Fyi, yesterday I spoke the Fire Marshall at length on these standards. The fire code is rather
brief on the subject - 20 ft, all weather, 75K #s... Eric is in agreement with the standards below
and primarily looking for Dev Engr to oversee the permitting of the design and construction to
meet fire code. In short, we should be using the site design stds as a minimum design where the
design engineer is certifying the all weather and 75K... It may be more straightforward for the
engineer to specify the BCS equivalent technical specifications.

Subject: RE: Emerald Ridge Plat
Paul,
Below are some of the pertinent sections. The fire code (excerpts attached) requires a minimum of
20 ft wide access for fire truck, etc. This emergency access easement can be dedicated by plat or
separate easement. The access drive will require PE sealed construction plans, development
permit, designed and tested to ensure the access can support a 75K lb fire truck.
UDO — Art 8.2 E
4.Adequate Street Access.
a.
One (1) external street connection is required for a street serving as roadway access for thirty (30) or
fewer lots.
b.
When there are more than thirty (30) lots to be served by external street connections, a minimum of two
(2) street connections to external paved public streets shall be required. The Commission may allow a
Remote Emergency Access where development phasing or constraints of the land prevent the provision
of a second street connection. Notwithstanding the foregoing, two (2) street connections to external
paved public streets shall be required when one hundred (100) or more lots are served.
c.
Three (3) street connections to external paved public streets may be required by the Commission when
two hundred (200) or more lots are served.
d.
1
Where more than one (1) external street connection is required, at least one (1) external street
connection shall not be located over a potential hazard such as a high - pressure gas line or a creek where
the one hundred -year floodplain overtops the street, regardless of its classification.
Site Design Standards
Pavement and Surfacing
Except as otherwise provided, all off - street parking areas, including drive aisles, driveways and parking
stalls, shall be constructed with a minimum allowable parking lot pavement of one of the following
options:
• Asphalt - a minimum of one and one -half inches (1.5 ") of asphalt pavement on top of six inches (6 ")
of limestone base.
• Concrete - a minimum of five inches (5 ") thick; reinforcement within the concrete section shall consist
of number four ( #4) bars on eighteen inch (18 ") centers, centered within the pavement thickness.
All off - street parking areas shall be installed graded to drain and shall be maintained so as to dispose of
surface water accumulated within the area. Parking spaces shall be arranged and marked so as to provide
for the safe and orderly parking of vehicles.
Non - Public, All- Weather drive surfaces, whether temporary or permanent, that are required for emergency
access or turnaround for emergency vehicles must be constructed to function under all weather
conditions. To accommodate a project during construction, phasing, or permanent installation, drive
surfaces that do not meet the requirements for permanent pavement surfaces may be allowed at the
discretion of the Administrator for the specific conditions stated below:
• Temporary All- Weather Surface (During Construction): A structure under construction must be
accessible by an all- weather drive surface. This surface may consist of the permanent pavement as
described above, or may consist of four inches (4 ") of limestone base with a one - course seal coat as
specified in the Texas Department of Transportation Standard Specifications for Construction of Highways,
Streets and Bridges, 1993 Edition, Item 316. This temporary all- weather surface must be reworked or
replaced to meet the permanent pavement standard as described above prior to issuance of a Certificate
of Occupancy.
• Semi - Permanent All- Weather Surface (During Phasing): In cases during phasing of a large
project, emergency access and turnarounds often must be added as a temporary measure until additional
phases are constructed. These emergency access areas may consist of permanent pavement surface as
described above, or may consist of six inches (6 ") of limestone base with one - course seal coat as specified
in the Texas Department of Transportation Standard Specifications for Construction of Highways, Streets
and Bridges, 1993 Edition, Item 316. If the semi - permanent surface is used, the six -inch (6 ") curb is not
required, and these areas must be gated or protected from public usage and signed for emergency access
only. When the additional phase is constructed these areas must be removed or reworked to meet the
permanent pavement standards as described above.
2
• Permanent All- Weather Surface (Permanent): In some development scenarios, an emergency
access or turnaround must be constructed to meet emergency access purposes and is not required for
public traffic, service vehicles or sanitation vehicles. In these cases, the area required for emergency
access only may consist of permanent pavement surface as specified above, or may consist of six inches
(6 ") of limestone base with a two- course seal coat as specified in the Texas Department of Transportation
Standard Specifications for Construction of Highways, Streets and Bridges, 1993 Edition, Item 316. If the
seal coat surface is used, a six -inch (6 ") curb is not required, and these areas must be gated or protected
from public usage and signed for emergency access only.

Hi Ms Eikenhorst,
Reports are not required for Erosion Control, but there is an Erosion Control Plan for the emergency drive. A drainage
report was not required for the emergency drive since the culvert calculations were previously performed with the
Emerald Ridge development and the Construction Plan shows the road to be following the natural topography. The
permanent road that will be constructed with Phase 2 of Emerald Ridge and will utilize this culvert and follow much of
the same path. Please let me know if you have any further questions.
Sincerely,
Carol L. Cotter, P.E.

Ok, that all makes sense. Any word on the drainage, erosion paperwork? I know 1 sould like a broken record but the
meeting is tomorrow night and I'd like to review the information and have time to digest it! Again, I cannot thank you
enough for all your help. Hope I never have to do this again - Mary

Mary,

Each speaker has three minutes. If there is a large crowd, the Chairman usually requests that if people are going to
speak that they try not to repeat information from a previous speaker. Just a heads up. Each person is welcomed to
bring their own jump drives. I recommend arriving early though so that they can have it placed on the computer. This
saves a lot of time.

Lauren: We are trying to be as organized as possible for tomorrow night. How much time does each speaker have? Do
we need to send all materials to you in advance or can some bring theirs on a jump drive? I have a petition from the
neighbors that I need to scan and fax to you and will get that done latter this morning.
