Traditional
Neighborhood
Developments
(TNDs)
What they are
and how they will
affect CSFD
1
What is a TND?
• A new zone within the City of Colorado Springs.
• Based on a pedestrian environment that is more
people-oriented than auto-oriented.
• East meets West (narrow streets seen in the
Northeast United States, come to Colorado)
• TNDs encourage a pattern of neighborhood
development that was commonly built prior to
World War II. (Old Colorado City and central
Springs)
2
How will TNDs affect CSFD?
Narrow Streets
In order to facilitate a more pedestrian oriented
zone, the most significant aspect affecting CSFD
is narrow streets.
Density of Structures/Residents
Narrow streets coupled with tightly spaced
structures and high numbers of residents create a
unique challenge for emergency responders.
3
Why were TNDs allowed?
The narrow street dimensions permitted within a
TND are a far cry from what everyone has been
accustom to throughout the majority of the City.
With that being said, certain built-in design features,
based on apparatus criteria, were incorporated into
the TND ordinance which will allow emergency
responders adequate access.

Design Features Continued
15ft Obstruction Triangle
No above ground obstructions such as fire
hydrants, streetlights, trees or traffic signs are
permitted within 15’ of an intersection of
roadways 28’ in width or less.
This, along with reinforced curbs and no parking
zones are designed to allow apparatus to utilize
curbs for their turning needs if the roadway is
otherwise restricted.
8
Design Features Continued
No Parking Zones
At all intersecting
streets of 28’ or less,
30’ no parking zones
are designed to ensure
adequate apparatus
turning radii.
9
Design Features Continued
No Parking Zones Continued...
No parking is permitted within 20’ of the
intersection of an alley and a TND roadway. This
is regardless of the width of the roadway
intersecting with the alley.
The no parking zones are to be designated as “Fire
Lanes” regardless if the roadway is private or
public.
10
Design Features Continued
Queing Areas (No Parking Zones)
These are provided midblock (of blocks greater
than 300’ in length) of streets 28’ or less in width
for firefighting purposes. These areas are
designated as “Fire Lanes.” (Striped or posted)
They are designed to allow an area for aerial
apparatus operations, since the narrow streets may
not facilitate adequate clearance for the fully
extended outriggers. (see slides #24, #25, #26)

Tactical Considerations
(Not in any special order)
• Utilize entire roadway. Turning radii should be adequate
when using the entire roadway and not just the “proper”
lane.
• Anticipate arrival sequence. Most likely there will be
times where driving past the structure (seeing 3 sides) and
keeping the front open for the truck, prohibits the truck
from maneuvering around the engine if they are coming
from the opposite direction.
• Address exposures. Due to the close proximity of adjacent
structures, units arriving with heavy fire showing from the
B and/or D sides will be presented with immediate
exposure concerns.
32
Tactical Considerations
• Utilize queing areas. Queing areas are designed for aerial
operations. Granted, the structure on fire may be a few
structures from the queing area, but with those blocks that
have continuous attached housing, the queing area
becomes an important operational aspect.
• Anticipate equipment needed. Most likely, the last
arriving units for a working fire or any units arriving
thereafter (additional alarms), will not be able to position
close to the fire building unless planned. Therefore, late
arriving units should carry as much equipment from their
apparatus as potentially needed. Additional alarms for
labor may be necessary.
33
Tactical Considerations
• Anticipate water demands. Considerations for adequate
water supplies should be made early in an incident. It may
be good practice to utilizing double lays regardless of size
of fire, for every confirmed working fire.
• Hydrant location familiarization. For streets 28’ in width
or less, the hydrants will not be located on the corners of
streets. Most likely they will be located 20’+ from the
corners. This may play a role in establishing water
supplies.
• Increased ground ladder usage. Truck companies may
not be positioned to be optimally utilized. Ground ladders
will be needed to supplement the lack of aerial devices.
34
Tactical Considerations
• Take advantage of fire protection systems. Under certain
circumstances, fire protection systems (namely fire
sprinkler systems and standpipes) may be required to
potentially offset a given hazard or condition. In order for
these systems to function properly, always remember to
supply the FDC.
• Increased use of preplans. Since the TND concept is new
to CSFD, it will benefit company officers to become
familiar with the street layout, building arrangement,
construction type, hydrant locations, fire protection
systems, FDC locations, special hazards/considerations,
etc.
35
Tactical Considerations
• Building addressing. Currently, there is no special
addressing scheme for those homes that also have a
granny/in-law apartment above the garage. Enumerations
will assign those apartments above the garages a regular
address. This means that 417 Sycamore Grove (as an
example) may be for the main building or the accessory
building (in-law apartment). All buildings should be
addressed from both the main street and alley if applicable.
36
Inspection Considerations
(Not in any special order)
• Hold contractors/developers accountable. Since access
is imperative for the success of TNDs, hold the
contractors/developers accountable for building to the
approved plans.
• Start inspections early. Again, since access is imperative,
inspections early on will ensure that adequate access is
maintained throughout the construction process.
• Establish fire lanes and hydrants. Section 8704 of the
UFC requires that fire lanes and hydrants be in place prior
to construction. Due to the inherent tight access, in-place
approved fire lanes and hydrants are essential.
37
Inspection Considerations
• Hydrant Marking. The TND ordinance allows CSFD the
flexibility to require additional features. One of these
features may be to require roadways along hydrants to be
marked to 1) assist apparatus in locating hydrants and 2)
help prevent vehicles parking in front of hydrants.
• Require documentation. This is particularly critical for
the reinforced concrete curbs in which our apparatus may
use to make turns. The only way to ensure that these are
designed as specified is to require signed documentation
that states they are installed as specified.
38
Inspection Considerations
• Seek approved plans. The approved set of development
plans will have all locations of fire lanes and will define
each street width as well as any other specialized design
feature.
• Review the TND ordinance. You will receive two copies
of the TND ordinance (one for the office and the other for
your vehicles).
• Be familiar with Tactical Considerations. Chances are
you will be asked questions from Operations. Knowing the
tactical considerations and where the thought process came
from in regards to TNDs will assist you in answering those
questions.
39
Inspection Considerations
• Building addressing. Currently, there is no special
addressing scheme for those homes that also have a
granny/in-law apartment above the garage. Enumerations
will assign those apartments above the garages a regular
address. This means that 417 Sycamore Grove (as an
example) may be for the main building or the accessory
building (in-law apartment). All buildings should be
addressed from both the main street and alley if applicable.
40
Engineering Considerations
• Placement of hydrants. Since certain street intersections
rely on obstruction triangles for access, be sure to remove
any proposed fire hydrants from these locations.
• Hydrant Marking. The TND ordinance allows CSFD the
flexibility to require additional features. One of these
features may be to require roadways along hydrants to be
marked to 1) assist apparatus in locating hydrants and 2)
help prevent vehicles parking in front of hydrants.
41
Engineering Considerations
• Building addressing. Currently, there is no special
addressing scheme for those homes that also have a
granny/in-law apartment above the garage. Enumerations
will assign those apartments above the garages a regular
address. This means that 417 Sycamore Grove (as an
example) may be for the main building or the accessory
building (in-law apartment). All buildings should be
addressed from both the main street and alley if applicable.
• Additional Fire Protection Features. There may be
instances where the “built-in” features do not adequate
address the hazard. The ordinance allows flexibility to
require additional fire protection features.

Proposed TND Locations
• Gold Hill Mesa (Stations 3, 5 & 13). This TND
has passed the concept plan stage. But before
construction is permitted to begin, it must pass a
development plan stage. No word as to when the
development plan will be submitted. The area
Gold Hill TND proposes to incorporate includes
the vacant lands east of 21st, south of Highway
24, north of Gold Camp and west of 8th.

Feedback NEEDED!
• The TND ordinance is scheduled to be revisited
within 2 years of adoption. This means that it will
be revisited within the next year! It is imperative
that legitimate feedback is received, either good,
bad or ugly regarding the TNDs. Comments as to
what isn’t working, and even suggestions to
improve the TNDs is sought.
