klotz(l)associates Mr. Julian Garza Jr., P.E. July 5, 2011 Page 2 of 7 recommendations and to develop cost for those recommendations. We understand that the City has approximately $900K of construction funds to improve the drainage in the Battleground Estates area. Klotz Associates will develop a Preliminary Engineering Report including supporting hydrologic and hydraulic calculations to submit to the City of La Porte and eventually to Harris County and Harris County Flood Control District (HCFCD) to reflect the alternatives evaluated and proposed improvements to the channels. The goal of this effort is to evaluate and determine what improvements are needed to reduce the structural flooding within the Battleground Estates area. It is planned that this work effort will be a two phase approach with the first phase evaluating the restricted culverts at North P Street and F 101 -00 -00 and the second phase evaluating the local drainage elements within Battleground Estates and the downstream channels. Listed below are the details of the scope. Surveying is anticipated and is included in this scope of work. The results of the surveying will to allow us to extend the hydraulic model further upstream into the Battleground Estates area by picking up channel sizes, flow lines, culvert sizes, location and flow lines and some representative slab elevations. Soils evaluations are anticipated and are included with this scope of services. The soils evaluation will evaluate the soil conditions and to include the results of the soils evaluation into the recommended projects. Environmental investigation are anticipated and are included with this scope of services. The environmental evaluation will evaluate the local area and the results of the environmental investigation will be utilized in the development of the recommended projects. SCOPE OF SERVICES Task #1 - Kick off meeting 1. Kick off meeting with staff to discuss goals /objectives for the plan. Task #2 — Evaluation of restricted culverts at North P Street and F101 and issue letter report 1. Conduct field measurements to get a generalized location, size of culvert and approximate depth of each of the culverts located at the intersection of North P Street and F101-00-00 channel. 2. Have a meeting with Harris County to discuss the overall effort and to understand any improvements or plans that they may have that could impact the drainage in the Battleground Estates area specifically North P Street.
