S T R E E T. D R I V E W A Y A N D P R O P E R T Y T R A N S I T I O N S For street improvement and widening projects, transitions to existing improvements are typically the most challenging component of design. Street transitions will require that improvements be constructed at ultimate locations with interim design being implemented. Therefore, the improvements must be constructed so that no reconstruction of permanent improvements will be required and interim transitions are safe and functional. Many of the adjacent properties have significant vertical elevation differences and will require significant grading to accommodate proper transitions to the proposed improvements. Using the topographic mapping, TKE will review vertical alignment designs that will analyze environmental impacts, impacts to adjacent properties and developments, impacts to adjacent streets, conveyance of offsite drainage, street drainage, earthwork, utility relocations, slope and temporary construction easements, traffic impacts, constructability reviews along the proposed street alignments. The analysis will include a report identifying potential impacts, mitigation requirements and quantities as appropriate for each item listed above and will include preliminary profiling for each alternative. D R A I N A G E Design of drainage conveyance must be developed early during design to identify locations of structures. In particular, catch basins or dry xxxxx must be identified to eliminate potential conflicts. In addition, hydrology and hydraulic calculations must be performed early to adequately size the required drainage structures in accordance with the City’s master plan. U T I L I T Y C O O R D I N A T I O N Based on field review, various utilities will require relocation. These facilities include power poles, risers and utility vaults. We will identify these facilities early in project design to begin coordination at the earliest opportunity. TKE has extensive experience coordinating with SCE for the relocation and undergrounding of existing power poles. Agencies that maintain private utilities can be cumbersome and early coordination will prevent project delays. P A V E M E N T R E H A B I L I T A T I O N Review of the pavement conditions on XxXxxx Boulevard indicate that pavement conditions vary from fair to complete structural failure. TKE will review the pavement conditions and offer alternatives which have varying life expectancies, upon the City’s request. Included with the Geotechnical...
