Stormwater Drainage Prioritisation Under Budget and Equity Pressure
A municipal corporation has ₹18 crore for stormwater drainage in three flood-prone wards. Ward A has 45,000 residents, floods four times a year, needs ₹9 crore, and has narrow lanes where utility shifting is difficult. Ward B has 28,000 residents, floods once in three years, needs ₹4 crore, but its outfall drains into a lake requiring environmental clearance. Ward C has 60,000 residents, largely in SC/ST habitation, floods three times a year, needs ₹11 crore, and 30% of the drain alignment is under private land with pending acquisition. The standing committee wants work started in Ward A before the monsoon for visible impact. A state directive requires priority for vulnerable populations and cost-effective flood mitigation. A consultant proposes an additional retention pond in Ward B at ₹2 crore to reduce peak flow. The executive engineer must recommend a package within the budget and explain legal and administrative risks.
1. Recommend an allocation of the ₹18 crore among Wards A, B and C. State the criteria and trade-offs, and say whether the ₹2 crore retention pond should be funded now.

Use a documented prioritisation matrix: population exposed, flood frequency, vulnerability as per the state directive, cost per beneficiary, implementation readiness, and legal/environmental risk. Approximate exposure gives Ward C 60,000 × 3 = 180,000 flood-person-events per year and Ward A 45,000 × 4 = 180,000; Ward B is far lower at about 9,300. Cost per resident is Ward A ₹2,000, Ward B ₹1,429 and Ward C ₹1,833, but low cost per head in B does not offset its much lower risk.
A defensible recommendation is ₹11 crore for Ward C and ₹7 crore for Ward A, with Ward B and the retention pond deferred. Ward C scores highest on equity and exposure, but 30% land is not in possession; therefore release only the stretches where right of way is available and keep acquisition as a parallel milestone. Ward A gets a partial but high-frequency package, focusing on bottleneck reaches rather than spreading the money thinly. Funding all three would leave each incomplete and deliver little flood reduction.
The retention pond is technically attractive but should not be funded before lake clearance, hydrological verification and a cost-benefit check. Approving it now would consume contingency and create an unapproved outfall. Record the matrix, reasons for deferral and phased release conditions in the council note; this protects the decision against audit and political pressure.
2. What statutory and administrative steps are needed before work can begin in Ward C and Ward B? How would you avoid a project split that evades environmental clearance?
Read the worked answer
For Ward C, no physical work should start on private land without possession. Initiate acquisition under the RFCTLARR Act, 2013, including social impact assessment, preliminary notification, objections, award and payment; complete utility shifting and obtain right of way for each reach. If acquisition is delayed, tender only the available stretches and disclose the phasing so that the project does not become a stalled contract.
For Ward B, screen the drain outfall and retention pond against the EIA Notification, 2006, and any coastal or lake-protection rules. A drain discharging into a lake may require environmental clearance, consent to establish/operate and an environment management plan. Obtain revenue and irrigation department clearance for the outfall and verify that the pond does not encroach on the lake bed.
To avoid a split that evades clearance, define the project as one hydrological unit, check thresholds on the total catchment and capacity, and do not break it into sub-threshold tenders. Keep a screening note on file. Administratively, obtain council sanction, budget provision, technical sanction and a clear condition that work starts only after possession and clearances; otherwise the corporation risks stop-work orders and audit objection.
3. The standing committee insists on starting Ward A first. As executive engineer, identify the ethical and audit risks and the safeguards you would build into the note.
Read the worked answer
The main risks are political favouritism in allocating scarce funds, violation of the state directive on vulnerable populations, weaker value for money, and an audit para on bypassing objective prioritisation. There is also a public-trust risk: Ward C residents may see the decision as discriminatory if the highest-exposure, most vulnerable ward is deferred.
Safeguards: place the scoring matrix and weightages in the file; have the technical committee recommend the package in writing; record the reasons for the Ward A phase and the conditions for Ward C; obtain council approval rather than an executive fiat; disclose ward-wise allocations and timelines; provide a grievance register; and arrange third-party validation of flood-benefit estimates. If the committee overrules the technical recommendation, record the dissent and the directive in the note. Do not sign a note that states Ward A is technically the highest priority when the matrix shows otherwise. A short, transparent justification is better protection than a retrospective explanation after an audit query.
