3 Woodfield Park Parking Study I. INTRODUCTION: DMc Engineering was retained by the Aliso Viejo Community Association to perform the following work efforts relative to potential development of five (5) parking lot and connective roadway improvement alternatives at Woodfield Park located at/near the intersection of Woodfield Drive and Pacific Park Drive in the City of Aliso Viejo: 1. Prepare an engineering and feasibility written report identifying property line constraints, easement constraints and jurisdictional boundary constraints for five (5) improvement alternatives. 2. Prepare parking lot and connective roadways concepts for five (5) improvement alternatives. These concepts will utilize Google Earth as its base map. 3. Prepare construction cost estimates for each of the five (5) improvements alternatives. The five (5) improvement alternatives identified by the Aliso Viejo Community Association are as follows and depicted on Exhibit A: 1. Proposed parking lot 3A 2. Proposed connector roads 3. Proposed parking lot 1A 4. Proposed parking lot 4 5. Proposed parking lot 5 The parking lot identification numbers above correspond with an exhibit prepared by LSA titled Project Site and Parking Locations (Figure 1). A copy of which is enclosed herein as Exhibit B. The work effort began with a field walk with vested stakeholders along with multiple follow-up field visits to evaluate each of the alternatives.

4 Woodfield Park Parking Study II. PROPERTY LINE, EASEMENT AND JURISDICTIONAL BOUNDARY CONSTRAINTS DMC Engineering acquired a preliminary title report for the subject property in order to evaluate property line, easement and jurisdictional boundary constraints for each of the five (5) improvement alternatives. The results of the effort are noted below and depicted on Exhibit C. A. PROPOSED PARKING LOT 3A 1. Property Line Constraints The easterly limits of alternative 3A abuts the easterly property line of the park, which is the westerly right-of-way for Aliso Creek, a regional drainage facility in the favor of the County of Orange Flood Control. 2. Easement Constraints Agencies with existing easement rights within proposed parking lot 3A: County of Orange relative to existing flood plain easement. County of Orange relative to existing access, riding and hiking easement. County of Orange relative to existing access easement. County of Orange relative to existing storm drain easement. County of Orange relative to easement grant for access over county property. 3. Judicial Boundary Constraints The County of Orange and the City of Aliso Viejo are the regulatory agencies that any construction plans will need to be cleared by and/or processed with. This is due to the County of Orange being the holder of existing easements within this proposed improvement alternative. The City of Aliso Viejo is the regulatory agency responsible for issuing appropriate permits. B. PROPOSED CONNECTOR ROADS The connector roadways are conceptually shown as one way traffic flow around the park beginning at proposed parking lot 3a and ending at the north end of proposed parking lot 5. The roadways are shown as a minimum width of 14 feet. 1. Property Line Constraints As mentioned above, the park s northerly property line is located adjacent to the southerly right-of-way of the San Joaquin Hills Transportation Corridor. There appears to be an area adjacent to the northerly property line that could accommodate necessary vehicular access that would provide circulation between areas 4 and 5, thus creating room along the park subject property.

County of Orange relative to existing access, riding and hiking easement. County of Orange relative to existing access easement. County of Orange relative to existing storm drain easement. County of Orange relative to easement grant for access over county property. 3. Judicial Boundary Constraints The County of Orange and the City of Aliso Viejo are the regulatory agencies that any construction plans will need to be cleared by and/or processed with. This is due to the County of Orange being the holder of existing easements within this proposed improvement alternative. The City of Aliso Viejo is the regulatory agency responsible for issuing appropriate permits. C. PROPOSED PARKING LOT 1A 1. Property Line Constraints None 2. Easement Constraints Agencies with existing easement rights within proposed parking lot 1A: Aliso Water Management Agency easement for water lines. County of Orange relative to existing flood plain easement. County of Orange relative to existing access, riding and hiking easement. County of Orange relative to existing access easement. County of Orange relative to existing storm drain easement. County of Orange relative to easement grant for access over county property. 3. Judicial Boundary Constraints The County of Orange and the City of Aliso Viejo are the regulatory agencies that any construction plans will need to be cleared by and/or processed with. This is due to the County of Orange being the holder of existing easements within this proposed improvement alternative. The City of Aliso Viejo is the regulatory agency responsible for issuing appropriate permits. D. PROPOSED PARKING LOT 4 1. Property Line Constraints None 2. Easement Constraints Agencies with existing easement rights within proposed parking lot 4: County of Orange relative to existing flood plain easement. County of Orange relative to existing access, riding and hiking easement. County of Orange relative to existing access easement. Page 3

Judicial Boundary Constraints The County of Orange and the City of Aliso Viejo are the regulatory agencies that any construction plans will need to be cleared by and/or processed with. This is due to the County of Orange being the holder of existing easements within this proposed improvement alternative. The City of Aliso Viejo is the regulatory agency responsible for issuing appropriate permits. E. PROPOSED PARKING LOT 5 1. Property Line Constraints None 2. Easement Constraints Agencies with existing easement rights within proposed parking lot 5: Aliso Water Management Agency easement for water lines. County of Orange relative to existing flood plain easement. County of Orange relative to existing access, riding and hiking easement. County of Orange relative to existing access easement. County of Orange relative to existing storm drain easement. County of Orange relative to easement grant for access over county property. 3. Judicial Boundary Constraints The County of Orange and the City of Aliso Viejo are the regulatory agencies that any construction plans will need to be cleared by and/or processed with. This is due to the County of Orange being the holder of existing easements within this proposed improvement alternative. The City of Aliso Viejo is the regulatory agency responsible for issuing appropriate permits. Page 4

7 Woodfield Park Parking Study III. PARKING LOT AND CONNECTIVE ROADWAY IMPROVEMENT ALTERNATIVES A. PROPOSED PARKING LOT 3A Concept proposes 48 new standard parking stalls and 3 new ADA compliant stalls, one (1) new driveway at Woodfield Street (connector A-1 ), New sidewalk elements connecting the proposed parking lot 3A sidewalk to the existing public sidewalk at Woodfield Street. Removal of existing sidewalk at the east end of parking lot 3 and replacing with a one way 14 wide asphalt road shown as connector A-2 and connector road B. This is depicted on Exhibit A. B. PROPOSED CONNECTOR ROADS Concept proposes four (4) new connector roads being a minimum of 14 wide asphalt road. This is depicted on Exhibit A. C. PROPOSED PARKING LOT 1A Concept proposes 14 new standard parking stalls and new sidewalk adjacent to the existing connector roadway on the west side of the park. This is depicted on Exhibit A. D. PROPOSED PARKING LOT 4 Concept proposes 58 new standard parking stalls, utility road 1 for maintenance, pedestrian sidewalk and proposed connector road D. This is depicted on Exhibit A. E. PROPOSED PARKING LOT 5 Concept proposes 57 new standard stalls, with pedestrian sidewalk connection to existing park sidewalk and connector road D. Modification options have been identified for connector road D regarding obtaining an easement for roadway purposes on the adjacent property to the north owned by the San Joaquin Hills Transportation Corridor and the County of Orange or keeping the proposed roadway on park property with modifications to baseball field 5 to accommodate connector road D. This is depicted on Exhibit A. Page 5

8 Woodfield Park Parking Study IV. ESTIMATED CONSTRUCTION COSTS Estimated construction costs for each of the five (5) improvement alternatives are detailed in Exhibit D. These estimated costs are derived from the visual field walks, development improvement alternatives and historical cost data for similar projects. The costs do not include plan preparation, processing, permit fees or construction management. Page 6
