2. Bike Northland Proposal

Reporting officer Paul McDonald (Parks and Recreation Manager)

Date 20 November 2012

Vision, mission and values

This item is in accord with Council’s vision, mission and values statement as the development of a cycling facility is central to a sustainable lifestyle and maximises the use of our unique environment. Cycling adds to the vibrancy of the district and is a recreational activity for all ages and families. The establishment of the bike park shows a commitment to communication with the cycling groups and putting the customer first through planning processes. The idea of multiple sports clubs sharing the facility is innovative and Council shows visionary leadership through supporting these programmes in plans it approves.

Local Government Act 2002 – The four well-beings

Cultural Cycle sports are available to all cultures in a public space and enhance the districts focus on clean and healthy lifestyles.

Economic Cycling sports and events at Pohe Island, and associated retail and industry generate millions in economic value to Whangarei.

Environmental Cycling sports are low environmental impact and encouraging cycling reduces dependency on vehicles.

Social

A hub for cycle sports and multiple sports provides a central city sporting precinct. Whangarei has a proud sporting culture and the social benefits of sport to young people requires stepping stones through various sports, as youth leave traditional field sports they often take up sports such as running and cycling.

Background Bike Northland is an incorporated society and the Regional Sporting Organisation for cycling sports in Northland. Cycling sports have no current permanent base for operations within Northland and this item discusses a proposal from Bike Northland to provide such a base at Pohe Island, inclusive of the building known as the old Paper Reclaim facility.

Council approved the use of the facility for cycling sports in the William Fraser on Pohe Island Management Plan and has already entered into the lease negotiations for the building with Bike Northland. Bike Northland and Council partnered in building the BMX track in the new location to be beside the Resort building. That track successfully held the Nationals and North Island championships which according to the report from Bike Northland provided an estimated positive economic impact of $8,000,000.

Proposed Bike Park Bike Northland propose a partnership with Council on the basis of forming a mix of club and public use facilities. They request support for the formalisation of a lease and the development of the building to be fit for purpose. The building is in a poor state and requires a lot of work to repair. Bike Northland propose a lease for the land where the building is, and some land for adjacent activities (car parks and grounds). Bike Northland proposes purchasing the building for $1 to enable them to make applications for external funding for the development of the facility. Further to the development of the building is the proposed bike park to include, learn to ride facilities, riding paths, the BMX track and a cycling hub which all the cycling interests would be a part of.

Bike facilities are included in the development plans for Pohe Island within Council’s 2012 LTP budgeted at approximately $4.5 million over three years 2015 to 2018. The detail of which facilities this budget is allocated to is being finalised. Pohe Island development did include costs for improvements to the old paper reclaim building and development of cycling facilities. Therefore, Council would benefit from any external funding which could supplement existing budgets. To that end Bike Northland request that Council confirm that budgets include costs for developing bike facilities. Council has also already invested in the relocation of the BMX track to its current location. The BMX track was mostly paid for by Bike Northland and BMX

sponsors, and is open to the general public. Staff propose a detailed development plan be developed by Council staff to include all the uses of Pohe Island with further detail on cycling facilities and budgets.

Council plans currently include the new Hatea Bridge and the proposed Looped Walkway which provide for cycle activity, with links to Onerahi cycle ways, and the cycle loop from Town Basin.

Partnerships

New funding priorities and criteria from external funders favour the development of facilities which benefit multiple users. The modern word for this is Sportsville. The Sportsville at Fraser Park in Upper Hutt combines many sporting codes such as rugby, hockey, cricket, squash, softball and baseball. The concept provides for one space to offer mixed use and maximum use of the facility, reducing duplicity and creating a vitalised centre. Bike Northland are prepared to play a lead role in planning with the view of creating a sustainable facility, and to that end they suggest a detailed planning report, assessing the viability of the building for maximising its use across several other sports which are compatible. There has been initial interest from running and cycling groups. Bike Northland requires Council support for this approach so that external funders see a strong partnership approach.

Conclusion

Bike Northland is seeking Council support regarding:

1. The sale to Bike Northland of the old Paper Recycling Building for $1.00 to be developed into a building “fit for purpose” to meet the needs of a Sportsville type model.

2. The ground lease of the site to Bike Northland.

3. Both the above would require performance criteria to be met in relation to prompt development of the building and securing funding from external parties. Council Staff recommend that a MOU and lease be developed with Bike Northland to achieve the above.

Recommendation 1. That the information be received.

2. That a MOU be developed with Bike Northland.

3. Council approves in principle the sale of the old Paper Reclaim facility on Pohe Island to Bike Northland for $1.00.

4. That a ground lease be developed to Bike Northland and that the lease provide for performance reporting to Council.

5. Support for Bike Northland is given to partner with other groups and to apply for funding from external parties, subject to any multiple use agreement having final approval of the Infrastructure and Services Committee.

6. That staff report back with the final lease and Memorandum of Understanding for Council approval.

Introduction-

Bike Northland (BN) is an incorporated society. Its formation was assisted by Sport Northland in

2007. Its establishment and approach has been used as a model by Sport NZ (previously known as

SPARC).

Bike Northland (BN) is the recognised RSO for cycling in the Whangarei and Northland Area. It has

engaged with various councils including the WDC and NRC with regard to cycling, particularly

planning and management issues. It regularly attends the relevant meetings co-ordinated by these

and other relevant agencies in the Northland Region.

The organisation submitted to the Pohe Island Management Plan to establish a Bike Park that could

service the greater Whangarei Community and be ultimately a regional and national asset. The

future Bike Park was to be based around the old “Resort” building site that Bike Northland wishes to

occupy and this is well discussed and supported in the final draft of the Pohe Island Management

plan that was adopted by the Whangarei District Council.

The first steps in the development of the Bike Park were taken when we successfully co-ordinated

the relocation and construction of a new BMX track, at the request of the Council, in close proximity

to the old “Resort” building. We not only managed the project but successfully obtained 1:1

sponsorship from the commercial world. The community as a result has a “world class” facility -

($845,000.00 approximate worth). It has already

- hosted a National BMX Championships event (2009). The economic impact from

this was conservatively estimated at $4,836,040.00

- hosted NZ and other International athletes as a training and preparation venue.

-been allocated the 2012 North Island Titles event. Estimated economic impact will

be $3,600,000.00

Bike Northland’s management were sponsored for leadership training by Sport Northland and

SPARC. Bike Northland continues to be a funded sports agency by Sport Northland and other key

parties.

The Old “Resort” Building

Current condition

The old Resort building at Pohe Island is not in a great state of repair with some settlement in the floor and foundations and wind damage to the roller doors that has left the majority of them inoperable. The roof and wall claddings are due for renewal as leaks are now appearing. What value does it have? The steel frame work should be able to be used as a base for a reconditioned building on the site and it is on one of the few areas of Pohe Island that are suitable for a building. Having been built around 20 years ago settlement of the site under the building has now mostly occurred. The site will be relatively stable or more stable that elsewhere on Pohe Island. What does the future hold for it? Appendix 1 was a draft proposal that was given to the WDC Mayor late in 2011 to distribute for comment. It was a concept document we were hoping would give life to a working relationship between the WDC and Bike Northland and the planning for the funding and development of the Bike Park and Building as a multi-use facility. Although it is now out of date if we are to progress the redevelopment of the building many of the steps listed in it are still applicable going forward. What needs to happen now

1) Support. Hopefully the WDC still supports the use and future development of the Resort building by Bike Northland as detailed in the Pohe Island Management plan. This is essential if we are to succeed going forward. The Global Economic Crisis has made it somewhat more difficult to attract funding. However organisations like the ASB Community Trust after putting funding for infrastructure projects on hold has opened up again and are working strategically with other funding organisations so their contributions deliver the maximum return achievable. They have just released a new funding strategy which at face value will be good for us. However they need to see some buy in from the local community and support from the Council will be valuable to the return of a favourable outcome from an application to them.

2) Planning. We need to commission a more in depth study into the best possible mix of different potential user groups if we are to attract any significant funding for the development of the building in today’s economic environment. We were looking to secure some Sport NZ active communities funding to engage someone to do this but that wasn’t supported by the WDC CEO, Mayor and senior councillors we met with. We are now looking to fund this from profits from other activities like the Fred Ogle Memorial Ride that was gifted to Bike Northland by Paul Fancy at Avantiplus Whangarei.

3) Design. We have approached Hawthorne and Geddes and HB Architecture who have assessed the building and forwarded proposals to us for their further engagement. HB Architecture sketched concepts for us some time ago that are included in the last pages of this document but the final designs will be shaped by the needs of the use groups that can best work together in this facility. We are reluctant to commission any further work by either of these companies until we have a lease signed that secures Bike Northlands occupancy of the site.

4) Implementation. Although a construction schedule of works for both the Building and wider Bike Park were suggested in Appendix 1 this would need to be tailored to match funding as it becomes available.

Summary

Bike Northland would like to work with the council to develop recreational cycling facilities on

Pohe Island that are available for the majority of the time for the general public to use. At the

moment it looks like we are being told to fund and develop a community asset on our own.

We would like to purchase the old Resort Building and lease the land in the area around it.

To attract funding for these sort of projects now we do have to look at providing a home base

and services for a number of groups that are not currently affiliated to Bike Northland in our

plans to develop the building.

As we did with the BMX track Build we will add significant value to any funding support from

the Council for a Bike Park or the redevelopment of the building. We also stand a far greater

chance of securing funding from other sources if there is a commitment from the council to

support the projects as well. However as detailed in the latest LTCCP we are a few years away

before any funding for the development of Pohe Island will be available.

We are concerned that the council now has other plans for the use of the building and the area

around it. If these concerns are justified that would be extremely disappointing when reflecting

on the effort that we put in to locating the new BMX track to where it is so all the cycling

activities could be in close proximity to each other and all the cycling codes could be base in the

old Resort building.

The number of cyclists in Whangarei is set to increase over time as cycling is normalised again

in Primary Schools through the Bikes in Schools projects we have started to implement. We

expect that this will naturally lead to a greater demand for Recreational Cycling facilities and

Transport infrastructure in the Whangarei District that accommodates all cyclists. We are still

willing to work with the council to meet these demands and hope that the council is willing to

work with us.

Appendix 1

Proposal regarding the development of the recycle facility building and Bike Park

1) Partner with WDC, Sport Northland and Bike NZ and submit EOI to SPARC for Active

communities funding. EOI due before 07/11/11 full applications by 02/03/12 if EOI accepted.

#2 and #3 will need to happen before final application submitted.

2) BN to survey in depth all other groups that have expressed an interest in sharing a facility at

Pohe Island to determine their current and future needs. Clubs formally confirming initial

expressions of interest. Media exposure of those working together.

3) Review information and establish a brief that best meets the needs of the majority of potential

users. Provisionally, toilets, showers, gym, meeting rooms, offices, service shop could meet

the wide variety of sports codes who have expressed initial interest. Media exposure of the

proposal i.e. the concept.

4) BN to commission a feasibility study to determine viability of their fit into a multi code sporting

community operating from the developed resort building and the long term sustainability of

the project . Plans established to maximise the usage of the facility and ensure its future

financial viability.

5) BN to purchase resort building from WDC for $1.00.

6) BN and WDC to agree to a management approach. Provisionally areas around building and new

BMX track to be leased and a wider area as a right to occupy or similar arrangement for more

extensive shared facilities.

7) BN to further establish relationships with key partners to assist with progression of project.

8) BN to have plans drafted and project costs established.

9) WDC to commit funding in LTCCP to assist with funding of project and to challenge for funds

available elsewhere for cycling e.g. NZTA

10) BN to submit funding applications to ASB Community Trust, Lotteries etc.

11) Works programme drafted.

12) Construction phase. Current suggested programme.

Stage 1- Buildings steel portal frames levelled, new floor poured, building made secure,

toilets and showers installed and BMX 8m SX start ramp constructed. i.e. basic facilities

and BMX track fully operational by 30 June 2012, prior to 2012 BMX North Island Titles

events (expect economic impact of $3.6 m to the community)

Stage 2- New roofing and cladding, interior fitted out (midlevel floor, office, meeting,

storage and function rooms and facilities)

Stage 3- Additional Bike Park facilities developed. Learn to ride/criterion course, Cyclocross

and MTB obstacles/training course, dirt jump/freestyle course and event administration

buildings.

N.B. BN’s ability to successfully bid for high profile International UCI BMX Supercross events

and realise the benefits from these will be greatly enhanced if the Stage 2 construction and

the administration buildings in Stage 3 are scheduled for completion prior to events possibly

being held in 2014, 2015 and 2016. BN would be looking to secure a 2 or 3 year contract

with the UCI to host these International events in the years preceding the 2016 Olympic

Games.

13) Additional programmes and events will be delivered as funding and facilities become available.

3. Unsealed Dust Control Options

Reporting officer J Devine (Roading Manager)

Date 29 October 2012

Vision, mission and values

This item is in accord with Council’s vision, mission and values statement as it supports sustainable land management and transportation, providing a quality environment and protecting those assets that contribute to community health and well being.

Social The proposal is equitable and fair for the community

Introduction This agenda presents for Council’s consideration a review of a number of options for dust control on unsealed roads, and the results of a number of trials undertaken by Council over recent years.

Background On 10 October 2012 the Infrastructure and Services Committee adopted a seal extension programme for 2012-15, to utilise the $600,000 per annum allocated in the recently approved Long Term Plan (LTP). This will see three roads sealed over the next 3 years, Whangaruru North Road, McKinley Roa and Old School Road. This represents only 6.9km of Council’s 800km unsealed network, so the issue of dust on unsealed roads will remain an issue for residents for some time into the future.

Seal Extension Policy Previously Council has adopted a Strategic Seal Extension policy (see attachment 1), which gives priority to projects that could attract NZTA subsidy funding, but also allowed for some Ratepayer subsidised projects if these were economic.

Council generally undertakes seal extensions for two primary reasons: • to extend the sealed network; or • for dust control.

Seal Extensions Generally when Council undertakes a seal extension project the roads are designed for a 25 year pavement life, which is a requirement for NZTA subsidy funding. Generally the design must also meet Council’s own Environmental Engineering Standards Code for road geometry and pavement. This is the same requirement imposed on subdivisions and developers.

Council’s current procurement process uses the design and build methodology where the contractor designs the project to meet the specified requirements.

Dust Control Seals Council’s Strategic Seal Extension Policy allows for short sections of dust coat seals in front of isolated residential houses on unsealed roads as a ratepayer subsidised seal extension. Normally we seal in 100m lengths, the ratepayer contribution is set at 20% of $30,000 per 100m, and the programme has operated on a first come first served basis.

Alternatives for Dust Control – Waste Oil In 2003 Fulton Hogan, (Gisborne), undertook a research project that showed:

14


“... that most conventional dust suppressant agents used in this country generally only last 2-3 months, and then have to be reapplied. Most of the commercialised materials have not proven to be cost effective, but their continued use has been necessary to satisfy users and local residents. In some regions, waste oil has been (and still is?) applied by residents and local authorities alike, because of its low cost and good performance, compared to the alternatives.

However the use of waste oil as a dust suppressant is now not considered environmentally acceptable because of the heavy metal and other contaminants contained in the oil, and if the application of oil is not maintained, the dust and waste oil can end up polluting surface-water systems and vegetation. Thus, its use is prohibited by some regional authorities in New Zealand, with more banning its use each year.”

The Northland Regional Council has banned the use of waste oil on unsealed roads in Northland.

Commercial Alternatives Generally commercial dust suppressants come in three different types; • Lignosulphonates – a waste material from the pulp and paper industry • Soya bean extracts • Specialised emulsified bitumen products.

Fulton Hogan undertook trials of these products in the Gisborne area in 2003.

The graph shows the amount of dust generated from each trial section before and after application and in the following months. The results show the emulsion product out-performed the other two products, which after one month were performing as if they were untreated.

The trials were repeated by the Dunedin City Council and in Mid Canterbury during 2003. The results of all these trials:

“...highlighted the short comings (short life cycle, high cost and so on), of the commercialised palliative remedies. The consensus was that none of the remedies had been successful but a replacement for waste was still required.” – (2009 NZTA Research Report 368).

15


WDC Trials 2010 During the summer of 2010 Council trialled the use of a commercial dust control product “Gravel Lock” on metal road sections in 5 locations around the District. • A section in Wright Road subject to heavy logging truck traffic worked well but didn’t last • Franklin Road, a shaded hill section failed immediately • Tudehope Road worked well but didn’t last • Attwood Road, a hill section didn’t last • Springfield Road, also a hill section was trialled with gravel-loc then a chip seal and the pavement

failed.

Pavement failure Springfield Rd Hill Section

The Otta Seal Technique The Otta seal is a low-cost seal option used in developing and third world countries for seal extension and resurfacing treatments. The technique is called “Otta Seal” because it was first developed and trialled in the Otta Valley in Norway, in 1963, as an inexpensive seal extension treatment.

Otta seals use a soft residue binder to bind together a locally sourced aggregate. Normal bitumen binders become hard and brittle when set. The soft binder tolerates higher deflections, and is less likely to crack than normal seals and minor cracks can self seal during warmer temperatures.

NZTA undertook a trial of Otta seals in 2005/6 comparing the lifecycle costs of different dust control treatments. For this technique to be successful as a dust minimisation treatment in NZ, it needed to be cost-competitive with the waste oil treatment. But it could only do this on a life cycle cost basis as the Otta seal is initially a more expensive treatment.

16


2009 NZTA Research Report 368 The graph shows that over a five year period, an Otta seal technique is the low-cost option. It is less expensive than doing the normal maintenance treatment (i.e. doing nothing about dust), but only if indirect and intangible costs are included, such as dust contamination of adjoining land, council costs for dealing with complaints, and vehicle operating costs.

However the low maintenance and construction costs for normal maintenance activities (doing nothing about dust) make it an attractive short term option to do the minimum, deal with the complaints, and ignore intangible costs.

Otta Seals vs. Standard Seal Extensions The 2009 NZTA Research Report states:

“..The Otta seal technique used in these trials was developed specifically for dust minimisation, and is not a suitable seal extension or traction seal technique. If the pavement is improved for a seal extension, then a normal chipseal would be a more appropriate surfacing. However the cost of constructing and sealing small isolated sections of pavement would be prohibitive, more than 5 times the cost of the Otta seal technique, and also they would require a second coat seal within 5 years of construction”.

The cost of a 100m dust coat seal in accordance with Council’s dust coat seal policy is approximately $30,000 with an expected life of 25 -30 years.

Otta seals, based on Councils’ 2011 trials, cost about $6-7000 per 100m ($11/m2) with an expected life of five plus years subject to traffic and general ground conditions.

WDC Otta Seal Trials Last summer in December 2011, Council trialled 3 sites in the District with Otta seals:

• Ody Road Hill – steep uphill section 10-11% grade, 80m long, 8-9m wide, 150 vpd • Lamb Road – section from garage to end of childcare property, flat, 75m long, 8m wide, 150 vpd • Lovell Road Bridge approaches – flat, 2x 40m long, 5.5m wide, 100 vpd.

18


Lovell Rd Bridge approaches – July 2013 – potholes around abutment out to 10m where shape is flat. Some cracking evident on western side on wheel tracks

Fabric Seals Another low cost dust suppression treatment is use of fabric seals. This technique consists of constructing layers of bitumen, a tough specialised fabric, more bitumen and then sealing chips on shaped gravel roads. The costs for this technique is about 1/3 of standard sealing costs, i.e. $10,000 per 100m, and has a life expectation of ten years subject to traffic volumes and ground conditions.

Fabric Seals

19


Summary Commercial additives for dust suppression have not been successful and have proved not to be an economic solution.

Otta seals and maybe fabric seals are an alternative for Council’s dust coat sealing programme in isolated low traffic roads. The cost for these treatments could be reduced to 1/3 to 1/5 of a standard sealing cost but with reduced life meaning earlier renewal times.

Standard seal extensions include the development of proper pavements to achieve long term pavement life and allow Council to get the best value for the investment, i.e. the best whole of life cost option.

Delegations and Policy Manual 2010

Trim No. 10 / 97690

Strategic Seal Extension Policy Background

Council currently has a seal extension and upgrading programme of approximately 25 kilometres per year. A majority of these works are subsidised 50% by Transfund New Zealand from petrol taxes. To qualify for funding, these works must meet an economic criteria set down by Central Government.

The order in which the works are completed is dependent on the economic benefit derived (i.e. the greater the benefit the higher the priority given to the works).

Council has for a number of years developed a Strategic Seal Extension Programme to manage the needs and funding for seal extensions across the District.

Strategy Aims and Objectives

The aims of Council’s Strategic Seal extension Programme are:

To develop a seal network over a reasonable planning period which meets the needs of the District at an affordable cost.

Criteria to be taken into account include:

� To complete the sealing of the arterial road network � To develop links between communities � To meet the requirement for no ratepayer to be more than 5 kilometres from a sealed road � To seal roads affected by logging or other significant heavy traffic, if that is the best solution for

upgrading that particular section of road � To consider dust control sealing, if that fits as the best solution for upgrading a particular section

of road � To maximise the level of Transfund subsidy and/or ratepayer contribution in the development of

the annual seal extension programme.

It is accepted that a fairly high proportion of District roads will remain unsealed into the foreseeable future. There are some road links, which clearly need completion early in the programme, and others, which, although desirable, are less of a priority.

At the current level of funding, Council has up to 10 years of sealing works to complete the sealing of arterial road networks alone. Council also recognises that benefits can be achieved from sealing additional roads in the network and have developed the following policy.

Additional Roads that may achieve a B/C

It is recognised that roads other than the major arterial roads within the District may achieve a benefit/cost and attract subsidy for seal extension. This is mainly due to increased traffic flows, resulting from an increase in rural/residential development, tourism, holiday traffic on coastal roads and the effects of logging or other significant heavy traffic, all resulting in higher maintenance cost for these roads.

Recognising that there are benefits to both the public and Council in sealing some of these roads they will be considered for sealing if the projects can achieve a benefit/cost ratio and subsidy funding from Transfund NZ.

This is a long term strategic plan and it is unlikely that the majority of low volume rural residential roads will be sealed in the near future as traffic counts are currently too low to attract the required subsidy. Council does, however, support a ratepayer subsidised seal extension programme each year. The details of Council policy are shown below:

Ratepayer Subsidised Seal Extension

1 That Council continues with a subsidized seal extension programme with the following criteria used as the basis for the acceptance of applications to participate in that programme.

2 Applications to be made the year preceding the work to allow funding to be provided in Council’s estimates

3 Applications in any one year to be priorities taking into account as one of the criteria the degree they support Council’s overall seal extension strategy and programme.

4 The priorities list of applications to be submitted to the Workings and Services Committee for approval.

5 All applications to be supported by at least 80% of the landowners in the area of benefit.

6 Council’s contribution towards the cost of the work to be limited to its share of the initial widening and pavement strengthening.

7 Ratepayers to pay the full cost of sealing the road after the pavement is strengthened.

Dust Cost Seals

Dust Coat Seals for isolated residential houses on unsealed roads will be considered as ratepayer subsidised seal extensions, subject to the following additional criteria:

8 Applications will be considered for funding if the road in question is unlikely to be included in the seal extension programme.

9 Applications in any one year will be prioritised according to the severity of the dust problem and the volume and type of traffic on the road.

10 Ratepayers will be required to contribute $2,000 (plus GST) or 20% of the upgrading and sealing costs per 100m of sealing (for a typical length of 100m of seal per dwelling).

Minor Roads Seal Extension Programme

It is also recognised that some roads service community or Council owned facilities, and contributions from residents may not be available or appropriate.

Council will undertake a minor road seal extension programme to seal these minor roads and car parking facilities that support the community but do not attract Transfund subsidy or ratepayer contributions.

Priorities for Funding

The priorities for funding the strategic seal extension programme will be:

i To complete the sealing of the arterial road network.

ii To seal additional road that may achieve a B/C ratio and attract subsidy funding.

iii To meet Council share of ratepayer subsidised seal extensions, including dust coat seal applications, where the project will support Council’s overall seal extension strategy and programme.

iv To undertake a minor roads seal extension programme to seal minor roads and/or car park facilities, which will benefit the wider community.

The Roading Manager will be responsible for developing a roading programme each year for Council’s consideration, providing for the best use of the current total funding package for seal extension, reseals, rehabilitation, strengthening and incorporating Council’s policy on seal extension; asset management plan requirements and the impact of forestry on Council roads with the objective to provide the best solution for each section of road.
