B. Findings for Consideration
1. Traffic Impact Study
A traffic impact study for Slackrock Castle Greens Subdivisions was prepared by Washington
Group International. Below is a summary of the findings.
. New intersection Approach L (the intersection of Taconic Drive and Eagle Road) meets
ACHO warrants for a signal for the AM/PM peak hours. Approach L is currently predicted to
operate at LOS E with a delay of 4206 seconds during the AM peak hours and operate at
LOS F with a delay of 63.9 seconds during the PM peak hour. At Approach L a signal
should be added to improve the LOS. With the addition of the signal Approach L is
predicted to operate at LOS A with a delay of 7.9 seconds and 6.6 seconds during the AM
and PM peak hours respectively.
. According to signal warrant guidelines set forth in the Manual on Uniform Traffic Control
Devices (MUTCO); a signal is warranted at all existing arterial to arterial intersections for the
build out traffic volumes.
. Improvements to the Eagle Road and Amity Road intersection are necessary to
accommodate the background, and build out traffic volumes. The Eagle Road and Amity
Road intersection meets peak hour signal warrants. The intersection will operate under
capacity for the 2016 background and build out conditions if a signal and thru lanes are
added. The Blackrock and Compania developments are responsible for 26.82 % of PM
peak hour traffic impacts.
. New intersection Approach L (the intersection of Taconic Drive and Eagle Road) meets
ACHO warrants for a signal for the AM/PM peak hours. The arterial roadway should be
widened and a signal added to improve the LOS.
. Improvements to the Eagle Road and Amity Road intersection are necessary to
accommodate the background, and build out traffic volumes
. Future traffic analysis should be conducted to ensure that all internal roadways with front~on
housing have projected AOT of less than 1,000.
3 Blackrock Castle Greens MAZ.06-059/MPP-06-059
Staff Comment/Recommendation: Staff comments are provided by the District's Traffic Services
Division.
o The backgrpund growth rate of 5% is likely too high. Typically the background growth rates
should only be 1 %-2%, especially when compounded over several years such as with this
TIS where the build out year is 2016. The result is unrealistically high traffic volumes such
as the Amity/SH 69 intersection.
o An analysis of the traffic volumes on the internal roadways was not included in the TIS.
o Approach "L" (the intersection of Taconic Drive and Eagle Road) could make a good future
signal location if it connects to an adequate collector system.
o Based on the submitted traffic impact study, the applicant will be required to design and
construct a signal at the intersection of Taconic Drive and Eagle Road. Based on additional
information submitted by the applicant the signal is warranted with the development of the
599th lot or at 87% build-out. To ensure that the signal is installed and operating by the time
it is warranted, the applicant will be required to install the signal at the intersection of
Taconic Drive and Eagle Road with the final platting of the 500th lot. Further development
of the site will be prohibited until the signal is installed and functional.
2. Eagle Road
Right-of.Way Policy: District policy requires 96-feet of right-of-way on arterial roadways (Figure
72-F1 B). This right-of-way allows for the construction of a 5-lane roadway with curb, gutter, 5-foot
concrete detached sidewalks and bike lanes.
Sidewalk Policy: District policy requires 7-foot wide attached (or 5-foot detached) concrete
sidewalk on all collectorroadways and arterial roadways (7204.7.2).
Applicant's Proposal: The applicant has proposed to construct a 5-foot detached concrete
sidewalk abutting the site on Eagle Road.
Staff Comment/Recommendation: Dedicate 48-feet of right-of-way from the centerline of Eagle
Road abutting the parcel. The right-of-way purchase and sale agreement and deed must be
completed and signed by the applicant prior to scheduling the final plat for signature by the ACHD
Commission or prior to issuance of a building permit (or other required permits), whichever occurs
first. Allow up to 30 business days to process the right-of-way dedication after receipt of all
requested material. The District will purchase the right-of-way which is in addition to existing right-
of-way from available Corridor Preservation Funds.
The applicant's proposal to construct a 5-foot detached concrete sidewalk meets District policy.
The sidewalk shall be located a minimum of 41-feet from the centerline of Eagle Road. An
easement will need to be provided for any segment of the sidewalk located outside of the right-of-
way.
3. Taconic Drive
Residential Collector Policy: District policy 72-F1A, 7202.3.2 and 7202.3.5, requires that
residential collectors be constructed as 36-foot street sections with curb, gutter and 5-foot wide
concrete sidewalks with no front-on housing. The access restrictions for these street segments
should be stated on the final plat. Unless otherwise noted, parking should be prohibited on these
street segments. Coordinate the signage Program with District staff.
4 Blackrock Castle Greens MAZ-06-059/MPP-06-059
Island Policy: District policy 7202.7 and 7207,5 require islands to be constructed a minimum of 4-
feet wide with a minimum area of 100-square feet and designed to safely channel traffic. The
roadway on either side of the traffic island should maintain a minimum of a 21-foot street section.
Applicant's Proposal: The applicant has proposed to construct Taconic Drive as a 62-foot street
section with two 31-foot travel lanes, or two 21-foot travel lanes with a 20-foot center landscape
island, vertical curb, gutter, and a detached concrete sidewalk.
Staff Comment/Recommendation: Taconic Drive was originally created as part of Blackrock
Subdivision in 2004. At that time Taconic Drive was identified as a residential collector which would
be used to serve the future development of two large open space lots. The application for
Blackrock Subdivision went before ACHO's Commission on August 18, 2004. The Commission
determined that at that time Taconic Drive would not need to be constructed as a full residential
collector until the future development of the two large open space lots. The applicant constructed
the roadway with 24-feet of pavement, 3~foot gravel shoulders, 8-foot barrow ditch, and a 10-foot
asphalt path on one side of the roadway.
At this time the applicant will be required to construct Taconic Drive as a standard residential
collector with a 36-foot street section with vertical curb, gutter, 5-foot concrete sidewalk and no front
on housing within 50-feet of right-of-way. Parking will be prohibited on this roadway. Coordinate
the signage program with District Staff.
Due to the existing 10-foot asphalt path on the south side of Taconic Drive, and the applicants
desire to keep the path in its existing location, the applicant will be required to construct the 5-foot
concrete sidewalk only on the north side of Taconic Drive.
The applicant will be required to provide a minimum 21-foot street section on both sides of the
proposed center landscape islands.
4. Ashfall Way
Residential Collector Policy: District policy 72-F1A, 7202.3.2 and 7202.3.5, requires that
residential collectors be constructed as 36-foot street sections with curb, gutter and 5-foot wide
concrete sidewalks with no front-on housing. The access restrictions for these street segments
should be stated on the final plat. Unless otherwise noted, parking should be prohibited on these
street segments, Coordinate the signage Program with District staff.
Island Policy: District policy 7202.7 and 7207.5 require islands to be constructed a minimum of 4-
feet wide with a minimum area of 1 OO-square feet and designed to safely channel traffic. The
roadway on either side of the traffic island should maintain a minimum of a 21-foot street section.
Applicant's Proposal: The applicant has proposed to construct the roadway as a 36-foot street
section with curb, gutter, and 5-foot attached concrete sidewalk. The applicant has proposed to
construct two center landscape islands with 21-foot street sections on both sides.
Staff Comment/Recommendation: The applicant will be required to construct Ashfall Way as a
standard residential collector with a 36-foot street section with vertical curb, gutter, 5-foot attached
concrete sidewalks and no front on housing within 50-feet of right-of-way. Parking will be prohibited
on this roadway. Coordinate the signage program with District Staff.
The applicant will be required to provide a minimum 21-foot street section on both sides of the
proposed center landscape islands.

B. Findinas for Consideration
1. Traffic Impact Study
A traffic impact study for Blackrock Castle Greens Subdivisions was prepared by Washington
Group International. Below is a summary of the findings.
. New intersection Approach L (the intersection of Taconic Drive and Eagle Road) meets
ACHD warrants for a signal for the AM/PM peak hours. Approach L is currently predicted to
operate at LOS E with a delay of 4206 seconds during the AM peak hours and operate at
LOS F with a delay of 63.9 seconds during the PM peak hour. At Approach L a signal
should be added to improve the LOS. With the addition of the signal Approach L is
predicted to operate at LOS A with a delay of 7.9 seconds and 6.6 seconds during the AM
and PM peak hours respectively.
· According to signal warrant guidelines set forth in the Manual on Uniform Traffic Control
Devices (MUTCO); a signal is warranted at all existing arterial to arterial intersections for the
build out traffic volumes.
. Improvements to the Eagle Road and Amity Road intersection are necessary to
accommodate the background, and build out traffic volumes. The Eagle Road and Amity
Road intersection meets peak hour signal warrants. The intersection will operate under
capacity for the 2016 background and build out conditions if a signal and thru lanes are
added. The Blackrock and Compania developments are responsible for 26.82 % of PM
peak hour traffic impacts.
. New intersection Approach L (the intersection of Taconic Drive and Eagle Road) meets
ACHO warrants for a signal for the AM/PM peak hours. The arterial roadway should be
widened and a signal added to improve the LOS.
. Improvements to the Eagle Road and Amity Road intersection are necessary to
accommodate the background, and build out traffic volumes
. Future traffic analysis should be conducted to ensure that all internal roadways with front-on
housing have projected AOT of less than 1,000.
3 Blackrock Castle Greens MAZ-06-059/MPP-06-059
Staff Comment/Recommendation: Staff comments are provided by the District's Traffic Services
Division.
o The background growth rate of 5% is likely too high. Typically the background growth rates
should only be 1 %-2%, especially when compounded over several years such as with this
TIS where the build out year is 2016. The result is unrealistically high traffic volumes such
as the Amity/SH 69 intersection.
o An analysis of the traffic volumes on the internal roadways was not included in the TIS.
o Approach "L" (the intersection of Taconic Drive and Eagle Road) could make a good future
signal location if it connects to an adequate collector system.
o Based on the submitted traffic impact study, the applicant will be required to design and
construct a signal at the intersection of Taconic Drive and Eagle Road. Based on additional
information submitted by the applicant the signal is warranted with the development of the
599th lot or at 87% build-out. To ensure that the signal is installed and operating by the time
it is warranted, the applicant will be required to install the signal at the intersection of
Taconic Drive and Eagle Road with the final platting of the 500th lot. Further development
of the site will be prohibited until the signal is installed and functional.
2. Eagle Road
Right-of-Way Policy: District policy requires 96-feet of right-of-way on arterial roadways (Figure
72-F1 B). This right-of-way allows for the construction of a 5-lane roadway with curb, gutter, 5-foot
concrete detached sidewalks and bike lanes.
Sidewalk Policy: District policy requires 7-foot wide attached (or 5-foot detached) concrete
sidewalk on all collector roadways and arterial roadways (7204.7.2).
Applicant's Proposal: The applicant has proposed to construct a 5-foot detached concrete
sidewalk abutting the site on Eagle Road.
Staff Comment/Recommendation: Dedicate 48-feet of right-of-way from the centerline of Eagle
Road abutting the parcel. The right-of-way purchase and sale agreement and deed must be
completed and signed by the applicant prior to scheduling the final plat for signature by the ACHD
Commission or prior to issuance of a building permit (or other required permits), whichever occurs
first. Allow up to 30 business days to process the right-of-way dedication after receipt of all
requested material. The District will purchase the right-of-way which is in addition to existing right-
of-way from available Corridor Preservation Funds.
The applicant's proposal to construct a 5-foot detached concrete sidewalk meets District policy.
The sidewalk shall be located a minimum of 41-feet from the centerline of Eagle Road. An
easement will need to be provided for any segment of the sidewalk located outside of the right-of-
way.
3. Taconic Drive
Residential Collector Policy: District policy 72-F1A, 7202.3.2 and 7202.3.5, requires that
residential collectors be constructed as 36-foot street sections with curb, gutter and 5-foot wide
concrete sidewalks with no front-on housing. The access restrictions for these street segments
should be stated on the final plat. Unless otherwise noted, parking should be prohibited on these
street segments. Coordinate the signage Program with District staff.
4 Blackrock Castle Greens MAZ-06-059/MPP-06-059
Island Policy: District policy 7202.7 and 7207.5 require islands to be constructed a minimum of 4-
feet wide with a minimum area of 1 OO-square feet and designed to safely channel traffic. The
roadway on either side of the traffic island should maintain a minimum of a 21-foot street section.
Applicant's Proposal: The applicant has proposed to construct Taconic Drive as a 62-foot street
section with two 31-foot travel lanes, or two 21-foot travel lanes with a 20-foot center landscape
island, vertical curb, gutter, and a detached concrete sidewalk.
Staff Comment/Recommendation: Taconic Drive was originally created as part of Slackrock
Subdivision in 2004. At that time Taconic Drive was identified as a residential collector which would
be used to serve the future development of two large open space lots. The application for
Blackrock Subdivision went before ACHD's Commission on August 18, 2004. The Commission
determined that at that time Taconic Drive would not need to be constructed as a full residential
collector until the future development of the two large open space lots. The applicant constructed
the roadway with 24-feet of pavement, 3-foot gravel shoulders, 8-foot barrow ditch, and a 10-foot
asphalt path on one side of the roadway.
At this time the applicant will be required to construct Taconic Drive as a standard residential
collector with a 36-foot street section with vertical curb, gutter, 5-foot concrete sidewalk and no front
on housing within 50-feet of right-of-way. Parking will be prohibited on this roadway. Coordinate
the signage program with District Staff.
Due to the existing 10-foot asphalt path on the south side of Taconic Drive, and the applicants
desire to keep the path in its existing location, the applicant will be required to construct the 5-foot
concrete sidewalk only on the north side of Taconic Drive.
The applicant will be required to provide a minimum 21-foot street section on both sides of the
proposed center landscape islands.
4. Ashfall Way
Residential Collector Policy: District policy 72-F1A, 7202.3.2 and 7202.3.5, requires that
residential collectors be constructed as 36-foot street sections with curb, gutter and 5-foot wide
concrete sidewalks with no front-on housing. The access restrictions for these street segments
should be stated on the final plat. Unless otherwise noted, parking should be prohibited on these
street segments. Coordinate the signage Program with District staff.
Island Policy: District policy 7202.7 and 7207.5 require islands to be constructed a minimum of 4-
feet wide with a minimum area of 1 OO-square feet and designed to safely channel traffic. The
roadway on either side of the traffic island should maintain a minimum of a 21-foot street section.
Applicant's Proposal: The applicant has proposed to construct the roadway as a 36-foot street
section with curb, gutter, and 5-foot attached concrete sidewalk. The applicant has proposed to
construct two center landscape islands with 21-foot street sections on both sides.
Staff Comment/Recommendation: The applicant will be required to construct Ashfall Way as a
standard residential collector with a 36-foot street section with vertical curb, gutter, 5-foot attached
concrete sidewalks and no front on housing within 50-feet of right-of-way. Parking will be prohibited
on this roadway. Coordinate the signage program with District Staff.
The applicant will be required to provide a minimum 21-foot street section on both sides of the
proposed center landscape islands.
5
Blackrock Castle Greens MAZ-06-059/MPP-06-059
5. Internal Streets
Right-oJ-Way Policy: District policy 7204.4.1 and Figure 72-F1A requires 50-feet of right-of-way
on local streets. This right-of-way allows for the construction of a 2-lane roadway with curb, gutter
and 5-foot wide concrete sidewalks.
36-foot Street Section Policy: District policy 7204.4.2 states, "developments with any buildable lot
that is less that 1-acre in size will typically provide streets having a minimum pavement width of 32-
feet with curb, gutter and sidewalks. The total street width shall be 36-feet from back-of-curb to
back-of-curb. Concrete sidewalks shall be a minimum of 5-feet in width unless they are separated
from the curb 5-feet or more in which case the sidewalk shall be a minimum of 4-feet in width.
Island Policy: District policy 7202.7 and 7207.5 require islands to be constructed a minimum of 4-
feet wide with a minimum area of 1 OO-square feet and designed to safely channel traffic. The
roadway on either side of the traffic island should maintain a minimum of a 21-foot street section.
Applicant Proposal (Internal streets): The applicant is proposing to construct the internal streets
as a 34-foot street section with rolled curb, gutter, and 5-foot attached concrete sidewalk within 50-
feet of right-of-way. Additionally, the applicant has proposed to construct several center landscape
islands throughout the site.
Staff Comment/Recommendation: The applicant's proposals meet District policy. The applicant
will be required to provide a 21-foot street section on both sides of proposed center landscape
islands.
6. Roadway Offsets
Roadway Offset Policy: District policy 7204.11.6, requires local roadways to align or offset a
minimum of 300-feet from an arterial roadway (measured centerline to centerline).
District policy 7204.11.6, requires local roadways to align or offset a minimum of 150-feet from a
residential collector roadway (measured centerline to centerline).
District policy 7204.11.6, requires local roadways to align or offset a minimum of 125-feet from
another local roadway (measured centerline to centerline).
Applicant's Proposal: The applicant has proposed to construct one roadway (Taconic Drive) to
intersect Eagle Road located approximately 370-feet south of the north property line (measured
property line to centerline).
Staff Comment/Recommendation: The applicant's proposal meets District policy and should be
approved with this application.
7. Stub Streets
Stub Street Policy: District policy 7203.5.1 states that the street design in a proposed development
shall cause no undue hardship to adjoining property. An adequate and convenient access to
adjoining property for use in future development may be required. If a street ends at the
development boundary, it shall meet the requirements of sub section 7205, "non-continuous
streets." District policy 7205.5 states that stub streets will be required to provide intra-neighborhood
circulation or to provide access to adjoining properties. Stub streets will conform with the
requirements described in Section 7204.5, 7204.6 and 7204.7, except a temporary cul-de-sac will
not be required if the stub street has a length no greater than 150-feet. A sign shall be installed at
the terminus of the stub street stating that, "THIS ROAD WILL BE EXTENDED IN THE FUTURE."
6 Blackrock Castle Greens MAZ-06-059/MPP-06-059

Request for Reconsideration of Commission Action
1. Request for Reconsideration of Commission Action: A Commissioner, a member of ACHO
staff or any other person objecting to any final action taken by the Commission may request
reconsideration of that action, provided the request is not for a reconsideration of an action
previously requested to be reconsidered, an action whose provisions have been partly and
materially carried out, or an action that has created a contractual relationship with third parties.
a. Only a Commission member who voted with the prevailing side can move for
reconsideration, but the motion may be seconded by any Commissioner and is voted on by
all Commissioners present.
If a motion to reconsider is made and seconded it is subject to a motion to postpone to a
certain time.
b. The request must be in writing and delivered to the Secretary of the Highway District no later
than 3:00 p.m. on the day prior to the Commission's next scheduled regular meeting
following the meeting at which the action to be reconsidered was taken. Upon receipt of the
request, the Secretary shall cause the same to be placed on the agenda for that next
scheduled regular Commission meeting.
c. The request for reconsideration must be supported by written documentation setting forth
new facts and information not presented at the earlier meeting, or a changed situation that
has developed since the taking of the earlier vote, or information establishing an error of fact
or law in the earlier action. The request may also be supported by oral testimony at the
meeting.

occupied the moment before it was voted on originally. It will normally be returned to ACHD
staff for further review. The Commission may set the date of the meeting at which the
matter is to be returned. The Commission shall only take action on the original matter at a
meeting where the agenda notice so provides.
e. At the meeting where the original matter is again on the agenda for Commission action,
interested persons and ACHO staff may present such written and oral testimony as the
President of the Commission determines to be appropriate, and the Commission may take
any action the majority of the Commission deems advisable.
