The following table is considered a preliminary list, because it is possible that additional information will be required as the SEPA alternatives are fully defined. Ultimately, all technical reports will need to provide enough detail for adequate SEPA environmental analysis of redevelopment under the Proposed Actions and EIS Alternatives. We recognize that a considerable amount of existing information is available on the project site and project. To the extent that this information is relevant to the Hyla Crossing and Rowley Center EIS, it will be used to prepare, or will be referenced in, the document. In particular, we reviewed the November 2010, SEPA Environmental Checklist and associated technical reports to prepare this memo. As appropriate, information from those documents will be used to prepare the EIS analyses. However, since new alternatives will be included in the EIS, certain information will need to be updated for the EIS. The following table focuses on information that will be needed to describe existing site conditions, and adequately describe and evaluate the EIS Alternatives. It is assumed that the EIS will address two redevelopment alternatives and one No Action Alternative (with two scenarios). Each of the redevelopment alternatives will reflect a range of uses, densities, and infrastructure improvements (i.e. open space and roadways), and will be analyzed at full build- out (assumed to be 2030). This list assumes that, as possible, the Hyla Crossing and Rowley Center portions of the site will be distinguished to effectively portray future development assumptions and allow more efficient impact evaluation of the EIS Alternatives. In addition to information required to describe existing conditions and the alternatives, the end of this table includes space for the information needs of the technical team members for completion of their reports. We assume that each technical team member will contact us with any information needs that go beyond this list. We will update the table, as necessary. The Information Needs table includes a column indicating our assumption about the team member/entity anticipated to be responsible for providing the requested information. Where more than one name is provided in the responsibility column, the first name listed will have the EAIBLUMEN Hyla Crossing and Rowley Center EIS Information Needs Updated April 26, 2011 primary responsibility for coordinating the provision of the information. The table also indicates the date by which the requested information will be needed (or has been provided), and the status of receipt of the information (we will periodically update the status column). Refer to the updated schedule for deliverable dates. Please contact us with any questions on the information needs below.
