4 MUNICIPAL SERVICES CENTER MASTER PLANINTRODUCTION AND PROJECT GOALS


Introduction and Project Goals


Introduction and Project Goals The City of Des Moines currently operates its field services from several older and outdated facilities scattered around the city. These services include the Departments of Public Works and Parks and Recreation, plus other services such as Engineering, Fleet, Traffic and Transportation, Housing Services maintenance, satellite maintenance facilities, and other service uses. In order to develop interdepartmental teams and cooperation, and to realize all potential organizational efficiencies, these services need to be consolidated and centrally located in a single campus location.

Currently these facilities are housed in older buildings, many of which were converted years ago for use by the city field services departments. While these buildings are serving the needs of these departments, they are far less than ideal in providing adequate, efficient working environments. In addition, the facilities located at SE 20th and Scott need to be relocated to allow for the future extension of the SE Connector; the timing of this relocation is driven by Kemin Industries planned expansion into areas that will be excess site after completion of the SE Connector. The area around the facilities at SE 5th and Market Streets is beginning to experience interest in redevelopment due to the recent Martin Luther King Jr. Bridge construction and extension of the SE Connector. This facility will eventually need to be relocated to allow for development of the planned Market District.

The purpose of this Master Plan is to guide this endeavor towards achieving the following goals:

Create a cohesive vision and plan for the development of a City of Des Moines Municipal Services Center that: can be phased and implemented over a period of many years includes a realistic long-term facilities and space needs program improves efficiency in delivering City services taking into account the needs

resulting from population growth in the City, including annexed areas Create a detailed estimate of probable cost for each phase of development Improve worker safety; incorporate industry standards and best practices for

service facilities Revitalize the SE 14th Street Corridor Create a facility that adheres to sustainable principals and best environmental

practices with regards to site planning and facility design. Sustainable features should recognize the City as a long-term owner and include those features which contribute to long-term economic efficiencies without overburdening initial capital costs

Consolidate services in Des Moines to deliver services more efficiently and effectively (potentially in collaboration with entities in addition to the City, such as the State, Des Moines Public Schools, Polk County, and/or local utilities)

Accommodate and encourage economic development in the City of Des Moines that positively contributes to the quality of life in the city and to the tax base

36 MUNICIPAL SERVICES CENTER MASTER PLANMASTER PLAN DEVELOPMENT PROCESS


Master Plan Development ProcessSummary

Public Meetings


Master Plan Development Process

The planning team spent many hours over a four month period meeting with city staff from the Public Works, Parks and Recreation, Fleet Traffic Engineering and Housing Divisions assessing needs, inspecting facilities, inventorying equipment, and analyzing operations. The planning team and city staff also met with representatives from the State of Iowa, Polk County, The Des Moines Public Schools, Des Moines Area Regional Transit (DART), Des Moines Water Works, and Mid American Energy to introduce the concept of co-locating public services.

The following committees were assembled to assist and guide the planning efforts: Technical Committee: made up from representatives from the City Managers

Office, Engineering, Public Works, Parks and Recreation, and Community Development Departments

Advisory committee: made up of key staff at other public entities and institutions, including Polk County, State of Iowa, DART, Des Moines Public Schools, and MidAmerican Energy

City Council: through a Council Workshop, briefings, and City Council meetings Public: through an open house

The planning team also worked with a geotechnical engineering firm contracted by the City to determine the boundary and development opportunities/limitations of the existing Harriet Street Landfill and the Iowa Flood Center to assess potential flooding conditions for the study area.

As information was assembled and analyzed the planning team regularly reviewed this data with the city Project Manager and Committee to verify the information was correct and to discuss various development options. Every individual, department, and service affected by this plan was accounted for as well as every major piece of equipment, including service vehicles.

Several potential development sites within the study area were investigated to determine the best location for the Municipal Services Center. These options took into account accessibility for service vehicles, the public, and city employees, the potential to stimulate adjacent private redevelopment, physical site conditions, current and future street improvements and extensions, storm water management, land acquisition requirement, development costs, and opportunities for phasing development of the Municipal Services Center.


Public Meetings

To solicit further input, the City staff and the planning team also presented their cursory findings and recommendations to:

1. The Des Moines City Council at a public workshop on July 11, 2011. 2. Public Open Houses on July 20, 2011.3. A joint meeting with the Urban Design Review Committee, the Parks and Recreation

Board, the Plan and Zoning Commission, and the Neighborhood Revitalization Board on July 21, 2011.

The presentations given at the City Council Workshop and to the public and Boards and Commissions were very similar. The presentations highlighted the immediate need to relocate various facilities due to the extension of the SE Connector and the expansion of Kemin Industries. The long-term operational benefits of reducing costs and improving service delivery were presented as objectives of the Municipal Services Center Master Plan. The plan for phasing the implementation of the Municipal Services Center and the possible opportunities for redevelopment in the area were explained. Both city staff and the planning team were present to address questions at all meetings.

Overall, attendees at all meetings found the project favorable; no objections to the project were expressed. The urgency to move efficiently through the project to implementation of the phase 1 facility was conveyed. There seemed to be sentiment among all groups that implementing the second phase of the project would be of benefit to the City.

City Council Workshop

On July 11, 2011 at 7:30am, the City Council was presented with the preliminary findings and recommendations for the Municipal Services Center. Content of the presentation included background on the needs and precedents for the facility, an overview of the site area, recommendations for phasing the facility, opportunities for redevelopment of the area surrounding the recommended site, and costs associated with implementing the first phase of the facility.

Questions from this workshop include the following:

Council members inquired about the process for acquiring the site for Phase 1.


The staff indicated that the carefully-regulated official process for communicating with the property owner about the Citys interest in acquiring land in the area had begun.

Council members inquired about the interim costs incurred, or that will be incurred, in the process of phasing in the MSC. The staff is tracking all interim costs associated with the project, including those expenses such as temporary moves incurred in the interim of constructing the MSC facility as a part of the overall budget for the MSC.

Council members expressed enthusiasm for the accomplishment of multiple city initiatives with the MSC master plan including the potential for revitalizing the MSC project area, facilitating economic development for an established and promising Des Moines business (Kemin Industries), and facilitating redevelopment of the Market District.

Council members asked for ideas that would accelerate the implementation schedule of the project, especially Phase 2, to ensure the best opportunities for the Market District and realize the advantages of the full MSC facility sooner.

Council members requested that additional relocation of industrial uses in the Market District be considered as the MSC master plan is finalized.

Public Open Houses

At the July 20, 2011 public meetings, two presentations were given by the Community Development Director, Phil Delafield. Approximately 40-45 participants attended the 3 PM session while the 6 PM presentation had 8-10 attendees. This included business and property owners in the SE 14th St. and Market District areas, neighborhood residents, neighborhood leaders, and potential developers. Various City staff and the planning team were on hand to field questions and provide further clarification on the presentation

Following each presentation the attendees were given an opportunity to ask questions, voice concerns, and offer input. The questions at the public meetings included:

How much land is needed to construct the facility? 42-45 acres; approximately 11.5acres of this is needed for Phase 1

Will eminent domain be utilized to acquire property? Potentially. How much money is budgeted for land acquisition? $2 million is budgeted for

purchasing and, if needed, relocating property owners for Phase 1.


What is the timing for Phase 1 and Phase 2? The City is planning to work on land acquisition and site preparation for Phase 1 through 2012, construct Phase 1 in 2013, and occupy the first phase of the Municipal Services Facility in mid-2014. Timing for Phase 2 has not yet been determined.

Will Scott Avenue be closed? Scott Avenue will not be closed for Phase 1. Phase 2 will close Scott Avenue between SE 15th Street and SE 18th St., however, to preserve efficient traffic circulation in the area, the City feels that it will not be possible to close this section of Scott Avenue until the SE Connector has been constructed to SE 18th St. The SE Connector will be complete to SE 15th St. in 2013 and design work is underway for the next segment of the roadway, however funding is not yet in place to construct the next section of SE Connector. The City anticipates that construction on the section east of SE 15th Street in 2-4+ years.

How does this plan relate to plan for re-constructing and widening SE 14th Street? A number of configurations of the future alignment of SE 14th Street have been studied and the plan shown would allow for either a wide (SE 14th-15th 1-way pair) or narrow roadway configuration. The planning team believes that a narrow configuration would be of greater benefit to the long-term redevelopment of the area. SE 14th St. is a State Highway; the State DOT will need to be involved in making design decisions about the roadway configuration and there is not currently funding in place from the State to reconstruct SE 14th Street and design work is not currently underway, so timing of this project is unknown.

WhyisnttheHarrietLandfillbeingusedforthisproject?It is not possible to construct buildings on top of this landfill. There is not adequate buildable area on the sites immediately surrounding the landfill to construct the scale of facility needed to house the long-range needs for the Citys municipal services.

Are there plans to clean-up the abandoned recycling center at SE 14th St. & Scott Ave.? Residents expressed health concerns with the current condition on this site. The MSC facilities do not include this site. The Master Plan for the area shows redevelopment on this parcel, but there are challenges with current bankruptcy actions and environmental clean-up requirements. The City has not currently directed resources towards cleaning up this site.

The property owner of land in the Phase 1 area was represented at both meetings and inquired about funds available for acquisition and timing of implementation and were given the aforementioned answers to their questions. Several property owners in the Phase 2 and redevelopment areas inquired about the status of their property. These property owners were told that currently the City is not actively pursuing acquisition


in these areas and that funds have not been allocated for purchases in this area, but that purchase of property in the areas shown for the Phase 2 facility may be considered in the coming months.

Participants were encouraged to visit the Citys website for the MSC (http://www.dmgov. org/Departments/CommunityDevelopment/Pages/MunicipalServiceCenter.aspx) for future information

Joint Boards and Commissions Meeting

Approximately 35 people from the Plan and Zoning Commission, Urban Design Review Board, Neighborhood Revitalization Board, and Park and Recreation Board attended the Boards and Commissions joint session on July 21 at 5:30pm.

Questions and comments from the Boards and Commissions session included:

What is the value of the land in the Market District? It has not been appraised; effectively, its value is a function of the market.

How will maintenance be affected in the parks where current maintenance facilities will be relocated to the Municipal Services Center? Greater efficiencies incurred by current staff should lead to improved effectiveness of services in these (and other) City parks. Ultimately, the plan should lead to more land area as these current maintenance sites are placed back into park uses.

Will there be further work on the redevelopment plan for SE 14th St.? Yes, the full MSC Master Plan report will include some strategies for redevelopment in the area. Additionally the MSC Master Plan will necessitate amendments to the SE Agribusiness Urban Renewal Plan which will address redevelopment in this area.

Is there expansion potential for the MSC? Yes, in addition to the area that has been identified for phase 2, areas northeast and southeast of the MSC site and contiguous to the areas shown for service yards have the potential for redevelopment and could potentially be utilized for City purposes.

What is the timing and cost for Phase 2? Timing for phase 2 is indefinite. Costs for Phase 2 will depend on timing and resulting cost escalation. In todays dollars, the project costs (inclusive of land acquisition, storm water/utility improvements, environmental clean-up, building and site construction, professional fees, equipment costs) is estimated at $45M.

What informationwasfoundin thestudyof the landfill? The study was intended


to locate the perimeter of the landfill and that perimeter indicated a significantly larger area than was previously suspected, making the area unbuildable for the Municipal Services Center. In general, we know that the landfill was an unregulated City dump site for residential use through the mid- 1900s and requires no further action by the IDNR (the regulating body for such sites), indicating that there is no known leakage occurring into the groundwater nor river.

City Council Meeting

The City Council took formal action on the findings of the preliminary Municipal Services Center Master Plan at the July 25, 2011 Council meeting. The action included:

A Resolution Approving Components of the Executive Summary of the Draft Municipal Services Center Master Plan Directing the City Manager to Proceed with Specific Actions to Advance the Municipal Services Center Project

1. Approval of the following Components of the Executive Summary of the Draft Municipal Services Master Plan and direction to incorporate into the final Master Plan:

a) The location of the Municipal Services Center and the portion thereof to be initially constructed. b) The City Services to be relocated in the first phase of the Municipal Services Center.c) The conceptual plan of the Municipal Services Center.

2. Authorized and directed to proceed with the following actions to advance the proposed Municipal Services Center:

a) To finalize the Master Plan. b) To proceed with the voluntary acquisition of the additional properties needed in the future to complete the Municipal Services Center as identified in the Master Plan Executive Summary, SUBJECT TO the City Council having first approved the acquisition by gift, negotiation or eminent domain of the property needed for the first phase of the facility. The process to set hearing to authorize acquisition of the properties needed for the first phase of the facility is the subject of a separate resolution to be considered on this date by City Council.c) To prepare a Request for Proposals (RFP) for design services for the facilities to be constructed in the first phase of the Municipal Services Center.


d) To communicate with the public entities and other institutions that operate services in the City (Polk County, State of Iowa, Des Moines Public Schools, DART, MidAmerican Energy and potentially others) to further explore potential collaborative opportunities related to the Municipal Services Center and surrounding area.

46 MUNICIPAL SERVICES CENTER MASTER PLANPLAN SUMMARY


Plan Summary


Plan Summary Study Area Selection ConsiderationsThe City of Des Moines studied several potential sites within the city to locate the Municipal Services Center. Of primary importance was the need to find an area that is centrally located and big enough to accommodate 40 to 60 acres of development. Other important considerations included access to primary transit corridors, flood protection, City land ownership, access to utilities, adjacent land use, and the potential for the MSC to be a catalyst for redevelopment.

The study area selected meets these considerations. It comprises approximately 175 acres of land and is centrally located in the city between SE 14th Street and SE 18th Street and between the Des Moines River and the new SE Connector.

Analysis of Existing ConditionsLand use in the area is mixed between light and medium industrial uses such as auto salvage yards, manufacturing, and production facilities interspersed with aging residential properties and smaller commercial businesses. The area in the southern portion is the location of an old capped landfill. Interim flood risk to the area is similar to existing downtown areas, which is protected by a levee system. Because the area is flat and relatively low lying, a storm water management strategy will be required. Primary access to the area is from SE 14th Street, but with the completion of the SE Connector additional access will be available from the north. See pages 53-81 for further information.

Program It is estimated that approximately 328,000 SF to 368,000 SF will ultimately be required to consolidate the various city departments into one facility. 84,000 SF has been identified for Phase One development. It will house the Parks Department and portions of the Engineering Department, both of which need to move from their present location at SE 20th and Scott to allow for SE Connector. The second phase for development includes relocating all of Public Works and Fleet, currently located at SE 5th Street, just north of the SE Connector. See pages 83-173 for further information. Master Plan RecommendationsThe plan recommends Phase One development proceeding as soon as possible. An 11.5 acre site along the north side of Scott Avenue is recommended because there will be a high degree of public visibility along the new SE Connector, it is easily accessible, and this site can be made contiguous by closing Scott Avenue and thus accommodating Phase Two development to the south. A total of 42 acres will be required for the entire development. See pages 175-191 for further information.


AnticipatedOperationalEfficiencies

There are a number of operational improvements that can be made which will result in significant savings. These savings result from extended vehicle life, better utilization of vehicles and resale of vehicles no longer required, improved employee productivity, improved service, and improved fuel consumption due to fewer miles logged, to name just a few. Excluding the sale of real estate that will no longer be needed by the City, the savings are estimated to be:

Phase One One Time Cost Savings $ 750,000 Annual Savings / Service Improvement $ 625,000

Phase Two One Time Cost Savings $ 2,250,000 Annual Savings / Service Improvement $ 1,875,000


Reuse or Removal of Existing City Facilities

The existing city facilities located at SE 20th and Scott will need to be removed to allow for the expansion of the SE Connector. The facilities located at SE 5th and Market Streets may be either reused or removed to allow for private development of the Market Place District. Other facilities located in various city parks, which will no longer be needed when the Parks department relocates all of their facilities in the new Phase One facility, will be either converted to other uses needed to support each park or will be removed and the area restored to park use. Currently these facilities are used to store equipment and maintenance supplies.

Economic Development

The proposed Municipal Services Center will provide opportunities for enhancement of an underutilized area and a demonstration of sustainability through reclamation of environmentally challenged land. The location of this significant public investment and community resource will also serve to assist in ongoing revitalization efforts along SE 14th Street, and spur new private sector economic investment with the increase in land value and added daytime workforce presence in the area. For further discussion of Economic Redevelopment Potentials see pages 184 and 185.

Existing Field Service Buildings

Due to the extension of the SE Connector, some of the City of Des Moines Public Works, Parks and Recreation, and Engineering Departments currently located at SE 20th and Scott Streets will need to be relocated to a new location. The master plan will also take into account the existing Public Works storage yard operations that is planned to be intersected by the SE Connector expansion. Due to the timing of Kemin Industries expansion into areas of this site that will remain after construction of the SE Connector, most of Public Works has temporarily relocated from the SE 20th and Scott Street site to 903 SE 22nd Street.

In addition to relocating uses at the SE 20th and Scott Street relocation, the City identified the current Public Works, Solid Waste, and Fleet Maintenance locations on E. 3rd, E. 4th, and E. 5th Streets to be part of the Market District Revitalization Plan. This means the City intends to eventually move these operations to a new Municipal Service Center. This is being identified as Phase Two. Once complete, the Municipal Service Center will consolidate many of the Citys aging buildings into one consolidated location capable of servicing most of the Citys departments well into the future.

The following sites were analyzed in detail: Parks and Recreation and Engineering operations located at SE 20th and Scott

Avenue Public Works operations located at 903 SE 22nd (temporary location) Public Works and Engineering operations located at 216 SE 5th Street/316 SE 4th

Street Solid Waste operations located at 110 SE 6th Street Fleet Services operations located at 212 SE Raccoon Street

The facilities at the above locations are in need of additional space for both operations and indoor vehicle storage. The City has outgrown the facilities as operations have grown over the last 30 years. With insufficient space to maintain and store vehicles, vehicle life is reduced. Currently all locations consist of outdated buildings that will require major repair and replacement if operations were to continue in these locations. The consolidation of these operations would allow the City to take advantage of the recommendations listed within this report.

Existing Study Area Conditions

The study area for the Municipal Services Center contains approximately 175 acres east of SE 14th Street and north of the Des Moines River. Land use in the area is mixed between light and medium industrial uses such as auto salvage yards, manufacturing, and production facilities interspersed with aging residential properties and smaller commercial businesses.

Existing highway oriented commercial businesses are located along the SE 14th Street corridor. North of Scott Avenue exists a large auto salvage operation operated by the Carroll Family Trust. The site will be impacted by the planned SE Connector right-of-way, splitting the salvage operation into north and south halves.

The south edge of the study area, north of the River, contains a capped landfill. Development on the landfill site will be challenged by existing fill, refuse debris, shallow groundwater, lower strength soils, and the potential for moderate to high plasticity clays. Since the landfill debris were not placed with strict moisture or density controls, the bearing strength of the soils for foundations cannot be assured. Expenses to remediate the site are insurmountable.

An extension of the downtown levee system separates the study area from the river. Access over the levee of SE 15th Street and Harriet allows public use of the boat ramp located on the river. The Downtown East Levee System extends along the Des Moines River adjacent to the study area. This levee starts upstream near the Des Moines Botanical Center and runs along the left (east) bank of the Des Moines River through downtown to near the WRA Wastewater Reclamation Facility at the downstream end.

EnvironmentalConsiderations(Soils+Brownfields)

Four primary classes of subsurface environmental considerations have been identified in the project area: remnants of the city landfill, leaking underground storage (LUST) sites, and sites with potential risk according to the SE Connector Environmental Impact Study, 2011, and wetlands mapping.

LandfillGeotechnical explorations of the landfill conducted by Terracon in May, 2011 for the City of Des Moines have located the western and northwestern edges. The southern edge is likely bounded by the levee and historic aerial photos suggest the landfill extended east to SE 21st Street, though this is not confirmed because testing was not conducted for areas not owned by the City. Presence of landfill debris impact the stability of subsoils, will impact footings, and pavement design.

The Debord-Dunbar Partnership conducted a planning study for the City of Des Moines in 1984 and included the known history of the Harriet Street Landfill. According to that study, the landfill was in operation from 1955 through 1971 and is estimated to contain approximately 3,388,000 cubic yards of refuse, excluding capping and fill material. Depths of the refuse ranged from 10 to over 40 and capping material ranged from 1 to 3 in depth. The report indicates refuse consisted of 40% residential, 50% commercial, 8% demolition, and 2% sewage sludge waste.

Referenced in the Debord-Dunbar study, a 1981 Terracon exploration of the landfill concluded the site was unsuitable for building loads, roads, underground utilities, and other appurtenances for development. The 2011 Terracon exploration reached a similar conclusion stating, We cannot predict the performance of foundations, floor slabs, pavements, and other structural elements supported on or above the existing refuse debris; therefore, we do not recommend placement of settlement sensitive structures in this area. Additionally, the current Terracon report indicates, The extent and exact contents of the landfill are unknown; therefore, we do not recommend excavating into the landfill materials or penetrating through the bottom of the landfill.

Alternative uses for the landfill may be possible, but should allow for significant settlement as the organic refuse below compresses. Operations such as exterior bulk storage and surface storage may be suitable for the site, however access drives and parking should be constructed of granular material to allow for settlement. Periodic regrading of site surfacing should be expected to address settlement. Further study is needed to understand the potential for surface uses on the landfill. No structures with footings and/or foundations that would disturb the landfill should be constructed.

Leaking Underground Storage Tanks (LUST)The Iowa DNR Interactive Mapping website shows the LUST sites indicated on the maps. The true extent and nature of the affected area associated with each site is not known. The 200 buffer indicates the area in which petroleum contamination may affect below grade plastic piping.


Environmental Impact Study SitesThe sites identified in the SE Connector E.I.S. document indicate auto salvage areas and other sites with low, medium, and high risk of contamination. Potential contaminated associated with the salvage use is likely manageable, but the full extent of clean-up is unknown until testing can be conducted. The level of risk indicates the likelihood of contamination, not the hazard such contamination, if present, poses. It is possible for additional contamination to exist beyond the initial E.I.S. research.

WetlandsThree wetlands are identified in the study area according to the US Fish and Wildlife Service wetlands mapping. This scale of mapping relies on identifying wetlands via aerial photography, soils maps, and other sources. For this reason, on-site delineation is required to accurately define the boundaries, types, and importance of a wetland. Mitigation measures may be required for disturbing wetlands, however the extent of mitigation and agencies involved in oversight would be identified during wetland delineation procedures.

The wetlands in the study area range from semi-permanently to seasonally flooded. Two of the three wetlands identified are due to man-made depressions associated with the railroad corridors at the north end of the study area.

The present wetlands can be coded per the U.S. Fish and Wild Life Service, National Wetlands Inventory as PSS1Cx, PEMFx, and PSS1A. Wetlands resulting from man-made conditions end an x in their coded designation.

STUDY AREA


Large Parcel Ownership

A large percentage of the 175 acre study area is owned by relatively few landowners. The City of Des Moines currently owns more than 85 acres in the southern portion of the study area; consisting of the retired Harriet Street Landfill, a compost facility leased to Metro Waste Management, and riparian open space north and south of the Des Moines River levee. Pine Ridge Farms, S&P Properties and the Carroll Family all retain ownership of multiple parcels, with a combined ownership of over 60 acres.


Existing Land Uses

When passing thru the study area, one easily detects an industrial character that transcends decades. Visible indicators include an old rail line that transects the northern half of the study area, abandoned parking lots adjacent to large industrial buildings, and unmaintained fields filled with retired automobiles. An eclectic mix of small commercial exists on the smaller parcels to the west, immediately adjacent to SE 14th Street. A few residences are scattered between Scott and Maury Streets.Positioned between Maury Street and the Des Moines River levee is the former Harriet Street Landfill and the Metro Waste Management Compost Facility. The Metro Waste Authority currently leases property from the City of Des Moines to operate a composting and bulk storage facility on the former landfill. Parallel to the river, a ribbon of vegetation offers wildlife habitat and outdoor recreation opportunities. On the southern edge of the study area, just east of SE 15th Street is the Harriet Street Boat Ramp, an important river access point for Des Moines Fire and Rescue, as well as for water recreation enthusiasts. Existing land uses were determined by comparing Polk County classifications, City of Des Moines zoning, and on-site observations.

STUDY AREA


Short Term Transportation DevelopmentOverview of Transportation Analysis

Immediate changes in the study area are largely tied to the SE Connector and the expansion of Kemin Industries. A significant improvement in site access and connectivity to the west, the SE Connector is scheduled to extend east to SE 15th Street by 2013. This extension will include reconstruction of SE 15th Street from the SE Connector south to Scott Street, providing a direct connection between the SE Connector and the Des Moines Municipal Service Center. In addition to great automobile access, the SE Connector will bring much needed pedestrian and bicycle connections via a multi-use trail that will run along the south side of the roadway.

Phase one of the master plan identifies acquisition of 11.5 acres immediately south of the future SE Connector and north of Scott Avenue. Scott Avenue will remain open between SE 15th and SE 18th until the SE Connector is expanded to SE 18th and phase two of the Municipal Service Center is constructed.

Mid Term Transportation DevelopmentAnticipated Interim Step, Depending on Funding

Likely mid-term improvements include the extension of the SE Connector to SE 18th Street. Scott Avenue will close beginning at SE 15th Street and extending about 1,200 to the east for phase two of the MSC. SE Connector extension to SE 18th Street would improve access to Kemin Industries and other businesses in the area and provide an alternative to the intersection of Maury and SE 14th Streets. Also, access will be improved to the Municipal Services Center with the addition of a right in right out westbound connection from the SE Connector.

The configuration of the SE Connector through this area will be a four lane divided roadway and will include a sidewalk on the north side and a 10 multi-purpose trail on the south side of the traffic lanes. SE 18th Street will be reconstructed south to Scott Avenue as part of this project. Due to funding constraints, there is currently no specific schedule for the extension of the SE Connector to the east. The next phase would extend from SE 15th Street to SE 30th Street although funding constraints may require that phase to be divided into smaller segments. This could include a separate project from SE 15th Street to SE 18th Street to facilitate Phase 2 of the Municipal Services Center.

In addition to the closure of Scott Avenue, rail lines running through the site will close. Railroad tracks and right of way will be abandoned between Scott Avenue and SE 18th Street. The existing rail line will then terminate on the east side of SE 18th Street.

A trail connection along SE 15th Street from Scott Avenue to Maury Avenue will be created. The long term transportation changes will allow this trail connection to continue on the west side of SE 15th Street south of Maury Street.

Long Term Transportation Development

Once regional infrastructure and stormwater improvements have occurred, the Municipal Services Center facility can expand to meet the Citys full needs. Truck and service traffic to and from the MSC facility will use SE 18th Street, Maury Street, and the SE Connector. The public entry will be off the existing SE 15th and Scott Streets.

To alleviate increased traffic in the area and to address long term growth and connectivity issues between the south side of Des Moines and downtown, the one-way pairs of SE 14th and SE 15th Street that serve as Highway 69 that currently begins south of Court Avenue would be extended south to begin at approximately Hartford Avenue, south of the Des Moines River. This plan was developed in the late 1990s as part of the Martin Luther King, Jr. Parkway environmental document; however, this concept would need to be updated and further developed in cooperation with the Iowa Department of Transportation. This improvement is not in the current program and is not funded. A preliminary review of the MSC location and revised concept was performed to confirm that the improvement to the state highway remains viable.

Pedestrian connections will extend south along the existing SE 15th Street corridor along the east edge via a 10 multi-purpose trail to Maury Street. Between Maury and Harriet Streets, the trail will continue along the east side of SE 15th and parallel the planned regional storm water conveyance area. South of Harriet Street the trail will encircle a regional detention basin and connect to the boat ramp located on the Des Moines River.

The SE Connector will continue to be constructed incrementally to the east, eventually connecting to Highway 65.

The combination of short and long term improvements to the study area (improved access, upgraded infrastructure, regional detention and redeveloped properties) will undoubtedly offer a more desirable environment for future redevelopment.

Flood Conditions and Considerations

Following the flooding event in 2008, the Corps of Engineers updated the Des Moines River regulatory flows to reflect changes in flood probability. These updates increased the flood flow frequencies over previous estimates. The table below indicates these flows in cubic feet per second (cfs).

Probability Saylorville Lake SE 6th Street

Previous New Previous New

0.1 (10-year) 17,000 17,300 40,400 44,100

0.01 (100-year) 34,000 53,400 87,000 107,500

0.002 (500-year) 50,000 73,800 - 142,000

The increases in the flood flows result in increases to the base flood elevations. These increases result in portions of the existing levees not meeting the freeboard requirements of 44 CFR 65.10. This code requires a minimum of three feet of freeboard above the base flood elevation. The City of Des Moines has retained a consultant to develop an updated hydraulic model of the Des Moines River to assess the impacts of the increased flows. Preliminary results indicate 100-year freeboard with the new flows ranges from above three feet as required to approximately 1.50 feet short of the requirement.

The City of Des Moines will utilize the new hydraulic model to develop options for either raising the levees or creating additional conveyance through the Des Moines River. Both options have the result of meeting the requirements of 44 CFR 65.10 to protect the areas behind the levee from a 100-year flood with three feet of freeboard. The timing of implementing either of these options is unknown at the time of this plan and dependant upon the availability of funding. In the long-term, the Municipal Services Center area will be part of the levee certification solution for downtown. Storm water management of the Municipal Services Center site will include design of the buildings to allow a faster recovery in the slight risk of flooding. In the interim, flood risk to the site is similar to existing downtown areas. To account for flood risk, buildings will be designed to allow a faster recovery in the slight risk of flooding. The current continuity of operations plan that covers emergency operations and public service will be updated for the new site. In the long-term, the Municipal Services Center area will be part of the levee certification solution for downtown.

The construction of this levee was authorized under the 1944 Flood Control Act and construction was completed in 1971. The system of earthfill levees and floodwalls has a designed protection elevation to the 100-year flood event with three feet of freeboard. Subsequent increases in the discharges have reduced the freeboard as discussed above. The entire system is inspected every five years by the Corps of Engineers with the last inspection being performed on April 26 and 27, 2010. The system includes both the levee/floodwalls as well as the flood gates that are closed during flood events to prevent water from back flowing behind the levee.

The site is located just east of SE 14th Street and approximately 2,000 feet north of the Des Moines River which is controlled by Saylorville Reservoir and the Army Corps of Engineers. From this point on the Des Moines River it is approximately 1 mile from the confluence of the Des Moines River and the Raccoon River, which is an unregulated waterway. This area was not affected by levee overtopping during the 1993 or 2008 flood events.


Utilities

Water and sanitary sewer service is available throughout the master plan study area. There is a 16-inch water main on the north side of Scott Avenue, a 12-inch water main on the south side of Maury Street, and an 8-inch water main on the east side of SE 15th Street. These water mains would provide adequate capacity to serve the Municipal Services Building at any location in the master plan study area.

Sanitary sewer is located as follows: 10-inch on SE Astor Street from Scott Avenue to Maury Street. 10-inch on Maury Street from SE Astor Street to SE 15th Street. 10-inch on SE 15th Street from Scott Avenue to Maury Street. 10-inch on SE 15th Street from Maury Street to Harriet Street.

These existing sanitary sewers are expected to provide adequate capacity to serve the Municipal Services Building at any location in the master plan study area.

The Wastewater Reclamation Authority (WRA) has an existing 6 x 7 RCB combined trunk sewer along an alignment at Railroad Avenue extending through the landfill area. The WRA has plans to extend a 144 RCP along a similar alignment within the next 1-2 years. While these sewers are not available for direct connection to serve the master planning area, it is important to avoid them in any future storm water conveyance improvements along SE 15th Street.

Electric, natural gas, and telephone services are all available within the master plan study area. MidAmerican Energy has services for natural gas and electric on Scott Avenue, SE 15th Street, SE 15th Court, and SE Astor Street. Qwest has telephone lines on Scott Avenue, SE 15th Street, SE Astor Street, and Maury Street.

The franchise utilities are expected to have adequate capacities for the full construction of the facility. Level 3 communications and Verizon will need to relocate fiber optic communication lines located along the old train track alignment northwest to southeast through a portion of the Phase 2 building.

There are many deficiencies with the existing storm sewer system in the project area. The current system has capacity for less than a 1-year storm event and experiences frequent flooding. Storm sewer modifications will be needed for the project. Storm sewer in the master plan area is reflected on the existing utilities drawing. The drainage area at the outlet to the levee for the master plan area is approximately 160 acres. The capacity of the existing storm sewer system is generally less than the 1-year storm event with the critical capacity restriction being the section between Maury and the outlet at the levee. This storm sewer capacity deficit results in routine flooding of the intersections of SE 15th and Maury and SE 15th & Scott with depths up to 2 feet deep reported. There is currently limited or no on site detention of storm water within this drainage area.

84 MUNICIPAL SERVICES CENTER MASTER PLANBUILDING PROGRAM PROGRAM SUMMARY


Program Summary Review of current operations for the Citys field service departments show that all departments are in need of better and more productive, centralized facilities for both operations and vehicle storage. Because of limited financial resources it is recommended that the project be constructed in two or more phases, with the first phase addressing the immediate needs of relocating Parks & Recreation Service Center and Engineerings Traffic and Transportation department at the SE 20th and Scott Street site. The second phase would relocate the entire Public Works and Fleet operation currently located at 903 SE 22nd Street and within the existing Citys Market District area on the southeast side of downtown.

It is estimated the City will need to provide approximately 84,000 square feet for Phase One and 273,000 square feet for Phase Two, all of which would be located on approximately 40 acres of contiguous land within the study area. Phase Two will also require a new salt storage facility, (2) fuel islands and a cold storage building in order to meet the current and future needs. Over the next 10-20 years this site may eventually accommodate other entities such as Community Development Offices from the Armory and the Engineering Department from City Hall.

The objective of this plan is to offer recommendations to assist the City in constructing a cost-effective, technically-operational state of the art Municipal Services Center with the flexibility to accommodate future growth and changing technology. This plan, once implemented will greatly enhance the Citys ability to deliver services to the residents and visitors to the City of Des Moines. In addition the City will incur substantial savings through various efficiencies and actions such as:

By consolidating the numerous locations and operations, the City is left with one centralized facility, reducing overall budgets and utility expenditures.

By consolidating operations, the opportunity exists to increase staff efficiency and possibly reduce personnel compliments by attrition.

Through consolidation vehicle use can be maximized reducing the overall number of vehicles and vehicle replacement requirements.

Consolidated operations in state-of-the-art facilities lead to increased productivity.


The tasks have focused on data gathering, conceptual designs, and site location and estimated costs for the new facility. Specifically, the locations and departments reviewed include:

Phase One - SE 20th & Scott Avenue Parks and Recreation Service Center Parks and Recreation Administration Parks and Recreation Satellite Operations Engineering Traffic and Transportation Signal Shop & Street Marking Shop Sign/Parking Meter Shop Survey & Test Lab

Phase Two - 216 SE 5th Street

Public Works operations located at 903 SE 22nd (temporary location) Public Works Administration Public Works Streets, Vehicle & Equipment Storage Public Works Storage Yard Barricade Storage Bridge/Street Cleaning, Blinker, Parks Paint & Sidewalk Shop Radio Shop Building Maintenance Forestry

Phase Two - 110 SE 6th Street Public Works Solid Waste, Vehicle & Equipment Storage Fleet Services Gas Island

Phase Two - 316 SE 4th Street Public Works Sewers, Vehicle & Equipment Storage

Phase Two - 212 SE Raccoon Street Fleet Services

Future Phases 400 Robert D Ray Drive Construction Support Building Inspections Neighborhood Inspections Vector Building


As part of this planning process our team used the following approach to accomplish these planning objectives including performance of the following steps:

Oriented project team to assess overall departmental requirements. Interviewed key employees to understand critical assumptions, rationale,

operational nuances and attributes for new areas. Collected existing data such as:

Vehicle & Equipment inventories Site Plans Past Studies & City generated documents Skill resources and staffing levels

Modeled all areas to consider design capacity and resource requirements

The study proceeds with programming and planning recommendations and concludes with a conceptual site plan, phasing plan and a building plan configuration. The planning efforts focused on the following four areas:

Des Moines Public School System DART Mid-America Energy Polk County State of Iowa Satellite Facility Operations Center Mechanic Staffing Analyses

The new Municipal Services Center, without question, will cost millions of dollars to construct. We have provided many small operational changes that can streamline operations, and reduce the new construction footprint. It is not within our scope of services to study the outsourcing of major services. We recommend the City of Des Moines confirm what operations will actually be present in the Municipal Services Center.

Emergency Operation: Snow Removal Flood Control, Debris Cleanup

Staff members from most essential core services are used to provide emergency services such as snow and ice control, and wind and flood emergency response services. Reduction in emergency services should never be jeopardized, and it is possible that all current services are, in fact, efficient and cost-effectively provided currently under public/private partnerships.


Building Program Summary

The following table shows the proposed Building Program by department for the MSC.

*To facilitate the broad departmental consolidation and collaboration recommended by this plan, City standards and/or policy to coordinate office size and program consistency among similar level positions across departments should be developed. At the time of this study, no such standards/policy existed for the City; the recommended program for office space is commensurate with the consultants experiences with other municipalities.

Phase One Program


Phase One Site Plan

This facility will meet the immediate needs of the city to combine aging facilities and vacate land slated for the expansion of Kemin Industries and the SE Connector. The initial Municipal Services Center 11.5 acre campus includes an 84,000 square foot building for the Parks and Engineering Departments administrative and shop use. Scott Avenue will remain open to SE 20th and serve as the primary access for the public and yard spaces. The public will enter on the west side of the facility, either using the visitor drop-off or parking in the approximately 150-space parking lot. The north and west edges of the property will be used for stormwater detention facilities that could include a multi-use trail for recreational and wellness use.

A secondary access road connects the west visitor parking to the east side of the property. The drive also provides access to the north edge of the building for fire suppression. Yard space is provided on the east side of the phase one building. The primary public face of the building will be the north-west corner facing both SE 15th Street and the SE Connector.

Zoning

The current zoning of the Phase One properties is M-2 Heavy Industrial. The Phase One Zoning is expected to be rezoned to a Planned Unit Development (PUD) zoning classification. This will allow for future flexibility of the property as well as outside storage. The boundary of the area that will be rezoned to PUD is to be determined. Rezoning of the area to PUD will take place after property acquisition which will go through the Plan and Zoning Commission and City Council. The rezoning to PUD will need to go through the Plan and Zoning Commission for review and approval. Subsequent phases are subject to amendment of the PUD and Development Plan review.

The bulk regulations for the PUD would follow the requirements of the C2 Zoning for building setbacks and landscaping requirements.

Lot setbacks: Front yard: 25 feet, minimum. Side yards: For all permitted nonresidential uses, ten feet when the use is adjacent

to any R district and 25 feet when the use is adjacent to a street line; otherwise, none is required.

Rear yard: none required, except when adjoining any PUD, R or C-0 district, in which case ten feet, minimum.
