Sketch Plan Submittal November 22, 2024 Limerick Village Page 3 of 3 Park areas are currently proposed near the center of the site and southwest corner of the site. The centrally located public park is 8 acres and positioned to equally serve all nearby residents while benefiting from the longer viewshed of the stormwater management features. The southwest park is approximately 1 acre and located in proximity to the apartments and single- family homes to provide additional recreation opportunities for the residents. UTILITIES The area is served with 12” watermain and a 24” sanitary sewer in Hudson Boulevard. Each stub is located within right-of-way and located approximately a quarter mile south of the southwest corner of the project site. It is the applicants understanding that each utility has capacity to serve the site and subject to routing to the site. It is the applicant’s intent to work with the abutting land owners to the south and west to determine an extension of the two utilities to the site and as part of the preliminary plat submittal. It is understood that the City of Lake Elmo is pursuing the construction of a water tower somewhere near the site to serve properties in this area. STORMWATER MANAGEMENT The property currently provides approximately 28,000 cubic feet of flood storage for the 100 year rainfall event, which floods to an elevation of 895.1 per VBWD hydraulic modeling. An additional 95,000 cubic feet of flood storage is provided on the property to the south at that same elevation. The sketch plan proposes to provide a local/regional stormwater management pond/infiltration basin of approximately 7.4 acres near the center of the site. It is currently proposed that the basin be outlet to the east under Manning Avenue to a ditch an approximate elevation of 890 which will provide for a basin normal water level of approximately 892 and an infiltration bench of approximately 890.7, which will provide approximately 40,400 cubic feet of flood storage or approximately 12,400 cubic feet of excess flood storage.
