SUBJECT:
Traffic Concurrency Test – The Alpine Nursery Preliminary Plat;
File No. LUA15-000018, PP, ECF
The Alpine Nursery Preliminary Plat is a proposed 27 lot subdivision on 9.64 acres. The subject property is roughly rectangular in shape and is a currently a collection of three parcels
on the south side of SE 144th St between 160th and 161st Ave SE. The site is located on Residential-4 dwelling units per acre (R-4) zoning classification. The current use of the parcels
contains two single family residences, a garden nursery, and several detached structures. The site is surrounded by existing single family subdivisions zoned R-4 within the City limits
and Unincorporated King County.
The Traffic Analysis prepared by TraffEx (dated December 31, 2014) included information that the net new peak hour trips generated by the project will be 21 in the weekday AM peak hour
and 28 net new trips in the PM peak hour with a total of 267 net new daily trips. This project passes the City of Renton Traffic Concurrency Test per RMC 4-6-070.D as follows:
Traffic Concurrency Test Criteria
Pass
Implementation of citywide Transportation Plan
Yes
Within allowed growth levels
Yes
Project subject to transportation mitigation or impact fees
Yes
Site specific street improvements to be completed by project
Yes
Traffic Concurrency Test Passes
Evaluation of Test Criteria
Implementation of citywide Transportation Plan: As shown on the attached citywide traffic concurrency summary, the city’s investment in completion of the forecast traffic improvements
are at 130% of the scheduled expenditure through 2014.
Within allowed growth levels: As shown on the attached citywide traffic concurrency summary, the calculated citywide trip capacity for concurrency with the city adopted model for 2014
is 94,476 trips, which provides sufficient capacity to accommodate the 267 additional trips from this project. A resulting 94,209 trips are remaining.
Project subject to transportation mitigation or impact fees: The project will be subject to transportation impact fees at time of building permit for each new single family residence.
The TraffEx report also provided a ‘Traffic Mitigation Requirements’ on page 4 that does not fully comply with the adopted composite of development fees found in Section XI of Resolution
No. 4164 and Ordinance 5670.
Site specific street improvements to be completed by project: The project will be required to complete all internal and frontage street improvements for the plat prior to recording.
Any additional off-site improvements identified through SEPA or land use approval will also be completed prior to final occupancy.
Background Information on Traffic Concurrency Test for Renton
The City of Renton Traffic Concurrency requirements for proposed development projects are covered under Renton Municipal Code (RMC) 4-6-070. The specific concurrency test requirement
is covered in RMC 4-6-070.D, which is listed for reference:
D. CONCURRENCY REVIEW PROCESS:
1. Test Required: A concurrency test shall be conducted by the Department for each nonexempt development activity. The concurrency test shall determine consistency with the adopted Citywide
Level of Service Index and Concurrency Management System established in the Transportation Element of the Renton Comprehensive Plan, according to rules and procedures established by
the Department. The Department shall issue an initial concurrency test result describing the outcome of the concurrency test.
2. Written Finding Required: Prior to approval of any nonexempt development activity permit application, a written finding of concurrency shall be made by the City as part of the development
permit approval. The finding of concurrency shall be made by the decision maker with the authority to approve the accompanying development permits required for a development activity.
A written finding of concurrency shall apply only to the specific land uses, densities, intensities, and development project described in the application and development permit.
3. Failure of Test: If no reconsideration is requested, or if upon reconsideration a project fails the concurrency test, the project application shall be denied by the decision maker
with the authority to approve the accompanying development activity permit application.
The Concurrency Management System established in the Transportation Element on page XI-65 of the Comprehensive Plan states the following:
Based upon the test of the citywide Transportation Plan, consideration of growth levels included in the LOS-tested Transportation Plan, payment of a Transportation Mitigation Fee, and
an application of site specific mitigation, development will have met City of Renton concurrency requirements.
