The [https://epg.modot.org/forms/general_files/DE/Location_Study_Report.dotx Location Study] (LS) consists of two parts: the Purpose and Need (P&N) and the Alternatives Analysis. The preliminary P&N is developed early in the study, prior to holding a [[:Category:129 Public Involvement#129.1 Prelocation Study Meetings|prelocation study meeting]] with public and agency input ([http://www.fhwa.dot.gov/hep/section6002/index.htm SAFETEA - LU Section 6002] specifically addresses these requirements). MoDOT and FHWA can modify the P&N over the life of the project. The Alternatives Analysis section is prepared with public and agency input following the prelocation study meeting and is combined with the P&N to form the LS. The district submits the LS to the liaison engineer (with a copy to the environmental section) in Design. All information developed for the LS must consider the environmental constraints identified during scoping prior to the prelocation study meeting as well as all subsequent substantive information developed or received. The district submits the LS to the liaision engineer in the Design Division.

==126.1.1 Preliminary Information Needed==
Upon initiation of a LS, the district submits two copies of a written [[127.1 Request for Environmental Services|request for environmental services]] to the Design Division requesting preliminary screening and early constraint identification for a specified study area. The district will define the study area limits, in coordination with the environmental section of the Design Division, including logical termini, that should be large enough to accommodate the possible range of alternatives which could be considered throughout the study. The necessary study area will be unique to each project and will vary in size based on length of the project, scope of possible improvement, the identified needs and the known physical constraints. The study area is drawn on aerial mosaics and/or USGS quadrangle maps and labeled "Study Area Limits". Two copies of the maps should be submitted with the RES. Environmental and historic preservation specialists will use these maps to research and screen the area for known environmental and cultural constraints. This information will be returned to the district for use in the location study and for use at the [[:Category:129 Public Involvement#129.1 Prelocation Study Meetings|prelocation study meeting]] and the [[:Category:129 Public Involvement#129.2 Agency Scoping Meetings|agency scoping meeting]]. This information is requested at least 2 months prior to the desired date for the prelocation study meeting or the agency scoping meeting, to allow ample time for the screening and constraint identification to be completed.

==126.1.2 Consultant Prepared Location Study==
In the event the district does not believe they have adequate staff to prepare the LS, the district will submit a draft P&N document to the Design Division as part of the documentation used to support the need for additional professional services. If necessary, Design will submit the draft P&N document to the FHWA for review and comment prior to accepting the draft P&N. Once accepted by the Design Division, the documentation to justify the need for additional professional services will be submitted to the Professional Services Committee for their concurrence. After concurrence of the Professional Services Committee, the procedures set out for [[:Category:134 Engineering Professional Services|consultant selection]] and contract implementation will be followed for the solicitation and selection of the consultant. As part of the LS preparation (and throughout the course of the project), the draft P&N may be modified and/or updated as additional information is known.
