Teitei Drive Summary of Option Costs
Dear Vini
Proposed Teitei Development
The development proposes a staged subdivision for an initial 46 lot, 44 residential home subdivision in
Stage 1, with further extension possible if later stages proceed. Entrance to Stage 1 is approximately 25m
beyond the existing Teitei Drive terminus (see Figure 1).
Figure 1
Proposed Teitei Subdivision with 46 lot Stage 1 highlighted
As part of the subdivision Resource Consent, an Integrated Transport Assessment has been produced. In
part, this considered the Road Safety Ef ects of the proposed access via SH49 and existing Teitei Drive.
This found that the proposed development would operate within recognised safety parameters.
The Power of Commitment
GHD Limited
GHD Limited was subsequently asked to undertake a high level examination and compare the costs of
providing an access road into the development from the existing Teitei Drive, or forming a new road and
intersection from Raetihi Ohakune Road. Both options would be constructed within the existing road
reserve.
The two options can be simplified to:
•
Option A: Utilising and extending the existing Teitei Drive by 25m, designed to incorporate
development such as the subdivision. This option wil cost approximately $55,000 to join to the
subdivision; or
•
Option B: Constructing a new road from the development, extending approximately 455m to
intersect with Raetihi Ohakune Road. This option wil cost over $1M, without contingency. This
option has slight safety disbenefit due to higher speeds and predicted predominant turning
movements.
Teitei Drive and Carrot Park Facility
Teitei Drive was designed in 2017 and constructed in 2018, specifically:
• To provide access to, and provide parking for the Carrot Park;
• To provide a slow shared zone in the Carrot Park car park, with a mix of vehicular traffic and
pedestrians, including a mix of more vulnerable pedestrians of a wide age range profile;
• To include toilet and camper waste facilities; and
• To enable and provide for future development of the land beyond the facility. At the time this future
use was stil being considered, but included potential for a large hotel facility or as a residential
development.
The road was terminated at its present location to specifically allow and cater for this future development,
with the curved entry and road width designed to slow vehicles on entry to the facility.
Teitei Development
The development proposes an initial 46 lot, 44 residential home subdivision in Stage 1, with further
extension possible if later stages proceed. Entrance to Stage 1 is approximately 25m beyond the existing
Teitei Drive terminus (see Figure 1).
There are effectively two options for entry into Stage 1 of the development: Option A - Extension from
Current Teitei terminus; or Option B - create new road from Raetihi Ohakune Road. Option B would
encroach slightly on the rugby grounds, particularly the area currently used for parking. It would also require

Ohakune Road (see Figure 2).
