Why pre-screen green infrastructure planners before the interview
These schemes fail slowly and without warning. Inlets silt up, planting is mown by a contractor who was never told what it was for, and within two summers the drainage performance has gone. Planners worth hiring arrange the maintenance regime and its funding before anything is built, and have gone back to look. A short screen asks what one of their schemes looks like now.
What actually matters when screening Green Infrastructure Planner candidates
- 01
Outcomes that landed
Ask which green infrastructure schemes reached construction: bioswales, rain gardens, tree canopy programmes, daylighted streams. Probe capital cost, catchment area treated, and post-build monitoring of runoff volumes.
- 02
Stakeholder facilitation
Probe how they handled resident objections at consultation events, negotiated maintenance agreements with highways or parks teams, and aligned developers, utilities and watershed groups on shared plans.
- 03
Regulatory and policy command
Test command of stormwater and planning instruments relevant here: NPDES MS4 permits, SuDS guidance, biodiversity net gain, local drainage standards, Section 106 or impact fee mechanisms.
- 04
Evidence and reporting
Look for GIS and modelling evidence: i-Tree Eco, SWMM or InfoDrainage runs, canopy and impervious surface analysis, and how findings shaped committee papers or capital programmes.
Pre-screening questions to ask Green Infrastructure Planner candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Schemes still working
3 questions01Can you describe your experience designing and delivering green infrastructure?
Listen forSchemes that were built with their own role stated, and knowledge of how each performs now.
Designs and strategies only, or no knowledge of whether a scheme was constructed as designed.
02Can you give examples of schemes using sustainable drainage?
Listen forSystems designed to a defined performance standard, with the design storm and treatment train described.
Drainage features described by appearance, or no hydraulic design behind the scheme.
03Can you describe a challenging project and how you addressed the difficulties?
Listen forA real constraint such as contaminated ground, buried services or adoption refusal, with the resolution.
Challenges described as stakeholder resistance, or no technical constraint they had to design around.
Performance measured
4 questions04How do you assess the environmental effects of your schemes?
Listen forBaseline established before works, with the assessment proportionate to the scale of the intervention.
Benefits asserted from the feature type, or no baseline taken before construction.
05How do you measure the performance of installed green infrastructure?
Listen forMonitoring of infiltration, vegetation establishment or temperature, with results compared to design intent.
Performance assumed from the design, or no monitoring after construction at all.
06Can you give examples of using native planting in your designs?
Listen forSpecies chosen for the actual conditions including waterlogging and salt, with establishment rates known.
Planting chosen from a standard list, or establishment failures not tracked.
07What is your experience with mapping tools in planning this work?
Listen forSpatial analysis used to target interventions where they will do most, rather than where space is available.
Locations chosen by land availability, or no analysis of where the need actually is.
Maintenance arranged
2 questions08What do you do to ensure schemes are maintained over the long term?
Listen forA maintenance regime agreed with a named responsible party and a funding source before construction.
Maintenance left to be arranged after handover, or the grounds contractor never briefed.
09Can you discuss your experience managing project budgets and timelines?
Listen forWhole-life cost considered including maintenance, with the ongoing cost presented to the client upfront.
Only capital cost presented, or maintenance cost discovered by the client after adoption.
Communities involved
3 questions10What role does public engagement play in these projects?
Listen forResidents involved before design is fixed, with a change made because of what they said.
Engagement described as informing residents, or no design change resulting from consultation.
11How do you approach integrating these features into existing urban areas?
Listen forExisting use and buried services surveyed early, with parking and access impacts addressed honestly.
Designs that ignore how the space is currently used, or services discovered during construction.
12How do you balance ecological benefits with economic and social considerations?
Listen forTrade-offs made explicit, with a case where an ecological ambition was reduced for a legitimate reason.
Trade-offs denied, or social concerns treated as obstacles to an environmental objective.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Outcomes that landed
30%5Names built schemes with acreage, litres of runoff managed, canopy percentage gained, and funding source secured for each.
Stakeholder facilitation
25%5Recounts a contested site where they reconciled highways, parks maintenance and residents into a signed, funded scheme.
Regulatory and policy command
25%5Cites the specific permit conditions and adoption standards they wrote against, plus how compliance was demonstrated to regulators.
Evidence and reporting
20%5Shows modelled versus monitored performance, explains variance honestly, and points to a decision the analysis changed.
Inlets silt up and the contractor mows the planting. A one-way video screen asks what their scheme looks like now.

Process basics
How long should a pre-screening round for this role take?
Fifteen minutes across eight to ten questions, answered async. Enough to establish schemes that were built, test their measurement practice, and check maintenance and engagement.
How much does local experience matter?
Considerably. Drainage standards, planning policy and adoption arrangements are all local, and someone arriving from another jurisdiction will need time before they can navigate approvals confidently.
Evaluating answers
What is the strongest signal when screening this role?
Going back to look at a completed scheme. Planners who follow their work describe what silted up or died. Anyone whose involvement ends at handover has never seen the failure modes.
How do I judge their maintenance thinking?
Ask who maintains a scheme and from which budget. Real answers name the responsible party and the funding. Anyone who has not resolved that has designed something that will stop working.
