Request for Proposal

55th Avenue S. Stormwater Study for Water Quality Improvements for Kubota Garden and Mapes Creek

Previous Submittal Date: August 19, 2020  

Note to all potential submitters: The Request for Proposals (RFP) is modified as set forth in this Addendum. The original RFP Documents and any previously issued addenda remain in full force and effect, except as modified by this Addendum, which is hereby made part of the RFP. Respondent shall take this Addendum into consideration when preparing and submitting its Proposal.  

Proposal Submittal Deadline The Proposal submittal deadline has been changed as noted herein, and modifies the deadline stated in the RFP. The revised proposal submittal deadline is 5:00 pm on August 21, 2020.  

Questions and clarifications The following questions and answers are provided as a matter of information to clarify issues raised about the RFP during the optional pre-submittal webinar held on August 12, 2020.

 1.      How would the Advisory Team like to have the consultant teams assembled?

A.      This is up to each consultant.  It is important for the applicants to meet the qualifications described in the RFP.

2.      What time is the proposal due?

A.      Note: Addendum states the revised proposal submittal deadline is 5:00 pm on August 21, 2020.

3.      The RFP identifies a total budget of $108K and identifies three phases for this project.

A.      The $108K covers both phases 1 and 2.  Phase 3 is funded separately through Seattle Parks and Recreation's Major Parks Challenge Fund. 

4.      Will the permit ready documents get wrapped into construction? 

A. Phase 1 and 2 will result in permit ready, 90% construction document plans.  Funding has not yet  been identified for construction.

5.      What type of existing survey information is available?

A.      This is mostly City owned property, and City GIS data will be available for use. Seattle Parks and Recreation has survey data for many areas within Kubota Garden including the parking lot.

6.      If there are areas that need to be surveyed where data does not already exist, could this be covered outside of the consultant fee.

A.      Yes.  And there is new survey available because of ongoing projects in the Kubota Gardens.

7.      Will Phase 2 include an estimated cost of construction?

A.      Yes, this estimate should be included in the 90% construction documents developed in Phase 2.  

8.      One of the criteria is similar projects (20 points).  As stated in the RFP I was including subconsultant project experience in the firm profile section (15 points). For the 20 point section with reference information, I have two specific questions:

a.       Can we highlight a project from a subconsultant, or should they be for the prime only?

b.      Are we limited to 3 projects, or is that the minimum?

A.    Three projects are a minimum. Similar projects and there are no requirements that the project must be completed by the prime. Choose the most applicable project(s) to highlight. Consider the team and the distribution of the work

9.      Can you repeat where maps and background information will be posted?

A.      On the Seattle Parks and Recreation website, along with the Kubota Gardens improvement project. This is the same location where the RFP was posted.

Request for Proposal

55th Avenue S. Stormwater Study for Water Quality Improvements for Kubota Garden and Mapes Creek

Project Description
The Kubota Garden Foundation (KGF) seeks proposals from qualified design teams to conduct a stormwater study to analyze current flow patterns and drainage issues and develop design options to treat and convey stormwater from the hillside along 55th Ave S. into the ponds of Kubota Garden which are part of Mapes Creek. The preferred design will be developed through construction documents.  


Kubota Garden Master Plan Update

Kubota Garden is a public American-Japanese garden in South Seattle that started as a beautiful vision of Fujitaro Kubota, a Japanese emigrant. You are invited to learn more about Fujitaro's story.

Thank you to everyone who provided input on for the Master Plan Update and participated in the Master Plan Update process. See information available below. Kubota Garden has seen many changes in the years since its Master Plan was put in place. Consequently, a Master Plan Update is being developed to guide garden development programs and maintenance over the next 20 to 30 years. Master Plan Update will preserve the garden and passive recreation use, while defining future improvements, such as buildings, parking, pathways, and security, as well as assessment and recommendations for protecting the garden's existing creek, vegetation and wildlife. The design team of Jones & Jones Architects and Landscape Architects and Hoshide Wanzer Architects used public input as they developed ideas for the garden.

Thank you, Seattle. The Kubota Garden Perimeter Wall is complete!

A community-initiated project, the Seattle Park District Major Projects Challenge Fund provided matched funding for design/construction of an expansion to the existing ornamental wall. The project was completed in fall of 2019.

Why is this wall being built?

  • The ornamental wall currently being constructed continues the wall built (primarily by volunteers) over the course of the past 15 years. When complete, the current construction will be the same height and have the same beautiful roof and stucco finish as the wall of the entry gate. The additional wall will help secure and protect this Kubota Garden while enhancing the experience of the more than 65,000 people who visit this urban sanctuary each year.

Will the City begin charging admission to get into Kubota Garden?

  • It's crucial that Kubota Garden remains accessible to the public. If at some point in the future the City decides to charge admission, we will work with the community on that transition.

Construction of the perimeter wall was completed in early July 2018. The new wall matches the existing wall extending north of the main entry and closing at the 55th Ave entrance. Additional landscaping was brought up to the walls foundation and new plantings will be planted in front of the wall this spring. In addition to the wall, the exit gate roof was lowered to make it more architecturally proportionate. New stone pavers were also added to this exit. We have been working on fabrication of a maintenance gate and exit gate which will be installed in fall 2019.

Thank you to the Kubota Garden Foundation for fundraising and moving this ornamental wall and gates project forward. Seattle Parks and Recreation and the contractor hired for the project are working to minimize impact to the neighborhood.


Kubota Garden, 9817 55th Ave S, 98178


The Seattle Parks District Major Projects Challenge Fund provides $925,000 in funding for this project as part of the first of 2 phases that also includes a master plan update for the garden and the design/construction of an ornamental wall on the south edge of the parking lot. The Kubota Garden Foundation will match this funding as required by the grant.


Master Plan Update

Completion: February 2019

Perimeter Wall

Planning & Design: Spring 2016 - Winter 2016/17
Construction: Winter 2018/19 - Fall 2019

Project Description

The 2012 Kubota Garden Strategic Plan Update, approved by Seattle Parks and Recreation, identifies the need to complete the enclosure of the garden. This will better secure and protect the garden and help to accommodate the over 65,000 visitors annually to the garden.

The completion of the wall at the northeast corner will provide security to and protection of the Garden by limiting access to the main entry gate. The access from Renton Ave S and 55th Ave S will be closed during construction and will remain closed permanently. Seattle Parks and Recreation and the contractor hired for the project will work to minimize impact to the neighborhood.
