City of Mounds View Staff Report September 4, 1998 Page 2 7.46 miles of MSA streets were identified for reconstruction at an estimated cost of$6,827,000 (excluding the surface water component). Funding was estimated as follows: MSA $5,532,000, County turn back at$748,000 and assessments at$2,305,000. Local Streets 24.31 miles of local streets were identified for reconstruction at an estimated cost of$14,766,000 (excluding the surface water component). Special assessments were estimated at$5,450,000. Surface water Surface water improvements were estimated at$1,318,000. The MSA funding noted above includes a partial reimbursement relating to the surface water component of the project. In addition, a portion of the cost would be assessed at a set amount per residential or commercial lot. Additional funding would be provided from the surface water fund. Changes in Street Standards Existing local street standards call for a 30 foot wide street. The City presently has 31.99 miles of local streets. For every 2 foot reduction in the standard width to the overall system,the City could save approximately $610,000. As noted above,the projects call for reconstruction of 24.31 miles of streets; if the width was reduced,the following savings would result: Street width Dollar savings Percent savings 28 ft $465,000 3.15% 26 ft $930,000 6.30% 24 ft $1,395,000 9.45% For two way traffic,the road width can not be less than 24 feet. Removal of curb and gutter Existing local standards require curb and gutter. MSA standards require curb and gutter. If curb and gutter was removed from local streets, construction costs would be reduced by approximately $1,600,000 or 10.8%. Current literature indicates that roads will deteriorate at a faster rate and requiring more frequent maintenance without curb and gutter. We were unable to project additional maintenance costs nor did we project an earlier overlay/reconstruction due to removing curb and gutter. Cash flow projections Using existing policies and no additional City funding, at the end of 50 years,the City's street construction fund would have a deficit of$47,997,000. If curb and gutter is removed,the projected deficit is $35,000,000. However, as noted above,we did not factor in additional maintenance costs nor a faster overlay/reconstruction that would appear to be required if curb and gutter is removed. If the County reconstructs Spring Lake Road,the deficit increases to $58,092,000. If the County reconstructs Spring Lake Road but curb and gutter is removed from all local streets, the projected deficit is $45,075,000.
