Introduction
Overview
Modus has been commissioned by BDH Properties Pty Ltd to provide traffic and transport advice in
response to the Noosa Council Information Request (IR) regarding the proposed development located
at 3 Avocet Parade, Peregian Beach. A copy of the Noosa Council IR is provided at Appendix A.
This Traffic Engineering Letter has been produced by Modus in response to the Noosa Council IR
items relating to the traffic and transport components in support of the proposed development.
Council Further Advice Item 1 – Access
Council Commentary
Council has concerns with the proposed vehicle access for the southern unit. The access is located in close
proximity to the bend in the road. Council is concerned that suitable sight lines/distances cannot be
provided due to the geometry of the road, existing services, existing and proposed vegetation within the
road reserve and the property, property fencing.
Provide plans that demonstrate that suitable sight lines/distances can be provided for the proposed vehicle
access for the southern unit. The plans must include existing services, existing and proposed vegetation
within the road reserve and the property, property fencing.
If suitable sight lines/distances cannot be achieved provide an amended design for the development.

Modus Response Modus’ response to Item 1 is outlined in the subsequent report sections. AVOCET PARADE ROAD CONDITIONS The proposed southern unit will achieve vehicular access onto Avocet Parade, which comprises the following conditions: N Posted speed limit of 50 km/hr, N Carriageway width of 7.0m, N 4.5m verge along the southern site boundary frontage. PRACTICAL SPEED LIMIT While it is noted that Avocet Parade comprises a posted speed limit of 50 km/hr, it is reasoned that throughbound vehicles along Avocet Parade at the site frontage will travel at lower speeds to manouevre through the 90-degree bend. On this basis, Modus has undertaken a B99 swept path assessment (provided at Appendix B) which confirms the maximum speed that a throughbound vehicle approaching from the north can practically manouevre through the 90-degree bend is 30 km/hr. Therefore, the assessment herein has been undertaken for a frontage road speed of 30 km/hr at the site frontage. STOPPING SIGHT DISTANCE In accordance with Australian Standards AS2890.1, the minimum vehicle sight distance requirement is stipulated for a frontage road speed of 40 km/hr or greater. Provided that no vehicle sight distance requirement is stipulated for a frontage road speed of 30 km/hr, Modus has instead undertaken a Stopping Sight Distance (SSD) assessment in accordance with the Austroads Guide to Road Design Part 3 guidelines, which is defined below: Traffic Engineering Letter – IR Response 3 Avocet Parade, Peregian Beach -2-
Page 3
As such, the SSD has been assessed from the Avocet Parade northern approach for a throughbound vehicle to appropriately react and break upon observing a vehicle exiting from the vehicle access for the southern unit. For this assessment, the following parameters have been adopted: N Design Speed (V): 30 km/hr N Reaction Time (RT) 2 seconds, N Coefficient of Deceleration (d): 0.46, N Longitudinal Grade (a): 0% Therefore, the minimum SSD required for a vehicle approaching from the northern along Avocet Parade is 25.0m The minimum SSD required for southern unit driveway is provided at Appendix C, and is illustrated below on Figure 1. Figure 1 Minimum SSD Requirement Therefore, the minimum SSD of 25.0m is able to be accommodated along Avocet Parade, such that an unimpeded driver line of sight is provided for a southbound vehicle along Avocet Parade to react and brake for a vehicle exiting the southern unit driveway. Furthermore, it is reasoned that the southern unit driveway will have an incredibly low traffic generation (to the degree of one vehicle in the peak hour period), and hence the likelihood of an outbound vehicle exiting the driveway while a southbound vehicle approaches from the north will be incredibly low.

RECOMMENDED MITIGATION MEASURES
To further ensure sufficient visibility is provided between throughbound vehicles and outbound
vehicles at the southern driveway, Modus recommends the following mitigation measures be
accommodated:
N Implement ‘concealed driveway’ signage along the Avocet Parade verge along the western
boundary frontage that is orientated to the north,
N Clear any vegetation within the verge near the 90 degree bend.
The abovementioned mitigation measures are illustrated on Figure 2 below.

APPLICATION DETAILS Application No. MCU24/0120 & OPW24/0143 Street Address: 3 Avocet Pde Peregian Beach Qld 4573 Real Property Description: Lot 320 P 93113 Planning Scheme: Noosa Plan 2020 (25 September 2020) 2. INFORMATION REQUIRED The information requested is set out below: Issue — Access Council has concerns with the proposed vehicle access for the southern unit. The access is located in close proximity to the bend in the road. Council is concerned that suitable sight lines/distances cannot be provided due to the geometry of the road, existing services, existing and proposed vegetation within the road reserve and the property, property fencing. Information Required 1. Provide plans that demonstrate that suitable sight lines/distances can be provided for the proposed vehicle access for the southern unit.

Issue — Frontage Works The alignment of the proposed kerb and channel does not appear to smoothly transition between sections. It is noted that the alignment of kerb and channel across the frontage of the subject site was approved as part of an earlier approval for the subject site (MCU20/0024 & OPW20/0055 — SCG Consulting drawing 30031-OW4.1 revision A). The application been referred to Council's Infrastructure Team for comment and the footpath along the frontage of the subject site is not required and must be removed from the relevant plans. Information Required 2. Provide amended civil works plans that are in accordance with SCG Consulting drawing 30031-OW4.1 revision A. 3. Remove footpath from the relevant plans. Issue — Pergola The proposed pergola/landscaped arbor within the front boundary setback of Unit 1 is considered an unnecessary structure which contributes to the builds bulk to the street, inconsistent with the established character and further restricts landscaping opportunities. Information Required 4. Remove the structure from the front setback. Issue — Landscaped Setback Acceptable outcome AO12.2 of the Medium Density Residential Zone Code talks to the front 6 metres being landscaped open space, with swimming pools, not protruding more than 1 metre above ground level, can be setback 2 metres. The proposed setback varies from 1.6- 1.7 metres, an increased setback is sought by the Codes. Information Required 5. Provide increased soft landscaping setback of a minimum of 2 metres. Issue — Front Fences and Walls The architectural plans show the front fence achieving a maximum height of 2.65 metres. This is not considered compatible with the street character and does not achieve Performance outcome PO17. PO17 Front fences and walls are designed and sited to: a) contribute to the attractiveness of the streetscape; b) be compatible with the existing streetscape character; c) avoid interference with movement of surface stormwater; d) allow for casual surveillance of the street; e) provide planting in front of solid fences and walls; and f) ensure plantings between the front fence and the footpath does not create an impediment for pedestrians using the footpath. Information Required 6. Provide revised fencing plan and address the above-mentioned outcome. Issue — Plot Ratio The below highlighted areas constitute gross floor area.

e The identified laundry areas are % enclosed with the presentation of an enclosed outdoor room and function as such. This approach is consistent with recent Tribunal findings which support Council’s interpretation. The spaces are to be included in the developments gross floor area. e The landing/steps contained on the lower and upper levels do not provide access between levels and therefore are to be included in the developments total gross floor area. Information Required 7. Provide revised gross floor area calculations in compliance with the Performance outcome PO11 of the Medium Density Residential Zone Code and administrative terms. Issue - Site Cover Plan DA.19 shows void areas as being excluded from the developments site cover. While the final calculations do not appear to exclude these areas, please note the development’s coverage is calculated from birdseye view. Information Required 8. Provide revised plans showing the developments site coverage from a birdseye view rather than per storey for clarity. Issue — Landscaping e Noting the extent of fill on the site, it is likely that the areas of landscaping along the northern and eastern side boundary of Unit 1 will not be capable of supporting the establishment of species. e There are several areas identified on the site included in soft landscaping calculations that is solely gravel i.e., outdoor seating area and area surrounding the swimming pool of U2. These impervious areas do not contribute to soft landscaping. soft landscaping means trees, shrubs, grass, garden beds and impervious surfaces that occur naturally such as rock outcrops. Soft landscaping is not located on top of a constructed slab or other structure and is capable of supporting the establishment and growth of canopy trees as well as other species. The term does not include swimming pools or impervious surfaces such as driveways, vehicular access lanes, vehicle parking and manoeuvring areas, pathways, stormwater structures, tennis courts, decks, balconies, roof terraces and the like. It also does not include areas over which balconies cantilever unless there is a vertical height of 4 metres between the ground and the balcony to allow for significant planting. Document Set ID: 23290066 Page 3 of 4 Version: 2, Version Date: 10/10/2024

Information Required 9. Provide revised landscaping plans noting the above-mentioned items. 9.1. Increase the landscaping width between the side boundaries to suitably accommodate and support the establishment of soft landscaping. 9.2. Remove outdoor seating area from contributing to soft landscaping calculations. Item for clarification Council is seeking clarification of a notation on SCG drawing number 0336-SW1.1. The notation is located near the south-eastern corner of the site and refer to “stacked Ausdrain” but the arrow points to a pipeline and no “ausdrain cell” is indicated on the plans at this location. Information Required 10. Provide clarification regarding the notation and provide an amended plan. 3. DUE DATE FOR RESPONSE TO INFORMATION REQUEST The due date for providing the requested information is 10 January 2024. Email your response to [email protected]. Please advise Council of your response to this information request in accordance with section 13 of the Development Assessment Rules. If you do not provide a response before the due date, it will be taken as if you have decided not to respond to the information request and Council will continue with the assessment of your application. 4.
