The fire flow requirement for a single-family home is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. The proposed fire hydrant plan looks acceptable. 2. Fire department apparatus access roadways are required to be a minimum of 20-feet wide fully paved, with 25-feet inside and 45-feet outside turning radius. Fire access roadways shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required within 150-feet of all points on the buildings. Dead end streets that exceed 150-feet in length require an approved turnaround. Renton Regional Fire Authority has approved the variance request to provide approved fire sprinklers in all new homes and waived the fire apparatus turnaround requirement. The dead-end street shall have “No Parking – Any Time” signage on the north side of the street only to provide adequate access width. 3. The fire impact fees are currently applicable at the rate of $829.77 per single family unit. This fee is paid at building permit issuance. Credit will be granted for any existing homes that are removed or retained. Technical Services: (Contact: Amanda Askren, 425-430-7369, aaskren@rentonwa.gov) 1. After reviewing the preliminary plat and understanding the end goal with the properties on the eastern boundary line, a Boundary Line Adjustment seems more appropriate [than encroachment tracts] to move the boundary lines for all properties. The Tracts could be transferred as proposed, but the property owners to the east would then have 2 parcel numbers for their lots – 1 the original and the other the new tract, which may cause future issues for the property owners. 2. The Boundary Line Adjustment would be processed and recorded prior to short plat recording. This would eliminate any concern or additional language needed on the short plat regarding the tracts, ownership, and maintenance. All property owners would need to sign on the face of the Boundary Line Adjustment and the transfer documents that would be recorded separately by the applicant after the BLA is recorded. This would allow the properties to maintain their existing parcel numbers and add the land with the transfer documents. With this being completed prior to the short plat, a new title report will be necessary for final short plat review to confirm the legal description and exceptions. Community Services: (Contact: Leslie Betlach, 425-430-6619, lbetlach@rentonwa.gov) 1. Parks Impact fee per Ordinance 5670 applies. Police: (Contact: Cyndie Parks, 425-430-7521, cparks@rentonwa.gov) 1. None. Building: (Contact: Craig Burnell, 425-430-7290, cburnell@rentonwa.gov) 1.
