The proposed sublease for Piedmont Youth Soccer Club is for three years. DISCUSSION Piedmont Youth Soccer Club leased the fields they currently occupy from the ARRA five years ago. During this new lease, Piedmont Youth Soccer Club will upgrade the grass playing field, including grading, installing an irrigation system, and planting fill -in grass, all at their sole expense. Attachment A describes the business terms for the proposed sublease for Piedmont Youth Soccer Club at Fields 424 and 425, located between Buildings 2, 3, and 4. The rent for Piedmont Youth Soccer Club is waived; however, Piedmont Youth Soccer Club shall continue to maintain the field at their sole expense, which is estimated to be approximately $40,000 annually. In addition to maintaining the field, they also pay for the water used, which averages $550 per month. The field will continue to be used for adult and youth soccer. When the field is not in use, it will be available for the Recreation, and Park Director to schedule use. At the end of the Piedmont Youth Soccer Club three -year lease, the soccer field will be managed by the Recreation and Park Department. In accordance with the Exclusive Negotiating Agreement between the ARRA and SunCal Companies, this lease has been discussed with representatives from SunCal Companies and has their concurrence. FINANCIAL IMPACT This lease will generate approximately $6,600 in the first year to pay for water. These funds will be retained by the ARRA.

The proposed sublease for Dreyfuss Capital Partners is for five years, plus five one -year options to extend. DISCUSSION Dreyfuss Capital Partners formerly occupied Building 113 at Alameda Point. In February 2008 the Navy informed the ARRA that they would be conducting screening and testing in four buildings at Alameda Point and that those buildings are required to be empty for these tests. Building 113 was one of those buildings. Attachment A describes the business terms for the proposed sublease for Dreyfuss Capital Partners in a portion of Building 29. Building 29 is in good condition. The rent for Dreyfuss Capital Partners is $29,184 annually, or $0.30 per sq. ft. in the first year. There is a 3% increase each subsequent year. The building will continue to be used for light manufacturing, fabrication, and general office. Additionally, Dreyfuss Capital Partners has asked for a Right of First Offer (ROFO) for the remaining space in Building 29, giving them the ability to meet or exceed any offer the ARRA receives to lease the remaining 8,703 square feet. If Dreyfuss Capital Partners does not respond to the offer presented to them, the ARRA can lease the remaining space. Additionally, Dreyfuss Capital Partners has asked for a ROFO for Building 113, if it becomes available after the Navy has completed their work in the building. Staff recommends approval of a ROFO for Building 29, but does not think Building 113 should be obligated before it is ready for re- leasing. Dreyfuss Capital Partners has also requested a waiver of one month of rent in Building 29 to accommodate their costs to prepare the building for occupancy. Because tenants have been displaced by the Navy's remediation in the past, the ARRA's lease document clearly states the Navy's right to access their property. The tenant had several months Honorable Chair and Members of the October 7, 2009 Alameda Reuse and Redevelopment Authority Page 2 of 2 advance notice; therefore staff does not recommend the waiver of rent. The Navy's clean-up schedule may displace other tenants in the future and staff does not recommend creating a precedence of rent waivers. As much as possible, staff tries to relocate the tenant to comparable space at Alameda Point or provide them with the City's vacancy list to retain the business in Alameda. In accordance with the Exclusive Negotiating Agreement between the ARRA and Sun Cal Companies, this lease has been discussed with representatives from Sun Cal Companies and has their concurrence. FINANCIAL IMPACT This lease will generate $29,184 in the first year. These funds will be retained by the ARRA. RECOMMENDATION Authorize negotiation and execution of a sublease for Dreyfuss Capital Partners in Building 29 at Alameda Point without a waiver in rent and a Right of First Offer for Building 29 only.

The debris from the fire was assumed to contain hazardous materials, and the Bay Area Air Quality Management District (BAAQMD) issued an order to abate the condition. Pursuant to the 1994 Alameda Reuse and Redevelopment Authority (ARRA) Procurement Policy, Section 8, procurement of nonprofessional services can be done by emergency procurement where the Executive Director determined that a public emergency existed and standard procurement was infeasible due to immediate threat of injury to persons or property. This policy allowed the ARRA to sole source any contract necessary to abate the emergency condition. In June, the Interim Executive Director provided the ARRA Governing Board with a written report detailing the circumstances and justification for those emergency expenditures. However, because Catellus had already prepared a demolition plan for the entire site, bids for demolition had already been competitively bid. Staff worked with the low bid contractors, FERMA Corporation and Vista Environmental Consulting, because they provided the ARRA with the quickest, most economical process for compliance with the abatement order. DISCUSSION After FERMA and Vista cleared the debris from around the remaining concrete structures, the next phase of the work plan was to remove asbestos from the structures to allow for demolition and dumping. Upon accessing the concrete structures, it was determined that they were not stable enough for teams to enter and remove the asbestos from pipe lagging, floor tiles and other asbestos mastics. The additional funding needed will allow the contractors to shore up and abate the concrete structures. If the structures are not abated and demolished as-is, the cost for demolition will nearly triple. Staff has tried to reduce the additional costs to the project by requiring bids for scaffolding and any additional subcontract work. In addition, staff recently secured a Honorable Chair and October 7, 2009 Members of the Alameda Reuse and Redevelopment Authority Page 2 of 2 $200,000 grant from the State Department of Toxic Substances Control to assist in the project clean up, so there may be cost savings. FINANCIAL IMPACT The additional $500,000 will come from ARRA lease revenue Fund 858. This is an unbudgeted expenditure and will require a modification to the FY 09-10 budget. RECOMMENDATION Amend the contract and project budget for the fire at the Fleet Industrial Supply Center by adding $500,000. Respectf )Iy submitted, Leslie A.

The procedure delegated to the Executive Director the authority to declare as surplus any item of personal property which is valued at less than $10,000 and which is not required for use by the ARRA in the administration of its powers and duties pursuant to the April 1994 Joint Powers Agreement (JPA). The JPA is between the City of Alameda and the County of Alameda for the purpose of establishing a public entity (the ARRA) for assuring the effective transition of the Alameda Naval Air Station from federal to local ownership. DISCUSSION When the Navy transferred title of certain personal property to the ARRA, it included a Ship Waste Off-Loading Barge (SWOB), which was used in support of the management of the port. This barge is coming close to the end of its service life. Repairs in the approximate amount of $35,000 are required to continue service. NRC Environmental Services is willing to purchase the barge and make the required repairs. Based on previous barge sales, NRC has offered $25,000 for purchase of the barge. Sale of this barge will reduce the ARRA's liability and may result in a reduction of ARRA insurance costs. FINANCIAL IMPACT The offer for purchase will generate $25,000. These funds will be retained by the ARRA. Honorable Chair and October 7, 2009 Members of the Alameda Reuse and Redevelopment Authority Page 2 of 2 RECOMMENDATION Authorize negotiation and execution of a sales agreement, and approve disposing of personal property at Alameda Point — proposed sale of Ship Waste Off-Loading Barge.

Item 4 -A environmental management Alameda Point RAB Meeting on September 3, 2009 Highlights and Analysis RAB members present: Dale Smith (Community Co- chair), Fred Hoffman, George Humphreys, Joan Konrad, Jim Leach, Jean Sweeney, Jim Sweeney, and Michael John Torrey Remediation and other field work in progress: The following activities were noted during the September 15, 2009 BCT meeting: o The Navy is continuing to remove and replace radioactively contaminated stouu drain lines arising at Buildings 5 and 400 and discharging into the Seaplane Lagoon. This work must be completed before cleanup of contaminated sediment in the Seaplane Lagoon begins. o A third debris pile is about to be removed from along the northern bulkhead of the Seaplane Lagoon. At the same time, the Navy will further investigate the large concrete block that is submerged in the area. o Subsurface groundwater treatment is underway at IR Sites 14 and 27, along the Oakland Inner Harbor in the Northwest Territories and just north of Pier 1, respectively. o The air sparge /vapor extraction system to treat groundwater contaminated with benzene and naphthalene at Alameda Point OU -5 and FISCA IR Site 2 is operating. IR Site 1 (1943 -1956 Disposal Area) The Navy presented the draft final Record of Decision (ROD) for IR Site 1. The ARRA Board reviewed a draft comment letter to the Navy at its September 15 meeting. As directed by the ARRA, the comment letter was sent to the Navy on September 17, 2009, signed by both Mayor Johnson and Interim City Manager Gallant. The congressional delegation was copied on the comment letter. RAB Member Hoffman commented extensively about groundwater contamination at one location in IR Site 1. He noted that most of the sampling data from the groundwater plume is very dated, and he expressed the opinion that the plume has not been adequately characterized. The Navy agreed that further characterization is needed to design the cleanup itself, but that the existing characterization is sufficient for the purpose of selecting the clean -up strategy in the ROD. RAB Member Hoffman asked that the BCT consider the adequacy of IR Site 1's groundwater characterization at its next meeting. The BCT discussed this issue at its September 15, 2009 meeting and concluded that existing information about the groundwater plume at IR Site 1 is suitable for selecting a remedy. Environmental regulators reiterated at the BCT meeting that they would require thorough groundwater sampling and analysis (1) to design the clean -up process selected by the ROD and (2) on an on -going basis to detect any contaminant migration that might arise in the future.
