No 101033-00 SECTION IX APPENDIX D -TECHNICAL DESIGN SUMMARY The Cities of Bryan and College Station both require storm drainage design to follow these Unified Stormwater Design Guidelines. Paragraph C2 of Section Ill (Administration) requires submittal of a drainage report in support of the drainage plan (stormwater management plan) proposed in connection with land development projects , both site projects and subdivisions . That report may be submitted as a traditional prose report, complete with applicable maps , graphs, tables and drawings , or it may take the form of a "Technical Design Summary". The format and content for such a summary report shall be in substantial conformance with the description in this Appendix to those Guidelines . In either format the report must answer the questions (affirmative or negative) and provide, at minimum , the information prescribed in the 'Techn ical Design Summary" in this Appendix . The Stormwater Management Technical Design Summa ry Report shall include several parts as listed below. The information called for in each part must be provided as applicable. In addition to the requirements for the Executive Summary , this Appendix includes several pages detailing the requirements for a Technical Design Summary Report as forms to be completed . These are provided so that they may be copied and completed or scanned and d igitized . In addition, electronic versions of the report fo r ms may be obtained from the City . Requirements for the means (medium) of subm itta l are the same as for a conventional report as detailed in Section Ill of these Guidelines . Note: Part 1 -Executive Summary must accompany any drainage report required to be provided in connection with any land development project, regardless of the format chosen for said report . Note: Parts 2 through 6 are to be provided via the forms provided in this Appendix. Brief statements should be included in the forms as requ ested, but additional information should be attached as necessary. Part 1 -Executive Summary Report Part 2 -Project Administration Part 3 -Project Characteristics Part 4 -Drainage Concept and Desi gn Parameters Part 5 -Plans and Specifications Part 6 -Conclusions and Attestation STORMWATER MANAGEMENT TECHNICAL DESIGN SUMMARY REPORT Part 1 -Executive Summary Th is is to be a brief prose report that must address each of the seven areas listed below. Ideally it will include one or more paragraphs about each item . 1. Name, address , and contact information of the engineer submitting the report , and of the land owner and developer (or applicant if not the owner or developer). The date of submittal should also be included . 2 . Id entification of the size and general nature of the proposed project, including any proposed project phases . This paragraph sh ould also include reference to appl ications that are in process with either City : plat(s), site plans , zoning requests, STORMWATE R DESIGN GUIDELINES Effective February 2007 Page 1of26 APPENDIX .

DES IGN SUMMARY As Rev ised February 2009 SECTION IX APPENDIX D -TECHNICAL DESIGN SUMMARY or clearing/grading permits, as well as reference to any application numbers or codes assigned by the City to such request. 3. The location of the project should be described This should identify the Named Regulatory Watershed(s) in which it is located , how the entire project area is situated therein , whether the property straddles a watershed or basin divide , the approximate acreage in each basin , and whether its position in the Watershed dictates use of detention design . The approximate proportion of the property in the city limits and within the ET J is to be identified , including whether the property straddles city jurisdictional lines. If any portion of the property is in floodplains as described in Flood Insurance Rate Maps published by FEMA that should be disclosed . 4 . The hydrolog ic characteristics of the property are to be described in broad terms : existing land cover ; how and whe re stormwater drains to and from neighboring properties ; ponds or wetland areas that tend to detain or store stormwater; existing creeks , channels , and swales crossing or serv ing the property ; all existing drainage easements (o r ROW) on the property , or on neighboring properties if they service runoff to or from the property . 5 . The general plan for managing stormwater in the entire project area must be outlined to include the approximate size , and extent of use , of any of the following featu res: storm drains coupled with streets ; detention I retention facilities ; buried conveyance conduit independent of streets ; swales or channels ; bridges or culverts; outfalls to principal watercourses or their tributaries ; and treatment(s) of existing watercourses . Also , any plans for reclaiming land within floodplain areas must be outlined . 6 . Coordination and permitting of stormwater matters must be addressed . This is to include any specialized coordination that has occurred or is planned with other ent it ies (local , state , or federal). This may include agencies such as Brazos County government , the Brazos River Authority , the Texas A&M Univers ity System , the Texas Department of Transportation , the Texas Commission for Environmental Quality , the US Army Corps of Engineers , the US Environmental Protection Agency , et al. Mention must be made of any permits , agreements , or understandings that pertain to the project. 7. Refe rence is to be made to the full drainage report (or the Technical Design Summary Report) which the executive summary represents . The principal elements of the main report (and its length ), including any maps , drawings o r co nstruction documents , should be itemized . A n example statement might be: "One __ -page drainage report dated one set of construction drawings (_sheets) dated , and a ___ -page specification s document dated ____ comprise the drainage report for this project."
