Looking east, new sewer lines were installed behind the old apartment (aka barn).

The first buildings to be added to the grounds of the Washington Park Arboretum were begun in 1985, as defined in the Jones and Jones Master Plan Update for the Washington Park Arboretum. It took almost ten years for the building plans to be finalized and the funds to be raised. The public building was named the Donald B. Graham Visitors Center, and it housed offices, meeting spaces, public information space and a gift shop.
The Arboretum Foundation conducted the fund raising campaign, with the City of Seattle Parks Department supervising the project.
The original Works Progress Administration-constructed office/crew building was razed. A near-by large barn/apartment building was converted into the current crew headquarters and shop, with the upstairs apartment eventually being converted to office space. A new machine storage shed was added and the terrain of the land greatly changed.
The photographs taken March/April 1985 show sewer work and the building foundation and beginning walls of the storage shed. The new facilities were dedicated in 1986.

Succulent plants continue to be very popular amongst gardeners everywhere because of their unusual and architectural forms and thriving with very minimal watering. The Aeoniums are one of the most iconic of all succulents. Unfortunately, they are not hardy in the Pacific Northwest, but they are excellent container specimens that are actually pretty easy to overwinter if cared for properly indoors.
The key to success with any succulent is bright light, very well-drained soil and limited watering during the growing season. They respond to being fertilized on a regular basis during active growth (for us it’s June-September) and then as cold temperatures approach, they are dug up before the first frost and potted up and kept indoors where it can stay cool, but not freezing. Some growers overwinter them “bareroot” and will mist them occasionally so they don’t dry out. The more light you can give them during this pseudo-dormant period the better.
