TRANSPORTATION IMPACT FEES The transportation impact fees for the Camellia Court development are based on the current impact fees and could increase when the fees are actually paid. The current traffic impact fees for 2023-2024 are $7,550.02 per dwelling unit for the apartment uses. A credit for the existing single-family home is $12,208.54 per unit and $29.88 per square foot of strip retail plaza. The total credit for the existing structures is $174,820.62 for the single-family housing and retail plaza. The Camellia Court is proposing to include 74 apartment units, resulting in a transportation impact fee of $383,880.86 after credit has been accounted for. Camellia Court March 2023 Traffic Analysis Page 4 090223009 4. CONCLUSIONS The Camellia Court development is proposed to include a 74-unit multifamily residential building. The site is currently occupied with three residential units and 4,625 SF of shopping center. The development is anticipated to generate 252 new ADTs with 18 new AM peak-hour trips and 8 new PM peak-hour trips. The peak-hour trip generation falls below the City of Renton threshold of 20 peak-hour trips for requiring a full traffic impact analysis. The current transportation impact mitigation fees totals $383,880.86 with credit for the existing uses; however, the actual fee will be determined when a complete building permit application is filed.
