team of Balance Hydrologics and LSA Associates, assisted City Staff in securing <br />environmental agency permits for the restoration of the Bernal Property Creeks. Since the <br />start of design work, several changes have taken place which affect the overall design. <br />Sycamore Creek, which intersects Mission Creek, discharges storm water flows to the Zone <br />7 B-2-2 channel on the Bernal Property. Sycamore Creek crosses the Applied Biosystems <br />property and the original creek designs assumed significant modifications to the Sycamore <br />Creek flows based on development of the Applied Biosystems property. Applied <br />Biosytem's expected building phases for future development have not taken place, and <br />subsequently, the anticipated modifications to Sycamore Creek in this area will not be <br />completed, affecting the creek system's overall design. <br /> <br />In addition, since July of 2003, the design plans for the Bernal Property sports field have <br />become more defined with the selection of MD Fotheringham, Landscape Architects, for <br />the design of the sports fields for the 318-acre public land referred to as the Bernal <br />Property. <br /> <br />The design changes to the channels, to be undertaken by LTD Engineering, also include <br />provisions to segment the work to coincide with the Greenbrier Homes Communities, Inc. <br />construction schedule for the Valley Avenue undercrossing improvements under the Union <br />Pacific Railroad. This underpass was a requirement of the residential developments on the <br />Bemal Property. Along with the construction of the undercrossing, the existing channel <br />must be relocated westerly to accommodate the dropping of the road under the railroad <br />tracks. The schedule for the Greenbriar work will necessitate the early construction of the <br />central portion of the creek restoration project, requiring modification of the design plans <br />and the repackaging of the construction documents by LTD Engineering. <br /> <br />Amendment No.1 provides for the redesign of the channels to incorporate changes <br />identified above and provides for the consultant to collaborate and work closely with the <br />firm of MD Fotheringham to create a channel system design that meets both the <br />contributory drainage needs and the n~eds and space requirements for the future sports <br />park. <br /> <br /> SR 05:061 <br /> Page 2 of 3 <br /> <br /> <br />
