TASK 4 - DESIGN OF SOUTH ALIGNMENT SHIFT OF SANDY LAKE ROAD at / MacARTHUR BOULEVARD SCOPE OF WORK The purpose of this task element is to determine both the design and construction cost impacts of a southward shift of the centertine alignment. This shift is contemplated to attempt to mitigate the impacts to property owners due to right-of-way acquisition along the north side. Sverdrup recommends that some preliminary alignments be developed along with the associated roadway cross sections to evaluate cost trade-offs of an alignment shift. Sverdrup would also analyze roadway functionality due to a shift in alignment. ~'I I I ]11' I 07/18/95 08:30 ~214 521 3539 SVERDRUP DALLAS 005 APPENDIX "A" The effort associated with this task should be only to develop a reasonable cost estimate of construction costs to provide an alignment shift. Our concern is that encroachment into the existing 80' wide drainage easement may require construction of Iow retaining walls to maintain the required flow area. Aisc, encroachment into the drainage easement, or placement of any fill material, may require a hydrologic/hydraulic analysis to determine adequacy of the channel configuration. Sverdrup proposes that a brief Summary Report be prepared to address the feasibility and costs associated with an alignment shift rather than propose a design fee to accomplish the alignment shift. Sverdrup proposes the following to provide City of Coppell with the feasibility of an alignment shift: (a) Prepare preliminary alignment drawings using our current CADD database (b) evaluate impacts to the 80" Drainage Easement along south PJW. (c) develop rough '~vorking" drawings of Mac. Arthur Blvd./Sandy Lake Road intersection. (d) determine traffic impacts due to intersection offset & modifications needed to maintain turn lane storage oh MacArthur, median island configuration, radius returns, crosswalk changes. (e) evaluate impacts to existing drainage structures along 80' Drainage Easement. DELIVERABLES (a) Preliminary alignment drawings (b) "Working" Drawings of Mac, Arthur Blvd./Sandy Lake Road intersection depicting revisions required to existing features (median, tum lanes, etc.) (c) Cross-Sections of revised alignment (d) Summary Report addressing impacts including a construction cost estimate and design fee estimate to accomplish the shift. 5. TASK 5 .-.{OPTIONAL) SCOPE OF WORK (a) Sverdrup Corporation is currently preparing the Sandy Lake Road project for Dallas County Department of Public Works utilizing Intergraph Micro-Station.
