Les Amis Asks Quebec Environment Minister for Help

Les Amis du parc Meadowbrook has written Quebec Environment Minister Benoit Charette, asking him to intercede in a plan that would harm one of the the few remaining open sections of the historic Saint-Pierre River, which runs through the Meadowbrook property.

This small waterway has been found to be contaminated by sewage coming from the Toe Blake Connector. Tests revealed the ultimate source of the pollution comes from cross-connections in underground pipes in Cote St Luc and Montreal West. The City of Montreal has known about this situation since 2002. It did a study of the collector in 2014, but the problem continues.

A Quebec Superior Court judge has given the City of Montreal until the end of 2019 to stop the pollution of the Saint-Pierre. As a result, the city decided to temporarily divert the collector until the crossed connections have all been fixed.

Les Amis expressed grave concerns about this proposal. While it would reduce the pollution, this would harm the plants growing along the river’s banks during dry spells. It would also affect the entire hydrographic system in the area, since the river drains the spring runoff that accumulates nearby, attracting migrating waterfowl to the area.

Les Amis asked the minister whether he could ask for impact studies on the effects of the planned deviation, and whether he could also force the three municipalities concerned to find a less environmentally damaging solution.

Five other environmental organizations also signed the letter while the CRE-Montreal will send its own letter to the minister on the subject.

The text of the letter is included below, in French only.

 

Le 6 mars 2019.

M. Benoit Charette

Ministre de l’Environnement et de la Lutte contre les changements climatiques

Objet : Demande de certificat d’autorisation pour la déviation du collecteur Toe Blake à Montréal

 

M. le ministre,

Je suis directrice du groupe environnemental Les Amis du parc Meadowbrook.

Depuis trente ans, notre groupe défend du développement immobilier un terrain de golf de 57 hectares qui se trouve à cheval sur l’arrondissement de Lachine et la ville de Côte-Saint-Luc dans le sud-ouest de Montréal. Le terrain n’est pas propice au développement, étant entouré – et traversé – par des rails de chemin de fer. Notre objectif est d’en faire un parc nature accessible à tous. Nous avons d’ailleurs obtenu la désignation Grand espace vert ou récréatif pour le terrain en 2015 dans le Plan métropolitain d’aménagement durable (PMAD).

Nous sommes préoccupés du sort de la rivière qui traverse ce terrain, un des rares endroits à Montréal où l’on peut encore voir l’historique rivière Saint-Pierre qui coulait autrefois du flanc de la Montagne jusqu’à Verdun et qui a été ensuite raccordée à la petite rivière Saint-Pierre qui, elle, se jette dans le Saint-Laurent à la Pointe-à-Callières, le berceau de la ville de Montréal.

Nous ne voulons en aucun cas que cette rivière soit enfouie ou canalisée : nous aimerions plutôt la voir réhabiliter. Nous avions d’ailleurs applaudi la décision de la Cour supérieure de juin 2018 (dossier 500-17-079150-135, ci-joint) qui forçait la ville de Montréal à cesser de polluer la rivière, mais les choses ne sont jamais si simples.

La Ville de Montréal sait depuis au moins 2002 que le ruisseau est contaminé grâce aux études du Réseau de suivi des milieux aquatiques (RSMA). La pollution provient en fait du collecteur Toe Blake qui va de la Ville de Mont-Royal, traverse les villes de Côte-Saint-Luc, Montréal et Montréal-Ouest pour se déverser sur le golf Meadowbrook à la hauteur du parc Toe Blake dans Montréal-Ouest. Le collecteur est contaminé par des raccordements croisés situés dans les villes de Côte-Saint-Luc et Montréal-Ouest. La Ville de Montréal avait d’ailleurs entrepris en 2014 une analyse très rigoureuse du collecteur, regard par regard (160 prélèvements en tout) et avait repéré 167 raccordements fautifs à Côte-Saint-Luc et 51 à Montréal-Ouest (copie du rapport est ci-joint).

Nous avons travaillé avec la Société pour vaincre la pollution (SVP) qui, à partir de ce rapport, a repéré les secteurs où se trouveraient les raccordements inversés de même que les adresses des propriétés touchées. Nous avons remis ces adresses aux trois municipalités concernées.

Nous avons plaidé auprès des villes de Montréal, Côte-Saint-Luc et Montréal -Ouest, de même qu’à l’Agglomération, mais n’avons obtenu que des réponses partielles. Après des tests de fumée, la ville de Côte-Saint-Luc n’aurait rien trouvé (!) tandis qu’après des tests de rhodamine, la ville de Montréal-Ouest aurait réglé neuf cas de raccordement croisé et réorienterait ses efforts de réfection des rues à l’avenir vers les rues où se trouverait le plus grand nombre de raccordements problématiques. Ne pourrait-on pas à tout le moins reprendre l’échantillonnage de l’étude du collecteur Toe Blake dans les secteurs les plus polluants afin de savoir une fois pour toutes ce qu’il en retourne ?

Pour faire vite –la Cour supérieure a donné à la Ville de Montréal jusqu’à  la fin de 2019 pour stopper la pollution –Montréal a décidé de détourner le collecteur Toe Blake en amont de la rivière, de manière temporaire à ce que l’on nous dit, jusqu’à ce que les raccordements croisés soient corrigés.

Le fait de détourner ainsi le collecteur par temps sec nous préoccupe à plusieurs titres. Il réduit à n’en pas douter la pollution du cours d’eau, mais entrainerait cependant l’assèchement de la rivière pendant ces périodes, privée qu’elle serait de son alimentation.   Une telle mesure causerait des dommages importants à la flore riveraine qui s’est implantée depuis que le propriétaire a cessé de tondre la pelouse jusqu’au bord de l’eau. Il y a plus cependant : c’est tout le système hydrographique qui serait affecté, puisque la rivière draine le terrain qui inonde au printemps, à la grande joie des oiseaux migrateurs qui en ont fait un arrêt dans leur périple annuel. Avouez qu’un tel spectacle n’est pas banal en pleine ville de Montréal. En vertu de l’article 31.34 de la Loi sur la qualité de l’environnement (LQE), ne pourrait-on pas demander des études sur l’impact d’une telle déviation? Le ministère ne pourrait-il pas aussi en vertu de l’article 31.33 de cette même loi forcer les trois municipalités concernées à se concerter pour trouver une solution moins dommageable?

De nombreux autres groupes environnementaux et communautaires appuient notre démarche comme vous pouvez le constater aux signatures qui accompagnent cette lettre. Nous voulons tous sauver la rivière, la tendance voulant que les villes rouvrent les cours d’eau enfouis par le passé afin d’alléger les problèmes de surverse et la facture de traitement des eaux (voir notre article http://lesamisdemeadowbrook.org/uncategorized-fr/daylighting-les-rivieres/?lang=fr)

Nous vous remercions de prendre en considération nos inquiétudes et nous en remettons à votre bon jugement pour empêcher la perte de l’un des derniers tronçons encore visibles de la rivière Saint-Pierre.

Veuillez agréer, monsieur le ministre, nos sentiments les plus distingués

Volunteers Needed!

Les Amis du Parc Meadowbrook is a lively, dynamic group whose mission is to transform Meadowbrook, a 57-hectare green space that straddles the city of Cote St. Luc and the borough of Lachine, into an urban heritage nature park accessible to all. The group is also involved in a great many ways in the fight to preserve green spaces on the Island of Montreal.

If you would like to make a contribution and bring your special expertise to the table, here are a few suggestions:

Communications Committee

If you are a WordPress or a Wiki wizard, we would like to hear from you for help with our website (www.lesamsidemeadowbrook.org) and our ecomap project (www.montrealecomap.com). We could also use some help on our Facebook (www.facebook.com/sosmeadowbrook) and Twitter (@ParcMeadowbrook) pages.

Les Amis are celebrating their 30th anniversary in 2019. We have many projects in mind. So if you would like to lend us a hand, you are most welcome! Money, as always, is the crux of the matter, so any fundraisers would also be welcome.

Guardians of Meadowbrook

This is a special initiative to protect Meadowbrook until it becomes a nature park. A number of projects are under consideration: bird boxes and feeders (Meadowbrook is well known to birdwatchers), cross-country skiing and snowshoeing in winter, access routes to the area, etc.

Good research, collaborative and negotiating skills are required in this case.

Sauvons la Falaise

Les Amis and Sauvons la Falaise (www.sauvonslafalaise.ca) are partner organisations.  Sauvons la Falaise’s mission is the protection of the Falaise Saint-Jacques ecoterritory that stretches 4 kilometres from Montreal West to Westmount along St. Jacques Boulevard.

Here is a special assignment, one best suited to geography buffs. We need to make a map of the Falaise with GPS coordinates. For those with a more political bent, we also need volunteers to follow the proceedings of the Bon voisinage Turcot meetings in NDG and the Sud-Ouest, as well as volunteers to attend municipal council meetings.

 

Please contact us at lesamisdemeadowbrook@gmail.com to find out more and help us make Meadowbrook accessible to all!

Thank you for your interest!

 

Daylighting Rivers

by Sally Cole

Daylighting:  A Global Trend Transforming Cities in the 21st Century

Waterways were once the lungs and arteries of urbanization.  Yet, most of the world’s cities have buried their founding streams under concrete or incorporated them into sewer networks under roads and expressways and housing and industrial developments.  Burying rivers has degraded habitats and increased pollution and the costs of water treatment and waste management.  It has also increased flooding and damages due to flooding that are increasing with climate warming.

What is Daylighting?

Daylighting is the process of removing concrete and culverts that are covering and obstructing original rivers, creeks and drainage paths and of revitalizing original wetlands and drainage flow.  Daylighting is part of a larger flood management and water treatment strategy and an attempt to redress the thoughtless neglect of cities that continue to pollute their rivers.

Why Daylight?

Bringing back lost urban rivers by removing culverts and integrating flowing rivers into cities again –daylighting – is part of a global movement to rediscover urban rivers in cities worldwide.  In the 21st century, forward-thinking cities and citizens – in London, New York, Seoul, Zurich, Berkeley – are daylighting their historic rivers in a bid to halt pollution end environmental degradation, and increase the liveability and future viability of their cities.

These cities report that their daylighting projects have:

– reduced water treatment costs

– aided flood management

– increased property values

– revitalized natural habitats with the return of indigenous plants, trees, fish, birds    and other wildlife

– added greenbelts, bike routes and walking paths that have produced connectivity within and between neighbourhoods

– increased social health and volunteer citizen engagement;

– created tourism and related business opportunities.

Montreal has an opportunity to join this progressive urban trend and invest in the future of our city by daylighting our historic St. Pierre River, the river on which our city was founded.

The Lachine Canal bike path crosses where the bed of the St. Pierre used to be.

Models of Successful Daylighting in Cities Around the World

Since 2009, London has opened up more than 17kms of waterways.  Throughout the U.K. – where daylighting is known as deculverting — municipal governments have incorporated deculverting into legislation on water and flood management.

Zurich, which has undertaken more daylighting than any other city in the world, has tracked, documented and analyzed the combined social, environmental and economic benefits.  The city has found the economic rewards of daylighting in reduced wastewater treatment costs.  Channeling clean water out of sewers and back into original rivers and streams reduces the volume of water that flows to sewage waste management facilities for treatment.  Zurich also reports an increase in public desire and civic engagement to recapture lost spaces and to improve the quality of life in the city.  https://www.weforum.org/agenda/2017/09/daylighting-is-a-new-trend-that-s-transforming-cities/

The daylighted Cheonggyecheon Stream in Seoul, South Korea, transformed a polluted, urban, crime-ridden wasteland into a major flood relief channel and a 10.9km public downtown recreation space that has revived the city centre and attracts more than 60,000 visitors each day.  Restoration of two historic bridges over the restored river, along with managed changes in the downtown traffic system, has reduced by 2.3% the volume of cars entering downtown Seoul each day and increased bus and subway use.  Along with reducing air pollution, daylighting the Cheonggyecheon has created an environment with clean water and natural habitats that also helps to cool temperatures in the downtown area to 3.6 C lower than other parts of Seoul.  https://en.wikipedia.org/wiki/Cheonggyecheon

Daylighting the Sawmill River in Yonkers, New York, has created a vibrant green corridor in the city and revitalized the downtown.

http://www.sawmillrivercoalition.org/whats-happening/daylighting-the-saw-mill-river-in-yonkers/.

In an effort to reduce future flood risk, after hundreds of basements flooded in a 1999 storm, the city of Dubuque, Iowa invested in an engineering study.  The key recommendation of the study was to restore, through daylighting, a one-mile section of the buried Bee Creek that flows under the city centre. https://www.americanrivers.org/conservation-resource/daylighting-streams-breathing-life-urban-streams-communities/

To manage frequent flooding in the downtown area of Kalamazoo, Michigan, city engineers found that it was cheaper to daylight the buried Arcadia Creek than to rebuild and expand the century-old culvert system.

Friends of Meadowbrook Are Daylighting the St Pierre River!

The first step in daylighting is to map the route and extent of a buried river under the city.  The route of the St Pierre River is well known — from its source on Mont Royal through its various tributaries and down to its original outlet into the St. Lawrence River at Pointe-à-Callière.

The St. Pierre River in 1834. source: carte de l’ile de Montreal, 1834, by A. Jobin, BAnQ http://numerique.banq.qc.ca/patrimoine/details/52327/2243990?docsearchtext=ile%20de%20Montreal%201834

The next step in daylighting is called cultural restoration of the river.  Cultural restoration celebrates a buried river through markers, public art and activities to inform the public of its historic path and ecological role, and to raise awareness of the environmental issues and economic costs that have been created over time.

In the case of Montreal, the city has buried the St Pierre River and channelled it into its sewage system until only 200 metres of the original river remain above ground today – in the Meadowbrook golf course.  And those 200 metres are severely polluted through the continued crossing of sewage and floodwater pipes.  Members of Friends of Meadowbrook have begun the work of cultural restoration of the St Pierre River by organizing an annual bike ride along the river’s route from Meadowbrook to Pointe-à-Callière.

The ultimate goal of daylighting is natural restoration: to revitalize some or all of a river to recreate its original ecology and habitats and its rightful place as the centrepiece – the lungs and heart — of a community.
