SAINT PAUL, MINNESOTA 55102 GEORGE LATIMER (612) 298-4323 MAYOR August 19, 1987 President John Drew and Members of the City Council 713 City Hall Dear President Drew and Members of the City Council: The Metropolitan Surface Water Management Act of 1982 requires that water management in the Twin Cities area be guided by watershed plans which encourage intergovernmental cooperation. Each watershed is to have its own plan, created by its watershed management organization or district. Cities within each watershed participate in the creation and review of each plan. When all applicable watershed plans have been adopted, each city must then revise its plans and/or procedures to conform to all applicable watershed plans. Saint Paul will be subject to five watershed management plans. One plan, the Ramsey-Washington Metro District Plan, has already been adopted. The City has now reached the stage of reviewing two additional plans, those of the Central Ramse_y and Southwest Ramsey Watershed Management Organizations. The Planning Commission has found each of these plans to be consistent with the Saint Paul Comprehensive Plan and has identified several issues of municipal planning concern which should be forwarded to the respective watershed management organizations. The areas of planning concern involve ways in which the watershed management organization can be more helpful in providing information and guidance to member communities. I am pleased to transmit to you the Planning Commission resolution and accompanying staff report for each plan. I recommend that they be supported and forwarded to the relevant watershed management organization and to the Water Resources Board.

Local units of government having territory within a particular WMO are required to adopt a local water management plan, a capital improvement program, and official controls as necessary to bring local water management into conformance with each relevant watershed plan. Six separate watersheds cover territory within Saint Paul's city limits. Saint Paul is expected to conform with WMO plans for five of these watersheds. The only land in Saint Paul included in the sixth watershed is Pike Island (State-owned and undeveloped) ; thus, Saint Paul is not required to conform to the WMO plan for this watershed. Of the five WMO plans governing Saint Paul, only one has been adopted. The plan for the Ramsey-Washington Metro Watershed District was approved by the Water Resources Board and adopted by the District early in 1987. Plans for the Central Ramsey and Southwest Ramsey WMOs are now being reviewed by member municipalities. The plans for Saint Paul's other two watersheds have not yet been released for review. The following staff report addresses the draft Stormwater Runoff and Water Quality Management Plan which the Southwest Ramsey Watershed Management Organization transmitted to the City of Saint Paul for review and comment. The Southwest Ramsey WMO includes all or part of four municipalities or goverrunental units in southwestern Ramsey County--Saint Paul, Falcon Heights, the State Fairgrounds and the University of Minnesota-Saint Paul Campus (see attached map) . In Saint Paul, it includes essentially all of Planning _ Districts 9, 14 and 15, and portions of Districts 11, 12, 13 and 16. . . . <��-r-�.�� August 6, 1987 Page Two To conform to each WMO plan, Saint Paul may need to revise its Zoning Code and its site plan review process. The Saint Paul Sewer Division will have the primary responsibility for developing new City water management plan requirements and new Zoning Code provisions. The Sewer Division, along with the Division of Housing and Building Code Enforcement, will also be responsible for enforcing the new requirements through the building and site plan review processes. AUTHORITY FOR REVIEW The Metropolitan Surface Water Management Act of 1982 provides for review of watershed management plans by all cities having territory within each watershed. It further directs that any city which expects that substantial amendment of its local comprehensive plan will be necessary in order to bring local water management into conformance with the watershed plan shall describe as specifically as possible, within its comments, the amendments to the local plan which it expects will be necessary. The City's Planning Commission ordinance provides that the Planning Commission shall serve as an advisory body to the Mayor and City Council on municipal planning matters. MANAGEMENT ISSUES AND STRATEGIES The Southwest Ramsey WMO has identified seven surface water management issues and has devised strategies for dealing with each issue. The following summarizes each issue and considers to what extent each corresponds to issues and strategies identified in the Saint Paul Comprehensive Sewer Plan. 1. Intermember Stormwater Runoff Management - Issue: Several drainage problem areas were identified using HYDRO, a computer model developed by the City of Saint Paul to analyze depth and volume of runoff and rates of peak inflow and outflow for minor watersheds. These problems consist of minor flooding during 5-year, 24-hour storms due to inadequate detention pond storage capacity and inadequate system inlet capacity. - WMO Management Strategy: As described above, the WMO plan identifies several problem areas involving more than one member of the WMO. No alternative solutions are proposed to these problems. Instead, members are encouraged to cooperate to provide control adequate to satisfy the WMO. The WMO plan states that the WMO may elect to become involved if solutions are not attainable through the cooperation of inembers. . � � ��i� August 6, 1987 Page Three - Relationship to Saint Paul Comprehensive Plan: The City's Comprehensive Sewer Plan on stormwater management (March 1984) recommends that Saint Paul seek the cooperation of the State of Minnesota, the Metropolitan Waste Control Commission, the Metropolitan Council and suburban communities in reaching the most beneficial solution to watershed problems which affect numerous governmental agencies (Recommendation #4, p. 123) . 2. Combined Sewer Overflow - Issue: The City of Saint Paul's Comprehensive Sewer Plan--Part I, Stormwater Management, March 1984, identifies where combined sewers are located and what problems are associated with them. The City's plan also provides a summary of proposed solutions and cost estimates for these solutions. A central component of Saint Paul's plan is a vigorous program to separate sanitary and storm sewers. This program also requires separate sanitary and storm interceptors (large sewer lines which collect sewage from a number of trunk lines) . - WMO Management Strategy: Support Saint Paul's effort; be aware of Saint Paul projects that may benefit intercommunity stormwater management. - Relationship to Saint Paul Comprehensive Plan: The City's Comprehensive Sewer Plan on stormwater management (March 1984) recommends separate sewers in all new construction and a program of sewer separation in areas of the city served by combined sewers (Recommendations #1, 2, 3, 7, 9, 11 and 14; pp. 123, 124) . The same plan also makes other recommendations regarding solutions to problems of combined sewer overflow, including a roof drain disconnection program, a program for developing regional stormwater ponding areas, and a program to minimize stormwater runoff on construction sites (Recommendations #12, 13, 15 and 16; pp. 123, 124) . An amendment to the Comprehensive Sewer Plan on stormwater management (January 1986) establishes an accelerated ten year sewer separation program funded at $15.4 million per year with Saint Paul's share fixed at $4.8 million per year (p. 30) . This amendment was a result of new State and federal mandates and funding commitments. . � , � ��i�� August 6, 1987 Page Four 3. Fairgrounds Runoff Water Quality - Issue: Significant amounts of litter and animal manure would be washed into the stormwater�collection system if rainfall occurs during the 12 days of the State Fair. This untreated waste, particularly the animal manure, would likely cause pollution problems in waters receiving the discharge. - WMO Management Strategy: Support the efforts of the State Fairgrounds to control litter and debris, and require the Fairgrounds, as part of its local plan, to manage Fairgrounds runoff properly throughout the year. - Relationship to Saint Paul Comprehensive Plan: The City's Comprehensive Sewer Plan on stormwater management (March 1984) recommends that Saint Paul seek the cooperation of the State of Minnesota, the Metropolitan Waste Control Commission, the Metropolitan Council and suburban communities in reaching the most beneficial solution to watershed problems which affect numerous governmental agencies (Recommendation #4, p. 123) . 4. University of Minnesota-Saint Paul Campus Runoff Quality - Issue: Fertilizers, herbicides, pesticides and animal wastes are potential runoffs from University land. Agricultural experimentation at the Saint Paul campus involves commercially available fertilizers, herbicides and pesticides. Moreover, a one-acre plot is used to test herbicides that are only available for experimental use. Finally, the University uses recycled animal wastes as fertilizer in some areas. - WMO Management Strategy: Encourage the University to continue using agricultural practices which minimize runoff pollution; encourage the continued cooperation of the University with the Minnesota Pollution Control Agency involving permit programs and water quality improvement practices. - Relationship to Saint Paul Comprehensive Plan: The City's Comprehensive Sewer Plan on stormwater management (March 1984) recommends that Saint Paul seek the cooperation of the State of Minnesota, the Metropolitan Waste Control Commission, the Metropolitan Council and suburban communities in reaching the most beneficial solution to watershed problems which affect numerous governmental agencies (Recommendation #4, p. 123) . . . �� August 6, 1987 Page Five 5. Hidden Falls-Crosby Farm Regional Park - Issue: This park is located on the Mississippi River in the area where Interstate 35-E crosses the river. It was created and funded to provide recreational opportunities for local and regional residents. However, flooding associated with Crosby Lake inhibits the use of the park for recreational purposes. - WMO Management Strategy: Encourage the City of Saint Paul to reduce, where practicable, the volume of runoff into Crosby Lake to insure quality recreation opportunities. - Relationship to Saint Paul Comprehensive Plan: Not specificially addressed in the City's Comprehensive Sewer Plan on stormwater management. The City's Plan for Parks and Recreation notes that the natural resources of the city's regional parks should be more fully utilized for programs focusing on nature and ecological systems which appeal to residents of all ages (p. 8) . 6. Bluff Erosion - Issue: The steep bluffs along the Mississippi River may erode along their bluff lines if not properly managed. Most of the bluff lines within the watershed are publicly owned as parks and open spaces. As such, they are protected from impacts due to development. However, natural processes may result in erosion if the bluff lines are not stabilized. - WMO Management Strategy: Support the City of Saint Paul's efforts to minimize bluffline erosion and coordinate with the Ramsey Soil and Water Conservation District to insure program compatibility with watershed and local level policies and strategies. - Relationship to Saint Paul Comprehensive Plan: This issue is discussed in the "Saint Paul Mississippi River Corridor Plan" (updated August 1979) . Environmental policies/objectives in this plan include statements that damage to lands and surface waters from erosion and sedimentation shall be minimized, and that slopes which are susceptible to severe erosion should be maintained in a natural state to avoid damage from erosion, increased runoff and sedimentation (p. 11) . . . ��7�� August 6, 1987 Page Six 7. Water Quality Management - Issue: Water quality should be protected in the protected waters and wetlands of the watershed. Protected waters consist of Crosby Lake and the Mississippi River. There are also three wetlands--one on the University of Minnesota-Saint Paul campus and two in Saint Paul (Crosby Lake and the Fairview North Pond between the Pierce Butler Route and the Burlington Northern Railroad) . - Management Strategy: Each city should develop plans for housekeeping, source controls and construction site management. - Relationship to Saint Paul Comprehensive Plan: The City's Comprehensive Sewer Plan on stormwater management (March 1984) contains numerous such recommendations, including a roof drain disconnection program, the development of regional stormwater ponding, development and redevelopment site requirements, the introduction of new technologies to protect the environment, street sweeping and the cleaning of catch basin sumps. STAFF RECOMMENDATION The Saint Paul Sewer Division will have the primary responsibility for developing and enforcing new city requirements to implement the watershed district plan. Sewer Division staff has reviewed the proposed watershed management plan and recommends that the City of Saint Paul support the adoption of the plan. Specific Sewer Division recommendations are contained in the attached memo from Roy Bredahl to A1 Lovejoy dated July 27, 1987. Planning Division staff also recommends that the City of Saint Paul support the adoption of the proposed Central Ramsey Watershed Management Plan and recommends forwarding the following comments to the Watershed Management Organization: l. The Saint Paul Comprehensive Plan does not require amendment in order to bring local water management into conformance with the proposed Watershed � Management Organization plan. 2. Analysis of flooding problems should be based on 100-year events. 3. Sufficient data should be provided to enable public bodies to plan for intercommunity flow of runoff. 4. Stormwater runoff management costs to affected public bodies should be estimated where appropriate. . , , , �� August 6, 1987 Page Seven 5. The Watershed Management Organization plan should be as specific as possible in defining expected actions and standards for controlling and treating various types of flooding and runoff, and in determining equitable methods of cost-sharing among members. 6. The State Fairgrounds and the University of Minnesota-Saint Paul campus should demonstrate that their plans will not result in problems for Saint Paul or its sewer systpm. 7. Before finally adopting special requirements for stormwater management plans in critical areas, the Watershed Management Organization should make sure that the implementation of new regulations is feasible and that both small and large developers can readily obtain the engineering expertise needed to develop stormwater management plans. 8. The Watershed Management Organization should provide adequate training for City inspectors and plan reviewers in enforcing stormwater runoff and water quality management requirements. 9. The City supports the retrofitting of existing conveyance systems with settling basins when feasible, but recognizes potential problems with obtaining suitable land and public acceptance. 10. The City supports Watershed Management Organization studies to determine what capital improvements are needed and how they will be financed. ECONOMIC DEVELOPMENT COMMITTEE ACTION At its meeting of August 5, 1987, the Economic Development Committee discussed a draft staff report and draft recommendations with Planning Division and Sewer Division staff. The report and recommendations have been revised in accordance with discussion at that meeting. The committee unanimously recommended approval of the proposed resolution, as revised. • � x N Z : Q � � � e0 C oc .W � � +r .�.. o � � � � � � ° � � W � � � W � o = o � � a � �o ,� s � �, � � �- � � = W � - N O � a `° � _ u; 3 � ,, � r , . � •.� W � �!'f M 1 O r � � : �O � � \\ ' � so b� � a NOSH�d�_� � � ` ��`�,�'r . � ��d� �-' J \ '��6� �nr � •:: iiiiws , .,� o, �n�v�� _ .�� d �� : '� 3�ia ,�-,' ,,� �" d ` `� � �; , � . `n•� ' . t �� W i I I \ � V �d`..�" � 4 c» a LL�� I; �;, �, .-. � � J � , o y� �� 'r: :� � od., i <. � .�- � � '� � i ,, a a ;. �� n:v� - - ,.-3�t �?j i''� '6 � b.

These Watershed Management Organizations (WMO's) are admittedly loosely organized relying on the individual member communities to perform most regulatory, administration and construction functions. As planning organizations, the WMO's set general guidelines for the local activities, provide forums to settle disputes and oversee conformance with the plans. In reviewing the plans, the Sewer Division tried to anticipate the requirements of other agencies and certain city needs that have to be addressed. Therefore, we submit the following recommendations: These Watersheds have lost many wetlands to land development. Therefore, the remaining water resources are particularly.precious. Certain guidelines are needed to protect these resources in terms of quantity and quality. CENTRAL RAMSEY WATERSHED Our conunents center around Chapter V of the Plan. 1. Combined Sewer Overflows The WMO is not directly involved in St. Paul's sewer separation except as it relates to the management of intercommunity flows. There should be a procedure for determining the cost sharing for structures that serve intercommunity flows. 2. Intercommunity Stormwater Runoff Management a. Solutions to the Godfried Pit overflow problem (P. V-10) appear to be based on a 5-year storm design. This may not be appropriate because normally such ponding areas are designed for a 100 year event. This project could create hidden costs to St. Paul if it results in more overflow from Lake Conto. �� b. The proposed solution to the McCarrons Lake overflow problem may conflict with St. Paul's plan for the Arlington-Jackson Pond and Trout Brook separation. It is unclear what would happen during a 100 year event and unclear whether St. Paul will be providing extra storage capacity in the pond for add'itional overflow. Mention should be made of the role of the Minnesota Department of Transportation. c. The discussion on the Arlington-Jackson Pond (P. V-18) should mention cost sharing of a joint-used facility. d. The section on Intercommunity Stormwater Runoff Management (p.V-20) contains no section estimating the costs to the Central Ramsey (WMO) . e. The plan does not contain sufficient data for St. Paul to design and plan for intercommunity flows. 3. LAKE MANAGEMENT It is true that the Clean Lakes Program for Lakes Como and McCarrons are being controlled by others. The WMO should have an active policy of monitoring the progress of these efforts. 4. WATER QUALITY MANAGEMENT a. The section on source controls of pollutants is vague. There should be guidelines. St. Paul may not be in the position to provide for the control and treatment of 1 year storm runoff on new developments or redevelopments (p. V-23) . Is there some minimum acreage limitation applicable to this standard? b. It will be difficult to prepare a plan for control of road deicing chemicals and construction site management to maint-ain water quality (p.V-23) , unless reasonable guidelines ar�. established. SOUTHWEST RAMSEY WATERSHED Our comments center on Chapters V and VI of the plans. 1. Intermember Stormwater Runoff Management The plan does not contain sufficient data for St. Paul to design and plan for intermember stormwater flows (p. V-2) . 2. Combined Sewer Overflow The WMO is not directly involved in St. Paul's sewer separation except as it relates to the management of intercommunity flows (p. V-16) . There should be a procedure for determining the cost sharing for the St. Anthony Park facilities that serve several members of this watershed. 3. Fairgrounds Runoff Water Quality The plan indicates that a portion of the Fairgrounds will remain served by combined sewers because of water quality problems V-19) . This matter will have to be studied further. The Metropolitan Waste Control Commission and the Minnesota Pollution Control Agency should be involved in establishing these criteria. St. Paul is concerned because the excessive inflow of stormwater into existinq regional sanitary interceptor could cause problems in St. Paul's system. . . • , ��-i� 4 . Hidden Falls-Crosby Lake Regional Park There should be a list of specific steps which the city should take to perform the work required for Crosby to provide recreational opportunities (to meet the 2B Classification P.V-24) . Excessive runoff may not be the problem. 5. Water Quality Management The section on source controls on pollutants is vague (p. V-27) . There should be guidelines. This is especially important as it relates to road deicing chemical control and construction site management. 6. Chapter VI - Implementation (Page VI-I - Item 2) The statement is made that the city should meet guidelines relating to stormwater detention and treatment. These guidelines have not been established in this report. The Minnesota Department of Transportation is involved in this matter also. Also attached are some recommended changes to your memo to the Planning Commission.
