Floyd Snider Inc 3/8/2019 Amendment 8

/1.44/%/--Ae PUBLIC WORKS *44 MEMORANDUM TO: Ryan Sass,Public Works Director FROM: Mark Sadler,Operations Superintenden " ��:��'� DATE: February 4, 2019 RE: Amendment 8 to the Floyd and Snider PSA for the Everett Riverfront Amendment No. 8 to the PSA with Floyd and Snider is for an additional budget of$244,000.00 to aid the city in completing the review of the Phase I Shelter Holdings plans at the Everett Riverfront. Shelter Holdings Phase I plans are to complete about 3000 LF of a new main road between 41'and 36th(which will be dedicated to the city) and to construct 4 multi-family and multi-use buildings with(rough) approximately of 75,000 SF with a 30,000 SF grocer and 60,000 SF cinema. The multi-family residential buildings have the first floor as commercial leased properties with five floors of residential above. The Main Road is scheduled to start construction in early May of 2019; and the pile foundation work to start August of 2019 for the Phase I buildings. Occupancy is scheduled in August of 2021. Shelter Holdings six phase plan will take several years and cost several hundred million to complete. All six phases will be constructed over the former Everett Landfill and Tire Fire Site, and must comply with the Consent Decree requirements and be protective of the environment. The city holds the liability for the environmental protection and to ensure compliance with all CD provisions. Phase 1 will be the initial construction for occupancy on the Riverfront to implement all provisions of the CD. Many of the design elements will be the first time the city has had to review and oversee—such as landfill gas collection under buildings that will be occupied;gas monitoring systems;piles being constructed through an aquitard; and buildings and fixed structures that can be impacted due to landfill settlement. The amendment with Floyd and Snider addresses the unique design elements of the site and the required construction oversite and demonstration of compliance of the CD,with the needs of the Building Official and Fire Marshall offices for their specialty reviews. For example the amendment includes: • A geotechnical engineer subconsultant familiar with the landfill to address pile foundations that will penetrate the aquitard. These piles must protect the contaminated leachate from penetrating and impacting the groundwater below,but must also meet the foundation and structural design needs. • The same geotechnical engineer subconsultant to address settlement due to the landfill on buildings, utilities,utility connections, and building connections. • A landfill gas consultant that will assist in the review of the developer's landfill gas collection system design,the landfill gas protection and monitoring measures for buildings, and for the electrical and power service to the facility to be designed and constructed safely within a landfill. The amendment provides for Floyd and Snider to continue to assist staff in plan review of all the specialty review needs, and the construction oversight including the quality assurance and quality control plans for design and construction are completed to meet the CD requirements.
