ISSUE Should the City Council consider a Development Agreement with Homestead Community Land Trust to develop an affordable housing project comprised of 18 compact single-family homes on the undeveloped portion of the Riverton Park United Methodist Church property? BACKGROUND Homestead Community Land Trust has proposed to develop 18 highly energy efficient, affordable, compact single-family homes in the Cascade View neighborhood of Tukwila. The project is located at the intersection of Military Road S. and S. 140th St on the undeveloped portion of the Riverton Park United Methodist Church property. See Attachment A for the vicinity map. Homestead Community Land Trust was founded in 1992 and has created a portfolio of 214 permanently affordable homes for ownership. It partners with homeowners who make 50 to 80% of area median income to create and preserve opportunities for homeownership. What is a community land trust (CLT)? A community land trust (CLT) is a private, nonprofit organization created to acquire and hold land for the benefit of a community and provide secure affordable access to land and housing for community residents. How does Homestead work with homeowners? Homestead secures public and private grants and donations to lower the cost to the buyer. The buyer pays for and owns the home (structure and improvements) on the land. Homestead continues to own the land under the structure and leases it for a small monthly fee. A resale formula built into the ground lease keeps homes affordable for subsequent buyers. See Attachment B for more background on Homestead. DISCUSSION What is the proposed project? The proposal is to build 18 compact single-family homes that range in size from 1385 to 1500 square feet on a 1.43 -acre lot. Phase 1 will include 11 homes and Phase 2 will include remaining 7 homes. The proposal includes a total of 32 onsite parking spaces and 10 shared spaces on the church property. With three and four bedrooms these homes will serve larger 7 INFORMATIONAL MEMO Page 2 families not served by most rental housing. In addition to providing affordable housing the project intends to build highly energy efficient homes and achieve higher environmental outcomes than required by building code standards including use of solar panels, rainwater harvesting and net zero energy principles. See Attachment C and D for project description and plans. Why is a Development Agreement needed for this development? Homestead would like the City to enter into a development agreement that would modify the City's development standards to provide flexibility in the site design. The current zoning requires 6500 square feet minimum lot size. However, there is no requirement for common open space for any single-family development. The City's housing options program that adopted different standards for cottages and compact single-family homes has expired. In addition to the lot size the standard parking requirements in the Low Density Zone (LDR) require 2 parking spaces for a 3 bedroom home and 3 spaces for a four bedroom home. The proposal is to have 32 on site spaces and 10 shared spaces on the Church property. In addition to the development standards the city may want to include a public hearing design review for the proposal to address any design concerns. Pursuant to Tukwila Municipal Code (TMC) 18.86, the City has authority to establish development standards and other provisions that would apply to a site-specific development and vest the project. If this project is built, then it could be a demonstration project that could inform the city in the preparation of a future housing options program that adopts development standards for cottages and compact single family homes. What type of public outreach is planned for this development? Depending on the outcome of the Committee decision, Homestead is planning on hosting a public meeting in early April 2018, and prior to the City Council public hearing. A notice to all property owners and residents within 1000 feet of the subject site could be provided. Similar notice would be provided for the City Council public hearing. In addition, the notice of hearing could be posted on site, published in the City's official newspaper, included in the legal notices section on the City's website. Additionally, staff is seeking direction from the Committee on any other avenues that should be used for the public outreach efforts. FINANCIAL IMPACT None RECOMMENDATION The Committee is being asked to authorize staff to move forward with discussions with Homestead to enter into a development agreement. Staff will then come back to the Committee on April 10th, 2018, with a draft development agreement and an ordinance. At that time the Committee will decide whether to forward it to the Committee of the Whole for discussion and a public hearing on April 23rd, 2018. ATTACHMENTS A. Vicinity Map B.

Teachers, first -responders, corporate employees, health care workers and others who keep our communities vital, will have an affordable housing payment that builds equity, and support from Homestead's ongoing stewardship program. We subsidize the price of homes to make them affordable at first purchase. Owners sell the home at the time of their choosing at an affordable price to the next buyer. This model preserves income diversity and will prevent displacement as this neighborhood grows.

The project will be developed on land at the intersection of Military Road S. and S. 140th St, purchased from the Riverton Park United Methodist Church. Homes will be priced affordably for households whose income is less than 80% of area median income as defined by the US Department of Housing and Urban Development for King County. These homes will provide owners with a high quality residence, a fixed and affordable housing payment that allows the owners to build financial equity, and all the social benefits of living in an owned home, which include better student academic outcomes, improved health and mental health, and greater connection to community. The first phase of the development will create 11 highly energy efficient homes, with high levels of insulation, and the use of photovoltaic solar panels and Net Zero energy principles. The current site plan features on-site food production (pea patch) and integration of fruit -bearing trees within the drought - resistant landscaping. The project intends to achieve higher environmental outcomes than required by building code standards including rainwater harvesting, and rain gardens. The project is designed to fit into the single family nature of the neighborhood. In doing so Homestead will provide mitigation to the parking area with landscaping, planting strips, fencing and covered parking. The project will include a total of 42 parking spaces, 32 on site and 10 provided in collaboration with the church. The community land trust model of ownership assures that the public's investment to make these homes affordable stays with each home resale after resale, keeping them similarly affordable to all subsequent buyers. As a result, Riverton Cascade homes will remain affordable to generations of owners preventing further displacement of modest -income people as the neighborhood grows and revitalizes. Homestead remain in relationship with the homes and homeowners to preserve affordability and promote homeowner success. Homestead educates individual families at the time of purchase and post -purchase about the proper use and maintenance of their home. We provide support and referral in times of financial distress. We work with homeowners associations to support their collective maintenance and stewardship of their common interests. Planning for the housing units has been integrated with plans to improve the church's Food Bank interior design and outside traffic flow, exterior improvements to the Church and Church properties, redesign of the Church kitchen, and energy efficiency of the Church and Church properties. Community outreach for the development has included participation in the Congress for New Urbanism "TIB Neighborhood Rising" Legacy project, February 2017, research on local priorities for food production, and coordination with Riverton Park UMC and the associated Tukwila Food Pantry. A neighborhood outreach meeting for those in the immediate vicinity of the development is planned for early April 2018. Founded in 1992, Homestead has 214 homes in its portfolio which have put affordable homeownership within reach of 243 income -qualified families. 412 Maynard Avenue South, Ste. 201. • Seattle, WA 98104 • (206) 323-1227 • infoC'HomesteadCLT.org www.HomesteadCLT.org 23 24 HOMESTEAD Community Land Trust MARCH 2018 RIVERTON CASCADE HOMEOWNERSHIP PROJECT SAGE' RLC TI TNU RcA J91.1: aNPROJECT OVERVIEW Homestead Community Land Trust, in coordination with Riverton Park United Methodist Church, proposes to redevelop a portion of the church parking lot and gardens into 18 cottage -style single family homes. The property is located an the NE corner of the intersection of Military Road S & S 140th St in Tukwila, Washington. Located on the Military Road bus line and within a mile of the Tukwila International Boulevard Light Rail Station, Riverton Cascade will provide affordable family homes at a subsidized price of 5180,000 to 5235,000 approx,. The Riverton Cascade project will serve Homestead's target population of home buyers who are up to 80% area median income. Through our Community Land Trust, these homes will be affordable to the first buyer and will remain affordable to all subsequent low -to moderate -income buyers that own the home. The proposed project will be completed in two phases. The initial phase builds the first 11 homes. The 2 -story homes vary from 3-4 bedrooms with emphasis on larger family -size units, This project has been awarded funding from Dept. of Commerce to develop an Ultra Efficient pilot program. The project will incorporate performance building envelopes into the design of the houses which will feature high levels of insulation and low air leakage. This will be coupled with desired use of photovoltaic solar panels and Net Zero energy principles. In addition, the current site plan will feature on-site food production (pea patch) and integration of fruit -bearing trees within the drought -resistant landscaping. Development will minimize hard scape and other impervious surfaces through site design, and will use bio -retention and conveyance for treatment of storm water to the maximum extent feasible. We are proposing a higher density project with lot sizes that are smaller than what is allowed by the underlying zoning. Funding commitments from the State of Washington and King County will allow construction of Phase 1. Other funding sources include grants and loans from the U.S. Department of Housing and Urban Development's HOME program through King County, as well as Private Lenders and Investors. Other partners with Homestead Community Land Trusl on this project include Parkview Services and longtime Funding Partner Community Frameworks. MASTER PLAN ENVISIONING Homestead Community Land Trust & SAGE will be assisting Riverton Park United Methodist Church in the overall Master Plan of the Campus, such as improvement to the food bank, Church's Community Kitchen, Community Garden, Landscaping and Church Housing. ABOUT HOMESTEAD Homestead Community Land Trust stewards a portfolio of 214 high-quality, affordable, owner - occupied homes and provides counseling and support services to ensure homeowner success. They have had 29 resales so these homes have provided a total of 241 households with the opportunity for affordable homeownership. Homestead's growing stock of affordable homes will provide homeownership opportunities for thousands of Low -to -Moderate Income households in the years to come.
