Genangan di Kelurahan Bulak, Kecamatan Kenjeran, Kota Surabaya bukan disebabkan meluapnya sungai, namun lebih dikarenakan tingginya intensitas hujan lokal yang diperparah dengan buruknya manajemen drainase kota, disamping itu kontur wilayah Kelurahan Bulak merupakan permukaan yang relatif datar dengan jenis tanah yang mempunyai resapan rendah. Upaya yang telah dilakukan oleh Pemerintah Kota Surabaya dalam mengantisipasi genangan yakni membangun rumah-rumah pompa banjir, membuat gorong-gorong, biopori, membersihkan saluran dari timbunan sampah, dan melakukan pengerukan sedimen di bozem yang merupakan tempat penampungan air hujan sementara sebelum dibuang ke laut. Namun saat ini semua upaya tersebut belum cukup membuahkan hasil dalam menangani genangan air. Salah satu cara yang efektif untuk menangani genangan air adalah memodifikasi lapisan tanah permukaan dengan menambahkan pupuk kompos dedaunan dan ranting. Penelitian ini untuk menentukan pengaruh jumlah kompos yang ditambahkan pada tanah terhadap peningkatan resapan dan reduksi lama genangan banjir. Penelitian dilakukan menggunakan metode pencampuran tanah dan kompos pada skala laboratorium. Penelitian ini menggunakan variabel penelitian jumlah kompos yang ditambahkan. Parameter yang dianalisis adalah jenis tanah dan laju resapan tanah (f). Hasil penelitian menunjukkan penambahan kompos daun dan ranting sebesar 15% ke tanah dapat meningkatkan resapan dari 0,298 cm/menit menjadi 0,904 cm/menit dan penambahan kompos daun dan ranting 35% dapat meningkatkan resapan menjadi 1,099 cm/menit
