Dear Ms. Karoly:
The purpose of this letter is to respond to your February 16, 2006 letter requesting further information.
The original questions/requests are copied below as they appear on the 2/16/06 letter and are then
followed by our response to each.
Additional Information Requested
1. The DWQ still maintains that the road crossing labeled as "Road D-Crossing #3" on the
plans does not appear to be necessaryfor development of the site as currently proposed.
Please eliminate the road crossing and submit revised plans for this area. Additionally, in
your correspondence to the DWQ dated February 14; 2006, you indicated, "this crossing is
needed for internal connectivity, to insure safety due. to the number of lots served and to
accommodate future development to the northern portion of the property. " Based on the
submitted plans, the DWQ believed this impact and the impact labeled `Future Impact" to
be unnecessary. The DWQ also has concerns with cumulative impacts associated with the.
"Future Development ", and avoidance and minimization issues with the citing of lots
adjacent to the pond located within the "Future Development" area.
As per our meeting discussion on March 1, 2006, I am providing a copy of the memorandum from
Zebulon's Planning Department regarding their Special Use Permit requirements and Fire Code
Guidelines. These two documents were provided to justify Road D-Crossing #3.- These two documents
were also presented to justify the "Future Impacts" and "Future Development".
In addition to the justification provided for Road D-Crossing #3, MacGregor Development Company also
proposes to restorelenhance this riparian buffer along the stream channel associated with this crossing.
The Guidelines for Riparian Buffer Restoration 'Division of Water Quality-January 2001 document will
be followed for this riparian buffer restoration. Basically, planting two native species.trees at a density
sufficient to provide 320 trees per acre at maturity and at anapproximate 10x10 feet spacing.
In regards to the avoidance and minimization issues with citing lots adjacent to the pond, it is a
requirement of Zebulon's Special Use Permit that lots are not to be platted within the Neuse 50' Riparian
Buffer. _

FIRE DEPARTMENT ACCESS
Based on the 2000 edition of the International Fire Code
The Fire Department is required to respond to a multitude of emergencies in various types of
buildings and occupancies. These include single-family dwellings, apartment buildings,
shopping malls, business complexes, industrial complexes, hospitals, and nursing homes. To
provide effective fire fighting operations, we must be able to reach all structures by way of
approved access roadways, streets, or driveways.
To assist developers and designers in meeting our requirements, we have defined some terms and
listed minimum design standards considered necessary for effective fire fighting operations.
u Fire Department Access
An approved route that is always available for use by fire trucks and is designed to meet fire
equipment load requirements. Except for Loop Lanes, Shared Driveways, and Private
Driveways, all access routes must be at least 20' wide. When a dead-end access route
exceeds 150' in length, an approved turn around area must be provided.
a Public Street Access
A Fire Department Access route on a public right of way. Public street access routes must
comply with the City or County road design standards and also must comply with the
International Fire Code.
u Private Street Access
A Fire Department Access route on private land. Private street access routes must comply
with the International Fire Code.
u Grades
Street grades shall comply with City or County design standards for both Public and Private
Street Access routes. Maximum grade shall not exceed 8% (12% allowed in hilly terrain).
a Grades on Turn Around Areas
Maximum grades on turn around areas shall not exceed 4%.
Residential Cul-De-Sac Residential Looped Lane
u height
All Fire Department access routes shall have at least 13 feet, 6 inches of vertical clearance
for the entire required width.
u Looped Lane
A Fire Department Access route in a public right of way, consisting of a looped road that
must be at least 16' wide. Looped lanes may be approved for residential subdivisions and
must be designed to approved standards (see design pages).
a Private Driveway
A private driveway designed for the use of occupants of no more than two single-family
dwelling units or one two-family dwelling unit. If the dwelling units are located more than
100' from an approved Fire Department Access route, the private driveway must meet our
minimum design standards: At least 12' wide; grades not to exceed 12%; adequate turn
arounds provided if over 150' long; width to be increased if sharp curves are included;
constructed with an all-weather surface and able to support the weight of a fire truck.
u Shared Driveway
A Fire Department Access route on private property, serving three or more single-family
units. A shared driveway must be at least 16' wide and be designed to approved standards
(see design pages).
u Residential Cul-De-Sac, Commercial/Industrial Cul-De-Sac
An approved turnaround area for public right of ways or private property, designed to Fire
Department standards (see design pages).
E3 Tee Turnaround, Alternative Turnarounds
An approved turnaround area for private property designed to Fire Department standards (see
design pages).
............................................................................
ACCESS GUIDELINES
The following guidelines represent this department's efforts to maintain consistency
concerning Fire Department emergency access. It is our responsibility to ensure adequate
access for Fire Department emergency responders. We therefore reserve the right to require
modifications to established requirements if, in our opinion, the access cannot be provided or
may be compromised.
Tyne of Surface
All access roadways shall be finished by application of an all-weather driving surface
of hot mix asphaltic concrete or concrete pavement over a flexible base capable of supporting
a design wheel load of 18,000 pounds (GVW 80,000 pounds minimum; H-20 loading).
The roadway design must be prepared and certified by an engineer registered by the
State of Colorado. Any required Fire Department access within 100 feet of any building
must meet the same wheel-loading criteria.
All required access roadways must be properly maintained and kept clear for
emergency use at all times.
Any alternatives to these specifications must be reviewed and approved by the Grand
Junction Fire Department prior to construction.
Two Points of Access
Providing two points of fire apparatus access has the following benefits:
? If one access route is blocked, emergency responders have a second route to the property.
? If an emergency requires evacuation of an area, the public will have an alternative exit
route should one route be blocked by the emergency incident.
When two points of access are required, they shall be placed a distance apart equal to not
less than one half of the length of the maximum overall diagonal dimension of the property
or area to be served, measured in a straight line between accesses. The Grand Junction
Fire Department does not allow the second access point limited to use by emergency
responders only. The second access must always be available for public use in case the
other access is blocked.
Commercial and Industrial Developments:
? Buildings or facilities exceeding 30 feet or 3 stories in height shall have at least 2 means
of fire apparatus access.
? Buildings or facilities having a gross building area of more than 62,000 square feet shall
have at least 2 means of fire apparatus access. If the buildings or facilities are provided
with an approved automatic fire sprinkler system, the gross building area can be
increased to 124,000 square feet with one access road.
Multi-family Residential Developments:
? Multi-family residential projects having more than 100 dwelling units shall be provided
with at least 2 means of fire apparatus access.
? Multi-family residential projects of up to 200 dwelling units, which are provided with an
approved fire sprinkler system, may have one means of fire apparatus access.
One or Two Family Residential Developments:
? Developments where the number of dwelling units exceeds 30, shall be provided with
separate and approved fire apparatus access roads.
? Developments where the number of dwelling units is 60 or less may be served by a single
fire apparatus access road, provided all dwelling units are provided with approved
residential fire sprinkler systems.
Aerial Apparatus Roadway Width
? Fire apparatus access roadways shall have a minimum unobstructed width of 26 feet in
the immediate vicinity of any building of portion of building more than 30 feet in height.
At least one of the required access routes meeting this condition shall be located within a
minimum of 15 feet and a maximum of 30 feet from the building, and shall be positioned
parallel to one entire side of the building.
Maintenance of Access Roads
Maintenance of the required access shall be considered during the planning stages and
installation of Fire Department access roadways, fire hydrants, or connections. This includes
the potential growth of trees and/or other vegetation over the years.
Divided Entryway
A divided entryway can present a challenge to emergency vehicles. The required width of
the driveable surface in a divided entryway is based on the width of the entryway and that of
the street fronting it.
? If the street fronting the divided entryway is 28 feet wide, each lane of the entryway must
be at least 15 feet wide.
? If the street fronting the divided entryway is 34 feet wide, the entryway lanes may be less
than 15 feet wide, but cannot be less than 12 feet wide.
? For fronting streets wider than 34 feet, entryway lanes must be at least 12 feet wide.
No Parking SignaEe
For access routes less than 28 feet wide and for fire apparatus turnaround areas, vehicle
parking is not allowed. No Parking signs, are required. An approved design for the signage
is shown in the Transportation Engineering Design Standards, available from the City of
Grand Junction Department of Public Works.
? For access routes 16 to 22 feet wide, No Parking signs are required along both sides of
the route.
? For access routes 22 to 28 feet wide, No Parking signs are required along one side of the
route.
? For Hammerhead Tees and Alternative Turnarounds, No Parking signs are required
along both sides of the area.
? For Cul-de-sacs, No Parking signs should be placed along the outside of the turnaround
area.

DESIGN STANDARDS
The following pages give examples of Grand Junction Fire Department approved roadway,
turnaround, and turning radius specifications. The last of these pages may be photocopied
onto a transparency as a template for Fire Department turn radius requirements. This is the
template used by the Fire Prevention Bureau when reviewing plans to determine proper
access and is based on the actual size of our fire fighting apparatus.

Other Fire Department Turnarounds and Clearances
Turnouts for Fire Hydrants: For emergency access routes less than 22 feet wide, where fire
hydrants are required along the route, a turnout area for fire trucks is required. The width of the
access road must be at least 20' in the area of the turnout. This turnout area is required so that
when a fire truck utilizes the fire hydrant in an emergency, the access route will still be available
for use by other emergency vehicles.
Intermediate Turnaround Areas: In cases where a single point of access exceeds 600 feet in
length, intermediate turnaround areas are required. The width of the access road must be at least
28 feet in the area of the turnaround. These areas allow emergency vehicles to turn around
without having to drive to the end of a long dead-end road. The intermediate turnarounds must
be provided at a maximum interval of every 500 feet.

MEMORADUM
To: Bruce Herbert- Macgregor Development Company
From: Lyddia E. Pritchard, Planning Director
Subject: Weavers Pond Roadway Improvements
Date: February 27, 2006
As part of the Special Use Permit approval process for Weavers Pond you provided a Site
Plan and Traffic Impact Analysis. The site plan was approved by the Board of
Commissioners. The roadway design improvements as provided by your firm and the
traffic engineer are integral to maintaining safe and timely access to northern Zebulon
residents. The minor thorough-fares shown on the attached exhibit provide for the access
and interconnectivity required in our Conservation Subdivision zoning. These same
roadway improvements were central to the Zebulon Board of Commissioners as
evidenced by the inclusion of these improvements as a condition of your Special Use
Permit.
Dual access points are a requirement of the 2000 edition of the International Fire Code.
The access points labeled on the attached exhibit (access 1 & access 2) are necessary to
provide for emergency ingress and egress to the 115 homes in the western portion of the
subdivision. Of course permitting with DWQ is necessary to implement the roadway
improvements your site plan approval requires. Please contact me with any suggestions
as to how a second entrance may impact your Special Use Permit.

direct approach of this roadway toward the north was a significant discussion point made
by the Board. Even at the cost of an encroachment to the buffers of the farm drainage
way, the town encourages that every effort be made to obtain approval for this roadway
crossing in the location shown on the attached exhibit.
Dual access points are a requirement of the 2000 edition of the International Fire Code.
The access points, labeled on the attached exhibit (access 1 & access 2), are necessary to
