Hello Project Team,
Good news in that Clark Close of the City of Renton has initiated permit review for the May Creek/Ripley Lane Trestle
Rehabilitation project. With written response to the three (3) questions outlined below, Clark will be able to accept and
process the Shoreline Exemption application.
1) Please address how this work complies with the Trail Master Plan and EIS.
- KC Parks to generate a response to this question with specific references to pertinent documents related to
this type of work along the rail corridor.
2) Please provide additional information as to the impacts to the ground under and around the trestles and how
restoration will occur to these areas upon completion of construction. Also, include information on how staging will
occur during construction and any impacts associated to the surrounding area in the way of critical areas and/or the
shoreline.
- This question is addressed on pages C-2 and C-3 in the Erosion and Sediment Control Notes, Otak to prepare a
detailed response to this question.
Work under the bridges will be limited to personnel and hand equipment (ladders and hand tools (both bridges)
and grinding/welding (Ripley Lane only)) for repair of piles (both bridges) and repair of pile cap beams (Ripley
Lane only). Work at the ends of the bridges will include removal of existing rotten timber wing walls and end
walls, excavation to a depth of about 1’-2’ for replacing timber back walls and installing precast concrete block
wing walls, and grading for access to the tops of the bridges. Work from the top of the bridge will include
removal of existing fencing, timber walkway planks, steel railroad tracks and timber railroad ties. Debris
platforms can be placed under the bridges, attached to the bridge above the ground, to catch falling debris and
limit ground disturbance if required. Silt fence will be used to delineate areas where larger equipment may be
used (ends of bridges) and protect downhill areas, including creeks, from surface runoff and sedimentation.
Ground will be returned to existing grades. Disturbed areas can be seeded and/or planted as required.
2
3) Provide additional details on the transparency by removing the timbers and replacing them with concrete panels. You
had indicated in our last phone conversation that there would still be light trespass associated with the concrete panels,
but we would like you to demonstrate that this retrofit will exceed what is currently in place.
- In referencing the project drawings the existing width of the bridge deck above the stringers is 14’-4” +/- for
both May Creek and Ripley Lane, the new design calls for a 13’-8” bridge deck. The new narrower bridge deck
will allow more light to penetrate below. Otak to confirm this as a true statement accounting for the existing
railroad tie spacing and opaque walkways.
The existing bridge decking consists of 10’ width of timber railroad ties with varying gap between ties of 6”-7”
and about 4’-9” width of longitudinally oriented timber plank walkway with a solid non-slip surface. Gaps
between the railroad ties allow light to pass through. There are no gaps in the walkway, so light is unable to pass
through in that portion. The bridge is relatively narrow and light is able to penetrate completely under the bridge
from the sides of the bridge, depending on the time of day and season (surrounding deciduous trees).
The new bridge decking consists of 13’-0” wide precast concrete planks with about ¼” gap between the planks.
Because the total width of the new decking is less than total width of the existing decking (10’ + 4.75’ = 14.75’),
light penetrating from the sides will be lessened. The smaller gap between the new concrete planks compared to
the existing gap between timber railroad ties will limit light penetration between the planks.
Given the project schedule and our striving to get the construction completed prior to the Seahawks pre-season training
session, please prioritize and forward me the necessary responses accordingly in order to get this project permitted for
construction.
Thanks.

I have reduced the file size, and created a compressed folder for the application, however the file size is close to 24MB. I
tried sending this to you, but received the message back saying that the file limit is 15MB. I could try sending the packet to

Hi Clark,
Consistent with my voicemail left today, I’m writing to check in with the City of Renton on the implementation of the
May Creek and Ripley Lane Trestle Rehabilitation project along the Eastside Rail Corridor. The project documents are
being forwarded to King County Procurement for construction bid advertisement in the coming week. KC Procurement
has informed us that they will not open any bids unless all applicable permits have been issued. Per the attached
schedule, we are striving to get this project completed prior to the Seahawks training camp in mid-July to avoid potential
congestion issues as there is limited construction access at the Ripley Lane trestle location. People are already
informally using the trail corridor and we must ensure that the bridge rehabilitation work takes place prior to formally
opening up the trail for public use.
Otak (the project consultant of record) has been coordinating with Mona Davis in getting this project permitted,
potentially under an existing Temporary Use Permit issued for the rail removal project which is being completed at this
time. There is also the open question of how/if structural review of the proposed deck panels fits into the permitting
process as we have not received clarification. Otak has been ready to submit for the permit(s) for a number of weeks
now, but has not been able to schedule an intake appointment.
Please read through this e-mail chain for reference as to how the permitting issues have evolved with the City of Renton
to date.
6
In the interest of moving this project forward, KC Parks would formally request that an intake appointment be set up or
direction be given in the submission of the permit application package for review and approval.
Thank you.

Hi Chris…here is my latest correspondence with Bob. As you can see, I’ve asked for additional information to determine
if a revision to the existing TUP would be necessary, in addition to the shoreline exemption permit. I didn’t hear back
from Bob after my 11/28/17 e-mail.
We’ve determined that this work could possibly fall under the maintenance and repair of the existing Temporary Use
Permit issued for the rail removal, granted that you can demonstrate the following:
1) Please address how this work complies with the Trail Master Plan and EIS.
2) Please provide additional information as to the impacts to the ground under and around the trestles and how
restoration will occur to these areas upon completion of construction. Also, include information on how staging
will occur during construction and any impacts associated to the surrounding area in the way of critical areas
and/or the shoreline.
3) Provide additional details on the transparency by removing the timbers and replacing them with concrete
panels. You had indicated in our last phone conversation that there would still be light trespass associated with
the concrete panels, but we would like you to demonstrate that this retrofit will exceed what is currently in
place.
Once we receive this information, we can further analyze to determine if this does meet the criteria of a revision to the
existing TUP.
As for whether a building permit would be required, is the bridge being designed to AASHTO standards or the IBC? I’ve
copied our permit specialist, Steve Triplett, as well as the Development Review Engineer, Rohini Nair, to weigh in on the
building permit and the need for structural review. Is the County reviewing the structural calculations associated with
the bridge work? From my understanding, the work entailed replacing the planks and reinforcing the piles. Bob
indicated that the existing substructure will stay in place, but new decking would be installed after the tracks and ties
were removed. He was also proposing new fencing to be extended out to the farthest point of the bridge as opposed to
the narrow fenced walkway that’s in place now.
As we discussed, the Shoreline Exemption permit will take a couple of weeks to process.
Hope this helps…thanks!

Hi Bob…sorry for taking a bit to get back to you. We reviewed your proposed design and have some follow-up questions
we’d like further clarification on:
1) Would the new walking surface be expanded to be wider than the existing rail ties?
Bob D. 11-02-17: The new surface will be narrower than the wider of the existing ties. The existing surface
including the railroad tracks and walkway adjacent to the tracks is about 14 ft. wide. Railroad ties supporting only
the tracks are about 9 ft. wide. Roughly every 5th tie is about 16 ft. wide with the additional length to one side of
the tracks to support the walkway. The new decking will be either 12’ or 14’ wide (depending on rail connection
detail to be determined) and centered on the bridge.
2) Where you’re proposing to place new decking and chain link fencing on both bridges, would this be with the same
materials as removed? And would this be in the same location as removed?
Bob D. 11-02-17: The removed materials are timber (railroad ties and walkway planks) and steel (railroad tracks,
chain link fence and cable rail). New materials will be precast concrete (decking planks) and steel (chain link
fence). New decking will be place on the bridge and attached to the same timber support members (stringers).
However, the new decking will be centered over the bridge whereas the existing surface is offset (see attached
drawings).
This additional information would be helpful in determining what permits will be necessary and if this meets the scope
of maintenance and repair.
Thank you,

Mona,
Following up on our phone call from yesterday. Attached are portions of our preliminary design report (narrative portion
without appendices – plan sheets previously sent) that describe more about our project. I have also attached a few
select pages from the Eastside Rail Corridor Ecosystem Resource Inventory that I have been working from to estimate
potential impacts to sensitive areas: Wetland and two small streams at the southern portion of the Ripley Lane trestle
and May Creek itself (no wetland) at the May Creek trestle. The plans previously provided indicate all of the repairs
anticipated and you can note in our plans the following work in the vicinity of these sensitive areas:
· May Creek: Generally, it appears that bents 2-4 are inside the OHW. Work includes the following:
o Repair piles 2B, 2D and 3E
Repair Work/Equipment: steel banding using hand tools, ladders, people (no motorized
equipment)
o Removal of existing timber railroad ties, steel railroad tracks, timber walkway planks and chain link fence
above the creek.
Construction Work/Equipment: Small crane and/or excavator could be positioned adjacent to the
bridge as allowed to pick materials from the top of the bridge. Disturbed areas would be limited
to within the ERC right of way. Work may be completed from on top of the bridge if needed (not
preferred for ease/cost of construction but possible if necessary).
o Place new decking and chain link fence.
Construction Work/Equipment: Similar to removal work.
· Ripley Lane: Generally, it appears that bents 1-12 are within the wetland (WR11 per attached), bents 7-12
parallel the north-south stream (SR6 per attached) and the east-west stream (SR7 per attached) crosses
between bents 11 and 12.
o Repair pile 2E
Repair Work/Equipment: steel banding using hand tools, ladders, people (no motorized
equipment)
o Repair Cap Beam over Pile 9E
Repair Work/Equipment: weld steel plates to web of steel cap beam using hand tools, welder and
generator.
o Removal of existing timber railroad ties, steel railroad tracks, timber walkway planks and chain link fence
above the creek.
Construction Work/Equipment: Small crane and/or excavator could be positioned adjacent to the
bridge as allowed to pick materials from the top of the bridge. Disturbed areas would be limited

preferred for ease/cost of construction but possible if necessary).
o Place new decking and chain link fence.
Construction Work/Equipment: Similar to removal work.
As always, please let me know if you need anything. Have a good weekend!

Subject: RE: May Creek and Ripley Lane Trestles (Eastside Rail Corridor) for King Co. Parks
Jennifer,
I was contacted by Robert Bean at the County today. If I understand correctly, someone at the City contacted him and
there may have been some confusion about where to get project information (not sure of the details). At any rate, I just
wanted to put it out there that anyone at the City can feel free to give me a call or email for information. Robert Bean is
the Project Manager at the County and would be a good resource if you need overall ERC information beyond the May
Creek and Ripley Lane bridges. He and I are working closely to get the project finished but I have the latest info.
regarding the state of the May Creek and Ripley Lane bridge designs.
Robert also mentioned that we may only need a building permit because the bridges are inside the ERC right of way.
With that in mind, is there anyone else I should be in touch with or other information you will need?
Have a good weekend!
Thanks,
-Bob

Subject: May Creek and Ripley Lane Trestles (Eastside Rail Corridor) for King Co. Parks
Jennifer,
As discussed on the phone this afternoon, here is some information about the subject bridges we are working on for
King County Parks as part of the Eastside Rail Corridor. Please don’t hesitate to ask for more information should you
need it. We would like to provide you with the information needed to obtain permits as soon as possible.
In short, the work consists of the following:
· Minimal repairs to the bridges to bring them up to capacity for carrying the new trail
· Remove existing timber railroad ties, railroad tracks and existing walkway on the bridges
· Construct new, wider trail and associated rail/fence
Attached is a current set of preliminary drawings (Appendix D from our draft Preliminary Design Report. The full draft
report is available if needed).
Thanks,
-Bob
