS C. Gilman Blvd. vehicles would now have to stop every once in a while, so the LOS would range between A and B with delays between 4 and 10 seconds depending on which movement (left, right, through). Still about 1800 vehicles traveling through the intersection during the p.m. peak hour. So not a huge improvement, but drivers would at least know they will eventually have an opportunity to exit SAFELY from Juniper. Existing Conditions, Signalized, 5-Leg Intersection: If a separate approach were created at the intersection for Rainier Blvd, as shown in the graphic below, the OVERALL intersection would operate at LOS C with about 20 seconds of delay per vehicle on average. However, some turn restrictions are assumed: no turns from Gilman Blvd onto Rainier Blvd, only to Juniper St, no right turn on red from Juniper St or Rainier Blvd. Juniper St and the Driveway would get a green light at the same time; therefore, left turns from each approach would have to yield to through vehicles. Rainier Blvd would have a separate green light phase. Future Conditions, No Signal: If we did nothing to the intersection, by 2030 the LOS would be so bad, our models won t even calculate the expected delay for the Juniper leg. Once it exceeds like a 150 seconds of delay, the model stops reporting the number because it s basically breakdown conditions, and very unpredictable. Also, by 2030, there are about 500 more vehicles trying to get through the intersections, so about 2,300 vehicles during the p.m. peak hour.
Page 2 March 23, 2017 Future Conditions, Signalized, No Other Improvements: By 2030, if a signal were installed there, the intersection would operate at LOS D overall, with about 54 seconds of delay. The Juniper leg of the intersection would operate at LOS D, with 46 seconds of delay, while eastbound Gilman Blvd. would operate at LOS E (77 seconds of delay) and westbound Gilman would operate at LOS D (38 seconds of delay). Future Conditions, Signalized, 5-Leg Intersection: By 2030, if a separate approach were created at the intersection for Rainier Blvd, as shown in the graphic above, the OVERALL intersection would operate at LOS E with about 66 seconds of delay per vehicle on average. Again, some turn restrictions are assumed: no turns from Gilman Blvd onto Rainier Blvd, only to Juniper St, no right turn on red from Juniper St or Rainier Blvd. Juniper St and the Driveway would get a green light at the same time; therefore, left turns from each approach would have to yield to through vehicles. Rainier Blvd would have a separate green light phase. The operations of the OVERALL intersection would improve to LOS D if the Juniper St leg of the intersection were to be widened at the intersection with a separate left turn pocket. Hope this helps you. If there is any other information you need/want, please let me know. Regards, CH2M Torsten Lienau Sr. Transporation Engineer
