Staff report:
CITY OF ISSAQUAH DEVELOPMENT SERVICES DEPARTMENT DEVELOPMENT COMMISSION
2:12 Good evening and welcome to the April 6th meeting of the Issaquah Development Commission.
2:18 The agenda is, I hope most of you know, there was a last minute change
2:24 in the agenda, which I'll let Christopher Wright, the city staff, talk about.
2:31 And we will go on from there. So Christopher, do you want to explain what's
2:36 going on? Yes, thank you, Mr. Chair. As you mentioned the first item on the
2:40 agenda after the approval of minutes was to be a public hearing for the Rita
2:44 Rita Riva townhomes and that public hearing is being postponed to
2:51 a Yet to be termed date in the future As you know the Commission as
2:56 you know, we try to make sure that we have when we're working with the
2:59 applicants that we're all in the same boat and and and presenting kind of a
3:04 joint recommendation when we come to you some issues came up very late this afternoon
3:10 that we want to be able to work through with them before we come back
3:14 to you so and it was nothing real significant nothing real earth-shattering but
3:19 significant enough that like I said we want to take some time get some more
3:23 information before we come back to you so I would expect it will be back
3:28 sooner rather than later, but we don't have a date yet. Obviously we will need
3:32 to re-advertise, re-notice, re-publish once we establish that date, and we will do that.
3:39 But the other agenda item is the public hearing for Sunrise Assisted Living,
3:45 and that's what I know this group of people is here for. And so you
3:49 will be the decision makers tonight for that site development permit. And we have
3:56 Peter Rosen, a senior planner with the development services to do the presentation for staff.
4:02 And then we'll open it up for the applicant team to present as they see
4:07 fit. And then if there's any members of the public that wish to speak, they
4:11 could sign in on the sign-in sheet. And then we'll open it up for questions
4:17 from you and then ultimate decision. So those of you who have been through the
4:23 community conference, the format is pretty similar to that. The difference is that at the
4:28 conclusion of all the steps that Christopher just
4:33 underscored, there will be a formal going through basically a checklist
4:40 that will elicit the votes of each of the commission members on the Sunrise application.
4:44 All right. So with that, Commissioners, the first order of
4:50 business is the approval of minutes, and we have a number of them. So the
4:55 first one will involve the minutes from the meeting of March 2nd. That is
5:01 deferred to the next meeting, I see. So we'll go to the meeting minutes of
5:05 March 9th. Does anybody have any corrections or suggestions for that? If not,
5:14 Mr. Chair, I move we approve the minutes of the March 9th Development Commission meeting.
5:19 I second. Commission has been moved and seconded. Are there any comments, any
5:24 discussion? In that case, all those in favor of approval, as they
5:30 are, signify by saying aye. Aye. Opposed? All right. The minutes from
5:36 the meeting of March 9th are approved. The next is the meeting minutes from March
5:40 16th. Are there any suggestions, changes, additions,
5:46 deletions desired by any commissioner on that? If not, may we have a motion? I'd
5:52 make a motion that we approve the March 16th minute. Second. It's been moved and
5:56 seconded. Is there any discussion? In that case, all those in favor of approval signify
6:02 by saying aye. Aye. Motion carries unanimously. Minutes are approved.
6:08 So we will move now to the city presentation on the public hearing for Sunrise
6:13 Assisted Living by presentation by Peter Rosen from the Environmental Center. Good evening.
6:22 Just a little background that this project was approved by the Development Commission in 2007.
6:30 I think that some of you might have been on the Development Commission at that
6:34 point. I realize you might not remember back that far though, So the
6:40 site development permits are valid for three years and it
6:45 expired because the applicant didn't submit building permits within that time. So
6:52 this proposal's been, the project's been scaled back a little bit, partly due to
6:58 some new codes that were adopted since the project was originally went through
7:07 the development commission and the new codes that apply are that the
7:13 stream buffer stream buffers that are associated with steep slopes can no longer be reduced
7:18 and there's also tree retention requirements that weren't in the code at the time.
7:26 Just a little bit on the staff report, the organization of the staff report. There's
7:30 first Part of the staff report goes through the development and
7:36 design standards, chapter 1807. There's also a section of the code that's
7:42 specific to assisted living facilities, and the staff report goes through
7:48 that, as well as sections on environmental review, access street improvements, parking,
7:53 utilities, tree retention. And then there's There's the
7:59 design criteria checklist, which are the green sheets, and I understand that that
8:05 may have inadvertently not been included in the packet, but that's Appendix A, and
8:12 I do have a copy that I'll be able to project on the screen when
8:17 we get there. There's Appendix B, which is a, there are two
8:23 administrative adjustments of standards, AASs, One is for the building setback
8:29 from the stream buffer. There's a 15 foot building setback required from the stream
8:35 buffer and there's a proposal to reduce a portion of that. And there's also an
8:39 administrative adjustment of standards for the building height, which I'll also discuss.
8:45 There's exhibits that were included with the
8:51 staff report and the staff report the architectural civil landscape plans, the building materials
8:57 board, SEPA determination, river and streams board minutes, traffic concurrency,
9:03 public comment letters were all included as exhibits. I do want to go back to
9:09 the AASs for a second here, the administrative adjustment standards. Those are administrative
9:14 decisions. Sometimes they get consolidated with the SDP permit.
9:23 But the code, per the code, it's
9:29 up to the applicant of whether it gets consolidated. And we did have an email
9:33 that the applicant requested that it not be consolidated.
9:39 So the exhibits are written for those AASs,
9:45 but the decision on those has been done administratively. So just
9:51 to clarify that. At the back of the staff report are recommended conditions and there's
9:57 basically three sections. There's the SEPA mitigation measures, SDP conditions, and then
10:03 construction conditions. So
10:09 the proposal is for a site development permit for the construction of an assisted living
10:14 facility. The new facility would include 82 units, The building's
10:20 approximately 96,500 square feet, five stories. You'll notice that
10:26 there's not a lot of parking shown on the site plan because the parking is
10:32 primarily below the building. There's 50 parking spaces below the building and there's
10:38 two surface stalls.
10:45 Site location. The
10:51 site is located on Issaquah Falls City Road, very close to the intersection with Black
10:56 Nugget Road. You'll see here that it's also at the intersection with
11:02 Black Nugget Road, it's close to Highlands Drive. Here's the Issaquah Highlands, Overdale Park.
11:09 There is a steep ravine along the east and south part of the site, which
11:14 is the North Fork of Issaquah Creek. Then
11:20 obviously there's I-90 down to the south of the
11:26 site. So the site is currently
11:32 undeveloped and heavily forested. As the figure shows,
11:38 the site has split zoning. It's multifamily medium and single family
11:44 small lot. The use is allowed in both of the zones. In terms of the
11:49 development standards, what the code states is that you use the development
11:55 standards that compose the majority of the total lot size, and so the
12:00 multifamily medium is slightly larger than the single family small lot, and so
12:07 it's those development standards of the multifamily medium zone that apply, and actually
12:13 they're very similar development standards between the two zones. Not a big difference there.
12:19 I want to point out that, again, the North Fork of Issaquah
12:25 Creek borders the east and south of the site, and so on the other side
12:30 of that wooded ravine is single-family development. I believe it's
12:35 single-family estates is the zoning. To the south of the site is Lakeside
12:41 Industries, and the zoning there is is Urban Village
12:46 Lakeside. There's a development agreement for future development of Lakeside Industries
12:52 property after the gravel mining operation phases out.
12:59 Across Issaquah Falls City Road from the site is multifamily development.
13:06 Just a couple of views. This one is a
13:12 view of the site as you're coming up Issaquah Falls City Road and this is
13:18 a view of the site as you're going down Issaquah Falls City Road. You can
13:22 see that it is currently heavily forested.
13:28 This is coming down Issaquah Falls City Road when you're north
13:34 of the intersection with Black Nugget and this is coming up Issaquah Falls City Road
13:40 and it shows the intersection of Black Nugget Road as well.
13:47 I just wanted to discuss some of the critical areas and buffers because that drives
13:52 a lot of the project in terms of the developable portion of the site. The
13:57 site is very constrained by critical areas. There's a very
14:03 steep slope area on the east portion of the property. Again, there's,
14:09 at the bottom of that ravine is the North Fork of Issaquah Creek. The North
14:13 Fork of Issaquah Creek is a class two stream with salmonids, so there's a 100
14:18 foot buffer from the North Fork. And the steep slopes,
14:26 the code requires a 50 foot buffer. That can be reduced to a minimum of
14:32 10 feet. So on this figure, the orange line
14:38 here is the steep slope buffer, and what you could see is that in the
14:43 portion of the site to the north, the slopes are over 60%
14:50 grade, and the Geotech recommended a 20-foot buffer in that case,
14:56 and recommended a 10-foot buffer for the remaining, though in
15:01 this portion of the site it's also 20 feet. I do want to mention that
15:07 The buffer reduction in the geotechnical report went through a peer review by Golder Associates
15:13 who concurred that there wouldn't be issues with slope stability
15:19 with the steep slope buffer reduction.
15:26 Note at the south end of the site, there's an observation
15:32 deck and that projects into the steep slope reduced buffer area
15:38 so there is a SEPA condition that requires that the observation deck
15:44 doesn't encroach into the steep slope area and in the building setback area
15:50 the observation deck would have to be pretty close to
15:56 on grade in terms of 30 inches or less so that it's
16:03 not considered a structure in the building setback.
16:13 In terms of the stream buffer, that's the green line here,
16:19 and you can see the building setback is 15 feet offset from the stream buffer.
16:25 The code doesn't allow the stream buffer to be reduced wherein it's associated with steep
16:31 slopes. And as I mentioned previously, there's an
16:36 administrative adjustment of standards to reduce the building setback since the
16:42 stream buffer can't be reduced through buffer averaging or through the other provisions of the
16:47 code. That would reduce the building setback to a minimum of five feet.
16:54 And that just is in this particular area. Elsewhere, the
17:00 15-foot building setback is met. So the reduction is approximately a third
17:06 of the linear feet of the building area.
17:12 So the total site area is 2.32 acres, but with all the
17:18 critical areas, the developable area, the site is limited to 1.09 acres. The
17:31 On the east side of the building is in the stream buffer. The
17:36 observation decks and trails are permitted use in the buffer, but they need to be
17:42 buffer averaged, and the applicant has proposed, has taken the
17:48 total area of the encroachments into the stream buffer and has added additional buffer area
17:54 to the south. And I could show that
17:59 on a separate figure in just a minute. Mr.
18:05 Chair, just a quick question. Peter, the plans we have, the site plan is
18:12 different than this? So is this a more recent version you're showing us?
18:19 There was a plan sheet for buffer averaging for the buffers that was in the
18:25 plan set, in the architectural plans. This is, what we have
18:30 is different in terms of the deck that's
18:36 shown. Okay. We did, the applicant modified
18:43 some of the plans because it wasn't entirely clear of
18:50 the 20 foot buffer at the north end of the site, so this is, and
18:54 this may be a new figure that wasn't included. in the packet and I I
18:58 use this one because it it shows more clearly the steep slope buffer where it's
19:03 20 feet as opposed to 10 feet and it was just the clearest drawing to
19:08 highlight the the buffer line so it it um this wasn't part of this is
19:13 the more those deck areas and so forth they're the revised versions of them then
19:17 from what we have I believe that I don't think the um the
19:23 deck areas changed from what was shown on on the plans that we have. Yeah,
19:27 I think so. Like in here in the package and what's in here. I could
19:32 go to the plan sheets if you. Sure. If you go to A2. Yeah.
19:45 Okay, so. You can see that's a 90 degree angle on that.
19:54 Okay, so that compared to and it actually extends into the 40%
20:00 slope. You can see there's an angled...
20:08 It looks like to stay out of that. It may have been slightly modified. I'll
20:13 let the applicant address that. I know that... So what occurred here is that with
20:17 the SEPA review, there was a condition, as I described, that
20:24 the decks couldn't go into the steep slope area or into the steep slope reduced
20:29 buffer, the 10-foot buffer. And so the applicant may have
20:35 modified the drawing based on that condition. And Peter, that's
20:41 what we've got in our packet there. This is the illustration. This is the A2,
20:45 right? Yes, this is A2. So the difference is between the one that we have
20:51 in our packet that Commissioner Morgan pointed out. Could you just for the record here,
20:57 just run the cursor over and tell us what the differences are. So it's not
21:01 highlighted on this drawing, but this line is the 10-foot steep slope buffer, so the
21:07 difference is you could see that the observation decks
21:13 intruded not only into the steep slope buffer, but partly into the steep slope area
21:18 itself. So, I think it's been modified some
21:24 that it still goes into the, it still projects
21:30 into the steep slope
21:35 buffer some, but not as much, and it doesn't extend into the steep slope area
21:40 itself. Does that address your concern, Commissioner?
21:46 Okay. And in terms of, I wanted to,
21:54 also show that here is the buffer averaging that's shown. So
22:01 as I mentioned, trails and observation decks on grade are
22:07 allowed within stream buffers, but you need to buffer average, so you need to add
22:13 an area equal to the encroachment outside of the buffer. So
22:19 this figure shows the The patterned area is the encroachment into
22:25 the buffer, and then this is the added buffer area at a one-to-one ratio to
22:30 the encroachment.
22:45 In terms of the development standards, I mentioned that it's the multifamily medium zone that
22:50 applies because it's just slightly over 50% of the site area. So the
22:57 staff report goes through the development standards, the land use code development standards in 1807,
23:05 and the proposal meets the development standards for setbacks, for parking, for
23:11 impervious pervious surface coverage and tree retention.
23:18 I also mentioned there's a specific section on assisted living facilities criteria,
23:25 and the proposal meets that criteria as described in the staff report.
23:31 And there's also the design criteria
23:37 checklist, commonly known as the green sheets, and that was attached
23:43 as Appendix A to the staff report. and the building design and landscape
23:49 also meets that criteria. I mentioned that there's a administrative adjustment
23:55 for the building height. The code allows a 40 foot base
24:01 building height and that can be increased to 50 feet. There's
24:07 basically two provisions that have to be met or one of the two provisions have
24:12 to be met to increase the building height. from 40 to 50 feet, either the
24:17 upper stories above the base height need to be reduced by 25% or the pervious
24:22 surface area needs to be increased by 10% over the zoning
24:28 requirements. So the zone requires 50% pervious area
24:34 on this site and what's proposed is 64%. So that's how they
24:40 met the criteria for the building height. administrative adjustment.
24:50 Also, just wanted to mention in terms of the parking, the standard is that it
24:55 is one per two units and one per employee. And
25:02 so the proposal meets the parking standards. There's 52 parking spaces
25:08 provided, 50 under the building and two on the surface.
25:15 In terms of circulation, there's two access
25:20 points to the project site. An access off, the driveway
25:26 access off of Issaquah Falls City Road and a site access off of Black Nugget
25:31 Road. Both of these site accesses will be limited to right in, right
25:37 out only. That's due to the road grades to the to
25:43 speed and sight distance and on Black Nugget Road due to the proximity to the
25:49 intersection. For pedestrian circulation, there's
25:55 a crosswalk that goes across the main drive and
26:01 there's a condition in the staff report recommended condition that that crosswalk use distinct
26:07 materials like pavers, to distinguish it from the road.
26:14 So the crosswalk leads from the building entry to a sidewalk, and so
26:20 there's a sidewalk that would go to the intersection with
26:26 Black Nugget Road, and then there's sidewalk on Black Nugget Road.
26:32 There's not a sidewalk that would go to the south of this site along Issaquah
26:37 Falls City Road, and the reason for that is because the Lakeside Industries property,
26:43 which is to the south. There's not a sidewalk that's planned adjacent to the Lakeside
26:49 property, so a sidewalk to the south would not provide a connection
26:55 on this site. This figure is
27:01 pretty hard to read, so I'll probably just go to the landscape plan to show
27:05 it, but in terms of tree retention, The clouded areas
27:11 are where they are retaining the trees. The code requires 25%
27:17 of the total caliber of trees outside of critical areas and buffers to be
27:23 retained. The code also allows that to be reduced by up to 50%
27:29 and there's some specific criteria for reducing the tree retention. One of the
27:35 criteria is the modifications necessary due to the characteristics of the site, the size and
27:41 shape of the property and that meeting the tree retention would
27:46 jeopardize reasonable use of the site. As I mentioned, it's a very constrained site due
27:51 to the critical areas. The critical areas don't count toward the tree retention. And so
27:58 it meets that criteria of the site. the characteristics of the property.
28:06 Also one of the criteria is that it's necessary due to required ingress and egress.
28:12 And as we saw on this figure, the drive is connected between the two
28:18 access points and that's another reason that some of the existing trees
28:24 couldn't be retained. The applicant is proposing replacement
28:30 trees, 29 mitigation trees. Replacement trees are not required by the
28:36 code if you don't meet the retention, but they are providing 29
28:42 replacement trees, as well as in the area to the south of the building,
28:48 there'd be invasive plant removal and then enhancement with
28:54 native plants in the stream buffer.
29:02 In terms of the building design, the assisted living
29:07 facilities criteria has been met. That addresses barrier free standards. There's
29:13 community space, both indoor and outdoor community space that's required.
29:20 It meets those provisions. It meets the parking is also addressed in the assisted
29:25 living facilities criteria. as well as there's criteria in that section for building
29:31 modulation and roofline variation which are also
29:37 addressed in the green sheets in the design checklist. And the design checklist
29:42 criteria also addresses the building modulation and roofline variation
29:48 and the variation of building materials. I
29:54 do have the building materials board is an exhibit that
30:00 was included, and I could pull that up.
30:07 But I think I'll just leave the details of the building design to the applicant
30:12 to go over. There is a
30:18 condition, recommended condition, that's also addressed in the design criteria of screening
30:26 ground and rooftop mechanical equipment, so that would be reviewed with construction
30:32 plans. That's the end of what I have right
30:38 now. There aren't questions or if you want to. I think
30:44 probably what we'll do is if there are specific questions
30:50 of staff on his presentation, we'll go ahead and do it. do it now since
30:55 we don't have two meetings or two different agenda items tonight. So if you do,
31:01 we can always come back to them later on in the period where the commissioners
31:06 get to see clarification and so on. But if anybody has a question now from
31:11 Mr. Rosen, you'll be fine. MR. Yeah.
31:17 Can you talk a little bit about the frontage condition, landscaping,
31:24 what's happening there because we have a road profile there that's, if you include the
31:28 turn lanes, I think it's like six lanes wide. And we're adding another road right
31:34 adjacent to it. And so now we have a sidewalk and it looks like a
31:37 very narrow landscape strip in there. And so can you talk a little bit about
31:43 what's the condition we're going to have and what the code requirements are for that?
31:46 Yes, so there is a landscape strip that is between the
31:52 road and the sidewalk, and it's a five-foot landscape strip, which is what is required
31:57 by the code. So just five feet between the sidewalk and the roadway? And
32:02 then street trees? Let me go to the landscape plan. Might
32:09 be a better choice here.
32:24 It actually, it may be a 10, I think it's a 10-foot landscape strip. Landscape,
32:28 landscape, okay. So you have the landscape strip
32:34 between the sidewalk and the road. And what? With street trees. What
32:39 are the street tree species? Yes, so the street trees
32:47 are. They're just deciduous or conifers? They're deciduous. I'm sorry. I. All
32:53 right, that's what it was. But they're deciduous street trees. I
32:59 know I had a discussion with the landscape architect about the choice of the street
33:03 trees there. But it's a little hard. I can expand the drawing to
33:09 read it. We can get that. I'm going to go to the applicant. Are there
33:12 any other questions of Mr. Rosen? I just have a quick question. That's actually the
33:17 slide that I would have you reference, as we don't have that one in our
33:23 packet, at least I don't. So my question is, what kind of
33:28 trees are going to be replaced? So what is the
33:34 applicant using to replace the trees that are being removed? So in the...
33:43 On the east side of the building is basically all stream buffer. And so all
33:49 the plantings are required to be native species. If the question is about
33:55 the replacement trees,
34:01 these are the added mitigation trees. And so there's
34:07 vine maple and red cedar and Douglas fir. the
34:12 replacement trees. Thank you. Mr. Seiberg, do you have a
34:18 question? I do.
34:25 The steep nature of that slope is a concern, and I don't really
34:31 understand what a tight line stormwater down the steep
34:36 slope means. And exactly, are they gonna have a retention pond with a pipe going
34:42 somewhere or? Right. So there's, I could pull up the civil
34:48 plans here. There is a stormwater vault and
34:54 the discharge, there were,
35:02 so there's a stormwater vault and so there were two options. that were shown for
35:07 the discharge from the stormwater vault. One was a dispersion trench, but
35:13 given the nature of the steep slopes, and this is also a high erosion area,
35:20 there were concerns about releasing the stormwater at the top of the slope. And so
35:26 tight lining entails that it would basically be piped
35:32 down the steep slope. To where? Bottom of the slope
35:38 and then it just percolates somewhere? Well,
35:44 there's a pad where the pipe ends. And so
35:50 the details of that haven't been worked out yet. And I'll let the
35:55 applicants civil discuss that further. But
36:02 there's a SEPA condition regarding that the that the discharge be tight
36:07 lined down the slope to avoid the erosion and slope stability. I know, it's a
36:13 big paragraph in the conditions and I just wanted to kind of explain. So
36:19 the Geotech Golder Associates, the peer review, had some very
36:25 specific conditions that they recommended for the stormwater tight
36:31 line because it hadn't been designed yet. And so the conditions,
36:37 those would be reviewed with the construction permits for the timeline. Okay.
36:44 Thank you. Any other questions for Mr. Rosen? The commission? All right. Thank you, sir.
36:50 We'll go now to the applicant. By the way, before we go any further,
36:56 lest I forget, if there are members of the public that do want to speak
37:00 when it comes to that segment, which is the next one, We would ask that
37:03 you sign the sheet here and give your name and your address on the
37:10 sign-in sheet that's there on the table, if you care to speak. Good evening. My
37:15 name is Todd Wyatt. I'm an attorney at Carson Knoll here in Issaquah. I represent
37:20 Sunrise in this. I want to thank the members of the commission as well as
37:24 city staff for their cooperation to date in getting this project going. Before
37:30 I make any comments, I want to introduce, we've brought a number of people here,
37:33 part of our team today, to help answer any questions you may have, and I
37:36 want to introduce them to the members of the commission. First is the Vice President
37:41 of Investments and Development at Sunrise. His name is Jerry Liang. He came out here
37:45 from Virginia to speak to you tonight. Also is James Brown from Wattenberger Architects
37:51 in Bellevue. James is the principal architect on this project. Mark Keller from Biler
37:57 Construction here in Issaquah. He's our civil engineer on this project. Kurt
38:03 Gonberg, did I pronounce it right, Kurt, is from Transpo Group in Kirkland. They did
38:08 the traffic engineering for this. Brian Beeman from Icicle Creek
38:13 Engineers was the geotech engineer on this project. And is Tom
38:19 Deming here? There's Tom. Tom Deming, he's from Habitat Technologies and did the
38:25 critical area assessments. That's the team, and we are here to answer your questions, but
38:31 before we do that, Jerry Liang is gonna speak to you for a few minutes
38:36 about Sunrise, who we are, and what kind of services Sunrise offers, and then James
38:42 Brown is going to go over with you some of the architectural details of the
38:47 project and answer those questions. Before we do that, though, I do need to make
38:51 two, because this is a quasi-judicial thing, I need to make two comments just to
38:55 get them on the administrator.
