RSL and LR 1 – Supersize! • The Grand Bargain was that Single Family became Multifamily and the development capacity “give” was generally one floor. • But in the process, multifamily development standards also grew. Details data source: URBAN DESIGN and NEIGHBORHOOD CHARACTER Study (Draft for Public Comment) on HALA website 1
RSL and LR 1 – Supersize! Today the goal is to: • Know what the new forms look like • Understand what is proposed to go onto a single family lot • Be prepared to give city comments on what you would want to see changed, development standards can be modified! 2
RSL – Current Forms • RSL purpose was “an area within an urban village that allows for the development of smaller detached homes that may be more affordable than available housing in single family zones” (DPD zoning chart “Seattle’s Single Family Residential Zones”) 3

What does this look like and what Affordable Housing might be constructed on site? Contrary to the city examples showing that 1 unit is the Performance requirement for all the RSL forms, it is actually two units or one 3 bedroom unit because that is specified in the MHA Residential Framework legislation See SMC 23. 58 C. 050. A. 2 of the MHA Residential Framework legislation 16
What does this look like and what Affordable Housing might be constructed on site? Magical note on the apartment slides – not a sure bet. • • • From: Staley, Brennon [mailto: Brennon. Staley@seattle. gov] Sent: Monday, March 06, 2017 9: 29 AM To: Barker, Cindi Subject: RE: MHA LR 1 proposed question You are correct that it doesn’t exist anywhere currently, so it would be a new provision that would have to be put in the Land Use Code. It would go in Chapter 23. 45, which contains the standards for Multifamily zones. 17
5, 000 – 6, 000 sq ft lot examples RSL Stacked Flats Lot coverage is not maximized RSL Tandem Housing Lot coverage close to maximized 18
10, 000 sq ft lot examples RSL Cottage Proposed The existing restriction is max 650 sf for each cottage, so you could have put more small units on this larger lot. The restriction is currently a limit of 12 units on any one lot. Lot coverage is not maximized Parking is provided in this example 19
10, 000 sq ft lot examples Low Rise 1 Apartments No Density Limit 5 unit max because of density limit, large units, but still not maximized to allowable FAR But could be higher density, as total allowed FAR is not used. 50 plus SEDU’s could go here @ 220 sq ft. 20
5, 000 sq ft lot examples Low Rise 1 Apartments No Density Limit 21
5, 000 sq ft lot examples Low Rise 1 Townhouses No Density Limit 22
Summary Points • The Bargain grew, not just 1 floor anymore. • To OPCD credit, considered RSL instead of pure Lowrise in the Single Family areas (as was specified in the Grand Bargain letter), and added 2 new forms. • RSL as it is now will essentially go away. • RSL up-zoned becomes what LR 1 is currently (but with half the FAR) • LR 1 up-zoned becomes what LR 2 is currently 23
Summary Points • City has not been clear about performance expectations, – 2 unit minimum unintended consequences • City is promoting performance requirements that are not confirmed, and could be eliminated based on other input. 24
Summary Points • The new development capacity that is proposed to added in the Urban Village Single Family zones also will increase the estimate of overall city growth from 70, 000 to more like 95, 000. • This number will be revealed in the Draft EIS. 25
