A side slope 3:1 (horizontal to vertical) is configured, which results in 92.04 ft long and 57 ft wide at the height of 2 ft.\n\n[OCR image]\nExample 1 - Geometry\nStep 4: Estimated Drain Time Calculation\n\nAs previously stated, the drain time of the basin is determined by the design permeability rate of the subsoil. Note that only the infiltration area, i.e. the footprint, can be credited for infiltration, meaning infiltration may not be applied to the side slopes. The drain time calculation is based on the area of the footprint, which is 3,6", "asset_id": "2026_BMP_10_2__image__0014__01__b6dae686", "document_id": "2026_BMP_10_2", "path": "BMP/2026/10.02 - Infiltration Basins (Large-Scale GI)/images/page-0014-img-01.jpg", "association": "exact_source_pdf_and_page", "record_ids": [ "2026_BMP_10_2__0014__001", "2026_BMP_10_2__0014__002" ], "direct_record_ids": [ "2026_BMP_10_2__0014__001", "2026_BMP_10_2__0014__002" ], "table_record_ids": [], "display_asset_id": "2026_BMP_10_2__image__0014__01__b6dae686" }, { "source_pdf": "BMP_2026/2026_BMP_10_2_Infiltration_Basins.pdf", "source_pdf_sha256": "999f8d85f63b9a1c7f8ea127c9537c06f81bef9f42627bde3b720cef8fc93fce", "source_manifest": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/manifest.json", "source_manifest_sha256": "132592a7f4cecd5dcfd4bafc458036ebcf4fae2fc28e79a1a162b20a4ce36175", "source_response": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/response.json", "source_response_sha256": "2a7ab06f204015ce91a31f5967b5aa5463c49b9a0e01455fc829b54f788b0158", "source_image": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/pages/page-0015-img-01.jpg", "sha256": "eb251bb0185b023eaa010fdd454ad99280a8f6a42c57045b1775d544fa8a2bd1", "bytes": 56093, "pdf_page": 15, "ordinal": 1, "ocr_image_id": "img-13.jpeg", "local_path": "images/page-0015-img-01.jpg", "bbox_pixels": [ 297, 237, 1305, 770 ], "page_dimensions": { "dpi": 200, "height": 2200, "width": 1700 }, "ocr_provider": "mistral", "ocr_model": "mistral-ocr-latest", "context_excerpt": "[OCR image]\nExample 1 - Plan View\n\n[OCR image]\nExample 1 - Profile and Cross-Section View", "asset_id": "2026_BMP_10_2__image__0015__01__67ffee88", "document_id": "2026_BMP_10_2", "path": "BMP/2026/10.02 - Infiltration Basins (Large-Scale GI)/images/page-0015-img-01.jpg", "association": "exact_source_pdf_and_page", "record_ids": [ "2026_BMP_10_2__0015__001" ], "direct_record_ids": [ "2026_BMP_10_2__0015__001" ], "table_record_ids": [], "display_asset_id": "2026_BMP_10_2__image__0015__01__67ffee88" }, { "source_pdf": "BMP_2026/2026_BMP_10_2_Infiltration_Basins.pdf", "source_pdf_sha256": "999f8d85f63b9a1c7f8ea127c9537c06f81bef9f42627bde3b720cef8fc93fce", "source_manifest": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/manifest.json", "source_manifest_sha256": "132592a7f4cecd5dcfd4bafc458036ebcf4fae2fc28e79a1a162b20a4ce36175", "source_response": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/response.json", "source_response_sha256": "2a7ab06f204015ce91a31f5967b5aa5463c49b9a0e01455fc829b54f788b0158", "source_image": "BMP_2026/raw/2026_BMP_10_2_Infiltration_Basins/pages/page-0015-img-02.jpg", "sha256": "4a044b596389ba767877d8c05ef4e565e4c24d2ac92cd0b4c276f40a9fc3956f", "bytes": 91762, "pdf_page": 15, "ordinal": 2, "ocr_image_id": "img-14.jpeg", "local_path": "images/page-0015-img-02.jpg", "bbox_pixels": [ 297, 844, 1300, 1863 ], "page_dimensions": { "dpi": 200, "height": 2200, "width": 1700 }, "ocr_provider": "mistral", "ocr_model": "mistral-ocr-latest", "context_excerpt": "[OCR image]\nExample 1 - Plan View\n\n[OCR image]\nExample 1 - Profile and Cross-Section View", "asset_id": "2026_BMP_10_2__image__0015__02__a7262db1", "document_id": "2026_BMP_10_2", "path": "BMP/2026/10.02 - Infiltration Basins (Large-Scale GI)/images/page-0015-img-02.jpg", "association": "exact_source_pdf_and_page", "record_ids": [ "2026_BMP_10_2__0015__001" ], "direct_record_ids": [ "2026_BMP_10_2__0015__001" ], "table_record_ids": [], "display_asset_id": "2026_BMP_10_2__image__0015__02__a7262db1" } ] }
