SUBJECT: Additional Changes to Wetland/Stream Mitigation Plan
Liberty Gardens Plat, File No. LUA08-093
To Whom It May Concern:
Thank you for submitting the wetland/stream mitigation plan and monitoring proposal for the
Liberty Gardens Plat. We have reviewed plan dated February 24, 2014 prepared by your
wetlands consultant Wetland Resources. This letter is sent to advise you of the changes needed
to obtain approval of your final wetland mitigation plan.
Changes needed to Wetland Mitigation/Monitoring Plan:
1. Written specifications and descriptions of compensation techniques shall be provided
im:luding: a planting plan specifying plant species, quantities, locations, size, spacing,
and density; source of plant materials, propagates, or seeds; water and nutrient
requirements for planting; where appropriate, measures to protect plants from
predation; specification of substrata stockpiling techniques and planting instructions
2. Plan sheets need to identify the size, category and class of each wetland and a clear
legend. The legend should include the signs, fence. utility lines, etc.
3. Finally, the mitigation plan is required to be revised to provide adequate buffer for
Wetland C. The required buffer will likely create a "paper" fill of the wetland which will
be required to be mitigated in accordance with King County Code. Please revise the
mitigation plan accordingly.
Monitoring and Maintenance Period Start Date: Once the mitigation project has been
installed, please provide me with the wetland consultant's written confirmation of installation
pursuant to the final approved mitigation plan. The date the City receives this written
confirmation will constitute the beginning of the minimum 5-year maintenance and monitoring
period.
As Built Plans for the Mitigation Area: A copy of the as-built plans of the approved mitigation
plan, prior to recording; unless an installation surety device is provided or if plantings are
installed as exactly per plan.
Monitoring and Maintenance Surety Amount: In order to provide you with the amount of
security necessary for the maintenance and monitoring of the wetland mitigation plantings,
signage, and fencing, we will need a copy of the signed maintenance and monitoring contract
for this work. A draft (followed by a final) maintenance and monitoring contract (or contracts)
for our review prior to execution of the contract shall be provided. The draft contract language
Renton City Hall • 1055 South Grady Way • Renton, Washington 98057 • rentonwa.gov
must ensure compliance with both the performance standards of the Sewall Wetland
Consulting, Inc., mitigation plan as well the maintenance and monitoring standards of the
Renton Municipal Code. The scope of the contract must clearly cover the cost of plant
maintenance and replacement as well. The language in the contract must also guarantee that
"structures, improvements. and mitigation perform satisfactorily for a period of 5 years" (e.g.
add provisions for plant replacement and weed removal referencing compliance with the
survival rates noted in the final approved wetland mitigation plan. The contract must include
quarterly monitoring reports for the first year and annual reports thereafter. The draft contract
must be followed up with a final signed contract once the City approves the draft version. Once
the City approves the contract proposal, the applicant will need to provide a maintenance surety
device (a letter af credit or irrevocable set aside letter) set at an amount totaling 125% of the
cost to guarantee satisfactory performance for a minimum of five years.
Wetland Information Needed on Final Plat Map: All critical areas and their buffers be placed in
either a Native Growth Protection Tract or Native Growth Protecti.on Easement.
Feel free to contact me at 425-430-7219 with any questions.
