J ,. I I I I I I -. I I I I I I I , I SUMMARY The City of Arden Hills includes a significant system of interconnected natural water bodies and a manmade drainage infrastructure system consisting of ditches, ponds, storm sewer piping and culverts, The field review of these systems indicated that very few significant problem areas exist within the City that need immediate attention, There was no indication of property (structure) damage occurring as a result of substandard drainage infrastructure in the City. Two nuisance problem areas were identified by residents living along McClung Drive and Siems Court and potential mitigation measures have been suggested and estimated for these two instances, The majority of items encountered in the survey are minor in nature and could be accomplished over time by City forces or grouped into bid packages to be let to contractors or added to larger public works contracts such as future street reconstruction programs, The City has budgeted $50,000,00 for drainage improvement work for the fiscal years 1999 and 2000 with an annual budget of$25,000,OO per year beginning in fiscal year 2001. Based upon our survey, the City Engineer feels that this budget will be adequate to address the problem areas identified in this report the next five years while providing for future repairs and maintenance which will be needed on the system, The funding may be better appropriated on a biannual basis for contracting purposes which would allow for greater economy of scale in assembling work packages to be let ($50,000,00 per biennium), The report also considered possible regional pond sites throughout the City, The intent of identifying the pond sites at this time is to include them as considerations when reconstructing streets and storm sewers in the future, Some pond sites are more independent than others relative to when they could be constructed, Some of the ponds shown are only possible to build by utilizing a portion of existing wetland areas or by acquiring private property, The Rice Creek Watershed District has allowed the construction of storm water ponds with some wetland impacts in the past under the philosophy that the water quality improvements realized through the storm water pond outweigh the wetland area "sacrificed", The Council should consider whether a portion of the City Storm Water Utility fund should be budgeted for potential future storm water regional pond construction, The City Engineer also recommends that the City collect additional water quality data in existing lakes and major wetlands and streams for prioritizing of water quality ponding improvements through the Water Quality Task Force, 11
