Environmental Petition

Save Cadogan Street Park from Needless Decontamination

552 Signatures Obtained, This Campaign Was Victorious!
Declared Victory: February 15, 2022

Target: 1000


Since 2015, in what was an amazing journey, the residents of Kennedy Town & Mount Davis collaboratively spoke up and fought the battle to save the only green grass park, the Cadogan Street Temporary Garden (CSTG) in our community. CSTG is maintained as a green park and has been serving the community for the past 22 years without the need for decontamination.  As we all think we can enjoy CSTG without disturbance, CEDD in January 2021 claimed that they insist on carrying out decontamination at CSTG, based on 21 years old out-dated soil data without proof of validity. The decontamination work will threaten the survival of the existing trees unnecessarily – and therefore such works must only be undertaken if absolutely necessary as proven by up to date soil sampling.

Join this petition to request CEDD to conduct proper soil testing to ascertain the need for decontamination.

Press article: CEDD insists decontamination is needed, backed with 20 year old data. Experts said the park is safe for use

Soil testing results showed Cadogan Street Temporary Park is safe for use and does not need to be decontaminated. “The quality (soil) is as good as the soil used in organic farming”, said Professor CHIU.

Online Press Conference

Petition organisers and Professor CHIU Siu Wai briefed the media and the public on Friday, 28th May 2021, about the soil testing result, evidence of removing Cadogan Street Temporary Garden (CTSG) from the decontamination area, and areas for improvement in the decontamination project and current Environmental Impact Assessment system. They urge the government to make decisions based on scientific data and retain the whole CTSG for public use during the decontamination work in the adjacent lands.

Test report said the soil is up to standard

Professor CHIU Siu Wai, an expert in decontamination, released the soil testing report. The results showed the levels of heavy metal arsenic and lead, and organic matter Benzo[a]pyrene are within the chemical limit of Risk-Based Remediation Goals (RBRGs), indicating that the park is safe for use and decontamination is not needed. Soil samples were collected and sent to a testing laboratory under Hong Kong Laboratory Accreditation Scheme in early March.

Petition Letter

To Secretary for Development, Director of Civil Engineering and Development, Central and Western District Council,

We strongly request Civil Engineering and Development Department (CEDD) to conduct a soil testing at Cadogan Street Temporary Garden (CSTG) to ascertain the need for the proposed decontamination due to the following reasons.

Decision that CSTG still needs decontamination is based on very outdated data without proof of validity

Recently CEDD has proposed to include CSTG in the scope of the Kennedy Town decontamination project, covering the site of the former incineration plant and abattoir, and their adjoining areas. Based on the data of contaminants collected in 2000, with 21 years of history, CEDD claims CSTG has to be decontaminated. It is not acceptable that CEDD justifies the need for decontamination work with out-dated data. The concentration and composition of contaminants in soil should have changed over time as a result of different natural chemical processes including phytoremediation, half-life of the contaminants, and natural wash-off by rainwater [1]. In spite of the soil contamination, the trees and other plants in CSTG are thriving. CEDD and Environmental Protection Department also told the residents that CSTG is safe to use as a park for the past 22 years. The decontamination project is avoidable if the soil is found to contain a low, harmless level of contaminants. Thus a soil testing is necessary to assess the need for the decontamination project.

Avoidance to cause unnecessary damages to CSTG and its trees   

CEDD claimed that they have considered preserving the trees at CSTG despite their decontamination work [2].  However, if CEDD cannot guarantee the soil under the area of tree canopy (tree dripline) and the root distribution network are excluded from decontamination to ensure no damage to the existing trees above- and under-ground, decontamination work can unnecessarily cause irreversible physical damage to the tree root network, threatening the survival of the existing trees unnecessarily.  It is worrying that the trees in CSTG may not survive through the operation, damaging the landscape of CSTG.

Avoidance of disturbance to residents

CSTG has been serving the community in Kennedy Town for 22 years. To many residents of Kennedy Town, it is an inseparable part of the community, not to mention it is the only quality, convenient, and well-located green park in Kennedy Town. In 2015, the outline zoning plan of Kennedy Town & Mount Davis proposed to demolish CSTG for developing private residential buildings [3]. Over 5000 representations were submitted to the Town Planning Board (TPB) by the concerned residents to request the retention of CSTG. Due to the lack of public open space in Kennedy Town and the importance of CSTG to the local community, TPB acknowledged the importance of CSTG and thus decided to retain the park as Open Space for public park use. If CEDD goes ahead with this decontamination, residents’ access and use of this important green space will be interrupted unnecessarily, while causing potential health hazard to residents due to potential complications arising during decontamination.

The local community is very concerned about the negative impacts of the decontamination project on CSTG due to the aforementioned reasons. We hereby reiterate that the decontamination based on out-dated data is a mal-administration and should not take place. We strongly request CEDD to conduct a soil testing to ascertain the need for decontamination work at CSTG, with the aims of avoiding damages to CSTG and its trees, disruption of use/access to CSTG by the residents, causing potential health hazard to residents, and the misuse of public money. The decontamination project at CSTG should be withdrawn if the recent level of contaminants does not exceed the threshold for decontamination as a public park.
