The Committee reports that: PART A - MATTERS REQUIRING A COUNCIL DECISION
1. CHRISTCHURCH CITY TRAFFIC AND
PARKING ALTERATION BYLAW 1996
Officer responsible Author Traffic Manager Brian NeillThe purpose of this report is to amend the principal Christchurch City Council Traffic and Parking Bylaw to enable the Council to introduce multi-bay parking meters in the city (draft attached - buff paper). The proposed alteration bylaw will also cover an addition to the one way street schedule and update the definition of a `vehicle' to comply with the wording in the Transport Act 1962. MULTI-BAY PARKING METERS
Some months ago the Council commenced a trial of multi-bay parking meters in a section of Oxford Terrace adjacent to Colombo Street and in High Street between City Mall and Manchester Street. The trial has been very successful and plans are in hand to install more multi-bay meters in the city. Early next year both Bedford Row and the section of Colombo Street between City Mall and St Asaph Street will be upgraded with new kerbs and channels, footpaths and landscape features. The Council's aim is to enhance these areas as part of an upgrade of city centre streets with planted areas and cobblestone paving where appropriate. Environmentally one parking meter servicing between two and eight spaces will improve the streetscape as well as providing a more `user friendly' means of controlling parking. Tenders are presently being sought for the supply of multi-bay parking meters for both Colombo Street (between Hereford Street and Moorhouse Avenue) and in Bedford Row where angle parking will be introduced.
1 Cont'd The Bylaw change involves the redefinition of a `parking meter' to include the multi-bay meter. Clause 3 of the Principal Bylaw is to be altered by adding the words `single bay or multi-bay' to the definition of a parking meter. Clause 9 of the Principal Bylaw is to be altered by revoking clause 2(b) for the provision of metered areas and substituting a new clause 2(b) to include provision for multi-bay meters. DEFINITION OF A VEHICLE A `vehicle' means "a contrivance equipped with wheels, tracks or revolving runners upon which it moves or is moved; but does not include: (d) A child's toy, including a tricycle and cycle, provided, in either case, no road wheel (including any tyre) has a diameter exceeding 335 mm. Clause 3 of the Principal Bylaw is to be further altered by changing the diameter of a road wheel from the presently stated 335 mm to 35 cm in clause (d) of the definition of a `vehicle'. LAKEWOOD DRIVE
Construction will commence early next year on the reconstruction of the eastern end of Lakewood Drive at its intersection with Burwood Road. This work is in accordance with a Council hearing decision where it was decided to introduce a short section of one way street to resolve traffic problems at the Burwood Road intersection and deter motorists from using Lakewood Drive as a through route between Burwood Road and Lake Terrace Road. This work was endorsed by the Burwood/Pegasus Community Board and will complete a long standing commitment of the Board of resolve a difficult traffic issue. An addition is to be made to the fifth schedule of the Principal Bylaw by adding the following paragraph: 34. Lakewood Drive in an easterly direction from a point 128 metres from its intersection with Stillwater Avenue to its intersection with Burwood Road.
CONCLUSION
Due to statutory requirements the Council will not be in a position to commence special order proceedings for the bylaw changes until its meeting in February 1996. It is proposed to enact the parts of the Christchurch City Traffic and Parking Alteration Bylaw 1996 relating to the multi-bay meter provisions and the changes in the meaning of `vehicle' in April 1996 seven days after the March meeting of the Council where the special order is likely to be confirmed. Recommendation: That the Council endorse the proposed changes to the Christchurch City Traffic and Parking Bylaw 1991.
2. TRADE WASTES CHARGES FOR 1995/96
Officer responsible Author Manager, Waste Management Unit Neville Stewart Corporate Plan Output: Waste Management Reticulation, Pumping, Trade Waste Services and Christchurch Treatment Works, pages 9.2.8 to 9.2.11.The purpose of this report is to institute Special Order procedures to increase Trade Waste charges as detailed in the 1995/96 Annual Plan and in accordance with previous Council resolutions. Legislation requires that Trade Waste charges be set by Special Order and because the charges are to rise in 1995/96 it is necessary that the Council passes the appropriate resolutions to allow the Special Order process to commence. This report provides background for the Committee and sets out the required resolution. Following amalgamation, an examination of the manner in which Trade Waste charges had been calculated showed that dischargers were receiving significant concessions on the true cost of transporting and treating the trade wastes. A report presented in 1992 showed that the current charges would need to rise by 44.7%-53.1% to be at the level that would cover actual costs, and this calculation excluded cost of capital. The Operations Committee agreed, in discussion with the Manufacturers Association, that Trade Wastes dischargers be required to reach a level of charges that would cover costs (exclusive of costs of capital) over a five year period as follows: Agreed Charges (set by Council September 1992)
91/92 92/93 93/94 94/95 95/96 96/97
Volume 25.71 28.00 30.49 33.20 36.15 39.37
($/litre/min)
BOD ($/kg/day) 38.17 41.22 44.52 48.08 51.90 56.04
SS ($/kg/day) 37.15 40.00 43.08 46.40 49.96 53.79
Calculations based on the actual 1994/95 costs show that the 1996/97 target is now:
Volume ($/litre/min) 39.76 BOD ($/kg/day) 58.37 Suspended Solids ($/kg/day) 62.34
Thus the sequence of increases set in 1992 in respect to Volume and BOD charges are still very close to being correct if the 1996/97 target is to be achieved. The Suspended Solids charge is significantly affected by biosolids disposal costs. In 1994/95 the farm costs rose from $60,000 per year average to $304,000. While this increase is attributed to sharply reduced cattle sale prices and is unlikely to be repeated this year, the biosolids disposal costs next year are expected to rise by some $300,000. If close to 100% recovery of suspended solids costs is to be achieved it will be necessary to continue to increase the rate for this charge for a further two years beyond 1996/97. Any decision on this matter can be left until next year. The charges set out under 1995/96 in the above table have been announced in the Annual Plan and it is recommended that they now form the basis of the Special Order.
2 Cont'd Recommendation: That Special Order procedures be instituted in accordance with Section 494 of the Local Government Act 1974 to set Trade Waste charges for the 1995/96 year effective from 1 April 1996 as follows: For dischargers with volume greater than five cubic metres per day:
$
Rate of Discharge $/litre/min 36.15
BOD $/kg/day 51.90
Suspended Solids $/kg/day 49.96
such charges being inclusive of GST.
3. PREBBLETON SEWAGE DISPOSAL
Officer responsible Author
Manager, Waste Management Unit Mike Berry, Liquid Wastes
Engineer
Corporate Plan Output: Waste Management Liquid Waste Advance
Planning Budget, page 28.
The purpose of this report is to consider a request received from the
Selwyn District Council for Prebbleton to connect to the city's sewerage
system.
BACKGROUNDThe Selwyn District Council has requested a decision on whether or not the Christchurch City Council is prepared to accept sewage from Prebbleton and if so under what conditions. Prebbleton is currently served by septic tanks, most having boulder pit disposal. Field tile lines are proving ineffective because of the impermeability of the sub-soil. Current disposal is also considered a contamination risk to domestic water supply wells in the area. The Selwyn District Council has had a Project Team investigate the need for sewerage systems in townships in the Eastern Selwyn area. The report produced by a consortium of Royds Consulting and Lincoln Environmental recommends that for Prebbleton the best practical option is to reticulate the township and pump the effluent to the Christchurch system. A similar request for the possible acceptance of Lyttelton's sewage was considered by the Council nearly two years ago. It was resolved then: `That the Council support cross boundary solutions when they provide the best overall environmental outcome at an acceptable cost, such cost being correctly apportioned.'
3 Cont'd As it transpired the Banks Peninsula District Council decided to go it alone and build their own Plant at Battery Point (although construction has still to begin). However it is assumed that this policy still holds and that this question can be considered by the City Services Committee on the basis of practicality and feasibility. SELWYN DISTRICT COUNCIL REQUEST
The request from the Selwyn District Council is for the acceptance of a 25 litre per second pumped intermittent flow from Prebbleton township including Meadow Mushrooms Limited. The 25 l/s pumped flow corresponds to an accepted design peak sewage flow for an ultimate township population of 2,000. This figure assumes residential development of the present Meadow Mushrooms area. The present population of Prebbleton is approximately 530. The wastewater volume discharged annually by Meadow Mushrooms is equivalent to another 135 persons.
FEASIBILITY
Connecting Prebbleton to the city's sewer system would be technically straightforward. Sewage could be pumped approximately 2.4 km along Springs Road to Halswell Junction Road and discharged into nearby Pump Station 67, situated 160 metres north along Halswell Junction Road. The Prebbleton pump station and pressure main would need to be sized to practically minimise the age of the effluent discharged and its related potential to release odour. With the discharge being direct to Pump Station 67 rather than the downstream gravity reticulation, the effect on peak flows downstream will be minimised. This is because Pump Station 67 will not pump any faster with Prebbleton connected, just for longer periods. The downstream route to the Wastewater Treatment Plant is mainly via the Southern Relief Sewer and is gravity all the way to Pump Station 1. While the downstream pipeline is considered reasonably full in places, it does not overflow in wet weather (unlike the city's Northern Relief Sewer and southern trunk system). Even if this situation were to change in future, it is considered that the Prebbleton flow would not be a significant contributing cause. Current reticulation planning to cope with expected city growth over the next 20 years includes tapping off flow from the Southern Relief Sewer near Hagley Park, and diverting it into a new duplicate relief sewer running to a new enlarged No. 11 Pump Station (serving southern Christchurch). Implementation of this plan will make the transportation of Prebbleton's flow inconsequential. 3 Cont'd CANTERBURY REGIONAL COUNCIL POSITION
The Canterbury Regional Council is concerned with failing septic tanks in Prebbleton and the effect this may have on public health and the environment. They see no problem with Prebbleton connecting to the city's system provided the Treatment Plant discharge to the Estuary continues to comply with the terms and conditions of our current notified discharge authorisation. With the addition of the Prebbleton flow the discharge will still comply. However, putting the proposed ultimate flow from Prebbleton into perspective, it represents less than 0.5% of the average annual volume received by the Treatment Plant in recent years. It also corresponds to less than six months of recent city growth. APPORTIONING OF COSTS
Connecting Prebbleton to the city's system will involve no capital outlay for the city. Maintenance of the township's new sewerage system and pressure main to Pump Station 67 would also be the Selwyn District Council's responsibility. The preferred method of charging the Selwyn District Council for the Prebbleton connection is an annual charge based on the actual volume discharged. This provides an incentive to minimise the discharge. The cubic metre unit cost can readily be calculated from the cost of the city's Liquid Waste Activity (obtained from the Annual Budget) and the annual flow received by the Treatment Plant. It is estimated that the charge will be approximately 30 cents per cubic metre which is similar to that paid by Christchurch ratepayers for liquid waste reticulation and treatment. In addition, Prebbleton residents will still have to meet the full costs of the township's reticulation and pumping. The proposed method of charging will require the discharge from Prebbleton to be measured. It is suggested that the Selwyn District Council be responsible for the flow measurement with periodic checking of the equipment by the Christchurch City Council. CONCLUSION
The request from the Selwyn District Council to accept sewage from Prebbleton is considered reasonable, especially considering the township's close proximity to the city's system. A metered pumped connection to Pump Station 67 is technically straightforward. The effect on the downstream reticulation and Estuary is considered to be insignificant in both the short and long term. The Canterbury Regional Council is keen to see the sewage disposal concern in Prebbleton addressed. Recommendation: That the Council agree to the Selwyn District Council's request to accept sewage from Prebbleton, under the following conditions that: 3 Cont'd 1. The township's flow is pumped to Pump Station 67 in Halswell Junction Road at a maximum rate of 25 l/s. 2. Total annual volume discharged shall not exceed 250,000 cubic metres (the volume expected from the ultimate 2,000 population). 3. The Selwyn District Council is responsible for all capital and maintenance costs up to the point of the discharge including flow measurement. 4. The Selwyn District Council will be charged annually based on the measured volume discharged. The cubic metre unit cost will be determined from the full cost of the city's Liquid Waste Activity obtained from the Annual Budget, and the annual volume of sewage received by the Treatment Plant. 5. Conditions 1 to 4 above be the basis of a detailed agreement between the two Councils for a Cross Boundary Service and that this agreement be formally entered into by each Council.
PART B - ITEMS DEALT WITH BY THE COMMITTEE AND
REPORTED FOR INFORMATION ONLY
4. ELECTION OF DEPUTY CHAIRMAN Councillor G L Freeman was elected Deputy Chairman.
5. MEMBERSHIP OF CO-ORDINATING COMMITTEE
FOR TRAFFIC SAFETY Councillors M F Fahey and D J O'Rourke were appointed members of the Subcommittee at the meeting of the Council on 6 November 1995 with a further member to be appointed. The Committee has appointed Councillor D N Buist. The Committee was advised that the Commissioner of Police would address the meeting of the Subcommittee held on 1 December 1995. It was requested that the following issues be raised at that meeting: Speed Cameras
Breathalysers
Colour of Traffic Enforcement Vehicles 6. SAFETY (ADMINISTRATION) PROGRAMME The application for Safety (Administration) Programme community projects funding and allocation of Police hours for Christchurch which had been completed in consultation with interested organisations and community groups had been approved by the Traffic Safety Co-ordinating Committee. The application was endorsed by the City Services Committee.
7. QUARTERLY REPORT OF POLICE ACTIVITIES:
PERIOD ENDED 30 SEPTEMBER 1995 Inspector Garth Hames reported on Police traffic enforcement activities. The Committee was advised of the installation of temporary pedestrian crossings outside schools approved by the Land Transport Safety Authority as a trial. A survey of schools would be undertaken to ascertain the support of the new proposals. The Committee is concerned at the use of wheel clamps in private car parks as an enforcement measure. Having previously received assurances from Christchurch Public Hospital authorities that wheel clamps would not be used in the hospital car parking areas, it was noted that wheel clamps were being used. It was resolved that options for legal action against the hospital authorities currently using wheel clamps in the hospital car parks be reported direct to the Council meeting on 13 December.
8. STRATEGY FOR CHILDREN A progress report on the Traffic Unit's proposed strategy to improve road safety for children in Christchurch was received. It was resolved that provision be made in the draft 1996/97 budget for additional funding for investigation of safe routes to schools for children and cyclists training.
9. SPEED LIMIT REVIEW The Committee discussed the method of consultation for the proposed changes to existing speed limits. A flow chart for the consultation process was recommended to the Committee. The chart with amendments requested by the Committee is attached (blue paper). It was resolved that the consultation method for the review of speed limits on roads in the city be adopted.
10. CONTRACT NO. 95/96-168
HAZELDEAN ROAD KERBS AND CHANNELS ETC.
(SELWYN STREET TO ANTIGUA STREET) The Committee's approval of a tender for the Hazeldean Road kerbs and channels (Selwyn Street to Antigua Street) was sought. Tender prices were received as follows:
10 Cont'd
McGinty Contractors $217,780.45 Works Operations Unit (CCC) $217,786.00 Calcon Asphalt Ltd $233,484.00 Timarsh Contractors $235,562.50 Local Construction Ltd $239,776.00 Waddell Holdings Ltd $244,202.10 J S Rodgers Ltd $261,048.51 Blair Construction Canterbury Ltd $267,000.00
All prices exclude GST. It was resolved that the lowest price conforming tender of McGinty Contractors for the sum of $217,780.45 be accepted. However, in considering this report Committee members raised the issue of the Council's Works Operations Unit tender being only $5.55 less than the successful tenderer. Committee members asked if costs of supervision had been taken into account and if a weighted attributes system could be employed in assessing tenders of this value. Members were arguing that the best value for the ratepayer may not be achieved in the current tender process. The Director of Operations has been asked to report to the Committee on the tendering issues discussed.

The Committee received reports on the road safety awareness campaigns run by the Council. Committee members' concern about the position of the cycleway in Armagh Street near New Regent Street would be reported to the Central City Committee. The Legal Services Manager has been requested to report direct to the Council on options for legal action against Christchurch Hospital Authorities on the use of wheel clamps. The Committee is concerned that previous requests by the Council and assurances given that wheel clamps would not be used have not been actioned. 12.2 Queen Elizabeth II Drive
The Committee received a report on round-about research which is being carried out at the junction of Queen Elizabeth II Drive and Marshland Road where the existing round-about is experiencing some capacity problems during peak traffic. Road markings on the approach to and within the round-about have been modified as part of the study. 12.3 Woolston/Burwood Expressway
Assessments are being undertaken to improve the opportunity for funding of the Woolston/Burwood Expressway including a study of forestry traffic impacts.
