::� CobbFendley <br />September 25, 2009 <br />Mr. Steve Gillett AUTHORIZATION FOR <br />Director of Public Works PROFESSIONAL SERVICES <br />City of La Porte <br />604 W. Fairmont Pkwy. <br />La Porte, Texas 77571 <br />Re: McCabe Road Sanitary Sewer, La Porte, Texas <br />Sanitary Sewer and Sidewalk Installation <br />Proposal for Professional Engineering and Surveying Services <br />Dear Mr. Gillett: <br />We are pleased to propose professional engineering services to you in connection with the <br />design and construction of a sanitary sewer and sidewalk along the north side of McCabe <br />Road. The sewer would run from Taylor Bayou (HCFCD #A104-00-00) east to a point opposite <br />a tract boundary line on the south side of the road, and about 200 feet west of an unnamed <br />tributary (HCFCD #A104-12-01) near Old Highway 146. The sidewalk would be somewhat <br />longer, running from the new elementary school on the west side of Taylor bayou all the way to <br />Old Highway 146. It is anticipated that the sidewalk will be placed (wholly or partially) in an <br />easement adjacent to the right of way. Due to existing utilities located near the right of way <br />line, the sewer is proposed to be located of the front slope of the roadside ditch, or in the <br />adjacent easement where available. <br />SCOPE OF SERVICES <br />The specific tasks to be performed by CobbFendley in conjunction with this project are as <br />follows: <br />Basic Services <br />Surveying <br />K <br />3 <br />4 <br />Perform a Category 6, Condition II topographical survey in accordance with the <br />requirements of the Texas Society of Professional Surveyors to locate existing utilities, <br />appurtenances and pavement and to determine the existing elevations of the street and <br />utility lines which are accessible by manholes and the existing ground elevations within the <br />area from the northern edge of pavement to the apparent north right of way line. The <br />adjacent wooded land for the possible location of an easement is assumed to be relatively <br />flat and only obvious topographic features will be obtained there. Proof of right of way will <br />not be researched; only apparent right of way occupation will be used. As an option, the <br />survey can be extended to include a strip15 ft wide inside the existing mobile home park if <br />an easement is to be pursued in that location. <br />Perform utility record research. Utilities will be placed in the drawing based on utility record <br />interpretation as SUE Levels C and D as described in ASCE manual of practice. <br />All benchmark information will reference NAVD '88. <br />Plot all survey data on plan and profile style sheets at a scale of 1" = 20' horizontally and 1" <br />= 2' vertically. <br />D:\DOCS\PROPOSALS\SMALL PROPOSALS\20091A PORTE MCCABE SEWER\PROPOSAL.DOC <br />13430 Northwest Freeway, Suite 1100 1 Houston, Texas 77040 1 713.462.3242 1 fax 713.462.3262 I www.cobfen.com <br />
