The City of Omaha Public Works Department Compost Facility project (Project) is located landward of the NEDOUG16 Left Bank and Little Papio Left Bank Levee system (Levee), north of Harrison Street in Douglas County, Nebraska. A portion of the project site is located within the Critical Area of the Levee. The critical area as defined by the United States Army Corps of Engineers (USACE) extends from 300 feet riverward to 500 feet landward of the levee centerline. An overall site plan is provided as Figure 1. This figure includes a site location map inset. The Project consists of the construction of a yard waste and septage processing facility for the City of Omaha. Site improvements include the construction of a pre-engineered building, vehicle scales, a concrete paved access drive and parking lot, aggregate surfacing, a septage receiving pit, and utilities including a reinforced concrete stormwater detention basin. The existing baseball complex will be removed including removal of all above-ground structures and removal of below-ground water, sanitary, storm, and electrical utilities. The water and sanitary lines will be capped at the main. An approximately 10-foot-long section of storm sewer will be plugged and abandoned in place beyond the removed sections of storm sewer. The Papio-Missouri River Natural Resources District (P-MRNRD) operates and maintains the Levee, which consists of an earthen embankment that provides flood risk reduction along the left (east) bank of the Little and Big Papillion Creeks from L Street to the mouth of Copper Creek. The Levee begins along the Little Papillion Creek at L Street where it ties into the roadway approach embankment. The Levee is combined with the Keystone Trail pedestrian embankment from L Street to approximately 15,000 feet downstream. The Levee parallels the Big Papillion Creek until it turns east at Copper Creek. The Levee is not federally constructed and does not have an Operation and Maintenance (O&M) Manual. The proposed compost facility will include: o OMA-GRO Building (pre-engineered metal building approximately 6,000 square feet). o Scale. o Stormwater Basin (including clay liner and 8-inch-thick concrete pad) with cast-inplace retaining walls (up to 7 feet wall height). o Septage Receiving (5 feet deep pit surrounded by a 12-inch-thick concrete pad) with cast-in-place retaining walls (up to 2.5 feet wall height). o Access drive consisting of 7 to 9 inches of concrete paving. o Rock surfacing for non-structural/non-paving areas (14-inch-thick) New site utilities will include: o Sanitary sewer lines (6-inch and 8-inch diameter) with invert elevations ranging from approximately Elevation 986.9 to 1004.2 feet. o Sanitary sewer manholes (SS-MH-1 through SS-MH-5) with invert elevations for the sanitary sewer manholes ranging from approximately Elevation 988 to 1003 feet. o Storm sewer lines (12-inch and 24-inch diameter) with invert elevations ranging from approximately Elevation 987 to 991.5 feet. o Storm sewer manholes (SD-MH-1 through SD-MH-4 and SD-C1-1) with invert elevations ranging from approximately Elevation 987.5 to 998.5 feet. o Electrical and fiber optic lines installed at depths of 5 feet below grade including handholes and manholes. o Gas lines installed at depths of 5 feet below grade. o Water lines (2-inch, 3-inch, 6-inch, and 8-inch diameter) installed at a depth of 5 feet below grade. o Light poles, camera poles, and other electrical structures supported on drilled concrete piers. Existing site grades within the proposed development area on the north side of the Blood Creek range from Elevation 1,000 to 1,011 feet. Grading will be completed in the area to establish site grades between Elevation 997 and 1,012 feet. Proposed cut and fill thickness at each structure location are provided below: o OMA-GRO Building - 5 to 6 feet of fill. o Scale - 1 to 2.5 feet of fill. o Stormwater Basin - 8 feet of cut to 3 feet of fill. o Septage Receiving Pit - 1 to 3 feet of cut. Proposed grading at access drive will require up to 3 feet of cut and 4 feet of fill. An existing baseball complex will be removed including removal of all above-ground structures and removal of below-ground water, sanitary, storm, and electrical utilities. The water and sanitary lines will be capped at the main. An approximately 10-foot-long section of storm sewer will be plugged and abandoned in place beyond the removed sections of storm sewer. The proposed Omaha Compost Facility consists of the following improvements: o Pre-engineered Metal Building (OMA-GRO) (approx. 6000 sq.ft) and Scale Sales o Stormwater Basin (12-inch thick concrete basin) o Septage Receiving Pit (5 foot deep concrete pit surrounded by a 12-inch thick concrete pad) o 14 inches of rock surfacing for non-structural/non-paving areas A overall site plan is provided as Figure 1 and boring locations are provided as Figure 2. Plans and specifications for the proposed Omaha Compost Facility are provided in the appendices of the technical review submittal. The existing baseball complex will be removed including removal of all above-ground structures and removal of below-ground water, sanitary, storm, and electrical utilities. The water and sanitary lines will be capped at the main. An approximately 10-foot-long section of storm sewer will be plugged and abandoned in place beyond the removed sections of storm sewer. The pre-engineered metal building will be supported on shallow spread footings. The light poles will be embedded into 3-foot diameter drilled concrete piers. Electrical, fiber optic, gas, storm sewer (12-inch and 24-inch), and sanitary sewer (6-inch and 8-inch) utilities will be installed at depths of 5 to 13 feet below grade. Water lines (2-inch, 3-inch, 6-inch, and 8-inch) will be installed at a depth of 5 feet below grade. The proposed access drive will have 7 to 9 inches of concrete paving over a compacted subgrade. Remaining portions of the non-structural areas on site will be surfaced with 14 inches thickness of crushed rock. Existing site grades within the proposed development area on the north side of the blood creek range from Elevation 1,000 to 1,011 feet. Grading will be completed in the area to establish site grades between Elevation 997 and 1,012 feet. Proposed cut and fill thickness at each structure location are provided below: . o Pre-engineered Metal Building (OMA-GRO) and Scale Sales - Minimal cut and about 6 feet of fill. o Stormwater Basin - About 8 feet of cut and minimal fill. o Septage Receiving Pit - About 3 feet of cut and fill. A grading plan and site Plan with cross-sections (CS-1, CS-4, CS-5, Scour Hole/Plunge Pool) is provided as Figure 3. It is assumed that grading along the access drive will require less than 1 foot of cut or fill. The sanitary sewer lines (6-inch and 8-inch) and the storm sewer lines (12-inch and 24-inch) are proposed. Some portions of the sanitary and storm sewer lines are in within the levee critical zone. The invert elevations for the sanitary sewer lines will range from approximately Elevation 980.4 to 1004.20 feet. The invert elevations for the storm sewer lines will range from approximately Elevation 987 to 991.5 feet. The sanitary sewer manholes (SS-MH-1 through SS-MH-5) and the storm sewer manholes (SD-MH-1 through SD-MH-4 and SD-C1-1) are proposed. Some of the sanitary and storm sewer manholes are within the levee critical zone. The invert elevations for the sanitary sewer manholes will range from approximately Elevation 988 to 1003 feet. The invert elevations for the storm sewer manholes will range from approximately Elevation 987.5 to 998.5 feet.
