At the June 5, 2019 Phase 1 Design Review, there were a few issues and questions which we would like
to address.
1. The use of Corten:
a. Will it drip and leave stains? We have looked at the design and what is directly below
the Corten panels. In most cases the bottom edge of the Corten panels was over
landscaping or planter boxes which will prevent rust stains from occurring. In a few
areas, there could have been an issue, so we have made changes to prevent this from
happening.
b. Is Corten OK for salty environments and fog? It turns out that there is a lot of literature
on this subject as Corten has failed in some applications. There are two conditions
where Corten can have problems:
i. Corrosive Atmospheres: ISO has conducted a worldwide atmospheric exposure
program known as ISO CORRAG and created a classification system for the
effect of atmospheric corrosivity on various metals including steel and
weathering steel which Corten is. Edmonds is in the second lowest corrosive
category (see ISO map) with a corrosion rate of less than 1 mm over a 100 year
period.

ii. Salinity is another concern for Corten: Corten is not recommended in
Subtropical locations or in Category S3 environments.
Edmonds is a Category S1/S2 environment.

2. The clerestory window on the light tower Building #1 facing Main Street: It was suggested that
these two windows should be the same size height rather than one taller than the other. This
change has been made.
3. Awnings: Several questions and concerns were raised about the awnings. It was not clear from
the drawings that the awnings will comply with the June 27, 2017 ADB Final Decision stated as a
condition of approval as follows: "AWNINGS ON THE 2ND AVENUE AND MAIN STREET FACADES SHALL
PROJECT A MINIMUM OF FOUR FEET FROM THE VERTICAL FACE OF THE BUILDING, VERTICAL FACE BEING EITHER
THE BUILDING FACADE OR PLANTERS BELOW." The drawings now show this condition more clearly for
the main building. Building #2 on 2nd Ave has considerably less length than Building #1, so a 3'
wide awning is proposed as that will be more in scale with the building.
4. Corner Terrace at 2nd & Main Street: It was suggested that a transparent material might be used
for the railing system of this terrace. This suggestion has been incorporated into the design.
Additionally, the planter box has been reduced in height such that the transparent portion will
be greater.
5. Elevation showing both buildings together along 2nd Ave: This is provided in the resubmittal
package and will be available to view electronically at the Phase 2 ADB hearing.
6. Main Building, 2nd Ave Windows: It was suggested by ADB that the windows of the main
building along 2" Ave extend lower to provide more visibility into the building from the
sidewalk. This has been done.
7. Design Guidelines Checklist: Our comments are added to the checklist.
