Project Overview

The second-floor terrace of the Times Shangcheng North Community Party-Mass Service Center in Jinji Lake Subdistrict, Suzhou Industrial Park, serves as the main passage for residents to the community activity room. Current Problem: With the increasing frequency of extreme rainfall events, the existing drainage system has become overwhelmed, creating a vicious cycle of “flooding when it rains heavily, and closure when backflow occurs.” Residents have reported that “coming home used to mean just sleeping; community life felt a bit mechanical.” The combination of idle space and social detachment among neighbors has become a persistent challenge for community governance.

Root Cause Analysis: This terrace represents a typical case of aging infrastructure in existing urban spaces—the drainage pipelines are deteriorated and outdated, with low design standards. Against the backdrop of climate change-induced increases in extreme rainfall, the carrying capacity of the original facilities is severely inadequate. Meanwhile, the long-term idleness of the space has been compounded by a lack of effective community participation and co-governance mechanisms. Improvement Goals: Guided by the “sponge city” development concept, and through Party-building-led multi-stakeholder collaboration, this “flooding pain point” is to be transformed into a community “ecological living room” integrating rainwater storage, ecological display, neighborhood interaction, and nature education—exploring a low-cost, climate-adaptive micro-renewal pathway for existing urban spaces.

项目背景

苏州工业园区金鸡湖街道时代上城北社区党群服务中心二楼露台，是居民前往社区活动室的必经通道。

问题现状：随着极端降雨天气频次增加，原有排水系统不堪重负，形成“下大雨就积水、雨水倒灌就停用”的恶性循环。居民反馈“以前回家就是睡觉，社区生活有点‘机械’”，空间闲置与邻里疏离相互叠加，成为社区治理的“心病”。

原因分析：该露台为典型的城市存量空间设施老化问题——排水管网年久失修，设计标准偏低；在气候变化导致极端降雨增多的背景下，原有设施的承载能力严重不足；同时，空间长期闲置，缺乏有效的社区参与和共治机制。

改进目标：在“海绵城市”建设理念指引下，通过党建引领下的多方共建，将这一“积水痛点”改造为集雨水调蓄、生态展示、邻里交往、自然教育于一体的社区“生态客厅”，探索低成本的存量空间气候适应型微更新路径。

 

Project Implementation

Targeting the climate adaptation pain point of waterlogging in community public spaces, the project adopted an implementation approach of “Party-building leadership, multi-party coordination, ecological renovation, and public participation.” After six months of collaborative efforts, it was fully completed and put into operation in June 2026.

(I) Party-Building Leadership: Establishing a Six-Party Co-Building Mechanism

In November 2025, led by the community Party organization, six parties—Wendao Network, BenQ Youda Foundation, SIP Municipal Services Group, Mufeng Environmental Protection, Times Shangcheng North Community, and Shangcheng Kindergarten—formally signed a co-building agreement for the “Wendao Rain Garden” project.

Division of responsibilities and coordination among all parties: Wendao Network: Provided corporate ESG public welfare funding to secure the project’s financial foundation;

BenQ Youda Foundation: Oversaw fund management and ensured process transparency throughout the project;

SIP Municipal Services Group: Provided professional technical guidance to ensure the scientific feasibility of the plan;

Mufeng Environmental Protection: Coordinated the full-process planning, design, and construction implementation;

Times Shangcheng North Community: Conducted in-depth resident mobilization and coordination to solidify the foundation for implementation;

Shangcheng Kindergarten: Utilized the garden as an outdoor learning base to disseminate knowledge on climate change and the water cycle starting from early childhood.

(II) Ecological Renovation: Addressing Stormwater Issues through Nature-Based Solutions

The project abandoned the “large-scale demolition and construction” model and focused on pragmatic, ecological renovation goals:

Addressing waterlogging: The community led a comprehensive review and reorganization of the existing aging drainage pipelines, optimizing drainage and diversion design to fundamentally solve the terrace’s rainwater accumulation and backflow problems.

Addressing rainwater resource waste: A rainwater collection, sedimentation, and utilization system was established to capture and filter natural rainfall for routine irrigation of landscape plants, achieving rainwater recycling. The garden features six functional zones: rainwater collection and storage system, rainwater-purifying micro-wetland, vertical greening wall, succulent planting area, herb planting area, and composting area—comprehensively delivering three core functions: stormwater management, environmental beautification, and resource recycling.

Addressing construction waste: Embracing the concept of material circularity, the open-air wooden trellises dismantled during construction were re-cut and reassembled into garden compost bins for storing fallen branches and leaves to be fermented into organic fertilizer on-site—reducing construction waste generation while achieving closed-loop resource utilization.

(III) Public Participation: Cultivating Community Co-Governance Capacity

The project simultaneously launched the “Garden Co-Builder” recruitment program, guiding residents to transform from “spectators” into “builders” and “maintainers.” In January 2026, resident volunteers, design experts, and staff jointly participated in site clearing, rainwater system reconstruction, and terrain shaping. After the garden was fully completed in June 2026, community residents and kindergarten teachers and students were organized to participate in flower border planting and planter micro-renovations—with elders planting seedlings, children tending soil, and youth managing maintenance—building community ecological consensus through collective construction.

项目实施

针对社区公共空间积水内涝这一气候适应痛点，项目采取“党建引领、多方协同、生态改造、全民参与”的实施路径，历经半年协同推进，于2026年6月全面建成投用。

（一）党建引领，构建六方共建机制

2025年11月，在社区党组织牵头下，闻道网络、明基友达公益基金会、园区市政服务集团、沐风环保、时代上城北社区、尚城幼儿园六方党组织正式签约共建“闻道雨水花园”项目。

各方分工协同：

闻道网络：以企业ESG公益出资，筑牢项目资金底盘；

明基友达公益基金会：全程规范资金管理与流程透明；

园区市政服务集团：输出专业技术指导，确保方案科学可行；

沐风环保：统筹全流程规划设计、施工落地；

时代上城北社区：深耕居民动员协调，夯实落地根基；

尚城幼儿园：将花园作为户外研学基地，从孩童阶段普及气候变化与水循环知识。

（二）生态改造，以自然手法解决雨洪问题

项目实施摒弃“大拆大建”模式，聚焦实用化、生态化改造目标：

针对积水内涝问题——对原有老旧排水管路进行全面梳理和重新规整，优化排水导流设计，从源头解决露台雨天积水、大雨雨水倒灌问题。

针对雨水资源浪费问题——搭建雨水收集、沉淀、利用体系，将自然降雨统一收纳过滤，用于常态化浇灌景观绿植，实现雨水资源循环利用。花园落地六大功能分区：雨水收集调蓄系统、雨水净化小微湿地、立体绿化墙面、沙生植物种植区、香草种植区、堆肥区，全维度实现雨洪管控、环境美化、资源循环三大功能。

针对建筑废弃物问题——践行旧物循环理念，施工中拆除的露天木质花架，经过重新切割、组装，变身为花园堆肥箱，用来存放枯枝落叶就地发酵有机肥，既减少了建筑垃圾产生，又实现了资源闭环利用。

（三）全民参与，培育社区共治力量

项目同步启动“花园共建官”招募，引导居民从“旁观者”转为“建设者”和“维护者”。2026年1月，居民志愿者、设计专家、工作人员共同参与场地清障、雨水系统重塑、地形塑造等施工环节；2026年6月花园全面建成后，又组织社区居民、幼儿园师生参与花境种植与花坛微改造，老人栽苗、孩童培土、青年运维，在共同营建中建立社区生态共识。

 

Project Outcome

Spatial Transformation: The once “flooded wasteland” has been transformed into a “breathing, water-absorbing, living” community ecological infrastructure integrating rainwater storage, vertical greening, and nature education. The rainwater collection and storage system captures rooftop and pavement runoff on-site, while the ecological micro-wetland filters and purifies rainwater, significantly reducing peak runoff and addressing community flooding risks from extreme rainstorms. The vertical greening wall, combined with multi-layered vegetation, creates a micro-ecological cooling island that effectively mitigates localized heat island effects in the residential area.

Governance Innovation: A six-party co-building model featuring “Party-building leadership, corporate funding, foundation oversight, SOE empowerment, social organization implementation, and community + campus coordination” has been pioneered. This model establishes a complete chain from “addressing climate-induced waterlogging pain points—building resilient ecological spaces—cultivating public low-carbon water conservation action.” Suzhou Daily commented that it “skillfully solves community governance challenges with the ‘golden key’ of Party-building.”

Community Activation: The “Garden Co-Builder” mechanism has transformed residents from “spectators” into “stewardship actors.” This small garden has revitalized neighborhood interactions, reconnecting previously isolated community members through collective construction. Resident feedback: “Seeing everyone busy working for the same garden has warmed up our neighborhood relations—it feels like the community’s happiness has increased!”

Replicability: The project replaces traditional engineering renovation with low-cost, nature-based ecological approaches. The six-party co-building model is well-suited to the micro-renewal needs of existing spaces in Suzhou’s water town context, providing a scalable and replicable practical template for climate-adaptive renovation of similar communities.
