DP fee is 1 % of the public infrastructure construction costs or $600 , whichever is greater. In this case it should
be $600 since the storm drain lines are private. Alan, please confirm.

Jeff,
This looks fine. I haven't pulled the file,
but believe we need several items/hard
copies, such as: a development permit, fee,
4 sets of construction plans, and 1 drainage
report -so I can stamp the plans and report
-this will return 1 set to the contractor.
Provide additional sets if you want more than
one set. Please let the contractor know that
they will need to bring a copy of the NOI
when they come in to sign the permit. If you
need stamped sets before a contractor is
engaged, we can release additional sets
stamped "not for construction".

Jeff,
Talked to Erika and Teresa, this work could be permitted with a standalone DP independent from
future Falcon Point development. I should elaborate that the App D should be accompanied by an
analysis addendum to confirm that 100 yr flow is contained the pipe or has a path without flooding
the existing and proposed buildings.
Let us know if you have questions.

No. I got a call from Scott Ball and he had some information that this line was not going to be allowed to be

If not, I'll send you the updated App D.

Not sure if you remember, but we have been working with Scott Ball on the
Falcon Point Condos to acquire a drainage easement from the Huntington
Apartment property owners in order to drain the area behind his current and future
buildings without relocating existing electrical facilities.We recently received a
copy of the filed easement (see attached).
Scott would like to build the storm drain as shown on the attached drawing.
Please let me know what steps are needed to to construct this private drainage

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.

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,

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."

RE : Falcon Point Condo and Huntington Apartment dra inage improvements
MBESI No .: 1000-0243
Dear Alan ,
An agreement between the owner of the Falcon Point Condos and the owner of the Huntington
Apartments have reached an agreement to collect and divert the water from the Huntington
Apartment complex along the ir shared property line . As part of that agreement, we have
designed a drainage system to handle the 100 year flood from the Huntington Apartment
complex. If that system is installed per plans, no water will enter the buildings on either the
Huntington Apartment property of the Falcon Point Condo property. Please let me know if you
have any questions .
Thanks
